' HAIR CLAMP FOR PERMANENT-WAVE APPARATUS I Filed Feb. 25, 1955 INVENTOR i fra .5. Masker i ATTORNEY Patented July 20, 1 937 y BAER CLAMP FOR PERMANENT WAVE APPARATUS 4 Claims.

This invention relates to an improved form of hair clamp for use in permanent wave apparatus.

In permanent wave apparatus as previously used, it has been customary to clamp each lock of hair adjacent the roots thereof with a clamp, to pass the lock of hair through a guard and place the same over the clamp and thereafter to wind the lock of hair upon a roller .and apply heat by means of a heating pad to the lock of hair thus wound, to impart a permanent wave to the lock of hair. Unless the clamp used as a part of this apparatus clamps the strands `of hair tightly, there is a tendency `for the roller to pull the hair and for the 'chemical solution produced by the moistened heating pack to leak through the clamp and burn the scalp. Moreover, `should. the operator wind the lock of hair `upon the roller lbefore passing said lock of hair through the guard, lit is necessary to unwind the hair from the roller before the guard can be placed in proper position, thus causing considerable delay.

One-object of this invention is a more'enicient clamp for a permanent-wave apparatus.

Another object is a clamp which` will prevent the hair from bei-ng pulled when wound upon. the

roller. f

Another object is to -prevent the vchemical solu- .tion produced by the heating pack from passing through the-clamp to the scalp.

Another object -is to save the time lostdue to thefailure to insert the guard before winding th hair upon the rol-ler.- Y

Other objects will appear from the detailed description which follows. Y

Clamp iii includes tie rod VIl having an elbowshaped end piece l2 secured to one end of said tie rod in any suitable manner, as by means of a rivet I3. End piece l2 includes a wedgeshaped extension portion I4. This wedge-shaped extension may be triangular, conical, or otherwise formed, so as to center in the frustoconical opening 2B formed in the tubular metal clamp member 24. End piece I2 is provided with a U-,shaped recess l5 for receiving the guideway 3l of roller 35. The opposite end of tie rod Il may be bent as indicated at i6, and is pivotally connected at I8 to the end piece Il by means of a nut and bolt, or other suitable device. End piece il is bent at right .angles to form a shoulder i9 having a shoulder post i90. for engaging in the notched end 3.5 of roller 35. End piece i1 is likewise provided with a wedge-shaped extension portion 20 which may be triangular, corneal, or otherwise formed, so as to constitute a centering ,device for the frustoconical opening 2l formed in the tubular metal clamp member 243.

Alocking lever 22 is pivoted at 2| to the end piece Il by means of Va rivet, or other suitable device, dening a pivot post kfor the lever. One end of locking lever 22 forms a cam-shaped roller 23 operable to co-operate with the extension member 32 to lock clamp members 2li and 29 together. Clamp member 2li is surrounded by a tubular rubber cover 25. Said clamp member is preferably tubular, the bore 2B ofclamp mem,- ber 24 tending to reduce the weight of the device. Bore 28 is bevelled at its opposite ends to define frustoconical openings 26 and 2l for receiving the wedge-shaped extensions lll and 2i! in the manner previously described.

The tubular metal clamp member 2li is provided with a supplemental metal clamp member 29. Member 29 is flattened on the side adjacent to member 24 so as to present a substantial gripping area for clamping the hair between the tubular rubber covers 25 yand 3A, thereby preventing the lock of hair from being drawn through clamping members 2d and 2S when roller clip 35 is rotated towind the lock of hair upon roller 38. Clamp member 29 is provided at one end with any `.ear 3d, which is pivoted at 3| to the end piece CFI A roller clip is used in association with clamp I0. Said roller clip includes a roller 33 journalled in a notched end member 35. The opposite end of roller 38 is provided with a circumferential guideway 3l adapted to engage in the U-shaped recess I5 of clamp I B. Roller clip 35 is also provided with a clamping trigger 39, concavely curved to conform to the contour of the roller 33, said trigger being pivoted at relative to the roller, so that by the movement of clamping trigger 39 the end of the lock of hair may be wound about roller 38 (see Fig. 6) and the clamping trigger 33 then closed against the hair Wound on roller 38 to lock the strands of hair in place preparatory to winding the balance of the lock of hair upon the roller 38.Y Fig. 3 indicates the position of the clampV ID and roller clip 35 after clamping trigger 39 has been brought into contact with roller 38 and the balance kof the lock of hair wound tight upon roller 38 and trigger 39 of roller clip 35.

A chemical pack 4I adapted to be moistened to generate heat is then placed around roller clip 35 (see Figs. 4 and 5) and is retained in place by means of pack holder 42. The pack holder'consists of jaw members 43 and 44 (Fig. 6) which are hinged together at their opposite ends by means of jaw hinges 4'1-47. Jaw members 43 and 44 are also provided with thumb and nger latches -45 and a suitablespring 46 co-acting with the thumb and nger latches to tension the jaw members and maintain them in closed position, as shown in Figs. 5 and 6.

The principle of operation is as follows: with the-clamp in the open position shown in Fig. 1 a lock of hair is passed between

clamp members

24 and 29, clamp I0 being placed on the scalpgclose to the roots of the hair. Y Clamp

members

24 and 29 are then brought together under finger pressure until roller cam 23 engages in the recess 33 of extension 32, whereupon locking lever .22 is moved from the position shown in Fig. 1 to the position shown in Fig. 2, and the strands of hair are now tightly clamped between the oppositely disposed faces of the tubular rubber covers 25 and 34. The wedge-shaped extensions I4 and 29 eoact with the bevelled openingsV of bore. 28 of clamp member 24 to draw

clamp members

24 and 29 in substantially parallel position, the wedge-shaped extensions I4 and 29 dening a plurality ofV adjustable fulcrum points for clamp member 24. This results in bringing all contacting parts of the tubular rubber covers 25 and 34 to substantially equal tension so that all strands of the clamped lock of hair are held under substantially equal tension, thereby preventing any of the strands from being drawn through the clamp Ywhen roller clip 35 is operated. The free end of the `lock of hair is now placed upon the roller clip as shown in Fig. 6, the clamping trigger 39 is then pressed against roller 38, and roller clip 35is now rotated to roll the lock of hair upon roller 38 and trigger 39, and roller clip 35 is brought into co-operative relation with clamp i, as shown in Fig. 3. After roller clip 35 has been brought into proper association with clamp I9 as shown in Fig. 3, the roller 38 is rotated in the U-shaped recess I5 by means of a suitable key inserted in an axially disposed key-way 5i) in roller 38 shown dotted and by the rotation of the roller, the slackness, if any, is removed from the `lock of hair which is thus tightly wound in proper position. The chemical pack 4I is then placed over the. hair and moistened, and pack holder 42 placed around pack 4I as indicated in Figs. 4 and 5.V Any tendency for roller 38 to unwind is prevented by the frictional engagement of the hair against rubber covers 25 and 34 and the clamping action of pack 4I and pack holder 42. The chemical solution generated by moistened pack 4I will impregnate the hair rolled on roller clip 35, but owing to the tension exerted upon

clamp members

24 and 29 by locking lever 22 no part of this solution will leak through the rubber covers 25 and 34 to the scalp, thus eliminating any risk of burning the scalp with the chemical solution generated by pack 4I. After suitable time has elapsed, the operator removes the holder 42, the pack 4I, unwinds the hair from roller clip 35, and releases clamp I9.

Clamp member 24 is rotatable about the ful crum points formed by the wedge-shaped extensions I4 and 2|] seated in the frusto-

conical openings

26 and 21, thereby permitting the member 24 carrying tubular rubber cover or rubber roller 25 to be rotated, to permit the rubber to wear evenly. Tubular rubber cover or rubber roller 34 may be rotated on the clamp member 29 so as to present an unworn contacting surface opposite the contacting surface of rubber roller 25. The

tubular rubber'covers

25 and 34 may be renewed when worn, the former by first removing the nut and bolt of pivot I8, and the-latter by merely withdrawing the worn out cover 34.

It should be understood that when clamp I0 is closed as shown in Fig. 2, the contacting faces of the

rubber rollers

25 and 34 are compressed against'the tension exerted by the roller cam 23 in the recess 33 of extension 32, and the pressure between the contacting faces of the

rubber rollers

25 and 34 prevents the strands of hair from being drawn through the said rollers when roller 38 is rotated to wind the lock of hair thereon.
