Claims.

In the conventional type of appliance used for maintaining strands of hair in the form of coils while subjected to heat-treatment in a drier there are two lever-like members normally held in clamping relation to' the coil by a spring and which present planiform faces to each other and hence to the. coil. Such an appliance where it directly exerts clamping'pressure holds the coil in more or less flattened state so that, following the drying treatment and when the appliance is removed, the flattened zones thereof appear unduly conspicuously in the resulting curl. An ap pliance is also known which, instead of including clamping members which would present flat or planiform faces to each other, includes clamping members which have a line-contact with each other thus, when applied to a coiled strand that is to be subjected to heat-treatment, appreciably, though not completely, mitigating the mentioned deformation of the ultimate curl; and it fails to hold the curl fixed.

By the present invention an appliance for maintaining a strandof hair in coiled state for undergoing treatment in a drier is provided which acts rather as a clasp than as a clamp. That is to say, there being two members pivoted together and a spring to hold them normally in operative relation'to the coil, one such member is undulated as viewed in side elevation so that two lengthwise-displaced portions thereof are arched away from the first member, whereby the appli ance embraces the coil at two diametrically opposite portions without clamping it. An important feature in respect to the two arches is that the one which relatively adjoins the pivot has its spread more limited than that of the other whereby the first arch will hold the coil at one point thereof in compact state and at another point the other end will accommodate both the coil and the portion of the strand extending from the scalp and hold them in compact state. No pressure is to be exerted on the coiled strand, though said members confine it to the coiled format three diametric points, or in the space surrounded by and at both sides of the coiland in fixed relation to the scalp.

Several forms of my invention are herein shown, simply by way of example.

In the drawing,

Fig. 1 is a side elevation and Fig. 2 an end elevation of one form of the appliance;

Fig. 3 is a plan view thereof in clasping relation to a coiled strand of hair;

Fig. 4 is a plan view of member a of such form;

Figs. 5 and 6 are plan views of the members of another form; and

Fig. 7 is a similar view of a member corresponding to member b of the first form.

Referring, first, to the form shown by Figs. 1 to 4:

Both members a and b are formed of stiff sheet material, as metal. The member a which is to adjoin the scalp comprises an elongated narrow tapering tongue I, a body portion 2, a relatively short arm 3, and a pair of ears 4, the tongue I and arm 3 projecting in opposite directions from the body portion 2 and the ears 4 upstanding therefrom, the part of said member which forms the tongue and the part which comprises the body portion and arm being both planiform, with the latter tilted downwardly somewhat relatively to the former part. The other member b comprises an elongated tongue 5 which is preferably generally appreciably wider than the tongue I, a body portion 6, a relatively short arm 1, and a pair of ears 8, the tongue and arm projecting in opposite directions from the body portion and the ears depending therefrom, the part of the member which forms the tongue and the part which comprises the body portion and arm being both planiform, with the latter part tilted upwardly somewhat relatively to the former part.

Related as shown in Fig. 1 the ears of member a are between the ears of member b, the two pairs of ears being penetrated by a pintle 9 whereby the members are pivoted together. A spring l0 coiled about the pintle and having its ends bearing against the arms of the two members holds their tongues bearing against each other.

But member b is undulated, being arched adjacent and remote from the hinge-forming portions 2-4 and 6-'-8 of the members, said member being normally held by the spring in contact with member a at preferably both of two points, as between the arches and at its free end as shown in Fig. 1. And preferably, also, member 2) not only tapers to its free end but is reduced in width between the arches as seen in plan, Fig. 3.

When the coil :1: has been formed in the hair strand as shown in Fig. 3 the appliance is opened by pressure and the arms 3-1 and then allowed to close with the strand positioned as there shown, or so that the coil in one zone thereof, i. e., under the arch which adjoins the hinge or pivot, is clasped and hence confined, without compression, by the members, and under the other arch the diametrically opposite zone of the coil, together with the tangent part at of the strand, is clasped and hence confined, also without compression.

The two arches have difierent spreads (or dimensions lengthwise of the appliance) because the bulk of the strand under the former arch is less than that under the other. The narrowing of the width of the member b between the arches is preferred: thereby the coil is not held distorted at its center from circular form so that such distortion would become set in the curl as the incident of the drying. As is apparent from Figure 1, the arch of the elongated tongue Ii which is nearer the pintle 9 is of appreciably greater height although, as before mentioned, it is of materially less length, than the arch remote from the pintle, that is, that shown at the left in Figure 1.

In Figs. 6 and c'and d are members corresponding to members a and b, respectively, and formed identically the same as such members except as follows: Member c has two diverging tongues ll instead of only one. Member d has its tongue l2 formed as appears in plan as a rectangular loop. The two members are to be hinged together and subjected to spring-pressure the same as in the construction first described.

Fig. 7 shows a member corresponding to member b or d and having the same form as they except that its tongue I3 is trident-shaped. This member may be hinged to a member such as a and subjected to spring-pressure the same as in the construction first described.

The member a or c in any of the forms, being without the arches, is the one which, when the appliance is in operative state, lies next to the scalp.

Thus I maintain the strand coil in coiled state and in a definite relation to the appliance by clasping instead of clamping it, that is to say, by arching one of the members over the coil at diametrically opposite portions thereof and having the members quite contiguous to if not in actual contact with each other at points alternating with the arches. Preferably the tongue of each member is formed so as to present narrow surfaces to the coil. Thus, the tongue-portions of the members a and c are narrow and the tongue-portions 5, I 2 and I3 present to the coil narrow surfaces, due to the apertures 5a in Fig. 3, the space I2a in Fig. 5 and the spaces I 3a in Fig. 7. In the examples the appliance is shown as comprising separately formed and assembled parts, which isnot material so long as the appliance includes two elongated superposed portions (as l and 5 or II and I2, for instance) extending generally lengthwise of each other and one of which closely adjoins the other at three lengthwise disposed points thereof and one of which is arched from the other between each two such points and one of .which is arched from the other between the other two such points and the appliance includes means elastically resisting angular displacement of one of said portions from the other around an axis in transverse relation to such portions and at one side of which both arches are disposed. Whereas usually the member, as a, which adjoins the scalp will usually have its tongue devoid of the arching, my invention is not necessarily thus limited.

Further, whereas the appliance is particularly useful in effecting heat treatment in the forming of curls it is also not necessarily thus limited.

Having thus fully described my invention what I claim is:
