COMPLETE SPECIFICATION.
A New or Improved Letter File.
I, ANTON KOJER, of Komotau, Bohemia, in the Empire of Austria, 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 a letter file which can be opened and closed like a book,
so that the letters or other papers placed in it can be referred to without difficulty.
The advantages of this letter file over those at present in use are that it is
easier and more convenient to use, simpler in construction, and therefore cheaper-
to make.
In the accompanying sheet of drawings Figure 1 is an end view of a letter
file constructed in accordance with the invention, and Figure 2 a perspective view
of same.
The two covers a and b are connected together by a back e like ordinary book
covers. d are lugs or sockets fixed to the cover b or to the back c, and e is a rod
secured in the lugs or sockets d. On this rod e are pivotted two tubular parts f,.
and in corresponding positions on the cover a are fixed two spring strips g which
take at one end into the tubular parts f. On the cover a are also fixed the
springs which hold the letters or other papers firmly when the file is closed.
These springs are preferably bent at their outer free ends to prevent them
from injuring or tearing the letters or other papers. The parts g may be
made of elastic wire if preferred the tubular parts f being of a shape to
correspond.
When the file is opened at the proper place the front page of the letter or
other paper is directly exposed to view, and the back page can be read by turning
the sheet over as shown at i in Figure 1.
In order to place the letters or other papers in the file the free ends of the
springs 9 are drawn out of the tubular parts and the letters are passed over the-
latter and lie one on the other and can be inspected and turned over like the leaves.
of a book.
Instead of fixing the springs or wires g to the cover a they may be fixed to a.
rod in such manner that by pushing in the strips or wires the letters or other papers
are securely held in place. The said rod may be made of any suitable material..
It is not shown in the drawings.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed I declare that what I.
claim is :-
First. A letter file having metal bars or wires g fixed at one end to one of the-
covers and taking at the other end into pivotted tubular parts f, whereby the letters.
or other papers are held in the file book-wise substantially as described.
Second. In a letter-file of the kind herein described, the modification of the.
apparatus for holding the letters or other papers, which consists in fixing the-
spring strips or wires g to a stiff rod of suitable material instead of to the cover a,.
so that the said rod bears against the letters or other papers and holds them
securely when the said strips or wires g are introduced into the tubular parts f,.
substantially as described.
Third. In a letter-file of the kind herein described, the use of one or more:

or other papers securely when the file is closed, substantially as described.
Dated this 13th day of April 1896.
