'I'his invention concerns a clasp or clip for forming waves in the hair, that is, for arranging, giving form to and holding hair waves, having sides pressed on to each other lengthwise under the influence of a spring, which sides are provided with lower edges curved according to the shape of the head and inner rows of teeth lying opposite to one another, but taking up their position in gaps, and further provided with iinger gripping members for opening thel clasp.

According to this invention the teeth are so formed and are disposed in such a position on the sides of the clasp, that the longitudinal direction of each tooth is obliquely disposed in relation to the curved line connecting the bases of the teeth of a row.

A further characteristic of the invention lies in the fact that the sides of the clasp are bent in a. lateral direction.

In order'that my invention may be better understood, reference may be made to the accompanying drawings, in which Fig. .1 shows hair `waves as they are formed on the head, naturally or artificially; Fig. 2 is a partly broken side elevation of one embodiment of the improved clasp; Fig. 3 is a plan of the iirst embodiment, as viewed from above, in Fig. 2; Fig. 4 is a front elevation of the same, in closed position; Fig. 4a is a transverse section, with the hair wave secured, the section being taken upon the line IVw-IVa of Fig. 8, looking toward the left, in Fig. 8; Fig. 5 is a view corresponding to Fig-4, with the parts shown in extended position; Fig. 6 shows in plan a second embodiment; Fig. 7 is a perspective view of the same; Fig. 8 is an elevation corresponding to Fig. 2, with further parts shown in dotted lines;

, Fig. 9 is an underside plan of the embodiment shown in Figs. 2 to 5, inclusive, and Fig. 8; Fig; 10 is a section corresponding to Fig. 4a, but looking toward the right in Fig. 8; and Fig. 11 is an underside plan of the modification shown in Figs. 6 and 7..

- In Fig. 1, the ridges of the crests of the waves are marked A-B and C-D. The hair, as clearly shown in this Fig. 1, runs at an oblique angle to' these ridges A-B and C-D, not perpendicular thereto. With the known forms of clasp, the

` teeth on the sides are so formed, and-are disposed on the sides in such a position, that the longitudinal direction-of the-teeth runs perpendicularly, orl approximately so, tov the curved, connecting base line. When such a clasp is applied to a hair wave in the usual way, the teeth thereof, at their gripping points, force the hair out ofvits natural, oblique, illustrated position in relation to the direction of the ridge A-B or C-D, with the result that the wave arranged or formed by the clasp becomes distorted.

With the embodiment according to Figs. 2 to 5, each of the two lengthwise extended sides or 5 jaws 3--4 of the clasp with the iingergrips 10-'11 disposed thereon, is made from sheet metal. These sides or jaws are connected together by means of` a pin 5 which passes through holes in lugs 6 bent over from the hand grips. 'I'he edges 10 of the clasp sides 3-4 are curved to conform to the shape of the head and a rim 12 is bent back Aoutwardly from the extremity of each clasp side along a curved line '1. A. spring 8 fitted around the pin 5 tends to press the sides 3-4 against 15- each other.

y In the curved line 'l of each of the clasp sides 3-4 are disposed the bases of the teeth 9-9a. The teeth 9-9a which are pierced from the clasp lsides are'bent back inwardly thereof in such a 20 way that the longitudinal direction of eachtooth runs obliquely in relation tc the line '7, so that the line of projection from the reduced extremity or tip of any tooth-intersects the line of its base outside the base of the tooth. The teeth of both 25 sides are so disposed in relation to each other that when the clasp is in its closed position, the teeth of the one side engage in the gaps between the teeth of the other side and with the teeth near the vouter ends bearing on the outwardly 30 bent rims 12 (Figs. 4and 10). In the closed position, the extremities of at least some of the teeth 9-9a project beyond the lower edge of the

sides

3 or 4 against which they lie, which edge is curved to the shape of the head (Figs. 2 and 8). The 35 object of this construction is to enable quite short hair to be secured by the clasp.

When the clasp is seen in side elevation, as in Figs. 2 and 8, the line of projection 14 (Fig. 8) from the tip of any tooth of a row intersects the 40 line connecting the bases of the teeth at a point outside the base of the particular tooth. In the closed position of the clasp, as is particularly shown in Figs. 2 3, and as seen in edge view from below in Fig. 9, the line of projection 15 (Fig. 9) 4U from the tip of any particular tooth of the row of one side intersects the line connecting the bases of the rows of lteeth on the other side of the clasp 'at approximately the beginning of the the base of an adjacent tooth in the latter row.

As is shown in Figs. 4, 4a and 10, the sides 3-4 of the clasp, when the clasp is in closed position, do notfcontact at the base line '1 of the teeth, but are held vapart by the contact of the teeth with the rims 12, and the sides are also spaced the clasp is closed, lie at an angle such that the sides converge from the back edges to the base line of the teeth.

When using the clasp, the finger grips sides 10-11 are pressed together against thepressure of the spring 8, whereupon the clasp opens and the teeth 9-9a are set apart from each other. The clasp is then xed on a hair wave at the point of a wave crest, that is to say, along the ridge A-B or C-D of such a wave (Fig. 1) Then the grips sides 10-11 are slowly released so that the teeth 9-9a, engage in the hair in such a way that they are,y disposed approximately in the direction of the hair lying obliquely in relation to the direction of the ridge of the wave.

By virtue of the fact that the teeth 9-9a, running obliquely in relation to the curved line 7, engage in the hair in the same direction as the hairl itself takes, the position and fall of the hair are not disturbed, and, by virtue of the fact that the sides 3--4 of the clasp lie near together only on the curved line 7 and are set apart outy side the line, the possibility of spoiling the wave or pressing it fiat is also avoided.

Thus the waves, as far asytheir maintenance is concerned are not detrimentally affected by the use of the new clasp from the standpoint of airiness (ventilation) and looseness but are for the rst time given their correct form and are thus advantageously influenced, as is shown particularly in Figs. 4a and l0.

Owing to the oblique position of the teeth as illustrated and described, in comparison iwith clasps of the known types, in which the teeth run vertically in relation to their base line, considerable advantages accrue from the use of this clasp. The hair is held considerably more securely by means `of the clasp and an unintentional loosening of the hair from the teeth of the clasp is rendered difficult.

According to the second embodiment (Figs. 6, 7 and 11) ofthe invention, the clasp sides 3-4 are bent in such a manner that the line 7 in which the base of the teeth 9-9a are set, is curved in two planes that is to say longitudinally as shown in Figs. 2 and 8 and laterally as shown in Figs. 6 andll, whereby the arrangement or holding of hair waves running in a curve is made possible.

The clasp may be modified in various respects in relation to the embodiment illustrated and described. For example, the teeth, instead of having a at surface, may be given any other desired and suitable form; for instance, they may have a slight undulation, and at the ends, instead of being pointed, they may be rounded off.

Instead of the ends of all teeth, when closed, projecting over the lower edge of the clasp side against which they lie, their Aforrn may be such that the ends of only certain teeth project over the lower edge.
