Description

Sept. 19, 1939. N; L. SOLOMON AUTOMATIC RINGLET CURL-ER Filed Aug. 14, 1937 INVENT A'ITORNEY Patented Sept. 19, 1939 UNITED STATES sATI-LNT OFFICE 15 Claims.

The present invention has to do with curling hair and specifically deals with an improved and efficient curling device for readily forming ringlet curls. The object of the invention resides in the provision of a clasp for initially clamping a strand or tress of hair and a removably rotatable key adapted to be projected into the clasp for curling the hair between the jaws of the clasp to form a ringlet curl. Other objects, advantages and features of the invention will appear from the following description considered in connection with the accompanying drawing in which:

Fig. 1 shows a view of the clasp according to the invention attached to a strand or tress of hair before the latter is curled into ringlet formation.

Fig. 2 is a view of the clasp embracing a ringlet curl.

Fig. 9 is a plan view of a modified clasp, and

Fig. 10 is a side view of the clasp shown in Fig. 9 associated with a removable key of the type shown in Fig. 6.

The ringlet curler according to the invention comprises a hair clasp C and a removable key K. The clasp includes complementary hair clamping jaws l0 and l I having lugs l2 pivotally supported on fulcrum pin or shank 13 of rivet M which has its outer ends upset to prevent displacement along shank l3 of the normally diverged and reinforced manipulating portions I5 extending from the jaws.

Cooperating with the manipulating portions l5 are the outer terminals I6 of a coiled spring I! having its inner end abutting fulcrum pin or shank IS. The action of terminals [6 is to normally hold the manipulating portions l5 diverged for holding the jaws closed as shown in Fig. 4.

Each of the jaws II] and l l of the clasp is provided with a centrally arranged aperture or opening [8 which removably receive a reduced bifurcated depending portion I9 of the member or key K, the arrangement being such that when a strand or tress of hair is interposed between and clamped by the jaws of the clasp, as shown in Fig. 1, a portion of the tress is accessible and disposed across the alined openings [8.

The reduced depending part or fork IQ of the key is then inserted into one of the openings l8 and over the portion of the tress traversing these openings whereby the legs Zflof fork l9 straddle the exposed and accessible part of the tress which serves as the origin of the ringlet curl to be formed,

The upper expanded part 2| of key K forms with the reduced fork [9 an annular stop shoulder 22 which limits the insertion of the fork 19 into the alined openings IS, the inner faces of which serve as annular bearings to guide the rotational displacement of the fork at a time when the handle 2| is rotated.

During such rotation, the tress, now straddled and grasped by the fork, starts to wind about the reduced fork i9, thus translating the formerly relatively straight tress held under slight compression between the jaws of the clasp into a plurality of successive convolutions. In other words, the reduced fork winds the tress but always against the resistance of the pressure imparted by the perforated jaws due to the action of the coiled spring ll. 7

Having completely wound up the tress between the jaws, the reduced fork is removed from the sides of the ringlet curl now formed between the jaws and from the alined openings or bearings of the latter. This maybe conveniently accomplished by applying an outward thrust to the handle 2| of the key.

With the key removed from the jaws of the clasp, the ringlet curl formed is left therein under pressure created by the jaws due to the action of the coiled spring. To remove the ringlet curl, the operator merely moves the manipulating portions of the clasp towards each other, thus separating the jaws and the latter maybe readily removed from sides of the formed ringlet curl which now sustains itself in form without requiring external support.

In the embodiment of the clasp according to Figs. 7 and 8, the jaws l0 and H thereof are bowed, that is, these jaws have convex surfaces facing each other and projecting from these surfaces are a plurality of radially but spaced ribs 23 emanating from the circumferential edges of openings l8 of each jaw. The object of these ribs is to prevent accidental displacement of the ringlet curl after it has been formedbetween the jaws. In other aspects the embodiment according to Figs. 7 and 8 is along the lines of the form illustrated in Figs. 14 inclusive and is utilized in a similar fashion in connection with a key of the type shown in Fig. 6.

In the embodiment shown in Figs. 9 and 10, the clasp is in the form of a one piece U shaped loop of sheet metal having jaws or arms I0 and I l integrally merged to a U shaped bend or elastic joint 25. Each of these jaws also includes a free outwardly extending terminal 26 or lip to facilitate the insertion of a tress of hair into the clasp. The inherent resiliency in the bend tends to hold jaws l0 and I I closed, for example, as shown in Fig. 9. In similar fashion, the construction according to Figs. 9 and 10 cooperates with a key K of the type shown in Fig. 6.

While I have described my invention in detail and have referred to specific applications thereof, I do not intend that the several embodiments herein disclosed shall be limited to such specific applications, but intend that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
