ing pressure.

An important object of my invention is to provide for the employment in such a file or clip of a Cshaped spring which may be applied without any riveting, and 'which is so arranged that it is protected and held in place by the finger-pieces.

Ihe invention will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of a file or clip embodying my invention. Fig. 2 is an end View thereof; and Fig. 3 is a transverse section upon about the plane indicated by the dotted line :0 m, Fig. 1.

Similar letters of reference designate corresponding parts in the severalfigures.

A designates the two jaws or members,

which are, in this example of the invention,

long and of little width, and which are hinged or pivoted together along their longitudinal edges at I). The opposite edges, 1), of the jaws or members Ai'orm their biting or holding portions, and the two jaws or members are concavo-convex in a plane transverse to the axis of the pivot b, which connects them, or are of like form or duplicates each of the other. By this form the jaws or members are given a hearing at their edges only, and they more effectively hold the 'papers inserted between them.

From the hinged edges of the jaws A extend finger-pieces -B, which, as here shown, are made separate from the jaws and secured to them by rivets c, or otherwise. The-parts of the file or clip are stamped or cut out from sheet metal by suitable dies, and when the (No model.)

lingenpieees B are made separate from the jaws or members and secured to them the metal can be cut with less waste or scrap.

G designates a spring,which is C-shaped, as shown bestin Fig. 3, and has its ends 0. hooked, as also shown in' Fig. 3. This spring is ar ranged so as to be shielded and held in place by the finger-pieces B; and in this example of my invention the finger-pieces are formed with slots b, which are of a width sligh tlygreater than the width of the spring 0, and the said spring is arranged within the slots of the two fingerpieces, as shown in Figs. 1 and 3. Extending inward from the opposite walls of the slots b in the finger-pieces B'are spurs or projections b, with which the hooked ends 0 of the spring 0 engage, and the spring therefore exerts its force to close the edges 11 of the jaws or members upon the papers inserted between them. By this construction the spring is held in place and has its ends so connected with the jaws or member that no rivets or other devices are needed to properly secure the spring in place. Through the finger-pieces B B the ends of the spring are connected with the jaws or members.

7 Instead of forming separate projections or spurs b at opposite walls of the slots b the finger-pieces may be formed with the cross bar, as shown by dotted lines, Fig. 1, for the engagement of the hooked end 0 of the spring. It will be observed that the two jaws A are duplicates each of the other, and that the fingerpieccs B are also duplicates each of the other, and the jaws are concavo-convex in their transverse section. Hence both jaws maybe formed with the same dies, and both finger-pieces can also be formed with the same dies. Vhen the jaws are both concavoconvex, their gripping-edges have a better hold upon papers than when one jaw has a 5 gether at one edge and having the slotted booked and applied to close the jaws 0r meinthe j aivs or members, arranged in the slots of hers, substantially as herein set forth. the finger-pieces, substantially as herein set 2.
