page_text: I, ARTHUR WILLIAM WATSON of 16 Ferron Road, Kenningball Road, Clapton,
in the county of Middlesex, Chemist, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the construction of a convenient and portable apparatus
for press-copying letters or other documents, which apparatus is very effective
and will occupy but little space and can therefore be easily carried about when
travelling.
In carrying out my invention I construct the apparatus of a rectangular frame
within which I place a moveable plate; between one side of the said plate and the
inside of the fraine and at about the centre thereof I pivot a lever having on its
face a series of cam shaped projections or inclines or wedges adapted to move over
correspondingly shaped projections or wedges on the surface of the moveable plate,
so as to cause the same to be moved to give the required pressure; the end of the
Buid lever extends outside the said frame so as to allow of rotating the said cams
or inclines; suitable springs are provided for pressing the plate into its open
position when not operated by the lever.
-
To make use of an apparatus of this construction, the apparatus being in its
open position, the manuscript or the like to be copied with the paper to receive the
copy in the usual manner is placed between the frame and the plain side of the
moveable plate, and the lever being then rotated the cams or wedges thereon
moving over the corresponding cans or wedges in the plate as herein-before
described will produce the required pressure with the apparatus in any position ;
to remove the manuscript and copy the lever is moved in the reverse direction.

I ARTHUR WILLIAM WATSON of 16 Ferron Road, Kenninghall Road, Clapton,
in the county of Middlesex, Chemist, 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 the construction of a convenient and portable apparatus
for press-copying letters or other documents, which apparatus is very effective
and will occupy but little space and can therefore be easily carried about when
travelling.
In carrying out my invention I construct the apparatus of a rectangular frame
or case within which I place a moveable plate; between one side of the said plate
and the inside of the frame and at about the centre thereof I pivot a lever having
on its face or faces a series of cam-shaped projections or inclines or wedges adapted
to move over correspondingly shaped recesses or wedges on the surface of the
moveable plate and inside of the frame so as to cause the moveable plate to be
moved to give the required pressure; the end of the said lever extends outside the
said frame so as to allow of rotating the said cams or inclines; suitable springs
are provided for pressing the plate into its open position when not operated by
the lever.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 is a plan
and figure 2 an end view of a copying apparatus made according to my invention;
figure 3 is a section on figure 1. Similar letters in all the figures represent
similar parts.
a, is the rectangular frame or case; b, the moveable plate therein; c, c, are
projections on the plate b, such projections working in the recesses d, d, in the
ends e, e, of the frame or case; f, is the lever pivotted at g, between the plate b,
and one side of the frame or case; h, h, are the cam-shaped projections or inclines
or wedges on the lever f, and i, i, are the correspondingly-shaped surfaces on
the moveable plate b and side of the frame or case; j, j, are springs in the
recesses d, d.
To make use of an apparatus of this construction, the apparatus being in its
open position, as shewn in figures 1 and 2, of the drawing, the manuscript or the
like to be copied with the paper to receive the copy in the usual manner is placed
in the space k, between the frame a, and the plain side of the moveable plate b
and the lever f, being then rotated into the position shewn by the dotted lines in
figure 1 the cams or wedges h, h, thereon moving over the corresponding cams or
wedges, i, in the plate b, and side of the frame as herein before described will
produce the required pressure with the apparatus in any position; to remove the

page_text: manuscript and copy, the lever is moved in the reverse direction and the plate b,
will be carried back to its normal position by the springs j, j.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The manufacture and use of the improved apparatus for press copying letters or
the like as herein before described and illustrated in the accompanying drawing.
