PROVISIONAL SPECIFICATION.
An Improved Tool for use in Mines and Collieries.
GEORGE FARK, 16 Victoria Street, Kidsgrove, Certificated Mine and Colliery
Manager, and JOSEPH HANCOCK Mow Cop Chartermaster, both in the County of
Staffordshire, do hereby declare the nature of this invention to be as follows:-
Our invention has reference to a class of tools which are used in mines and collieries
and may be thus described.
We form by forging or other convenient method or methods from wrought iron,
wrought or cast steel an improved mining tool of any suitable size, one end of which is
shaped similar to an axe, the other end somewhat in the form of a hammer head, between
the edge of the axe and the face of the hammer head we form an aperture or slot of
suitable size and shape into which a handle or shaft of any suitable material, shape
and size is fitted for the purpose of being able to use the same. From experiments
we have carried out we find that a tool made according to our invention ten inches
long over all, that is from the edge of the axe to the face of the hammer head, the
blade of the axe would be about five inches wide and of a proportional tapering
thickness from its head to the edge of the blade, the opposite or. elongated hammer
end would be three inches from the face of the hammer to the head, larger or smaller
tools being somewhat similarly proportioned, in fact this hammer head is somewhat
similar in shape to the head of a sledge hammer and preferably of an octagonal cross
section, although the said head may be round, oval, square or other convenient shape
in cross section. It is well known by those employed at or in mines, collieries and
similar places that the tools at present in use are bulky, and as a rule only one
operation can be performed with each tool, that is to say if a workman is in one part
of a mine and wants a hammer, having only an axe with him he cannot conveniently
use that tool as a hammer, but our improved tool can be used, one end as an axe for
cutting timber, and as a wedge for cleaving or splitting timber, coal &c. the opposite
or sledge hammer end for plate laying, timber setting and other mining purposes thus
it will be seen by our invention we are enabled to form a tool with which several
operations can be performed, instead of employing a separate tool for each operation
required to be done.

GEORGE FARR, 16 Victoria Street, Kidsgrove, Certificated Mine and Colliery
Manager, and JOSEPH HANCOCK, Mow Cop Chartermaster, both in the County of
Staffordshire, 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 :-
Our invention has reference to a tool or class of tools which are used in mines and
collieries, and may be described as follows.
We form by forging, casting or other convenient method or methods from wrought
iron, wrought or cast steel an improved mining tool of any suitable size, one end of
which is shaped similar to an axe, the opposite end being shaped somewhat in the
form of a hammer head, about midway between the cutting edge of the axe shaped
portion and the face of the hammer head, we form an aperture or slot of any suitable

page_text: size and shape through the whole depth of the central portion of the tool, into which
aperture a handle or shaft of any suitable materia!, shape and size is fitted for the
purpose of being able to use the said tool. From experiments we have carried out,
we find that a tool, when made according to our invention, ten inches long over all,
that is from the cutting edge of the axe to the face of the hammer head, the blade of
the axe would be about five inches wide at the widest part, and of a proportional
tapering thickness from the central part of the said tool to the cutting edge of the axe,
and the opposite or elongated hammer head end would be about five inches and a half
from the face of the hammer head to the centre of the head of the tool, larger or
smaller tools being somewhat similarly proportioned, in fact the hammer head of this
improved tool is somewhat similar in shape to the head of a sledge hammer and
preferably having an octagonal cross section, although the said hammer head may be
round, oval, square or other convenient shape in cross section. It is well known by
those people employed at or in mines, collieries and similar places that the tools at
present in use are bulky, and as a rule only one operation can be performed with each
tool, that is to say if a workman is in one part of a mine having only an axe with him,
he cannot conveniently use that axe as a hammer, but our improved tool can be used,
one end as an axe for cutting timber, and as a wedge for cleaving or splitting timber,
coal &c., the opposite or sledge hammer end for plate laying, timber setting and other
mining purposes, thus it will be understood that we are enabled to form a tool, with
which several operations can be performed, instead of having to employ or use a
separate tool for each operation required to be done.
In order that our invention may be more readily understood and explained in
detail, we have hereunto annexed a sheet of drawings on which letters of reference are
marked on corresponding parts on all the Figs. alike.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation of an improved tool, made according to our invention, and
Fig. 2 is a plan view of Fig. 1.
In the drawings hereunto annexed, we have shewn one form of tool made
according to our invention, and drawn to a scale about one half of the full size.
In these Figs. a is the hammer head portion of the improved tool having an
octagonal cross section, and the axe shaped portion of the said tool. About mid-
way between the face of the hammer head a and the cutting edge of the axe
shaped portion we form a hole c of any convenient shape and size through the
whole depth of the central part or portion d of the tool, into which hole ca
handle or shaft of any suitable shape, size and material is fitted for the purpose-
of being able to make use of the said tool.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
The construction of a tool for use in mines, collieries or the like places, of or from
wrought iron, wrought or cast steel or other suitable material or materials, which said
tool has an axe shaped portion at one end, and an elongated hammer head shaped
portion at the opposite end, the said tool being fitted for use to a handle or shaft made
of or from any suitable material, of any suitable shape and size, the different parts of
the said improved tool having somewhat similar proportions to each other as herein
substantially described, set forth and fully illustrated on the drawings hereunto
annexed.
