PROVISIONAL SPECIFICATION.
Improvements in Files for Papers and Documents.
I, MAX KELLER, of 15, Grosser Kornmarkt, Frankfurt on Main, in the Empire
of Germany, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to provide a file for holding papers and
documents together which file is more durable and simple in construction and
more easily manipulated than are files as hitherto made.
The file has two uprights or vertical tubes secured to the base, and two curved
moveable lever arms which can be turned in one direction so as to meet the
uprights or vertical tubes for holding the papers or documents in place or in the
other direction so as to leave the uprights or vertical tubes for the removal of
the papers or documents. The said lever arms are made of a single piece of
wire bent to proper shape, the portion between the parts forming the arms being
mounted so as to turn in sockets or bearings which can be formed by being cut
and bent from the base. The part of the wire between these two sockets or
bearings is so curved as to come into contact with a spring nose so shaped as to
retain the lever arms in either of their two extreme positions, that is, either
open or closed.
The said nose consists of a curved piece of sheet metal, the outer extremities of
which enter an opening in a vertical piece secured to the base as to be capable
of turning in this opening, around its longitudinal axis.
.
A pin bears against the open rear part of the nose and is held in this position
by means of a spiral spring the two ends of which are bent and engaged in
holes in lugs (which may be cut and bent out of the said piece
secured to the base) thus forming pivots on which the pin and nose
turn as an axis. The pin actuated by the spring tends to retain
the nose in position to retain the lever arms in the position in which they
meet the uprights or vertical tubes or in the position in which the said lever
arms are moved free from the said uprights or vertical tubes. On turning the
lever arms away from the uprights or vertical tubes the curved portion of the
wire between the two arms turns the nose upwards against the action of
the spring until the said curved portion of the wire has reached a point at which
the nose is released and returned to its normal position by the spring. On
turning down the curved lever arms the curved portion of the wire moves the
nose downward until the said curved portion of the wire has descended so far
that the nose is again returned by the spring. Thus the nose holds the lever
arms in either of their extreme positions.
A catch or stop prevents the curved lever arms from being over-turned rear-
wardly.

I, MAX KELLER, of 15, Grosser Kornmarkt, Frankfurt on Main, in the Empire
of Germany, Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention has for its object to provide a file for holding papers and
documents together, which file is more durable and simple in construction and
more easily manipulated than are files as hitherto made.
I will describe my invention with reference to the accompanying drawings of
which Figures 1, 2 and 3 represent respectively a rear elevation, a side elevation
and a plan of a file constructed according to my invention. Figures 4 and 5
show the moveable arm of the file in two different positions.
The file has two upright or vertical arms or tubes a rivetted or
otherwise secured to a base and two curved moveable lever armis C
which can be turned in one
direction SO as to meet the upright
or vertical arms 01' tubes " for holding papers or documents in
place or in the other direction so as to leave the arms or tubes a for the removal
of the papers or documents. The lever arms C are made of a single piece of
wire bent to proper shape, the portion d between the parts forming the arms
being fitted so as to turn in two sockets or bearings which can be formed by
being cut and bent from the base b. The part d of the wire between these two
sockets or bearings is so curved as to come into contact with a spring nose e
so shaped as to retain the lever arms C in either of their two extreme positions
that is either closed as shewn by full lines in Figure 2 or open as shewn by
dotted lines in Figure 2 and in full lines in Figure 4.
The nose e consists of a curved piece of sheet metal the outer extremities of
which enter openings in a vertical piece of secured to the base so as to be
capable of turning in these openings around its longitudinal axis. A pin g
bears against the open rear of the nose e and is held in this position by means
of a spiral spring the two ends of which are bent and engage in holes in lugs i
which may be cut and bent out of the piece of thus forming pivots on which the
nose e together with the pin g turn. The pin y actuated by the spring h tends
to retain the nose e in the position shewn in Figure 2 to retain the lever arms C
in the position in which they meet the upright or vertical arms or tubes a or in
the position in which the said lever arms C are moved free from arms or tubes a.
On turning the lever arms C away from the upright or vertical tubes a into the
position shewn in Figure 4 the portion d of the wire between the two arms C
presses upwards the nose e against the pressure of the spring until the said
portion of the wire has reached a point at which the nose is released, which
nose is then returned to its normal position by the said spring h. On turning
down the curved lever arms C in the direction of the arrow in Figure 5 the
curved portion d of the wire moves the nose e downward until the said portion d
of the wire has descended so far as to be free of the nose e whereupon the said
nose is again returned to its normal position by the spring h. Thus the nose e
holds the lever arms C in either of their extreme positions to which they are
moved.
Catches or stops prevent the curved lever arms C from being over-turned
rearwardly.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a file for holding papers and documents, the combination with fixed
upright rods or tubes, of curved arms connected together and capable of being
turned in bearings towards and from the upright rods or tubes; a projection on
a part which connect together the curved arms; a movable piece or nose (e) on
which the said projection acts, to shift the position of the said nose when the
curved arms are moved from one position to another, and a spring arranged to
act on the nose (c) to normally maintain the curved arms in the position to
which they are moved, substantially as hereinbefore described.
2. In a file for holding papers and documents the combination with the upright
rods or tubes a and the hinged curved arms C and the bent connecting part d,
of the nose or piece e made of sheet metal bent to the required shape, and fitted.
to move in openings in a plate f projecting from the base b; a rod or pin g
surrounded by a helical spring h, the two ends of which enter holes in lugs (2)
projecting from the plate f, the said spring pressing the rod g against the nose
(e) so as to retain the said nose in the position to which it is moved by the
movement of the curved arms C, substantially as hereinbefore described.
3. The construction, combination and arrangement of parts constituting the
improved file for holding papers and documents substantially as herein before
described and illustrated by the accompanying drawings.
