Improvements in or relating to Miners' Picks or the like.
:
I, WILLIAM KIRKLEY BIRKINSHAW, of Old Croft House, Quarndon, near
Derby, in the County of Derby, Merchant, do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to an implement which may be used in the repairing of
the movable points or tools of miners' picks and similar tools or as the pick
or head.
With the ordinary pick, where the points are made in a piece with the head,
being welded on to it, when it is required to heat, forge and temper the points so
as to resharpen them, the pick can be held by one end or point while the other is
placed in the fire, and manipulated, no tongs being requisite for this purpose;
where however short detachable points are employed, some means of holding the
points while they are being heated and worked must be found, as the point is
too short to allow of its being grasped when hot by the hand of the operator.
At present this is done by fitting a pair of smiths' tongs upon the shank end of the
point, but this involves some loss of time, and trouble, and to avoid the use of
tongs for this purpose is the object of the present invention.
In carrying out the invention I provide an implement which I may call a holder
provided at one or at each end with a socket of the proper shape and size to
receive the shank of the point so that when it is necessary to heat or forge the
point it is slipped into the socket and when finished can be instantly removed by
a touch with a hammer, or a shake or blow, and another point replaced while by
making the holder double-ended two points from a pick can be inserted simul-
taneously, and the whole treated in a similar manner to that now adopted with
the ordinary picks, in which the points form part of the whole head. I prefer
to set the sockets in a plane to one side of the axis of the tool holder so that
the back end of the point is accessible and it may be easily struck to remove the
point; I also prefer to make each socket split so that a certain amount of spring
may be obtained which while affording a more secure grip upon the point will
also allow of its being more easily driven out. The holder itself may be made
solid or hollow and of any suitable material, say iron or steel, or an iron body
with steel sockets may be employed; or the holder may be made out of a piece
of tube, in which case I still prefer to set the sockets out of line with the axis of
the holder, but in this case it will not be essential to do this as the point could be
kuocked out by inserting a rod up the tube, if the sockets were in the axial line
of the tube. By the use of this implement a considerable saving of time and
trouble is effected.
When making this implement to serve as the pick a socket may be provided
for the handle and the tool sockets would not be split.

Improvements in or relating
I, WILLIAM KIRKLEY BIRKINSHAW, of Old Croft House, Quarndon, near
Derby, in the County of Derby, Merchant, 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 an implement which may be used in the repairing of
the movable points or tools of miners' picks and similar tools or as the pick
or head.
With the ordinary pick, where the points are made in a piece with the head,
being welded on to it, when it is required to heat, forge and temper the points so
as to resharpen them, the pick can be held by one end or point while the other
is placed in the fire, and manipulated, no tongs being requisite for this
purpose; where however short detachable points are employed, some means of
holding the points while they are being heated and worked' must be found, as the
point is too short to allow of its being grasped when hot by the hand of the
operator. At present this is done by fitting a pair of smiths' tongs upon the shank
end of the point, but this involves some loss of tiine, and trouble, and to avoid the
use of tongs for this purpose is the object of the present invention.
In carrying out the invention as shown in the accompanying drawings, I provide
an implement A which I may call a holder provided at one end as shown in
Figure or at each end as shown in Figure 2 with a socket B of the proper shape
and size to receive the shank C' of the point C so that when it is necessary to
heat or forge the point C it is slipped into the socket B' and when finished can
be instantly removed by a touch with a hammer, or a shake or blow, and another
point replaced, while, by making the 'holder double-ended two points from a pick
can be inserted simultaneously as shown in Figure 2, and the whole treated in a
similar manner to that not adopted with the ordinary picks, in which the points
form part of the whole 'head. I prefer to set the sockets B in a plane to one side
of the axis of the tool holder A as shown so that the back end of the shank C¹ is
accessible and it may be easily struck to remove the point; l'also prefer to make
each socket B split as at B so that a certain amount of spring may be obtained
which, while affording a more secure grip upon the shank C, will also allow of
its being more easily driven out. The holder A may be made solid or hollow and
of any suitable material, say iron or steel, or an iron body with steel sockets may
be employed; or the holder A' may be made out of a piece of tube, in which
case I still prefer to set the sockets out of line with the axis of the holder, but in
this case it will not be essential to do this "as the point could be knocked
out by inserting a rod up the tube, if the sockets were in the axial line of the
tube. By the use of this implement a considerable saving of time and trouble
is effected.
'
When making this implement A B to serve as the pick a socket or eye may be
provided for the handle and the tool sockets B would not be split.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claiin is;-
1. In the forging of pick points the employment of an implement consisting of a
body or handle such as A and socket such as B adapted to receive the shank of
the pick point substantially as and for the purpose described.
2. An implement such as A provided with a split socket such as B B at one or
each end substantially as and for the purpose described and illustrated in the
accompanying drawings.

page_text: 3. An implement formed of tube and adapted to receive a pick-point such
as C C in one or each end substantially as and for the purpose described.
4. The combination with an implement such as claimed in Claim 1 of a handle-
receiving socket or eye substantially as and for the purpose described.
5. The complete pick-point holder substantially as described and illustrated in
Figure 1 or Figure 2 of the accompanying drawings.
