Substituted for abandoned application Serial No. 350,359, April 22, 1953. This application February 14, 1955, Serial No. 487,751

1 Claim. (CI. 24-67) This invention relates to paper-fastening devices, and more particularly to wire paper clips of the type which is adapted to engage the edges of paper sheets laid together, and also to pins which are adapted to be inserted through the surfaces of paper sheets laid together, an object of the invention being to provide an improved paper fastening device which combines, in its construction, the features of both a paper clip and a pin to form a paper pin-clip, as it is hereinafter called. This is a substitute for my application 350,359, abandoned.

Other objects of this invention are to provide a paper pin-clip which: (a) fastens the edges of paper sheets laid together by a combined clipping and stapling action in a manner which prevents a paper sheet from slipping out of position; (b) provides a positive interlock when fastened to the edges of paper sheets so that the clip cannot slip out of position; is especially adapted for fastening flimsy cloth to paper sheets; and (d) is exceedingly simple in construction and provides a low-cost article adapted for a number of other uses.

With the foregoing and other objects in view, all of which more fully hereinafter appear, my invention comprises certain novel constructions, combinations, and arrangements of parts and elements as hereinafter described, and as defined in the appended claim, and illustrated, in preferred embodiment, in the accompanying drawing, in which:

Figure 1 illustrates one form of my improved paper pin-clip.

Figure 2 is a fragmentary perspective view of two sheets of paper fastened together at the edges by the paper pin-clip illustrated at Fig. l, but with the clip shown on a smaller scale and with broken lines indicating parts hidden from View.

Figure 3 is a fragmentary perspective view similar to Fig. 2, but showing the two sheets of paper fastened together at a point inwardly from the edges, and showing a slight modification of the construction of the paper pin-clip illustrated at Fig. 1.

Figure 4 is similar to Fig. l but shows an alternate form of my improved pin-clip.

Figure 5 is similar to Fig. 2, but shows the paper fastened together at the edges by the clip illustrated at Fig. 4. s

The most common devices for fastening paper sheets together include wire paper clips and common pins. The paper clips are formed by a plurality of loops of bent wire as fingers which are adapted to slide over opposite faces of the paper sheets to grip and hold the paper sheets together, while the pins are the conventional straight pointed pins adapted to be inserted through the paper sheets successively at a plurality of points and thereby interlocked with the sheets. Each has certain disadvantages in use. The paper clip has a tendency to become easily loosened and papers will often slip out of the grip of the clip and be lost or misplaced, or the clip itself may drop off the sheets and be lost. When pinned together, the papers will often become loosened or tear,

especially if pinned near the margin. Also the fastening of papers together by pins is unsightly. To overcome these objections, the present invention was conceived and developed, and comprises in essence, a paper pin-clip formed of bent wire having fingers adapted to slide over opposite faces of the paper to grip and hold the sheets together, combined with one or more point-sharpened fingers to provide an insertion through the paper to insure the permanent desired positioning of the unit upon the sheets and positively connect and interlock the sheets together.

Referring to the drawing, and to the construction illustrated at Figs. 1, 2, and 3, my improved pin-clip 10 is formed from a suitable length of wire which is sharpened at the points 11. The wire is bent to provide a symmetrical unit having straight shanks 12 at each side thereof in spaced parallelism, which terminate as the points 11 at one end and as loops 13 at the opposite end. The loops 13 turn inwardly to the center of the unit and extend together to form a tongue 14 which is between, and in spaced parallelism from and coplanar with, the shanks 12. The tongue 14, which is composed of a length of wire bent upon itself, may terminate as a blunt point 15, as shown at Figs. 1 and 2, or may terminate as an eye 15, as at Fig. 3, or any other shape desired.

In use, this pin-clip 10 is engaged to the edges of sheets of paper 16 with the shanks 12 at one side of the paper sheets and tongue 14 at the other side to provide an interlocking action in a manner similar to that of a conventional paper clip. As the shanks 12 are positioned, they are inserted through the paper sheets by piercing as at 17 and thence threaded again through the sheets, as at 18, when nearly positioned, all as clearly illustrated at Fig. 2. So threaded, the paper sheets 16 are securely held together and the clip is secured in position.

Where it is not desirable to mount the paper clip upon the edges of the sheets 16, the ciip 10 may be attached as at Fig. 3, where the shanks 12 are shown threaded through the sheets 16 at a point below the edges of the sheets, as at 17' and 13.

As alternate construction of a pin-clip, 10a, as shown at Fig. 4 and Fig. 5, employs a suitable length of wire having a point 11a, and is formed with a single central shank 12a which terminates as the point 111: at one end, and folds over at the other end to form a side loop 19, thence transversely across the top of the clip as at 20, and thence forms a second side loop 21 opposite the loop 19, but in the same plane therewith. This pin-clip 10a may be mounted upon the edges of sheets of paper 16, as shown at Fig. 5, with the shank 12a at one face of the sheets and the

loops

19 and 21 at the opposite faces, and with the shank 12a threaded through the sheets at 17a and 18a to provide a secure tight fastening.

Alternative and equivalent details of construction which are within the spirit and scope of my invention will occur to those skilled in the art; hence, it is my desire that my protection be limited, not to the details of construction herein illustrated and described, but only by the proper scope of the appended claim.

I claim:

A paper pin-clip comprising a length of wire having a pointed end, and being folded with the wire lying in a flat plane to form a central shank at the pointed end portion of the wire, a loop at one side of the shank with the wire extending to around the end of the shank portion and a second loop at the side opposite the first loop, said loops forming fingered portions at each side of said shank and in the said flat plane.
