Improvements in Sole Laying and Pressing Machines for Boots
and Shoes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates, particularly, to machines for pressing cement-coated outer
soles against lasted uppers of boots and shoes, and holding the soles against the
uppers while the cement is setting or hardening.
The invention consists in certain improved mechanism for jacking the shoe by
hand and also for applying power to press the shoe sole against the upper, after it has
been "jacked."
The invention further consists, in certain improvements in the jack, or holder, for
the lasted boot or shoe whereby the same may be quickly and easily adjusted to
conforin to various sizes and shapes of lasts.
The machine comprises side standards or frames, which serve to support the
working parts of the machine, a lower and an upper cross-head, and a middle cross-
head the lower cross-head being connected to the upper cross-head by stay-rods.
The stay-rods are clamped to the standards and are fastened to the middle cross-head.
The upper cross-head is formed with turrets to receive flexible pressers or forms,
said pressers being of any suitable construction.
The driving-shaft rotates in bearings in the lower cross-head. At one end of the
driving shaft is a pulley which rotates loosely upon the driving shaft and is provided
with a conical face adapted to engage a conical face upon a clutch pulley. The clutch
pulley is fast to the driving shaft and is encircled by a brake or friction strap.
The loose pulley is forced lengthwise of the driving shaft into contact with the
clutch pulley, or out of contact therewith by mears of the collar, a screw-threaded
sleeve, and a nut. The nut is connected by a link to an arm which arm is fast to a
rock-shaft. The said rock-shaft has bearings in the lower cross-head and in a bracket
which is fastened to the floor.
A treadle is fast to the rock-shaft, and is provided with a friction-roll, which turns
on a pin or stud in a sliding-pin, which fits in a recess formed in the treadle and is
pushed upwardly against a cam by a spring. A cross-pin prevents the sliding pin
from turning in the treadle.
Upon the driving-shaft is a pinion-gear which meshes with a gear affixed to a
erank-shaft having bearings in the lower cross-head. Upon the crank-shaft are
formed two cranks, at an angle of 180 degrees with each other.
The cranks are in line with the centre line of the turrets and each receives and
imparts motion to a jack. Each jack comprises two last supporting standards, one of

page_text: which is provided with a spring-pin and supports the heel portion of the last while
the standard provided with a toe-piece to support the toe of the same, the toe-
piece being adjustable vertically to conform to varying shapes and sizes of lasts.
The last-supporting standards are each formed with a rectangular base dovetailed
to fit a groove or guide in a rectangular slide-block. Upon each of the standards is
fastened a rack which meshes with a gear, the racks being upon opposite sides of the
gear. The gear is fast to a spindle and is turned by means of a hand-wheel. The
spindle has a bearing in a bracket, which is fastened by screws to the slide-block. It
is evident that by turning the handle, the gear will be rotated and the standards will
be caused to approach or recede from each other, in order to fit varying sizes of lasts.
When the standards have been brought to the desired distance from each other, they
are locked in position by a set-screw.
The slide-block is formed to slide in horizontal ways upon the upper end of a
vertical slide, said slide being guided in ways upon a swinging arm, the lower end of
which is attached to one of the cranks by a cap. The slide is moved up or down
upon the swinging arm by a lever and an arm, which are pinned to the rock-shaft,
said rock-shaft having bearings on the swinging arm and are connected to the slide
by links. The lever is locked in position by a spring pawl which engages a rack, fast
to the arm on the rock-shaft. A guide-roll upon the slide engages a groove upon
the middle cross-head when the swinging arm is in a vertical position and the slide is
raised. When the slide is lowered, the roll passes out of the groove and the swinging
arm may then be tipped forward upon the crank, as hereinafter explained,
The operation of the machine as a whole is as follows: The swinging arın being
suitably tipped, the operator places the cement covered shoe thereon, he then places
the outer sole upon the shoe in its proper location, and pushes the arm into a vertical
position on the left hand side of the machine, the operator holding the arm in
position with the left hand pushes down upon the handle of the slide-operating lever
with the right hand, thus raising the shoe, bringing the shoe sole against the presser
by means of the links, and locking it in position by the pawl and rack. When in this
position, the link and the short arm of the slide-operating lever form a toggle-joint so
that when the last is raised, the link and the short arm of the lever approach a
straight line joining the points at which they are pivoted to the slide and the
swinging arm respectively. It will thus be seen that the shoe can be firmly pressed
against the presser-pad by a comparatively slight pressure upon the end of the long
arm of the slide operating lever.
Having "jacked" the shoe as described, the operator depresses the treadle, thus
forcing the conical face of the loose pulley against the conical face of the clutch
pulley, by means of the rock-shaft, arm, link, nut, sleeve and collar. The friction
strap is at the same time released by means of the arms fast to the rock-shaft, their
outer ends being secured to the strap.
When the treadle is depressed the cam roll is withdrawn from the depression in
the cam until the periphery of the roll nearly clears the outer periphery of the cam.
The loose pulley through the clutch turns the driving shaft and through the gears
the crank shaft is rotated, forcing one of the swinging arms with its last and shoe
upward against its corresponding presser-pad and lowering the other arm and releasing
it from the pressure applied by power. The shoe which is released is then lowered still
farther by unlocking the pawl and raising the outer end of the slide-operating lever
until the guide-roll clears the groove when the operator pulls the swinging arm
toward him, tipping said arm upon the crank, the arm being stopped at this point
from falling forward by the link which is pivoted to the swinging arm and encircles
the stay-rods, a collar upon one of the stay-rods serving to hold up the link.
When the swinging arm is brought forward, and while the shoe upon the other
arm or jack is under pressure, the operator removes the shoe from the jack which is
tipped forward, places another thereon and repeats the above described operation.
The clutch is automatically thrown out and the rotation of the machine stopped
by the cam, as follows: As soon as the operator has lowered the treadle until the
clutch is thrown in as described, the cam turns and locks the treadle down and the

page_text: clutch in, until another depression upon the cam, located at 180 degrees from the first
depression, comes opposite the cam roll, when the spring on the treadle raises the
same and the roll enters the depression in the cam, throwing out the clutch and
applying the friction brake or strap to overcome the momentum of the machine. In
order to keep the clutch firmly pressed together and to allow for slight variations due
to wear, the roll does not quite clear the outer periphery of the cam when the operator.
depresses the treadle, so that when the cam is turned by the clutch the roll is pressed
down compressing the spring and holding the clutch firmly in place until the roll comes
opposite the next depression in the cain as described.

Improvements in Sole Laying and Pressing Machines for Boots
and Shoes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
This invention relates particularly to machines for pressing cement-coated outer
soles against lasted uppers of boots and shoes, and holding the soles against the uppers
while the cement is setting or hardening.
The invention consists in certain improved mechanism for jacking the shoe by
hand, and also for applying power to press the shoe-sole against the upper after it has
been "jacked."
The invention further consists in certain improvements in the jack or holder for
the lasted boot or shoe, whereby the same may be quickly and easily adjusted to
conform to various sizes and shapes of lasts.
Referring to the accompanying drawings, forming a part of this specification,-
Figure 1 is a front elevation of my improved sole-laying machine, one of the jacks
being shown raised and the other depressed.
Figure 1 is a detail view of the crank-shaft.
Figure 2 is a side elevation of the machine, one side of the supporting frame being
removed in order to more clearly illustrate the mechanism.
Figure 3 is an enlarged plan, partly in section, taken on line 3-3 of Figure 1.
Figures 4 and 5 are detail elevations, illustrating the guide-roll of the jack-carrying
arm in different positions.
Figure 6 is a section on line 6-6 of Figure 2.
Figure 7 is an enlarged end elevation of my improved jack.
Figure 8 is a longitudinal section of the jack, taken on line 8-8 of Figure 7.
Like letters refer to like parts, throughout the several figures of the drawings.
In the drawings, forming a part of this specification, a a represent side standards
or frames which serve to support the working parts of the machine. The lower
cross-head is connected to the upper cross-head c by the stay-rods d d. The
stay-rods d d are clamped at a¹ a¹ to the standards a a, and are fastened at el e¹ to
the middle cross-head e.. The cross-head c is formed with turrets c¹ c¹ to receive
flexible pressers or forms c² c², said pressers being of any suitable construction.
The driving-shaft b¹ rotates in bearings 62 62 in the cross-head b. At one end of
the shaft b¹ is a pulley 63. Said pulley rotates loose upon the shaft b', and is provided

page_text: with a conical face 6* adapted to engage the conical face 65 upon the clutch-pulley be.
The pulley 6 is fast to the shaft b', and is encircled by a brake or friction-strap 6'.
The pulley 63 is forced lengthwise of the shaft b¹ into contact with the clutch-
pulley b, or out of contact therewith, by means of the collar 68, screw-threaded
sleeve, and nut 610. The nut 610 is connected by the link b¹ to the arm b¹², said
arm 612 being fast to the rock-shaft 13. The rock-shaft 613 has bearings at 614 614 in
the lower cross-head b, and in the bracket 615, said bracket being fastened to the
floor.
.
The treadle 616 is fast to the rock-shaft 13, and is provided with a friction-roll b",
which turns on a pin 618 in a sliding pin 61. The sliding pin 19 fits in a recess
formed in the treadle 610, and is pushed upwardly against a cam 27 by the spring 620,
a cross-pin 621 preventing the pin 619 from turning in the treadle 61.
Upon the driving-shaft is a pinion-gear 622, which meshes a gear 623. Said gear
is fast to a shaft 6 having bearings at 65 625 in the cross-head b. Upon the
shaft b4 are formed two cranks 620 620 at an angle of one hundred and eighty degrees
with each other.
The cranks 620 626 are in line with the center line of the turrets c¹ c¹, and each
receives and imparts motion to a jack. Each jack comprises two last-supporting
standards ff. The standard f is provided with a spring-pin f2, and supports the
heel portion of the last. g. The standard f1 is provided with a toe-piece f³ to support
the toe of the same, the toe-piece being adjustable vertically to conform to varying
shapes and sizes of lasts.
The standards f f¹ are each formed with a rectangular base f dovetailed to fit a
groove or guide in the rectangular slide-block f. Upon each of the standards f f¹ is
fastened a rack fe, which meshes a gear f, the racks being upon opposite sides of the
gear. The gear is fast to a spindle f, and is turned by means of a hand-wheel ƒ³.
The spindle has a bearing in the bracket f10, said bracket f10 being fastened by
screws to the slide-block f. It is evident that by turning the handle f the gear f
will be rotated, and the standards f f¹ will be caused to approach or recede from each
other, in order to fit varying sizes of lasts. When the standards have been brought
to the desired distance from each other, they are locked in position by the set-
screw f¹¹
The slide-block is formed to slide in horizontal ways upon the upper end of
a vertical slide f14. Said slide 14 is guided in ways f15 upon a swinging arm f16, the
lower end of which is attached to the crank 626 by the cap f17. The slide fi is moved
up or down upon the arm f18 by the lever f18 pivotted at 10, in bearings flf on the
arm fl, and being connected to the slide 14 by the links f22 f22. The lever f18 is
locked in position by the spring-pawl f23, which engages the rack f24 fast to the arm 20.
A guide-roll upon the slide 14 engages a groove 2 upon the cross-head e when the
arm 16 is in a vertical position and the slide f" is raised, as shown in Figures 2 and 5.
When the slide f¹ is lowered, the roll f25 passes out of the groove e, and the arm fie
may then be tipped forward upon the crank 620, into the position shown in dotted
lines in Figure 2, as hereinafter explained.
I do not wish to be understood as claiming anything new in this manner of guiding
the arm 18 and slide f¹; and so far as the practical operation of the machine is
concerned, the guide-roll f5 and groove e2 may be dispensed with. In a machine so
constructed, it would only be necessary to allow the lug to which the roll f25 is fastened
to bear against a straight surface or open guide-way upon the frame of the
machine.
The operation of the machine as a whole is as follows: The arm 1 being tipped
out in the position shown by dotted lines (Figure 2), the operator places the cement-
covered shoe thereon. He then places the outer sole upon the shoe in its proper
location, and pushes the arm into a vertical position, as shown in Figure 1, on the
left-hand side of the machine. The operator holding the arm in position with the
left hand, pushes down upon the handle of the lever 18 with the right hand, thus
raising the shoe to the position shown in Figure 2 and in the right-hand side of
Figure 1, bringing the shoe-sole against the presser c², by means of the links f22, and
:

page_text: locking it in position by the pawl f23 and rack 24. When in this position, it will be
observed that the link f22 and the short arm of the lever f18 form a toggle-joint, so
that when the last is raised in the position shown in Figure 2, the link and the short
arm of the lever approach a straight line joining the points at which they are pivoted
to the slide f and the swinging arm fe, respectively. It will thus be seen that the
shoe can be firmly pressed against the presser-pad c² by a comparatively slight
pressure upon the end of the long arm of the lever f18
Having "jacked" the shoe, as described, the operator depresses the treadle 616,
thus forcing the conical face of the pulley b against the conical face of the clutch-
pulley 66, by means of the rock-shaft 613, arm 612, link 611, nut 610, sleeve 6º, and
collar 68. The friction-strap is at the same time, released by means of the
arms 628628 fast to the rock-shaft 613, their outer ends being secured to the strap 67.
When the treadle is depressed, the cam-roll 617 is withdrawn from the depression
in the cam 6 until the periphery of the roll nearly clears the outer periphery of the
cam. The pulley 3, through the clutch, turns the shaft 61, and through the
gears 663 the crank-shaft 24 is rotated, forcing one of the arms f¹ with its last and
shoe, upward against its corresponding presser-pad, and lowering the other arm and
releasing it from the pressure applied by power. The shoe which is released is then
lowered still farther by unlocking the pawl f23 and raising the outer end of the
lever 18 until the guide-roll f clears the groove e², when the operator pulls the
arm fi toward him, tipping said arm upon the crank 620 into the position shown in
dotted lines in Figure 2, the arm being stopped at this point from falling forward,
by the link 2, which is pivoted to the arm fie at f27 and encircles the
stay-rods dd, a collar f28 upon one of the stay-rods serving to hold up the
link 20.
When the arin fe is brought to the position shown in dotted lines in Figure 2,
and while the shoe upon the other arın or jack is under pressure, the operator
removes.the shoe from the jack which is tipped forward, places another thereon, and
repeats the above-described operation.
The clutch is automatically thrown out, and the rotation of the machine stopped
by the cam 627, as follows: As soon as the operator has lowered the treadle until the
clutch is thrown in as described, the cam turns and locks the treadle down and the
clutch in, until another depression upon the cam, located at one hundred and eighty
degrees from the first depression, comes opposite the cam-roll, when the spring b
on the treadle raises the same, and the roll enters the depression in the cam,
throwing out the clutch and applying the friction-brake or strap 67 to overcome the
momentum of the machine. in order to keep the clutch firmly pressed together,
and to allow for slight variations due to wear, the roll 17 does not quite clear the
outer periphery of the cam when the operator depresses the treadle, so that when
the cam is turned by the clutch, the roll 617 is pressed down, compressing the
spring 620, and holding the clutch firmly in place until the roll comes opposite the
next depression in the cam, as described.
