PROVISIONAL SPECIFICATION.
Improvements in Tool Handles.
1, EDWIN JAMES PARSONS, of Elmore, in the Colony of Victoria, Farmer
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved handle for tools, such as the bits usually
used with the brace. My handle consists of an outer case, which is hollow and
has within a laterally movable part. Vertical openings to receive the tapered
shank of a bit or tool are provided in the case, and the movable part, the opening
being smaller at one side of the case than the other, to enable tapered shanks to be
firmly held in place when the movable part is adjusted. The said adjustment is
effected by having a screw threaded end to the movable part and a nut thereon
arranged so as to bear against the fixed outer case so that turning the nut will
have the effect of giving lateral adjustment to the said movable part and fastening
or unfastening the tool in the handle as may be required.

I, EDWIN JAMES Parsons, of Elmore, in the Colony of Victoria, Farmer, 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:-
This invention relates to an improved handle for tools, such as the bits usually
used with the brace. My handle consists of an outer case, which is hollow and
has within a laterally movable part. Vertical openings to receive the tapered
shank of a bit or tool are provided in the case, and the movable part, the opening
being smaller at one side of the case than the other when required to enable
tapered shanks to be firmly held in place when the movable part is adjusted.
The said adjustment is effected by having a screw threaded end to the movable
part and a nut thereon arranged so as to bear against the fixed outer case so
that turning the nut will have the effect of giving lateral adjustment to the said
movable part and fastening or unfastening the tool in the handle as may be
required.
In the accompanying drawings,
Figure 1 shows a view from beneath of the outer case A ;
Figure 2 shows a view from beneath of the inner movable part B fitting A ;
Figure 3 shows a perspective view of a milled head or nut C which screws on
to a screw threaded pin D which projects from one end of B, and is adapted to
pass freely through the corresponding end N of A;
Figure 4 shows a side view of the handle complete with a taper ended bit I held
therein

page_text: Figures 5 and 6 show respectively top and bottom views of the openings E, F, G, H
in A and B for the admission of the tapered bit.
As bits or tools inserted in this handle may be of any shape at their upper end K
I do not restrict myself to any particular shaped openings E, F, G, H but use such
openings as may be required to suit the shape of the bit or tool end. The arrange-
ment shown in the drawing has the advantage that the part K cannot slip upward
when in use, but the same advantage may obviously be secured by a projection
being provided on B and arranged to enter a recess which might be provided in K.
L is a slot in A and M a projection on B which is adapted to work in the slot, the
openings E, F, G H being thus kept in proper register.
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
claim is :-
1. In a tool handle a hollow case A having the apertures E, G and slot L
substantially as and for the purposes set forth.
2. In a tool handle an inner case B having slots F, H serew threaded pin D and
projection M substantially as and for the purposes set forth.
3. A tool handle consisting of the outer and inner cases A and B having suitable
apertures E, F, G H and adapted to be adjustably secured in position by a nut C
engaging with a screwed pin D substantially as and for the purposes set forth.
Dated this 12th day of September 1895.
