Mandrils, and the like.
THOMAS OLIVER DIXON of 68, Walter Road Swansea, Engineer and THOMAS
JOHNS of 6 Benthall Place, Swansea, Railway Foreman do hereby declare the.
nature of this invention to be as follows:-
The improvement consists in so cutting part of the plate forming the head of the
axe, adze, etc. in the direction of its length and forcing out the parts so cut in such
a manner that the parts so cut and forced ont shall and may form the eye or hole
through which the handle is inserted and against the sides of which the inserted
part will grip.

Improvement in the Construction of Axes, Adzes, Picks, Colliery
Mandrils, and the like.
WC, THOMAS OLIVER DIXON of 68, Walter Road, Swansea, Engineer, and
THOMAS JOHNS of 6, Benthal Place Swansea, Railway Foreman 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 relates to certain improvements in the construction of picks, axes,
adzes, colliery mandrils and the like.
Our said invention consists in so cutting suitable steel or other plates as to form
slots of a suitable size; preferably by means of a punch with cutting projections
and corresponding hollows so as to form an eye or hole through which a handle,
machine part or other device may pass through or be fixed to, also providing a
projection and corresponding hollow in die to form a head to stand blows of any
required force.
We will now proceed to refer to the annexed drawing from which the nature of
our said invention will be clearly understood.
Figs. 1, 14, 1B, 1C, represent views of an axe made from a steel plate by the
process hereinafter to be described and ascertained.
Figs. 2 & 3 are sections through movable and stationary parts of punch.
Fig. 4, a section through die.
Figs. 5 & 6 are plans of movable and stationary parts of punch.
Fig. 7 is a section through movable and stationary parts of punch; through die,
and an automatic delivering appliance.
It is preferred to place the steel or other plate, over, and resting on the die G
which is fixed to the part of punch B which is provided with two hollows C C
and three cutting projections D D D; the movable part, F, of punch is provided
with three hollows D₁ D' D' and two cutting projections C C which fit accurately
into the hollows C C on the part B. By having a projection E, shown on B, and
the corresponding hollow E' on F, the axe or other tool receives a head L of suit-
able strength to stand any required blow.
On setting the punching machine in motion the movable part F descends on the
steel or other plate cutting and forcing out the pieces K K which receive their

page_text: form or shape on the simultaneous contact of the cutting projections C₁ Cand
hollows CC with the two sides of the steel or other plate; the parts J J J
receiving their form on the simultaneous contact of the convex projections D D D
and the hollows D' D' D' with the steel or other plate..
The parts J J J and K K free at neither end forming an eye or hole through
which a handle may be inserted.
The simultaneous contact of the steel plate with the projection E and hollow E'
form the said head L to stand blows.
It is unnecessary for us to more fully describe the construction of machines to
which our said invention is applicable; inasmuch as such machines are well known
and understood; neither do we claim each of the several parts of the apparatus
herein before described as being of our invention separate and apart from its
application to our said invention; but
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 :-
Firstly. The special construction of the eye or hole to allow of a handle or any
other machine part or any other device in connection with axes, adzes and the like.
Secondly. The combination of the head L with the improved eye J K.
