New or Improved Machinery or Apparatus for Stamping or Forming
Metal Waists for Boots and Shoes.
We JOHN WARD JONES of 1 Canonbury Terrace, London, Engineer and EDWARD
KYNASTON BRIDGER of Temple Chambers Falcon Court Fleet Street London Gentleman
do hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention relates to machinery or apparatus for stamping up or forming into
the desired shape the metal waists of boots and shoes.
Now owing to their peculiar curves and forms there are many difficulties in forming
metal waists for boots and shoes by machinery and our present invention consists in
the arrangement and construction of dies and apparatus for making these metal waists
in the shape and form desired.
And in order that our present invention may be easily understood and readily
carried into practice we will proceed to fully describe same with reference to the
accompanying drawings.
The metal waists which our machinery is designed to produce are formed with each
side thereof turned downwards and under so that such turned under edge on each
side will embrace the outer edges of a metal plate on the boot or shoe. We form this
curved turned under edge in two operations, viz. :-firstly by turning over-" drawing"
down--the two edges of a flat piece of steel or tin plate (or other suitable sheet
metal) to about a right angle with the body of the plate and then secondly each edge
is separately turned under and inwards so as to leave a space between such turned in
edge and the body of the waist itself.
Figures 1 to 4 show the apparatus for the first nained operation and Figures 5 to 10
the apparatus for the second named operation. Figures 11 to 14 show a metal waist
of the particular form and shape produced by the dies of the form and shapes shown
in the other Figures of the drawings.

named operation.
Figure 2 is a plan of Figure 1.
Figure 3 is a vertical section on line 1-1 of Figure 2.
Figure 4 is a plan of the male die-the female die being removed.

operation.

part of Figure 5.

Figure 5.
Figure 8 is an underside plan of Figure 7-that is a plan of Figure 7 inverted.
Figure 9 is a vertical cross section of Figure 5 on line 2-2.
Figure 10 is a plan of Figure 6-that is a plan of the lower part or bottom die.
Figure 11 is a plan of the metal sheet after the first operation and Figure 12 a
cross section thereof.
Figure 13 is a plan and Figure 14 is a cross section of the metal sheet after under-
going the second operations, that is, Figures 13 and 14 are respectively a plan
and section of a finished metal waist for a gentleman's boot or shoe.
a is the platform or support mounted in the standards a¹ a¹ (or in any other
suitable manner) and on this platform a is secured the mail die b of the shape-on

page_text: This peculiar shaped male die 6 has a sliding rim or ring of metal 61 surrounding
it and normally kept pressed up to the top edge of the male die by the guide pins b
which travel freely through holes provided for them in the platform a and the
lower end of these pins 62 are normally kept pressed up by the spring b* (or by any
other suitable means) and intermediate plate or buffer thus leaving the said
slide 6¹ free to be forced down the sides of the male die when required, the spring b³
forcing back the rim 6' when the pressure from above
removed.
66 are two headed screw pins which serve to prevent the metal rim 6' from
coming off the die b.
The female die c corresponds in shape and fits over the male die b upon which it
is forced down by any suitable press or pressure, the separate central part being
normally held in the position shown in Figure 3 by a strong spring c but when the
female die c is pressed down over the male die 6 the part c¹ is forced back up the
hollow part of the die c-until such pressure is released whereupon the central
part c is forced down by the spring back to its normal position as in Figure 3.
The operation is as follows:-
:-
"
The piece of flat steel or tin plate (or other suitable.sheet metal plate) of the
desired size is placed in between the dies b and c (Figure 3) and then the dies are
forced together thus "drawing or forcing the two side edges of the piece of plate
down the sides of the male die b against which they lie closely then as the die c is
withdrawn from 6 the metal rim follows close up after it and catching the turned
down ("drawn" down) edge of the piece of metal plate forces same off the male
die ready to be removed such metal plate then having the shape or appearance
presented by Figures 11 and 12.
The top surface of the male die is made to any curve form or arch desired to
be given to the body of the metal waist and the underside of c is made to
correspond; also the die 6 is made in different sizes as to width and length and of
various forms as to the curves of its side 6x according to the size and shape desired
to be given to the various characters of metal waists-the female die c being formed
to correspond with and fit over the male die b whatever the latter's size and shape
may be.
We will now refer to Figures 5 to 14 and to the second operation.
d is the stand or platform having the upright support thereon. To the upper
part of d¹ is secured by the bolts d² (or in any other suitable manner) the block or
die e which is curved or formed along its top edge e¹ (see Figure 5) according to
the curve or form required to be given to the side of the waist and also curved or
formed on its inner face e (see Figure 10)-or not according to the curve form or
arch to be given to the body of the metal waist.
The upper part of Figure 7 is forced down or actuated by any suitable press or
pressure and has secured to it the block or die g by bolts for other suitable
fastenings.
This block or die g is curved or formed on its bottom edge g¹ to correspond with
the curve or form e¹ of the lower die e and also the dio g is curved or formed on its
face to correspond with the curve or form on the lower die e-thus the curve or
form of e¹ is approximately concave that of g¹ being convex while the curve or
form e is approximately convex and that of g³ concave.
The second operation is as follows:-
One edge of the partly formed metal waist as in Figures 11 and 12 is placed over
the lower die or block e said edge pointing towards the support d' as indicated in
Figure 5 and the top die g is then pressed down and so turns over ("draws"
down) the projecting edge of the metal waist until it lies close against the inside
face of the lower die e-the upper die is then withdrawn and the metal waist
removed from the machine and the edge on the opposite side of the waist is then
turned under in the same manner on a similar machine the only difference being in
the curves or forms of the dies e and g and which would be of the shape or form
which it is desired to impart to the said opposite side.
It will be obvious that the forms or curves of the dies or blocks e and g may be

page_text: varied to any extent according to the sizes and shapes desired to be imparted to the
finished metal waist.
We would remark that we make no claim herein to the metal waist per se nor do
we wish to limit ourselves to or to claim any method of actuating the aforesaid dies
or presses for forming such metal waists.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A machine or apparatus for the production of metal waists for boots and
shoes having a male die such as 6 with its two sides 6x 6x and its top surface
curved or shaped to form the curve or shape required to be given to the metal waist
and this die 6 acting in conjunction with a female die such as c the latter corre-
sponding in shape with the male die band having the movable spring centre piece c¹
therein substantially as and for the purposes hereinbefore described and illustrated
in Figures 1 to 4 of the drawings hereunto annexed.
2. The apparatus claimed in claim No. 1. in combination and acting in conjunction
with the parts 61 62 63 and 6 for removing the metal sheet from the male die b after
the two edges of the metal sheet have been turned down substantially in the
manner hereinbefore described and illustrated in Figures 1 to 4 of the drawings
annexed.
3. A machine or apparatus for the production of metal waists for boots and shoes
having a die such as e curved or shaped both on its top edge e¹ and side face e
according to the curve or shape required to be given to the finished metal waist such
which latter is
die e acting in combination and in conjunction with a die such as
curved or shaped on its lower edge g and side face g³ to correspond with the curve
or shape ele on the former substantially as and for the purposes herein before
described and illustrated in the drawings hereunto annexed.
