PROVISIONAL SPECIFICATION.
A Tool having the Dual Capabilities of Cutting Holes in the Metal
Corners (or Tenons) of School Writing Slates and also of
Screwing Up Screws through such Metal Corners, or any other
part of a Writing Slate requiring Screws, for Attaching the
Slate to the Frames.
I JAMES MAXWELL of '81 Holcombe Road, Haslingden, in the County of Lancaster,
School Writing Slate Maker, do hereby declare the nature of this invention to be as
follows:-
By means of a small straight.steel.tool, the metal being twisted (as in a twist drill).
one end being shaped chisel like, the faces of the chisel (so to speak) being brought
down to a razor edge, I am enabled to cut through the slate frame, and also cut
through the thin metal plates (or tenons) which are embedded in the slate frame..
This tool is inserted in a suitable chuck, rotated by power and lifted up & down at
will. This describes the tool as a cutter. Now by taking a small screw, and
inserting it into the orifice made by the cutter, I (whilst the tool is rotating rapidly)
bring it down upon the head of the screw, so that by its rotation, the fine razor edge
of the tool, at once for itself finds the nick in this small screw, screwing it up
instanter. The tool alternately cutting out a suitable hole in the slate frame and the
metal, and securing the metal corner by screwing to the frame. Sometimes I make
this tool from plain steel (i.e. not twisted) the same work is done but not so
expediously.

A Tool having the Dual Capabilities of Cutting Holes in the Metal
Corners (or Tenons) of School Writing Slates and also of
Screwing Up Screws through such Metal Corners, or any other
part of a Writing Slate requiring Screws, for Attaching the
Slate to the Frames.
I, JAMES MAXWELL, of 81 Holcombe Road, Haslingden, in the County of Lancaster,
Writing Slate Maker, 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 stateinent :-
My invention relates to a tool having the dual capabilities of cutting holes in the
metal corners (or tenons) of school writing slates, and also of screwing up screws,
through such metal corners, or any other part of a writing slate requiring screws for
attaching the slate to the frames.

page_text: And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and figures
marked thereon.
Fig. 1, is a side view of the top chisel shaped end.
Fig. 2, is a front view of the tool.
Fig. 3, is a side view of the bottom chisel shaped end.
By means of a small straight steel tool, the metal being twisted c (as in a twist
drill) one end being shaped chisel-like a at top and bat bottom-the faces of the
chisel (so to speak) being brought down to a razor edge-I am enabled to cut through
the slate frames and also to cut through the thin metal plates (or tenons) which are
embedded in the slate frame. This tool is inserted into a suitable chuck; rotated by
power, and lifted up and down at will-this describes the tool as a cutter. Now, by
taking a small screw and inserting it into the orifice made by the cutter, I (whilst the
tool rotating rapidly) bring it down upon the head of the screw, so that by its rotation,
the fine razor edge of the tool, at once for itself finds the nick in this small screw,
screwing it up instanter. The tool alternately cutting out a suitable hole in the slate
frame and the metal and securing the metal corner by screwing it up to the frame.
Sometimes I make this tool from plain steel (i.e. not twisted) the saine work is done,
but not so expediously.
The chisel shape at both ends a and d of the metal, one end being twisted c and the
other plain b, so that if it suits the user better to reverse the tool after cutting through
the steel corner or tenon he may do so using the untwisted end for screwing in the
screws.
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 having the dual capabilities of cutting holes in the metal corners (or
tenons) of school writing slates, and also of screwing up screws, through such metal
corners, or any other part of a writing slate requiring screws for attaching the slate
to the frames, the combination of the plain shaft b twisted drill a top chisel-shaped
end a and the bottom chisel shaped end d, substantially as berein described and
according to the accompanying drawing.
2. In a tool having the dual capabilities of cutting holes in the metal corners (or
tenons) of school writing slates, and also of screwing up screws, through such metal
corners, or any other part of a writing slate requiring screws for attaching the slate
to the frames, the combination of a plain shaft 6 top chisel shaped end a and the
bottom chisel shaped end d, substantially as herein described.
3. In a tool baving the dual capabilities of cutting holes in the metal corners (or
tenons) of school writing slates, and also of screwing up screws, through such metal
corners, or any other part of a writing slate requiring screws for attaching the slate
to the frames, the combination of the various parts as described in the above
specification for the purpose specified.
