Improvements in Picks and the like Tools.
I, THOMAS DAWES, of Wrockwardine Wood, Oakengates, in the County of
Salop, Pit Head Machine Man, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the construction and arrangement
of picks and the like tools for miners, and other similar purposes and is applic-
able to such tools having a pointed or other shaped beak at each end, or as in
some cases having a hammer like shaped head at one end.
°
In this my invention I make and arrange such ends to receive interchangeable
removable points or terminal tools, such as variously shaped points, flats or
cutting tools such as an axe or adze &c. Where one of such ends is shaped as a
hammer it may be formed in its proper shape for use if desired, that is, having
no removable terminal.
The head or block is preferably a malleable cast head in which is formed the
eye to receive the haft, which said eye is preferably made taper, being smallest
towards the handle, so that the haft is passed through from the upper side; hence
any centrifugal tendency only serves to fasten it the more. This head is suitably
shaped to receive the attachable ends and as far as possible is made to conform
with the usual shape of such tools. In cases where a pointed pick is required,
I prefer to make such a point in a short length having a screwthreaded part
which may be screwed into a hole formed in the shortened end of the beak of the
head. If desired in the said beak at a short distance from the end a hole may be
made in which may lie a screwnut which may be screwed upon the end of the
screwed pin part of the removable point, in which case I may make the screwthread
in the head portion, and that in the nut to vary, that is, one may be a right hand
and the other a left hand thread. A cotter or other similar fastening may be used.
In some cases I may form the hole in the beak so that the removable point may
be passed into its place from the inside, that is, through the eye opening, so to
speak. In such cases may be necessary also to make the hole continue through
the head part to the exterior of the opposite side to that in which the point is
placed. In these cases the point is placed in position before the haft is inserted,
and usually a plate is put upon the haft at that part against which the pressure
from the inner end of the inserted point will be directed.
Thus by these means, a number of renewable points of similar, or varied
character may be readily carried in the pocket, so as to replace damaged ones,
or to serve for a change of work as the case may be; and thus provide a useful
tool either for mining or other trades or domestic purposes.
Further, where desired in the side of the head provision may be made to
carry a spanner or key by which the said points may be put in or removed.
