PAPER-BINDING CLIFF.

Application filed March 7, 1921. Serial No. 450,321.

To all whom it may concern:

Be it known that I, EMORY S. ENSIGN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Paper-Binding Clips, of which the following is a specification.

The present invention relates to paper clips of the type in which a sheet metal body-member, developing its grip through its inherent resiliency, is provided with handles for prying it open, articulated with the body-member in a manner to permit them to either swing backward into manipulating position or fold forward to avoid inconvenience in handling the gripped papers, and held in either of these positions by resilient action of a portion of the body-member.

The object of the invention is to provide an improved construction of such clip, and one that is cheaper to produce, more convenient in use, and smaller in overall dimensions than clips of equal capacity as heretofore made.

Accordingly, the invention consists in providing a rigid handle, preferably stamped from sheet metal, with relatively immovable trunnions, presented oppositely therefrom, fashioning the opposed walls of the bodymember to provide bearings in which said trunnions may turn, and stamping from portions of said walls, between their trunnionbearings and in position to bear beneath the handles, longitudinally extending spring tongues, integral with the body at one end but free at their other ends, so that the tongues press the handles into the-bearings and yieldingly resist swinging movement of the handles by their resiliency. The bear ings are open on their inner sides and the body-member is slotted transversely and parallel with but just beyond the bearings to admit the trunnion ends of the handles to the bearings and permit the ready removal of the handles if desired.

In the accompanying drawing- Figure 1 is a plan view of clip constructed in accordance with the invention.

Figure 2 is a longitudinal section of the same with the handles in edge elevation, and in operating position.

Figure 3 is a similar view with the handles in folded position.

Figure l is a view showing the coaction between a handle and a spring tongue; and

Figure 5 is a view of the body member without the handles.

A represents the body portion which is formed of spring sheet metal bent to form the flexible back A and the jaws A The body is stamped to provide in each jaw, alined transverse corrugations b affording trunnion-bearings, and a flexible tongue 0 lying between the bearings of the jaw, with one end integral with the aw at 0 and the other end 0 free. Beyond the bearings b, the jaw has a transverse slot (Z that affords access to the bearings from the outside.

E represents the hand es of flat rigid metal stamped to provide shank portions 7, fitting between the bearings and overlying the spring tongues o and trunnions 9 that enter the bearings and are held therein by said tongues. Trunnions 9 gain access to the bearings through the transverse slots (Z.

The dimension of a handle in the direction of its longitudinal axis between the end against which the tongue bears and the upper edges of the trunnions which impinge against the inner faces of the bearings, is greater than the thickness of the handle at its trunnion end, so that when the handle swings from a longitudinal position toward an upstanding position, such as shown at the right hand side of Figure 4;, there is a very material deflection of the tongue 0; hence the tongue resists such swinging movement of the handle and yieldingly holds it in either of its two longitudinal positions.

To insert the handle, its trunnion end is introduced into the transverse slot 03 and swung forward to the position shown at the right hand side of Figure 3, and the handle is then drawn forward and at the same time has its trunnion end pressed inward until the trunnions enter beneath the rear edges of the trunnion bearings b. To remove the handles, it is merely necessary to force them rearwardly while extended me either forwardly or rearwardly.

I claim:

1. A paper binding clip comprising a resilient body portion having jaws and spreading handles trunnioned thereon; said body portion being constructed with alined transverse bearings and aresilient tongue stamped from the metal therebetween; and a handle being adapted to lie between the bearings trunnions entering said bearings.

2. A paper binding clip comprising a resilient body portion having aws and spreading handles trunnioned thereon; said body portion being constructed with alined trans- -verse bearings an a resilient tongue stamped from the metal therebetween; and a handle being adapted to lie between the bearings and over the tongue and having trunnions entering said bearings; and said body portion having a transverse slot beyond its bearings having a length adapted to admit the trunnions to the bearings from the inner side of the jaw by movement transverse to the axis of the trunnions.

3. A paper binding clip comprising a re silient body portion having jaws constructed with alined transversely extending bearings and a resilient tongue of a width adapting it to Work between said bearings, and handles trunnioned on said body portion a haildle comprising a stamped metal plate having rigidly related trunnions projecting oppositely therefrom into said bearings and lying upon said spring tongue in between said bearings, the trunnioned end of a handle being of greater dimension longitudinally of the handle than through the thicknessthereof. 1

Signed at Chicago, Illinois, this 2nd day of March, 1921.
