A communication from abroad by THE UNITED SHOE MACHINERY COMPANY, of
New Jersey, in the United States of America.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
The present invention relates generally to improvements in sole pressing
machines, including machines adapted to temporarily attach the out sole to
the lasted upper and insole, commonly called sole laying machines," and
machines adapted to operate upon the outsole after it has been permanently
attached to the lasted upper and insole or welt, commonly termed "sole leveling
machines.' The present invention consists of improved means for adjusting
the pressure mechanism for different heights of last or thickness of sole, whereby
such adjustment is effected automatically and the required pressure secured,
where the above conditions vary, without manual interference on the part of
the operator. The present invention consists further of improved means of
presenting the jacks to the forms, and of other improvements in the construction
and organization of the machine, and the several mechanisms embodied therein.
In the machine is a frame suitable to support the working parts also a pair
of shoe supporting jacks, conveniently provided with usual toe rest and heel
support.
The forms may be of any suitable construction.
For leveling turn shoes, however, while prefering to use a metallic form, I
find it desirable to retain the jack, or to use some other suitable device to sup-
port the wooden last, so that the leveling operation can be performed upon the
wooden last upon which the shoes are lasted. This is also a desirable feature
in beating out welted shoes, and is made practical in my present machine by
my improved means for adjusting the pressing mechanism which prevents undue
pressure where the thickness of sole and height of last varies, which is otherwise
liable to break the last.
To present the jacks to the forms and to bring them into a convenient posi-
tion for the adjustment of a shoe thereon, or its removal therefrom, the
machine is provided with suitable mechanism.
The jacks are mounted upon a jack carrier which consists of a plate or bar
of suitable length, adjacent to opposite ends of which the jacks are mounted.
The jack carrier is supported by a table, the upper surface of which is substan-
tially horizontal, the jack carrier sliding along the same when turned into and
out of position. From the center of the jack carrier is projected an arm
offset free to turn about a suitable bearing in the table or extension thereof.
The bearing is in front of a point mid way between the two jacks and the dis-
tance from the center of the bearing to the medial line of the jacks is half the
or

page_text: distance between the forms.
When the forms are arranged with their toe ends
away from the operator, and their medial lines substantially parallel, the jacks
are arranged upon the carrier substantially in line, and with their heel sup-
ports adjacent to each other. On the table are provided suitable stops so posi-
iioned that when the carrier is turned against the same, one of the jacks is in
proper position to co-operate with its form.
The pressure mechanism of the machine is a table free to reciprocate vertically
along suitable vertical guides arranged to guide and laterally support the same.
Upon the lower side of the table is fulcrumed the upper member of the toggle
lever the lower member of which is fulcrumed upon the vertically movable cross
head which is also movable along the guides. Upon the cross head are formed
two guides or bearings which receive the vertical rods, and through which
said rods are free to reciprocate being guided and held in position thereby. The
rods below the cross head carry a cross head, between which and the cross head
is interposed a coiled spring, the lower end of which bears upon the cross head
and the upper end upon a disk, upon which bears a bolt having a threaded bear-
ing in the cross head. By raising or lowering the bolt the initial compression
of the spring may be regulated. The rods are capped above the guides or bear-
ings to prevent them being drawn out when the head is raised.
The cross head, when the jacks are under pressure is arranged to bear upon
an adjustable rest or stop, which as shown consists of a suitable bolt having a
threaded bearing in a fixed head, secured to the frame and which by means of
the hand wheel may be raised or lowered by rotation in said bearings. Stops
are provided secured in the guides which limit the downward movement of the
table. When the table rests upon the stops, and the toggle is straightened,
the cross head will move downward until the cross head contacts with the stop
or rest, when the resistance of the spring will oppose further downward move-
ment of the cross head, and the table will therefore be raised, and if one of the
forms has been properly seated, the jacks and forms will be brought into their
position of pressure. It will be noted from the above that the function of the
adjustable stop is to regulate the amount of pressure secured, which is greater
or less as the cross head contacts with the stop earlier or later in its downward
movement.
The mechanism for operating the toggle lever is of the usual type.
The driving shaft of the machine rotates the main shaft by means of the gear
connections. The shaft carries a suitably timed cam, which, by means of the
connecting link, operates the toggle.
The pressure mechanism includes the forms, the jacks, and the mechanism
for raising and lowering the jacks, the movement of the forms is not a movement
of pressure but an adjustment whereby the pressure mechanism, prior to its
pressure movement, is adjusted for the height of last and thickness of sole to
be onerated upon. In other words, by the movement of the forms the pressure
mechanism is adjusted to exert, on shoes of different heighths of last or thick-
ness of sole, a substantially uniform pressure, the resiliency of which is regulated
by the bolt, and the amount of which is determined by the position of the stop.
The forms are mounted upon a vertically reciprocating head, free to recipro-
cate along suitable vertical guides in the frame.
To the head is secured a vertical rod projected through a bearing on the
frame in which it is free to reciprocate, being guided and held in position
thereby.
To a rod is secured a vertical rack with which meshes a segmental gear carried
upon one arm of a bell lever which is fulcrumed at its angle upon the frame,
and the other arm of which carries a roll arranged to be engaged by a periphery
cam carried by the shaft. The cam is so timed and arranged that, when the
machine is started with the jacks and forms in a position of pressure, after the
toggle has released, and a head has been unlocked the periphery cam will engage
the roll and raise said head to bring the forms into their position of clearance,

page_text: This shaft
and, when the machine is started from a position of clearance the periphery
cam will allow the head to fall by its own weight until one of the forms is
seated upon the sole of a shoe upon one of the jacks. The mechanism for lock-
ing the forms to withstand the upward pressure of the jacks, after a form has
been seated upon the shoe, is as follows:-The said head has mounted above it
in suitable bearings in the frame, a shaft which carries the cams.
also carries a segmental gear which meshes with a segmental gear, carried by
the swinging lever, fulcrumed on the frame. The swinging lever carries, below
its fulcrum, a cam roll which is arranged to be engaged by a periphery cam on
the shaft. Around said shaft is arranged a coiled spring, one end of which
engages one of the cams, and the other end a fixed portion of the frame so
that the resilient action of said spring tends to rotate the shaft to turn the cams
in a forward direction. The cams are so formed that when turned in a forward
direction they will contact with the head or a suitable bearing block thereon,
and lock the forms against upward movement. The cam is so timed and arranged
that as the pressure is released it will engage the cam roll, and, by means of
lever rotate the shaft to turn the cams in rearward direction, to cause them to
release the head and to allow it to be raised by the cam and its connections.
After a form is seated upon a shoe, the cam leaves the roll, and allows the spring
to impart a forward rotation to the shaft which turns the cams forward until
they bind upon the bearing block when the forward rotation of shaft ceases,
and the head is locked from upward movement by the cams. It will be noted
that the releasing movement of cams is positive, while their locking movement
is spring controlled, so that it automatically varies in extent to provide for
different elevations of the head, caused by differences in the height of the last
or thickness of sole of the shoe upon which the working form rests.
A suitable start and stop mechanism is arranged to stop the machine when
the jacks and forms are in their position of pressure, and also when they are
in a position of clearance, so that the jack carrying the shoe which has been
operated upon, can be thrown out and the other jack brought under the form
which co-operates therewith.
The start and stop mechanism may be a pulley which normally turns loosely
upon the driving shaft and is free to have a limited sliding motion along the
same. The pulley is locked to this shaft to rotate therewith by means of a
clutch, one member of which turns with the pulley, being conveniently formed
upon the hub thereof, and the other member is keyed or otherwise secured to
rotate with the driving shaft. In the hub of the pulley is formed a circular
groove, which is engaged by a segmental flange, formed upon a hub carried by
the sliding shaft. The shaft is mounted to slide longitudinally and rotate in
suitable bearings in the frame. One of the gears referred to as conveying
the rotations of the driving shaft to the main shaft carries two projections or
dogs, which as the gear is rotated are arranged to engage a dog on the sliding
shaft, and to slide said shaft in its bearings sufficiently to disengage the members
of the clutch, and allow the pulley to turn loosely upon the driving shaft. A
treadle is provided which is connected with the sliding shaft by means of a
rod, which connects with an arm secured to said shaft, whereby the said shaft
may be rotated to turn the dog out of the path of the projections referred to
and to permit the spring, surrounding said shaft to slide it in its bearings to
close the clutch. Said shaft is rotated in an opposite direction to restore the
dog to its original position by means of a spring, which connects the arm with
a fixed portion of the frame.
Assuming that the jacks and forms are in their position of clearance, the
operator adjusts a shoe upon one of the jacks, and, having by means of the
bolt and the adjustable stop adjusted the pressure mechanism to secure the
desired resiliency and pressure, turns the jack carrier until it contacts with the
stop, which brings the jack under its co-operating form.
The operator then starts the machine by means of the treadle, and the head

page_text: drops by its own weight until the form rests upon the sole of the shoe which
has been placed on the jack. The seating of the form as above stated stops any
further downward motion of the head, and the cams are thrown forward and
lock it in its seated position against upward movement. After the form has
been seated and locked as above stated, the toggle is straightened and raises
the table and with it the jack carrier and jacks, the jack which is under the
form being brought into a position of pressure, and the sole of the shoe thereon
being compressed between the jack and form. At this time the jack at the
other end of carrier is out from under the forms and in a convenient position for
the removal of a shoe therefrom or the adjustment of a shoe thereon, and the
machine is automatically stopped. As soon as the operator has adjusted a shoe
upon the empty jack, he again starts the machine, and the toggle thereupon
releases the table to relax the pressure, the cams are turned back to unlock the
forms, and said forms are raised until the jacks and forms are in their position
of clearance, when the machine again stops. The operator then turns the carrier
until it contacts with the other stop, which bring the jack which has just
received its shoe under its co-operating form, and the jack with the shoe last
operated on into convenient position for removal of a shoe therefrom, and the
operator after adjusting a shoe in the empty jack again repeats the operation.

communication from THE UNITED SHOE MACHINERY COMPANY, of New Jersey,
in the United States of America.
I, ALFRED GEORGE BROOKES, of 55 & 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly des-
cribed and ascertained in and by the following statement:-
"
The present invention relates generally to improvements in sole pressing
machines, including machines adapted to temporarily attach the out sole to
the lasted upper and insole, commonly called sole laying machines," and
machines adapted to operate upon the outsole after it has been permanently
attached to the lasted upper and insole or welt, commonly termed "sole leveling
machines." The present invention consists of improved means for adjusting
the pressure mechanism for different heights of last or thickness of sole, whereby
such adjustment is effected automatically and the required pressure secured,
where the above conditions vary, without manual interference on the part of
the operator. The present invention consists further of improved means of
presenting the jacks to the forms, and of other improvements in the construction
and organization of the machine, and the several mechanisms embodied therein,
as more fully hereinafter pointed out in this specification and defined in the
claims.
The accompanying drawings illustrate my invention as applied to a sole
laying machine,
Figure 1 showing the same in side elevation,
Figure 2 in sectional elevation, portions of frame and pressure securing mech-
anism being removed,

page_text: Figure 3 in front elevation,
Figure 4 illustrating details of construction of start and stop mechanism, and
Figure 5 showing the machine in top plan.
In the several views of the drawings I have indicated like parts by like letters
of reference.
:
In the machine illustrated F is a frame suitable to support the working parts
hereinafter described. A, A, represent a pair of shoe supporting jacks, conven-
iently provided with the usual toe rest a and heel support a', the jack, however,
in itself, forms no part of the present invention, the specific form shown being
well known in the prior art, and requiring no further description herein.
The forms are shown at B, B, and may be of any suitable construction, in
practice I have found it desirable to use a form substantially similar in con-
struction of its essential features to that shown and described but good results
can be obtained with many other constructions of forms well known in the prior
art.
For leveling turn shoes, however, while prefering to use a metallic form,
1 find it desirable to retain the illustrated jack, or to use some other suitable
device to support the wooden last, so that the leveling operation can be per-
formed upon the wooden last upon which the shoes are lasted. This is also a
desirable feature in beating out welted shoes, and is made practical in my pre-
sent machine by my improved means for adjusting the pressing mechanism
which prevents undue pressure where the thickness of sole and height of last
varies, which is otherwise liable to break the last.
To present the jacks to the forms and to bring them into a convenient posi-
tion for the adjustment of a shoe thereon, or its removal therefrom, I have
provided in the machine of the drawings the following mechanism, which as
to certain features I consider to be novel and I will therefore describe in detail.
The jacks A, A, are mounted upon a jack carrier D), which as shown, consists
of a plate or bar of suitable length, adjacent to opposite ends of which the jacks
are mounted.
The jack carrier D is supported by a table, the upper surface of which is
substantially horizontal, the jack carrier D sliding along the same when turned
into and out of position as hereinafter described. From the center of the jack
carrier 1 is projected an arm or offset d, which is free to turn about a suitable
bearing, in the table 2, or a forwardly projected extension thereof. The
bearing is located immediately in front of a point mid way between the two
jacks B, B, and the distance from the center of the bearing to the medial line
of the jacks is half the distance between the forms B, B. When the forms B, B,
are arranged as shown with their toe ends away from the operator, and their
medial lines substantially parallel, the jacks A, A, are arranged upon the car-
rier substantially in line, and with their heel supports a adjacent to each
other (see Fig. 1). On the table are provided suitable stops 20 so positioned
that when the carrier D) is turned against the same, one of the jacks A is in
proper position to co-operate with its form.
The pressure mechanism of the machine of the drawings is described as
follows:
The table is free to reciprocate vertically along suitable vertical guides d³,
arranged to guide and laterally support the same. Upon the lower side of the
table d² is fulcrumed the upper member of the toggle lever, the lower member
of which is fulcrumed upon the vertically movable cross head, which is also
movable along the guides . Upon the cross head are formed two guides or
bearings do, which receive the vertical rods d, and through which said rods are
free to reciprocate being guided and held in position thereby. The rods d,
below the cross head d, carry a cross head between which and the cross
head is interposed a coiled spring d', the lower end of which bears upon the
cross head and the upper end upon a disk do, upon which bears a bolt d",
having a threaded bearing in the cross head d. By raising or lowering the

page_text: bolt the initial compression of the spring may be regulated. By initial
compression as I have used the term above, I desire to be understood as meaning
the extent of compression of the spring before any compressing action between
the jacks and forms occurs, it of course being understood that variations in
such initial compression effect proportionate variations in the force required to
further compress the spring when the jacks A are under pressure, and make
their compressing action more or less resilient or yielding. The rods are
capped above the guides or hearings to prevent them being drawn out when
the head d³ is raised.
The cross head 8 when the jacks A, are under pressure is aanged to bear
upon an adjustable rest or stop 12, (see Fig. 2) which as shown consists of a
suitable bolt having a threaded bearing in a fixed head 14, secured to the
frame F, and which by means of the hand wheel 5 may be raised or lowered
by rotation in said bearings. Stops 16 are provided (see dotted lines Fig. 3),
secured in the guides ³, which limit the downward movement of the table d².
The above described arrangement is such that when the table & rests upon the
stops, and the toggle is straightened, the cross head d³ will move down-
ward until the cross head contacts with the stop or rest d2, when the resist-
ance of the spring will oppose further downward movement of the cross head d³,
and the table will therefore be raised, and if one of the forms B has been
properly seated, the jacks and forms will be brought into their position of pres-
sure. It will be noted from the above that the function of the adjustable stop d¹³
is to regulate the amount of pressure secured, which is greater or less as the
cross head contacts with the stop d¹ earlier or later in its downward move-
ment.
The mechanism for operating the toggle lever d is of the usual type, and a
brief description thereof will be sufficient herein.
The driving shaft of the machine is shown at E, and rotates the main shaft E',
The shaft E carries a suitably
by means of the gear connections e and c¹.
timed cam 2, provided with the cam groove ex, which, by means of the cam
roller mounted upon the connecting link 3, operates the toggle . As shown
one end of the link e is pivotally connected with the central joint or knuckle,
of the toggle d and the other end of the link e³ is slotted to embrace the shaft E¹
which affords a support therefor.
In the machine of the drawings the pressure mechanism includes the forms B,
the jacks A, and the mechanism for raising and lowering the jacks as above
described, the movement of the forms which I will now describe is not a move-
ment of pressure but an adjustment whereby the pressure mechanism, prior to
its pressure movement, is adjusted for the height of last and thickness of sole
to be operated upon. In other words, by the movement of the forms the pres-
sure mechanism is adjusted to exert, on shoes of different heights of last or
thickness of sole, a substantially uniform pressure, the resiliency of which is
regulated by the bolt d, and the amount of which is determined by the position
of the stop 18.
The forms B, B are mounted upon a vertically reciprocating head b, free to
reciprocate along suitable vertical guides b₁ in the frame.
To the head b is secured a vertical rod 62 (see Fig. 2), which is projected
through a bearing 63 on the frame F, in which it is free to reciprocate, being
guided and held in position thereby.
To the rod 62 is secured a vertical rack b', with which meshes a segmental
gear 65, carried upon one arm of a bell lever 66, which is fulcrumed at its angle
upon the frame F, and the other arm of which carries a roll 67, arranged to be
engaged by a periphery cam 68, carried by the shaft E¹. The cam 68 is so timed
and arranged that, when the machine is started with the jacks and forms in a
position of pressure, after the toggle has released, and the head 6 has been un-
locked as hereinafter described, the cam 8 will engage the roll 67 and raise the

page_text: head b to bring the forms B into their position of clearance, and, when the
machine is started from a position of clearance the cam 68 will allow the head b
to fall by its own weight until one of the forms B is seated upon the sole of a
shoe upon one of the jacks A. The mechanism for locking the forms B to with-
stand the upward pressure of the jacks, after a form has been seated upon the
shoe, is described as follows:-Above the head b, mounted in suitable bearings
in the frame F, is a shaft c, which carries the cams c¹, c¹. The shaft c also car-
ries a segmental gear 2, which meshes with a segmental gear, carried by
the swinging lever c, fulcrumed at on the frame F. The swinging
lever carries, below its fulcrum, a cam roll , which is arranged
to be engaged by a periphery cam on the shaft E¹. Around the shaft c is
arranged a coiled spring 8, one end of which engages one of the cams c¹, and the
other end a fixed portion of the frame F, so that the resilient action of said
spring tends to rotate the shaft c, to turn the cams in a forward direction.
The cams care so formed that when turned in a forward direction they will
contact with the head b, or a suitable bearing block 65 thereon, and lock the
forms against upward movement. The cam c is so timed and arranged that as
the pressure is released it will engage the cam roll e, and, by means of lever c',
rotate the shaft c to turn the cams c in rearward direction, to cause them to
release the head b, and to allow it to be raised by the cam 68 and its connections.
After a form is seated upon a shoe, the cam c' leaves the roll 6, and allows the
spring to impart a forward rotation to the shaft c, which turns the cams c¹
forward until they bind upon the bearing block 15, when the forward rotation
of shaft c ceases, and the head is locked from upward movement by the cams c¹.
It will be noted that the releasing movement of cams c¹ is positive, while their
locking movement is spring controlled, so that it automatically varies in extent
to provide for different elevations of the head b, caused by differences in the
height of the last or thickness of sole of the shoe upon which the working form
rests.
In connection with the mechanism heretofore described I have provided in
the machine of the drawings a suitable start and stop mechanism, which is
arranged to stop the machine when the jacks and forms are in their position
of pressure, and also when they are in a position of clearance, so that the jack
carrying the shoe which has been operated upon, can be thrown out and the
other jack brought under the form which co-operates therewith.
The start and stop mechanism illustrated consists of pulley e, which normally
turns loosely upon the driving shaft E, and is free to have a limited sliding
motion along the same. The pulley et is locked to shaft E to rotate therewith
by means of a clutch e, one member of which turns with the pulley, being
conveniently formed upon the hub thereof, and the other member is keyed or
otherwise secured to rotate with shaft E. In the hub of the pulley e is formed
a circular groove e, which is engaged by a segmental flange e', formed upon
a hub carried by the shaft es. The shaft 8 is mounted to slide longitudinally
and rotate in suitable bearings in frame F. The gear e¹ carries two projections
or dogs e (only one shown) which are arranged, as the gear e¹ is rotated to engage
a dog elo on the shaft c8, and to slide said shaft in its bearings sufficiently to dis-
engage the members of the clutch, and allow the pulley to turn loosely upon
the shaft E. A treadle e2 is provided which is connected with the shaft by
means of a rod 20, which connects with an arm 2, secured to the shaft (8,
whereby the shaft may be rotated to turn the dog et out of the path of the
dog e, and to permit the spring e, surrounding the shaft es, to slide the shaft e
in its bearings to close the clutch. The shaft is rotated in an opposite
direction to restore the dog e¹0 to its original position by means of a spring e,
which connects the arm with a fixed portion of the frame F.
It is perhaps unnecessary to add that the stop mechanism above described
forms no essential part of the present invention, and there are many forms of

page_text: such mechanism in the prior art whereby equally good results could be
secured.
The forms B, as shown, are removably and adjustably secured to the head b
as is usual in this class of machines.
The operation of the machine of the drawings is as follows:-
Assuming that the jacks and forms are in their position of clearance, the
operator adjusts a shoe upon one of the jacks, and, having by means of the
bolt d and the adjustable stop 2 adjusted the pressure mechanism to secure
the desired resiliency and pressure, turns the jack carrier ]) until it contacts
with the stop d, which brings the jack A under its co-operating form B.
The operator then starts the machine by means of the treadle e, and the
head drops by its own weight until the form B rests upon the sole of the shoe
which has been placed on the jack A. The seating of the form as above stated
stops any further downward motion of the head b, and the cams are thrown
forward and lock it in its seated position against upward movement. After
the form has been seated and locked as above stated, the toggle is straightened
and raises the table and with it the jack carrier D and jacks A, the jack A
which is under the form B being brought into a position of pressure, and the
sole of the shoe thereon being compressed between the jack and form. At this
time the jack A, at the other end of carrier D, is out from under the forms B,
and in a convenient position for the removal of a shoe therefrom or the adjust-
ment of a shoe thereon, and the machine is automatically stopped. As soon as
the operator has adjusted a shoe upon the empty jack, he again starts the machine,
and the toggle thereupon releases the table to relax the pressure, the cams e¹
are turned back to unlock the forms B, and said forms are raised until the
jacks and forms are in their position of clearance, when the machine again
stops. The operator then turns the carrier D, until it contacts with the other
stop 20, which brings the jack which has just received its shoe under its co-
operating form, and the jack with the shoe last operated on, into convenient
position for removal of a shoe therefrom, and the operator after adjusting a
shoe in the empty jack again repeats the operation herein before described.
I desire to say that I am aware that it has heretofore been proposed in sole
leveling machines to mount the jacks on a rotary carrier, but such carrier has
never before, in so far as I am advised of the state of the art, been set off from
its center of rotation, and it has heretofore been necessary where the jacks were
brought in front of the machine to rotate the jacks upon the carrier in order
that they might be properly presented to the forms and the operation.
By setting off the carrier from its rotation as hereinbefore described, while
presenting the jacks successively at the front of the machine, I avoid this neces-
sity of turning the jacks themselves, thereby greatly increasing the speed and
efficiency of the machine.
In a known construction of sole laying machine I am aware that provision
has been made for an adjustment of the pressure mechanism for lasts of different
heights and soles of different thickness, but it is to be noted that the mechanism
of such a machine differs from that of my present machine as to this feature
in that in such known machine the seating movement of the "form" is continued
<< form " is in
for the pressure movement, and the seating mechanism for the
operative connection with the pressure mechanism, said seating mechanism act-
ing to shift or vary the point of connection between the form and the pressure
mechanism. In the present invention the seating movement of the
is entirely independent of the movement which produces pressure and there is
no connection between the form and pressure securing mechanism.

Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is -
1. In a sole pressing machine, the combination with a jack and form, of inde-

page_text: pendent mechanisms operating automatically and successively to seat the form
and to bring the form and jack into a position of pressure, substantially as
described.
2. In a sole pressing machine, the combination with a form member and a
