Machines
or Apparatus, chiefly Designed for Making
Metallic Shanks for Boots or Shoes.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for IMPROVEMENTS IN COMBINED PUNCHING CUTTING AND
"
STAMPING MACHINES OR APPARATUS CHIEFLY DESIGNED FOR MAKING METALLIC
SHANKS FOR BOOTS OR SHOES " 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 more especially to that class of machines or apparatus
which are employed for making metallic or sheet metal shanks for boots or shoes,
and it consists in a novel construction and arrangement of the parts as hereinafter
more fully set forth and described, by which a more desirable and effective device
of this character is produced than is now in ordinary use.
The nature and operation of the improvements will be readily understood by all
conversant with such matters from the following explanation.
In the accompanying drawing: :-
Figure 1 is a front elevation of my improved machine.
Figure 2 is a side elevation of the same, certain parts being shewn in section.
Figure 3 is a plan or top view of the framework including the base or bed and
the sides or uprights.
Figure 4 is a plan or top view of the follower or cross-head to which the knife
is attached; and
Figure 5 is a plan or top view of the knife and the clamp by which it is attached
to the cross-head.
.
Like letters of reference indicate corresponding parts in the different figures of
the drawing.
a, a indicate the bed-piece and b, b the uprights or standards of the machine.
Mounted horizontally in the upper part of the standards b, b, there is a crank-
shaft m provided with a pitman-rod n; and fitted to work vertically in ways l, l;
on said standards is a follower or cross-head c.
[Price Gd.1

page_text: The cross-head is concaved on its upper side and provided with two inwardly
projecting arms q which are respectively concaved on their lower sides, their inner
ends being arranged to overlap the outer ends of the T-head on the lower end of
the pitman n, thereby jointing said pitman to the cross-head..
. A horizontally arranged knife d is securely attached to the lower side of the
cross-head by the clamp o and screws e, said knife being rendered vertically
adjustable by the screws p. Projecting from said head in front of said knife
are two arms each carrying a punch f, the punches being rendered adjustable by
suitable set-screws.
A horizontally arranged knife g secured by the screws his disposed in the bed a,
this knife being rendered vertically adjustable by the screws i.
The knives d, g, form the blades of a pair of shears, which act in unison to cut
or sever the shank-pieces from the plate or blank as hereinafter described, the edge
of the knife d being curved as shewn in Figure 1 to give them a "shear cut."
Disposed on the bed-piece a immediately beneath the knife d is a bed die j,
which is secured in position by the set screws K, as best seen in Figure 2.
The upper face of this die conforms obversely with the lower face of the knife d,
which constitutes the movable die of the machine and performs the double function
of a die and knife.
In the use of my improvements, power is applied to turn the shaft m, and, as the
cross-head c descends, the plate or blank s is fed into the machine until flush with
the inner face of the bed-knife g.
The cross-head continuing to descend, the punches fare next brought into action
and punch the requisite lioles in the first shank-piece on the plate, after which the
cross-head is raised carrying with it the knife d and punches f, and the plate is
pushed or fed forward until brought into contact with an adjustable stop t attached
to the bed-piece a.
The motion of the knife d is now reversed by the revolution of the shaft m, and
the cross-head c again descends, causing the punches f to punch the plate s for the
next succeeding shank-piece, and the shank-piece originally punched to be cut from
the strip or plate by the knives d, "g and dropped onto the bed-die j, where
it will be bent or pressed into the proper form by the descending knife or
movable die d in a manner which will be readily obvious without a more explicit
description.
It will be understood that the shape of the lower face of the knife d and the
upper face of the die jare such as to give to the shank-pieces cut from the strip s
the requisite form.
It will also be understood that all of the leading parts of the machine are made
adjustable where adjustability is necessary by suitable appliances therefor,
The holes for receiving the punches fare formed in the bed-knife g, said knife
acting in the dual capacity of a knife and bed-die for said punches.
C
I do not, however, confine myself to using the lower knife as a bed-die for the
punches, as another die for that purpose may be employed, if desired.
The bed-piece a is constructed with, suitable openings to receive the knife
die j, and stop t with their attaching and adjusting screws, as well as other parts of
the machine which require to project into or through the same.
± A suitable stripper (not shown) is employed for stripping the plate from
the punches; and there are also spring push-pins and other suitable means
employed for removing the finished shank-piece from the die j, which are not
shown, as I do not confine myself to any special means for the last named
purposes.
The blank or plate s, from which the shank-pieces are cút, may be a short
strip, or in the shape of a long ribbon, as most convenient, and it may be fed to the
knives by hand or by suitable machinery, gnides being provided to direct it properly
to the punching, cutting and stamping devices described.
Neither do I confine myself to using the punch exclusively for manufacturing
the shank-pieces of boots and shoes, as it is well adapted for other purposes.

page_text: 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 I claim
in a combined punching, cutting and stamping machine
First. The combination of a punch or punches adapted to form a hole or holes in
a strip or sheet of metal or other material as it is fed into the machine, a stationary
knife and a movable knife adapted to act in conjunction to cut or shear a piece
from the said strip or sheet; a bed-die and a movable die adapted to act in
conjunction to stamp or form the piece cut from said strip or sheet, and operative
mechanism, said movable knife constituting also the movable die, or being integral
therewith, substantially as described.
Second. The combination of a punch or punches adapted to form a hole or holes,
in a strip or sheet of metal or other material as it is fed into the machine, a
stationary knife and a movable knife adapted to act in conjunction to cut or shear
a piece from said strip or sheet, a bed-die and a movable die adapted to act in
conjunction to stamp or form the piece cut from said strip or sheet, a stop for
regulating the feed of said strip or sheet, and operating mechanism, said movable
knife constituting also the movable die or being integral therewith, substantially as
set forth.
Third. The combination of a bed-die, a movable die, a bed-knife, a movable
knife, a punch or punches, a stop for the strip or sheet, and operative mechanism,
the bed-knife constituting also the bed-die for the punch or punches, or being
integral therewith, substantially as described.
Fourth. The knives d, g, punch f, die j, stop t, cross-head c, pitman n, shaft m,
-bed a, and standards b, combined and arranged to operate substantially as set forth.
Fifth. The cross-head c, carrying a movable punch, knife and die, in combination
with a corresponding bed-knife and dies, a stop for the strip or sheet, and operating
mechanism, substantially as, and for the purpose, specified.
