PROVISIONAL SPECIFICATION.
Improvements in and Connected with Portable Copying-presses.
1, ALBERT BLOCH, of 1 Boulevard Saint-Denis, Paris, France, Merchant, do hereby
declare the nature of this invention to be as follows:-
My invention bas for its object an improved construction of copying-press, which is
extremely simple, cheap, easy to work, and very portable, said press being specially
useful for commercial-travellers, excursionists, and the like.
In a press constructed according to my invention, there is a cylindrical core of
wood, or metal, along one of the generatrices of which are fixed on hooks, provided
for the purpose, the metallic back of a book of sheets of copying paper held between
two sheets of a strong fabric.
The back is fixed by a pin
or pivot in a head-piece of the core, which is furnished
with a handle, and is retained at the opposite end by a small pivotted latch or catch.
This back may itself be formed in two pieces, longitudinally, to allow each sheet to be
removed separately.
The outermost sheet, which is of larger dimensions, terminates in a metallic bar or
binding piece formed like a hook in section, and destined to engage or hook on to a
kind of counterpart or hook fixed to the interior wall of a sheath or tube. Now,
when the handle is turned in one direction traction is exerted by the core upon the
whole of the sheet, and therefore a strong pressure on the whole of the sheets of
copying paper in the book.
It is therefore sufficient to effect the preliminary operations usual with all copying
presses, and to then apply the pressure by partially turning the handle. The leaf of
the letter book is damped with a wet cloth, or otherwise, the letter to be copied is
inserted, and the whole is introduced into the sheath or tube, which is turned by the
handle in the proper direction. The two hook-shaped bars or binding pieces tako
into each other and traction is produced with accompanying pressure, as has just been
stated.
The letter book can he employed in the same way upon any similar cylindrical core
which would therefore form an integral part of the invention.
COMPLETE SPECIFICATION..
Improvements in and Connected with Portable Copying Presses.
I, ALBERT BLOCH, of 1 Boulevard Saint-Denis, Paris, France, Merchant, do hereby
declare the nature of this Invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment, reference being had to the accompanying drawings and to the letters and figures
marked thereon, that is to say :-
My invention has for its object an improved construction of copying press which is
extremely simple, cheap, easy to work, and very portable. It is especially useful for
commercial travellers, excursionists, and the like.
The accompanying drawings will render its construction and working readily
understood.
Fig. 1 is a plan of the press unfolded ready to receive the letter to be copied.
Fig. 2 is a transverse section thereof.
Fig. 3 is a view, partly in section, shewing the press rolled up during the copying,
or when not in use.
Fio 4 is a transverse section thereof

page_text: This press consists of a cylindrically shaped wood or metal core a, furnished, in the
direction of its length, with spikes or hooks on which are fixed the metallic back c of
a book of sheets of copying paper d, held between two sheets f, f¹, of strong fabric.
The back is fixed, by a stud or pin 7, to the head piece h of the core which is
furnished with a handle 7, and it is retained at the opposite end by a small pivotted
latch or catch k. This back may itself be formed of two longitudinal pieces to allow
of each sheet being removed separately.
The larger outer sheet f terminates in a hook-shaped metallic bar or binding-piece l,
destined to engage with, or hook onto, a counter part or hook m fixed to the interior
wall of the sheath or tube n (figs. 3 and 4).
Now, when the handle j is turned in the direction of the arrow (fig. 4) traction is.
exerted by the core upon the whole extent of the sheet, and therefore great pressure
is brought to bear upon all the sheets of copying-paper in the book.
It is therefore sufficient to effect the preliminary operations usual with all copying
presses, and to then apply the pressure by partially turning the handle. The leaf
of the letter-book is damped with a wet cloth, or otherwise, the letter to be copied
is inserted, and the whole is introduced into the sheath or tube and the handle turned
in the direction of the arrow (fig. 4). The two book-shaped bars or binding
pieces l, m, take into each other, and the traction is produced with accompanying
pressure as has just been stated.
The letter-book can be employed in the same way upon any similar cylindrical core,
which would therefore form an integral part of the invention.
Instead of providing the letter-book with a metallic back, and causing the outer
leaf of the book to terminate in a metallic bar or binding piece, 1 may advantageously
employ the following arrangement.
I provide a sheet of strong fabric, one end of which I furnish with a metallic
back, perforated at various parts, and to the other end 1 fix a hook-shaped metallic
binding piece. I further use a book covered with fabric and furnished with holes
corresponding with those in the metallic back of the sheet of fabric and with the
spikes or hooks on the core, as above described.
The copying book is fixed on the spikes or hooks, the sheet of fabric is placed
above the book and the proceedure is then similar to that above stated.
The advantages of this arrangement are the following:
The metal edged fabric serves indefinitely and does not need to be changed with
each letter book.
The letter-book becomes easier to work, having neither metal back nor ends, and
can therefore be made more cheaply.
Having now particularly described and ascertained my invention and in what
manner the same is to be performed, 1 claim:-
1. The improved portable copying press having its parts arranged and combined
to operate substantially as described and shewn with reference to the drawings
annexed.
2. The improved letter-book formed as heroin described and shewn, and adapted
for use with the portable copying-press above claimed, or with other like press.
Dated this 18th day of July 1889.
