1,931,443 HAIRPIN mm J. Los'ec, New York, N. Y. Application April 22, 1933. Serial No. 667,429

1 Claim.

This invention relates to hair pins.

It is the aim of the present invention to furnish the hair dressing art with a hairpin that will encompass a relatively wide lock of hair and 5 hold the lock firmly in desired position; and which will have a positive closure clamp for the passage 7 between the prongs to prevent single strands of hair from becoming loose; and which will provide gripp'ng fingers for additional anchorage inter- 10 mediate the ends of the prongs; and which will furnish a curved prong of a general curvature of the head next to the scalp for the comfort of the user; and that is a neat and dainty ornament for the hair.

Further objects of the invention are to provide a hairpin that is strong, compact and durable, thoroughly reliable for its intended purpose; that is formulated along simple lines to promote economy of manufacture, and that is comparatively simple to apply and remove from the hair.

With the foregoing and other features in view,

ters denote corresponding parts throughout the several views:

Figure 1 is a plan view of a lock of hair showing in top plan view the hairpin of the present invention attached thereto.

Figure 2 is a detailed section taken substantially on line 2-2 of Figure 1.

Figure 3 is an enlarged side elevation of the hairpin removed from the lock of hair.

Figure 4 is a detailed vertical section taken substantially on line 4-4 of Figure 3, and looking in the direction of the arrows.

Figure 5 is an enlarged fragmentary section taken substantially on line 55 of Figure 3 and looking in the direction of the arrows.

Referring to the drawing in detail, the metal hairpin of the present invention .is preferably formed in one piece and made with a prong A that lies next to the scalp and an outer prong B, both of which merge at their inner ends with an integral U-shaped loop 6, which loop is round in cross-section.

The width ortransverse dimension of the loop 6 is slightly greater than the width between the prongs to furnish a tension normally urging the prongs toward each other.

Both of the prongs A and B are flat relatively thin bars sufiiciently stifl to resist deformation along their length but they will yield toward or away from each other about the loop 6 which radius of the scalp prong is substantially of the same general radius as the head so that it will not bear uncomfortably against the scalp.

An intermediate portion of the outer prong B is formed with a series of V-shaped insetcrimps 7, the apices 8 of which construct the width of the passage 9 between the prongs tofurnish a series of gripping fingers which gripping fingers provide additional anchorage for the hair. The free end of the outer prong B is formed with a depending roll 10 that is normally urged under tension against the face of the terminal 11 of the scalp prong A. This roll 10 provides an abutment to limit the length of the passage 9 and also a closure clamp to prevent single strands of the lock of hair L from ravelling loose from confinement in the passage 9, which feature is meritable inasmuch as the hairpin will not slip from the lock of hair to which it is engaged.

The roll 10 is formed of the metal at the free end of the outer prong B, and this construction makes the outer prong shorter than scalp prong B, permitting the terminal 11 to be utilized similar to a keeper for the closure clamp formed by the roll without any furthermodification to the scalp prong A. The outer extremity of the diameter of the roll 10 is substantially tangent to the plane of outer prong B, while the inner extremity is substantially tangent to the curvature of the scalp prong B.

merging at their inner ends in an integral U-s haped loop, said loop constituting a yielding hinge and being of greater transverse dimension thanthe width between said prongs, one of said prongs lying next to the scalp beingcurved to conform to the general contour of the head and JOHN J. LOSEC.
