PROVISIONAL SPECIFICATION,
Improvements in and relating to Presses for Forming and Olosing
the Sockets of Shovels and Spades.
We, JOHN HODKINSON and PETER HODKINSON, trading as Hodkinson Brothers,
and both of 150, Hardybutts, Wigan, Shovel Manufacturers, do hereby declare
the nature of our said invention to be as follows:-
The object of this invention is to form and shape the sockets of shovels and
spades at one operation, in lieu of two or three operations as heretofore, and
our invention consists of a press, having a divided matrix or bed block, the parts
of which approach each other under the impulses of a set of rams operated by
steam or other Huid pressure. The press also comprises a forging or pressing
tool or drop hammer, with a semi-circular cavity, corresponding with a like
cavity in the divided block, and when brought down upon such divided block
completing the shape of socket required.
The material to be brought into shape is placed upon a mandril immediately
above the divided block. Steam or other fluid is then admitted behind the rams,
and the pressing tool being lowered the three forces immediately bring the
socket to the shape required.
The steam or other fluid admitted to the rams is controlled by a slide valvo
operated, preferably, by the foot, which, when the operator's foot is removed, is
designed with the aid of a spring or balance weight to shut off the steam to the
rams and open an exhaust outlet, but when the foot is placed on the valve, to
admit the steam to the rams and close the exhaust.
As a modification one half only of the divided block may be moveable. Tho
return strokes of the rams may be effected by the exhaust, or by springs or
balance weights. The means for supporting and guiding the blocks may vary
with requirements, as also the shape of such blocks and the pressing tool.

Improvements in and relating to Presses for Forming
the Sockets of Shovels and Spades.
We, JOHN HODKINSON and PETER HODKINSON, trading as Hodkinson Brothers,
and both of 150, Hardybutts, Wigan, Shovel Manufacturers, do hereby declare

page_text: 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 object of this invention is to form and shape the sockets of shovels and
spades at one operation, in lieu of two or three operations as heretofore, and
our invention consists of a press having a divided matrix or bed blook the parts
of which approach each other under the impulses of a set of rams operated by
steam or other fluid pressure. The press also comprises the forging or pressing
tool or drop hammer with a semi-circular cavity corresponding with a like
cavity in the divided block and when brought down upon such divided block
completing the shape of socket required.
The material to be brought into shape is placed upon a mandril immediately
above the divided block. Steam or other fluid is then admitted behind the rams,
and the pressing tool being lowered the three forces immediately bring the
socket to the shape required.
The steam or other fluid admitted to the rams is controlled by a slide valve,
operated preferably by the foot which when the operator's foot is removed is
designed with the aid of a spring or balance weight to shut off the steam to the
rams and opens an exhaust outlet, but when the foot is placed on the valve to
admit the steam to the rams and close the exhaust.
As a modification one half only of the divided block may be moveable. The
return strokes of the rams may be effected by the exhaust or by springs or
balance weights. The means for supporting and guiding the blocks may vary
with requirements, as also the shape of such block and the pressing tool.
On the accompanying drawing
Fig. 1 illustrates a side elevation (partly in section) of a press and its
appurtenances according to our invention.
Fig. 2 is a vertical section of a detail.
Fig. 3 illustrates a socket formed by our invention.
(A) is a suitable bed upon which is mounted the two half portions (B) (B*) of
the divided matrix.
In guides (C) and suitably balanced we mount the hammer and pressing
tool (D), in which is formed a semi-circular cavity (E), corresponding with a
like cavity (F) in the two half portions (B) (B*) of the matrix.
Each of the said portions (B) (B*) is connected to a ram or piston (G) work-
ing within cylinders (H) under the action of steam, or other fluid under pressure,
supplied by pipes (I) and (J).
(k) is a foot valve for controlling the admission of steam to the cylinders (H),
and comprises a piston (L) with two ports (shewn dotted see Fig. 2) which
respectively come in line with the outlet passage of the valve upon the piston
being depressed, or released, and when the lower port comes in line it opens to the
atmosphere and allows the cylinders (II) to exhaust. When the upper port comes
in line it admits the live steam to the cylinders. The piston (L) is depressed by
the aid of foot plate (N), and raised by spring (M).
The material of which the socket is to be formed is first placed upon a mandril
above the divided matrix and the pressing tool (D) brought down to give it the
approximate shape of the intended socket. It is then allowed to lie within the
recess of the blocks (B) and (B), and by a further lowering of the press the
final shape (or closing) of the socket is effected.
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 5
we claim is:-
1-In means for forming and closing the sockets of shovels and spades, a
press having a divided matrix the parts of which approach each other under the
impulses of a set of rams operated by steam or other fluid pressure, in combina-

page_text: with a ram or pressing tool formed with a cavity and adapted to press upon the
object between or upon the divided matrix, as set forth.
2: In means for forming and closing the sockets of shovels and spades, the
arrangement and combination of parts substantially as herein set forth.
Dated this 14th day of August 1900.
