6 Claims.

This invention relates to the hair waving art and consists in a novel protector clamp device for use in permanent waving.

In the Croquignole method of permanent waving, the hair is wound upon a curling rod in flat strands from the outer extermity towards the scalp. A protector clamp is applied to the strand as near as possible to the base thereof to shield the scalp and prevent pulling of the hair in winding, and the rod and Wound strand are seated against the clamp during the application of heat. The protector clamp is usually formed of a pair of elongated hair gripping jaws pivotally connected at one end and with padding on the hair and scalp engaging surfaces and upstanding members at the ends for engaging the ends of the curling rod. Ratchet means are usually provided on the rod and clamp for tightening the curl.

jaws are rectangular in form and have smooth or longitudinally corrugated hair gripping edges. With this type of device the jaws may not snugly grip the edges of the strand, particularly if the .strand is of substantial thickness, with the result that steam and moisture may be permitted to leak through the clamp.

It has been suggested to provide cooperating V-shaped recesses in the hair engaging faces of the jaws for collecting the hair in a pencil-shaped strand so that the hair will be snugly engaged on all sides. However, due to the length of the clamp which must be arranged for supporting the curling rod in a prone position, substantial portions of the hair between the scalp and the Vsingle hair receiving opening in the clamp, and between the clamp and the extremities of the rod, cannot be curled.

An important object of the present invention is to provide a protector clamp particularly adapted for Croquignole waving and arranged to shape the hair in pencil strands and at the Sametime permit curling the hair close to the scalp.

A more detailed object of the invention is to provide a clamp of the above type having a plurality of restricted substantially circular hair rev ceiving recesses therethrough.

Another object is to provide separately acting yielding means for tightly gripping the separated bunches of hair engaged by the clamp regardless of its relative size with respect to the hair receiving opening in the clamp.

Another object is to provide an improved and '55 simplified protector clamp of the above type, for

Ina familiar form of protector clamp, the

use in Croquignole waving, which may be easily manipulated.

These objects and others are attained substantially by the device illustrated in the accompanying drawing in Which- Figures 1 and 5-are top and bottom views, respectively, of the clamp in open position.

Figure 2 is a top view of the clamp applied to the hair.

Figures 3 and 4 are sectional views of the clamp taken substantially on the corresponding section lines of Figure 2, the hair being omitted.

Figure 6 is a side view of the clamp assembled with a curling rod and wound strand of hair.

Figure 'l is a view of the clamp in partly closed position.

The novel protector clamp includes, broadly, a pair of elongated jaws l and 2 pivoted together at one end, as at 3, with a latch device at the other end including link 4 pivoted to jaw 2 and a manipulating lever 5 with a cam 6 pivoted to link 4; and arranged to seat in a depression 7 in the corner of jaw 1. The bottoms of the jaws are padded by means of strips 8 and 9 of felt, or similar material. At the left end of the clamp (Figures 1, 2 and 3) is an upstanding member 10 having a concave upper surface 11 for seating the corresponding end 28 of the curling rod (Figure 6), and a spring pawl 12 for cooperation with ratchet 13 on the rod. Link 4 is provided with an upstanding finger 14 for engaging the other end 29 of the curling rod.

The jaws 1 and 2 are of U-section with their open edges facing each other and provided with V- shaped recesses 15 and 15. The bottoms of the recesses 15 in jaw l are semicircularly recessed, as at 17, and recesses 16 in jaw 2 are enlarged at the bottom, as at 18. The edges of recesses l5 and 16 extend substantially the entire length of the jaws and the adjacent edges merge in pointed salients 19 and 2G, referred to hereafter.

As shown in Figures 3 and 4, the upper wall 2a of the jaw 2 is inserted between the walls 1a and 1b of the jaw 1, and the jaw 2 is substantially thinner than jawl in order that the bottom of the clamp may be nat. Bottom wall 2b of jaw 2 is deeply recessed, as at 21 and 22, in order to snugly accommodate the lower wall of jaw 1. The enlargements 18 in upper wall 2a oi jaw 2 are elongated in order that the corresponding depressions in walls 2oJ and 2b may extend the same depth into the jaw.

Pivoted to the ends of jaw 2 are a pair of levers 23 which extend longitudinally between the walls of the jaw and have semicircular recesses 24 in their inner edges. A wire 25 of spring material has end portions 26 extending through the closed outer edge or back of jaw 2 and then bent towards each other and engaging the levers 23 near the adjacent ends thereof. Ends 26 of the wire constitute separately acting springs urging Ythe levers towards the hair engaging edge of jaw2. A projection 27 on the upper wall of jaw 2 is in position to engage shoulders 28 on the ends of the levers 23 to limit the rotation thereof `under the influence of springs 26.

The recesses 15 and 16 and the enlargements 17 and 18 in the bottoms thereof are so positioned that when the jaws 1 and 2 are brought together in the closed or operative position of the device the solid part of each jaw overlaps the recesses in the other jaw and pairs of enlargements 17 and 18 form alined circular hair receiving openings through the spaced walls of jaws 1 and 2 on each side of levers 23.

In operation the novel protector clamp device is applied near the base of a segregated flat strand of hair in the usual manner. As the jaws are swung together, the pointed salients 19 and 20 divide the strand and the sloping edges of the recesses 15 and 16 form diminishing openings (see 30, Figure 7) which direct al1 of the engaged hair in two bunches into the openings formed by enlargements 17 and 18. The levers 23 will be depressed by the hair so that the jaws may be fully closed and the latch device swung into locking position. With the link 4 and lever 5 substantially in alinement, and cam 6 resting in seat 7, the levers 23 will engage the hair lightly so that the segregated bunches S and S mayY be pulled through the hair receiving openings to seat the pads 8 and 9 as close to the scalp T as possible. When lever 5 is swung to the locked position in Figure 2, the hair will be firmly secured between the jaws.

Both bunches are then wound from their outer ends inwardly in the well known Croquignole fashion upon a single curling rod and when the rod is seated against its support members l0 and 14 (Figure 6), the hair may be tightened by means of pawl and ratchet 12 and 13, and any suitable heater applied. If, after the hair is' tightened, it is found that it is necessary, for some reason, to loosen the rod, this may be effected, without opening the jaws, by the simple expedient of swinging outwardly the latch link 4 suiliciently to clear the end of the rod.

The device is unusually simple in operation Asince it may be gripped in one hand and the hair applied with the other, the recessed jaws functioning, as shown in Figure 7, to properly divide the engaged strands and direct them into the hair receiving openings. The separately operating spring levers readily adapt themselves to bunches of hair of varying thickness, as indicated in Figure 2, or, if no hair enters one of the recesses, the corresponding lever 23 will close the same, preventing the escape of steam or moisture to the scalp of the customer. The hair in each bunch S, S will be drawn from a relatively small section of the scalp so that there will be no long uncurled hairs between the scalp and the rst wave.

Certain features of the embodiment disclosed have been previously known and these and various details may be modied as will occur to those skilled in the art. For instance, it would be within the spirit 'of the invention to provide a different number of recesses in the jaws, such as three or four in each. The exclusive use of all such modications as come within the scope of the appended claims is contemplated.

Vhat is claimed is:

1. A hair clamp device comprising relatively movable members recessed to form longitudinally spaced openings for receiving segregated bunches of hair, and independently acting yielding elements in said openings for engaging said bunches in the operative position of the device to close said openings around said bunches regardless of the relativesizes thereof.
