COMPLETE SPECIFICATION.
Improvements in Letter-files.
We, GEORG EDUARD HEYL, Chemist, and MAX PAULY, Merchant, both of
No. 8, Salzufer, Charlottenburg, near Berlin, in the Kingdom of Prussia, Germany,
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 :-
The
Our invention relates to improvements in a device for filing hand-writings and
similar papers and the object of the same is to avoid punching holes in the collected
papers. In all appliances, which are in use until this day for filing letters, the
latter are either pierced by a hook or they are punched to have circular holes cut
out. The disadvantages that result from this manipulation are evident.
paper is weakened and will frequently tear out, and above all the writing may be
damaged, since the holes punched out may bear important letters or signs, not to
speak of the risk of torn-off pieces getting lost altogether. To obviate damages of
this kind we employ transparent cards each provided with a hole or eye, which are
gummed on to the top of the letters, with which the papers are hung up on a hook,
hereinafter more fully described.
:-
In the following description we refer to the accompanying drawing, in which
similar letters denote similar parts throughout the different views and in which :-
Fig. 1 is a longitudinal section of the suspension-eye,
Fig. 2 is a front-view thereof attached to a sheet of paper,
Fig. 3 is a front-view of the complete appliance,
Fig. 4 is a side-view, and
Fig. 5 is a perspective view of the same.
The suspension-eye is made of two equally shaped transparent cards b b, which
may be made of strong tracing-paper or linen or any other transparent material;
they are about an inch long and about a half of an inch broad, and are jointed
together on half-way by an intermediate piece of card. This half is provided with
a circular, neatly cut, hole a, which is strengthened by the intermediate card;
the other halves of the transparent cards bb are gummed on the inner side and
stand a little apart so as to permit the insertion of a sheet of paper to be fixed
thereunto. The application of this suspension-eye need scarcely be detailed, the
inner sides of the unconnected halves are made wet, the paper to be preserved is
inserted in between and all three pressed together, thus the paper is ready to be
filed. Should it now happen, that the cards b cover part of the writing, the
transparency of the same will permit the reading thereof. Also the danger of
tearing the paper will be reduced to a minimum, since that part, which is most
liable to be torn, is rather strengthened by the suspension-eye itself.
Figs. 3 & 4 illustrate a hoop c, which may have a diameter of about of an inch
in section and be about two or three inches long and one inch and a half high.
Being made of any elastic and suitable material as steel, brass, hardened caout-
chouc, or the like, this hoop is attached, either rivetted or screwed on, to a plate P
and is made in two parts by being cut across askew at d. By bending the upper
part a little aside, the two bevelled ends will separate from each other and thus
permit any paper to be filed, after which by releasing the hoop the same will close
on account of its own elasticity and the bevel of the ends. f is a plate or board
made of any suitable material, which is hung before the papers to keep them from
bulging out and also to keep off the dust. The same is provided with a loose
hook a, in order to also suspend it from the hoop c, the lower straight bar of which
has holes o, wherein the point of g may be hooked. A heap of letters being filed,
the board is pressed against them and the hook 9 allowed to catch into the next

page_text: hole. Two small bars and i are attached to the plate P to keep the papers from
spreading to the right or to the left. However we may dispense with these bars,
when giving the hoop c an oblong or square section and the hole of the suspension-
eye a corresponding shape.
We also may make use of more than one hoop c according to the size of papers
to be collected.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. As an article of manufacture: A suspension-eye consisting of two transparent-
cards united on one half-side carrying the eye-hole by an intermediate card and the
other halves being gummed on the inner side, as for the purpose set forth.
2. In a letter-file: The hoop (c) being made in two parts, of which the butting-
ends are bevelled and remain closed by the elasticity of the material and of which
the other ends are attached to a plate (P), in combination with suspension-eyes
made of transparent material, for the purpose of filing letters, as set forth.
3. In a letter-file: The combination of a hoop (c) provided with holes (o), a
board (f) having a suspension-hook (g) to fit into the holes (o), for the purpose of
holding the papers together, as set forth.
