MACHINE FOR APPLYING PRESSURE T0
SHOE BOTTOMS
Sidney J. Finn, Beverly, Mass., assignor to United
Shoe Machinery Corporation, Paterson, N. J., a
corporation of New Jersey
Application April 7, 1937, Serial No. 135,512
36 Claims. (Cl. 152-33)
This> invention relates to machines for apply
ing pressure to shoe bottoms and is herein il
lustrated -as embodied in a cement sole attaching
machine of the type disclosed‘in Letters Patent of
5` the.~ United States No. 2,047,185, granted July lé.,
1936, upon an application ñled in the name of
Milton H. Ballard et al.
The-machine of the patent mentioned is pro
vided withra plurality of‘pads for receiving soles
and shoes, these pads being arranged to be pre
sented successively at an operating station. As
sociated witheach pad are sole and shoe posi
tioning members or gages for relatively locating
the soles and shoes on the pad, these sole and
15 shoe gagesbeing moved yieldingly toward a sole
on the pad and the sole gages, after finding and
contacting with the edge face of the sole, becom
ing locked automatically to hold in position the
shoe gages which will properly locate the shoe
20 with respect to the sole when the shoe is placed
thereon. Pressure is then applied to the shoe to
press the sole and shoe against the pad, the pres
sure being provided by ñuid pressure operated
mechanism which forces the sole and shoe down
5 wardly some distance into the pad when the full
pressure has been applied. It will be seen that if
the gages remain in locked engagement with the
sole and shoe as these members sink into the pad
there may be danger of some of the gages soar
30 ring the upper of the shoe as it moves downwardly
past the gages or danger of the gages indenting
the shoe during the remainder of the pressure
applying operation.
It is an object of the present invention to pre
vent any damage to» the shoe by the sole and
shoe positioning gages during the pressure ap
plying operation.
With this end in view, afeature of the inven
tion consists in the provision of improved means
40 for releasing or unlocking the sole and shoe gages
during the application of pressure to the sole and
shoe and for withdrawing these gages from oper
ative engagement with the sole and shoe. As
herein illustrated, the gage releasing and with
45 drawing means is fluid-pressure-controlled and is
connected with the same source of fluid pressure
supply as the iiuid pressure operatedmechanism for
applying pressure to the shoe. The releasing and
withdrawing means is preferably arranged to op
50 erate after suilicient pressure has been applied to
the sole and shoe by the building> up of a prede
termined pressurein the pressure system of the
machine to clamp the sole‘and shoe on the pad
and thereby to` insure against relative displace
55: ment of the sole and shoe after the gages have
been withdrawn but before the full pressure has
been applied.
The gage releasing and withdrawing means, as
herein illustrated, includes a iiuid-pressure-oper
ated. plunger constructed and arranged through ' Ul
a pivoted member to actuate gage operating and
controlling mechanism associated with each pad
and thereby to release and positively withdraw
or retract all the gages simultaneously to their
out'er or inoperative positions. In order that this
action may not occur until after a predetermined
pressure has been applied to the sole and shoe,
the plunger is arranged to operate against a
spring the resistance of which may be varied as
desired for operating, for example, on men’s,
women’s or children’s shoes.
In accordance with another feature of the in
vention'means is provided for latching the gages
on each pad box in their withdrawn or inoper
ative positions until the pressure applying oper- â
ation has been completed, thereby insuring
against the return of the gages into engagement
“
with the sole and shoe before the latter have
been removed from the pad. As illustrated, the
latching means is adapted to operate automati
cally when the gages have been moved into their
outermost or retracted positions Further means,
25
operated by return of the pressure applying
mechanism of the machine to inoperative posi
tion, is provided for releasing the latch just be
fore the pad with which it is associated re-enters
the operating station at the completion of the
pressure applying operation. This latch releas
ing means is also arranged to maintain the latch
in an inoperative position until the gages have
positioned another sole and' shoe on the pad and
the pressure applying mechanism has'been moved
into operative position. At this time the latch
is permitted to return to an operative position
so thatV when a predetermined pressure has been 40
applied to the sole and shoe on the pad, and the
gages are released and withdrawn by the mech
anism above referred to, the latch will act auto
matically to lock the gages in their withdrawn
positions,
45
Although the latch is released automatically be
fore the pad is fully. located in the operating sta
tion, so that the gages are then under the con
trol of their actuating mechanism, the construc
tion and arrangement is such that the usual gage 50
retracting mechanism with which the machine is
provided comes into play to prevent the gages
from moving inwardly toward the sole and shoe
even though the gages are not locked in their
Withdrawn positions.

40 positioning gages is illustrated herein as em
bodied in a machine of the type disclosed in the
Ballard et al. patent referred to above, the
drawings and description being limited to those
portions of the machine which are directly con
45 cerned with the invention.
For a more com
plete description of the portions of the machine
not illustrated or described herein, reference may
be had to the patent mentioned.
The cement sole attaching or laying machine
50 comprises a base or column I0 upon which is
mounted for rotation about a vertical axis a tur
ret I2 which carries a plurality of pad boxes
I4 arranged to be presented in succession at an
operating station located at the front of the
55 machine. Each pad box I4 is provided with a
yielding pad I6 adapted to receive a sole A and a
shoe B (Figs. 2 and 3). The sole A is positioned
on the pad by an operator and it is held in posi
tion thereon by sole and shoe positioning mech
60 anism best illustrated in Figs. 3 and 4, this mech
anism functioning also to locate the shoe rela
tively to the sole.
The sole and shoe positioning mechanism com
prises gage arms I8 for operating on the sole and
85 shoe in the vicinity of the ball line and gage
arms 20 for engaging the sole and shoe approxi
mately at the tip line, the gage arms 28 being ar
ranged in crossed relation to each other, as
shown in Fig. 3. The gage arms IB carry at their
70 forward ends sole gages 22 and shoe gages 24,
the latter being adjustable relatively to the sole
gages by eccentric adjusting mechanisms pro
vided with handles 25. The gage arms 20 for
the tip line are likewise provided with sole gages
28 and shoe gages 3D which are relatively adjust
The gage arms I8 and 20 are moved about their
thereby from engagement with the sole and shoe
and to move them into their outer or inoperative
positions by swinging movement of the rocker
member 54 toward the left, as viewed in Fig. 3, 40
this rocker member, as described in the patent
referred to, carrying projections 56 each a1“
ranged to engage a roll on a gage arm and to
move the gages into their inoperative position
simultaneously. Movement of the rocker mem
ber 54 in the direction indicated to withdraw the
gages operates first, however, to release the lock
ing bolt 50 and thereafter to move the gages into
their withdrawn positions against the action of
their operating springs.
50
The rocker member 54 is actuated by a sub
stantially horizontal link 58 held in this position
by a stationary guide member 5i) provided with a
slot which engages a pin 82 mounted in the right
hand end of the link, as viewed in Fig. 3. 'I‘he 55
pin 62 carries a roll 64 which rides in a slot 66
formed in an upright arm 88 of a bell crank lever
pivoted to the turret on a shaft 'i2 and having a
lower, substantially horizontal arm 'lil (Figs. 1
and 6). Movement of the bell crank lever 88 in 60
a counterclockwise direction, as Viewed in Figs.
l and 6, actuates the rocker member 54 to re
lease the locking bolt 50 and move the gage arms
I8 and 2l] against their springs in a direction to
withdraw the gages from the shoe and sole, and 65
movement of the bell crank lever in the opposite
or clockwise direction permits the gages to move
inwardly toward a sole on the pad under the
action of their springs 44, 46.
A spring 14, con
nected between the arm 68 and a pin 'I6 on the
70
turret, tends normally to swing the bell crank
lever in a clockwise direction into a position
where the gages will be contacting with a sole
on the pad, the movement of the bell crank lever 75
:2,117,306`
being limited by a stop-screw 18 arranged to en
gage theturret I2'.

The mechanism with which the machineispro
vided at-the operating station for actuating the
bellcrank lever 68 and thereby operating the sole
and shoe positioning gages comprises a stationary
cam 80 fastened to the upper end of astandard
82` and provided with an inclined surface 84 ar
ranged to engage a roll 86 carried by a shouldered
10 screw 8T extending through the horizontal arm
'ißlof the bell crank lever 63, As each pad box
moves _into the operating station from left to
right, as viewed in Fig. 1, the lever €581 associated
with that pad` box4 is, in the machine of the pat»
15. entreferred to, swung in a counterclockwise di»
reotion bythe cam 80 to release the gage locking
bolt and withdraw the gages to inoperative posi
tion through thel operation of the rocker mem
ber 54'., When the pad box comesto a stop at the
operating station the roll 86 would ordinarily be
resting on a ledge member 88‘ (Figs. l and 6)
forming a continuation of the. stationary` cam 8G,
this> ledge member being carried. by,- a lever 95
pivoted at 92 on the stationary cam 8U.
In the machine disclosedf in the patent men
tioned, when it is desired to swing the bell crank
lever 68 of the pad box at the operating station
in clockwise direction (as viewed in Figs. 1 and
6) and thereby operate the rocker member 54
30 to permit the gages to be moved inwardly by
their springs into contact with the edge face of
the sole; the lever 90 and the ledge member 88
carried thereby are moved downwardly by a
trea-dle 94 (Fig. 1) connected` to the lever 9D at
35 95» by a treadle rod 96 working against a treadle
elevating spring 98. As the parts are shown in
Fig. 6, the ledge member 83 has been moved
downwardly by depression oi‘ the treadle 94 but,
because of other mechanism which forms a part
The machine of the patent mentioned is also
provided with hydraulically operated pressure
applying mechanism` for pressing the shoe B
against the sole A after they have been properly
positioned relatively to each other on the pad by
the gage‘mechanism, the‘shoe and sole, of course,
having been previously treated with cement
whereby the sole is to become attached either
temporarily or permanently to- the shoe bottom.
Before proceeding to describe the mechanism oi I0
the present invention for automatically with~
drawing .and latching the sole and shoe gages in
inoperative position, a brief description of the
hydraulic or fluid pressure operated mechanism
for pressing the sole and shoe against the pad 15
will be given.
Each pad box on the turret is provided with
pressure applying mechanism comprising a cyl
inder HU (Fig. 2) having mounted therein a
piston H2 carrying at its upper end a pivoted 20
lever lili the opposite ends of which are disposed
under levers H5 pivoted at H8 to a swinging
frame member iZil, the latter being secured by
a set screw 52E to a shaft 522 rotatably mounted
in the turret. The swinging frame member I2@ 25
is arranged for swinging movement from `a rear
wardly inclined inoperative position into a sub
stantially vertical operative position over the pad '
box by a handle iîllê. One of the two pivotedlevers H6 carries a block i2ë for engaging the 30
top of a last in the shoe on the pad and the other
lever itâ carries a toe rest £28 for engaging the
toe portion of the shoe. Upward movement of
the piston H2 due to the introduction of iiuid
such as oil under pressure into the cylinder 35
through a pipe iSil, causes the levers Hä to be
swung in a direction to bring the abutments §26.
i28 into engagement, respectively, with the last
and shoe so that the sole and shoe will be forced
has not been swung in a clockwise direction by
downwardly against the pad, It will be seen 40
from the foregoing that, if the sole .and shoe
the spring 1d to bring the stop screw 'I8 against
thel turret'and, accordingly, the sole and shoe
main in locked position against the sole and shoe
40 of the present invention, the bell crank lever 63
positioning gages are still maintained in their
45 withdrawn or retracted positions.
In the machine of the patent referred to,
after the sole »gages have been permitted to come
into. engagement with a sole on the pad` in the
manner described, it is necessary to retain the
50 lever` Sil. and the ledge member 88 in a lowered
position so that the gages will remain locked
against the sole. For this` purpose a latch ißâi
is provided, the latch being pivoted on a pin §02
mounted in the stationary cam 80 and being
55 adapted to snap over a shoulder on the lever Si!
under the action of a spring HM. connected to
the lever 90 at |05 and tending constantly to urge
the latch in a counterclockwise direction about
its pivot |02. After the sole and shoe have been
60 properly positioned on the pad Idand have been
pressed against the pad by the pressure applying mechanism, the turret rotating mechanism
of the machine is operated to cause the pad box
and‘ the gage actuating mechanism associated
" therewith to move out of the operating station.
Vifhen this occurs a roll H35 on the center 'i2
ridesalong an inclined cam surface lü‘lî on the
lever 9B and engages an upward projection H35
on the latch |00. This disconnects the latch
70 from the lever S01 and the latter is permitted to
return gradually to its original elevated position
by theinclination of the cam surface iii?. As
stated above, the mechanism just described is
provided` in the machine of the BallardY et al.
75 patent and. isv fully disclosed therein.

as the latter are moved downwardly against the
pad, some of the gages may Contact with the
f4.5
shoe in such a manner as to mar or otherwise
injure the shoe upper. It is desirable, therefore,
after the gages have operatet to position the sole
and shoe relatively to each other on the pad, and
the pressure applying mechanism has been actu to
ated suihciently to clamp the sole and shoe
against the pad so that they will be held there»
after in proper relative positions, that the locked
gages should be released and withdrawn from en*
gagement with the sole and shoe and maintained .5.5
in their withdrawn positions for the remainder oí
the pressure applying operation, this action pref
erably taking place after a predetermined pressure
of, for example, fifty pounds to the square inch
has been built up in the huid pressure system 6.0
of the machine so that suihcient pressure will

these been
members
.applied
against
to the
thesole
padand
andshoe
thereby
to pre
vent any relative displacement thereof. The
mechanism for accomplishing this result, which 65
forms the subject-matter of the present inven
tion, will .now be described.
As indicated above, the bell crank lever 6B
in the present construction, has not been swung
in a clockwise direction, as viewed in Fig.
until
the stop 18 is against the turret l2, even though
the ledge member 88 is illustrated as having been
lowered by the depression of the treadle 34` and,
consequently, the gages are not contacting with
the‘sole and shoe. The‘bell crank lever 68de held 7,6
4
2,117,306
in the position shown in Fig. 6 by a latch | 32
loosely pivoted on the upright arm 68 of the bell
crank lever about midway of its length on a
screw |34. In order that the latch |32 will always
be free on the screw |34, it is actually pivoted on
a cylindrical projection |36 (Fig. 5) formed on a
clamping nut |38, the nut fastening the screw in
the arm 68 but permitting the latch |32 to pivot
freely about its cylindrical portion.
10
Secured by a screw |46 (Figs. 1 and 8) to the
under side of the turret I2 is a stationary angle
plate |42 having an inwardly projecting portion
arranged to be engaged by a notch in the lower
edge of the latch |32. IThe angle plate |42 may
15 be adjusted lengthwise of the pad box about the
screw |40 and maintained in adjusted position by
a stop screw |44 (Figs. 6 and 8), the inner end of
which engages a portion ofthe turret |2. The
latch |32 is caused to hook over the plate |42 by
swinging movement of the bell crank lever 68 in
a counterclockwise direction after the sole and
shoe have been properly positioned on the pad
and a predetermined pressure has been applied
thereto. The latch remains hooked over the plate
25 to hold the bell crank lever in the position shown
in Fig. 6 and thegages withdrawn during the ro
tation of the turret for the greater part of one
revolution or just prior to the return of the pad
box under consideration to the operating station
30 at which time the latch is automatically released,
in a manner to be hereinafter described, so that
the gages will not be locked in their withdrawn
position. The gages will not, however, be moved
inwardly toward the sole and shoe by their springs
35 at this time because the release of the latch |32
occurs at such a point in the cycle of the machine
that the roll 86 on the horizontal arm 18A of the
bell crank lever will have engaged the inclined
surface 84 on the stationary cam 88 to retain the
40 bell crank lever in substantially the same posi
tion it occupied when latched, although the latch
is then raised up away from the plate |42 and is
held in such position.
’ Before proceeding to describe the fluid pressure
45 operated mechanism of the invention for swing
ing the bell crank lever 68 in a counterclockwise
direction, as viewed in Fig. 6, to withdraw the
gages and for permittingthe latch |32 to hook
over the plate |42 to lock the gages in this with
50 drawn position, a description will be given of the
mechanism for automatically releasing the latch
|32 just before the pad box enters the operating
station and for maintaining the latch in an inop
erative position until the sole and shoe have been
55 relatively positioned on the pad and a predeter
mined pressure has been applied thereto.
The swinging frame member |28 (Fig. 2) is
swung forwardly into operative position over the
pad by the operator, as stated, but is caused to
60 return to a rearwardly inclined inoperative posi
tion automatically as the pad box with which it
is associated is about to enter the operating sta
tion. The mechanism for effecting the automatic
movement of the swinging frame |26 into its inop
erative position, as disclosed in the Ballard et al.
patent, comprises a segmental member |46 (Figs.
2 and 9) loosely mounted on the rotatable shaft
|22 which forms the pivot for the swinging frame
|20, the member |46 engaging a spring |48 pro
70 jecting from a lug 15D on the lower portion of
the swinging frame. Movement of the segmental
member |46 in a clockwise direction against the
spring |48 causes the swinging frame to swing
rearwardly into its inoperative position, this po
75 sition being determined by a stop block |52 on
the cylinder ||0 which is engaged by a collar |54
fastened by a set screw |56 to a sliding rod |58
arranged to slide through the block |52 and piv
otally connected at its forward end by a pin |60
to the swinging frame. The operative or vertical 5
position of the swinging frame |26 is determined
by a fiber collar |62 secured by lock nuts |64 on
the inner end of the sliding rod |58. Since the
swinging frame is fixed to the shaft |22 the lat
ter, of course, turns in its bearings as the swing 10
ing frame moves into and out of operative posi
tion.
The segmental member |46 is caused to rotate
in a clockwise direction by a roll |66 (Figs. l, 6
and 9) arranged to engage the inclined surface 15
84 of the stationary cam 86 as the pad box moves
into the operating station, this roll being carried
by a member |68 pivoted to the turret on a pin
|10 and pivotally connected to the segmental
member |46 by a pin |12. As the roll |66 rides 20
up the inclined surface of the cam 8|) the member
|68 is swung about its pivot |18 to elevate the
pin |12 and to force the segmental member
against the spring |48 mounted in the projection
or lug |58, thereby automatically returning the 2,5
swinging frame member to its rearwardly inclined
inoperative position.
The opposite end of the shaft |22 has secured
to it by a set screw |14 a forwardly extending arm
|16 (Figs. 6 and 8) having adjustably secured 30
thereto by slot and screw connections |18 an ex
tension piece |88 the upper edge face of which is
curved in a manner to engage a relatively long
flat surface on the lower edge face of the latch | 32
and to raise this latch upwardly about its pivot 35
|34 away from engagement with the ñxed plate
|42. As the swinging frame |28 is swung into its
rearwardly inclined position by operation of the
mechanism just described, the shaft |22 turns
to elevate the arm |16, |88 and cause it to raise 40
the end of the latch away from the plate |42,
thereby releasing the bell crank lever 63 so that
it can be swung about its pivot 12 in a clockwise
direction, as viewed in Fig. 6, by the spring 14 to
permit the sole and shoe position gages to move 45
inwardly under their operating springs into en
gagement with the sole A on the pad. Since the
swinging frame member i2@ is swung automati
cally into this inoperative position as the pad box
associated therewith is entering the operating 50
station, the latch will be maintained in an ele
vated position at that time by the member |80
and the roll 86 on the arm 16 will engage the cam
surface 84 on the stationary cam and come to
rest on the ledge member 88. Subsequent de 55
pression of the treadle 94 lowers the ledge member
88 and permits the arm 68 of the bell crank lever
to swing to the right, as viewed in Figs. l and 6,
thereby permitting the sole gages to move yield
ingly into engagement with the sole on the pad 60
and to become locked in such position. After the
shoe has been positioned on the sole and a part
of the sole attaching pressure has been applied,
the bell crank lever 68 is caused to swing auto
matically in a counterclockwise direction, by 65
mechanism next to be described, so that the latch
|32 will hook over the fixed plate |42 and lock
the gages in their open or withdrawn position, the
member |86 having been lowered by turning of
the shaft |22 when the swinging frame member 70
was moved into its Vertical position by the oper
ator to apply pressure to the sole and shoe and
thus` permitting the elongated ñat surface on the
latch | 32 to ride on the upper edge face of the
plate |42. Accordingly, further movement of the 75
J5
.2,117,308
:latch toward the left, as viewed in Fig. `6, by the
mechanism vnow to be described, will Vcause the
Alatch to hook over the plate |42 »and lock the
`gages in their withdrawn position, this mechanism
being best illustrated in `Figs. 2, 6 and 9.
The machine .is provided adjacent to the oper
ating station with a stationarypost |82 (Fig. 2)
to which is secured a bracket |84. Secured to this
bracket by screws |86 Vis an upstanding member
10 |88 having an upper portion |90 in the form of a
'substantially *horizontal cylinder having a bore
of .substantial -diameter therein. Mounted for
sliding movement in the bore in the cylinder |90
`is a plunger |92 having a slot |04 extending
>lengthwise thereof and through which a pin |96
passes, the pin serving to limit lengthwise slid
ing `movement of the plunger in the cylinder. A
pipe |98 `is threaded ’into the lower side of the
cylinder in an opening which communicates with
the bore therein. 'I'he pipe |98 extends down
'wardly‘and is connected at its lower end (Fig. l)
tothe hydraulic pressure power system of the
machine. This ñuid pressure system, as fully de
scribed in theBallard et al. patent, is provided
with a series‘of valves throughthe operation of
which Yin `a particular manner, by mechanism not
'disclosed herein, the free circulation “of fluid such
las‘oil through the pressure system isstopped. For
the purpose of the present disclosure it is sufficient
IBO to state that this free circulation of oil through
the pressure system is stopped by the depression
Aof a treadle2200 (Fig. 1) which ‘lowers a rod 202
having a collar 204 (Fig. 2) `thereon and between
which and a washer'206 is a compression spring
208. The washer `206 rests on the `forked for
ward end of `a lever `2|0 pivoted at »2|2 and having an inner arm 2|3 connected at its inner end
`by a link `2|!! to an arm »2|5 forming apart of a
pressure inducing valve 2 I8 which is provided on
'210 `the machine for controlling the ñuid pressure sys
tem. When thepressure .inducing valve 2|8 `is
open the oil circulates freely through the system
and when the valve is closed» fluid pressure is built
up in the system and Iin the pipe V|30 to elevate‘the
piston | I2 »andïapply pressure to the soleland shoe,
the `fluid passing through `a three-way valve
‘mechanism 220 (Fig. l) .before entering the cylin
der 'I t8. The amount of pressure which may be
built up in the :system may be as high `as 300
-pounds per square inch'if such a pressure is neces
’sary or desirable in attaching -a` sole to a Yshoe
bottom. The valve 2|8 is normally held closed
by a spring `222 anddepression of the treadle 200
`raises the arm2 | 6 to open ~the valve and cause the
ci il fluid pressure mechanism Ito operate.
Returning now to the gage `withdrawing -mech
«anisnn illustrated in Fig. 9, the cylinder |90 `has
`extending upwardly `therefrom >a pair of arms
224 (Figs. 'ï 'and 9) in which 'is rotatably mounted
am `a vpin 226 havingsecured thereto by a set screw
`228 a member l23|). The -member 230 has a down
wardly projecting lug 232 »located opposite the for
ward end of the `plunger' |92 Aand a screw 234 is
threadedlthrough the lug` so that its Yinner end
contacts with the plunger. The screw 234 `is held
against the plunger î|92 by a tension spring 23‘5
extending through an opening‘231 in the member
280 and connected theretoby a pint238,lthe spring
`being connected `at its other end to the cylinder
in the system and in the -cylinder |90 before -the
>plunger will start to move to `swing the member
230 upwardly about the center 226.
The `member 230 has an upwardly facing `pro
jection 244 thereon having `a `somewhat convex
top surface. The projection 244 is .arranged to
underlie a circular end portion 246 of a -lever
`248, best shown in Fig. '7, and secured to the
horizontal arm 10 of the bell crank lever~68 -by the
shouldered screw 8T which carries .the lroll ‘88. 10
The opposite or left-hand end of vthe lever24’8,
as viewed in Figs/6 and 7, is ‘bifurcated and
straddles the shaft '|2 so that the lever will lswing
about the shaft with thearm 10.
As indicated above, when the pressure built> up
in the cylinder `|90 overcomes the resistance `of
`the spring 236, the piston |92 moves forwardly for
tothe left, as viewed in Fig. 9, and, as thepressure
in the cylinder increases, the plunger iforces `the
member -230 upwardly about vthe pivot until the
projection 244 engages the portion 249 ~of `the
lever 248 therebyswinging this ylever and the arm
10 of the bell crank lever '.68 (to~ whichit isvcon
nected) upwardly or in La counterclockwise `direc
tion about the pivot `'|2. -This action of thefbell
crank lever operates 'the rocker member `54`to
unlock and withdraw the fsole and shoe'positioning
gages from engagement `with the sole :and shoe
and to return them to their outermost or inopera
tive position illustrated in Fig. 4. The latch
|32, which‘has been permitted by the lowering
of the member |80 to ride on the plate |42, drops
`into latched engagement with `the :plate when the
gages are fully retracted, thereby `locking the
gages in Athis position. In order that oil which
may leak from the ‘bore of the cylinder `|90
through the reciprocative‘movement ‘of the‘plung
er |92 will not run over the outside ïof the -ma
chine or reduce the amount of oil in fthe ‘.fiuid
pressure system, the cylinder |90 is provided-with ‘
a drain pan or lip 252 which is >arranged to catch
any oil which leaks "from the cylinder. Apipe »254
is connected to the portion l252 to carry the `oil
back into the ñuid pressure system of the ma
chine.

Although the operation of the mechanism
which ‘forms the subject-matter of the present
invention will be apparent from the foregoing de
scription, a summary thereof will be here given
for'the purpose of clearness.
When a pad box which is 'to receive a sole and
shoe is located at the operating station, the gage
arms I8 and i729 carrying the sole and` shoe vpositioning gages are in their outer or retracted ’posi
tion, the gage mechanism being >held in this posi« l
tion because `the roll v86 is resting on the »ledge
member 88 which, at this time, is in `its elevated
position.
The :gages are free, however, to move
inwardly toward the sole .and shoe, through the
operation of their respective springs, because the
swinging frame member |20 is located inits rear
wardly‘inclined inoperative position so that the
.member or‘arm |80 is engaging the latch |32 and
holding it above the fixed plate |42. The‘opera
Vtor places «a `sole on the pad and deprcsses thegage treadle94 to lower Vthe Vledge memberl88 and
`permitthe sole gages 22, 28 yieldingly to find the
`edge face of the sole, after which the :gages auto
matically lock.
rThe operator then places the
|90 by a hook 249 threadedinto an vupwardly pro- ' shoe between the locked `shoe gages, which posi
`jecting lug 242 “on Vthe cylinder. r‘I‘he tension or
resistance 'or thev spring '23E may `be varied by
meanssof a nut `on the hook 240, `and this tension
is preferably fsuch 'that it will 'be overcome by
no
about ’fifty pounds’ ïfluid `pressure‘per vsquare inch
tion it relatively to the sole, and 'he `swings the
swinging frame member `|20 forwardly by the
handle i |24 into its substantially vertical opera
tive position, as shown in Fig. 2, this action turn
ing the shaft |22 `and swinging the `member |80“,
70

2,117,306
downwardly away from the latch |32, thus per
mitting the latch to descend so that its straight
edge portion at the left of the notch in the latch,
as viewed in Fig. 6, rides on the upper edge of the
plate E42 but the latch does not hook over the
plate because the bell crank lever 68 has been
swung too far in a clockwise direction, as viewed
io
in that figure, to permit the notch in the latch
to engage the plate.
The operator then depresses the pressure ap
plying treadle 26E] which operates the valve ZIS
and sends fluid under pressure into the cylinder
IIIJ to elevate the piston H2 and to apply hy
draulic pressure to the sole and shoe. As the
15 pressure on the sole and shoe increases the ñuid
under pressure which is simultaneously entering
the cylinder |90 through the pipe |98 is building
up the same pressure in the cylinder. Accord
ingly, if the spring 235 is set to withstand a pres
sure of fifty pounds per square inch in the sys
tem, when this predetermined pressure acting on
the piston H2 has been applied to the sole and
shoe the spring will yield. As the plunger moves
forwardly under the increasing pressure in the
25 cylinder |99, the member 239 will be swung up
wardly to elevate the lever 248 and arm li) and
thus rotate the bell crank lever 68 in a counter
clockwise direction about its pivot l2 until the
notch on the latch |32 drops over the stationary
30 plate |42, this movement, of course, operating the
rocker member 54 to unlock the sole and shoe
gage arms and, through the lugs on said rocker
member, to force these arms into their outer or
retracted
positions
against
their
operating
35 springs. Thus it will be seen that the sole and
shoe gages are released, withdrawn and latched
in inoperative positions automatically by fluid
pressure operated mechanism when a predeter
mined pressure has been applied to the sole and
shoe.
The gages remain latched in their inoperative
position as the pressure on the sole and shoe in
creases to the desired amount, so that there is
no danger of the gages scarring the shoe as it
45 sinks into the pad.
The operator then actuates
the turret rotating mechanism and the pad box
moves out of the operating station and inter
mittently around the machine as the other pad
boxes are loaded in the manner described, the
gages remaining latched in inoperative position
all the while.
As the pad box under considera
tion approaches the operating station, the roll
|66 rides up on the stationary cam Bü and auto
matically swings the swinging frame member |23
to its rearwardly inclined position through the
operation of the segmental member |45, the pres
sure on the sole and shoe having, of course, been
relieved by other mechanism on the machine be
fore the swinging frame member is swung rear
60 wardly. Rearward movement of the swinging
frame |29 turns the shaft |22 and actuates the
member |80 to elevate the latch |32 and hold it
out of engagement with the plate |42. At the
same time the roll 85 has moved far enough along
65 the inclined surface 84.> of the stationary cam 8S
to prevent the released gages from returning un
der the action of their springs into engagement
with the sole and shoe. Accordingly, although
the gages are not locked at this time and are free
70 to be moved into operative position by their
springs, if permitted, they are nevertheless re
tained in their outer or retracted positions by rea
son oi the engagement of the roll 86 with the
cam 8l! and the ledge 88. After the shoe, with
75 its sole attached thereto, has been removed from
the pad the operator places another sole on the
pad and repeats the operations described above.

drawn position until they are operated to posi
40 tion another sole and shoe on the pad.
34. In a machine for applying pressure to shoe
bottoms, the combination of a plurality of pads
for receiving soles and shoes, said pads being ar
ranged to be presented in turn at an operating sta
45 tion, gages associated with each pad for relatively
positioning a sole and shoe thereon when the pad
is located at the operating station, means in
cluding a pivoted lever and springs associated
with each pad for operating said gages, treadle
operated means at the operating station for ac
60 tuating the gage operating means, means movable
toward and away from each pad at the operating
station for pressing the sole and shoe against each
pad thereby applying pressure to the sole and
shoe, fluid-preSsure-operated means for with
55
drawing the gages from operative engagement
with the sole and shoe on said pad after a prede
termined pressure has been applied thereto,
9
means for automatically latching the gages of the
pad in a withdrawn position until said pad is
again ready to enter the operating station, means
operated by movement of the pressing means
away from said pad for automatically unlatching ril
the gages after the pressure applying operation is
completed, and means at the operating station
for preventing the gages from returning to op
erative position until said treadle operated means
is again operated.
35. In a machine for applying pressure to shoe
bottoms, the combination of a plurality of sole
receiving pads arranged to be presented in turn
at an operating station, gages associated with
each pad for relatively positioning a sole and
shoe thereon, a member at the operating station
for pressing the sole and shoe against each pad
thereby applying pressure to the sole and shoe,
said member being arranged to swing toward and
from the pad into and out of operative position, 20
means associated with each pad for operating
the gages, means for automatically withdrawing
the gages of the pad at the operating station
after a predetermined pressure has been applied
to the sole and shoe thereon, a latch carried by 25
each gage operating means for maintaining the
gages in a withdrawn position until the pressing
operation is completed, and means movable to
ward and from the pad with said pressing mem
ber for automatically releasing the latch when 30
the swinging member moves away from position
over the pad.
