2 Claims.

This invention relates to hairpins or clips and especially that type used upon bobbed hair or the like.

There is a considerable variety of hairpins or clips in use at the present time which are intended or especially constructed for use upon bobbed hair. All of them employ a pair of resilient leg members connected at one end by a loop or eye, the leg members being crimped, corrugated, or otherwise roughened throughout a portion of their length to clip the hair placed between them. Surfaces of this character clip the hair in one direction only; that is, it resists longitudinal removal of the pin from the strands of hair clasped between the legs but these surfaces do not satisfactorily secure the pin against lateral removal,

or in other words from working loose by slipping in a direction longitudinal of the strands of hair and, as such, are not altogether satisfactory.

The object of the present invention is generally to improve the construction and operation of pins of the character described, and more specifically to provide a pin which not only clips against longitudinal removal but also against lateral movement in either direction.

A pin having the above characteristics is shown by way of illustration in the accompanying drawing, in which- Fig. l is a perspective view of the pin;

Fig. 2 is a diagrammatic enlarged plan view of a portion of the pin; and

Fig. 3 is a side elevation of the pin.

Referring to the drawing in detail, and particularly Fig. 1, a hairpin is illustrated which is 3 made of a resilient material, such as spring steel, or the like. This material is cut in suitable lengths and bent midway to form a loop or eye 2 and a pair of leg members 3 and Q, the leg 3 being slightly shorter and bent at its outer end to permit it to be readily opened when the pin is to be applied to the hair.

Wire, which is round in cross section, is employed in the manufacture of the pin. This wire is fed between a pair of rollers to which sufficient pressure is applied to flatten or partially flatten it as it is fed between the rolls. In the present instance portions of the peripheral surfaces of the rollers are indented or slightly relieved at spaced intervals, causing portions of the wire to 50 'be fully flattened and other portions only partially so. The portion, for instance forming the eye 2, is only partially flattened and as such leaves a thickened portion retaining substantially all of the spring action of the wire; this being desirable as the spring action of the wire is largely depended upon to impart clamping action to the legs.

The portions of the legs, indicated at 311 and 4a,, are fully flattened while the portions 312 and 412 between them remain substantially unflattened. These unflattened portions produce a roughened or corrugated surface, see Fig. 3, which secures the pin against lengthwise removal from the hair. The flattened portions 3a and 4a, on the other hand, form widened portions lengthwise of the legs and these widened portions, together with the narrow unflattened portions 3b and 4b form undulations or corrugations in the opposite side edges of the legs, which also tend to resist lengthwise removal of the pin, but in addition produces another function, to-wit, that of securing the pin against lateral movement or in other words movement lengthwise of the strands of hair upon which they are clipped. I

The resistance of the pin against lateral movement can be plainly seen in Fig. 2, in which the lines indicate strands of hair. The flattened or widened portions 3a tend to spread the hair While the narrow portions 31) cause compacting of the hair. This compacting of the hair resists tendency of the pin to move laterally in the direction of arrows at and b, or in other words longitudinally of the strands of hair, and as the corrugations formed by the narrowed portions 3b and 4b resist longitudinal movement of the pin, or in other words crosswise of the hair, an enicient grip between the pin and hair, both longitudinally and laterally, is insured.

While a specific form of the pin is shown, it will be understood that varying changes may be resorted to within the scope of the appended claims. Similarly, while both legs are shown as provided with expanded and narrowed portions throughout a portion of their length, one leg only may be so formed, the important feature being the provision of means on the opposite side edges of the legs of the pin to resist lateral movement.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a hairpin of the character described a pair of resiliently connected leg members, adapted to contact each other, said legs having alternately arranged expanded and narrowed portions throughout a portion of their length to form undulating side edges and said undulations being staggered with relation to each other.

2. In a hairpin of the character described a pair of resiliently connected leg members adapted to contact each other said legs having alternately arranged expanded and narrowed portions throughout a portion of their length to form undulating side edges said undulations being staggered with relation to each other to resist longitudinal movement of the legs upon a strand of hair and corrugations between their contacting faces to grip a strand of hair and resist movement of the legs crosswise of a strand of hair.
