Improvements in Picks, Mattocks, and the like Hand Tools.
I, JOSHUA BOWNES, of Press, near Clay Cross, in the County of Derby, General
Smith and Tool Maker, do hereby declare the nature of my said invention to be
as follows:-
Although my invention is applicable to a great variety of hand tools, it is more
particularly adapted to implements for mining and the like purposes which have
loose blades or bits fitting into the head in such a way that when they become
worn or broken they can easily be removed and replaced by other blades or bits
as circumstances may require.
I am aware that several inventions have been patented for the construction of
miners picks and similar tools with interchangeable bits or points and I lay no
claim to novelty with regard to this mode of construction, the essential feature of
my invention being the particular method by which I secure the haft of the pick
into the head or socket. I effect this in the following manner.
The head or socket of my improved pick I form in a manner somewhat similar
to that employed for picks which are fitted with loose bits and likewise made
taper to receive the haft which is inserted from the top end. When so inserted
the top of the haft fills the socket from a point slightly below the eye which is
made to receive the loose bit or bits. Into the space above the top of the haft
I then insert a loose fillet which fills up the intervening space between the top of
the pick haft and the top of the head or socket but projecting sufficiently through
the top of the socket to allow of its being driven downwards to tighten the haft
in position.
This loose fillet however is provided with a transverse slot to allow of the loose
bits and the wedge for securing the same, being passed into the socket, so that
when the bits are in position and keyed up, the action of the key would tend to
tighten the fillet upon the top of the haft, so that the key which is employed to
secure the loose bit or bits into the head of the pick, likewise secures the haft.

Improvements in Picks, Mattocks, and the like Hand Tools.
I, JOSHUA BOWNES, of Press, near Clay Cross, in the County of Derby, General
Smith and Tool Maker, do hereby declare the nature of my said invention, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Although my invention is applicable to a great variety of hand tools, it is more

page_text: particularly adapted to implements for mining and the like purposes which have
loose blades or bits fitting into the head in such a way that when they become
worn or broken then can easily be removed and replaced by other blades or bits
as circumstances may require.
I am aware that several inventions have been patented for the construction of
miners picks and similar tools with interchangeable bits or points and I lay no
claim to novelty with regard to this mode of construction, the essential feature of
my invention being the particular method by which I secure the haft of the pick
into the head or socket. I effect this in the following manner.
The nature of my invention will be better understood on reference to the
accompanying sheet of drawings in which
Fig. 1 is a side elevation of one of my improved picks shewing the blade and
haft secured in position.
Fig. 2 is a plan of the same.
Fig. 3 is a longitudinal section taken through the eye of the socket.
Fig. 4 is a transverse section of the same.
Fig. 5 is a side elevation of the loose fillet.
Fig. 6 is an end view of the same.
Fig. 7 is a plan.
Fig. 8 is a side view of the blade or bit.
The same letters refer to similar parts throughout the several views.
The head or socket, A, of my improved pick I form in a manner somewhat
similar to that employed for picks which are fitted with loose bits and likewise
made taper to receive the haft which is inserted from the top end. When so
inserted the top of the haft, B, fills the socket from a point slightly below the
eye which is made to receive the loose bit or bits, C. Into the space above the top
of the haft I then insert a loose fillet, D, which fills up the intervening space
between the top of the pick haft and the top of the head or socket but projecting
sufficiently through the top of the socket to allow of its being driven downwards
to tighten the haft in position.
This loose fillet however is provided with a transverse slot, E, to allow of the
loose bit or bits, C, and the wedge or key, F, for securing the same, being passed
into the socket so that when the bits are in position and keyed up the action of the
wedge or key would tend to tighten the fillet, D, upon the top of the haft, B, so that
the wedge or key, F, which is employed to secure the loose bit or bits into the head
of the pick likewise secures the haft in the socket, A.
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 ]
claim is:-
1. In picks, mattocks, and the like hand tools, the particular method by which
I secure the haft, B, of the pick into the head or socket, A, by means of a
fillet, D, in combination with the loose blade or bit, C, and the wedge, F, in the
manner and for the purposes substantially as herein described and illustrated in
the accompanying sheet of drawings.
2. In picks, mattocks, and the like hand tools, the arrangement and combination
of parts and appliances comprising the socket, A, fitted with the fillet, D, and the
wedge or key, F, by means of which the blade or bit, C, as well as the haft B,
may be secured in the socket, A, by the action of the said wedge or key in the
manner and for the purposes substantially as herein described and illustrated on
the accompanying sheet of drawings.
