2 claims. (c1. 24-259) This invention relates to improvements in clips for temporarily bindingtogether sheets of paper, fabric, and similar material, and in its more specific aspects to clips of the type known as paper clips.

The invention contemplates and has for'v its principal object the provision of an improved paper clip which is simple in handling, easy to apply to the sheets to be bound, and which is so formed that it is capable of binding the sheets flat and tying them together Without bulking, and which, moreover, is sufciently thin as to take up little space in folders or ling cabinets.

It is a further aim of the invention to provide a clip characterized as above which may be readily manufactured in quantity in a single stroke stamping-out process from readily available sheet materials, and particularly from nonmetallic materials, such as vulcanized fiber.

Other objects will be in part obvious and in part hereinafter pointed out in connection with the following analysis of the invention wherein is illustrated an embodiment of the invention in detail.

In the drawing illustrating one embodiment of the invention- Fig. 1 is a plan view of the clip in accordance with the invention;

Fig. 2 is a perspective view of the clip illustrated in Fig. 1 applied as a binder to a p lurality of sheets, such as paper sheets; and

Fig. 3 is a section taken along line 3--3 of Fig. 2.

Referring now to the drawing, wherein like characters designate like parts throughout the several views, a clip according to the invention is preferably stamped out in a single operation from a sheet of suitable material to have form and area providing adequate frictional and binding contact with the paper or like sheets to be bound together. As shown, the clip comprises a body I of generally heart-shaped contour as dened by the outer arcuate edge 2, with a transverse bridging part 3 at its top, the body enclosing a depending tongue cut from the sheet forming the body along an arcuate line of cut 4 which as shown has the same curvature'as that of the outer edge 2, the tongue being 1ntegrally connected with the bridge part 3 by a root 6.

By reference to Figs. 1 and 2, it will be observed that the line of cut 4 between the heartshaped portion of the clip body and the tongue 5 provides only the suflicient clearance required for the adjacent edges of the tongue proper and body part to have relative separating movement, and to come together with a scissoring action on a sheet of paper disposed between the upper face of the clip body and the under face of the tongue. As distinguished therefrom, the side edges of the tongue root 6 are spaced somewhat from the inner edges of the adjacent stay portions H, I2 of the clip bodjn to provide straightway slots 1,. 8 of narrow width to the sides of the tongue root. These narrow slots l. 8 facilitate the insertion of the paper sheets between the tongue root and the stay portions of the clip body, permit the paper sheets to bend readily and freely across the rear face of the tongue root as indicated in Fig. 3, and moreover provide that the tongue can lie at and substantially in the plane of the clip body.

As will be observed from Fig. 2, the clip of the invention is readily applied to the sheets of paper or the like to be bound by springing the tongue 5 slightly forwardly of the plane of the clip body and thereupon slipping the edge portions of the paper sheets into the space between the tongue and clip body until their edges strike the end of the slots l, 8. By reason of the inherent resiliency of the material from Which the clip is formed, the tongue tends to return to the plane of the clip body, and in so doing the paper sheets along their edges are bent at right angles to their planes, and rearwardly of the tongue root, in the manner indicated in Fig. 3. Moreover, the return movement of the tongue results in its edge having what may be termed scissoring action with the inner edge of the clip body, to the end that the paper sheets are gripped between said edges. Due to the arcuate contour of the tongue and the inner edge of the clip body, a relatively long length of gripping edge is provided. Moreover, the large area of tongue face and the equivalently large face area of the clip body present surfaces which have frictional contact on the outer faces of the sheets to be bound, this latter augmenting the scissoring gripping eiect as aforesaid. d

To further increase the gripping effect of the clip, the clip body along its lower inner edge is provided with a point-like projection I3 adaped to fit into a notch I4 cut into the edge of the tongue 5. As shown, the projection I3 and notch I4 are arranged on the longitudinal center line of the clip, it being understood, however, that such positioning 1s illustrative only and that more than one projection and its mating elastic, readily machinable, and possessing the.

property of maintaining its form and resiliency' under varying conditions of use and climate.

As many changes could be madevin carrying out the above constructions-withouttdepartingf, from the scope of the invention, it'isintended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in,.a,limitf ing sense.
