PROVISIONAL SPECIFICATION.
Improvements in Metallic Sockets for Picks.
I, GEORGE SPENCER WATERFALL, of Albion Works, Pea Croft, in the City of
Sheffield, Manufacturer, do hereby declare the nature of my invention to be as
follows:-
My invention has for its object to permit the shafts of picks to be readily forced
into the sockets upon which the pick head or blades fit, but also to prevent its
withdrawal when forced into position.
To accomplish this I propose to make the socket out of a plate of metal, and
preferably of steel, formed to a desired shape and then bent round into the
finished shape, the two edges being brought together but preferably not secured.
Before the plate so cut out to shape is bent, I form upon its upper portion a
number of teeth similar to those of a rasp, inclining upwards, and preferably in
rows or series.
They may be short or long teeth, and of any size, or configuration, and number.
They will permit a wood shaft to be forced past them but not to return.

Improvements in Metallic Sockets for Ficks.
I, GEORGE SPENCER WATERFALL of Albion Works, Pea Croft, in the City of
Sheffield, Manufacturer do hereby declare the nature of this invention and in what
manner the same has to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention has for its object to construct a metallic socket for picks, such as
those in use by miners and others, in such a manner that the wood shaft can be
readily forced into position, but that its withdrawal will be prevented, and that
without the use of cross-pins or the like.
In carrying out my invention I construct the inside of the upper part of the
socket with a series of projecting teeth.inclining upwards and which by reason of
such inclination will permit the passage of the shaft to position, but will obstruct
its withdrawal.
The annexed drawings illustrate a socket made according to my invention.
Fig. 1, represents the end view, and
Fig. 2, a side view of a socket.
Fig. 3, section of same through A, B.
C, is the socket, and the inwardly projecting teeth are marked D.
prefer to make the socket from plate steel punched out to the desired shape
or configuration and afterwards to bend it round to the finished form of a socket
as shown in Fig. 2.

page_text: While the cut out plate is flat I produce upon its upper part a series of teeth,
somewhat similar to the coarse teeth of a rasp, and arranged in lines or otherwise,
the front or edges of the teeth being at the top.
I may however produce my improved socket by casting it in run-steel or other
like metal instead of wrought steel, and the teeth D, may be of any suitable size
or configuration which will permit the wood handle to be forced past them in the
manner described. In all cases the socket is split or divided down one side
vertically.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, 1 declare that what
I claim is :-
1. The improved metallic socket for picks as hereinbefore described and shown.
2. A metallic socket for pick handles provided with a series of internally and
upwardly projecting teeth, for the purpose specified, and as hereinbefore described
and shown.
