Application May 9, 1936, Serial No. 78,926 1 Claim. (01. 132-34) This invention relates to curlers for use in permanent Waving the hair. , Heretofore it has been the practice to use spin dle-like structures having relatively rotatable 5 parts and after the hair has been wrapped there around and fastened to the respective parts of the curler, one of the parts of the curler has been rotated relative to the. other to tighten the wrapped hair on the curler and hold it until the 10 hair has been heated and steamed sufficiently to retain the' curl. In tightening the wrapped - hair, however, some of the whorls have been pulled more tightly than others due to the fric tional contact of the hair with the surface of 15 the elongated spindle on which the whorls are formed. Consequently the whorls of hair at one end of the curler have been drawn tighter than those at the other end. This has all resulted in unsatisfactory work in the lack of perma nency and uniformity of the finished waves and 20 curls. An object of the present invention is to elimi nate the uneven distribution of tension on the coiled hair by providing the spindle portion of IO 01 the curler with anti-friction devices so that the wrapped hair on the spindle will not drag on the spindle when subjected to tension by a twist ing action of the rotatable parts of the curler but will move longitudinally of its stands without ob jectionable frictional resistance, thereby insur ing uniform stretching of all of the 'convolutions of the wrapped hair. With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts herein after more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. In the accompanying drawing the preferred form of the invention has been shown. In said drawing: Figure 1 is an elevation of the curler with hair wrapped therearound and held tightly. Figure 2 is a central longitudinal section, a portion being broken away. . Figure 3 is a perspective View of one of the anti-friction members. 7 Figure 4 is an elevation of the complete curler. Referring to the ?gures by characters of refer ence, I designates the handle of the curler with a concentric recess 2 in one end. A rod 4 is 55 anchored at one end in handle I while its other end is anchored in a head 5 preferably tapered toward its free or outer end which is slotted lon gitudinally as shown at 6. V The recessed end 2 of handle i is rotatably mounted on one end of an elongated spindle section 7 and the rod ii is also rotatable in said section. One end of the spindle section is made smaller and a spring 9 is anchored at one end and wrapped therearound, the several convolu tions of the spring being normally expanded 10 against the wall of recess 2 so as to serve as a spring clutch which allows the section ‘i to rotate in one direction independently of handle I but holds it against retrograde movement relative to 15 the handle I. Mounted on rod d between section 1 and head 5 is a series of alined cylindrical spindle sec tions it all rotatably mounted independently of each other and abutting at their ends. The end sections H can be tapered down to the diameter of the section I and head 5 respectively. The outer faces of the sections 1, IE] and I! are flush and cooperate to form a spindle hav ing a smooth outer surface formed of relatively rotatable portions and the outer surface of sec tion I can be tapered or otherwise shaped so as to be easily gripped between the ?ngers of one hand while handle I is being held by the other hand. In practice that portion of a lock or wisp of hair I-I nearest the scalp is tied to head 5 by a cord placedin slot 6 as shown at a. The hair is then wrapped about the curler and tied by another cord to the section ‘I as shown at b. The operator grasps section ‘I and the tied hair thereon in one hand and turns it in one direc tion while handle I is being held in the other hand. Head 5 thus is held against rotation while the section 1, which can rotate only in one di rection because of spring clutch 9, will pull the, 40 hair about the sectional spindle and uniformly tightenand stretch the convolutions. During this operation the hair will cause independent rotation of the sections ill and H so that fric tion will be eliminated and all of the convolutions of hair tightened and stretched equally. As the clutch prevents retrograde movement of the sec tion ‘I, the hair will be held tightly after the twisting or curling operation until it is desired to release it whereupon the cords a and b are re 50 moved and the curler can be withdrawn. What is claimed is: A curler including a handle, a head, a rod connecting the handle and head, an elongated spindle section mounted for rotation on the rod 55 2 2,108,374 and projecting into and rotatable within the handle, said section having one end tapered to provide a ?nger grip, means within said section for holding it against rotation in one direction relative to the handle, additional shorter spin dle sections mounted for rotation on the rod be tween the head and the elongated spindle sec‘ tion, all of the sections abutting and being rotat able independently, said shorter sections coop~ erating to provide a spindle portion tapered at one end toward the elongated section and at its other end toward the head thereby to provide a 5 bulge.
