We, LOUIS WACHE, and ROBERT JAMES, of the Trafalgar Engineering Works,
Trafalgar Street, Sheffield, in the County of York, Engineers and Tool Makers, do
hereby declare the nature of our said Invention, to be as follows:-
This Invention relates to an improved method and means of cutting out,
stamping or punching shovel plates, spades, and similar articles, hereinafter
intended to be comprehended where the word "spades" alone occurs.
As at present manufactured, such articles are cut out, stamped or punched from
a steel, iron or other suitable metal blank or strip, of a suitable thickness, width
and length, in such a manner as that there is a very considerable waste of metal,
the blades of the spades being stamped out side by side and the whole of the
intervening metal between the shanks of these adjacent spades being waste.
An especial object of the present Invention is to prevent this waste, and
according to the present improvements we are enabled to cut out a considerably
greater number of spades from any given strip of metal, than is effected according
to the present system.
The said improved method consists in stamping out spades from a metal blank
or strip which is continually reversed in position at every stroke of the stamping
machine, in such a manner as that the adjacent spades are stamped out from the
said blank or strip in reverse positions, so that the metal between every two
alternate scoops or blades of the spades forms the shank of the intermediate spade,
and the metal between the shanks of every two alternate spades forms the scoop
or blade of the intermediate spade; and by this improved method of manufacture
the whole body of the metal blank or strip is utilized in the manufacture of the
spades, and the only waste consists of a small strip or strips at each end, and of the
small pieces which are subsequently cut from the ends of the blank.
In carrying the Invention into effect, we prefer to use apparatus substantially of
the construction hereinbefore described. Such apparatus is formed with top and
bottom sets of steel cutting blades, both sets of steel blades being partly secured in
fixed positions and partly adjustable so as to accommodate different widths and
sizes of spades, and the bottom set being carried by a fixed bed plate, and the
upper set being carried by a vertically reciprocating block attached to and actuated
by any suitable stamping machine.

page_text: The said top and bottom sets of knives are set opposite each other so as in
actuation to cause the desired severance of the interposed metal strips or blank at
their meeting edges.
The bed plate is formed so as to be capable of being adjusted and fixed in any
desired position to accommodate the particular formation of spade required to be
manufactured, and the cutting blade which stamps out the sides of the shank and
the top edges of the blade of the spades is securely bolted or fixed to an upraised
part of the bed plate. The cutting blade which stamps out the side edges of the
blade of the spade is adjustable so that it can be set to stamp out any desired
width of the blade, and this cutting blade is securely bolted or fixed to a
supplementary adjustable bed plate which is dovetailed into and can be securely
bolted or fixed in any desired position to the main bed plate, and can be also
rigidly kept in any such position by set screws acting in lugs or dogs rising from
the main bed plate.
The reciprocating block is also similarly adapted with a fixed cutting blade, and
with an adjustable cutting blade, and in operation both sets of such cutting blades
are arranged and rigidly set opposite each other, so as to properly punch out the
metal plate or blank placed between them, and this operation is, according to the
present improvements, carried out in such a manner as that each successive stroke
of the upper block with its cutting blades completes the formation of one spade
and partly forms the adjacent spade, and after each such stroke the position of
the said metal plate or blank is reversed so that the next stroke completes the
formation of the spade the formation of which was commenced by the said
preceding stroke, and to a similar extent commences the formation of the next
adjacent blade, and, as hereinbefore mentioned, 'this improved method is effected in
attaining the desired result, and in avoiding the usual excessive waste of metal.

We, LOUIS WACHE, and ROBERT JAMES, of the Trafalgar Engineering Works,
Trafalgar Street, Sheffield, in the County of York, Engineers and Tool Makers, do
hereby declare the nature of our said 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 an improved method, and to improved means to be
employed in carrying out such method, of cutting out, stamping or punching
(hereinafter referred to under the general term "cutting out") shovel plates, spades,
and similar articles (hereinafter referred to and comprehended under the general
term "shovels") from a steel, iron, or other metal blank, hereinafter referred to
under the general term metal blank."
On the accompanying drawings; Fig. 1, represents the present method of cutting
out shovels from a metal blank :-Fig. 2, represents our improved method of cutting
out the shovels:-Figs. 3, to 5, represent the improved means hereinafter described
for carrying such improved method into effect; Fig. 3, representing a plan view of
a top set of cutting blades; Fig. 4, a plan view of a bottom set of cutting blades;
and Fig. 5, an elevation of the apparatus in position for operation.
As at present manufactured such articles are cut out, stamped or punched from
a steel, iron, or other suitable metal blank or strip of a suitable thickness, width
and length, in such a manner as that there is a very considerable waste of metal,
the blades, 1, of the shovels being cut out side by side, as illustrated in Fig. 1, and
the whole of the intervening metal, 2, between the shanks, 3, of the adjacent
shovels being waste.
An especial object of the present Invention is to prevent this waste, and
according to the present improvements we are enabled to cut out a greater number
of shovels from any given strip of metal than is effected according to the present
system.
The said improved method is illustrated in Fig. 2, and consists in cutting out
shovels from a metal blank, or from metal blanks, which is or are reversed in
position at every stroke of the stamping machine, in such a manner as that the
adjacent shovels are cut out from the said blank or blanks in reverse positions, as
illustrated in such Figure, the ☐ line, A, indicating the first cut; the
line, B, the
second cut which occupies the same position as the line, A, while being cut;
the ☐ line, C, the third cut, and so on; so that the metal between every two
alternate scoops or blades, 1, of the shovels forms the shank, 3, of the intermediate
shovel, and the metal between the shanks of every two alternate shovels forms the
scoop or blade of the intermediate shovel, and by this improved method of
manufacture the whole body of the metal blank or strip is utilized in the
manufacture of the shovels, and the only waste consists of a small strip or strips, 2,
at each end, and of the small pieces, 2, which are subsequently cut from the ends
of the shanks, 3.

page_text: In carrying the Invention into effect, we prefer to use apparatus substantially of
the construction hereinafter described with reference to Figs. 3, to 5, of the drawings.
Such apparatus is formed with top and bottom sets of steel cutting blades, 4, 5,
both sets of such blades being in part secured in fixed positions, and in part
adjustable so as to accommodate different widths and sizes of shovels, and the
bottom set being carried by a fixed bed plate, 6, and the upper set being carried by
a vertically reciprocating block, 7, attached by a shank or shanks, 8, to and
actuated by any suitable stamping machine.
The said sets of cutting blades, 4, 5, are set opposite each other so as to just
clear each other in descending so as in actuation to cause the desired severance of
the interposed metal blank or blanks at the meeting edges of the said cutting
blades.
The bed plate, 6, is formed so as to be capable of being adjusted and fixed in
any desired position to accommodate the particular formation of shovel required
to be manufactured, the slots, 9, affording this provision. The cutting blades, 4,
of both sets are securely bolted or fixed to raised parts, 10, of the bed plate or
block as illustrated, and the cutting blades, 5, are securely bolted or fixed to
raised parts, 11, of supplementary adjustable bed plates, 12, which are dovetailed
into or can slide against and can be respectively securely bolted or fixed in any
desired position to the main bed plate, 6, or block, 7, by bolts, 13, and can be also
rigidly kept in any such position by set screws, 14, acting in lugs or dogs, 15,
rising from the bed plate or block, 6, 7, the slots, 16, in the bed plates, 12,
permitting of the adjustment thereof as desired.
The adjustable cutting blades afford facility of cutting out different sizes of
shovels in the same machine, and in operation both sets of the cutting blades, 4, 5,
are rigidly set and arranged opposite each other in the manner aforesaid so as to
properly cut out the metal blank or series of blanks placed between them, and this
operation is, according to the present improvements, carried out in such a manner
as hereinbefore referred to as that each successive stroke of the machine completes
the formation of one or of a number of superposed shovels and partly forms the
following adjacent shovel or shovels.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. The improved method of stamping out shovels from a metal blank or blanks
as hereinbefore described with reference to Fig. 2.
2. The combination of the bed plate, 6, adapted with the fixed cutting blade, 4,
with the bottom adjustable plate, 12, adapted with the cutting blade, 5, as herein
set forth.
3. The combination of the vertically reciprocating block, 7, adapted with the
fixed cutting blade, 4, with the top adjustable plate, 12, adapted with the cutting
plate, 5, as herein set forth.
4. The combination of the bed plate, 6, with the block, 7, each being adapted
with the said fixed and adjustable cutting blades, 4, 5, set in relation to each other
in such a manner as to cause the desired severance of the interposed metal blank
or blanks from which the shovels are to be cut at the meeting edges of the said
opposite sets of cutting blades, as herein set forth.
