PERMANENT WAVE PROTECTOR Filed 001;. 14, 1937 lllllllllllll @III I-IIIIIII II! M Patented Nov. 15, 1938 UNITED? STATES- PAT o FFrcia 12 Claims.

The invention relates to a permanent wave protector and-has as a general object'to provide a new and improved device of-that character.

A' more particular object of the invention is- 5, toprovide apermanent wave protector having a new and improvedshield for the recep'tion of a chemical pad employed in the baking of awave.

Another object is to provide a p'ermanent wave' protector having a shieldfor the-reception of a 1mchemical pad employed in -the-baking of 'a wave which is releasably attached to the clamp of the 1 view taken approximately along the line 3 -3- of Fig. 1.

While'the invention is susceptible of various modifications and alternative constructions, it is shown in the drawing and will be described hereinaiter in a preferred embodiment, butit-is not intended that the invention is tobe limited there- 40 by, but it is intended to cover all modifications and alternative constructions falling within the spirit andscope ofthe invention as defined by of hair to be waved adjacent the-scalp, a winding rod II upon which the'hair is wound, and means .generally designated-l2 for*holding the winding rod 1 against rotation after the hair has been The clamp comprisestightly. wound. thereon. two arms 1 or jaws I3 and which are pivotally secured together at one end andareyadapted to 55 he-latched together at the; other end; and". when latched assume a parallel relationship. Each arm has a metallic core consistingof 'sheetmeta'l strips l5 and l6,- respectively, bent to'ha-veageneral U-shape intransverse cross section. Surrounding each co'reisa split; molded'rubbercasing I'lflwhich has secured to the bottom side thereof a felt pad l8 in order further and effec tivelv'to prevent the-transmission of heat from the protector to the scalp and head'of the person whosehair is beingwaved. In addition to serving as insulators, the rubber casingand the felt pads 18- constitute the means for gripping the"- hairand, therefore, are made sufii'ciently' large so that they are firmly pressed 1 together in grip-'- ping' relationship' whenth'e clamp" is inlatched position.

As stated, the arms l3 and I!" are pivotallv secured'to'gether at one endand herein this is accomplishedby theinsert'ion between thelegs of "the U-shaped strips-li' a'n'd l6 of "a cross plate 20 and securing the same by rivets 2|. Outwardly ofthe ends of the 'strips- I5 and' IS; the" plate 20 is bent upwardly at'right angles to form an upstanding ear 22. Preferably-the endof 1 one strip; herein the strip I5; is squared so that it forms arigidconnection with the plate 20, while the end of the other'strip', herein the'strip I6} is rounded=(see Fig. 6) so that that strip may pivot with respect to th'eplatefll-and'the'arrn I33 The meansfor latching the free ends of the arms l3 and" I4 inclam'ping relationship comprises a lever'25pivotally mounted at 26 between a strip ZIandthe parallel portion'of'aplate 28- which, like the plate-'20, has a portion bent at right angles thereto to constitute an upstanding car 29; Theplate 28'andth'e'strip 21 are pivotal- 1y secured 'asby a rivet 3ll"-on thetop and the bottom side ofthe' strip I6. The"corresponding' end of" the strip l5 has'secured theretoa nose 3| (see Fig! 6) with which'cooperates a"cam 32 carried byth'e lever for urging the arms I3 and 14 toward clamping engagement, and-Se curingthe arms in latched position. Each of the upstanding ears is formed with an outwardly opening slot 34 for the reception-of the winding rodl I, as will presently be described.

As best seen' inFi'gss 1 andwB; the winding rod ll includes a .clip 36 which is pivotally mountedr at one end of the rod and which overlies the center of the rod'ztosecure'a'hankiof'shair there to. Preferably the rod-hasa. successively decreasing diameter from its ends toward" the middle and at the middle "is knurled to; aid: the-clip" 36 in securing the hair. At:eachw-end the rod has a .reduced portion 31 adapted=to-be received in the slots 34 as the hair is wound upon the rod ll.

At one end the rod II has fixed thereon a key 39 by means of which the rod may be revolved, after it is in the slots 34, to effect a final tight winding of the hair about the rod. At the other end, the rod H is formed with teeth 40 to constitute part of a pawl and ratchet device serving to hold the rod l l against rotation. Cooperating with the teeth 40 is a pawl 4| pivotally mounted at 42 on the upstanding portion 29 of the plate 28. An arm 43 of the pawl extends beneath a leaf spring 44 secured by a rivet 45 to the plate 28 and is urged thereby toward engagement with the teeth 40 of the rod I I.

It has been the practice in the past to bake the wave into the hank ofhair wound upon the rod II by the application of heat generated electrically, but more recently it has become, the practice to bake the hank of hair by the application of a chemical heat generating pad. Means is provided herein for aiding in the application of such a chemical heat generating pad to the hank of hair wound on the rod l I. However, in order that the clamp and the rod may be used for elec tric as well as chemical baking, this means is removably attached to the clamp. As disclosed herein the means takes the form of an elongated channel-shaped shield 41 which is adapted to be mounted directly on the clamp In between the upper surface thereof and the Winding rod ll. Extending longitudinally of the shield, centrally thereof, is a slot 48 opening through one endof the shield to permit the shield to be passed over a hank of hair secured in the clampby movement of the shield transversely of the hank of hair. In order that the shield may be readily removable from the clamp for various reasons, and yet may be easily and quickly mounted on the clamp and secured thereon so that it will not be in the way during the winding of the hank of hair on the rod l I, it preferably has a mechanical interlocking engagement with the clamp at one end and a simple frictional engagement at the ;other end. To that end, the end of the shield through which the slot 48 opens is formed with a notch 49 and the upstanding ear 29 is undercut at 50 and 5| so that it may be received within the notch 49 and also form shoulders retaining ;that end of the shield 41 against outward movement. Similarly, the other end of the shield is formed with a notch 52 wide enough to receive the upstanding ear 22. This ear, however, is not undercut but there is riveted to the shield 41 a ;leaf spring 53 which frictionally engages the ear 22 when the shield is mounted on the clamp yieldably to retain the shield against dropping off of its own accord. Preferably the end of the shield 41 having the notch 52 is strengthened and reinforced by a transverse bead 54 and by bending inwardly the portion 55 of the shield severed .thereof, though removably attached to the protector proper, nevertheless is so mounted that it does not interfere with the winding of the hank of hair onto the winding rod.
