PROVISIONAL SPECIFICATION.
Improvements in Lasting Machines.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, London,
in the County of Middlesex, Patent Agent, do hereby declare the nature of this
invention (a communication to me from abroad by Henry Wellington Dean, of
Norristown, County of Montgomery, and State of Pennsylvania, United States of
America, Inventor) to be as follows:-
My invention is directed to improvements in machines for lasting shoes; and the
objects of my present improvements are to produce a better organization of the
working parts of the machines to facilitate the operation and give better and more
satisfactory results in the work.
My improvements are directed to provisions whereby the heel and toe clamps are
operated, adjusted and locked upon the last by a hand-lever to suit the different
sizes of lasts, and in which such adjustment is quickly and accurately determined
and the operation effected.
My improvements are also directed to provisions whereby in the several distinct
steps of the operation of lasting the upper to the inner sole, there are no two move-
ments that are necessarily completed together, but their operation is made continuous
under the control of an automatic stop device and the operator.
I have produced a novel construction of clamp for the heel and for the toe, a
novel construction of toe-wiper and toe-rest, and a novel construction of side rubbers
or wipers, whereby in their separate and distinct functions the upper is strained and
moulded perfectly and smonthly over the last. I have produced a novel construction
of heel and toe crimping devices, whereby they are caused to operate effectively in
laying the edges of the upper over and upon the inner sole. I have produced a
novel construction of devices for carrying and adjusting the side-lasting fingers,
whereby they are firmly supported and readily adjusted.
I have made improvements in the organization of the complete machine, in its
construction, and in its various devices and combinations, whereby the functions,
separate and distinct and co-operative, are rendered effective for satisfactory work.
A suitable frame is constructed of such form and size as will support the working
parts of the organized machine, the cam-shaft whereof is mounted in bearing-boxes
at each end of the frame. Upon this shaft are splined two cams, of like construction,
but formed as rights and letts, adapted to slide freely upon said shaft, to rotate with
it, and to operate, respectively, the toe and heel clamping and crimping mechanism,
as will be hereafter described. At the top of the frame and upon horizontal guide-
ways, are mounted two carriages of like construction and adapted to slide upon said
guideways coincidently with the sliding movement of the cams upon their shaft. The
carriage at the left carries the toe clamping and crimping mechanism, and the
carriage at the right carries the heel clamping and crimping mechanism. A top
plate and two depending side plates compose each carriage, the top plates being
fitted to slide in the guideways and forming the support for the carriage in the
frame, while the depending side plates support the carriage laterally between interior
projections of the side walls of the frame.
Projecting horizontally from the lower inner end of the depending side plates of
the carriage at the right, is a bracket that has pivotally supported thereon the
adjustable last-supporting jack, upon which the last is primarily supported. Pivotally
mounted in the upper end of the jack is a stud that fits in a hole in the last and is
made adjustable by the nut.
The last having been placed upon the jack, it is clamped between a toe-clamp,

page_text: supported upon a vertical bracket, rising from the top plate of the carriage, and a
heel-clamp supported upon a bracket, rising from the top plate of the other carriage,
and the clamping is effected by the movement of the carriages toward the last.
The means for effecting these movements of the carriages I will now describe.
Rigidly connected to the under side of the top supporting-plate of the carriage is a
horizontal rack-bar, placed at the outer side of the depending side plate, and pivoted
to one of the depending side plates of the other carriage is a rack-bar, that extends
over to the carriage and directly under the rack-bar the teeth of the said racks
extending toward each other. A pinion is secured upon the inner end of a horizontal
stud, rotatively mounted in bearings in the side wall of the machine, between the
rack-bars and this pinion is operated by a hand-lever so as to give a uniform
reciprocating movement in opposite directions to the rack-bars and through thou to
the carriages to carry the toe and the beel c'amps toward the last, and thus clamp
the same and carry them away from the last after the shoe has been lasted.
The free end of the rack-bar is supported upon a roll mounted on the inner wall
of the frame so as to maintain it in gear with the said lever-pinion. This pinion-
stud has at its outer end a conical hub which terminates in a screw-threaded stem at
the outer side of the frame, the taper of said hub standing outward and upon which
is mounted a hand-lever. This hand-lever is composed of two parts, and one part
has a conical bearing that fits the before-mentioned conical hub and is frictionally
clamped thereon by a nut upon the screw-stem thus tightly locking the pinion and
the hand-lever together.
This way of connecting the hand-lever with the pinion
admits of the proper adjustment of the carriages with relation to each other and to
the last, and also with relation to a gauge fixed on the frame, by which the heel and
toe clamps are locked when clamped upon the last.
One part of the band-lever is pivotally connected to the other part by means of a
screw, and it will be understood that the one part extends beyond the pivotal con-
nection and is engaged by adjusting-screws in lugs upon the other part so as to abut
against the opposite sides of the extended end of the one lever, and thus allow of a
finer adjustment of the hand-lever with relation to the gauge and its adjustable stop
than could be effected by the frictional conical bearing previously described. This
gauge is composed of a segmental strip of metal placed upon the frame in the path of
the hand-lever, and is provided with a series of holes that are engaged by a spring-
latch upon the outer end of the hand-lever, and so hold it in a desired position.
These holes in the gauge are so spaced with relation to each other that the movement
of the lever from one hole to another would move the toe and heel clamps just far
enough to clamp the next half-size last-that is, the holes are graduated to half sizes
of lasts.
To enable the operator to carry the clamping-lever to the proper hole in the gauge
to clamp the size of last he may be using, I have provided an adjustable stop-block.
Referring now to the heel-clamp, it is composed of two metal side plates hinged
to a rear plate bent to conform to the heel of the last. Fastened upon the inner
sides of the side plates and extending around the inner surface of the rear plate, but
at some distance therefrom, is a rubber cushion against which the heel of the last is
clamped. At the rear side of this rubber cushion is fastened a metal plate having
pivoted thereto two arms which extend through a slot in the rear plate, and which
are pivoted to arms rigidly fastened to the plates. When therefore, the clamp is
pressed against the heel of the last, the cushion will be forced back toward the rear
plate, and by means of the pivoted arms and the rigid arms, the side plates will be
forced in toward the last and thereby conform the counter and heel to the shape of
the last.
As a provision for allowing the clamp to adjust itself to the heel of the last, it is
pivotally mounted on a bracket.
The toe-clamp previously described as being pivotally mounted upon the bracket,
is composed of a metal bar, bent over at its upper end and formed into a semicircular
widened part to engage with the toe of the last. At its lower end it is provided

page_text: with an adjusting-screw, by which pressure on the toe of the last is produced and
regulated, and at or near the middle of its length it is provided with two arms,
which embrace the said bracket and by which said bar is pivoted thereto.
At the inner ends of the depending side plates of the carriage, and between them, is
fitted a vertical slide in grooves in said plates, which has a horizontally-projecting
bracket. The opposite side of said slide at its lower end is provided with a roll that
engages with a cam and by which it is raised. It falls by its gravity. Mounted on
the bracket is a short screw-stud, and telescoping with said stud is a tube, which
passes through a guide-arm, extending from the upper end of the slide, and in the
upper end of this tube is fitted the supporting screw-stem of the toe-rest. The tube
contains a spring, by which it has a yielding support upon the screw-stad. This tube
is provided with a vertical slot at its lower end to receive a pin on the screw-stud,
whereby the tube is held in proper relation to the screw-stud against the force of the
spring tending to separate them. This relation is maintained by a screw-sleeve on
the lower end of the tube, and the pin abutting against said sleeve, so as to allow this
tube to yield under the action of the toe-rest when the slide is raised. The limit of
the yielding movement of the tube is determined by lock-nuts on the screw-stud, and the
tension of the spring is adjusted by the afore-named sleeve. The toe-rest is pivotally
connected with its supporting screw-stem, so as to allow it to properly adjust itself
to the last, and the said screw-stem is provided with lock-nuts, by which to support
the said screw-stem within the end of the tube and adjust it to the proper beight
thereon.
The toe-rest is preferably made of rubber, of V shape, open at both ends. Its
inner sides terminate in a longitudinal bottom groove, and are slightly convex length-
wise and terminate in a downwardly-inclined concave flaring inner end, so that it
will conform to the toe and instep of the last and strain and mould the upper thereon
as it is raised against the toe-crimping mechanism, against which the last is firmly
held by the pressure of the spring in the tube. At the inner side of the toe-clamping
bar is pivotally hung, by means of a lug, a tripping-bar, against the foot of which the
adjusting-screw abuts. At its lower end this tripping-bar is formed with a too-shaped
projection that abuts against the inner side of a slide, fitted in vertical guides in the
inner wall of the bracket. This slide has an enlarged foot part, which is connected
by a screw-post to the arm of the slide, said post entering a screw-tap in the slide-
foot, and has a nut by which to adjust the slide in proper relation to the tripping-bar.
Now by turning the screw the clamping end of the toe-clamp will be caused to move
toward or away from the last, as may be desired to set the toe-clamp to act with more
or less force against the last. In the operation of this clamping and tripping device
the can causes the slides to rise which will free the latter from the toe of the tripping-.
bar and allow the lower end of the said tripping-bar to swing under the said slide and
thereby release the toe-clamp. This releasing of the toe-clamp allows the toe-wiper
which is carried by the slide to rise free of the toe-clamp and to draw the upper tight
around the toe of the last, as I will now describe. This toe-wiper is composed of a
thin plate of spring metal, bent to conform to the shape of the last at the toe, but it is
a little smaller than the toe, so that when it is pressed up around the last it will bear
sufficiently tight against the upper to draw it firmly around the last. The edges of
the toe-wiper are made slightly rounded or flaring, so as not to scratch or cut the
upper. Riveted on the back of the wiper-plate is a strip of metal that fits in a slot in
the foot of the slide and is held in place by a spring, secured upon the slide, so that
its upper end extends over the said slide and projects through a slot in the back
of the wiper and is slightly hook-hent to take hold of the wiper and retain it in
place, while at the same time permitting of its ready removal when a larger or smaller
wiper is desired.
Referring to the co-operation of the toe-clamp and of the toe-rest, at the time the
latter is raised the toe-clamp is released from its lock and is caused to fall back by
gravity due to the manner in which it is hung by its pivot-arms, and in thus falling
back at the top it swings forward at its lower end, carrying with it the lower end of

page_text: its hanging trip-har. The relation of the toe rest support to the toe-clamp is such that
the latter is held in position by the co-operation of the toe-rest support and the
hanging trip-bar when the toe-rest support is down, and the toe-clamp is released
when the toe-rest rises.
Referring now to the toe and heel crimping devices, they are of similar construction
and are carried upon the under sides of the top piates, which are mounted upon the
supporting-plates of the carriages. These top-plates are supported for adjustment in
relation to the last, as I will now state. The front ends of these top plates are
mounted on posts that are provided with adjusting-nuts so as to raise and lower said plates
to the proper level relatively to the last. The connection of these posts with the top
plate is by a ball-joint so as to allow said plates to be tilted from the rear end so as to
bring the crimping fingers carried by said plates, in proper line with the spring of the
last. This tilting of the top plates is efferted by means of a screw-threaded bar
pivotally connected to the outer end of each of the top plates and provided with a
hand screw having a bearing upon the supporting-plate of the carriage.
Fitted to slide in a groove on the under side of the top plates is a bar having at its
inner end a projecting lug or nose, under and against which the last is pressed by the
toe-rest. This bar has pivoted at its inner end, the crimping fingers which approximate
in form to a crescent. These crescent fingers are provided with arms or lugs, which
are pivoted to links which are at their other ends pivoted together and upon a plate
which is fitted to slide in guideways on the under side of the top plate so that the
movement of said plate will cause the fingers to have a sweeping or circular motion
over the toe of the last and thereby crimp and lay the leather."
Projecting downward from the under side of the plate of each of the before-
mentioned carriages, is a lug to which is pivoted one end of an adjustable link, the
other end of which is pivoted to the upper end of a rocking lever, which is mounted
in vertical position between the depenfing side plates of the carriages on a cross-stud.
The lower ends of these levers are forked and connected to a small cross-bar fitted to
slide in guideways on the inner walls of the depending side plates of the carriage and
a roller, mounted on a short stud on the under side of said cross-bar, is adapted to
work in the cam-groove of the right and left camus, so that these levers operate the
said plates of both carriages simultaneously.
The adjustments made by the screw-links are to adapt the heel and toe crimping
fingers to suit lasts having different widths of heels and toes by increasing or
diminishing the extent of the movements of said fingers.
Projecting downward from the outer end of the bar is a lug to which is pivoted the
upper end of a link, the other end of which is pivoted to the upper end of a rocking
lever, which, like the other lever, is mounted on a cross-stud, between the depending
side plates of the carriages. The lower ends of these levers are forked and connected
to a small cross-bar, fitted to slide in guideways on the inner walls of the depending
side plates of the carriage, and a roll, mounted on a short stud on the under side of
said cross-bar, is adapted to work in the cam-groove of the right and left cams, so
that these levers operate the said bars of both carriages simultaneously.
As the structure and operation of the heel and toe crimping mechanisms are
identical, it is only necessary to describe the crimping devices of one of these
mechanisins in their relation to the last.
As the closing action of the crimping-fingers over the toe upon the edges of the
upper is liable to cause puckers and interfere with the smooth laying of the edges, I
have provided auxiliary side-lasting fingers which i will now describe. The said
fingers are formed of flat pieces of spring metal, carried upon the upper ends of
levers, which are pivotally connected to the inner ends of the depending side plates
of the carriage, and extend down to and connect by rolls with face cam-grooves of
like form, and both formed one within the other to cause the said fingers to move
over the last just before the crimping-fingers close, and to move away from the last
after the crimping fingers have closed. In this preliminary laying movement the side
fingers are so formed as to allow the crimping-fingers to pass under them. About the

page_text: same time the closing movements of the crimping-fingers occur, the side rubbers or
wipers operate to bring up the upper and draw and strain it over and about the
bottom of the last, as I will now describe.
The said wipers or rubbers may be formed of separate and distinct parts used in
pairs for each side of the last. They are preferably each formed of a single piece of
leather, the part operating upon the hollow or shank sides of the last being wider and
longer than the part operating upon the swell of the last; but both are carried by a
lever-frame, and the lever-frame of each set is supported and operated simultaneously.
These lever-frames I will now describe preparatory to describing the particular
means for mounting the rubbers to permit of their yielding and rubbing action.
Each lever-frame consists of arms, connected in pairs about the middle of their
length by a cross-bar. One of these lever-arms is made longer than the other and
extends down, and is pivotally connected at its lower end to a cross-head, fitted to
slide vertically in guideways fixed to and depending from the sides of the frame of
the machine. A bolt is mounted in these lever-arms, above their connecting cross-
bar, and upon this bolt is pivotally mounted the support for the large wiper, and
which is preferably made of a U-shaped bar, with its ends loosely mounted upon
each end of the said bolt. In the upper end of this wiper-support is socketed a screw-
stud, provided with an adjusting-nut which rests upon the top of this wiper-bar, and
rising from this screw-stud, and preferably integral with it, is a plate curving over
toward the last with a convex edge conforming to the hollow of the last, and having a
width suited to the hollow side of the last. Upon and over the upper curved edge of
this plate the leather rubber is riveted, and extends down in a substantially vertical
position and slightly tapering from the top, and is secured in a clamp pivotally
mounted in the wiper-bars and stretched by a coil-spring, which connects the lower
end of the rubber to the cross-bolt of the lever-frame and renders the rubber flexible
at every point. The clamp for the lower end of the rubber is composed of two plates
and between which the small end of the rubber is firmly clamped over and upon the
edge of the inner plate by screws, passing through each end of the outer plate into
the edge of the inner plate. This inner plate is secured edgewise in the slotted end
of a screw-rod the other end of which is held in a cross-bar loosely mounted in
bearings in the sides of the U-shaped wiper-bar, the said screw-rod being supported
on said cross-bar by a nut by which the screw-rod can be set out or in.
By this
means of mounting the wiper it can be adjusted vertically by the screw and nut; it
can be adjusted out or in at its lower end by its supporting screw-rod; it can yield
along its length by reason of the freedom of its supporting screw-rod to rock with its
supporting cross-bar in its bearings in the sides of the U-shaped bar, and it is
constantly strained over the said rocking support by the pulling action of the spring.
It is perfectly adapted for different forms and for right and left lasts.
Supplementing the function of the rubber to yield as stated, it is firmly but
yieldingly pressed forward and held against the last by a spring extending from the
upper end of one of the arms of the lever-frame to the upper end of the U-shaped
bar, and supported by a rod and nut which adjustably connects the rubber-support
with the lever-frame. This allows the rubber-support to yield in the arc of a circle
upon its bearing-rod, while the rubber itself has an independent yielding function, as
stated, whereby it is adapted to act with a moulding pressure to hold and strain the
upper as it is raised in contact with the hollow or shank side of the last.
It may be
readily replaced when worn out by a new one. Co-acting with this flexibly-acting
rubber for the shank, I provide a small rubber having a flat and preferably non-
yielding surface adapted to operate upon the toe or the swell part of the last. It is
formed of a piece of leather riveted to a flat plate provided with a round stem,
secured in a socket formed in the upper end of an arm, mounted loosely upon the
rod, and which is constantly pressed forward at its upper end by a spring, connecting
its upper end to the upper end of one of the arms of the lever-frame, the said spring
being supported by a rod and nut, which adjustably connect the arm with the lever-
frame. A spring-pin fastens the shank of this small rubber in its socket, so as to

page_text: permit of its easy removal and replacement. This toe-operating wiper part is
mounted so as to set back from the face of the shank operating wiper part to suit the
swell of the last, but they both move so as to act together. In the starting of these
wipers they are brought against the sides of the upper, below the top of the last, and
are carried up a little so as not to interfere with the action of the side-laying fingers,
now described.
Each arm of the lever-frame is formed with a cam, inclining upward and inward
on the outer edges of and about the middle of the length of the arms, so as to
act against rolls, which are mounted upon short shafts supported in bearings in the
ends of brackets, which extend inward from the inner walls of the opposite sides
of the frame. At a point centrally and near the top of the cross-head, is mounted
on its side a roll, which works in a cam-groove, and which is fixed upon and rotated
by the cam-shaft. When the wipers are in their normal open positions, the rotation
of the said cam will cause the cross-head to rise, and simultaneously the cams of the
lever-arms will be caused to ride upon the rolls and thus force the wipers inward
upon the sides of the upper, for the purpose stated. The wiper-arms stand inclined
inward from their pivotal connections, so as to overhang their lever carrying-frame
and hold the acting wiper-surfaces in vertical positions in relation to the last, and
particularly is this important in maintaining the strap-wiper in position to have its
upper end act upon the shoe-upper as it is moved inward and upward upon the shoe-
upper, so as to stretch and lay the latter well over the edges of the inner sole, and
there hold it for the action of the crimping-fingers. This rubbing and smoothing
action upon the side of the shoe-upper, and upon its upper edges over the edges of the
inner sole could not be obtained if the straps were pulled away from the last at their
upper ends.
The side-lasting fingers for laying the edges of the upper are arranged upon
carriages at each side of the machine, so as to stand crosswise above the top of the
frame, on a level with the bottom of the last, and are moved toward and from the
same. These fingers are formed of long narrow pieces of spring metal, arranged in
parallel relation separated a distance about equal to their width and of sufficient
number to fill the space over the last between the crimping-fingers when the latter
are in their closed positions. They are supported at two points upon their carriages,
which latter are formed of a horizontal plate and vertical end plates and fitted to
slide in ways on the top of the frame of the machine, which at this point is made
wider than the end portions of the frame, so as to accommodate the length of the
fingers and the movements of the carriages. These fingers are supported independent
of each other at their outer ends and at the outer side of the carriage by means of
L-shaped metal holders, the vertical part. whereof has a hole within which is snugly
fitted the round end of the shank of the finger, where it is fastened by a key, pinned
in said holder so as to allow the finger to be turned. In the horizontal part of this
angle-holder is fastened a screw, which passes down through a screw-threaded hole
in the top of the carriage, and depending from said angle-holder is a guide-stud, which
passes down through a hole in the top of the carriage. This construction allows the
vertical adjustment of the outer end of the finger and keeps the angle-piece in proper
relation to the finger. At the inner side of the carriage the fingers are also supported
independent of each other by means of sockets or boxes, each one placed between
two screws and having square openings within which the square shanks of the fingers
are fitted. These socket-boxes are formed at each side with approximately spherical
cavities, whereby they are seated and adjustably supported upon correspondingly-
formed shoulders formed upon shanks of screws which pass down through screw-
threaded holes in the top of the carriage. By this construction the acting ends of the
fingers are adjusted vertically, while the socket boxes by this adjustment permit the
fingers to be automatically turned. The semi-spherical cavities extend about half
the thickness and open at the bottom of the box and merge into semicircular cavities
in the upper half of the box, which exactly fit the necks of the screws above their
conical shoulders, while the neck of the screw terminates in a circular collar, which

page_text: exactly fits into a semi-circular recess in the top of the box around the side recess
whereby the box is permitted to move over the screw-collar in adjusting the box on
an incline. These top recesses for this purpose are made with inclined bottoms,
and in thus allowing the turning of the boxes the said collars also serve to give
a firm support to the boxes against the upward pressure upon the fingers in
moving over the last. The object of this construction is not only to adapt the
fingers to different sizes of lasts, but to lasts in which the spring of the bottom
varies. The fingers are firmly supported upon the screws, by which they can be
independently adjusted vertically to positions higher or lower to conform to the
line of the spring of the last, while each finger is by such adjustment rocked so
as to tip it out of a true horizontal line from edge to edge, and thereby bring
each of said fingers to a set to accommodate its under flat side to the spring of
the last, and thus effect the straining and uniform laying of the edges of the
upper upon and over the inner sole between the crimping-fingers. In this operation
these fingers are moved toward and from the last in a manner which I will now
describo.
The top plates of the carriages of the side-lasting fingers are formed on their under
sides with downwardly-projecting lugs between which works the upper rounded end
of a rocking lever for each carriage. These levers are mounted upon the short shafts
of the brackets and between the lever-arms of the side rubbers or wipers and extend
below said brackets and are provided at their lower ends with a roll, which works
in a slot in a cross-head, which is fitted to slide vertically in guideways fixed to
and depending from the sides of the frame of the machine by the side of the
guideways. The slots stand in the cross-head obliquely outward, so that when the
cross-head is raised its connected levers will be operated to carry the finger-carriages
outward to their normal positions. At a point centrally and near the top of the
cross-head is mounted on its side a roll, which works in a cam-groove which is fixed
upon and rotated by the cam-shaft. The descending movement of this cross-head will
cause the carriages to move inward and carry the fingers into action to lay the edges
of the upper, as stated, and to maintain them in such positions during the operation
of tacking the upper to the inner sole. In this position of the lasting devices the
machine is locked out of action during the tacking of the upper all around its edges
to the sole between the finger crimping and laying devices by means controlled by
the treadle, which I will now describe in connection with the driving-shaft.
Mounted in bearings at the rear side of the machine is the driving shaft, having
mounted upon one end, preferably to the right, a loose band-wheel, whereby the
power is applied to the machine. Upon this shaft is a pinion, which gears with a
wheel fixed on the end of the cam-shaft at the outer side of the end of the frame.
Between the pinion and the band-wheel is a clutch, the sliding part of which is
connected to and slides with the band-wheel, and is also connected with a clutch-arın
mounted in a bracket on the side of the frame and having a horizontal branch, making
a bell-crank lever, which, by means of a link is coupled with a treadle, connected to
a tie-rod at the rear side of the frame. On the inner face of the cam-sba't gear-
wheel, is fixed an annular rim having circumferential notches or shoulders suitably
disposed to control the several stops of the machine. A slide is arranged vertically
in suitable confining-guideways at the inner side of the end frame, and is provided
with a horizontally-projecting stop-dog, adapted to ride upon the circumference of
the annular rim of the gear, and to be forced into the notches of said rim as the
latter revolves. For this purpose the dog-slide is connected at its lower end to the
treadle by means of a screw-link screwed into a swivelling stud suitably mounted in
the horizontal arm of the clutch-lever, which is constantly pulled up by means of a
spring connected to the end of said arm and to the frame. The object of this
adjustment is to time the disengagement of the clutch with the engagement of the
stop-dog, and vice versa, and it is effected by adjusting the screw-link, so that the
clutch and the dog will always take their proper hold. To relieve the shock caused
by the action of the dog in stopping the machine, a brake is brought into action at

page_text: the same time the dog acts. This brake consists of a brake-wheel on the fixed clutch
part of the power-transmitting shaft and a brake-arm fixed upon the stud of the
clutch-lever, the relation of the brake parts being such that when the stop-dog enters
a notch in the gear-wheel rim the brake-arm will be constantly pressed up against
the brake wheel, and thus relieve the shock and hold the machine out of gear.
The machine being at rest and all the lasting parts open, the last, with the upper
and the inner sole thereon, is placed upon the heel-pin of the jack, and the operator
raising the hand-lever, operates the heel and toe carriages to bring the heel-clamp and
the toe-rest in contact with the last to firmly clamp it in position during the operation.
In this clamped position the parts are locked by the spring-pin of the band-lever
entering the proper hole in the gauge, which is determined by the gauge-stop limiting
the movement of the hand-lever. During this operation the machine is locked out
of power by the stop-dog. The operator then depresses the treadle, which withdraws
the stop-dog, engages the clutch, and the machine starts. The cams then act by the
cam parts to move the heel and toe crimping devices forward in the relation to the
last. At this moment the auxiliary side fingers are caused to close over the toe by
the cams, and immediately following this movement of the auxiliary side fingers the
toe-wiper is caused to rise and strain the upper, so as to mould it around the toe of
the last by the edge-cam. Simultaneously with the action of the toe-wiper the
toe-rest is also caused to rise, and by its compressing action upon the upper across
the instep and ball of the top of the last draws the upper tightly to conform to the
top of the last. As soon as the toc-rest comes in contact with the last, it is depressed
by the latter for about an inch against the tension of its supporting-spring, until
the sleeve strikes the nut, when the toe-rest will be carried up by the cam so that
its sides will spread over the upper and strain it over the last. In this action the
groove allows the sides to open slightly as they ride up over the last, while the toe-rest
tilts upon its pivot, to allow its concave flaring end to conform to the instep of the
last. During this operation the side rubbing or wiping devices are caused to rise
and strain and carry the upper up toward the bottom of the last so as to draw the
upper perfectly tight around the last by the action of the cam. During this operation
the side-lasting fingers are caused to move forward and over the bottom of the last,
carrying the edges of the upper over the bottom of the last by the action of the
cams and cross-head. During this operation the heel and toe-crimping devices are
caused to close by a sweeping circular movement, carrying the upper over the inner
sole at the heel and at the toe of the last by the action of part of the cams.
It will be understood that in the several and distinct steps of the lasting operation
above stated there are no two movements that are necessarily completed together;
but their operation is made continuous by the successive following of the cams during
the operation of the machine, as regulated by the space between the stop-notches.
At this point the automatic stop device is brought into action by the stop-dog sliding
into the stop-notch in the annular gear-rim, which stops and locks the machine out
of action. The upper is now ready to be fastened to the inner sole, which may be
done by tacks, as stated, or in any desired manner. After the upper is fastened, the
operator then placing his foot upon the treadle starts the machine, the operation of
which brings the stop-notch into position to be locked by the stop-dog, but during
which operation the crimping-fingers are opened which gives the operator a chance
to see if the edge of the upper is fully fastened at the heel and toe, after which the
treadle is again depressed, which again starts the machine, which brings the next
stop-notch into position to be locked by the stop-dog, which brings the machine to
its normal condition.

COMPLETE SPECIFICATION.
Improvements in Lasting Machines.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, London,
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a
communication to me from abroad, by Henry Wellington Dean, of Norristown,
County of Montgomery, and State of Pennsylvania, United States of America,
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention is directed to improvements in machines for lasting shoes, and
the objects of my present improvements are to produce a better organization of the
working parts of the machines to facilitate the operation, and give better and more
satisfactory results in the work.
My improvements are directed to provisions whereby the heel and toe clamps are
operated, adjusted and locked upon the last by a hand-lever to suit the different sizes
of lasts, and in which such adjustment is quickly and accurately determined and the
operation quickly effected.
My improvements are also directed to provisions whereby, in the several distinc
steps of the operation of lasting the upper o the inner sole, there are no two movements
that are necessarily completed together, but their operation is made continuous under
the control of an automatic stop device and the operator.
I have produced a novel construction of clamp for the heel and for the toe, a novel
construction of toe-wiper and toe-rest, and a novel construction of side rubbers or
wipers whereby in their separate and distinct functions the upper is strained and
moulded perfectly and smoothly over the last. I have produced a novel construction
of heel and toe crimping devices, whereby they are caused to operate effectively
in laying the edges of the upper over and upon the inner sole. I have produced a
novel construction of devices for carrying and adjusting the side-lasting fingers,
whereby they are firmly supported and readily adjusted.
I have made improvements in the organization of the complete machine, in its
construction, and in its various devices and combinations, whereby the functions,
separate and distinct and co-operative, are rendered effective for satisfactory work,
all of which I will now describe, and as illustrated in the accompanying drawings,
preparatory to a specific designation of the devices and combinations of devices
claimed as my invention.
The following is a description of the drawings of my invention as illustrated therein,
and as adapted to the forms of mechanism shown.

Figures 32, 33, 34, 35, 36, and 37 illustrate the progressive steps in the operation
of lasting the upper to receive the tacks.
A suitable frame A is constructed of such form and size as will support the working
parts of the organized machine, the cam-shaft B whereof is mounted in bearing-boxes a
at each end of the frame. Upon this shaft are splined two cams bb, of like con-
struction, but formed as rights and lefts, adapted to slide freely upon said shaft to
rotate with it, and to operate, respectively, the toe and heel clamping and crimping
mechanisms, as will be hereinafter described. At the top of the frame and upon
horizontal guideways c c¹, as seen in Figure 3, at each end thereof are mounted
two carriages D and D of like construction and adapted to slide upon said guide-
ways coincidently with the sliding movement of the cams upon their shaft. The
carriage D at the left carries the toe clamping and crimping mechanism, and
the carriage D' at the right carries the heel clamping crimping mechanism. A top
plate d d and two depending side plates d³ d² and d³ d³ compose each carriage, the
top plates being fitted to slide in the guideways c c', and forming the support for
the carriage in the frame, while the depending side plates support the carriage
laterally between interior projections of the side walls of the frame, as shown
in Figure 6.

page_text: Projecting horizontally from the lower inner end of the depending side plates d
of the carriage D₁ is a bracket e which has pivotally supported thereon the
adjustable last-supporting jack E, upon which the last is primarily supported, as
shown in Figure 3. Pivotally mounted in the upper end of the jack is a stud e¹,
that fits in a hole in the last and is made adjustable by the nut e³.
The last having been placed upon the jack, as shown in dotted lines in Figure 3,
it is clamped between a toe-clamp G, supported upon a vertical bracket g, rising from
the top plate d of the carriage D, and a heel-clamp H, supported upon a bracket A,
rising from the top plate d¹ of the carriage D', and the clamping is effected by the move-
ment of the carriages D and D' toward the last. The means for effecting these
movements of the carriages I will now describe.
Rigidly connected to the under side of the top supporting-plate d' of the carriage D₁,
is a horizontal rack-bar j, placed at the outer side of the depending side plate d
and pivoted to one of the depending side plates of the carriage D is a rack-bar j¹,
that extends over to the carriage D₁ and directly under the rack-bar j, the teeth of
the said racks extending toward each other. A pinion is secured upon the inner
end of a horizontal stud k¹, rotatively mounted in bearings in the side wall of the
machine, between the rack-bars, as shown in Figures 3, 6, and 23, and this pinion k
is operated by a hand-lever K, (seen in Figure 2) so as to give a uniform recipro-
cating movement in opposite directions to the rack-bars and through them to the
carriages DD to carry the toe and the heel clamps toward the last, and thus clamp
the same and to carry them away from the last after the shoe has been lasted.
The free end of the rack-bar 1 is supported upon a roll, mounted on the inner
wall of the frame, so as to maintain it in gear with the said lever-pinion k. This
pinion stud has at its outer en a conical hub which terminates in a screw-
threaded stem at the outer side of the frame, the taper of said hub standing outward
and upon which is mounted the hand-lever K. This hand-lever K is composed of
two parts and and the part * has a conical bearing that fits the conical hub ³,
and is frictionally clamped thereon by a nut 46, upon the screw-stem, thus tightly
locking the pinion and the hand-lover together. This way of connecting the hand
lever with the pinion k admits of the proper adjustment of the carriages with relation
to each other and to the last, and also with relation to a gauge I, fixed on the
frame, by which the heel and toe clamps are locked when clamped upon the last.
The part of the hand-lever is pivotally connected to the part by means of a
screw, and it will be seen that the part extends beyond the pivotal connection
and is engaged by adjusting-screws k situated in lugs upon the part k, so as to abut
against the opposite sides of the extended end of the lever part k, and thus allow of
a finer adjustment of the hand-lever with relation to the gauge I and its adjustable
stop than could be effected by the frictional conical bearing previously
described. This gauge as shown in Figure 2, is composed of a segmental strip of
metal placed upon the frame in the path of the hand-lever and is provided with a
series of holes, that are engaged by a spring-latch 8, Figure 1, upon the outer end
of the hand-lever, and so hold it in a desired position. These holes in the gauge are
so spaced with relation to each other that the movement of the lever from one hole
to another would move the toe and heel clamps just far enough to clamp the next
half-size last that is, the holes are graduated to half sizes of lasts.
To enable the operator to carry the clamping-lever to the proper hole in the gauge
to clamp the size of last he may be using, I have provided an adjustable
stop-block i. (Shown in Figures 1 and 2 and in detail in Figure 24.) This stop may be
of any suitable form, but as shown, it is a block of metal provided with a slot, to
fit over the gauge I, and is provided with a spring pin, to engage with the holes in the
gauge, and is released from said hole by pulling the knob. The lever can be moved
anywhere upon the gauge that it may be desired to stop it for the particular size of
last in the machine.
Referring now to the heel-clamp H, as shown in Figures 16 and 17 in detail, it is
composed of two metal side plates ½, hinged to a rear plate ', bent to conform to the
heel of the last. Fastened upon the inner sides of the side plates h and extending

page_text: around the inner surface of the rear plate, but at some distance therefrom, is a
rubber cushion h², against which the heel of the last is clamped. At the rear side of
this rubber cushion ³ is fastened a metal plate 3, having pivoted thereto two arms ht,
which extend through a slot in the rear plate h¹, and which are pivoted to arms *,
rigidly fastened to the plates h. When, therefore, the clamp is pressed against the
heel of the last, the cushion 2 will be forced back toward the rear plate h, and by
means of the pivoted arms, and the rigid arms, the side plates will be forced
in toward the last and thereby conform the counter and heel to the shape of the last,
as shown by dotted lines in Figure 16.
As a provision for allowing the clamp to adjust itself to the heel of the last, it is
pivotally mounted on the bracket he, as seen in Figure 17.
The toe-clamp G, previously described as being pivotally mounted upon the bracket g,
is shown in detail in Figures 13, 14 and 14", is composed of a metal bar g¹, bent over
at its upper end and formed into a semicircular widened part G, to engage with the
toe of the last. At its lower end it is provided with an adjusting-screw g², by which
pressure on the toe of the last is produced and regulated, and at or near the middle
of its length it is provided with two arms 93, which embrace the said bracket g and by
which said bar g' is pivoted thereto.
Referring to Figure 13, it will be seen that at the inner ends of the depending
side plates of the carriage D, and between them, is fitted a vertical slide 7 in
grooves in said plates, which has a horizontally-projecting bracket 12. The opposite
side of said slide at its lower end is provided with a roll, that engages with a cam b³,
and by which it is raised. It falls by its gravity. Mounted on the bracket is a
short screw-stud, and telescoping with said stud is a tube 1, which passes through
a guide-arm, extending from the upper end of the slide, and in the upper end of
this tube is fitted the supporting screw-stem (one) of the toe-rest g'. The tube 1³
contains a spring 2, by which it has a yielding support upon the screw-stud 1, as
seen in Figure 15. This tube is provided with a vertical slot 3 at its lower end to
receive a pin 4 on the screw-stud 1, whereby the tube is held in proper relation to the
screw-stud against the force of the spring tending to separate them. This relation is
maintained by a screw-sleeve 5, on the lower end of the tube 15, and the pin 4,
abutting against said sleeve, so as to allow this tube to yield under the action of the
toe-rest when the slide is raised. The limit of the yielding movement of the tube 1
is determined by lock-nuts 6 on the screw-stud 14, and the tension of the spring is
adjusted by sleeve 5. The toe-rest is pivotally connected at g, with its supporting
screw-stem 1, so as to allow it to properly adjust itself to the last, and the said screw-
stem 1 is provided with lock-nuts 9, by which to support the said screw-stem within
the end of the tube and adjust it to the proper height thereon,
The toe-rest is preferably made of rubber, of V shape open at both ends. Its inner
sides 77 terminate in a longitudinal bottom groove 7, and are slightly convex
lengthwise and terminate in a downwardly-inclined concave flaring inner end, as seen
in Figure 14, so that it will conform to the toe and instep of the last and strain
and mould the upper thereon as it is raised against the toe-crimping mechanism,
against which the last is firmly held by the pressure of the spring in the tube. At
the inner side of the toe-clamping bar g is pivotally hung, by means of a lug 8,
Figure 14, a tripping bar g, against the foot of which the adjusting-screw
abuts. At its lower end this tripping bar is formed with a toe-shaped projection that
abuts against the inner side of a slide g*, fitted in vertical guides in the inner wall of
the bracket g, as seen in Figures 13 and 14. This slide 9 has an enlarged foot
part, which is connected by a screw-post 9 to the arm of the slide 1, said post
entering a screw-tap in the slide-foot, and has a nut 10 by which to adjust the
slide 9 in proper relation to the tripping-bar gl. Now by turning the screw
the clamping end of the toe-clamp G will be caused to move toward or away from the
last, as may be desired to set the toe-clamp to act with more or less force against the
last. In the operation of this clamping and tripping device the cam 62 causes
the slide to rise and with it the slide 9, which will free the latter from the toe of
the tripping-bar and allow the lower end of the said tripping-bar to swing under

page_text: the said slide g and thereby release the toe-clamp. This releasing of the toe-clamp
allows the toe-wiper m which is carried by the slide to rise free of the toe-clamp
and to draw the upper tight around the toe of the last, as I will now describe. This
toe-wiper m is composed of a thin plate of spring metal, bent to conform to the shape
of the last at the toe, but is a little smaller than the toe, so that when it is pressed
up around the last it will bear sufficiently tight against the upper to draw it firmly
around the last. The edges of the toc-wiper are made slightly rounded or flaring, so
as not to scratch or cut the upper. Riveted on the back of the wiper-plate is a strip
of metal m that fits in a slot m³, Figure 14, in the foot of the slide g, and is held in
place by a spring m³, secured upon the slide g, so that its upper end extends over
the said slide and projects through a slot in the back of the wiper, (seen in Figure 14)
and is slightly book-bent to take hold of the wiper and retain it in place, while at
the same time permitting of its ready removal when a larger or smaller wiper is
desired.
Referring to the co-operation of the toe-clamp G and of the toe-rest g' at the time
the latter is raised the toe-clamp is released from its lock and is caused to fall back by
gravity due to the manner in which it is hung by its pivot-arms, and in thus falling
back at the top it swings forward at its lower end, carrying with it. the lower end of
its hanging trip-bar g. The relation of the toe-rest support to the toe-clamp is such
that the latter is held in position by the co-operation of the toe-rest support and
the hanging trip-bar when the toe-rest support is down, and the toe-clamp is released
when the toe-rest rises.
In Figures 13 and 14 the toe-clamp G is shown in its locked clamping position.
Referring now to the toe and heel crimping devices, they are of similar construction
and are carried upon the under sides of top plates N and N¹, which are mounted upon
the supporting-plates d and d of the carriages D and D1, as shown more clearly
in Figures 3 and 13, one of said plates being shown in top view in Figure 10. These
top plates are supported for adjustment in relation to the last, as I will now state.
The front ends of these top plates are mounted on posts n, (see Figures 3 and 4) that
are provided with adjusting-nuts n' so as to raise and lower said plates to the proper
level relatively to the last. The connection of these posts with the top plate is
by ball-joints n, Figure 4, so as to allow said plates to be tilted from the rear end so
as to bring the crimping-fingers 0 carried by said plates, in proper line with the
spring of the last. This tilting of the top plates is effected by means of a screw-
threaded barn, pivotally connected to the outer end of each of the top plates and
provided with
hand-screw, as seen in Figure 3, having a bearing upon the
supporting plate of the carriage.
Fitted to slide in a groove O', on the under side of the top plates N and N¹, is a
bar O, having at its inner end a projecting lug or nose O³, under and against which
the last is pressed by the toe-rest g'. Now, looking at Figures 10, 11, and 12, it will
be seen that this bar 02, has pivoted at its inner end, at O, the crimping-fingers 0,
which approximate in form to a crescent. These crescent fingers are provided with
arms or lugs O' which are pivoted to links 0%, which are at their other ends pivoted
together and upon a plate 07 which is fitted to slide in guideways 08 on the under
side of the top plate, as seen in Figures 4 and 13, so that the movement of said
plate will cause the fingers to have a sweeping or circular motion over the toe of the
last and thereby crimp and lay the leather, as seen in Figures 36 and 37.
Projecting downward from the under side of the plate O' of each carriage D and D₁
is a lug 0, Figures 2, 3, and 13, to which is pivoted one end of an adjustable link 01°
the other end of which is pivoted to the upper end of a rocking lever 01, which is
mounted in vertical position between the depending side plates of the carriages on a
cross-stud 0" (Seen in Figure 3.) The lower ends, of these levers 0" are forked
and connected at 112 to a small cross-bar 123, fitted to slide in guideways on the inner
walls of the depending side plates d', d of the carriages D, D and a roller 01,
mounted on a short stud on the under side of said cross-bar 123, is adapted to work in
the cam-groove 6, of the right and left cams band, so that these levers 0" operate
the said plates 07 of both carriages simultaneously.

page_text: The adjustments made by the screw-links 010, are to adapt the heel and toe-crimping
fingers to suit lasts having different widths of heels and toes by increasing or
diminishing the extent of the movements of said fingers.
Projecting downward from the outer end of the bar 0 is a lug 0" to which
is pivoted the upper end of a link 015, the other end of which is pivoted to the upper
end of a rocking lever Oe, which, like the lever O", is mounted on a cross-stud "0",
between the depending side plates of the carriages. The lower ends of these levers (1
are forked and connected at 13 to a small cross-bar 14° fitted to slide in guide-
ways on the inner walls of the depending side plates d', d³ of the carriages D D₁, and
a roll O mounted on a short stud on the under side of said cross-bar 14°, is adapted
to work in the cam-groove 6 of the right and left cams 6 and 6', so that these
levers O operate the said bars 0% of both carriages simultaneously.
As the structure and operation of the heel and toe crimping mechanisms are
identical, it is only necessary to illustrate in detail, the crimping devices of one of
these mechanisms in their relation to the last, and for this purpose I have shown in
enlarged views the toe-crimping devices in Figures 10, 11, and 12, and the last in
dotted lines, in which Figure 10 shows the crimping fingers and the slide bar 0*
in their positions when not operated by their respective cams. In Figure 11 the
crimping-fingers and the slide har are shown in their first movements together
toward the toe of the last to bring the points of the crimping-fingers nearer to each
side of the last and the projecting lug or nose of the slide-bar carrying the leather
over the toe. In this movement it will be seen that both the cams 63 and 6* operate
simultaneously and with the same movement upon both the rocking levers "
and O, and thus move both the slide-bars 02 and the slide-plates 0' together
without changing the relative positions of either.
In Figure 12 the crimping-fingers are shown as having been operated by the
forward movement of their connected plate to cause them to sweep with a circular
closing movement over the last to crimp and lay the edges of the upper thereon, and
to maintain such position during the operation of tacking the shoe. As this closing
action of the fingers over the toe upon the edges of the upper is liable to cause
puckers at these points and interfere with the smooth laying of the edges, I have
provided auxiliary side-lasting fingers P P (shown in Figures 1, 5, 10, 12, and 33,)
which I will now describe. Referring particularly to Figure 5, the said fingers are
seen as being formed of flat pieces of spring metal, carried upon the upper ends
of levers P¹ P¹, which are pivotally connected to the inner ends of the depending side
plates of the carriage D, and extend down to and connect by rolls with face
cam-grooves P2 P² of like form, and both formed one within the other upon the
cam of the cam b and to cause the said fingers to move over the last, as seen
in Figures 11 and 33, just before the crimping-fingers close, and to move away from
the last after the crimping-fingers have closed, as seen in Figure 12. In this
preliminary laying movement the side fingers P P are so formed as to allow the
crimping-fingers to pass under them. About the same time the closing movements of
the crimping-fingers occur, the side rubbers or wipers operate to bring up the upper
and draw and strain it over and about the bottom of the last, as I will now
describe.
Referring particularly to Figures 6, 7, 18, 19, and 20, the said wipers or rubbers
are shown as being formed of separate and distinct parts used in pairs for each side of
the last. They are preferably each formed of a single piece of leather, the part
operating upon the hollow or shank sides of the last being wider and longer than the
part operating upon the swell of the last; but both are carried by a lever-frame, and
the lever-frame of each set is supported and operated simultaneously. These lever-
frames 1 will now describe preparatory to describing the particular_means for
mounting the rubbers to permit of their yielding and rubbing action. Each lever-
frame consists of arms QQ', connected in pairs about the middle of their length by a
cross-bar 11. One of these lever-arms Q is made longer than the other and extends
down, and is pivotally connected at its lower end to a cross-head Q, fitted to slide
vertically in guideways 12, fixed to and depending from the sides of the frame of the

page_text: machine, as seen in Figure 6. A bolt 13 is mounted in these lever-arms, above their
connecting cross-bar 11, and upon this bolt is pivotally mounted the support for the
large wiper, and which is preferably made of a U-shaped bar Q³, with its ends loosely
mounted upon each end of the said bolt, as seen in Figure 20. In the upper end of
this wiper-support is socketed a screw-stud 14, provided with an adjusting-nut 15,
which rests upon the top of this wiper-bar Q³, and rising from this screw-stud 14, and
preferably integral with it, is a plate 16, curving over toward the last with a convex
edge conforming to the hollow of the last, and having a width suited to the hollow
side of the last. Upon and over the upper curved edge of this plate the leather
rubber Qis riveted, and extends down in a substantially vertical position and
slightly tapering from the top, and is secured in a clamp pivotally mounted in the
wiper-bars Q and stretched by a coil-spring 17, which connects the lower end of the
rubber to the cross-bolt 13 of the lever-frame and renders the rubber flexible at every
point. The clamp for the lower end of the rubber Qis composed of two plates 18
and 19, between which the small end of the rubber is firmly clamped over and upon
the edge of the inner plate 19 by screws 20, passing through each end of the
outer plate 18 into the edge of the inner plate. This inner plate is secured edgewise
in the slotted end of a screw-rod 21, the other end of which is held in a cross-bar 22,
loosely mounted in bearings in the sides of the U-shaped wiper-bar Q the said
screw-rod 21 being supported on said cross-bar by a nut 23, by which the screw-rod
can be set out or in. By this means of mounting the wiper it can be adjusted
vertically by the screw and nut 14 and 15; it can be adjusted out or in at its lower
end by its supporting screw-rod 21; it can yield along its length by reason of the
freedom of its supporting screw-rod to rock with its supporting cross-bar in its
bearings in the sides of the U-shaped bar, and it is constantly strained over the said
rocking support by the pulling action of the spring 17. It is perfectly adapted for
different forms and for right and left lasts.
Supplementing the function of the rubber to yield as stated, it is firmly but yieldingly
pressed forward and held against the last by a spring 24, extending from the upper
end of one of the arms of the lever-frame to the upper end of the U-shaped bar Q³,
and supported by a rod n² and nut n², which adjustably connects the rubber-support
with the lever-frame. This allows the rubber-support to yield in the arc of a circle
upon its bearing rod 13, while the rubber itself has an independent yielding function,
as stated, whereby it is adapted to act with a moulding pressure to hold and
strain the upper as it is raised in contact with the hollow or shank side of the last.
It may be readily replaced when worn out by a new one. Co-acting with this
flexibly-acting rubber for the shank, I provide a small rubber Q, having a flat and
preferably non-yielding surface adapted to operate upon the toe or the swell part of
the last. It is formed of a piece of leather riveted to a flat plate provided with a
round stem 25, (see Figure 18) secured in a socket 26, formed in the upper end of
an arm 27, mounted loosely upon the rod 13, and which is constantly pressed forward
at its upper end by a spring 28, connecting its upper end to the upper end of one
of the arms of the lever-frame, the said spring being supported by a rod To and nutr³,
which adjustably connect the arm 27 with the lever-frame. A spring-pin fastens
the shank of this small rubber in its socket, so as to permit of its easy removal and
replacement. This toe-operating wiper part is mounted so as to set back from the
face of the shank-operating wiper part to suit the swell of the last; but they both
move so as to act together. In the starting of these wipers they are brought against
the sides of the upper, below the top of the last, as seen in Figure 34, and are
carried up a little below the top of the last, as seen in Figure 35, so as not to
interfere with the action of the side-laying fingers, as I will now describe.
Each arm of the lever-frame is formed with a cam Q, as seen in Figures 7 and 18,
as inclining upward and inward on the outer edges of and about the middle of the
length of the arms, so as to act against rolls Q7, which are mounted upon short shafts
supported in bearings in the ends of brackets Q8, which extend inward from the
inner walls of the opposite sides of the frame. At a point centrally and near the
top of the cross-head Q³ is mounted on its side a roll "Q", which works in a cam-

page_text: groove Q10, (shown in Figure 9 and in dotted lines in Figure 7) and which is fixed
upon and rotated by the cam-shaft. As seen in this figure the wipers are in their
normal open positions so that the rotation of the said cam Q will cause the cross-
head Q to rise, and simultaneously the cams Q of the lever-arms will be caused to
ride upon the rolls Q7, and thus force the wipers inward upon the sides of the upper,
for the purpose stated. The wiper-arms stand inclined inward from their pivotal
connections, so as to overhang their lever carrying frame, and hold the acting
wiper-surfaces in vertical positions in relation to the last, and particularly is this
important in maintaining the strap-wiper in position to have its upper end act upon
the shoe-upper as it is moved inward and upward upon the shoe-upper, so as to
stretch and lay the latter well over the edges of the inner sole, and there hold it
for the action of the crimping-fingers. This rubbing and smoothing action upon
the side of the shoe upper and upon its upper edges over the edges of the inner
sole could not be obtained if the straps were pulled away from the last at their
upper ends.
Referring now to the side-lasting fingers R for laying the edges of the upper, and
particularly to Figures 6, 25 and 26, it will be seen that they are arranged upon the
carriages R R at each side of the machine, so as to stand crosswise above the top of
the frame, on a level with the bottom of the last, and are moved toward and
from the same. These fingers are formed of long narrow pieces of spring metal,
arranged in parallel relation, separated a distance about equal to their width and of
sufficient number to fill the space over the last between the crimping-fingers when
the latter are in their closed positions, as seen in Figure 37. They are supported at
two points upon their carriages, which latter are formed of a horizontal plate and
vertical end plates and fitted to slide in ways R' on the top of the frame of the
machine, which at this point is made wider than the end portions of the frame, as
shown in Figure 1, so as to accommodate the length of the fingers and the movements
of the carriages. These fingers R are supported independent of each other at their
outer ends and at the outer side of the carriage by means of L-shaped metal holders R³,
the vertical part whereof has a hole within which is snugly fitted the round end 29 of
the shank of the finger, where it is fastened by a key 30 pinned in said holder so as
to allow the finger to be turned. In the horizontal part of this angle-holder R is
fastened a screw R, which passes down through a screw-threaded hole in the top of
the carriage and depending from said angle-holder is a guide-stud R' which passes
down through a hole in the top of the carriage. This construction allows the vertical
adjustment of the outer end of the finger and keeps the angle-piece in proper relation
to the finger. At the inner side of the carriage the fingers are also supported
independent of each other by means of sockets or boxes R each one placed between
two screws and having square openings, within which the square shanks of the fingers
are fitted. These socket-boxes are formed at each side with approximately spherical
cavities 32, (seen in Figures 28, 30, and 31,) whereby they are seated and adjustably
supported upon correspondingly-formed shoulders 53, formed upon the shanks of
screws R' which pass down through screw-threaded holes in the top of the carriage.
By this construction the acting ends of the fingers are adjusted vertically, while the
socket boxes by this adjustment permit the fingers to be automatically turned. These
adjustments are shown in Figure 26, wherein is seen the socket-boxes set so as to
support the fingers on a side incline, and the conical form of the screw-shoulders,
upon which the socket-boxes are supported with a ball joint seating, so that they are
confined between and can be turned upon the shoulders of the screws. The semi-
spherical cavities 32 extend about balf the thickness and open at the bottom of the
box and merge into semicircular cavities 34 in the upper half of the box, which
exactly fit the necks 35 of the screws above their conical shoulders, while the
neck of the screw terminates in a circular collar 36, which exactly fits into a
semicircular recess 37 iu the top of the box around the side recess 34, whereby the
box is permitted to move over the screw-collar in adjusting the box on an incline.
These top recesses for this purpose are made with inclined bottoms, as shown in
Figure 30, and in thus allowing the turning of the boxes the said collars also serve

page_text: wheel D on the fixed clutch part of the power-transmitting shaft and a brake-
arm V fixed upon the stud of the clutch-lever, the relation of the brake parts
being such that when the stop dog enters a notch in the gear-wheel rim the brako-
arm will be instantly pressed up against the brake-wheel, and thus relieve the shock
and hold the machine out of gear.
In Figure 22 I have shown the notched rim and the notches therein as being
bevelled at their ends approaching the dog, so that in stopping the machine the dog
will easily enter the notch, and in starting the machine the dog is withdrawn by the
treadle clear of the shoulder of the notch.
The machine being at rest and all the lasting parts open, the last, with the upper
and the inner sole thereon is placed upon the heel-pin of the jack, and the operator
raising the hand-lever, operates the heel and toe carriages to bring the heel-clamp and
the toe-rest in contact with the last to firmly clamp it in position during the operation.
In this clamped position the parts are locked by the spring-pin of the hand-lever
entering the proper hole in the gauge, which is determined by the gauge-stop limiting
the movement of the hand-lever. During this operation the machine is locked out
of power by the stop-dog. The operator then depresses the treadle which withdraws
the stop-dog, engages the clutch, and the machine starts. The cams and then
act by the cam parts (shown in Figure 3) to move the heel and toe crimping devices
forward in the relation to the last shown in Figure 11. At this moment the auxiliary
side fingers are caused to close over the toe by the cams, (shown in Fig. 5) and
immediately following this movement of the auxiliary side fingers the toe-wiper is
caused to rise and strain the upper, so as to mould it around the toe of the last by the
edge-cam 62. (Seen in Figures 3 and 5.) Simultaneously with the action of the
toe-wiper m the toe-rest is also caused to rise, and by its compressing action
upon the upper across the instep and ball of the top of the last draws the upper
tightly to conform to the top of the last. As soon as the toe-rest comes in contact
with the last, it is depressed by the latter for about an inch against the tension
of its supporting-spring 2, until the sleeve 5 strikes the nut 6, when the toe-rest
will be carried up by the cam so that its sides 7 will spread over the upper and
strain it over the last. In this action the groove 72 allows the sides 7 to open
slightly as they ride up over the last, while the toe-rest. tilts upon its pivot go, to
allow its concave flaring end to conform to the instep of the last. During this
operation the side rubbing or wiping devices (shown in Figures 7, 18, 19, and 20)
are caused to rise and strain and carry the upper up toward the bottom of the
last, so as to draw the upper perfectly tight around the last by the action of the
(Shown in Figures 7 and 9.) During this operation the side-lasting fingers
are caused to move forward and over the bottom of the last, carrying the edges
of the upper over the bottom of the last by the action of the cams and cross-head.
(Shown in Figures 6 and 8.) During this operation the heel and toe crimping devices
are caused to close by a sweeping circular movement, carrying the upper over the
inner sole at the heel and at the toe of the last, as seen in Figures 12 and 37,
by the action of that part of the cams 636 seen in Figure 21.
cam.
It will be understood that in the several and distinct steps of the lasting operation
above stated there are no two movements that are necessarily completed together;
but their operation is made continuous by the successive following of the cams
during the operation of the machine, as indicated by the space between the stop-
notches from to in Figure 22. At this point the automatic stop device is
brought into action by the stop-dog sliding into the stop-notch in the annular
gear-rim, which stops and locks the machine out of action. The upper is now
ready to be fastened to the inner sole, which may be done by tacks, as stated, or
in any desired manner. After the upper is fastened the operator then placing his
foot upon the treadle starts the machine, the operation of which brings the stop-
notch into position to be locked by the stop-dog, but during which operation the
crimping-fingers are opened, as seen in Figures 11 and 10, which gives the operator
a chance to see if the edge of the upper is fully fastened at the heel and toe,

brings the stop-notch into position to be locked by the stop-dog, which brings the
machine to its normal condition.
