Improvements in Sole Laying Machines, in part also applicable to
Sole Levelling Machines.
A communication from abroad by THE GOODYEAR SHOE MACHINERY COMPANY,
of Boston, Massachusetts, United States of America.
1, JAMES GRIEVE LORRAIN, M.I.E.E., M.I. Mech. E., of Norfolk House,
Victoria Embankment, London, W.C., in the County of Middlesex, Chartered
Patent Agent, do hereby declare the nature of this invention (as communicated
to me from abroad) to be as follows:-
The present invention relates to improvements in machines of the above class and
consists of certain improved mechanisms for relatively actuating the jacks and
forms, operating automatically and successively to seat the forms, and bring the
jacks and forms into a position of pressure, of connections between said mechanisms,
whereby the operation of the jack seating mechanism, automatically adjusts the
pressure mechanism to the height of the shoe upon the sole of which the form is
seated; of improvements in the construction and arrangement of the jacks and
forms; and of improved devices and combination of devices as hereinafter more
specifically set forth.
The object of the present invention is to increase the capacity and accuracy of
operation of machines of the above designated class, and to eliminate as far as
practical therein the liability of injury to the shoe or its last.
The present invention is illustrated in the accompanying drawings in which
Figure 1 is a front elevation of a machine embodying the same, with portion of
one of the cams removed to show underlying parts.

carrier.
Figure 9 is a partial rear view illustrating the stopping and starting mechanism.
Figures 10, 11 and 12 are detail views of one of the pressing forms.
Similar letters and figures of reference refer to similar parts throughout the
Beveral views.
In the drawings A represents a frame suitable to support the working parts of
the machine.
In practice I construct the frame A, with a suitable base a, to which are
secured the standards a' and a', the frame A may be however of any other suitable-
form.

page_text: In the frame A is mounted a suitable rotary carrier, conveniently in the form of
a spider frame B, which is arranged to receive a series of partial rotations, for the
purposes hereinafter described, stopping automatically, and being started at the
will of the operator.
A preferred, though by no means essential, form of mechanism for securing the
above result is shown in the drawing and described as follows:-
The spider frame B is rigidly secured to and rotates with a shaft b, which is
mounted and free to turn in suitable bearings in the standards at and al of the
frame A.
The shaft bis projected through its bearing in the standard a³, and back of the
standard a, carries a worm gear 6', which is engaged by a worm 6, on the shaft 6.
The shaft is mounted in suitable bearings in the frame A, in which it is free to
rotate, and is conveniently driven by means of the usual pulley 6. The pulley b
turns loosely about the shaft b³, and is connected therewith by a suitable clutch,
mechanism being provided at the control of the operator for engaging the members
of the clutch to cause the shaft 6 and pulley b to rotate together, and automatically
operating mechanisms being provided, whereby the members of the clutch are
disengaged to stop the rotation of the shaft 63, and allow the pulley to turn
loosely thereon.
While the form of the clutch, above referred to, or of its actuating mechanism
in itself forins no part of the present invention, it may be desirable in this connection
to briefly describe the specific form.shown and its connection with other features
of the machine.
The pulley b, being as before stated free to rotate independently of the shaft b³,
is also arranged to slide along said shaft and the inner face of its hub is provided
with a segmental slot (not shown), which is engaged by a pin 2, upon a disk 3
which rotates with and is held from motion along the shaft 63 (see Fig. 9).
Adjacent to the shaft 3 is a substantially parallel shaft 6, mounted in suitable
bearings in the frame A, or the brackets 4, 4 thereon, in which it is free to rotate
and slide longitudinally being guided and held in position thereby. On the
shaft is a sleeve 5, free to turn thereon, but held from movement along the same
by suitable collars. To the sleeve 5 is secured a fork or collar 6, which engages a
groove on the hub of the pulley . The shaft & also carries a bent lever 7, which
turns therewith, and is held from motion along the same. The lever 7, by means
of a spring 8, secured to an arm 9, on the shaft b, and to a fixed part of the
machine, or by some other suitable device, is normally held in such position that
the upper end thereof projects in the path of a series of stops or dogs 10, 10 etc. on
the gear , the above described arrangement being such that as the gear
rotated, one of the stops 10, coming in contact with the lever 7, moves it and the
shaft outward, and, by means of the collar 6, moves the pulley outward,
causing the pin 2 to be withdrawn from the segmental slot in the hub of pulley b*,
and allowing the pulley to rotate independently of the shaft b³.
is
At or near the lower end of the lever 7 is formed a socket 12, which receives
the upper end of a rod 14, the lower end of which rests in a socket 15, formed
upon the treadle &, fulcrummed at 16 on the frame A, or the lever 7 may be
otherwise suitably connected with the treadle 6, so that a depression of the
treadle causes the lever 7 to tip backward out of the path of the dog 10. When
the lever 7 has cleared the dog 10, a suitably placed spring 17, closes the clutch,
causing the shaft to rotate with the pulley +, and the spring 8 again advances
the lever 7, bringing its front end again into the path of the dogs 10.
The number and position of the dogs 10 will depend upon the number and
position of the jacks on the spider frame. In the form of my invention shown in
the drawings in which the spider frame is provided with four jacks at substantially
ninety degrees apart, I have used four dogs 10 (only two shown) at substantially
ninety degrees apart from the gear b¹.
Upon the carrier B are mounted a series of pressing forms D, D etc., and a series
of shoe supporting jacks E, E etc.

page_text: While any suitable pressing form can be used in combination with the mechanisms
berein described without any departure from the present invention, I have in
practice adopted a pressing form which in order that one skilled in the art may
readily construct a machine embodying my invention in the best form known to
me, I will now describe in detail.
The form D as shown in the drawings comprises a rigid bed d (Figures 10, 11
and 12) having the general longitudinal contour of the bottom of a last, and to
which is suitably secured a flexible pressing pad d.
The pressing pad d is formed of a continuous block of rubber or other suitable
elastic material, and provided with a projected shank portion d, and a reinforcing
strip d³, covering substantially the edge pressing portions of the pad, substantially
as shown in my said Letters Patent.
Between the shank portion d' of the pad d and the bed d is locate the shank
block d, which bears upon the pad d' at the points d and d, upon opposite sides
of the shank, and adjacent to the base of the reinforcing strip .
Upon the bed d is formed a hoss d, in which is formed a chamber d', which
extends through the bed d. To the block is secured a stem which is fitted to
the bore of a tubular threaded bolt d, which engages correspondingly threaded
bearings in the top of the boss d. Upon the stem do is a collar d, free to slide
thereon, and between which and the block is placed a coiled spring d". The
inner end of the bolt a bears upon the ellar d", the above described arrangement
being such that the block dis held in contact with the pad d' at the points and d
by the action of the spring d", which may be regulated by moving the collar d'
along the stem d, by turning the bolt d10 in its threaded bearing. When pressure
is applied the stem moves along the bore of the bolt do to allow the block d' to
be forced toward the bed d, the stem d acting to guide the block and keep it
in its proper position. The chamber d' is preferably enlarged at its base to form a
recess d" which receives the upper portion of the block d', so that the same will
not when forced against the bed d, form a ridge across the form which would be
apt to mark the sole.
The advantages which I claim for a forin constructed as above described are its
increased accuracy of operation particularly at the edge portions of the shank, thus
ensuring an evenly laid sole, and the absence of any ridge or projection in the rigid
parts thereof which would tend to mark or otherwise injure the sole.
The jacks E may also be of any suitable construction. I find however, in
practice, that a form of jack substantially similar to that shown in the drawings
secures the best results, partly on account of the ease and rapidity with which it
can be adjusted but principally because it makes a point upon the shank portion of
the shoe a positive point for all sizes of shoes, thereby always bringing the shank
portion of the shoe under the same part of the form, a result of great importance in
connection with a form having a projected shank portion, as shown in the
drawings.
As shown in the drawings each of the jacks E comprises a toe reste and a heel
support el, the bases of which are fitted to a dove tailed groove e in the base
plate e, both the toe rest e and heel support el being movable along the plate e,
toward and away from each other. On the plate e is eccentrically pivotted a
lever e, in the longer arm of which is formed a slot e (see Figure 7) which
is engaged by a pine, upon the toe rest e, or a suitable projection e' thereon.
In the shorter arm of the lever e is formed a slot es, which is engaged by a pine,
secured to a projection , upon the heel support e. The above described
arrangement is such that a movement of the toe rest e along the plate e causes a
movement of the heel support e' in an opposite direction and to a less extent, and
vice versa.
The relative length of the arms of the lever et, determines the relative movement
of the toe rest and heel support, and since there is a proportional variation in the
lengths of the several parts of a sole in the different sizes of shoes it is evident that
the lever e can readily be arranged so that the shank of a large shoe will ba

page_text: brought to substantially the same position under the form as the shank of a
small shoc.
I am aware that in certain forms of sole machines it has heretofore been proposed
to so arrange the jack that the toe of the last is made a positive point for all sizes,
while in others the positive point is at the heel, or at the centre, but so far as I
am aware of the art no jack has been heretofore provided in which a point on the
shank is made the positive point for all adjustments for length.
The toe reste and heel support e' as above arranged may be conveniently locked
in any desired position by means of a spring pressed pawl e, mounted upon
the toe rest e, and arranged to engage a series of notches e¹ upon the
plate.
In all machines einbodying a rotary carrier and series of jacks and forms thereon,
there are three essential movements, first; a rotation of the carrier second; a
relative movement of the jacks and forms from a position of clearance to a position
of pressure, and third; a movement of the jacks, out of operative relation to the
forins, whereby they are presented to the operator in convenient position for the
removal or adjustment of work. I may say in this connection that the jacks and
forms are said to be.in a position of pressure when their relative position is such
that the sole of a shoe upon a last, placed upon the jack, would be sufficiently
compressed against the form to properly perform the sole laying operation, and that
the jack and forms are said to be in a position of clearance when their relative
position is such that the jack can be moved, with a shoe thereon, away from the form
into a convenient position for the removal of a shoe therefrom.
Having hereinbefore described a preferred form of mechanism for rotating the
carrier, will now describe a preferred form of mechanism whereby the jacks
and forms are moved relatively to each other to produce compression and
clearance.
In accordance with the present invention the relative movement of the jacks and
forms, from a position of clearance to a position of pressure, occurs in two steps,
the first step seating the form firmly on the sole of the shoe upon the jack, and the
second step bringing the form and jack into a position of pressure, that is, forcing
them together with sufficient pressure to successfully perform the sole laying
operation.
The advantage which I gain by dividing the relative movement of jacks and
forms as above explained is that I am thereby enabled to use a powerful positively
actuated mechanism for producing pressure which is automatically adjusted by the
senting of the form to the height of the last, and thus while securing great pressure,
to avoid any danger of injury to the last or shoe.
As shown in the drawing each of the forms D is supported by a swinging lever F,
which I have hereinafter called the form lever and which is fulerumed at f on one
of the arms of the spider frame B.
The lever Fin practice consists of the substantially parallel arms f', f' (see
Fig. 8) united at one end, and at the opposite end embracing a sleeve, upou the
spider arm b. A trunnion extending through both of the arms f, and the
sleeve secures the lever F to the spider arm and leaves it free to operate as
hereinafter described. The form D'is preferably secured to the lever F by a
trunniony, which is mounted in the arms f', f', and extends through a bearing dis
in the boss d (see Fig. 10), leaving the form D free to tip longitudinally,
In practice the bearing d is located substantially over the centre of the bed d,
and I have provided near each end of the bed d, a coiled spring (see Fig. 10)
which bears against the bed d and a movable plate. In the lever Fare provided
threaded bearings, which receive the bolts, the lower euds of which are fitted
to suckets in the plates. Each of the plates has upon its under sido a
circular boss 20 which engages one or more coils of the spring, and prevents the
same from slipping from the plate. A. similar boss, and for a similar purpose, is
formed upon the bed d.
The above described arrangement is such that by turning the bolts f, f, the

page_text: action of the springs, may be regulated as required, so that the longitudinal
tipping movement of form D is controlled by elastic adjustable stops, which is a
feature of considerable advantage in this class of machines.
As shown in the drawings the seating of each of the forms D is accomplished by
means of a spring H, which is secured to the lever F, and to the spider frame B,
conveniently at the points and h¹.
To the standard a² of the frame A, is bolted or otherwise suitably secured a
cam C the form of which will be hereinafter more fully described, anl upon the
lever is secured a cam roll e, or other suitable projection, which as the spider
frame B rotates engages the eam C, and raises the form D into a position of
clearance.
As the spider frame B is further rotated, the cam roll c leaving the cam C, the
spring Hacting upon the lever F, brings the form D down upon the sole of a shoe
upon the jack E.
While it is preferable that the form should be firmly seated upon the sole by
the spring H, as above explained, it is not intended thereby to secure sufficient
pressure to perform the sole laying operation, although by increasing the strength
of the spring H, or by substituting therefor a series of springs, such operation can
be successfully accomplished upon many grades of work, and further mechanism for
securing pressure dispensed with.
1 will now describe in detail the form of mechanism shown in the drawing by
which after the form is seated I secure the necessary amount of pressure to properly
lay the sole.
Reference being had more particularly to Figures 3, 4, 5 and 6 of the drawing,
R represents a link pivotally connected with the lever F, preferably adjacent to
its free end, and also pivotally connected with a reciprocating rod r, or a suitable
offset fixedly secured thereon.
In practice I have provided a casing 2 which is bolted or otherwise fixedly
secured to the spider frame B, and in which are provided bearings 3 and 4 (see
Figure 5) in which the rod r is free to reciprocate longitudinally being guided and
held in position thereby.
On the rod r is a collar, free to slide along the rod r, and from which is
projected an arm, which is acted upon by a lever, conveniently pivotted at
upon the spider frame B, and carrying a cam roll, which works upon a cam R',
bolted or otherwise suitably secured to the standard a² of the frame A. The
collar is supported by a suitably placed spring 10, which may conveniently
consist of a coiled spring surrounding the rod r, and bearing against the collar ³
and the offset, projecting from the spider frame B.
The rod extends through the offset and a bearing for the rod r is provided
therein.
The above described arrangement is such that the rod r is free to slide through
the collar, until the lever is depressed by the action of the cam R' upon the
cam roll, but when the lever is depressed as above stated, acting upon
the arm it cramps the collar on the rod r and forces down said rod for the
purposes hereinafter stated.
When the shape of the cam R¹ permits the cam roll to approach the centre
and thus relieve the pressure on lever ', the collar is no longer cramped,
but the rod r is again free to slide through the same and the collar is returned
to its original position by the action of the spring 10. Of course it is understood
that the collar has a comparatively short bearing on the rod r, and when power
is applied away from the rod toward the end of the arm r, the collar becomes
cramped or binds on the rod r, forming a positive and easily controlled clutch,
which is capable of sustaining great strain without danger of breaking or slipping.
To allow for the relative movement of the lever and the arm, I have in
practice made the following provision:-
On the arm is a collar l, free to turn thereon, but held from movement along
the same.
The collar is provided, upon opposite sides, with suitable sockets

page_text: which are engaged by the inner ends of the thread bolts 12, 13, having bearings in a
link, which surrounds the collars l.
From the link is projected a cylindrical stem 1, which is fitted to a sleeve 15, on
the lever. The stem 13 is free to rotate in the sleeve l, and is held in position
therein by a suitable collar 1. I would say that in practice, the motion of the
lever being on both sides of the centre, the above described arrangement with
the common machine fits will allow sufficient play of parts, and is simple and
-durable.
It is evident that when arranged as shown in the drawing if the jacks E are
empty, the rod r, before pressure is applied will be moved downward through the
collar, by the action of the spring H, acting through the lever F and link R,
until the lever F rests upon the casing, or some other fixed portion of the
machine, and it is further evident that if, when the parts are in the position above
stated, the cam R' is allowed to act upon the lever to further depress the rod,
some part of the machine will be broken or strained.
To avoid the above stated difficulty I have provided what I have called a safety
device, and which as shown in the drawing consists of a stop R2 dependent from the
rod », conveniently from the offset and which, before the lever F cones in
contact with any fixed portion of the machine, strikes the collar, and depresses
the same until the arm, acting upon the lever r, raises the cam roll away
from the cam R', so that it cannot be acted upon thereby. The above described
device will be again referred to, and its operation more clearly explained, in
connection with the description of the operation of the machine of the drawing
hereinafter given.
The mechanism herein before described as associated with one of the forms being
substantially similar to that associated with each of the other forms, no further
-description thereof is considered necessary herein.
I will now describe the mechanism shown in the drawings whereby the jacks are
moved out of operative relation to the forms.
From the bed plate es of each of the jacks E, are projected the lugs n, n, in which
is fixedly secured a shaft n', having bearings in the projections n², n2 on the spider
frame B. From the base plate ea of each jack E is projected a fixed arm n³, the
outer end of which (preferably provided with a cam roll) bears upon a cam N,
bolted or otherwise fixedly secured to the standard a' of the frame A. A suitably
placed spring preferably consisting of a coiled spring n', coiled about the shaft n',
and secured thereto and to the spider frame B, acts to throw the jacks outward,
and to keep the arm n³ in contact with the cam N.
In practice I make the cam N circular except at the top where a depression n is
formed. The above described arrangement is such that as the spider frame B
rotates the arm n³ of each jack E, bearing against the cam N holds the jack in a
substantially vertical position under its form D until the arm n falls into the
depression n of the cam N, when the spring n forces the jack out of operative
relation to its form, presenting it to the operator in convenient position for the
removal or adjustment of the work. A further rotation of the spider restores the
jack to its vertical position under the form.
In practice I have provided a shelf P, at the top of standard a² of frame A,
which projects over the spider frame B, and affords a convenient and easily
accessible place for the operator to keep his soles while using the machine.
While the specific form of the several cams hereinbefore referred to is by no
means an essential feature of the present invention, I will give a brief description
of the forms thereof as shown in the drawings, and which I have found in practice
to operate successfully.
The cam R' may conveniently be formed substantially as shown in Figure 6
with an outer circular portion 30, and an inner circular portion 31, connected by
the inclined portions 32 and 33. The cam, R' is in practice secured upon the
standard a with the inner circular portion at the top, and symmetrically arranged
with reference to the vertical diameter of the spider frame B.

page_text: The cam N may conveniently consist of a circular disk, with the depression n³;.
which, when the cam N is in place upon the standard a', is at the top of the cam..
and symmetrically disposed with reference to the vertical diameter of the spider
frame.
The cam C may conveniently be formed with a circular central portion 40, and
inclined end portions 41 and 42. When secured to the standard a the cam Cis
also symmetrically disposed with reference to the vertical diameter of the spider
frame.
The relative extent of the several portions of the cams above described will be
readily understood from the following description of the operation of the machine.
Assuming the parts of the machine of the drawings to be in the position shown.
in Figure 1, the upper form D being in a position of clearance, with its cam roll c
resting upon the circular portion 40 of cam C, and the jack E associated with said.
form being out of operative relation thereto, with its arm resting in the
depression n of the cam N, and the cam roll being upon the inner circular-
portion of the cam R', so that the rod r is free to slide through the collar, power
being applied to the pulley , the operator having removed the finished work and
jacked the shoe to be operated upon, places the cemented sole in position, and by
depressing the treadle sets the spider frame B in rotation.
As the spider frame B rotates the arm n³, being carried out of the depression n³
onto the circular portion of the cam N, raises,the jack E against the action of the
spring n', and brings it into operative relation to the form D. As soon as this is.
done the cam roll c being carried down the inclined portion 42 of the cam C, allows.
the spring H to depress the lever F until the form D is seated upon the sole un.ler
the pressure of spring H. While the spring H has been seating the forin D on the
sole it has also, by means of the link R, been depressing the rod r through.
its collar. When the form D has been seated as above stated the rotation of
the spider frame B brings the cam roll onto the inclined portion 33 of the
cam R, and the lever being depressed cramps the collar on the rod r, and
depresses said rod and the form D until the cam roll has reached the outer-
circular portion 30 of the cam R', when the form is in its position of maximum.
pressure.
It is to be noted in this connectiou that the mechanism for giving the final
motion of pressure to the form D is automatically adjusted for the height of each
Jast, and thickness of sole thereon, by the seating of the form, so that all lasts
whether bigh or low are subjected to an equal amount of pressure, a result of
greatest importance in machines of this class.
The form D continues in the position of maximum pressure until the rotation of
the spider frame B brings the cam roll around to the inclined portion 32 of the
cam R', when the lever is released, releasing the rod r, and the cam roll e-
engaging the inclined portion 41 of the cam C, passes up onto the circular
portion 40 of said cam, raising the lever F, and bringing the form D into a position
of clearance, when the arm n³ drops into the depression n in the cam N, allowing.
the spring n to throw the jack E out of operative relation to the form D, and the
rotation of the spider stops. When four jacks are used as in the machine of the
drawings the rotation of the spider frame B is stopped at every quarter turn
leaving one form in position of clearance and its jack out of operative relation
thereto, while all the other jacks are under pressure. When a different number of
jacks is used a stop is made for each jack as above explained.
As the operation of the mechanism associated with each forin and jack are.
substantially the same, the above description is regarded as sufficient.
It is of course understood that the operator removes the work from, and adjusts
new work upon, the jacks, successively, as they are thrown out of operative
relation to their forms.
Should any of the jacks be left empty, and the spider frame B set in rotation,
when the can roll c reaches the inclined portion 42 of the cam C, the spring H acts
to depress the lever F as before described, but before the lever F comes in contact.

page_text: with the casing, or any fixed portion of the machine, the stop R2, strikes against
the collar, and depresses the same until the cam roll clears the cam R', so that
while the spider B is making its rotation the cam R' does not act to further
depress the rod r.
To adjust any of the jacks E, for any length of last, the operator disengages the
pawle, and moves the toe reste, until the toe reste and heel support are in
position to properly support the toe and beel of the last, which, without further
interference on the operators part, brings the shank in position to properly receive
the projected shank portion of the form D.
Having thus described my invention and its mode of operation I desire to say.
that, while shown in the drawings as associated with a sole laying machine
involving a rotary carrier, certain features of the present invention are broadly
novel and are not limited to their application to the specific machine shown, since
with slight modifications involving no departure therefrom they could be readily
adopted to other forms of sole laying, or sole levelling machines, not involving a
rotary carrier.

Improvements in Sole Laying Machines, in part also applicable to
Sole Levelling Machines.
A communication from abroad by THE GOODYEAR SHOE MACHINERY COMPANY,
of Boston, Massachusetts, United States of America.
I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I. Mech. E., of Norfolk House,
Victoria Embankment, London, W.C., Chartered Patent Agent, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The present invention relates to improvements in machines of the above class
and consists of certain improved mechanism for relatively actuating the jacks and
forms, operating automatically and successively to seat the forms, and bring
the jacks and forms into a position of pressure, of connections between said
mechanisms, whereby the operation of the jack seating mechanism, automatically
adjusts the pressure mechanism to the height of the shoe upon the sole of which
the form is seated; of improvements in the construction and arrangement of the
jacks and forms; and of the improved devices and combination of devices as
hereinafter more specifically set forth and claimed.
The object of the present invention is to increase the capacity and accuracy of
operation of machines of the above designated class, and to eliminate as far as
practical therein the liability of injury to the shoe or its last.
The present invention is illustrated in the drawings left with the Provisional
Specification, in which
Figure 1 is a front elevation of a machine embodying the same, with portion of
one of the cams removed to show underlying parts,
Figure 2 is a section on line x, x Figure 1,
Figure 3 is a rear view (enlarged) of a portion of the carrier, and portions
of mechanism for seating the form and securing pressure between the form and
jack.

mechanism for securing pressure between the jacks and forms.
Figure 5 is a side view of said mechanism, portions of the carrier being shown in
section on line y, y, Figure 3.
Figure 6 is a detached view of cam actuating the mechanism for securing
pressure.
Figure 7 is a top plan view of one of the jacks,

carrier,
Figure 9 is a partial rear view illustrating the stopping and starting mechanism,
Figures 10, 11 and 12 are detail views of one of the pressing forms.
Similar letters and figures of reference refer to similar parts throughout the
several views.
In the drawings A represents a frame suitable to support the working parts of
the machine.
In practice I construct the frame A, with a suitable base a, to which are secured
the standards a¹ and a³, the frame A may be however of any other suitable
form.
In the frame A is mounted a suitable rotary carrier, conveniently in the form of
a spider frame B, which is arranged to receive a series of partial rotations, for the
purposes hereinafter described, stopping automatically, and being started at the will
of the operator.
A preferred, though by no means essential, form of mechanism for securing the
above result is shown in the drawing and described as follows:-
The spider frame B is rigidly secured to and rotates with a shaft b, which is
mounted and free to turn in suitable bearings in the standards a¹ and a² of the
frame A.
The shaft 6 is projected through its bearing in the standard a³, and back of the
standard a², carries a worm gear 6', which is engaged by a worm 62, on the shaft 63.
The shaft 6 is mounted in suitable bearings in the frame A, in which it is free to
rotate, and is conveniently driven by means of the usual pulley b. The pulley b
turns loosely about the shaft b³, and is connected therewith by a suitable clutch,
mechanism being provided at the control of the operator for engaging the
members of the clutch to cause the shaft 63 and pulley b' to rotate together, and
automatically operating mechanisms being provided, whereby the members of the
clutch are disengaged to stop the rotation of the shaft 6, and allow the pulley b' to
turn loosely thereon.
While the form of the clutch, above referred to, or of its actuating mechanism
in itself forms no part of the present invention, it may be desirable in this
connection to briefly describe the specific form shown and its connection with other
features of the machine.
The pulley, being as before stated free to rotate independently of the
shaft 6, is also arranged to slide along said shaft, and the inner face of its hub
is provided with a segmental slot (not shown), which is engaged by a pin 2,
upon a disk 3 which rotates with and is held from motion along the shaft b
(see Fig. 9).
Adjacent to the shaft 63 is a substantially parallel shaft 6, mounted in suitable
bearings in the frame A, or the brackets 4, 4, thereon, in which it is free to rotate
and slide longitudinally being guided and held in position thereby. On the shaft b³
is a sleeve 5, free to turn thereon, but held from movement along the same by
suitable collars. To the sleeve 5 is secured a fork or collar 6, which engages a
groove in the hub of the pulley . The shaft also carries a hent lever 7, which
turns therewith, and is held from motion along the same. The lever 7, by means
of a spring 8, secured to an arm 9, on the shaft, and to a fixed part of the machine,
or by some other suitable device, is normally held in such position that the upper
end thereof projects in the path of a series of stops or dogs 10, 10 etc. on the
gear b¹, the above described arrangement being such that as the gear b' is rotated,
B

page_text: one of the stops 10, coming in contact with the lever 7, moves it and the shaft b
ontward, and, by means of the collar 6, moves the pulley & outward, causing the
pin 2 to be withdrawn from the segmental slot in the hub of pulley 64, and allowing
the pulley to rotate independently of the shaft 6³.
At or near the lower end of the lever 7 is formed a socket 12, which receives the
upper end of a rod 14, the lower end of which rests in a socket 15, formed upon
the treadle, fulcrumed at 16 on the frame A, or the lever 7 may be otherwise
suitably connected with the treadle 66, so that a depression of the treadle 6 causes
the lever 7 to tip backward out of the path of the dog 10. When the lever 7 has
cleared the dog 10, a suitably placed spring 17, closes the clutch, causing the
shaft to rotate with the pulley 6, and the spring 8 again advances the lever 7
bringing its front end again into the path of the dogs 10.
The number and position of the dogs 10 will depend upon the number and
position of the jacks on the spider frame, in the form of my invention shown in the
drawings in which the spider frame is provided with four jacks at substantially
ninety degrees apart, I have used four dogs 10 (only two shown) at substantially
ninety degrees apart upon the gear b'.
Upon the carrier B are mounted a series of pressing forms D, D etc., and a series
of shoe supporting jacks E, F etc.
While any suitable pressing form can be used in combination with the mechanisms
herein described without any departure from the present invention, I have in
practice adopted a pressing form which is an improvement upon the form shown
and described in the U.S. Letters Patent No. 549471 issued to me November 5,
1895 which, in order that one skilled in the art may readily construct a machine
embodying my invention in the best form known to me, I will now describe in
detail.
The form D as shown in the drawings comprises a rigid bed d (Figures 10, 11
and 12) having the general longitudinal contour of the bottom of a last, and to
which is bolted or otherwise suitably secured a flexible pressing pad d.
The pressing pad d' is formed of a continuous block of rubber or other suitable
elastic material, and provided with a projected shank portion d2, and a reinforcing
strip d³, covering substantially the edge pressing portions of the pad, substantially
as shown in my said Letters Patent.
Between the shank portion d2 of the pad d' and the bed d is located the shank
block d', which bears upon the pad d' at the points d and de, upou opposite sides
of the shank, and adjacent to the base of the reinforcing strip d³.
Upon the bed d is formed a boss d in which is formed a chamber d', which
extends through the bed d. To the block d' is secured a stem d which is fitted to
the bore of a tubular threaded bolt do, which engages correspondingly threaded
bearings in the top of the boss d. Upon the stem d is a collar d, free to slide
thereon, and between which and the block d' is placed a coiled spring d". The
inner end of the bolt do bears upon the collar 2, the above described arrangement
being such that the block d is held in contact with the pad d' at the points a
and d by the action of the spring d", which may be regulated by moving the
collar d along the stem d', by turning the bolt do in its threaded bearing. When
pressure is applied the stem d moves along the bore of the bolt do to allow the
block d to be forced toward the bed d, the stem de acting to guide the block d' and
keep it in its proper position. The chamber d' is preferably enlarged at its base
to form a recess d which receives the upper portion of the block d', so that the
same will not when forced against the bed d, form a ridge across the form which
would be apt to mark the sole.
The advantages which I claim for a form constructed as above described are its
increased accuracy of operation particularly at the edge portion of the shank, thus
ensuring an evenly laid sole, and the absence of any ridge or projection in the
rigid parts thereof which would tend to mark or otherwise injure the sole.
The jacks E may also be of any suitable construction, I find however, in practice,
that a form of jack substantially similar to that shown in the drawings secures the

page_text: best results, partly on account of the ease and rapidity with which it can be
adjusted, but principally because it makes a point upon the shank portion of the
shoe a positive point for all sizes of shoes, thereby always bringing the shank
portion of the shoe under the same part of the form, a result of great importance
in connection with a form having a projected shank portion, as shown in the
drawings..
As shown in the drawings each of the jacks E comprises a toe rest e and a heel
support el, the bases of which are fitted to a dove tailed groove e in the base
plate e, both the toe rest e and heel support el being movable along the plate e³,
toward and away from each other. On the plate eis eccentrically pivotted a
lever e, in the longer arm of which is formed a slot e (see Figure 7) which is
engaged by a pin e, upon the toe rest e, or a suitable projection e' thereon.
In the shorter arm of the lever e is formed a slot es, which is engaged by a
pin e, secured to a projection e¹o, upon the heel support e'. The above described
arrangement is such that a movement of the toe rest e along the plate e causes
a movement of the heel support e' in an opposite direction and to a less extent,
and vice versa.
The relative length of the arms of the lever e, determines the relative movement
of the toe rest and heel support, and since there is a proportional variation in the
lengths of the several parts of a sole in the different sizes of shoes it is evident
that the lever e can readily be arranged so that the shank of a large shoe
will be brought to substantially the same position under the form as the shank of
a small shoe.
I am aware that in certain forms of sole machines it has heretofore been
proposed to so arrange the jack that the toe of the last is made a positive point
for all sizes, while in others the positive point is at the heel, or at the center,
but so far as I am aware of the art no jack has been heretofore provided
in which a point on the shank is made the positive point for all adjustments for
length.
The toe rest e and heel support e' as above arranged may be conveniently locked
in any desired position by means of a spring pressed pawl e", mounted upon the
toe rest e, and arranged to engage a series of notches el upon the plate e³.
In all machines embodying a rotary carrier and series of jacks and forms thereon,
there are three essential movements, first; a rotation of the carrier, second; a
relative movement of the jacks and forms from a position of clearance to a position
of pressure, and third; a movement of the jacks out of operative relation to the
forms, whereby they are presented to the operator in convenient position for the
removal or adjustment of work. I may say in this connection that the jacks and
forms are said to be in a position of pressure when their relative position is such
that the sole of a shoe upon a last, placed upon the jack, would be sufficiently
compressed against the form to properly perform the sole laying operation, and
that the jack and forms are said to be in a position of clearance when their relative
position is such that the jack can be moved, with a shoe thereon, away from the
form into a convenient position for the removal of a shoe therefrom.
Having hereinbefore described a preferred form of mechanism for rotating
the carrier, I will now describe a preferred form of mechanism whereby the
jacks and forms are moved relatively to each other to produce compression and
clearance.
In accordance with the present invention the relative movement of the jacks and
forms, from a position of clearance to a position of pressure, occurs in two steps,
the first step seating the form firmly on the sole of the shoe upon the jack, and the
second step bringing the form and jack into a position of pressure, that is, forcing
them together with sufficient pressure to successfully perform the sole laying
operation.
The advantage which I gain by dividing the relative movement of jacks and
forms as above explained is that I am thereby enabled to use a powerful positively
actuating mechanism for producing pressure which is automatically adjusted by the

page_text: seating of the form to the height of the last, and thus while securing great
pressure, to avoid any danger of injury to the last or shoe.
As shown in the drawing each of the forms D is supported by a swinging
lever F, which I have hereinafter called the form lever, and which is fulcrumed
at on one of the arms b7 of the spider frame B.
The lever F in practice consists of the substantially parallel arms f, f(sce
Fig. 8) united at one end and at the opposite end embracing a sleeve, upon the
spider arm 6'. A trunnion extending through both of the arms f, and the
sleeve secures the lever F to the spider arm 6' and leaves it free to operate as
hereinafter described. The form D is preferably secured to the lever F by a
trunnion, which is mounted in the arms f¹, f, and extends through a bearing d
in the boss. ds (see Fig. 10), leaving the form D free to tip longitudinally.
In practice the bearing d is located substantially over the center of the bed d,
and I have provided near each end of the bed d, a coiled spring f (see Fig. 10)
which bears against the bed d and a movable plate f. In the lever F are provided
thread bearings f, which receive the bolts f, the lower ends of which are fitted
to sockets in the plates fo. Each of the plates f has upon its under side a
circular boss 20 which engages one or more coils of the spring f, and prevents
the same from slipping from the plate. A similar boss, and for a similar purpose,
is formed upon the bed d.
The above described arrangement is such that by turning the bolts f', ', the
action of the springs, f, may be regulated as required, so that the longitudinal
tipping movement of form D is controlled by elastic adjustable stops, which is a
feature of considerable advantage in this class of machines.
As shown in the drawings the seating of each of the forms D is accomplished
by means of a spring H, which is secured to the lever F, and to the spider
frame B, conveniently at the points h and h.
To the standard a³ of the frame A, is bolted or otherwise suitably secured a
cam C the form of which will be hereinafter more fully described, and upon
the lever F is secured a cam roll c, or other suitable projection, which as the
spider frame B rotates engages the cam C, and raises the form D into a position
of clearance.
As the spider frame B is further rotated, the cam roll e leaving the cam C, the
spring H acting upon the lever F, brings the form D down upon the sole of a shoe
upon the jack Ĕ.
While it is preferable that the form should be firmly seated upon the sole by
the spring H, as above explained, it is not intended thereby to secure sufficient
pressure to perform the sole laying operation, although by increasing the strength
of the spring H, or by substituting therefor a series of springs, such operation can
be successfully accomplished upon many grades of work, and further mechanism
for securing pressure dispensed with.
I will now describe in detail the form of mechanism shown in the drawing by
which after the form is seated I secure the necessary amount of pressure to
properly lay the sole.
Reference being had more particularly to Figures 3, 4, 5 and 6 of the drawing,
R represents a link pivotally connected with the lever F, preferably adjacent to
its free end, and also pivotally connected with a reciprocating rod r, or a suitable
offset r fixedly secured thereon.
In practice
have provided a casing which is bolted or otherwise fixedly
secured to the spider frame B, and in which are provided bearings and (see
Figure 5) in which the rod r is free to reciprocate longitudinally being guided and
held in position thereby.
On the rod is a collar, free to slide along the rod r, and from which is
projected an arm, which is acted upon by a lever ', conveniently pivotted at
upon the spider frame B, and carrying a cam roll r, which works upon a cam R¹,
bolted or otherwise suitably secured to the standard of the frame A.
collar is supported by a suitably placed spring 10, which may conveniently
The

page_text: consist of a coiled spring surrounding the rod r, and bearing against the collar
and the offset, projected from the spider frame B. The rod r extends through
the offset and a bearing for the rod is provided therein.
The above described arrangement is such that the rod is free to slide through
the collar, until the lever is depressed by the action of the cam R' upon the
cam roll, but when the lever is depressed as above stated, acting upon the
arm it cramps the collar on the rod rand forces down said rod for the purposes
hereinafter stated.
When the shape of the cam R¹ permits the cam roll to approach the center
and thus relieve the pressure on lever 7, the collar is no longer cramped,
but the rod is again free to slide through the same and the collar is returned
to its original position by the action of the spring 10. Of course it is understood
that the collar has a comparatively short bearing on the rod r, and when power
is applied away from the rod, toward the end of the arm, the collar becomes
cramped or binds on the rod r, forming a positive and easily controlled clutch,
which is capable of sustaining great strain without danger of breaking or slipping.
To allow for the relative movement of the lever and the arm +, I have in
practice made the following provision:-
On the arm is a collar l, free to turn thereon, but held from movement
along the same. The collar is provided, upon opposite sides, with suitable
sockets which are engaged by the inner ends of the thread bolts, P, having
bearings in a link , which surrounds the collar 1.
From the link
is projected a cylindrical sten P, which is fitted to a sleevel,
on the lever 7. The stem is free to rotate in the sleeve 15, and is held in
position therein by a suitable collar . I would say that in practice, the motion
of the lever being on both sides of the center, the above described arrange-
ment with the common machine fits will allow sufficient play of parts, and is
simple and durable.
It is evident that when arranged as shown in the drawing, if the jacks E are
empty, the rod r, before pressure is applied will be moved downward through the
collar, by the action of the spring H, acting through the lever F and link R,
until the lever F rests upon the casing, or some other fixed portion of the
machine, and it is further evident that if, when the parts are in the position
above stated, the cam R is allowed to act upon the lever to further depress
the rod r, some part of the machine will be broken or strained.
To avoid the above stated difficulty I have provided what I have called a safety
device, and which as shown in the drawing consists of a stop R2 dependent
from the rod r, conveniently from the offset and which, before the lever F
comes in contact with any fixed portion of the machine, strikes the collar, and
depresses the same until the arm, acting upon the lever ', raises the cam
roll away from the cam R', so that it cannot be acted upon thereby. The above
described device will be again referred to, and its operation more clearly
explained, in connection with the description of the operation of the machine of
the drawing hereinafter given.
The mechanism hereinbefore described as associated with one of the forms being
substantially similar to that associated with each of the other forms, no further
description thereof is considered necessary herein.
I will now describe the mechanism shown in the drawings whereby the jacks are
moved out of operative relation to the forms.
From the bed plate of each of the jacks E, are projected the lugs n, n, in
which is fixedly secured a shaft n', having bearings in the projections n², n² on the
spider frame B. From the base plate e of each jack E is projected a fixed
arm n, the outer end of which (preferably provided with a cam roll) bears upon
a cam N, bolted or otherwise fixedly secured to the standard a' of the frame A.
A suitably placed spring preferably consisting of a coiled spring n', coiled about
the shaft n, and secured thereto and to the spider frame B, acts to throw the jacks
outward, and to keep the arm n³ in contact with the cam N.

page_text: In practice I make the cam N circular except at the top where a depression n³
is formed. The above described arrangement is such that as the spider frame B
rotates the arm n³ of each jack E, bearing against the cam N holds the jack in
a substantially vertical position under its form D, until the arm n³ falls into the
depression n of the cam N, when the spring n forces the jack out of operative
relation to its form, presenting it to the operator in convenient position for the
removal or adjustment of the work. A further rotation of the spider restores the
jack to its vertical position under the form.
In practice I have provided a shelf P, at the top of standard a³ of frame A,
which projects over the spider frame R, and affords a convenient and easily
accessible place for the operator to keep his soles while using the machine.
While the specific form of the several cams herein before referred to is by no
means an essential feature of the present invention, I will give a brief description
of the forms thereof as shown in the drawings, and which I have found in practice
to operate successfully.
The cam R' may conveniently be formed substantially as shown in Figure 6
with an outer circular portion 30, and an inner circular portion 31, connected
by the inclined portions 32 and 33. The cam R' is in practice secured upon the
standard a² with the inner circular portion at the top, and symmetrically arranged
with reference to the vertical diameter of the spider frame B.
The cam N may conveniently consist of a circular disk, with the depression no,
which, when the cam N is in place upon the standard al, is at the top of the cain,
and symmetrically disposed with reference to the vertical diameter of the spider
frame.
The cam C may conveniently be formed with a circular central portion 40, and
inclined end portions 41 and 42. When secured to the standard a² the cam C
is also symmetrically disposed with reference to the vertical diameter of the spider
frame.
The relative extent of the several portions of the cams above described will
be readily understood from the following description of the operation of the
machine.
Assuming the parts of the machine of the drawings to be in the position shown
in Figure 1, the upper form D being in a position of clearance, with its cam roll c
resting upon the circular portion 40 of cam C, and the jack E associated with
said form being out of operative relation thereto, with its arm n³ resting in the
depression n of the cam N, and the cam roll being upon the inner circular
portion of the cam R¹ so that the rod r is free to slide through the collar,
power being applied to the pulley 4, the operator having removed the finished
work and jacked the shoe to be operated upon, places the cemented sole in
position, and by depressing the treadle sets the spider frame B in rotation.
As the spider frame B rotates the arm n³, being carried out of the depression n°
onto the circular portion of the cam N, raises the jack E against the action of the
spring n', and brings it into operative relation to the form D. As soon as this is
done the cam roll c being carried down the inclined portion 42 of the cain C,
allows the spring H to depress the lever F until the form D is seated upon the sole
under the pressure of spring H. While the spring H has been seating the form D
on the sole it has also by means of the link R, been depressing the rod through
its collar. When the form D has been seated as above stated the rotation of
the spider frame B brings the cam roll onto the inclined portion 33 of the cam R,
and the lever being depressed cramps the collar on the rod r, and depresses
said rod and the form D until the cam roll has reached the outer circular
portion 30 of the cam R', when the form is in its position of maximum pressure.
It is to be noted in this connection that the mechanism for giving the final
motion of pressure to the form D is automatically adjusted for the height of each
last, and thickness of sole thereon, by the seating of the form, so that all lasts
whether high or low are subjected to an equal amount of pressure, a result of
greatest importance in machines of this class.

page_text: The form D continues in the position of maximum pressure until the rotation of
the spider frame B brings the cam roll around to the inclined portion 32 of the
cam R', when the lever is released, releasing the rod r, and the cam roll c
engaging the inclined portion 41 of the cam C, passes up onto the circular portion 40
of said cam, raising the lever F, and bringing the form D into a position of
clearance, when the arm n³ drops into the depression n° in the cam N, allowing
the spring n to throw the jack E out of operative relation to the form D, and the
rotation of the spider stops. When four jacks are used as in the machine of the
drawings the rotation of the spider frame B is stopped at every quarter turn
leaving, one form in position of clearance and its jack out of operative relation
thereto, while all the other jacks are under pressure. When a different number
of jacks is used a stop is made for each jack as above explained.
As the operation of the mechanisms associated with each form and jack are
substantially the same, the above description is regarded as sufficient.
It is of course understood that the operator removes the work from, and adjusts
new work upon, the jacks, successively, as they are thrown out of operative
relation to their forms.
Should any of the jacks be left empty, and the spider frame B set in rotation,
when the cam roll c reaches the inclined portion 42 of the cam C, the spring H
acts to depress the lever F as before described, but before the lever F comes in
contact with the casing, or any fixed portion of the machine, the stop R, strikes
against the collar, and depresses the same until the cam roll clears the
cam R', so that while the spider B is making its rotation the cam R' does not act
to further depress the rod r.
To adjust any of the jacks E, for any length of last, the operator disengages
the pawl e", and moves the toe rest e, until the toe rest e and heel support e are
in position to properly support the toe and heel of the last, which, without further
interference on the operator's part, brings the shank in position to properly receive
the projected shank portion of the form D.
Having thus described my invention and its mode of operation I desire to say,
that, while shown in the drawings as associated with a sole laying machine
involving a rotary carrier, certain features of the present invention are broadly
novel and are not limited to their application to the specific machine shown, since
with slight modifications involving no departure therefrom they could be readily
adapted to other forms of sole laying, or sole levelling machines, not involving a
rotary carrier.
