HAIRPIN Filed March 14, 1944 Patented Nov. 6, 1945 UNITED STATES PATENT OFFICE HAIRPIN Clara Olive Bergstrom, Portland, Oreg.

Applicativi! March 14, 1944, serial No. 526,881

2 Claims.

This invention relates generally to the art of hair dressing, and particularly to an improved form of hairpin.

The main object of this invention is to provide an exceedingly simple and el'icient means for preventing the loss or accidental dislodgement of hairpins after they are once placed in position in the hair.

The second object is to provide a hairpin of the class described which will be inexpensive to manufacture, easy to apply and remove, and not injurious to the hair or uncomfortable to thek wearer.

These and other objects will become more apparent from the specication following as illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation of a hairpin equipped with my improvement.

Fig. 2 is an enlarged fragmentary View showing a side elevation of the preferred form of the device.

Fig. 3 is a section taken along the line 3 3 in Fig. 2.

Fig. 4 is a view similar to Fig. 2 showing how the barb lies down when a pull is exerted against the pin greater than the force required to insert it.

Fig. 5 is a fragmentary View showing a modified form of the device.

Fig. 6 is a transverse section taken along the line 6 6 in Fig. 5.

Similar numbers refer to throughout the several views.

Referring in detail to the drawing, there is shown a common form of hairpin'll) whose side `members II may or may not be waved, as is the common practice. My improvement on the commonly used existing type of .pin consists of a flexible barb I2, which is preferably natural or synthetic rubber and a part of a tubular section I3 and inclined with relation thereto, it being similar parts desirable to have the base I4 of the barb I2 somewhat removed from the end I5 of the tubular section I3 in order to provide a hair engaging socket I6, and prevent the hair from being caught in the above junction of the members II and I3. The tubular section I3 is either vulcanized to the member I I or frictionally held thereon. In the form of the device shown in Figs. 5 and 6 a strip of rubber or flexible material I'I is formed into the shape of a U, Whose sides I8 and I9 are inclined with relation to the hairpin 20., It is desirable to coat the side members 2I with an adhesive 22 for the purpose of positoning the members I8 and I9 and again for the purpose of preventing hair from becoming caught in the acute angle between members I9 and 2 I.

While only one barb is illustrated in use on a single pin, it is obvious that more can be employed if desired without departing from the spirit of this invention.

While I have thus illustrated and described my invention, it is not my intention to be limited to the precise form shown herein but I do intend to cover all such forms and modications thereof as fall fairly within the appended claims.

What I claim as new and desire to protect by Letters Patent is:

l. A rubber barb for hairpins consisting of a perforated body having a laterally extending barbed portion inclined with relation to the axis of the perforation in the barb.

2. The combination of a barrel shaped rubber body having a cylindrical opening formed therethrough along the axis of the body, a U-shaped hairpin having one of its legs projecting through said body and a flexible barb projecting from one side of said body and pointing toward the closed end of said pin, said barb forming an acute angle with relation to the closed end of said pin.
