Improvements in Paper Files.
I ROBERT WALDSCHMIDT of Brussels, in the Kingdom of Belgium, Manu-
facturer of Paper Files, residing at 216 Rue du Progrès, Brussels 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 present improvements relate to that class of paper files, in which two or more
fast needles or pins are used in combination with an equal number of movable pins
bent at their upper end so as to meet the fast ones. The papers to be filed are
previously provided with the required number of holes by means of a special
perforator, and then pushed upon the pins after having been opened. By closing
them again, the papers may be devided at any place, so as to be partly upon the
fast pins and partly upon the movable ones, thus permitting, by reopening the
pins, to withdraw any desired letter, or to introduce a new letter in its proper
place.
The improvements more specially refer to a mechanism for opening and closing
the movable pins.
Fig. 1 of the aunexed drawing shows the paper file opened; Fig. 2 is a section
of the same; Fig. 3 is a perspective view of the mechanism; Fig. 4 is a separate
view of certain parts of the saine and Fig. 5 to 7 represent modifications.
a are the fast pins; b is a wire clamp for holding together the filed papers, and
e are the movable pins fixed to a bar d the ends of which are pivoted or hinged
in ears e of the plate f 9 is a finger secured to the hinged bar d and
engaging in an inclined slot h of a piece i fixed to a second bar k movable in slots
of the ears e. By pushing the sliding bar k to and fro, the finger g, together with
the hinged bar d, will be raised and lowered, thus opeuing and closing the movable
pins c.
The finger g and the piece i may be interchanged and instead of being fixed
longitudinally to the sliding bar, they may be placed transversely. In this case,
the bark should be rendered movable to and from the bar d by providing the same
with a pivot at one of its ends.
Fig. 5 shows a modification in which the hinged bar d is provided with a
projection having two inclined plans, whereas the sliding bar k possesses two
fingers m m acting upon the said plans and producing the opening and closing of
the pins c.
Fig. 6 shows the bar d provided with a tooth g', upon which presses a spring k
having two undulations, in which the tooth will fall and maintain the pins c in
their position when opened and closed.
In Fig. 7 the bar d is provided with a lever n either rigid or flexible, by means
of which the pins c may be opened and closed; the ear e having two notches o o',
which retain the lever n in the two positions.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a paper file having fast and movable pins for filing the papers alpha-
betically the mechanism for opening and closing the movable pins, consisting of
a hinged bar d and a sliding bar k, provided, the one with a finger g which engages

page_text: in an inclined slot h of a piece i fixed to the other bar, all substantially as described
and shown Fig. 1 to 4.
2. The modification of the claimed mechanism consisting of a hinged bar d having
a projection with two inclined plans, in combination with a sliding bar k having two
fingers m m', Fig. 5.
3. The modification indicated Fig. 6 in which the hinged bar d possesses a
tooth g' upon which presses a spring having two undulations for catching said
tooth.
4. The modification shown Fig. 7 in which the hinged bar d is provided
with a lever n which is held in its position by two notches oo' of the ear e all
substantially as set forth.
Dated this 30th day of December 1895.
