SPECIFICATION forming part of Letters Patent No. 516,525, dated March 13, 1894.

Application filed June 17, 1890. f

To all whom it may concern:

Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at'Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Paper-Files, of which the following is a specification.

The objectof this invention is a paper file which shall operate automatically and certainly to open and hold open the file arches so that papers may be readily filed and removed, and which shall be economical of construction and easily operated.

The invention consists in providing the double arches of an ordinary letter file with movable spring supported sections, completing the arches to the base, which sections are movable. together or separately so that both arches of the file-will be opened and closed at the same time or at different times as may be desired and which when moved downward to open the file will be automatically caught and held open. Preferably each of the movable sections is a tube slipped over a pin rising from the base, a spring being arranged to be compressed by the tubes, preferably being coiled around the pin between the bottom of the tube and the base, both sections being connected by a cross bar, in the path of which is interposed a loosely pivoted catch, the hooked end of which catches and holds the cross bar down until released by a finger piece, upon which preferably the catch is carried.

In the accompanying drawings forming a part of this specification, Figure l-is a plan view of aletter file embodying my invention. Fig. 2 is an end elevation of the same looking in the direction of the arrow Fig. 1 showing the arches closed. Fig. 3 is aside elevation with certain of the parts in section on the line 3-3 of Fig. 1 showing the arches opened and the movable sections held by their catch; and Fig. 4 is a view showing certain of the parts in section the view being taken on the plane of the line 44 of Fig. 1.

a in the drawings is the base board of the paper file to which is secured the baseb of the file proper.

c, c, are double arches secured by set screws d, d in nipples e, e cast or formed on the base I). These arches may be of wire bent to the Serial No. 355,708. (No model.)

desired form with the leg of the arch secured in nipple d, longer than the other leg, the.

down to the base I); at its lower end each of the movable sections g is provided with aflange h which rests upon a spring '5 coiled about apin j which projects into the section 9 as shown in Fig. 4. Connecting the two movable sections g is a Cross bar k which is adapted to rest loosely upon the flanges h. It will be seen that by this arrangement it is possible to expose both of the filing points f for the purpose of filing orremoving papers on the arches c by a single movement downward of the cross bar 7a which it the movable sections g.

Arranged in the path of movement of the cross bar It is a catch 1, the hooked endof which is adapted to project over the top of the bar It and hold it in its downward position, while the file is being used to place or remove papers. This catch lis carried on an angular piece of metal or other suitable material, one arm m of which serves as the finger piece for releasing the catch, and the other arm n of which carries the catch itself and is .pivoted to the base b. This arm n as will be seen from an examination of the drawings is bent upward somewhat in front of the catch near the pivot hole 0. This pivot hole is larger than the pivotso that the catch has a loose movement not only from its manner of pivoting but also from its slightly turned up arm n. I have found that by providing a catch of the character shown the action of locking the crossbar is automatically and certainly performed and that no matter what amount of wear the attrition of the cross bar and catch may cause in use, the catch will fol-.

presses before tion returned by pressure of the springs .to

arch, each of said sections being actuated by an independent spring a cross-piece loosely connecting said movable sections, and a catch in the path of said cross-piece, substantially as set forth.

2. The combination, in a double arch paper file of fixed arches, a movable section for each arch, each of said sections being actuated by an independent spring a cross-piece loosely :0 connecting said movable sections, and acatch in the path of said cross-piece loosely pivoted by a pivot-hole larger than its pivot and provided with a turned-up arm, substantially as set forth.

This specification signed and witnessed this 5 14th day of June, 1890.
