Improvements in Crimping Machines.
I, JOSEPH COLLIER LOCKETT, of 21 Mechanic Street, Allston Dist., Boston,
in the County of Suffolk, State of Massachusetts, United States of America
Machinist, do hereby declare the nature of this invention to be as follows :-
My invention relates especially to a machine for crimping the uppers of boots
and shoes; and it consists in certain novel features hereinafter set forth, the object
being to produce a simpler, cheaper and more effective device of this character
than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation:
The entire machine is mounted upon a base or standard on which an upright or
pillar is disposed. A shaft provided with fast and loose pulleys, is journalled in
said upright, the opposite end of said shaft being provided with a pinion.
A vertical track or way, is formed on one side of the upright, and a shaft is
journalled in the top of said upright and projects through said ways.
On the shaft, a crank gear is mounted the said gear meshing with the pinion
above mentioned.
A block is fitted to slide in the said ways and a rod pivoted eccentrically on the
gear connects it with the said block, the said gear driving the block in its ways, in
the ordinary manner of crank mechanism.
At the rear of the way, and parallel therewith there is a vertically arranged
groove formed in the upright.
The crimping blade is secured by screws to the lower end of the sliding block,
and projects outwardly at the front of the machine.
A vertically adjustable arm projects rearwardly from the crimping blade, and is
provided at its outer end with a roll or wheel which works in the vertical groove of
the upright said arm is adjustable on the blade by means of screws which pass
through the slot in said arm into said blade.
The table of the machine is mounted horizontally on the top of the body or
pillar and on a standard at one end of said table a horizontally swinging lever is
pivoted. The said lever is provided at its outer end with a vertically arranged
block which registers with the upright groove, and which is normally disposed in
the path of the roll or wheel hereinbefore mentioned.
On the forward end of the standard a hub is formed through which a rod is
fitted to slide longitudinally; said hub being chambered around the said rod.
The other end of the rod is secured by a nut which is screwed thereon, said nut
being of a size. suitable to slide in said chamber.
Between the nut and bottom of said chamber a push-spring is disposed around
the said rod. To the inner end of the rod, a crimping jaw is secured.
The forward end of the swinging lever hereinbefore mentioned plays loosely on
the rod and between said lever and the jaw a push-spring is interposed.
Registering with the jaw there is a companion crimping jaw, which is mounted in
the same manner as the hub before referred to, its sliding rod being spring-pushed
and provided with a nut.
The two jaws have their upper edges formed on a curve conforming to the shape
of the curve of the crimping blade.
On the inner or working faces of the jaws there are formed a series of corrugations
which follow the line of curve of the edge of said jaw.
An angular rod projects horizontally from the front of the table and fitted to

page_text: slide on said rod there is a curved plate said plate being slotted and having its
curve following the outline of the tops of the afore mentioned jaws.
A stop on the angular rod limits the movement of said plate laterally and when
in engagement with said stop its slot will register with the opening between
the jaws.
.
The curved plate is designed to feed the upper leather onto the jaws and avoid
the danger of injury to the hands of the operator from the crimping blade.
In use the leather to be crimped is disposed on the feed plate or carriage, which
is moved from right to left by the operator.
Power being applied to the main shaft the sliding crank-actuated block is set
in motion forcing the blade through the carriage slot and between the jaws. As
the block descends, the wheel engages the block on the lever, throwing that end of
the lever outward.
The opposite end of said lever encircling the rod, drives the spring against the
jaw jamming said jaw tightly against the blade.
The tension of the companion jaw may be regulated at will by the force of its
spring.
Guide rods on the hubs slide in the jaws and serve to prevent lateral movement
thereof.
Corrugated inner faces of the jaws engaging the leather retard the downward
motion thereof and cause it to be formed or crimped into a shape corresponding to
the curve of the crimping blade, in a manner which will be understood by all
conversant with such matters without a more explicit description.

Improvements in Crimping Machines.
I, JOSEPH COLLIER LOCKETT, of 21 Mechanic Street Allston District Boston,
in the County of Suffolk, State of Massachusetts, United States of America,
Machinist, 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 :-
My invention relates especially to a machine for crimping the uppers of boots
and shoes; and it consists in certain novel features hereinafter fully set forth and
claimed, the object being to produce a simpler, cheaper and more effective device of
this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation:
In the accompanying drawings
Figure 1 is a side elevation of my improved crimping machine;
Figure 2 is a front elevation of the same partly in section, the standard of body
being removed.
Figure 3 is a horizontal section taken on line x, x, of Figure 1;
Figure 4 is a face view of one of the jaws; and
Figure 5 is a transverse section of the same.
Similar letters and figures of reference indicate corresponding parts throughout
the drawings.
A represents a base or standard of the machine on which an upright B is
arranged. A shaft b, provided with fast and loose pulleys d, d', is journalled in
said upright, the opposite end of said shaft being provided with a pinion f.
A vertical track or way C, is formed on one side of the upright, and a shaft g,
is journalled in the top of said upright and projects through said ways. On the

page_text: shaft g 18 mounted a crank gear D, which meshes with the pinion f above
mentioned.
A block E, is fitted to slide in the said ways C, and a rod h, pivoted eccentri-
cally on the gear D connects it with the said block, the said gear driving the block
in its ways, C, in the ordinary manner of crank mechanism.
At the rear of the way C, and parallel therewith is a vertically arranged groove h³,
formed in the upright B.
The crimping blade H, is secured by screws i, to the lower end of the sliding
block E, and projects outwardly at the front of the machine.
A vertically adjustable arm j, projects rearwardly from the crimping blade H,
and is provided at its outer end with a roll or wheel m, which works in the vertical
groove h of the upright B; said arm is adjustable on the blade by means of
screws, which pass through the slot in said arm into said blade.
The table I of the machine is mounted horizontally on the top of the body
or pillar A, and on a standard p, at one end of said table a horizontally swinging
lever gis pivoted. The said lever is provided at its outer end with a vertically
arranged block
which registers with the upright groove h¹, and which is normally
disposed in the path of the roll or wheel, m, hereinbefore mentioned.
On the forward end of the standard p, a hub t, is formed through which a rod
is fitted to slide longitudinally; the said hub being chambered at to (see Figure 2)
around the said rod. One end of the rod is provided with a nut Z which is
screwed thereon, said nut being of a size suitable to slide in said chamber.
Between the nut and bottom of said chamber a push-spring 15 is disposed around
the said rod. To the inner end of the rod v, a crimping jaw P, is secured.
The forward end of the swinging lever q plays loosely on the rod r, as best
shown in Figure 3, and between said lever and the jaw P, a push-spring 16, is
interposed.
Registering with the jaw P, there is a companion crimping jaw P¹, which is
mounted in the same manner in the hub t', its sliding rod, being spring-pushed
and provided with a nut z¹.
The two jaws P, P' have their upper edges formed on a curve at 17, conforming
to the shape of the curve 18, of the crimping blade H.
On the inner or working faces of the jaws P, P₁, there are formed a series of
corrugations 20 which follow the line of curve of the edge of said jaw.
An angular rod 25, projects horizontally from the front of the table I, and fitted
to slide on said rod there is a curved plate M, said plate being slotted at 26, and
having its curve following the outline of the tops of the jaws P, P.
A stop 27, on the angular rod 25, limits the movement of said plate laterally and
when in engagement with said stop its slot 26, will register with the opening between
the jaws P, P.
The curved plate M, is designed to feed the upper leather on to the jaws and
avoid the danger of injury to the hands of the operator from the crimping blade.
In use the leather to be crimped is disposed on the feed plate or carriage M, which
is moved from right to left by the operator, as seen in Figure 3.
Power being applied to the main shaft b, the sliding crank-actuated block E, is
set in motion forcing the blade H, through the carriage slot 26, and between the
jaws P, P. As the block E descends the wheel m engages the block r, on the lever q,
throwing that end of the lever outward.
The opposite end of said lever encircling the rod v, drives the spring 16 against
the jaw P, jamming said jaw tightly against the blade H.
The tension of the companion jaw P with the jaw Pinay be regulated at will by
the force of its spring 15.
Guide rods 30 on the hubs t t¹ slide in the jaws and serve to prevent lateral
movement thereof.
Corrugated inner faces of the jaws engaging the leather retard the downward
motion thereof and cause it to be formed or crimped into a shape corresponding to

page_text: the curve of the crimping blade, in a manner which will be understood by all
conversant with such matters without a more explicit description.
