PROVISIONAL SPECIFICATION.
Improvements in Miners' and other Picks.
I, CHRISTOPHER HODKINSON, of 4 Warrington Road, Ince, near Wigan,.
Spade Maker, do hereby declare the nature of my said invention to be as
follows:-
My invention relates to miners' picks and consists of a divided steel socket and a.
metal clasp or bracing piece for securing the two edges of the socket together and
so prevent them opening apart when driven onto the wooden shaft or handle of.
the pick.
The metal clasp or bracing piece consists of a strip of steel about half an inch in
width with its two ends turned up. This strip fits inside the socket across the two.
adjoining edges and the two turned up ends of the strip take loosely in to slots.
formed near the two edges of the socket.
On the socket being driven on to the wooden handle such handle firmly holds the.
strip in position with its two ends in the slots and thus any tendency of the two.
edges of the socket to separate is prevented by the clasp holding them together.
In some cases one of the ends of the clasps may be rivetted in position in the
socket previous to the socket being placed upon the handle.
Dated this 8th day of August 1892.

COMPLETE SPECIFICATION.
Improvements in Miners' and other Picks.
1, CHRISTOPHER HODKINSON of 4 Warrington Road, Ince, near Wigan, Spade.
Maker, do hereby declare the nature of my said invention and in what manner the-
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention relates principally to miners' picks and consists of a divided steel.
socket and a metal clasp or bracing piece for securing the two edges of the socket
together and so prevent them opening apart when fitted onto the wooden shaft.
or handle of the pick.
In order that my invention shall be clearly understood I have hereunto annexed
a drawing thereof and will now describe the same with the assistance of the various-
figures and letters of reference marked thereon.
Fig. 1 is a full sized view of the socket of a miners' pick divided at A as.
illustrated, and
Fig. 2 a sectional plan view on line A-B.
This socket is fitted onto the wooden shaft or handle in the usual manner the
shaft being slipped into the socket and drawn through until the socket engages with
the tapered end of the shaft, and in order to prevent the divided portion of the
socket separating under the pressure of fixing it on to the tapered end of the shaft
slots or openings B. B. are formed in the two edges of said portion and a clasp or-
bracing piece C (seen separately in Figs. 3 and 4) is employed.
This bracing piece consists of a (by preference) flat strip of steel about half an
inch in width and three quarters of an inch in length with its two ends turned up as.
illustrated. Said strip fits inside the socket across the opening A (see Fig. 2) and
the two turned up ends D. D enter the openings B. B.
When the socket is fitted.

page_text: on to the shaft it will be seen that the clasp keeps the divided portion together and
prevents the same from separating and becoming broken.
The bracing piece C is curved to correspond with the outside curvature of the
shaft or handle or the inside curvature of the socket as illustrated more clearly in
Figs. 2 and 3. The ends D, D, by preference, lie flush with the outer surface of
the socket to receive the pick Ẻ (see Fig. 6) and they fit loosely into the
openings B, B to allow for a little play.
It will be observed that when the socket is fitted onto the handle the handle
serves to hold the bracing piece C firmly in its place with the turned up
extremities D, D in the openings B. B.
In some cases one end of the bracing piece C may be rivetted in the opening
previous to the socket being placed on the shaft or handle.
Two or more clasps or bracing pieces may be used if desired, a corresponding
number of slots B, B being formed in the socket.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1st. A clasp or bracing piece C (or a series of clasps) in combination with slots
or openings B, B, formed in the divided socket of a miner's pick or the like sub-
stantially as and for the purpose hereinbefore described and illustrated on the
accompanying drawing.
