PROVISIONAL SPECIFICATION.
Improvements in Tools of the Pick and Hammer Type.
I, OSMOND EDWIN BEAN BOYCE, of Karachi, in the Province of Sind, British
India, Engineer and Contractor, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in tools of the pick and hammer type, and
is applicable to all tools characterised by a head at right angles with the handle;
such as picks, mining mandrils, axes, adzes, hoes and the like.
In carrying the invention into effect the central portion of the tool head, or
that portion of it which is immediately made fast to the handle or helve, is
Tshaped in section. The respective end of the handle is slotted in the direction
of its length and strengthened by a stout metal ferrule, itself slotted to receive the
central web of the T. A socket is or may be formed at the bottom of the slot
in the handlo, to receive a corresponding extension on the central web.. The end
of the ferruled landle shaped to bed closely up to the under side of the side
flanges of the T. Head and handle are held together by means of a removable
cotter standing in transverse holes, a socket formed by transverse holes through
the ferruled end of the handle and a hole through the central web of the T, the
three being aligned with each other when the head and handle are in their respective
working positions.
A tool head is, according to the present invention, made of a T section for as
much of its length as may be practicable. The central web may be reduced to
merely a strengthening ridge if desirable:
The above described ferrulo and handle end therein, may be replaced by a socket
of the same conformation, the socket being held to the handle by any suitable
means or a series of interchangeable sockets may be adapted to one and the same
liandle.
The invention further includes a provision for shortening or clianging the bit of
say a pick. The actual bit is socketted at its rear end and the head' is shaped to
fit therein, the two being held together by a removable cotter.

Improvements in Tools of the Pick and Hammer Type:
I OSMOND EDWIN BRAN BOYCE, of Karachi,, in the Province of Sind, British
India, at present residing at No. 2 Balimain Street, Knowle; Bristol; in the County
of Gloucester, Engineer and Contractor, 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 :—
My invention relates to improvements in tools of the pick and hammer type!
It is applicable to all tools characterised by a head at right angles with the handle
or helve, such as picks, mining mandrils, axes, adzes, hoes, haminers, and the like:

page_text: The first part of it relates to an improved device for holding handle or helve
and head together. In carrying it into effect, the central portion of the tool head,
or that portion of it which is immediately made fast to the handle or helve, is
Tshaped in section. This T section extends through as much of the length of
the tool head as is practicable or desirable. The depth of the central wob of the Ṭ
may be reduced until the latter is only a strengthening ridge, whenever such
reduction may be desirable.
The respective end of the handle is slotted in the direction of its length and
strengthened by a stout metal ferrule which is also slotted to receive the central
web of the T. A socket is, or may be, formed at the bottom of the slot in the
handle, to receive a corresponding extension of the above mentioned central web
of the T. The head and the handle are held together by means of a removable
cotter standing in a socket formed by a transverse hole through the ferruled end
of the handle and the central web of the T, the three holes, aligning with each
other when the head and handle are in their respective working positions.
The second part of the present invention relates to a provision for changing the
bit or blade, or whatever it may be, at either end of the tool head, for another
of a different size or shape. The bit, or its equivalent in this respect, which it is
desired should be capable of being either shortened or changed, is socketted at its
rear end, that is the one opposite to the working end, and the respective end or
nose of the head is shaped to fit into such socket. A removable cotter is provided'
for holding the two together by standing in a socket occupying an analogous
position to the one described above with reference to the tool head and handle
socket.
Referring to the accompanying figures, which are to be taken as part of this
specification and read therewith,
Figure 1 is a side elevation of an ordinary pick made according to the present
invention:
Figure 2 is a front elevation, partly in section, of handle, socket, head and cotter :
Figure 3 is a front elevation of a handle and socket only:
Figure 4 is a plan corresponding with Figure 1:
Figure 5 is a plan of the head only of Figures 1 and 4:
Figure 6 is a plan of the handle socket:
Figure 7 is a transverse vertical section of the head through the cotter hole :
Figure 8 is a side elevation of an ordinary phaurah or hoe and pick :
Figure 9 is a plan thereof:
Figure 10 is a side elevation of a platelayer's pick and beater-the former being
removable-made according to the present invention :
Figure 11 is a side elevation of a removable pick detached from the head.
Figure 12 is an end view of it.
Figure 13 is a side elevation of a removable beater detached from the head.
Figure 14 is a plan of Figure 10.
Figure 15 is a side elevation of an engineer's hammer head made according to the
same invention.
A is the tool head. In Figures 1 to 7, this head is the blade of a pick; in
Figures 8 and 9, it is the blade of a combined phaurah and pick; in Figures 10 to 14,
it is a combined pick and beater; while in Figure 15, it is a hammer head. The
object of illustrating so many applications of the invention, is to emphasize the fact
the latter is not limited to any particular tool but only to a particular type of tool
-the one specified above. The T section of the head is clearly shewn in
Figures 2 and 7; a, a being the flanges; and b, the central web of the T.
The influence of the conformation of the bead upon the respective lengths of the
head and of the T section in it, is disclosed by a comparison of the heads illustrated in
Figures 1. to 14, with that illustrated in Figure 15. In the former, it is practicable
for the section to extend nearly up to the points c, c, vanishing just before it reaches
them, while in the case of the hammer head it may be desirable that it should stop at
the necks d, d.

page_text: E is the tool bandlo. Tho tool-head end of it is larger than heretofore, because of
the substitution, by the present invention, of the improved method of holding head and
shaft together, for the spigot and eye method hitherto in use. e is a central slot down
the said end. It is aligned with the working position of the head. e' is the socket at
the bottom of the slot e in the direction of it along the handle E. is the
corresponding extension of the central portion of the web b. The contour of the slote
corresponds exactly with that of as much of the web b as is destined to fit in it; and
the contours of the extensions.e' and 6' with each other, likewise. F is the stout
metal ferrule fitting, tightly on the tool-head end of the shaft E. It is slotted and
shaped in continuation of the above described slotting and shaping of the said end.
The function of the ferrule F is the usual one of ferrulos, viz. to fortify the shaft
end against being wrenched or split. Further, the face of the ferruled end is
shaped to bed up truly against the flanges a, a, when the web b and the extension b¹
are in the slot e and the socket el, respectively. G is the removable cotter; and g, its
socket. This latter is composed of the two transverse holes g', g" in the sides of
the ferrule F and the handle E, and the one transverse hole 9 in the web b.
The second part of the invention is illustrated in Figures 10 to 14. Figures 10,
11, 12 and 14 show its application to the pick end of a combined pick and
beater. a¹ is the pick in question; and a³, the socket at its rear end. is the
nose of the head shortened on that side of the shaft to receive the detachable bit
and over which the socket a fits tightly. a is the cotter which holds the pick to
the head; and a³, its socket. Figure 13 illustrates a detachable beater. This
detachability may be applied to any bit or blade, or whatever it may be at, and to
either or both ends of the tool head.
The above described combination of ferrule and handle end therein, may be
replaced by a socket of the same conformation, the socket being held to the handle
by any suitable means or a series of interchangeable sockets may be adapted to
one and the same handle.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
olaim is-
1. The combination of tool head, handle, ferrule and cotter, as set forth.
2. The combination of tool head, detachable bit and cotter, as set forth.
3. The combination of tool head, handle, ferrule, cotter and detachable bit and
cotter, as set forth.
4. The hereinbefore described improved device for holding tool handle and head
together.
5. The hereinbefore described improved provision for changing either or both ends
of a tool of the type specified.
6. The combination of the hereinbefore described improved device for holding
tool handle and head together with the hereinbefore described provision for ohanging
either or both ends of a tool of the type specified.
7. The combination of tool head, socket substitute for the ferrule and handle end
therein, or series of interchangeable socket substitutes, as set forth.
