page_text: ROBERT MARSHALL of the City of Hamilton in the County of Wentworth,
Province of Ontario, Canada, do hereby declare the nature of this invention to be as
follows:-
My invention consists of a device for the crimping of leather for the uppers for
boots and shoes, the machine working automatically so that when a flat piece of
leather oval in shape is placed between springs and sliding double moulds and
operated upon by the mechanism of the machine until the centre of the double moulds
arrives in the centre of the stationary double mould and remaining there until the
trix performs a full stroke carrying the leather with it.
When the said trix is brought back from out of the stationary double moulds and
said sliding moulds the latter quickly moves on again to the centre of the stationary
mould and is repeated at every full stroke of the trix.
During the time the double moulds are stationary a double press plate is brought
down and bears on a spring (shaped as the double mould) which bears on the leather
by the pressure of the said press plates, remaining stationary during the time the
trix is going down and partially up, then quickly moves up while the double moulds
slide horizontally, the same being repeated at every stroke of the trix, all operating
automatically by the mechanism of the machine.
An under pressure is brought to bear against the trix to release the leather from
same.
Guiding the downward movement of the trix which works in slides is a matrix
the top of which is shaped to suit the bottom shape of the trix both moving
parallel.

A Machine for Crimping the Leather Uppers for Boots and Shoes.
I, ROBERT MARSHALL, of the City of Hamilton, in the County of Wentworth,
in the Province of Ontario, Dominion of Canada, 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:-
The nature of my invention consists of a device for crimping of leather uppers for
boots and shoes. The machine works automatically so that when a piece of flat
leather oval in shape is placed between springs and sliding double moulds attached
together, allowing space for said leather, the moulds that slide are operated upon by
the mechanism until the centre of the mould arrives in the centre of a double
rigid mould and remains there until a trix performs a stroke carrying the leather
with it.
During the time the sliding moulds are stationary, a double press plate is brought
down and presses slightly on the said springs during the time the trix is operating,
then slides up and also the trix, while the moulds slide horizontally to the next opening
of said mould, this is repeated at every stroke.
Against the interior sides of the rigid moulds is a thickness of rubber, and in
front of each rubber is a metal plate with corrugations with space between the
corrugated plates to allow the trix with leather to pass, and immediately beneath
these plates and parallel with the sides of the trix are two rubber rollers one
on each side, the face of each to run against the leather upper when coming down
with the trix thus tightening, smoothing and giving an even surface to the said
leather.
When the trix is part way down it is met by a matrix parallel with the same, and
is for the purpose of forming the leather, keeping the same in position and crimping
it into a seamless crimp.
Reference being made to the accompanying drawings, in which;
Fig. 1. is a side elevation of the machine embodying my invention, the sections of
the bevel and spur wheels being shown, and one half of the rigid mould is taken
away to show the matrix bolted to its rod, the outline of the trix being the same as
the outline of the lower part of the press plates therefore hid from view it being in
the centre of the two press plates.
Fig. 2. is a front elevation of the same, horizontally, the trix rod broken, and
the trix and press plates taken away, the pitch lines of bevel and spur wheels are
shown, sections of rigid double mould, rubber rollers, double sliding moulds with
springs, corrugated plates with rubber backing; through the centre line of cavity
of moulds.

page_text: In the drawing, A is the metal frame of the machine, together with its front
legs A¹, their brace A², hind legs A³, bed plate A', hind supporting bracket A³, spur
wheel bearing A, and the bevel wheel shaft bearing A', should be substantially
constructed of metal, and bolted together to resist the vibrations of the operating parts
of the machine.
B. B. are the fast and loose drive pulleys, supported by the bracket B¹ which is
bolted to the said frame; B2 is a forked rod attached to the foot lever B³ by means
of levers B' and fulcrum B' and are for the purpose of belt shifting.
The leather is placed between the springs and the sliding mould C which move
horizontally in the fixed groove 02 and on the fixed bar (3 by means of the levers D,
connecting (and nuts D2) with the double screw shaft D' which reciprocates the
same, the said shaft being driven by the bevel wheel D³ on shaft D³.
The trix E at the lower end of its rod E' receives its motion by the stud E2 in the
bevel wheel E³ forming a crank, the said stud working in the longitudinal slotted
bar E, J are the press plates which slide in the rigid guide J* and receive their
reciprocating motion together by means of their rods J' being attached to a pin or
stud J working in the groove forming a cam J³, on the face of the bevel wheel E³;
the trix in passing through the sliding moulds and the rigid moulds F encounters the
matrix I, which is between the two corrugated plates H, the said matrix forming and
pressing the leather against the said trix, reciprocates in the guides I², and receives
its motion by means of the crank K which is keyed onto the lower end of the bevel
wheel shaft in bearing A', thus transmitting power to the spur wheel A8 in
bearing A, the pin of the crank is connected to said spur wheel and also between
spur wheel and crank, it revolves in the longitudinal slide bars L, the under bar of
which is the top cross bar of the matrix rod I', and at the extreme ends of these
slide bars is a bolt which passes through both bars and provided with a coil spring S¹,
for the purpose of giving and allowing tension to the matrix when in contact with
the trix.
The rubber rollers R, revolve in the bearings R¹, each having a small spur wheel T
keyed on its shaft and driven by the small spur wheel T¹, each wheel shown by a
broken pitch line in fig. 2, the shaft U of the driving wheel T¹, has a pulley U1
which is driven by belt from pulley V on the shaft V₁, this shaft is supported in the
bearings on the two brackets V2 having a small spur wheel V* on its upper end
and driven by the large spur wheel A³, on the shaft in bearing A.
The surface plates N attached to arms M, are for the purpose of gripping and
securing each leather crimp from the trix before rising, deriving their power from
the double screw shaft 0, with traversing nuts P, the fulcrums S of said arins being
at the lower end of the guide bar 12 this shaft receives its motion from the bevel
wheel D at the lower end of shaft D³.
It will be perceived by the drawings how motion is transmitted from one part of the
machine to another part, the first pinion bevel wheel S3 and the driver of bevel
wheel E³, is keyed on the shaft of drive pulley B, thus giving motion to all tho
mechanism of the machine as before described.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st. The combination of the rigid moulds F secured to the metal frame A,
and provided with the corrugated plates H with rubber backing, double sliding
