7 Claims. (Cl. 132-50) This invention relates to clamps and comprises a new and improved clip, particularly suited for setting the hair and holding waves in place.

The primary object of my invention is to simplify the construction of hairpins and clips, and thus reduce the cost of manufacture of these items.

Another important object of my invention is to eliminate scrapping problems in the manufacture of clips and hairpins.

Each of the embodiments of my invention, described in the following detailed description, are formed from a single sheet of material. Initially, the clip or pin is stamped from the sheet and at the same time the dye forms a number of slits in the blank which define manipulating ears used to open the clip. After stamping, the blank is folded transversely across its center so that onehalf of the stamping overlies the other half. Next, the ears defined by the slits are bent out of the plane of each half of the clip and extend outwardly and away from the ends of the stamping. The transverse fold serves as a hinge for each half of the slip and by squeezing the ears together the two halves of the clips separate about the fold. Normally each half of the clip lies in substantially parallel planes.

Each end of the stamping comprises one or more tines which serve as gripping members. Clips formed with single tines at each end may be used as hairpins, while double-timed clips are better suited for the setting of the hair. It will be apparent from the following detailed description, however, that my invention may be incorporated into many other forms of clamping devices. That is, although the illustrated embodiments are particularly suited for use in the hair-dressing art, they may be used in many diverse fields.

My invention will be better understood and appreciated from the following detailed description of a number of embodiments thereof, selected for purposes of illustration and shown in the accompanying drawing in which:

The narrow strip of material 20 illustrated in Figure 1 has a number of lines on its surface which represent cuts in the stock. These cuts divide the stock into two complete and independent clamps 22 and 24. The cuts 26 and 28 in Figure l define the outline of the clip blank 22 while the cuts 28 and 3t define the outline of the pin 24.

The clip blank 22 defined by the cuts 26 and 28 is shown fully formed in Figure 2. Extending transversely across the center of the clip blank 22 are a pair of cuts 32 and 34 which extend inwardly from the sides of the stamping to a pair of coextensive longitudinal slits 36 and 38. As suggested in the introduction of this specification, the slits 32, 34, 36 and 38 may be introduced into the material during the initial stamping operation.

After the blank is formed, it is folded in half along the slits 32 and 34, and the portions of the blank defined by the slits are bent outwardly and away from the ends of the stamping as suggested in Figures 2 and 3. In this manner, manipulating ears 44-, 46, 33 and 5t? are formed in the clip to facilitate opening.

As shown in Figure 2, the cut 26 defines a pair of tines 4t and 42 at one end of the blank which overlie similar tines 52 and 54 formed by the cut 23 at the opposite end of the blank. These tines normally lie in parallel planes and may be spread about the fold which is contiguous with the slits 32 and 34 by squeezing the manipulating ears 44, 46, 48 and 5% together. Thus, it is seen that the fold serves as a hinge for the clip. Obviously, if the material used to form the blank is resilient, when the manipulating ears are released, the tines and 42 formed in one-half of the stamping will assume their normal position adjacent the tines 52 and 54 formed in the other half of the device.

The pin 2 shown in blank form in Figure 1 is formed in a manner identical to that described for the clip 22. The pin 24 difiers from the clip only in that it has but one tine on each end to serve as a gripping member.

The manner in which scrapping is eliminated is clearly illustrated in Figure l. The cut 28 which separates the clip 22 from the pin 24 forms double tines at one end of the clip 22 and a single tine at the adjacent end of the pin 24. This overlapping pattern utilizes all of the stock, thus no waste material results.

The pin blank shown in Figure 4 is very similar to the pin blank 24. It too may be mass produced without a scrapping problem by alternatively stamping a pin and a clip. It will be noted that coextensive longitudinal slits 56 and 53 are cut in the central portion 66 of the blank and a transverse slit 62 coincident with a fold line 64 interconnects the centers of the longitudinal slits. The longitudinal and transverse slits 56, 53, and 62 define manipulating cars 66 and 68. After the blank is formed by cutting along lines 62 and 71, it is folded over along the line 64 and the ears 66 and 63 are bent out of the planes of the halves of the blank to the position illustrated in Figure 6. To separate the tines "i0 and 72 defined by the cuts se and 71, the ears 66 and 68 are pressed together. When the ears are released, the tines return to the closed or biased position.

Figures 7 and 8 illustrate still another embodiment of pin. The central portion 7 3 of the stamping illustrated in Figure 7 is folded along line 76 which extends transversely across its center. Adjacent the fold line 76 are two pairs of longitudinal slits 78 which are joined at their outer ends by transverse slits 80. The slits 78 and 8G in each half of the blank define ears 82 which are folded over and out of the planes of each of the halves of the blank in the manner shown in extend outwardly and away from the ends of the clip so that pressure exerted on them will open the pin above the foldline76. The blank shown in Figure 9 contains the slits 78 just as the pin of the preceding embodiment. However, these slits are joined by transverse slits 84 at their inner ends rather than at their outer ends as in the preceding embodiment. The slits '78 and 84 define manipulating ears 86 which are bent out from the plane of the halves of the pin in a manner identical to the ears 6t: and 6% described above. Once again, pressure exerted on these cars will spread the pin about the fold line 7 6.

' It will be apparent from the foregoing description that each of the configurations f the manipulating ears may be used with either one or two or any number of tines as gripping members. Moreover, although the manipulating ears have been described in the environment of a hairclip or pin, they may be used in many other forms of clamping devices. For example, tweezers or tie pins may take the form of the clamps described above. In Figure 11, I have illustrated a clampmg device very similar to that shown in, Figure 3 but particularly designed to serve as an eyelash holder. A slight curvature hasbeen introduced into the tines and they are somewhat elongated. Preferably such a device would be formed with single tines at each end.
