between the hand wheel 30 and the arm 26. When
use of the machine is interrupted, the hand wheel
36 is loosened and the receptaclev 2| is lowered
into a position below the level of the bottom of
2,114,453
the trough I0 in order that the coating material
therein may drain back into the receptacle.
As will be seen in Figs. 4 and 6, the lower end
of the rib 23 is pivotally connected to one end
of a link 32 the other end oi’ which (Fig. 6) is
pivoted from the side wall I3 oi’ the frame. This
construction, together with the arm 24, rock
shai't 25, arm 28, and pivot points, provides a
four-bar linkage lever which insures that the re
10 ceptacle 2| will always be level whether in lowered
or raised position. To facilitate draining- both
the trough I 0 and the receptacle 2|, the T I8 is
connected to a conduit 33 (Figs. 4 and 6) provided
with an elbow 34 to which one end of a short
15 piece of pipe 35 is secured. The other end of the
pipe 35 is provided with a cap 36. Upon remov
ing the cap 36 the pipe 35 is swung downwardly,
the elbow 34 turning on the conduit 33, in order
to drain' the trough I 8 and the receptacle 2I.
20
Mounted to dip into the: trough I8 are two
non-contacting, longitudinally fiuted, cylindrical
work supporting and coating rolls 31 and 38
(Figs. 2, 6 and 9) arranged to project through
the _open top of. the -trough I8. The roll 31,
which is the first of these two rolls to engage
the leading edge of the sole'as it passes through
the machine, is a solid metal roll. As shown in
Fig. 2 the roll 31 is provided on its opposite ends
with cylindrical portions 39 and 40, respectively,
of reduced diameter. The end portion 39 is jour
naled in a slot 4I (Fig. 3) formed in the side
wall I3, and a gear 42 (Figs. 2 and '7) is secured
to the free end of the portion 39. In this free
end the portion 39 is provided with a conical
'35 center which engages and rotates on a conical
point 43 (Figs. 1, 2 and 3) projecting laterally
from the inside face of a bracket 44 supported
from the side wall I3. The end portion 40 of
the roll 31 is also provided with a conical center
40 45 (Fig. 8) which engages and rotates on a coni
.cal point 46 formed on one end of a rod 41. The
rod 41 is longitudinally movable in a split sleeve
48 secured to the side wall i4, and the sleeve 48
is provided with external threads which are en
45 gaged by internal threads on a hand-wheel 49.
With this construction the hand-Wheel 49 may
be loosened to allow the split sleeve 48 'to expand
and thus release the rod 41 which may be then
moved longitudinally in the sleeve 48 to with
50 draw the point 46 from the center 45. The roll
31 and its associated gear may then be removed
bodily from the trough I0.
The gear 42 meshes with a gear 50 (Figs. 2, 3
and 7) formed on a sleeve 5I which is rotatably
55 mounted on the cylindrical end portion, project
ing through and beyond the side wall I3 (Fig. 3),
of a bar 52 extending between the side walls I3
and I4 centrally of the trough I8. 'I'he opposite
end of the bar 52 is also cylindrical and is
mounted in the side wall I4. The structure of
that portion of the bar 52 lying within the
trough will be described'hereinafter. The sleeve
5I is secured to a double grooved pulley 53 rotat
ably mounted on the projecting end of the bar
52, and for driving the pulley 53, the frame I2 is
provided with an electric motor 54 on the arma
ture shaft 55 of which a double grooved pulley 56
is secured. The pulleys 53 and 56 may be pro
in the same manner as described previously in
connection with the roll 31. Intermediate its
ends the spindle 58 is provided with an hexagonal
portion 6I which forms a core for a sponge-rubber
body portion 62. The body portion 62 is inter
posedvbetween two washers 63 and 64 mounted
on a cylindrical portion of the spindle 58, and
the washers are held in place b_y collars 65 and 66,
respectively, secured to the spindle 58. The body
portion 62 isfcovered by a synthetic rubber cover 10
61 provided on its coating applying surface with
longitudinal flutes. The principal characteristic
of the synthetic rubber is that it is compounded
to resist any tendency of the latex to stick .
thereto.
15
The spindle 58 is provided with a gear 68 (Figs.
2, 5 and '1) which meshes- withthe gear 50.
With this construction the two work supporting
and coating rolls 31 and 38 are driven in the
same counter-clockwise direction (viewing Fig. 6) 20
and at the same speed.
.
.
Cooperating with the lower work supporting
and coating rolls 31 and 38 is a smooth-faced
cylindrical upper roll 69 (Fig. 6) provided on its
opposite ends, as shown in Fig. 3, with cylin 25
drical portions 10 and 1I, respectively, of reduced
diameter. Thesereduced ends 10 and 1I engage
and freely rotate on conical points 12 and 13,
respectively, supported from an arm 14. The
point 13 is formed on one end of a rod con
30
structed and mounted as shown in Fig. 3 in the
same manner as the rod 41 (Fig. 8), so that the
roll 69 may be mounted or removed in the manner
of the rolls 31 and 38.
'
,
The arm 14 is provided with a rear yoked end
15 (Fig. 1), a front yoked end 16, and a central
curved bridge 11 (Figs. l and 6) overlying the
upper roll 69 and forming a guard therefor. The
rear yoked end 15 is provided with a pair of
conical points 18 (Figs. 2, 3, 4, and 6) which en 40
gage, respectively, centers formed in the oppo
site sides of a yoked arm 19 (Figs. 1, 2, 3, 4,
and 6) which is pivotally mounted on the rock
shaft 25 (Figs. 4 and 6). As indicated in Fig. 4,
the arm 14 is adapted to be ~tipped upright,
swinging into this position on the conical points 45,
18 engaged with the centers on the arm 19. But
since the arm 19 is itself pivotally mounted on
the rock-shaft 25, it is clear that the pivotal axis
of. the arm 14 on the arm 19 may be shifted. 50
Stated in another way, any movement of the
arm 19 about its lpivotal axis,_ formed by the
rock-shaft 25, necessarily causes the centers on
the arm 19, and therefore the conical points 18 '
and the arm 14, to move also. The purpose of 55
this construction will be described hereinafter,I
but it may be said that thepivotal axis of the
arm-14 on the arm 19 may be maintained in a
fixed position of adjustment during the operation
of the machine by meansof a thumb nut 80
(Figs. 4, 6 and '1) and an adjustable stop-screw
8I (Fig. 6). As best shown in Fig. 6 the thumb
nut 80 is threaded on the end of a rod 82 pro
jecting rearwardly from the trough I I) through a
lug depending from the arm 19. 'I'he thumb nut 65
88 holds a washer in engagement with the lug
on the arm 19 so that the swinging of. the arm
are crossed as indicated in Figs. 1, 2 and 3.
The roll 38 is built up on a spindle 58 (Fig. 5)
the opposite ends of which are provided, respec
19 to the left on the rock-shaft 25, viewing Fig. 6,
may be limited as desired. The swinging of the
arm 19 to the right from the position determined 70
by the thumb nut 80 is prevented by the stop
screw 8I which, as shown in Fig. 6, is carried by
the arm 19 and is adapted to abut the rear

its width, thus insuring the simultaneous appli
movement of the roll 88 is limited definitely by
the bottom ends of screws 83 and 84,. (Figs. l
and 2), which engage, respectively, the tops of
the side walls I3 and I4. The screws 8_3 and 84
are threaded through the front yoked end 18
and are locked thereon in the desired position of
adjustment ‘by lock-nuts 88 (Fig. '1) and 88 (Fig.
10 4) , respectively.= During any shift of the pivotal

planiform surfaces of a shanked-out sole.
In order to increase the tendency of the bent
sole to press itself iirmly into engagement with
'the coating rolls`31 and 38, the arm 14 is pro
vided with two small rotatably mounted cylin
drical rolls 88 and 81 (Fig. 6), one of which, the
roll 88, engages the leading edge of the sole first, 10
and the other one of which, the roll 81, engages
the trailing edge of the sole last during the pas
sage of the sole through the machine.

such as shoe soles. In this class of work only on a double-yoked arm 88 pivotally mounted on
one face is coated, and therefore it is essential conical points |00 and |0| carried by the front
20 that the upper roll 88 be kept free of coating in Ayolxed end 18 of the arm 14. The roll 88 is 20
order to prevent soiling the uncoated face of the
work. This desideratum is4 obtained, whether
work is in the machine or not, by maintaining,`
through the adjustment of the screws 83 and 84,
25 the periphery of the roll 88> spaced from the
peripheries of the rolls 31 and 38 a distance at
least greate'r than the thickness of the work.

the arm 88 is provided with a pair of ears |02

and I4 are provided, respectively, with rotatable
blocks 81 (Fig. 7) and 88 (Fig. 4)'each provided
with an opening which loosely receives a rod 88
threaded at its lower end upon a nut 80. Coiled

the work. With the roll 69 equally spaced in this
manner from the rolls 31. and 38, the amount of
sole flexion at the contact points of. the sole with
the rolls 31 and 38 will be equal. Stated in an
other way, the sole will press itself equally hard
upon each of the rolls 31 and 38 because the
amounts of flexion at those points are equal. If,
however, the roll 69 is nearer to one of the lower
rolls than it is to the other, the nearer together
10 will be the contact point of the roll 69 with the
grain face of the sole and the contact point of
the lower roll in question with the flesh face of
the sole, and the greater will be the flexion of
the sole in the vicinity of the two rolls. The
15 greater the flexion. the greater will be the pres
sure of the sole upon the lower roll. This'is of
practical importance in coating the skived por
tions of thick soles. The roll 38, being made of
yielding material, is adapted to conform to the
20 flesh face of the sole across its width, thereby
coating the skived as well as the unskived por
tions thereof; but the thicker the sole, the harder
must it press itself into the roll 38 to effect this
coating and the greater will be the resistance both
25 to ñexion of the sole because of its thickness and
to a depression of the material of the roll 38.
The pressure of a sole of a given thickness on the
roll 38 when the roll 69 is equally spaced from the
rolls 31 and 38 may be just sufficient to cause a
30 coating of the skived portions of the solel but
insumcient to cause a coating of the skived por
tions of a thicker sole. _As a consequence, by
adjusting the thumb nut 80 and the stop-screw
8|, the arm 14 may be moved to the left, viewing
35 Fig. 6, to cause the upper roll 69 to be located
' nearer to the roll 38 than to the roll 31, thereby
insuring a proper coating of the skived portions
of thick soles.
Viewing Fig. 6, it will be seen that in any swing
40 ing of the arm 14 upon the pivotal axis compris
ing the conical points 18, the roll 96 has a greater
arcuate movement than do the rolls 69 and 91
and the roll 69 has a greater arcuate movement
than does the roll 91. More particularly, the pe
45 ripheral portions of the roll 69 which are adjacent
the roll 31 have a greater arcuate movement than
do -the peripheral portions of the roll 69 which are
adjacent the roll 38. It has been Vpointed out
- labove that the downward swinging of the arm 14
50 is limited by the adjustable screws `83'and 84.
With this construction and operation, it is ap
parent that with the thumb nut 88 and the stop
screw 8| so adjusted as to cause the roll 69 to
be located centrally over the rolls 31 and 38, the
55 screws 83 and 84 may be adjusted to cause a
downward swinging of the arm 14 on its pivotal
axis under the inñuence of gravity. This down
ward swinging, because of the above stated posi
tion of the roll 69, causes the peripheral portions
60 of the rolli 69 which> are adjacent the roll 31 to
approach closer to the roll 31 than the peripheral
portions of the roll 69 which are adjacent the
this construction and mode of operation the ma
chine is adapted to operate upon work differing '
widely in thicknesses.
,
.
The soles are fed into the machine from a table
iI3 supported partially by extensions (Figs. 2
and 6) of the side walls I3 and I4 and partially
by a post II4 (Fig. 4) secured to and projecting
'upwardly from the base I2.
»
In order that the soles may be coated properly,
doctors for controlling the amount of coating ma
terial delivered to the work are associated with
the up-going sides of the rolls 31 and 38, respec
tively. The up-going side of the roll 31 is as
sociated with a doctor II6 (Fig. 6) comprising
a plate (Fig. 3) secured to the front wall I6 and
provided with a rear straight edge spaced from
the peripheral surface of the roll 31 about .0015
of an inch throughout its extent. In order to
break up bubbles and to prevent strings of latex
from being flicked upwardly into engagement 20
with the'upper roll 69,-the extensions of the side
walls I3 and I4 support pivotally a plate III
the rear edge of which is beveled to overlie close
ly the roll 31. The front edge of the plate II6 is
provided with a tail II1 which carries an adjust
able stop screw II8 (Fig. 6) arranged to engage
the under surface of the table II3 and hold the
beveled edge of the plate II6 in its desired posi
tion of adjustment. As shown in Fig. 6, the top
surface of the plate II6 lies in a plane above the 30
uppermost element of the surface of the roll 31.
The up-going side of the roll 38 is associated
with a doctor II9 (Figs. 6 and 9) comprising a
ñat plate having a straight edge |28 spaced close
ly from the peripheral surface of the roll 38 35
throughout its extent. The doctor |I9 is adapt
ed to be adjustably secured to the bar 62, and to
this end the upper portion of the bar 52 is cut

is slightly longer than the doctor I I9, as indicated 40
in Fig. 3. The doctor II9 is provided near its
ends with a pair of slots I 22 which embrace, re
spectively, the shanks of screws |23 for securing
the doctor I I9 to the surface I2| with the straight
edge |02 in a desired position of nearness to the 45
roll 38. The doctor II9 is also provided near its
ends with a second pair of slots |24 which em
brace, respectively, posts I25 (Fig. 9) threaded
into the bar 52 and rising vertically from the flat
surface I2I.
Mounted on the posts I 25 is a 50
straight edge |26 which serves to break up bub
bles of latex and to prevent strings thereof -from
being flicked upwardly from the doctor II9 into
engagement with the roll 69 in the same manner
that the beveled edge of the plate II6 performs 55
these functions in connection with 'the roll 31
and its doctor II5.
In operating the machine to coat the flesh
faces of soles. the operative with her right hand
places a sole flesh face down upon the table II3 60
and pushes it through the space between the
plate H6 and the roll 96 so that the leading edge
roll 38 approach the roll 38. IStated in anotherl of the sole passes across and over the roll 31 into
engagement with the roll 69. The sole is pushed
way, by reason of the adjustable screws 83 and
65 84 and the pivoting o`f the arm 14, the roll 69 may
be moved to a position in which it is closer to the
~ roll 31 than to the roll 38. It may be in this swing
ing of the arm 14 to position the roll 69 as just
hard enough so that it commences to bend down 65
wardly in engagement with the roll 69, and since
`the roll 31 is driven, as soon as the leading edge
`of the sole begins its downward bending, traction

Moreover, by manipulating the thumb nut 88

75 it is closer to the roll 31 than to the roll 38. With

the roll 69, the leading edge of the sole traverses
the space between the rolls 31 and 38 until the
leading edge strikes the upgoing side of the roll

ing edge of the sole, thereby in turn causing the
grain face o'f the sole -to be wrapped around a
portion of the periphery of the roll 88 and caus
ing the ñesh face of the sole to press against the
rolls 31 and 38 at points spaced from the wrapped
portion. In this position the flesh face of the
sole is bent convexly about an axis extending at
right angles to the length of the sole. ' As the
leading edge of the sole continuas in its passage
through the machine it next tends to pass up
ward into the space between the rolls 88 and 81.
In order to prevent the turned-up’ leading edge
of the sole from passing upward into the space
between the rolls 88 and 81, the bridge 11 sup

rolls 31, 68, 38 and 81 cooperate, and then finally
the rolls 88, 38 and 81 cooperate.
Nothing herein explained is to be interpreted as
limiting the various features of the present in

connection with the particular machine or the
particular mode .of operation 'or any combination
thereof selected for purposes of illustration and
explanation. While the particulars of construc

artisan without departing from the true scope of
the actual invention, characterizing features of

When the leading edge of the sole is bent
downwardly under the roll 81, the ñesh face of
30 the sole is wrapped around a portion of the pe
riphery of the roll 38. The feed of the sole con
tinues, the- trailing edge of the flesh face of the
sole successively passing over the table ||3, the
plate ||6, the roll 31 and the roll 38. As soon as
35 the trailing edge clears the space between the
rolls 31 and 38, the leading edge of the sole has
been projected out of the space between the pe
ripheries of the rolls 38 and 81 far enough for the
operative to grasp with her hand the leading edge
40 of the sole, which extends conveniently down
wardly because of the bending imparted by the
roll 81, after which the sole passes out of the
machine.

l
From the foregoing it .will be seen that in spite
of the fact that the upper roll 88 is spaced from
the'peripheries of the lower rolls 31 and 38 a
distance at least greater than the thickness of
the work, there is suflicient traction to feed the
sole through the machine so long as thesole is
bent in engagement with» the rolls 31 and 68, or
31, 88, and 38, or 31,*88, 38 and 81, and also, dur
