Application March 2, 1936, Serial No. 66,685 5 Claims. My invention relates to hair curling appliances and in one form of its use is particularly of value in connection with what is called permanent wav ing of hair. 5 ' My invention is designed to provide instrumen talities by virtue of which a more thorough and uniform curling of the hair is made possible. By the use of these instrumentalities it ‘is possible to reduce the length of the uncurled hair ad ja‘cent to the scalp and it is also possible to pro vide a more uniform curl, that is, one in which the difference between the length of each wave is reduced, that is my improved device separates the strands of hair to a greater degree than has heretofore been possible so that each strand when Wound upon a mandrel does not have as large an 2 outer diameter as is customary in the present devices. Thus the wave in the outer layers of the hair more nearly approximates the length‘ of wave of the inner layers. It is another object of my invention to arrange a device of this nature which can be used with the standard heating appliances that are mount ed above the curling elements after the curling 25 elements are in place, that is, my improved de vice although providing for two strands of hair in connection with each device, nevertheless is of such a size that it would fit the standard heating unit as used in connection with other devices hav 30 ing but a single mandrel or curling element. A further advantage which accrues due to the use of my invention is that it takes less time for the steam or other heating means to penetrate the wound strand, and if steam is used, it more readily penetrates to the interior because of the smaller diameter of the curled strand. In accordance with my invention I provide an instrumentality of this type in which two strands of hair may be accommodated and I so arrange 40 this instrumentality so that it may be opened to receive the hair, and locked to clamp the same in position even though the instrumentality is placed immediately adjacent another like instru mentality in which-other strands of hair have 4 GI 50 (C1. 132-—33) Fig. 6 is a perspective view of the underlying pad; and Fig. '7 is a sectional view on line ‘I of the ex tremity of one of the mandrels. Referring more particularly to Fig. 4, I show 5 there my improved clamping device which con sists of a back plate III to which three clamping elements I I, I2 and I3 are pivotally mounted, although the central element is preferably sta tionarily arranged as shown. The clamping ele ments as shown more clearly in Fig. 3 comprise central metallic portions I4 surrounded by rubber envelopes I5. The back plate I0 is preferably an L-shaped element having upwardly projecting ?ngers I6, I‘! and IS, the slots between the ?ngers 15 furnishing a guide for the extremities of mandrels I9. The right hand extremity of the clamping element I3 (Fig. 4) is provided with a locking de vice pivotally mounted thereon which consists of an upper front plate 20 and a lower front plate 20 2|. The upper front plate 20 is likewise pro vided with three ?ngers, respectively the ?ngers 22, 23 and 24 which serve a purpose similar to the ?ngers I6, I1 and I8 in that they accommo date the opposite extremities of the mandrels 25 from that accommodated by the ?ngers I6, I‘! and I8. The right hand extremity 25 of the clamping element I2 is ?at so that it may enter between the two plates 20 and H and the same is true of 30 the right hand extremity 26 of the clamping ele ment I I. Between the upper and lower plates 20 and 2| of the locking device there is mounted a lever 21 having an eccentric 28. Thus when the three 35 clamping elements II, I2 and I3 are pressed to gether as shown in Fig. 1, then the lever 27 may be swung in a contra-clockwise direction (Fig. 4) and the eccentric 28 ?nds its position in the round side portion 27' of the element 26 and locks the 40 three clamping elements together as shown more clearly in Fig. 1. It is of course to be understood that two strands of hair are ?rst to be inserted between the clamp already been clamped. ing elements, respectively, these two strands be I will describe one form which my invention may take more in detail by referring to the ac ing shown more clearly at 29 and 30 in Fig. 3. My improved device, as before stated, is no companying drawing in which— Fig. 1 is a top view of’ such an instrumentality; commodated within the individual heating ele Fig. 2 is a partial sectional view on line 2-2 of Fig. 1; Fig. 3 is a sectional view on line 3-3 of Fig. 2; Fig. 4 is an open view of the clamping device; Fig. 5 is a view showing the arrangement of 55 various instrumentalities of like nature; wider than those now in use so that it can be ac ment used on standard machines. The scale that is used in the drawing is somewhat larger than the actual device. In the particular form of the device which is used as a basis for the drawing the width of the device roughly is a little better than one inch. 55 2 2,105,730 Before the two strands of hair are introduced between the clamping elements ll, l2 and I3, they are drawn through a pad 3|, which pad preferably consists of a felt portion' 32 and a rubber or rubberized portion 33, this pad having two slots 34 and 35 through which the strands are initially drawn and the pad placed against the scalp. These pads are separate from the clamping device or element. 10 From what has been described it will be seen that if a device of this nature is used in which the total amount of hair which is to be curled and which is drawn from beneath the device is di vided into two strands, that the length of. the uncurled hair adjacent to the scalp is consider ably less than if the hair were drawn through such a device in one strand only. Two strands likewise make it possible to have a wound strand In use therefore, the two strands of hair are .. of less~diameter than if all of the hair is wound 10 drawn through slots 34 and 35 and then inserted in a single strand. between the clamping elements ll, l2 and I3, improved devices I can utilize more on a scalp whereupon the clamping elements are locked to— . gether. The free extremities of the two strands 15 are then wound upon two mandrels I9, 19 and as the hair is being wound upon these mandrels, the mandrels approach closer to the clamping I ?nd that by the use of my gvthan?with the older type of devices. From) what has been thus described, it is thoughtthat the nature of my invention will be readily. clear .to those skilled in the art. Having, however, thus described one form which my in element until ?nally their opposite extremities - vention may. take, what I claim as new and desire pass into the slots between the ?ngers l6, l1, I8,.. to secure by Letters Patent is: l. A device for use in the permanent waving 20 22, 23 and 24, respectively. These mandrels are each provided with a ?nger 36 to thoroughly hold . of hair ‘and adapted to clamp strands of hair the extremities of the strand. Each mandrel‘ I9 has as shown in Fig. 7 a round projecting portion 31 and a square portion .38. These form part of 25 aplate 39 held in the extremity of the mandrel and so arranged that the parts 31, 38 and 39 can rotate relatively to the mandrel H? in one direc tion only. The opposite extremity of each man drel has a knurled ?nger piece 40 ?xedly'attached 30 to the mandrel and as the mandrel approaches the slots between the ?ngers the elements 31 and 42, - both'being round, permit continuous rotation of the mandrel. until it approaches the position shown in Fig. 3, whereupon the mandrel is pushed to the right (Fig. 1) so that the squared portion therein comprising three separable clamping ele— ments mounted together, and means operable at ‘one side thereof for locking said clamping ele 25 ments together. 2. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping ele ments, an end plate to which said elements are mounted, two of said elements having swinging engagement with said end plate, and a unitary locking device carried by the opposite extremity of one of said elements for locking said elements together. . 3. A device for use in the permanent waving of 35 38 enters into the slot between the ?ngers to be ‘ hair and adapted to clamp strands of hair therein there held while the mandrelvis further rotated in order to tighten the strand upon the mandrel. The locking instrumentalities shown in connection 40 with the mandrel prevent reverse rotation of the mandrel after this ?nal tightening process. In order to obtain a still tighter adjustment of the mandrel, it is provided with a plurality of holes 4! into which a small rod may be inserted 45 for that purpose, thus to obtain a greater leverage. comprising three separable clamping elements mounted together, means operable at one side thereof for locking said clamping elements to— gether, and an insulating pad having slots 40 through which said strands of hair are passed. 4. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping ele ments, an end plate to which said elements are 45 To release the mandrel it is pushed to the left to 'mounted, ?ngers extending upwardly from said release the square shaft portion from between ' end plate, two of said elements having swinging the ?ngers. ‘ engagement with said end plate, and a unitary It will be seen that because the three clamping locking device carried by the opposite extremity 50 elements ll, l2 and I3 are clamped by means of r of one of said elements for locking said elements a lever operated from one side thereof, that a second clamping device may be mounted adjacent to the onealready in position so that the two may closely adjoin, all as shown more clearly in 65 Fig. 5. I prefer to have the pads 3| overlap as shown in Fig. 5 so as to be doubly safe in guarding the scalp from the heat that is being applied from the heating elements. It must be understood, of 60 course, that the drawing illustrating this overlap ping arrangement in Fig. 5 is not exactly correct together. 5. A device for use in the permanent waving of hair and adapted to clamp strands of hair therein comprising three separable clamping ele ments, an end plate to which said elements are ,mounted, two of said elements having swinging engagement with said end plate, a unitary locking device carried by the opposite extremity of one of said elements for locking said elements to 60 gether, and ?ngers projecting upwardly from said locking device for accommodating mandrel ex nounced as shown in Fig. 5 but the pronounced I tremities therebetween. tilt is due to the fact that the parts are shown ~ MAX GOTI‘LIEB. 65 without any compressing of the pads or any in in that the tilting of the elements is not so pro equalities in the ‘scalp.
