An Improvement in Miners' and other Picks and Tools of a like
Kind having Detachable Working Parts.
WILLIAM SEEDHOUSE 52 Furnival Street, RICHARD NORBURY 52 Furnival
Street aforesaid Engineers and CHARLES EDWARD TRICKETT 64 South Grove
Road, Commercial Traveller all and each of Sheffield in the County of York,
do hereby declare the nature of this invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement :-
We cast in iron steel or other material an improved pick socket head, Fig. 1,
with an ordinary shaft eye through, to receive an ordinary miners pick shaft, and
the arms of the pick head are as usual cast hollow to receive loose or interchangable
working tools.
In this improvement there is a slot A. Fig. 1 and Fig. 5. left open through
each arm.
A cushion of rubber or leather or other suitable material is placed in the head of
each Bocket barrel, Fig. 2, and Fig. 5, a double key or peg, Fig. 3. having the

page_text: underneath of head finished round-is passed up the socket, the head of same
butting the cushion aforesaid; which key or peg may be held loosely in position
by a small stud or revit passed through the head of same B. Fig. 1. and Fig. 3-
The application of the improvement being that ordinary pick or tool points or
heads having the tang end rounded off Fig 4. to face, opposite, with the similar
finish on the underneath of key or peg, Fig. 3, may be fixed quickly, easily removed
& replaced as may be required the key or peg aforementioned releasing by pressure
through the slot A in the socket arms before refered to.
In making this application we wish it understood that we are aware that picks
having seperate working points have before now been used & to this feature we
make no claim.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. In a detachable pick or tool, the counteraction releasing principle contained,
whereby the tool may be released by friction, or pressure, between the rounded
surface of the tool;tang and the underneath of the wedge head respectively, as
described and illustrated.
2. In a detachable pick or tool socket barrel, the method of securing, within the
same, of the key or peg thereby allowing the latter sufficient play to release the
tool substantially as described & illustrated.
3. In a detachable pick or tool socket the double key or peg thereby adding
great strength to the socket barrel containing as it does the tang of the working
tool substantially as described and illustrated in the accompanying drawings.
Dated this Third day of April 1895.
