DEVICE FOR FILINGLETTEBS AND THE LIKE.

Application filed August 24, 1925, Serial No. 52,157, and in Germany January'25, 1924.

My invention relates to a device for filing letters and the like and especially to a device of this kind with rotatory arched holding-arms held in position against each other by spring pressure, said spring pressure acting upon one holding-arm half while the other half is freely rotatable. In the usual forms of such filing devices the springactuated holding-arms are prevented from hindering the filing or removal of documents as the file lies opened, by some device which keeps them fixed apart during. the operation. It is the object of my present invention to obtain the same result by providing the spring actuated arched wire op posite the freely rotatable arched wire with a stop which restricts the movement of the spring-actuated wire towards the contents of the file. This stop is so positioned in relation to the bottom plate of the device, which bottom acts as an abutment in conjunction with said stop, that thereby the spring effect is not impaired when the two halves of the arched holding wires are closed, that is to say, it ispositioned in such a way that when the filing-device is open the spring-actuated legs are able to yield to some extent under the pressure of the spring. In a further development of the invention this stop is formed by appropriate indentations or lateral archings in the shank which serves as an axis of rotation and interconnects two equally positioned halves of the holder-arms. Below said identations I provide reenforcements of the base-plate,

and I utilize these reenforced places for fixing said base plate to the filing case by means of rivets or the like, whereby I am enabled to make the base-plate of thinner sheet metal, than would otherwise berequired. An example of the application of the invention is illustrated in the drawings. a.

-Fig. 1 shows the filing-device inaccordance with my invention in front elevation and Fig. 2 in plan view.

Fig. 3 shows, in an elevation view similar to Fig. 1, the filing-device in an open position, and the effect of the stop as provided by my present invention, the closed position being indicated by dotted lines and a further position 'of the freely rotatable leg by dash-and-dotted lines.

The two halves a and b of the holder are carried on horizontal shanks 0 and cl, which are secured on the base-plate 9 so that they can oscillate freely in bearings e, e and f, 7 formed by cut-out tongues of the base-plate. The shank (Z with the two legs Z1, Z) can rotate freely, whereas the shank c of the two halves a, e of the holder is under the action of a coiled spring h, which with one end lies against the base-plate g and with the opposite end effects on the ear '5 of the shank c a pressure directed towards the halves b, b of the holding-arms and keeps the legs a, I) closed, when the guide-pegs Z2 b engage for that purpose in the corresponding openings in the halves a, a of the holding-arms.

In the shanks .c of the spring-actuated are provided, which when the halves of the holders are in the position shown in Fig. 1 form an acute angle with the base plate g, and when they are in the position shown in against the base-plate g and thus limit the deflection of the half a of the holder in the halves a, a of the holders, offset portions 7e, 7e

Fig. 3 in full drawn lines he abutment-wise ing through the holes Z rivetsor screws wherewith, to fix said base plate to the filing case.

' The two pegs b and b of the legs 6, b are of different length so that one 6 enters the corresponding hole of the opposite leg a first and thus. serves as guide for the other peg b 7 7 What I claim as my invention and desire to secure by Letters Patent of the United States, is

1. In a filing device, the combination with a base-plate, of two arched rotatable structures engaging each other to form a file holder, a spring acting upon one of said structures in the. direction towards the other structure, and means onsaid spring actuated structure and adapted to maintain said structure in upright position when out of engagement with the opposite structure.

2. In a filing device, the combination with a base-plate, of tWo arched rotatable structures engaging each other to form a file holder, a. spring acting upon one of said structures in the direction towards the other structure, and on said spring actuated struc' ture an ofiset portion adapted to maintain said structure in upright position when the same is' out of engagement With the opposite structure.
