Device Combined therewith.
I OSWALD ASSMANN of Tegelen in the Kingdom of The Netherlands, 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 :-
This invention relates to files or holders for letters, newspapers, patterns or similar
papers or articles and it consists in an improved construction of file or holder more
especially adapted for the better retaining of the articles thereon and for the
removal or insertion when desired of any one or more of such articles at any part
of the bundle without disturbing or disarranging the remainder.
The invention
further consists in the combination with a file of this nature of a construction of
perforating device in the manner hereinafter referred to.
The accompanying drawing illustrates the improved file Fig. 1 being a cross section
thereof empty and without case or covering.
Fig. 2 a front view, and Fig. 3 a plan thereof.
Fig. 4 is a sectional side view on a smaller scale showing the file full and in a
covering
The file consists of two base frames, hinged together and held pressed together as
far as the knees or ledges a will allow, by a suitable spring f. In the said base frames
are set rows of pins z each pin to project sufficiently far, in an arc of a circle of which
the hinge is the centre, to just engage in a recess in the opposite base plate so that
even when the file is quite full any paper etc., may be removed from the top or bottom
of the pile or elsewhere without the other papers etc., above and below leaving the
pins in the respective base boards, those above being retained in place by the pins
set in the upper base board, those below on the pins set in the lower base board.
The pins may be set at intervals as illustrated, or the pins of each row may be set
close to respective pins in the other row, so that each pair of pins may pass through
the same hole in the paper. The cross section of the pins may in such case be semi-
circular so that the two together pass conveniently through a circular hole, or triangular
to pass into a square hole.

page_text: According to the number of holes to be made in the letters etc. to pass them onto
the pins 2 so many punches are correspondingly set on the back outer face of one of
the base boards. Over these punches is set the plate p, with corresponding holes, this
plate being held up to the spring preferably made by bending over part of said plate
to press on the base board. The plate p is hinged by lugs thereon through which the
rod hinging the base boards also passes. Under the plate pare the fingers m m.
The letter is put under the plate p and the latter pressed down by revolving with
lever the shaft with cranks k k. Punctures are thus made in the letter by the
punchest and on releasing the perforating device, the fingers m m remove the letter
from the punches ready to be placed on the file.
I do not confine myself to having all the pins z at the same distance from the
hinge, they may be at different distances, the punches t being correspondingly
arranged.
The file can be placed in a case M in book shape with back R, being fixed
by means of ears o. (Figs. 2 and 4) or it may be also mounted on a wall bracket.
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 :
1. A file or holder for letters, manuscripts, newspapers, patterns and other articles
comprising two systems of equally long teeth of optional cross section for holding the
objects, which systems are hinged together and held closed by the spring f the teeth
being shaped as arcs of circles, the centres of which lie in the said hinge and set at
equal or different distances from said hinge with abutments a a whereby the system is
held so that the points of the teeth of each row project beyond the bases of the teeth
of the other row substantially as and for the purpose set forth.
2. The combination with the said file of a perforating device comprising the
punches set on the back of the file, the hinged plate p and the crank shaft k k
substantially as set forth.
