Application filed February 10, 1922. Serial No. 585,508.

To afl whom it may concern Be it known that I, LOUIS ELZE'AR How, a British subject, residing at 544 Chambord Street, in the city of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Paper Clips; and I do hereby declare that the following is a true, clear, and exact description of the same. I

The present invention relates to improvements in paper clips, fully described in the following description and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of the invention.

Figure 2 is an elevation of the back of the device.

Figure 3 is a front View of a modified form of the invention.

Figure 4 is a cross section view on line 4-4 of Figure 3.

Figure 5 is a side elevation view.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings:

1 is a base plate preferably of rectangular shape having at one end thereof the upturned edge 2, and centrally between and parallel with its side edges the elongated depression 3, projecting from adjacent the upturned edge 2 and extending past the center of said base plate. Between the end of said elongated depression 3 and the lower edge of said base plate 1, on opposite sides of said depression, the base plate is punched or slit, as indicated at 1, to produce two lateral tongues which are folded over each other or overlapped at the back of said base plate to form the guiding bracket or bridge 5.

The longitudinal depression or channel 3 is pressed or stamped out from the base plate in such a way as to produce an opening at its inner end 9; and said open end 9 is disposed in line with the bridge 5. 6 is the gripping element consisting of a wire of any suitable metal preferably of rectangular shape, and slightly larger than the base plate 1, the free ends 7 of said wire being bent inwardly at right angles in relation to the sides of said wire and curved at 8 so as to lie fiat in said channel or depression 3, said free ends 7 projecting through the open end 9 of said channel 3 and engaging in the guiding bridge or bracket 5. The gripping element 6 is limited in its movement in one direction by the upturned edge 2, and in the other direction by the edge of the open end 9 of the depression or channel 3.

In the operation of the present invention it is preferable to slightly pull out the gripping element to the dotted line position illustrated in Figure 1. The papers to be secured by said clip are introduced in between the rectangular gripping element 6 and the said base plate 1, as is done with clips of this character. By pressing the clip over the edge of the papers the gripping element 6 will be pushed upwardly against the edge 2 simultaneously with the papers, thus providing a firm grip even if the thickness of the papers is relatively great, the wire sides of the gripping element 6 being lifted accordingly to provide for the thickness of papers, and sufiicient resilient strength is obtained through the curved portions 8 provided {on the free ends 7 of said wire.

In a modified form of the invention disclosed in Figures 3 and 4 a longitudinal slot 9 is formed centrally in said channel 3. At opposite sides of said slot 9 the free ends 7 of the gripping element 6 are situated. Across said free ends 7 extends a strip 10 which is held in place in said channel 3 by means of the rivet 11 which projects through said slot 9 and is provided with the head 12. The object of the strip 10, which is longitudinally slidable in said channel 3 is to prevent the free ends 7 of the gripping element .6, when a relatively great thickness of papers is inserted between said base plate and gripping element, from lifting out from said channel 3. The said strip 10 will be carried to the upper'end of the slot 9 adjacent the curved edge 2 simultaneously with the gripping element by the friction of the documents when the clip, is slipped thereon.

What I claim as my invention is:

l. A paper clip, consisting of a self-complete unit comprising a base plate; a gripping member having a tendency to lie flat against the base plate and permanently connected to the same to slide longitudinally forward and backward thereon; and means on the base plate for limiting both move ments of said member.

2. A paper clip, comprising a base plate ping member having portion thereof slidably disoosed in said channel and projecting beyond the same into eng ement with said guide, whereby the pping member will be held in place against the base plate while capable of a bodily longitudinal movement thereon in either direction.

3. A paper clip. comprising a base plate provided with a longitudinal channel and with a guide in line therewith; and a spring wire gripping member having parallel inturned ends slidably disposed in said channel and projecting beyond the same into en agement with said guide. whereby the ipping member will be held in place against the base plate while capable ot a bodily longitudinal morenient thereon in either direction.

4-. A paper clip, comprising a base plate provided with a channel; a gripping member, between which and the base plate the paper to be held is interposed; said member having a tendency to lie flat against said plate so as to clamp the interposed paper against said plate and embodying a portion slidahly disposed in said channel to enable said member to move forward or backward alon the plate; and means for holding said portion in place in the channel during the sliding movements of the gripping member.

either direction.

provided with a channel; a gripping member, between which and the base plate the paper to be held is interposed, adapted to automatically clamp the interposed paper against said late; said member having an integral, resilient portion thereol slidably engaged in said channel to enable a bodily longitudinal movement of said member in either direction, one end of said channel forming stop to limit the movement of said member in one direction; and laterally projecting means on the base plate for li1n iting the movement of said member in the opposite direction.

Signed at Montreal, Quebec, Canada, this 16th day of January, 1922.
