PAPER-FASTENEB.

Specification of Letters Patent.

Patented Nov. 15, 1921.

Application filed latch 24, 1820. Serial No. 368,342.

This invention relates to paper fasteners of that type com rising a U-shaped member, the arms of whic are adapted to be inserted through the papers to be fastened together, and a retaining member havlng apertures through which the ends of the arms pr0 ect, the projectin ends of the arms being adapted to be fol ed down against the retaining member thereby to hold the retaining member in position.

The invention relates particularly to a novel construction by which the bent-over ends of the arms are retained in their locking position. Thisis accomplished in the present invention by means of a keeper which is detachable from the retaining member and which when in operative position overlies the bent-over ends of the arms, thus retaining them in such position.

In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claim.

In the drawings, Figure 1 is a side view of a device embodying my invention showing the retaining member in place but the keeper removed 5 Fig. 2 1s a similar view showing the keeper in place retaining the bent-over ends of the arms against the retaining member;

Fig. 3 is a section on the line 3-3, Fig. 2;

Fig. 4 is a perspective view of the device.

As stated above, mfy invention relates to that type of paper astener comprising a U-shaped body member 1 having the two arms 2 that are adapted to be inserted through the papers 3 to be fastened together, and a retainlng member 4 which is provided with apertures 5 adaptedto receive the ends of the arms 2 that project through the paper, said arms being bent over against the retaining member to hold the retaining member in position.

In the present construction the retaining member 4 is formed with a recess or depression 6 extending from one aperture 5 to the other, said depression being of a width and depth sufficient to receive the bent-over portions of the arms 2.

In using the device'the arms 2 areinserted through the papers 3 and then the retaining member. 4 is applied, as shown in Figs. 1 and 4, and when the retaining member is pressed down firmly against the papers 3, the ends of the arms 2 which roject beyond the retaining member are ent over into the recess 6, as shown by dotted lines Fi 4.

I In (mi r that the device may be effective in retaining the papers together, it is, of course, essential that the bent-over portions of the arms 2 should be held in thelr bent-over position. Otherwise they are likely to be pulled out from the retaining member. I provide for thus holding the bent-over portions of the arms 2 in their bent-over position by means of a keeper 7 which is detachably secured to the retaining member 4. This keeper is in the form of'a plate which when secured to the retaining member will overlie the bent-over portions of the arms. The keeper may be detachably secured to the retaining member in various ways. One simple way is to make the keeper with the inwardly-turned lips 8 at its edges so that it can be slid over the retaining member 4 with the edges 8 of the keeper embracing the edges of the retaining member. When the projecting ends of the arms 2 are bent over into the recess 6, the bent-over ortions of the arms come'substantially flus with the top of the retaining member so that thekeeper can be readily slipped onto the retaining member from one end. When the keeper is in the position shown in Figs. 2 and 3, it overlies the bent-over portions of the arms 2 and firmly holds them in their operative bent-over position.

The operation of removing the device from the papers involves ing the keeper 7 and then straightening the bent-over portions of the arms 2 to permit the keeper to be withdrawn.

The construction of the retaining member 4 is advantageous because the depressed portion 6 constitutes the part of the retaining member which engages the stack of papers 3 and therefore when said retaining member is pressed firmly against thepapers the edges thereof will be separated from the papers by a distance equal to the depth of the depression 6 so that there is space between the edges of the retaining member and the papers to permit the keeper to be readily applied while the papers are clamped firmly together.

I claim:

A paper fastening comprising a body having integral therewith two arms extending laterally therefrom and adapted to be inserted through the papers to be fastened together, a retaining member having apertures through which the projecting ends of said arms extend, said arms being constructed to be bent over against the retaining member and the latter having the portion between the apertures oifset below the body of the keeper thereby to provide a depression to receive the bent over ends of the arms and also spacing the edges of the retaining member from the papers, and a keeper in the form of a plate having its edges bent over to form lips and adapted to embrace the retaining member.

In testimony whereof, I have signed my name to this s ecification.
