Patented Jan. 30, 1940 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to improvements in hair curling clamps and. rods, more particularly to such devices employed in what is known as the Croquignole waving of hair wherein the hair strands are wound on a rod and held by a clamp preliminary to the application of a heating medium thereto.

It is among the objects of the invention to provide improved means for locking the curling rod to the protector clamps when winding of the hair thereon has been completed.

A further object of the invention is the provision of a curling rod having an external ratchet at one end thereof and a spring biasing means at the opposite end whereby the ratchet teeth coact with a rigid pawl provided on the protector clamp.

Still a further object of the invention is the provision of a curler rod and protector clamp in combination which shall be of durable and economical construction and which shall be free from clogging by foreign particles.

These and other objects of the invention will become more apparent from a description of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Fig. 1 is a top plan view of a protector clamp in the open position;

Fig. 2 a top plan View of the assembled protector clamp and curler rod embodying the principles of this invention;

Fig. 3 a vertical cross-sectional view of the curler rod taken longitudinally along the lines 33, Fig. 2;

Fig. 4 a transverse cross-sectional view of the clamp and rod taken along the line 44, Fig. 3; and

Fig. 5 an end elevational view of the curler rod.

With reference to the several figures of the drawing, the structures therein illustrated comprise a clamp constituted by the hinged jaws l and 2 pivoted at 3 and provided with a lock lever 4 that constitutes no part of the present invention, the clamp in its closed position having lever 4 lying adjacent one side as shown in Fig. 2.

The numeral 5 generally designates the curling rod which is adapted to be mounted on end brackets 6 and I of the protector clamp, the rod being so mounted by journals 8 and 9.

Both ends of the rod 5 are recessed at H] and. II, the recess lll being of square shape to receive a winding key by which suitable tension is applied to the hair strands after they are wound on the rod. The recess I I which is counterbored as shown is adapted to receive the journal pin 8 and a coil spring l2, the latter abutting one wall of the recess H and the shoulder on the journal pin 8, whereby the latter is normally biased outwardly from the curling rod l l to seal the recess H and prevent treating fluid and grit or hair from clogging the recessand working parts. The end of the rod opposite the resiliently mounted journal pin 8 is provided with a ratchet toothed face l3 which interacts with a stationary pawl 14 clearly shown in Fig. 1 of the drawing, the biasing pin 8 forcing the curler rod 5 against the pawl [4 with teeth l3 at all times in' engagement therewith.

In the operation of the above described curler rod and protector clamp, the latter is clamped with its faces engaging strands of the hair that have been separated to be curled, the clamp being placed adjacent the skull with a protecting felt therebeneath. The ends of the separated hair strands are then wound around the curler rod which is engaged at its ends by the operator who continues turning the rod to wind the hair while bringing the rod nearer the clamp and when it is all wound the rod is snapped in the brackets 6 and I of the protector clamp as shown in Figs. 2 to 4 of the drawing. The key for winding the rod to apply the necessary tension to the hair strands is then inserted in the recess [0 and the rod is wound while in the protector clamp journals to impose the desired tension upon the hair strands, and the pawl M will hold the rod 5 in any angular position against the tension of the hair strands. Suitable heating means is then applied either by the so-called heatless pad method or electrical resistance or steam heating methods or in any other suitable manner to permanize the strain imposed upon the hair by the curling action.

It is evident from the foregoing description of this invention that the provision of the ratchet teeth on the end face of the rod with the spring biased journal pin at the oposite ends is a positive means of applying and maintaining the necessary tension on the hair strands and a convenient means of winding the hair after it has been curled on the rod element.

The accessibility of the teeth permits keeping them clear from foreign matter so as to avoid interference with their proper function as in other types of ratchet devices heretofore in use, particularly those obtained with the curler rod. The spring biasing means employed provides a rugged and inexpensive construction which is not subjected to failure through breakage or tortion.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A protector clamp and curler rod having cooperativeratchet elements at one of the end faces of said-clamp and rod in cooperative endisgagement and having a spring element disposed
