Improvements in and connected with Handles or Holders for Chisels,
Screw Drivers, Boring Bits, and certain other Hand Tools.
I, CHRISTOPHER WILLIAM CLARK, of 127 and 128, Great Charles Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention consists of the hereindescribed improvements in and connected
with handles or holders for chisels, screw drivers, gouges, boring bits, spanners and
all other hand tools which require to have a handle or holder fixed at one end.
My said invention may also be applied to hand braces for holding the boring bit or
other tool therein. My said improved handle or holder is so constructed and
arranged that any one of the said tools can be quickly fixed thereto or removed
therefrom and replaced by another tool. Thus one handle serves for use with a
great many different tools and the necessity for a separate handle for each tool is
obviated.
My invention is carried out as follows:-The part of the handle or holder in which
the tool fits is made of cylindrical form and slightly taper that is smaller at the
front end and fitting on this taper part there is a removable socket of corresponding
taper form inside. The said taper part is made with a cross slot in which the
shank of the tool fits the said shank being made of a flat section so as to fit in the
cross slot.
To fix the tool to the handle or holder the flat shank has first to be inserted in
the cross slot therein and then when the socket has been pushed on to the taper
part of the handle or holder the tool is effectually secured but can at any time be
quickly removed by first removing the socket. The edges of the shank part of the
tool which fits in the handle or holder are made slightly inclined to correspond
with the taper form of the handle or holder and with the socket so as to prevent any
side play.
When the tool (as in the case of a wide chisel) is so wide that the socket will not
pass over the front end of the same, the socket has then to be made with two
fongitudinal grooves inside so as to permit of its being threaded on to the slightly
taper shank of the tool which otherwise would be impossible.
