SPIRAL BOBBY PIN Filed Dec. 19, 1949 In ventor Ben Adler Patented Sept. 26, 1950 UNITED STATES PATENT OFFlCE 4 Claims.

This invention relates to bobby pins, and more particularly to a bobby pin provided with a longitudinal twist for inducing hair to curl.

The primary object of this invention is to provide a bobby pin which instead of causing the hair to lie fiat against the scalp of the user will cause the hair to curl.

Another important object of this invention is to provide a bobby pin in which the direction of the curl used thereby is determined by the bobby pll'l.

Another important object of this invention is to provide a bobby pin of such structural design as to permit the same to be formed of light weight material and which when in position tends to be self-locking.

A meritorious feature of the present inven-' tion resides in the longitudinal twist provided in the legs of the hair pin whereby the hair is not permitted to lie flat against the scalp and the greatest advantage is realized from the strength of the material.

A final feature to be specifically enumerated herein resides in the broad faces of the legs of the bobby pin being in contact substantially their entire length, whereby a self-locking action is attained.

These, together with various ancillary features and objects of the invention which will later become apparent as the following description proceeds, are attained by the present invention, preferred embodiments of which have been illustrated by way of example only in the accompanying drawings, wherein:

Fig. 1 is a top plan View of a suitable form-of the present invention;

Fig. 2 is a side elevational view of the bobby pin shown in Fig. 1;

Fig. 3 is a top plan view of a modified form of the present invention; and,

Fig. 4 is a side elevational view of the bobby pin shown in Fig. 3, the concealed extremity of one of the legs being shown in dotted outline.

Reference is now made more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, attention being directed first to the form of the invention shown in Figures 1 and 2. As clearly shown in the drawings the bobby pin indicated generally by the numeral i9 is formed from a single strip of resilient material of substantially greater width than thickness. The bobby pin Ill is substantially U-shaped having a loop l2 and legs l4 and Hi. The legs l4 and it have their broad faces in contact substantially their entire length and are twisted together about their longitudinal dimension thru a right angle to a position in which the planes of their outer ends are perpendicular to the planes of the material of loop l2. It will b noted that in the preferred construction the leg I4 is shorter than the leg l6 and has its outer extremity outwardly inclined as at I8.

The embodiment shown in Figs. 3 and 4 is quite similar to that shown in Figs. 1 and 2. The bobby pin 20 shown in Figs. 3 and 4 is provided with

legs

22 and 24 and loop 26, the leg 22 being shorter than leg 24 and being outwardly inclined as at 2B. The latter modification shown in Figs. 3 and 4 difiering primarily from that shown in Figs. 1 and 2 in that the

legs

22 and 24 are twisted together thru an angle of 180 degrees rather than degrees, so that the planes of the outer extremities of the

legs

22 and 24 are parallel to the planes of the material forming loop 26. As in the first modification, the

legs

22 and 24 have their broad faces in contact for substantiall their entire length.

The use of the bobby pin will be readily understood. The longitudinal twist in the bobby pins prevent the hair lying flat against the scalp and cause the same to curl, the bobby pins of the present invention being applied in substantially the same manner as conventional bobby pins. The twist in addition substantially increases the rigidity of the bobby pin and serves to assist in retaining the legs in close proximity of each other; whereby pins of lighter construction may be employed with optimum results. The twist also serves to cause the legs of the bobby pin to engage the hair in a semi-locking manner, whereby the correct position and retention of the same is assured. It will be readily appreciated that the direction in which the hair will curl will be largely dependent upon the direction of twist in the bobby pin, therefore the production of the bobby pins of clockwise and anti-clockwise twist is contemplated, as well as variations in dimensions of the same to accommodate different types of hair.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specifications and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to falling within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A bobby pin formed from a single strip of resilient material substantially greater in width than in thickness, said strip being formed into a substantially U-shape having a loop at one end and legs beyond the loop disposed with their broad faces in contact, said legs being longitudinally twisted intermediate their ends.

2. The combination of claim 1, wherein one of said legs is shorter than the other and has its outer extremity outwardly inclined.

3. A bobby pin formed from a single strip of resilient material substantially greater in width than in thickness, said bobby pin being U-shaped and having a pair of legs, said legs being twisted together through a right angle about their longitudinal dimension, the broad faces of said legs being in contact substantially the entire length of said legs, and the planes of the outer extremof the outer extremities of the legs are parallel to the planes of the material forming the loop, the broad faces of the legs being in contact for substantially their entire length.
