JOHN B. CLOPTON, OF BASTROP, TEXAS, ASSIGNOR OF ONE-HALF TO ALBERT
C. ERHARD, OF SAME PLACE.
PAPER-FILE.
SPECIFICATION forming part of Letters Patent No. 457,771, dated August 18, 1891.
Application filed April 30, 1891, Serial No. 391,114. (No model.)To all whom it may concern:
Be it known that I, JOHN B. CLOPTON, a
citizen of the United States, residing at Bas-
trop, in the county of Bastrop and State of
5 Texas, have invented certain new and use-
ful Improvements in Paper-Files; and I do
hereby declare the following to be a full, clear,
and exact description of the invention, such as
will enable others skilled in the art to which
to it appertains to make and use the same.
My invention relates to a paper-file, its ob-
jects being to produce a device for this pur-
pose which will be simple, effective, and du-
rable, as it is composed of few parts, which
f5 can be manufactured so cheaply that it can
be sold at a price which will enable it to be
universally used, and which can accommodate
papers of any width.
To these ends my invention consists in cer-
20 tain features of construction and combina-
tions of parts to be hereinafter described, and
then particularly pointed out in the claims.
In the accompanying drawings, Figure 1lis
a plan view of my paper-file. Fig. 2 is a side
25 view showing the parts in position for hold-
ing the papers, documents, bills, or prescrip-
tions. Fig. 3 is a side view showing the parts
in position for receiving papers. Fig. 4 is a
side view showing the parts in position for
30 removing papers. Fig. 5 is a front elevation
of the latter.
a is the base of the file, which at its upper
end is provided with a transverse bar b, se-
cured thereto in any suitable way and pro-
35 vided with rounded or other shaped end pro-
jections b'. The clamp - frame for holding
the papers c in the file is made of spring-
wire, which is bent into U shape, having a
jaw or front rod d, rearwardly-extending par-
40 allel side arms d' d', springs e e, which are
coiled around the end projections b', and
downwardly-extending ends e' e', which are
let into holes ff in the base just in front of
the bar b, so as to form a fixed connection.
45 The front end of the clamp is bent down-
wardly, so that the jaw d will be brought
firmly against the papers by the springs e e.
g is a presser-foot bent up from sheet metal
into Z shape substantially, and arranged just
5o to the rear of the jaw d.From each side of the upper part of the
presser-foot g extend parallel arms h h, which
at their rear ends are provided with lateral
extensions h' h', which are received by shal-
low recesses i i in the upper sides of the arms 55
d' d', in which the extensions turn slightly.
Coiled around the extensions h' h' are spiral
springs j j, the ends k k of which are hooked
under the arms h h, and the ends k' k' of
which are secured to the arms d' d', thus 60
forming a spring-hinge connection between
the arms of the presser-foot and the arms of
the clamp. In a bearing 1, provided in the
upper bend of the Z-shaped presser-foot, is
journaled a shaft or lifting-rod m, provided 65
at each end with cranked portions m' rm' and
with a crank-handle n, which extends in a
direction at right angles to the plane of the
shaft and its cranked portions.
Hinged on a pivot-rod o, secured in the base 70
a, slightly to the rear of the lower or opera-
tive end of the presser-foot, is a support or
flap p.
r is a hole in the base for hanging the file
on a nail. 75
My paper-file is used as follows: When the
file contains papers, they are held in position
by the jaw d of the clamp, which is pressed
against them by means of the springs e e.
(See Fig. 2.) To inserta paper, raise the han- 80
dle n and pull it forward into the position
shown in Fig. 3 until the handle is parallel
with the base, thus lowering the presser-foot
g onto the papers, if any are in place, and
raising the jaw d of the clamp off the papers 65
by reason of the cranked portions of the
shaft m bearing upwardly upon the arms d'
d'. Now place the paper under the jaw d,
with its upper end against the upright part
of the presser-foot, and hold it in this posi- 90
tion with one hand, using the other hand to
raise the handle n. When the handle is
raised, the action of the springs jj will throw
the handle back and raise the presser-foot
and the parts will be in the position shown 95
in Fig. 2.
To remove the papers from the file, raise
the support or flap p to upright position, so
as to engage under the top part of the Z-
shaped presser-foot and under the arms h ih ro
