I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents,
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 has for its object to provide improved mechanism for securing uppers
to soles of turned shoes, by stitches or loops of thread passed through the upper and
through a portion of the sole and locked by tongues of leather cut in one of the sides
of the sole.
The invention consists in the several improvements which I will now proceed
to describe.
In the accompanying drawings.

Figures 21, 22, 23 and 24, represent perspective views showing different parts of
the loop or stitch forming mechanism.
The same letters of reference indicate the same parts in all the Figures above
referred to.
a represents the supporting frame mounted on a pedestal b, and having bearings
for the driving shaft c, which imparts motion to the operative parts of the machine.
d represents a back gauge or rest which is formed to support the lasted shoe at the
point where the needle passes through the upper, and has a slot e, through which
the needle passes; said slot being elongated so that the back gauge can move while
the needle is projecting through it. Said back gauge is supported by a swing
piece f, which is pivotted at g (Figures 1, 2, 3 and 4) to the frame of the machine
and is oscillated in a plane at right angles to the driving shaft by a cam h, on said
shaft; said cam rotating between two bearing surfaces, i, j, on the swing piece f
(see Figure 3). One of said bearing surfaces, j, is a roller mounted on a lever k which
is adjustable by a screw 1, to compensate for wear of the cam and bearing surfaces.
The back gauge is not attached directly to the swing piece ƒ but to a lever m
(Figures 5 and 6) which is pivotted at n to the swing piece f and is connected at its
upper end by a link o, with the lower end of a slide p which is fitted to reciprocate
vertically in a guide in the swing piece fand is reciprocated in said guide by a cam
groove in a disc on the driving shaft c, said slide having a studs entering
said groove.
t represents a depth gauge which is attached to a lever v, pivotted at u to an ear on
the swing piece f, and is formed to bear on the surface of the sole at a point close to
the margin and close to the point where the tongue forming knife and needle act on
the sole, and determine the height at which the shoe is held by the operator. The
upper end of the lever has a cam shaped slot, w (Figure 9) which receives the wrist
The vertical move-
pin a¹, of a crank 6, journalled in the lower end of the slide P.
ments of said slide oscillate the lever v and thus alternately raise and lower the depth
gauge and also oscillate the lever m, and move the back gauge d toward and away
from the work.
υ
c' represents a pointed feed dog, the shank or body of which is segmental and is
fitted to slide in a segmental groove d', in the swing piece (Figures 6 and 9). Said
dog is connected by a rod or link e¹, to the wrist pin a' of the crank in the lower
end of the slide p, so that the movements of said slide cause the dog to reciprocate or
oscillate in a curved path and alternately enter and leave the sole as hereinafter
described.
The crank is provided with a handle f" (Figures 2 and 9) by which the operator
can turn said crank to simultaneously raise or lower the depth gauge and feed dog as
occasion may require. The crank is prevented from rotating loosely by a spring g',
(Figure 8) which is coiled upon the crank and is attached at one end to the crank
and at the other end to a fixed support. The parts are so timed that when the
operator places the shoe against the back gauge while the needle is raised, the depth
gauge and feed dog are moved downwardly until the depth gauge bears on the sole
and the dog enters the latter, and presses the shoe against the back gauge, the latter
being moved by the lever 'm toward the work; after which the swing piece f is swung

page_text: in one direction by the cam h, causing the feed dog to feed the work, the dog and
depth gauge being then raised and the back gauge moved back from the work, which
is thus released before the swing piece f swings in the opposite direction to restore
the
gauges d, t, and dog c¹ to their starting position.
represents the tongue cutting knife which is a segmental piece of sheet metal,
V-shaped in cross section, and attached by a removable clamp (Figures 13 and 14)
to a lever j¹ which is mounted to oscillate on an oblique stud ¹, affixed to the
frame a.
The arrangement of said stud and lever is such that the knife oscillates in a plane
at an angle of about forty five degrees to the plane in which the needle moves, the
path in which the knife moves intersecting that in which the needle moves, so that
the knife in moving forward while the needle is raised cuts a tongue on the sole at
the point where the needle enters the sole and then moves back obliquely out of the
path of the needle. The needle afterwards descends and enters the incision last
formed by the knife and penetrates the between substance under said tongue, as
described hereinafter.
The lever j¹is oscillated by means of a cam groove 1, in a disc m² on the driving
shaft, a lever n' pivotted at to a fixed arm on the frame a, and having at its upper
end a stud entering said cam groove, and a rod p¹ connecting the lower end of said
lever n' with the knife carrying lever j¹.
represents the needle which is curved in the arc of a circle and has a barb on its
concave side. Said needle is clamped to an arm, which is pivotted at s¹ (Figures 2
and 15) to a fixed ear on the frame a and is connected by a link, t¹ with a slide u¹
(Figure 2) which is fitted to move in a vertical guide in the frame a, and is recipro-
cated in said guide by a cam groove in a disc v¹ on the driving shaft, the slide
having a stud w¹ (Figure 2) entering said cam groove. The needle is thus oscillated
and caused to alternately enter and leave the work.
62, represents the looper arm which is formed on a hub c² mounted to oscillate on a
stud attached to the lever m carrying the back gauge
d.
12
Said hub has another arm e², having an orifice which receives a fixed stud f, on
the frame a.
Said stud, when the swing piece is swinging backwardly to carry the
feed dog and gauges d, t, to their starting position (as above described) causes
the hub to partly rotate and thus move the looper arm sufficiently to cause it to throw
the thread carried by it into the barb of the needle when the latter is projected through the
work, as hereinafter described. The thread passes from the supplying spool to the
needle between adjustable tension plates g², g² (Figures 2, 11 and 12) on a stud h²,
affixed to the side of the frame a, from thence over a pulley 2, on the take up lever,
then back over a pulley 15, on the stud h², beside the tension plates g², g², and then
through the looper 62. The take up lever is pivotted at 2 to a fixed arm on the
frame a and has at its upper end a stud entering a cam groove 12, in the disc m². Said
lever is pressed by a spring m², in the direction indicated by the arrow in Figure 2,
its stud being thereby normally held in contact with one side of the cam groove
said spring being interposed between an arm n² attached to the frame a, and a nut o²,
on a rod p² attached to the lever and adapted to slide in an orifice in the arm n².
The cain groove 12 has a lateral enlargement at 2 (Figures 1 and 19) which comes to
the point where the stud of lever enters said groove, as shown in Figure 19, just as
the needle commences to draw the loop through the upper and sole and permits the
lever to yield, so that the tension of the spring m² is applied to the thread while it is
being pulled through the upper and sole and until the stitch is drawn closely against
the surface of the upper. After this the offset portion 3, of the cam groove moves the
lever to the position shown in Figure 20 causing it to loosen the thread while
the needle is completing the drawing out of the loop and while the loop is being cast
off from the barb of the needle, after which the main portion 4, of the cam groove
moves the lever to the position shown in Figure 2, causing it to suddenly take up
the loop and draw it tightly over the tongue on the sole.
q² represents the loop spreader which enters and spreads the loop preparatory to
the separation of the same from the barb of the needle by the cast off. Said spreader

page_text: is a curved arm having a longitudinal slot into which the cast off swings in separating
the loop from the barb of the needle, as presently explained. The spreader is attached
to a slide 2, which is fitted to reciprocate in a guide in a lever s2, which is pivotted
at t² to a fixed ear on the frame a, and has its upper end engaged by a stud u² with a
cam groove v² in a disc w² on the driving shaft, the lever 82 being thus oscillated and
caused to oscillate the loop spreader toward and from the needle. The spreader has,
in addition to this oscillating movement, an up and down movement caused by the
engagement of the slide 2 by a link a³, with a slide 63 (Figures 17 and 18) which is
fitted to slide vertically in a guide in the frame a, and has a stud c³ which is engaged
with a cam groove, d³, in the inner side of the disc w².
The cast off es is a bent wire arm attached to a rock shaft f3 which is journalled in
bearings on the side of the spreader q² and has at its upper end a crank g³, the wrist
pin of which enters a slot in the lower end of a lever 3 which is pivotted to an ear i³
on the slide 2 carrying the spreader, Figures 17 and 18. The upper end of the
lever h³ has a pin ³ which enters a cam shaped slot 3, in an ear 13 affixed to the lever s².
The lever his oscillated by said slot and pin when the slide 2 is moved up and down
by the means above described, and is thus caused to impart a rocking motion to the
rock shaft whereby the cast off is oscillated.
The successive movements of the loop-spreader and cast-off are as follows: During
the latter part of the outward or backward movement of the needle, the loop spreader
is swung forward under the needle, as shown in Figure 23, and then is somewhat
depressed, as shown in Figuro 24 by the downward movement of the slide 2. At the
same time the needle is moved slightly forward to release the loop and then the cast
off is swung downwardly upon the released loop, and presses it downwardly from the
needle. The point of the spreader now stands directly over the tongue on the sole
and while it stands in this position the take up draws in the loop, which is caused by
the point of the spreader to tighten over the base of the tongue (Figure 24). The
spreader then swings back out of the way before the next forward movement of the
knife.
m³ represents a rest which supports the work below the point where the tongue
and loop forming devices act thereon. Said rest is preferably a roller journalled on
the swinging end of a lever n³, which is pivotted at 03 (Figure 1.) to the frame of the
machine and is normally pressed outwardly toward the operator by a spring p³,
attached at one end to said lever and at the other end to a fixed ear on the frame a.
The lever n³ has a segmental arm 3, containing a segmental slot s³, through which
passes a stud u³, affixed to the frame a. On said stud is a clamp or nut v³, which is
formed to bear against one side of the segmental arm 73, as best shown in Figure 16.
The stud u³ has a threaded portion u³, on which is a nut v³, engaging said threaded
portion. When the nut is turned in one direction on the stud u³ it is moved
laterally by its screw thread engagement therewith toward the segmental arm r³, and
is caused to press the clamp or washer against the segmental arm, thus pressing said
arm against a boss w³, on the frame a, the arm being thus gripped or clamped firmly
so that the rest m³ is made rigid. When the nut is turned in the opposite direction
it is moved away from and releases the segmental arm r³, so that the lever n³ and
rest m³ are free to move, the segmental arm then sliding freely on the stud u³.
The means whereby the nut v³ is turned to alternately hold and release the rest,
are an arm a, formed on said nut; a lever 64, pivotted at e to the frame a and
connected to the arm at by a link d¹, a cam e¹, on the disc m¹ and a spring f* which
holds the upper end of the lever 6' against the cam e. The oscillations of the lever b*
caused by the rotation of the cam et and by the spring f4 turn the nut v³ first in one
and then in the opposite direction, so that the rest is alternately made yielding and
non yielding, the yielding periods coinciding with the feed movements of the work so
that the rest is free to yield and conform to the variations in the contour of the surface
of the upper, while the non yielding periods take place while the tongue cutting and
loop forming devices are acting on the work, so that the work is firmly supported
when each tongue is being cut and the corresponding loop is being interlocked there-
with. The length of the swinging movement of the swing piece f, carrying the back

page_text: gauge depth gauge and feed dog, may be varied to vary the length of the feed
movement.
To effect this variation I provide the swing piece with an offset or ear 9¹ (Figures 2
and 7), which is perforated to receive and slide upon a stud or rod h, affixed to the
frame a, the frame having at this point a socket it, which contains a part of said stud,
and a spiral spring *, which bears against said ear 9* and presses the ear against a
wedge shaped collar or washer, k (Figure 7), mounted on said stud. Interposed
between said wedge shaped collar and a nut m², screwed onto the threaded outer end of
the stud is a vertically movable forked wedge n¹, which bestrides the stud and is
supported by a rod o*. The lower end of the rod ot may be supported by a treadle or
other device to be operated by the foot of the operator. It will be seen that the wedge
shaped washer and the end of the fixed socket constitute the stops that limit the
oscillating movements of the swing piece f, and that by raising or lowering the wedge n*,
said washer may be moved toward or from the socket, thus effecting any desired
variation in the length of the oscillating movements of the swing piece and in the
distance from tongue to tongue.
gauge d.
The shoe is presented by the operator, who presses the side of the upper near its
margin against the back gauge d, the rest m³ at this part of the operation being loose
or yielding and resting against the side of the upper at a point below the
The depth gauge t and feed dog c¹ then descends simultaneously until the depth gauge
bears on the sole close to its edge and the feed dog enters the sole slightly and clamps
it against the back gauge.
The back gauge, depth gauge and feed dog then move laterally and feed the work,
the rest m³ being at the same time locked and made to constitute an unyielding rolling
support for the side of the shoe. During the feeding movement the knife h¹ descends
obliquely, and at the close of said movement enters the sole cutting a tongue therein.
The knife then withdraws from the path of the needle and the latter descends, enters
the incision last made by the knife and passes through the between substance and the
upper. While the needle is in the sole, the back gauge moves away from the upper
and the depth gauge and feed dog move away from the sole, and said parts move
back to their starting position and at the same time the looper is moved to throw the
thread into the barb of the needle. The feed dog, back gauge and depth gauge next
move to bear on the work, the back gauge and feed dog clamping the work as before.
The needle then withdraws from the work, drawing a loop of thread through the
upper and the between substance, at the same time the take up exerts a tension on the
thread during the first part of the operation of drawing the loop, and then releases
the thread and permits it to run loosely during the remaining part of the operation.
After the loop is drawn out, the spreader 92, moves forward into the loop and
spreads it. The needle then moves slightly forward to release the loop and the cast.
off then swings over and removes the loop from the barb of the needle. The take up
lever then moves and takes up the loop, drawing it tightly across the tongue on the
sole. The feed dog, depth gauge and back gauge then move and feed the work, and
the operation already described is repeated, and so on.

In the figures last referred to.
a represents the supporting frame; b represents the driving shaft to which are
affixed the operating cams; c represents the curved needle. The oscillatory needle
arm d, which carries the needle is mounted on a fixed stud or bearing e, affixed to the
frame a, and is oscillated on said stud by a slide f, adapted to move vertically in a
guide in the frame a by a cam groove g, in a disc h, affixed to the driving shaft b,
said groove receiving a stud or roller on the slide f, and a jointed connecting rod i,
pivotted to the lower end of the slide f and to the needle arm d, and communicating
the movements of the slide to the needle arm.
j represents a V-shaped knife or cutter which is formed on or attached to a shank k.
Said shank is attached by screws 1, 1, (Figure 11'), to a hub, m, which is journalled on
the stud e on which the needle arm d is also journalled, and is capable both of
oscillating and of moving laterally on said stud, so that the knife can be first
moved laterally into the path through which the needle moves (but while the needle
is elevated or drawn back), then moved forward in the arc of a circle and in the same
path in which the needle afterwards moves in entering the work, thus striking and
cutting a tongue n, in the side of the sole of the shoe being acted on by the machine,
then withdrawn from the sole by the backward movement in the arc of a circle, and

finally moved laterally away from the path in which the needle moves.
place while the needle is elevated or drawn back from the work so that when the
needle decends it will follow the knife and enter the incision formed by the knife in
cutting the tongue in the sole, and in returning will draw a loop of thread through the
sole and under said tongue, said loop being afterwards cast off and interlocked with
the tongue.
The described movements are imparted to the hub m and knifej by the following
devices, viz: first, a lever o having a slot p engaged with a stud q on the hub m, and
pivotted at (Figure 1) to a studs, which is journalled in a bracket t on the frame a,
the lever o being adapted to oscillate on the pivot r in a plane parallel with the path
in which the needle moves, and with the stud s in a plane at right angles with said
path; secondly, a cam a¹, on the periphery of the disc h; thirdly, a spring b¹, which
holds one arm of the forked upper end of said lever in contact with said disc, the
cam a¹ and spring 6 conjointly giving the hub e and knife; the described lateral
movements, fourthly, a cam c (Figure 1¹), on the rear edge of the disc h; and
fifthly, a spring d², which presses the other arm of the forked
against the rear edge of the disc h, the cam c¹ and spring der end of the lever o
co-operating to give
the hub e and knife j the described oscillating movements. It is obvious that the
movements of the lever may be produced by positive means, as by cam grooves
engaging studs on the forked end of said lever.
el
represents a rest or gauge against which the shoe is held during the stitching
operation, and f represents a pointed feed dog or short awl which co-operates with
the gauge or rest in feeding the work. The rest and dog are attached respectively to
arms g, h, which are mounted to oscillate independently on a stud or centre i common
to both. Said stud is attached to an ear forming a part of a plate or swing piece j',
which is pivotted at k¹, to the frame of the machine and is oscillated in a plane parallel

page_text: with the direction of the feed movemer' of the work by a cam 1, on the driving
shaft b (said cam being within an aperte in the swing piece, as shown in Figure 4¹)
and a spring m³, (Figure 6¹) interped between the frame a and an ear on the
swing piece j, said spring pressing the swing piece outwardly against an adjustable
nut n', on a pin o³, affixed to the frame a and passing through the spring m¹ and an
orifice in the swing piece. The nut n therefore serves as an adjustable stop to limit
the movement of the swing piece by the spring m¹.
The rest and dog f¹ are oscillated in opposite directions on the stud and are
thus caused to alternately approach and recede from each other to grasp and release
the work, by a slide p¹ (Figures 4 and 5¹) adapted to move vertically in a guide in
the swing piece, two links q¹, r², connecting the lower end of said slide respectively
to the upper ends of the arms g' h¹ supporting the rest and dog, and a cam groove s¹
in a disc t¹ on the driving shaft ; said groove receiving a stud on the slide p¹. The
slide p is reciprocated vertically by the rotation of the disc t¹ and through the
links oscillates the arms h¹, g, and thus causes the rest e¹ and dog f¹ to approach
and recede from each other.
Between the dog f¹ and rest e¹ is a rest a² (Figure 3¹), which supports the work
against the upward pressure and thus keeps it down at the proper point. To the
rest a² is attached a plate or flange 62, which keeps the edge of the upper from being.
turned over onto the sole.
²represents the looper which consists of an arm pivotted to a bracket d² in the
frame a, the swinging end of said arm having an orifice through which the thread
passes. To the pivotted or inner end of the arm c² is rigidly attached a lever e²,
having a slot which receives a pin f2, on the swing piece ¹. The oscillations of said
swing piece cause the pin to oscillate the arm e, and the looper thereto attached,
and thus cause said looper to swing the thread against the needle when the latter is
advanced as hereinafter described.
The cast off is composed of an arm g², having a longitudinal curvature approximating
that of the needle and slotted longitudinally so that it can pass over the needle as
hereinafter described, and provided with two fingers or jaws h², h², which are pressed
through holes in its sides into its needle receiving slot by springs 2, 2 attached to the
outer sides of the cast off, said jaws passing through holes in the sides of the cast
off and co-operating to grasp the thread on the needle when the latter is within the
cast off. The devices which operate the cast off are as follows viz: a slide or plate j²
to which the cast off is attached, a cam k² on a disc 12 on the driving shaft b, a
spring m², which presses the upper end of said slide upwardly against the disc 12,
a lever n² pivotted at o² to an ear on the frame a (the slide 2 being supported by said
lever and adapted to slide thereon by means of slots p², p² in the slide and screws q², q²
on the lever) a cam ² on the rear edge of the disc 12 and a spring s², which presses the
upper end of the lever n² against the rear edge of the disc 12. The lever n² is
oscillated by the cam² and spring s² in a plane parallel with that in which the needle
moves, and the slide with the cast off thereon oscillates with the lever n² besides
being independently moved by the action of the cam k² and spring m².
The take up is composed of a lever t2 pivotted at a³, to the frame a and having at
its lower end a roller 63, around which the thread passes to and through the looper c².
The upper end of the lever 2 is pressed by a spring c³, against a cam d³ on the edge
of the disc t' on the driving shaft. The thread passes from the supplying spool or
ball over the roller 63, and from thence, over a roller e³, journalled on a fixed bearing,
and from the roller e³ to the looper c². The oscillations of the lever t² caused by the
cam d³ and spring c³ move the roller 63 toward and from the roller e³. The movement
of the roller 63 away from the roller ³ causes a backward pull on the thread, and thus
takes up the loops after they are disengaged from the needle by the cast off as
hereinafter described.
f³ represents a rest or support which is arranged to bear against the upper at a
point below the sole and is operative or rigid only when the needle is entering the
work, the said rest being unsupported, and allowed to yield when the work is being

page_text: a,
fed. The rest f³ is composed of an arm or lever pivotted at gå to the frame
its
lower or swinging end projecting outwardly to a point below the path in which the
needle moves. The lever is intermittingly supported in position to cause its
swinging end to act as a rest for the work by a cam ½³, which is pivotted at 3 to the
frame of the machine, and is alternately raised and lowered by lever j³, pivotted at k³
to the frame a, and connected by a rod 13 to the cam h³, a cam m³ on the rear side
of the disc t¹ and a spring n³ which forces the upper end of the lever j³ against
the cam.
The cam is raised by the described devices, as shown in dotted lines in Figure 1',
and thus caused to hold the lever or rest while the needle is moving forward and the
cam is depressed and caused to release the lever or rest f³ while the work is being
fed. The spring n³ enables the cam to be arrested at any desired point in its upward
movement by the contact of the work with the lever or rest f³ so that the rest conforms
to the shape of the shoe and projects more or less when supported by the cam according
to the part of the shoe that is presented to it. The cam is serrated or roughened so
that it will not slip or yield under the pressure exerted on the rest by the shoe. The
operation of the modified mechanism last described is substantially the same as that
of the mechanism first described.
In Figures 24, 25¹ and 26¹ we have shewn means whereby the knife is moved to
and from the sole by a movement produced by swinging the shank supporting the
knife on a vertical axis, and at the same time giving said shank a vertical movement
on the said axis, the vertical movement being downward when the knife is moving
toward the sole, and upward when the knife is withdrawing. The knife is thus given
a winding or spiral motion from its point of rest outside of the path in which the
needle moves, into said path at the point where the needle enters the sole.
In this modification the shank k of the knife is attached eccentrically to the lower
end of a cylindrical sleeve p³, which is journalled on a vertical stud or pin g³ affixed to
a slide which is reciprocated vertically by means of a bell-crank lever pivotted to
the frame and a cam groove w³ in a disc on the driving shaft, said groove receiving a
stud or roller on the lever v³.
In the sleeve p³ is a spiral slot s³, which receives a stud t3 affixed to the frame a.
The oscillations of the lever v causes the slide 3 and the knife supporting sleeve p³
journalled therein to reciprocate vertically and at the same time the engagement of
the spiral slot in said sleeve with the fixed stud 3 gives the sleeve a rotary motion
while it is moving vertically the result being a winding or spiral movement of the
knife, which is excentrically attached to the sleeve p³.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is
