PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Shovels and Spades, and in'
the Tools used therefor.
I, HENRY ROBERT ANDERSON of Harvest Lane, Sheffield, in the County of
York, Shovel Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of spades and shovels having open
back sockets and more particularly to the method of and the tools for turning such
sockets, that is forming them into a tubular shape to receive the handle.
I propose that this turning operation shall be done at the same time that the
spade or shovel is stamped to form but it may be made a separate operation if
preferred.
I make the tool in the form of a pair of depending jaws of the length or there-
abouts of a shovel socket and hinged or pivotted together.
They are curved inside so that when closed there is a hole through them
approximating to size and length of the socket they are intended to close. A
weighted lever projects from the side of each jaw their tendency being to close the
jaws but they are kept apart or open by one or more elastic spiral springs. The
tool is carried on the underside of the tup or ram of a steam hammer or other
stamper.
A cylindrical mandril of the size of the inside of the socket is suitably held and
supported in position underneath the closing tool, and the part of the shovel plate
to form the socket is laid thereon.
When the closing tool descends and strikes the plate, the concave shape of the
jaws above and the mandril below press the plate into a semicircular form, and the
impetus and momentum given to the weighted levers cause them to close the jaws
and press the plate round the mandril thus forming a complete socket.
The rebound and the reaction of the expanded spring again raise the levers and
open the jaws for the next stroke. The mandril may be conveniently made loose
so that it can be drawn from the socket and again placed in position.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Shovels and Spades, and in
the Tools used therefor.
I, HENRY ROBERT ANDERSON of Harvest Lane, Sheffield in the County of
York, Shovel Maker, 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 the manufacture of spades and shovels having open
back sockets and more particularly to the method of and the tools for turning such
sockets, that is forming them into a tubular shape to receive the handle.
I propose that this turning operation shall be done at the same time that the
spade or shovel is stamped to form, but it may be made a separate operation if
preferred.

page_text: The annexed sheet of drawings illustrates my invention as applied to a steam
¡hammer.
Fig. 1, is a top view of the closing tool or cramp, as fixed to front of tup or die.
Fig. 2, front view of same tool, closing upon the socket of shovel or spade.
I make the tool in the form of a pair of depending jaws A and B, of the length
or thereabouts of a shovel socket and hinged or pirotted together at C, they are
curved inside. so that when closed there is a hole through them approximating to
form size and length of the socket they are intended to close. A lever or arm D
and D2, projects from the side of each jaw A, and B, their tendency by gravitation
being to close the jaws, but they are. kept apart or open by one or more elastic
spiral springs E, or by equivalent means. The tool so constructed is carried on
the front of the tup or die F, of a steam hammer or of any other stamper.
A cylindrical mandril G, of the size of the inside of the required socket is
suitably held and supported in position underneath the closing tool, and the part of
the shovel plate to form the socket rests thereon. When the closing tool descends
and strikes the plate, the, concave shape of the jaws above and the cylindrical
mandril below press the plate into a semicircular form, and the impetus and
'momentum given to the levers D and D', causes them to close the jaws and press
the socket plate round the mandril G, thus forming a completed socket.
I find however in practice that it is better not to rely upon the unaided force of
the levers D and D2, as above described, but to give certainty to their action by
pressing upon them by the hands or by other means.
The reaction of the expanded spring E, again raises the levers and opens the
jaws A and B, for the next stroke.
The mandril G, may be conveniently made loose so that it can be drawn from
the socket and again placed in positiou.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved method of turning the sockets of spades and shovels by means
of a pair of jaws pivotted together, which clasp and bend the socket-plate round a
mandril or stake, substantially as hereinbefore described.
2. A closing tool for bending and forming the sockets of spades and shovels,
consisting of a pair of hinged or pivotted jaws A and B, retained in an open position
by means of a spring E, or other equivalent means, substantially as hereinbefore
described and illustrated.
3. As a means for bending and forming the sockets of spades and shovels, a
closing tool having two jaws A and B, working together upon a centre or axis, and
having a hollow recess corresponding with the form of the socket; provided with a
spring E, or equivalent means for holding the jaws apart until required to operate;
in combination with a mandril G, upon which the socket plate rests and round
which it is bent by the closing of the said jaws, substantially as herein before
described and shown in the drawings.
