CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE HAIR-GRIFFING FASTENER 4Application Bled December 81, 19,27. Serial No. 243,827.

The present invention relates to an improvement in hair. gripping fasteners designed particularly for use with short or bobbed hair.

fiattening The hair gripping fastener of the present invention belongs to that class in which the fastener isconstructed of metal having qualities of springiness. Hair fasteners ofthis type are generally made from flat material having a greater width than thickness, and are known as the Hat or snap type of fastener. Such fasteners have a distinct advantage over the oldstyle of fastener made of substantially springless round-wire in that they exert a substantial gripping force upon the hair to hold it firmly in place, which function the old springless round wire Atype does not perform.

Hairpins made of spring material which are known in the prior art comprise a length of fiat spring material, for instance, metal, of substantially greater width than thickness, said thickness being substantially uniform throughout their entire length, being bent to provide an open loop and two legs, which may or may not be crimped, being so arranged as to predetermined points. The cost of manufacturing the snap type of fastener of the prior art` is relatively high becausel ythe material used, which is flat spring wire of substantially uniform thickness throughout its length, is more expensive than ordinary round wire, it being. necessary to Hatten the round wire stock by an expensive rolling and operationbefore it is ready for use as raw stock; that is, the stock is pre-fiattened to an intended substantially uniform thickness. The flat wire when bent to form the connecting loop for the two legs of the fastener is materially weakened, which often causes the latter to break at this 'point when the legs are spread apart in inserting and fasthe legs contact eachV other at advantages hithertolunknown in this art.

The fastener of the present invention comprises two legs of spring material, preferably metal. of greater width than thickness, integrally connected into a single unitary structure by means of a loop of substantially round spring material of greater thickness than the legs. The thickness of each leg is substantially less at its extremity than adjacent -the connecting loop, the change in thickness being gradual throughout thek length of each-leg. The width-of each leg is substantially greater at its extremity than adjacent the connecting loop, the change in width being gradual throughout the length of each leg. One of the legs may have one or more crimps which cause the fastener to more firmly grip the hair. The relatively thick connecting loop provides not only a strong round or U-bend loop less likely to break, but also provides a greater spring tension upon the legs than does the loop of the prior art made from flat material, which greater tension causes the legs to more firmly grip the hair than do'the'fasteners known in the prior art. The decreased thickness of each leg toward its extremity causes it to bow and thus be spread further apart at the extremities than fasteners having legs of uniform thickness throughout their length, thus making their application to the hair easier-than with fasteners of the latter type. The increased width of the legs toward their extremities furnishes them with more surface withwhich to grip the hair than fastened portions above described during the` operation of forming the fastener.

Mafny important objects, features and advantages w1ll be more particularly apparent from the .following detailed description.

In the drawings, Fig. 1 is a erspective view illustrating the use of the hair gripping fastener.

Fig. 2 is a side elevational view of the hair gripping fastener of the present invention, in normal position.

Fig. 3 is a top planview,b of the same.

p which may be connected by means of a loop in Fig. 4, the legs may be 3, which loop may be constructed of a substantially round length of resilient material, such as metal', of greater thickness than the legs 1 and 2. The legs'2 and connecting loop 3 may be integrally connected into a single unitary structure, which is of advantage not only in use but in cost of manufacture. One of said legs, for instance, leg 2, may be provided with one or more crimps i intermediate its length. Each of the legs l' and 2 is prefcr'ably 'substantially thicker adjacent its connection to they loop 3 than adjacent the ends thereof, as will be more apparent from Fig. 1. Each of the legs- 1 and 2 may also be of Substantially greater width adjacent their extremities than adjacent the loop 3 (Figs.

2 and 3), the'change in width being gradual throughout their length.

.In manufacturing the hairpin of the present invention/ the crimps 4 may be so arranged that their b-ases may or may not contact the face of the straightleg 1. It is preferable, however, that a base of one or the crimps, such for insta-nce, as shown at 5, shall contact the face of the straight leg l, for the purpose of providing a limited point of contact between the'legs which will cause them to more effectively grip the hair. The free extremity7 of the le 1 may extend in substantially a horizonta plane, while the extremit` `6 of the crimped leg 2 may be upturne at anangle fromthe plane of the straightjleg '1 to facilitate the insertion of the in into-the hair. The terminals 6 and 7 of e legs ma be rounded to prevent the pin from scratching the wearer lor-cutting the hair while being inserted, as well as to facilitate the insertion of the pin into the hair.

In inserting thehair grip in the hair, it is first necessary to pry the extremities of the two legs a art,i nsert the fastener in the hair while sai legsare separated, as shown in Fig. 4, the legs lbeing permitted to spring together to grip the hair therebetween, as illustrated in Figs. 1 and 2.

As will be noted, we have so constructed the pin as to ut the spring in the legs entirely and su stantially vto the exclusion of the connecting loop. Therefore, as shown bowed around without transmitting the flexure thereof to the heavy thickened loop portion 3. This prevents breakage of the pin at the loop por- Y pending opposed leg portions, said eg h y t e its extremity, and an integral connectin bend for said legs, said bend being of a su stantially greater thickness than said le 3.
