4 Claims. (Cl. 132-36) The present invention relates to permanent waving and more particularly to a novel and improved permanentwaving machine.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawing, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawing:

Figure l is a side elevation, partly in section, of a permanent waving machine embodying the present invention, certain parts being omitted to show the construction more clearly;

Figure 2 is a detailed plan view, partly in section, of the embodied means for frictionally engaging and supporting the flexible conductors of the permanent waving machine; and

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

The present invention has for its object the provision of a novel and improved device for frictionally engaging and supporting the flexible conductors through which current is supplied to the curl heating means of the permanent waving machine. Another object of the invention is the provision of an improved permanent waving machine in which the flexible conductors are supported in a plurality of staggered rows from a single supporting means.

Referring now in detail to the illustrative embodiment of the invention as shown in the accompanying drawing, a supporting standard In is provided, which may be mounted on a suitable base (not shown), and encloses a pair of conductors which supply current, preferably at low voltage, to two distributing rings ll supported on the standard I0. Rings II are electrically connected with the flexible conductors l2, of which only two are shown, and at the lower end of these conductors are attached the curl heating devices or contactors l3 which are adapted to be positioned around the curls to be permanently waved or to be connected with the heating pads wrapped around the curls. A guard casing I5 is provided surrounding the distributing rings l l and is supported in any desired manner from the standard I0.

Means are provided for engaging and frictionally holding the flexible conductors l2 in any desired position, at the same time permitting 5 these conductors tobe slid up and down to position the contactors or heaters l3 at the desired height with reference to the customers head. For this purpose, a supporting ring I6 is provided positioned immediately below the distribut- 10 ing rings II and supported on the guard casing l5 by means of the brackets l1. Supporting ring I6 is provided with a plurality of cord gripping devices for individually gripping and frictionally supporting the flexible conductors, and in accordance with the present invention these cord gripping devices each comprise a pair of jaws having adjacent concave faces 2| conforming generally to the shape of the exterior of the flexible conductor l2.

Jaws 20 are preferably identical and are formed with a rounded portion 22 extending for substantially half the vertical distance of the jaw. These portions 22 are apertured to receive a pivot pin 23 by which the jaws are pivotally mounted, one jaw being in the reverse position of the other. Pivot pin 23 is mounted in the upper and lower portions 24 of a small c-shaped frame 21 fitted over the supporting ring I6. Adjacent to the pivot pin 23, each of the jaw members 20 is provided with a laterally extending part 25 which is recessed to receive a small coil spring 26 bearing against the supporting ring l6, thus tending to urge the jaws 2|] resiliently towards each other and into cord gripping position.

Springs 26 also serve to frictionally hold. the cord gripping devices against sliding movement along the supporting ring IE but more positive means may be provided for maintaining these devices in the desired position. For this purpose, ring I6 is formed with a plurality of apertures 28 suitably spaced around the ring I6 and adapted to cooperate with the boss 29 projecting inwardly from the vertical portion of frame 21.

As shown in Figure 2, alternate cord gripping devices extend away from the supporting ring in opposite directions so as to provide two concentric, staggered rows of cord gripping devices and conductors l2, thus giving a better distribution of the conductors and heaters over the customers head.

In use, the contactors or heaters l3 are positioned about the wound tresses of hair properly prepared for waving, and after being so positioned the flexible conductors l2 are drawn upwardly,

sliding between the jaws 20, until they are at the proper height to support the entire weight of the heaters or contactors l3.

In case it is necessary to replace a conductor or heater, it is not necessary to remove the cord gripping device from the supporting ring, but the conductor may be pulled from between the jaws 20 and replaced by another without disturbing the cord gripping device on the ring.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.

What I claim is:-

1. In a permanent waving machine, the combination of a support, a frame slidable on said support, a pivot pin carried by said frame, a pair of jaws pivoted on said pin, extending away from said support and provided with cord gripping faces, said jaws being provided with oppositely extending portions, recesses in said portions opening towards said support and springs in said recesses bearing against said support for resiliently urging said jaws together and yieldingly frictionally holding said frame against sliding movement on said support.

2. In a permanent waving machine, the combination of a support, a plurality of jaw members for engaging and frictionally clamping a cord, a frame on which said members are pivoted, said frame and members being slidable on the support, and means for resiliently pressing said jaw members together, said means being positioned between said jaw members and support and also serving to normally hold said members and frame against sliding movement on the support.

3. In a permanent waving machine, the combination of a support, a frame mounted on said support, a pair of jaw members for engaging and frictionally clamping a cord, a pivot pin carried by said frame and on which said members are pivotally mounted, spring means positioned between said members and support resiliently urging said members into clamping position and means for holding said frame on said support in a definite position. v

4. In a permanent waving machine, the combination of a support, a pair of pivoted jaw members having cord clamping faces, a frame fitted over said support, a pivot pin for pivoting said jaws in said frame and preventing removal of said frame, and spring means for resiliently pressing said jaws together and holding said frame firmly on said support.
