P. J. GRAHAM HAIR CURLER Filed July 12,'1959 ATTORNEY Patented Junev4, 1940 UNITED STATES HAIR CURLER Philip J. Graham, Worcester, Mass., assigner to Delamere Company, Inc., Jersey City, N. J., a corporation of Delaware Application July 12, 1939, Serial No. 283,975

3 Claims.

This invention relates to a hair curler of the type comprising a pair of pivo-tally connected, spring-pressed, cooperating members between which the ends of the hair are engaged and on which it is wound, said cooperating members having associated therewith a swingable clamp member which is adapted to be swung into closed position over the wound hair to keep if from unwinding.

The cooperating members of curlers of this type are generally made of metal and are provided with handle portions that extend rearwardly beyond the pivot so as to permit of conveniently opening the two members against the action of the spring. The spring usually consists of a U-shaped leaf, or a Wire coiled about the pivot, having its ends bearing against the handle portions.

'I'he principal object of this invention is to provide a construction in which the cooperating The invention comprises the novel features of construction and arrangement of parts hereinafter described and illustrated in the accompanying drawing, in which- Figure 1 is a side elevation of the curler;

Fig. 2 is a longitudinal section thereof, on an enlarged scale, with the front ends of the cooperating members broken away; and

Fig. 3 is a cross-section taken on the line 3 3 of Fig. 2.

The device comprises two cooperating members I 0 and II each having a handle portion I2 at its rear end. The forward portion I3 of the member ID, upon which the hair is wound, is of cylindrical or yslightly taperedv tubular form, while the forward portion I4 of the member I0 is of concavo-convex form to fit, in its clos'ed position shown in Figure 1, over'the top of the forward portion of the member Il).

The members I0 and II of this invention are each formed entirely of molded plastic material. They may be formed in a mold, by any suitable molding or extrusion process, of any suitable molding composition or material, either thermosetting or thermoplastic, such for example as cellulose acetate, or plastic resins.

The device is provided with the usual clamp member I5 formed of wire having inturned ends I 6 and carrying a roller I1 at its outer end for 5 fastening the clamp in closed position. Other suitable fastening means may be used instead. 'I'he inturned ends I6 pivotally connect the members I0 and I I together, although a separate pivot pin may be used if desired. 10

The member II is formed with ears I8 at its sides adjacent the pivotal point which ears have holes through which the inturned ends I6 of the clamp pass. The member Il) is formed with depressions I9 in its sides into which the ears t 15 and it has a transverse hole in alignment with the holes in the ears for receiving the inturned ends of the clamp.

The parts and construction heretofore described are all known` in the art except for the fact that 20 the members I0 and II of the present invention are made entirely of molded plastic material.

In carrying out the present invention, as shown in Figures 2 and 3, I provide the member I I with an internal recess 20 in the enlarged portion 2| 25 in the vicinity of the pivot. The member III is likewise provided with a corresponding recess 22 in its enlarged portion 23.

24 is a U-shaped spring having two arms 25 that lit into the

recesses

20 and 22, respectively. 30 It will be noted that the bend of the spring faces to the rear and that its arms extend forwardly well beyond the pivotal point of connection of the two members I0 and II so as to bear on said members at their enlarged portions.

The lower inner wall 26 of the entrance to the recess 20 and the upper inner wall 21 of the entrance to recess 22 are inclined towards each other, as best seen in Fig. 2, to provide clearance for movement of the spring in opening the members I0 and II.

What I claim is:

1. In a hair curler of the type described, a pair of cooperating members of molded plastic material pivotally connected together, each having a handle portion protruding rearwardly of the pivot,

a U-shaped spring having its arms extending forwardly into recesses in the interior of the cooperating members above and below the pivot, the lower inner wall of the entrance to the upper recess and the upper inner wall of the entrance to the lower recess being inclined rearwardly toward each other.

2. In a hair curler of the type described, a pair of cooperating members of molded plastic mateof cooperating members of molded plastic material each having a rearwardly protruding handle portion, said members having laterally overlapping portions about which they turn with respect to each other, and a U-shaped spring having arms fitting into recesses in the interior of the cooperating members and extending forwardly beyon the overlapping portions thereof.
