We, MALCOLM DITCHBURN, of Flimly Brow, near Maryport, and
WHITEHEAD, of Seaton, near Workington, Cumberland, Gentlemen, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in pickaxes the object being by the
arrangement and construction of the socket to greatly strengthen this part,
while the head or pick when it has worked slack can be readily tightened and
fitted as firmly as when new.
In carrying our invention into practical effect the socket is made detachable
from the pick and is of a convenient size and shape to receive the end of the
handle, while upon each side of the said socket a dovetail or wedge shaped
projection is formed designed to take into correspondingly shaped recesses formed
upon each side of the hole or perforation through which the aforesaid detachable
socket passes, and by this means the socket with handle is firmly secured to the
pick, while the said socket may be split for a sufficient distance at one side to
expand slightly under the force of a wedge driven into the extremity of the
handle for securing it within the socket.

We, MALCOLM DITCHBURN, of Flimly Brow, near Maryport, and
WHITEHEAD, of Seaton, near Workington, Cumberland, Gentlemen, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in pickaxes, the object being, by the
arrangement and construction of the socket, to greatly strengthen this part,
while the head or pick, when it has worked loose, can be readily tightened and
fitted as firmly as new.
In carrying our invention into practical effect, the socket is made detachable
from the pick and is of a convenient size and shape to receive the end of the

page_text: handle, while upon each side of the said socket, a dovetail or wedge shaped
projecting rib is formed, designed to take into a correspondingly shaped recess
formed upon each side of the hole or perforation in the head or pick through
which the aforesaid detachable socket passes, and by this means the socket with
handle, is firmly secured to the head or pick. The socket may be split for a
sufficient distance at one or both sides so as to allow of it expanding or being
contracted for the purpose of tightly gripping the shaft or handle, while within
the socket and near the upper end, a small flange or rib may be formed, pro-
jecting a sufficient distance, and designed to "bite or grip the shaft.
In order that our invention may be more fully understood, we will now proceed
to describe same with reference to the accompanying drawings in which:
Fig. 1 is a side elevation of the pick, socket and a portion of the handle
constructed according to this invention.
Fig. 2 is a plan of a part of the pick or head showing the hole or perforation
through same.
Fig. 3 is a plan of the socket.
Fig. 4 is a front elevation of the said socket, and
Fig. 5 a side view of same.
As shown in the drawings the socket a, which is of a convenient shape to
receive the end of the shaft or handle c, is made detachable from the head or
pick b, while upon each side of the said socket, a dovetail or wedge shaped
projecting rib d is formed, designed to take into a correspondingly shaped
recess formed upon each side of the hole or perforation g in the head or pick b,
through which the aforesaid detachable socket a passes, and by this means the
socket with handle is firmly secured to the head or pick.
The socket may be furnished upon one or both sides with a slot h of sufficient
length, terminating in a circular opening m so as to render the extremity of the
socket sufficiently flexible for expanding or contracting slightly as required for
the purpose of tightly gripping the shaft or handle, while a small internal rib
or flanger is formed within the socket, designed to "bite" or grip the shaft as
aforesaid.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1/. The improvements in pickaxes, comprising the combination with a detach-
able socket such as a, furnished upon each side with a dovetail or wedge shaped
projecting part such as d, of the pick or head & furnished with a hole or perfora-
tion through which the socket a passes, the said hole or perforation being
provided at each side with correspondingly shaped recesses f into which the pro-
jecting ribs are designed to enter, the whole combined and arranged, sub-
stantially as herein described and shown with reference to the accompanying
drawings, and for the purposes specified.
2/. The combination with a pick or head such as b, of a detachable socket such
as a, furnished with projecting ribs such as 7, slotted at its upper extremity for
a sufficient distance as at and provided with an internal rib or flange such as r,
substantially as herein described and shown with reference to the accompanying
drawings, and for the purposes specified.
