PROVISIONAL SPECIFICATION.
New or Improved Instrument for Producing Stencils for the Repro-
duction of Writing, Drawings, and the like.
I, REUBEN CORSHAM, of 62 Skinner Street, Bishopsgate, in the City of London,
Duplicating apparatus manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a new or improved instrument for producing stencilled
writing or drawing in paper or other material, for subsequent reproduction in printing
ink, the said ink being caused to pass through the fine stencil holes on to a plain
sheet of paper in the manner well understood in connection with this class of work.
In order to produce the fine holes which form the writing or drawing, the stencil
paper is, according to one process, laid on to a plate which has a surface of sharp
points or lines, and the operator writes or draws on the paper with a hard pointed
stylus whereby the paper is finely perforated or cut through by the sharp points or
lines of the plate underneath wherever the point of the stylus passes.
According to my present invention, instead of employing a pointed stylus for
writing or drawing, as above described, Í employ a small wheel mounted in a suitable
holder or handle and free to revolve when used by the operator in writing or drawing.
The liability to tear the paper is very much reduced by the employment of the rolling
wheel on the rough surface instead of the pointed stylus and the writing or drawing is
executed with more freedom of action.

COMPLETE SPECIFICATION.
New or Improved Instrument for Producing Stencils for the Repro-
duction of Writing, Drawings, and the like.
I, REUBEN CORSHAM, of 62 Skinner Street, Bishopsgate, in the City of London,
Duplicating Apparatus Manufacturer, do hereby declare the nature of the said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying sheet of drawings, and to the letters and Figures marked
thereon, that is to say :-
This invention relates to a new or improved instrument for producing stencilled
writing or drawing in paper or other material for subsequent reproduction in printing
ink, the said ink being caused to pass through the fine stencil boles on to a plain sheet
of paper in the manner well understood in connection with this class of work. In
order to produce the fine holes which form the writing or drawing, the stencil paper
is, according to one process, laid on to a plate which has a surface of sharp points,
similar to the surface of a finely cut file, and the operator writes or draws on the paper
with a hard pointed stylus whereby the paper is finely perforated or cut through by
the sharp points of the plate underneath wherever the point of the stylus passes.
According to my present invention, instead of employing a pointed stylus for
writing or drawing on the stencil paper laid on a plate having a surface of sharp
points as above described, I employ a small wheel mounted in a suitable holder or
handle and free to revolve when used by the operator in writing or drawing.
Figure 1 of the annexed drawings is a front view, and Figure 2 a side or edge
view, both to a scale about six times full size of one of my new or improved
instruments.

page_text: A is the holder or handle to which is secured a pin or axis B projecting at any
desired angle therefrom. C is a small smooth wheel mounted on the said axis B and
free to turn easily thereon. This wheel Cis preferably rounded more or less on the
edge as shown.
By writing or drawing with the above described instrument on thin waxed or other-
wise suitably prepared paper laid on a plate having a surface of sharp points, the
smooth wheel C presses the paper against the surface of the said plate so that the sharp
points thereof perforate the paper at the parts where the said whel presses it against
the plate, and a paper stencil is thereby prepared similar to what is produced with the
hard pointed stylus above referred to; but the liability to tear the paper is very much
reduced by the employment of the smooth rolling wheel on the rough surface, instead
of the pointed stylus, and the writing or drawing is executed with more freedom of
action.
. Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I would have it under-
stood that I am aware that it is not novel to employ a wheel with a roughened edge to
prepare a paper stencil laid on a smooth plate; also that it is not novel to employ a
ball free to rotate in or on a holder and having a roughened surface to prepare a
paper stencil laid on a smooth surface, and also that it is not novel to employ a ball
free to rotate in or on a holder and having a smooth surface to prepare a paper stencil
laid on a roughened surface, and I make no claim to either of such devices, but I
declare that what I do claim is :-
The new
or improved instrument for producing stencils, consisting of a small
smooth wheel mounted on an axis carried by a handle or holder, as hereinbefore
described and illustrated in the drawings, hereto annexed.
