Pincus Brauner, Haverhill, Mass.
Application December 11, 1934, Serial No. 756,965
16 Claims. (Cl. 12-37)
This invention relates to machines for use in
manufacturing shoes and particularly to ma
chines having a number of in?atable shoe presses
or jacks each adapted to hold a sole ?rmly against
5 a shoe bottom while the cement sets.
The ma
chine illustrated is intended primarily for use in
the manufacture of shoes in which cement alone
is relied upon to permanently attach the outer
sole to a shoe.
lo
When cement is employed to permanently se
cure the sole to a shoe it is important that the
adhesive covered portions of the sole be ?rmly
pressed against the bottom of the shoe, and if
a cement which does not grip immediately is used
1.7 it is important that the sole be held ?rmly in
place throughout the one or more minutes re
quired for the cement to set.
It has been proposed heretofore to provide shoe
presses or jacks having an in?atable pad for
m pressing the sole ?rmly against the bottom of a
“ shoe, and in order to speed up production it has
been suggested heretofore to provide a rotating
wheel or table having a number of in?atable
jacks and provided with valve means at the hub
25 of the wheel adapted to be controlled by the ro
tation of the wheel to in?ate and de?ate the
jacks, so that each jack will be held in?ated as
the wheel rotates throughout the greater part
of a complete circle. Di?iculty has been ex
.30 perienced heretofore however in providing a ro
tating valve at the hub of the wheel which will
not leak under the relatively high pressure em
ployed to in?ate the pads, and which will permit
the wheel to rotate freely. This di?iculty in se
Ct, cal curing a tight valve has been largely due to the
fact that when the non-rotating part of the
valve is formed rigid or integral with the wheel
supporting axle any slight play or inaccuracy
in the wheel bearing tends to disturb the seating
in of the valve parts and causes leakage, and if the
valve is tightened to prevent such leakage the
increased friction makes the wheel hard to turn.
One important feature of the present inven
tion therefore resides in a valve which overcomes
4,; this di?iculty and more particularly in a, con
struction whereby the non-rotating part of the
valve is ?oatingly connected to the ?xed wheel
axle and is held seated in the portion of the valve
that rotates with the wheel without carrying any
50 load, and as a result a tight valve seat is secured
which is not disturbed by the rotation of the
Wheel or inaccuracies in the wheel bearing.
The time required to remove a shoe with the
sole attached from a jack and insert another
55 shoe is only a small fraction of the time required
for the cement commonly used to’ set, so that a
skilled operator can jack and unjack a number
of shoes during the period that a shoe should
be held in a jack while the cement sets. It has
therefore been proposed heretofore to provide
the jack supporting wheel with a relatively large
number of jacks, but this has resulted in the
use of a large unwieldy wheel.
5
1
Another important feature of the invention
therefore resides, in a sole cementing machine 01' 10
the rotating wheel type but which is so con
structed that a relatively large number of jacks
can be mounted upon a much smaller and lighter
wheel than in the construction proposed hereto
fore, and in which jacks extend radially out
wardly beyond the periphery of the wheel and
5
frontwardly from the plane of the wheel so that
the shoes can be more readily placed in and re
moved from the jacks.
1
A further feature resides in pedal controlled 20
means that cooperates with the jack supporting
wheel whereby when a jack is in position to be
controlled from the operating station it may
be either in?ated or de?ated at the will of the
operator by operating one or the other of apair 5
of foot pedals. ‘This is important because it is
necessary that the sole be accurately applied. to
the shoe preparatory to cementing it in place
and this foot controlled means enables the opera
tor to quickly in?ate the jack While the shoe and 30
sole are held in place, and to quickly de?ate the
jack in case the shoe parts are not properly posi
tioned in the jack. Furthermore as a result of
these foot pedals for controlling the in?ation of
a jack at the operating station, shoes may be
placed in the jacks and removed therefrom while
the wheel rotates continuously at a uniform
speed.
Still a further feature of the invention resides 40
in the construction of the wheel for supporting
the jacks whereby the pipes for in?ating the
jacks are concealed in the spokes and cast parts
of the wheel where they are protected and out
of the way, and another feature resides in novel 45
means for completing the pipe connections be
tween a jack and the valve at the hub of the
wheel as the jack is secured to the wheel;
Other features of the invention and novel com
bination of parts in addition to the above will
be hereinafter described in connection with the
accompanying drawings which illustrate one
good, practical form of the invention.

In the embodiment of the invention illustrated
in the drawings the shoe presses or jacks ID
are provided with supporting brackets H adapt
ed to be secured by bolts 12 to bosses I3 formed
on the rim' I4 of a jack supporting wheel. This
wheel is shown as having ?ve spokes l5 extend

vl4. The wheel and jacks are so constructed that
the jacks are supported by the bracket‘ ll so

journaled in the casing I8. The shaft 28 is driven 10
through the'bevel gears 29 from a vertical shaft
30. The shaft 39 is driven by an electric motor
3| and the reducing gears within the gear casing

project frontwardly a substantial distance‘ from
the plane of the wheel. This arrangement per
mits a relatively large number of jacks (thirty in
the present case) to be carried by awheel that
V's less than four feet in diameter, and positions
the jacks frontwardly of the'plane of the wheel
far enough to permit the machine operator en
gaged in‘ placing the shoes in the jacks to look
downward upon the shoe from a position near
s; ‘*5 the hub of the wheel to see if the sole of the
shoe is correctly held against the bottom of the
shoe when the shoe supporting pad or bag I1 is
in?ated.
‘ The wheel which carries the jacks is supported
in the construction shown to rotate in a verti
cal plane by a hollow column or casing l8 adapt
ed to support the wheel at such a height from
the floor that when a jack l0 lies directly below
the axis of the wheel asshown in Fig. 2 itwill
' be just high enough from the floor to be most
motor by the conductors 34.
The machine of the present invention is de
signed more particularly for use in cementing the
outer soles permanently to shoes when a cement
is used which does not grip, immediately but 20
requires an intervalrof time for the cement to
set, and by employing a wheel carrying a large
number of jacks, each jack may be kept in?ated
while itirotates through the greaterpart of a
complete circle and the other jacks of the wheel
have the shoes therein changed. _.
I
One important feature of the present inven
tion'resides in the‘ means for controlling the in
?ation and de?ation of the bags I‘! of the vari
ous jacks, as the wheel rotates,_and the means T
shown to'this end willnow be described. The
wheel has cast or otherwise secured in its front
fa'hce about the axis of rotation a ring 35 which
may be formed of steel and this ring is pro
vided with pipe receiving holes adapted to re
ceive the jack in?ating pipes 36 one for each of
the thirty jacks. The ends of these pipes'may be
welded or otherwise secured in the ring 35 to
provide air tight‘joints therebetween and the
outer face of the ring may be ground to provide 40
a. smooth true surface.
To the outer face of the ring 35 is secured the
ring-like valve member 31 which is secured to the
ring by the bolts 38, and a gasket 39 is provided
between the members 35 and 31 to prevent leak
age of the compressed air from between them.
The valve memberv 31 is bored or otherwise pro
vided with they air passages 40 which align with
the ends of the pipes 36 in the ring 35; The pas-v
sages 40 communicate with ports“ and 42 ar

2,076,697
The pipe connections so far described serve to
supply compressed air from the outer valve mem
ber 31 to the bags I‘! of the various jacks, and
the means for supplying compressed air to and
exhausting the ports of the valve member 31
will now be described. Compressed air from any
suitable source of supply (not shown) is supplied
by a pipe 49 to a bore 59 formed longitudinally
of the ?xed axle 20, and secured to the opposite
10 end of this bore by the coupling 5| is a ?exible
pipe 52. Within the rotating valve member 31
is seated the non-rotating valve member 53 and
compressed air is supplied to the ports 54 and
55 and connecting conduit 56 of the valve mem
15 ber 53 by the ?exible pipe 52 connected to 53
by the coupling 51.
Since the air used to inflate the bags I‘! is
preferably supplied under relatively high pres
sure it is important that the non-rotating valve
20 member 53 be held accurately seated in the ro
tating valve member 31, and to this end in the
construction shown, the valve member 53 is ac
curately ground to fit the member 31 and is yield
ingly held seated therein by a coiled spring 58
25 one end of which rests against an antifriction
ball 59 which ball rests in a pocket 69 formed
in a spider 6| that is seated in the outer end of
the valve member 53 and is secured to this mem
ber by screws 62. The valve members 31 and 53
30 are enclosed in a cover 63 that is secured to the
outer end of the member 37 by bolts 64 and the
cover 63 has the valve covering skirt 65 extend
ing towards the wheel. The central portion of
the cover plate 63 has a threaded opening adapt
CG Ll ed to receive the bolt 66 against which the outer
end of the spring 58 is seated and this bolt may
be adjusted to vary the pressure of the spring
upon the valve member 53.
The jack supporting wheel is retained upon its
40 supporting axle 29 by a nut 67 that is provided
upon the threaded end 23 of the axle, and the
nut bears against a washer 68. The inner valve
member 53 is ?oatingly connected to the axle 2|]
so that it is held from rotating by the axle, but is
~15 relieved from the weight of the wheel and is free
to seat accurately in the valve member 3'! under
the action of the spring 58. This result is secured
by providing on the axle 29 the washer 69 which
is keyed to the axle so that it can not turn and is
50 clamped between the nuts 61 and 19. The wash
er 69 has the slots 1| formed in its outer edge
(see Fig. 10) to receive the inwardly projecting
?ngers 12 upon the valve member 53 so as to
hold this member from rotating.
The mechanism so far described serves to sup
ply compressed air from the supply pipe 49 to
each jack as the port 4| or 42 controlling a jack
is brought into alignment by the rotation of the
wheel with a port 54 or 55, and the compressed
6O
air supplied to a jack through these aligned
ports is prevented from being exhausted from
the jack until the wheel has been turned through
nearly a complete revolution. The air is ex
hausted from a jack when the wheel is rotated
to align the port 4| or 42 with the exhaust groove
13 formed in the face of the valve member 53 a
short distance from the ports 54 and 55. The
groove '13 is preferably enlarged at 74 and T5 to
allow a longer period of time in which the air
might exhaust from the bags I? as the wheel
rotates.
It is important to thoroughly lubricate the co—
operating surfaces of the valve members 37 and
53 and this is accomplished in accordance with
the present invention by providing in the face of
3
7
the valve member 53 the grease receiving groove
16 to which grease is supplied through the con
duits 11 from a grease cup 78 mounted on the
spider 6|. The cover of the grease cup may be
tightened from time to time to feed grease to
the bearing groove 16 by inserting a screw driver
through any one of the openings 19 formed in
the cover plate 63. It is desirable to feed grease.
to this bearing when the wheel and its cover plate
63 are turned to di?erent positions relative to 10
the non-rotating valve member 53. The cover
plate 63 is therefore shown in Fig. 5 as provided
with thirty holes 19 numbered in irregular order
from I to 30 inclusive so that the screw driver
used in tightening the cover of the grease cup
may be inserted in a different hole 19 upon each
day of the month in the order shown by the nu
merals | to 30 opposite these holes.
When the jack supporting wheel is rotated
continuously at a uniform speed as contem 20
plated in the present case as the operator changes
the shoes in the successive jacks, it is important
that means be provided whereby he may quickly
‘in?ate a jack bag I‘! as soon as a shoe is properly
placed in the jack, and prevent the bag from
being in?ated before the shoe is properly placed
in the jack. This is accomplished in accordance
with the present invention by providing near
the base of the machine the pedal control device
89 having the foot operable plunger 8| for sup- f
plying compressed air through the pipe 49 and
aligned ports 4| and 54 or 42 and 55 to a par
ticular bag I1, and also having the foot oper
able plunger 82 for exhausting air through these
connections from the bag IT.
The construction of the device 89 is best shown
in Fig. 13 in which air under pressure is sup
plied to the chamber 83 through the inlet port 84
from any suitable source of compressed air not
shown. When the plunger 8| is depressed
against the upward pressure of the spring 85 it
will open the valve 86 and permit the com
pressed air to enter the upper chamber 81 and
conduit 66. Communicating with an intermedi
ate portion of the conduit 88 is the port 89 to 45
which is connected the pipe 49 leading to the
wheel axle. When it is desired to exhaust air
from a bag I'E while the controlling ports 4| and
54 or 42 and 55 are aligned the plunger 82 is de
pressed against the pressure of the spring 99 to
open the valve 9| so that the air from the bag ‘
I‘! may enter the chamber 92 and exhaust into
the atmosphere through the port 93. The pipe
49 and conduit 88 serve to in?ate and de?ate
the bag I‘! depending upon whether the plunger
8| or 82 is depressed, and the valves 89 and 9|
are so arranged that the pressure of the com
pressed air against them tends to hold them
seated.
It will be seen from the foregoing that the set GO
of thirty jacks are supported by a comparatively
small wheel and that these jacks are so supported
from the wheel that the machine operator may
quickly and accurately place the shoes in the
jacks as the wheel is continuously rotating, and
if a shoe is not properly positioned as a jack is‘
in?ated by stepping on the plunger 8|, it may be
immediately de?ated by stepping on the plunger
82 to exhaust the air from the jack so that the
sole may be properly positioned on the shoeand
the jack in?ated again. A particular jack is
under the control of the foot plungers 8| and 82
only while it is moving through a small are. below
the wheel axle and if it should be desired to
exhaust the air from a jack before it is carried by
4
‘2,076,697
vthe wheel around to the position of the exhaust
groove 13, the jack maybe de?ated by opening a
hand valve 94 with which each jack is provided.
. While in the construction shown the jack sup
porting wheel rotates in a vertical plane, this
wheel may be supported, if desired, to rotate in
a horizontal plane; and while the jacks shown are
designed more particularly for use in permanently
cementing soles in place, they may be employed
simply to shape the soles to the bottom of the
shoes, or to cement soles to the shoes when the
cement is relied upon to hold a sole in place and
keep it from creeping while the sole is being
stitched to the shoe.

front plate secured to said wheel over said non
rotating part, spring means con?ned between the
front plate and said part for holding the latter
seated, and an antifriction bearing at one end of 1O
said spring means.
15. In a machine of the class described in com
bination, a wheel provided with a series of air
con?ning means, pipes leading from the hub
portion of the wheel to said means, a shaft for 15
rotatably supporting the Wheel, valve mechanism
for controlling compressed air supplied to said
means through said pipes, including a valve casing
upon the wheel to rotate therewith and provided
ith a conical central bore that flares outwardly
away from the plane of the wheel, a tapered valve
part non-rotatably but movably secured to said
shaft and adapted to ?t said conical bore to form
an air-tight joint therebetween, and spring means
25

16. A machine for cementing soles to shoes com
prising in combination, a jack-supporting wheel
rotatably mounted and provided with an outer
rim, a series of jacks each having an in?atable bag
for pressing a sole against a shoe, each jack in
cluding a base plate adapted to support an inflat
able bag and an integral overhanging cantilever
arm for holding a shoe against the upward pres
sure exerted upon it when the bag is in?ated, each
jack being provided with a supporting bracket 35
upon its cantilever arm that extends laterally out
wardly from said arm, and means for securing
the brackets to said rim so that the brackets sup
port the jacks to project radially outwardly a sub
stantial distance from the rim and frontwardly in 40
a plane at right angles to the plane of the wheel
so that the jacks travel in a much greater circle
than that de?ned by said rim.
