PROVISIONAL SPECIFICATION.
Improvements in Picks, Axes, Hammers, and similar Tools.
We, SAMUEL FIDLER, of 35 Kirke White Street, Nottingham, Miner, JOHN
ELLIOTT FIDLER, of Launder Cottage, 2 Launder Street, Nottingham, Miner,
and THOMAS SEVERN, of 230 Wilford Road, Nottingham, Manager, do hereby
declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the construction of picks,.
hammers, axes, and similar tools, and in the manner of fixing the pick or hammer
head to the socket. For the purpose of our invention the upper end of the
socket is made solid and square from the shoulders, and one of the shoulders of
the socket is slit or slotted to receive a wedge for fixing the pick or hammer
head thereto, and thus obtaining a firmer tool than has heretofore been made..
A hole made in or near the middle of the socket for convenience in casting
the same.
The wedge passes through the pick or hammer head, and holds it
against the solid upper end of the socket, and also passes through the slot in
the shoulder, and is thus more easily removeable than the wedges in any other
picks. The wedge can be replaced by a screw if the tool is required for ripping
or rock work, so as to obtain the greatest amount of firmness. The square portion
of the socket may be slightly narrowed or bevelled towards the shoulder which
is not slotted, and may be provided at the narrow end with a lip or projection
to fit the pick or hammer head and thus more securely hold it to the socket.

COMPLETE SPECIFICATION.
Improvements in Picks, Axes, Hammers, and similar Tools.
We, SAMUEL FIDLER, of 35 Kirke White Street, Nottingham, Miner, JOHN
ELLIOTT FIDLER, of Launder Cottage, 2 Launder Street, Nottingham, Miner,
and THOMAS SEVERN, of 230 Wilford Road, Nottingham, Manager, 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, reference being had to the accompanying drawings and to the letters.
and figures marked thereon, that is to say:
Our invention relates to certain improvements in the construction of picks, axes,.
hammers, and similar tools, and in the manner of fixing the pick or hammer head
to the socket, whereby an under-wedge that can easily get loosened, is dispensed
with, and the head can be taken off and replaced much quicker, and is much
There is also no swell
stronger and firmer, than in picks as hitherto constructed.
in the eye, or any inconvenient projection from the head.
For the purpose of our invention, the upper end of the socket is made solid and
rectangular or square from the shoulders, and one of the shoulders of the socket is
slit or slotted to receive a wedge for fixing the pick or hammer head thereto.
A hole may be made in or near the middle of the socket for convenience in casting
the same.
The wedge passes through the pick or hammer head, and holds it
against the solid upper end of the socket, it also passes through the slot in the
shoulder and is thus more easily removable than are the wedges in other picks.

page_text: The wedge can be replaced by a screw if the tool is required for ripping or rock
work, so as to obtain the greatest amount of firmness. The rectangular or square
portion of the socket may be slightly narrowed or bevelled towards the shoulder
which is not slotted, and may be provided at the narrow end with a lip or pro-
jection to fit the pick or hammer head, and thus more securely hold it to the
socket. The pick blades are preferably made of best Swedish steel and of several
sizes to fit the socket so that they can be changed when desired. The sockets are
preferably malleable iron castings, and the wedges are made of iron, steel, or any
suitable material.
And in order that our invention may be more readily understood, we will
describe the same fully with reference to the annexed drawings, in which:
Fig. 1 shows a pick constructed according to our invention.
Fig. 2 shows a modified construction of pick, and Fig. 3 an end view of same.
Fig. 4 is a longitudinal section of the socket, detached.
Figs. 5 and 6 represent the application of the invention to an axe or hatchet and
hammer, respectively.
a is the head or blade, and b the socket, the rectangular or square portion c of
which passes through the eye as shown, and is inclined or bevilled at d, and provided
with lip e. ff, are the shoulders of the socket, and g the wedge passing through a
slot or hole in one of the said shoulders. (Fig. 1) is the hole made for
convenience in casting.
In some cases, both ends d, d', of the rectangular or square portion c of the socket
may be inclined, and the head secured by a square-headed metal wedge or pin g'
with round tail g', forced through the eye and hole in the shoulder f, as shown
at Figs. 2 and 3.
The socket is preferably formed with wedges j, j, as shown at Fig. 4 to open
out the shaft or handle within the socket so as to secure it more firmly in position.
The heads of picks, axes, or similar tools, may be fixed to the socket by a screw k,
as shown at Fig. 5.
In applying the invention to a hammer, the end c of the socket may be made
square or round instead of oblong in section, and the wedge lie against one side or a
flattened portion or groove therein.
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:
1. The construction of picks, axes, hammers, and similar tools, in which a
wedge, or its equivalent, is employed and is adapted to pass through the eye of
the pick head and through a slot or hole in said socket arranged therefor, sub-
stantially as described, and shewn with reference to the annexed drawings.
2. The improved socket for picks, axes, hammers, and similar tools, con-
structed as hereinbefore described and as shown with reference to Figure 4 of the
drawings.
3. Our improvements in picks, axes, hammers, and similar tools, substantially
as hereinbefore described and as shown in the drawings.
