1 Claim. l

This invention relates to bobby pins, and the main object is the provision of a double bobby pin substantially in the form of a attened S, that is, one formed of a unitary length or strip of material having both ends thereof from points spaced approximately one-third of the length of the strip doubled back against opposite sides of the central portion of the strip, both the said end lengths being provided with wave-like corrugations.

Bobby pins in common use are of the general form of a U and hence are prone to slip out of place endwise, whereas the double bobby pin of this invention will not easily slip out of place because it comprises in eiect two opposed U- shaped bobby pins both having one arm of its U in common and because the hair is engaged in both of the Us thereof. Consequently, this double bobby pin will hold the hair permanently.

The double bobby pin of this invention also serves as a curl (wave) fastener and is therefore especially useful in making artificial permanent waves.

The above as well as additional objects will be claried in the following description, wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drowing is intended solely for the purpose of illustration and that it is therefore neither desired nor intended to limit the invention, as disclosed, to any or all of the exact details of construction shown or described except insofar as they may be deemed essential to the invention.

Referring brieily to the drawing, Fig. 1 is a perspective View of the double bobby pin of this invention.

Fig. 2 is a top View of the pin of Fig. l.

Fig. 3 is a side elevational view of the same.

Fig. 4 is a perspective view of a modified form of the double bobby pin.

Referring in detail to the drawing, the numeral IU indicates a complete double bobby pin constructed in accordance with the teaching of this invention, in any desired manner, out of a single strip of resilient material of any suitable kind or type.

The completed pin comprises a mid-portion i I which is positioned between the two end portions I2 and I 3 which are normally urged by the resiliency of the material against and substantially into contact with the mid-portion. The end portions I2 and I3 of the pin are identical except that they extend in opposite directions from the extremities of the mid-portion II.

The bights I4 are formed between the end portions and the mid-portion and are rounded and elongated, substantially as shown, the end portions I2 and I3 being each provided with a series of substantially identical waves or corrugations I5. In the normal position of the several portions of the pin, when not in use, the end portions I2 and I3 are spaced equidistant from each other throughout their length, or, in other words, the crests of the corrugations I5 of one end member are positioned directly under the troughs of the corrugations of the other end member, as is apparent in Figs. 1 and 3.

Fig. 4 shows a modified form of the double bobby pin Illa, wherein the only diierence is that the pin is constructed of a single length of wire instead of a strip as in the form previously described.

It is apparent that when a lock or strand of hair is clamped between the end member I2 and the mid-portion II and another strand of hair is clamped between the other end member I2 and the mid-portion II, the pin will be restrained from slipping longitudinally, which condition does not exist in the case of the cornmon U-shaped bobby pin having one end thereof open so that the pin may slip completely away from the strand of hair.

Obviously, modifications in form or structure may be made without departing from the spirit or scope of the invention.

I claim:

A double bobby pin comprising a unitary length of material of substantially constant cross-sectional dimensions comprising a mid-portion of approximately one-third the length of said unitary length and having the ends each approximately equalling the length of said mid-portion and doubled back against the opposite sides of said mid-portion, said ends having wave-like corrugations formed thereon throughout their length, bights formed at the extremities of said mid-portion by the doubling back of said ends as aforesaid, said bights being rounded, that portion of each of said end portions adjacent one of said bights being straight and extending at an acute angle with respect to said midportion and further having a length'equal at least to the length of two of said corrugations.
