PROVISIONAL SPECIFICATION.
Improvements in and relating to Copying-presses.
I, WILLIAM JUNGE, of 12, Ampthill Square, London, N.W., Civil Engineer,
do hereby declare the nature of this invention to be as follows :-
My invention relates to an improved copying-press substantially consisting of two
sheets of metal or other suitable material, which, being bent, exert a comparatively
great pressure upon the paper placed between them.
In carrying my said invention into practice I provide a sheet of metal, such
as steel or other elastic or flexible material made of somewhat larger size than
that of the sheets for the copies to be taken. Along two of its edges I attach,
either on one or both sides, ribs or flanges of any suitable section and shape by
means of rivets, screws or solder. Such ribs or flanges may also be obtained on
one side of the sheet by bending the said edges. In lieu thereof I may furnish
these edges with rows of pins for the same purpose. One of the ribs, flanges or
rows of pins may moreover be replaced by a hinge.
The second sheet, made of the same or other material, is of such length or width
as to fit between the before-mentioned flanges or other projections and may, if
desired, be hinged at one of its edges to the other sheet. For the purpose of
strengthening the edges of the second sheet, which adjoin or come in contact with
the flanges or projections on the first sheet, such edges may likewise be furnished
with ribs or flanges. In case use is made of pins projecting from the first sheet
the second sheet may extend beyond such pins and pierced with holes through
which the latter project when the two sheets are put together, and which may be
strengthened by eyelets, bushes, hollow rivets or the like.
In order to produce copies with this improved press the prepared papers are
placed between the two sheets held in their relative positions by the aforesaid
flanges, ribs, hinges or pins at the edges. Then the operator takes hold of the
sheets by these edges and bends them, thereby producing a great pressure upon
the papers between them.
It will be observed that the copying-press thus constructed is extremely simple,
compact, cheap, durable and efficient, and enables the copying to take place very
rapidly with a minimum amount of work.

COMPLETE SPECIFICATION.
Improvements in and relating to Copying-presses.
WILLIAM JUNGE of 12 Ampthill Square, London, N.W., Civil Engineer,
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 :—
My invention relates to an improved copying-press, substantially consisting of
two sheets of metal or other suitable material, which, being bent, exert a
comparatively great pressure upon the paper placed between them.
By way of example I will hereinafter describe two constructional forms of my

page_text: improved copying-press, one being employed for copying on loose leaves only,
and the other for copying on the leaves of a book as well as on loose leaves.
In the accompanying drawing, wherein similar letters of reference designate
corresponding parts,
Fig. 1 represents a plan of a copying press designed for loose leaves.
Fig. 2 is a side view of the same.
Fig. 3 shows how this press is bent to a horseshoe shape in order to produce
pressure.
Fig. 4 is a plan showing the construction of my press for copying on the leaves
of a letter book.
Fig. 5 represents a side view of this press.
In carrying my said invention into practice I provide a sheet a of steel or other
elastic or flexible material, made of somewhat larger size than that of the leaves
on which the copies are to be taken. Along two of its edges b and c I attach,
either on one or both sides, ribs or flanges d and e of any suitable section and shape
by means of screws, rivets, or other suitable means, Figs. 1 to 3. Such ribs or
flanges may also be obtained by bending the edges b and c, or if the sheets are of
canvass or like flexible material the said ribs or flanges may be sewed in or
otherwise fastened to the same. In lieu thereof I may also furnish one or both of
the edges b and c with projections or abutments f, Figs. 4 and 5. As represented
in these two figures, the sheet a made of canvass has abutments formed at the
extremities of a strip g of metal at one edge, and a strip of metal or other suitable
material at the other edge capable of being folded or laid round the edge k of
the second sheet i. The flanges d and e at the edges of the sheet a, Figs. 1 to 3,
and the abutments and second strip 1, Figs. 4 and 5, serve for the purpose of
giving sufficient hold to the second sheet i and keeping it in the proper position
when the two sheets are bent so as to produce pressure upon the paper placed
between them.
The second sheet i, made of steel or other elastic material, is of such length as
to fit between the before-mentioned ribs, flanges or other abutments at the edges
of the sheet a. For the purpose of strengthening the edges k of the sheet i, which
adjoin or come in contact with the ribs, flanges or other abutments at the ends of
the sheet a, such edges may likewise be furnished with ribs, flanges or the like.
When use is made of pins projecting from the first sheet a the second sheet i extends
beyond such pins and is pierced with holes through which the latter project when
the two sheets are superposed, and which may be strengthened by eyelets, bushes,
hollow rivets or the like. In this case the sheets may at will be bent in any
direction to produce pressure.
It is obvious that the two sheets a and i may be fastened together along one of
their edges by hinges or other means.
In order to produce copies on loose leaves with this improved press the prepared
papers, as indicated in dotted lines, are placed between the two sheets a and i held
in their relative positions by the ribs, flanges, hinges, pins or other suitable abut-
ments at their edges. Then the operator takes hold of the sheets by the edges
and bends them, Fig. 3, thereby producing a comparatively great pressure upon
the paper between them. To use this press for the leaves of letter books, I first
put some dry leaves and then the prepared paper between the two sheets,
whereupon the press is bent to the position indicated by the dotted line in
Fig. 5.
It will be observed that the copying press thus constructed is very simple, cheap,
light, portable, compact, durable, requires little power for its operation, can be
easily manipulated and produces clear copies in the shortest time.
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 :-
First. A copying-press comprising two superposed sheets of steel or other

page_text: elastic material, held in engagement at their ends, and which on being bent produce
a pressure upon the paper placed between them.
Second. A copying-press comprising a sheet of canvass or other flexible
material, and a sheet of steel or other elastic material, which are held in engage-
ment at their ends, and which on being bent produce a pressure upon the paper
placed between them.
Third. A copying-press comprising two sheets a i of steel or other elastic
material, one of these sheets being provided at its ends with projections or abut-
ments d between which the second sheet fits, substantially as and for the purpose
hereinbefore set forth with reference to Figs. 1 to 3 of the drawing.
e,
Fourth. A copying-press comprising a sheet a of canvass or other flexible
material and a sheet of steel or other elastic material, one edge of the flexible
sheet being provided with a strip g of metal, wood or the like which presents lugs,
projections or other abutments f for the elastic sheet, and the second edge being
also provided with a strip h of metal, wood or the like designed to be laid round
the edge of the said elastic sheet, substantially as and for the purpose hereinbefore
set forth with reference to Figs. 4 and 5 of the drawing.
Fifth. A copying-press constructed and operating substantially as hereinbefore
set forth with reference to the accompanying drawing.
