UNITED STATES PATENT OFFICE ,WILBUB S. LEWIS, OF LAKEWOOD, OHIO, ASSIGNOR TO THE NESTLE LE MUR GOMFANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO HAIR CURLER Application filed June 15,

My invention relates to curlers upon which strands of hair are coiled and stretched during the heating operation of permanent waving processes.

In forming permanent waves 111 human hair, it is customary to divide the hair into strands which are coiled around curlers of desired design and secured, and then stretched lengthwlse while secured 1n coiled relation. Such curlers are generally formed I rotated in either direction while the sections are moved longitudinally relatively. It is objectionable to adjust the sections lengthwise in order to rotate them relatively to stretch the strands of hair because of the additional operation which requires time. Sections which can be rotated in one direction only are objectionable because operators become proficient in coiling the strands in either one direction or the other, and with this class of curlers the operator is required to coil the strands in one direction.

An object of my invention'is to provide a tension device for a curler composed of coaxially extending sections whichwill permit relative rotation of the sections in either direction without longitudinal adjustment and which will prevent the tension of the stretched hair from rotating the sections relatively.

A further object of my invention resides in the provision of a simple, inexpensive curler which is comprised of relatively rotatable sections which can be readily assembled together to prevent relative longitudinal; movement.

These and other objects and the invention 1925. Serial No. 37,106.

itself will appear in the following detailed specification. T In the accompanying drawings, Figure 1 is a side elevation of a curler embodying my invention; Figure 2 is a longitudinal sectional view of the same; Figure 3 is a side elevation of the rod section prior to assembly with the tube section; Figure 4 isa transverse sectional view of the assembled curler taken on line 1 15of Fig. 2; and Figure 5 is t a transverse sectional view of the assembled curler taken on line 5-5 of Fig. 2.

Referring now to the drawings by characters of reference, 10 represents onesection of a curler which is a tube open at each end and preferably formed of round metal. The other section 11 of the curler is prefer'ably'formed of metal and is in the form of a rod which is of slightly less diameter than the interior wall'of the tubular section.

The rod section extends co-axially through the tube section, and is flattened at one end to provide a finger grip 12, which the operator can grasp to rotatethe rod. The other end 1-3 of the rod projecting from the tube is also flattened vandis provided with a slot 14: in which a string, extending around a strand of hair can be secured. The flattened ends of the rod are formed of sufiicient width to also in diameter and provided witha longitudinally extending slot 16 in which the clutch or tensioning mechanism is anchored. The tension mechanism Consists of two leaf springs 17 and18, which have one end inserted in the slot16 in the rod. The springs extend around the rod in oppositedirections and bear against the inner wall of the tube 10, being under sufficient tension to frictionally prevent relative rotation of the rod and tube sections unless manual rotative pressure is applied. The rod can be rotated'in either 95 direction when the operator grasps the end I 12 of the rod andexerts sufficient pressure to overcome the frictional tension exerted by the springs.

- ,The rod section 11 is preferably formed of 10 standard rod stock. Prior to assembly of the rod with the tube, the portion 15 is reduced and slotted and the flattened slotted end 13 is formed. The springs-are then inserted in the slot 16 and are bent around the rod whereupon the rod is inserted through the tube with the end 19 (Fig. 3) unforme'd. After such insertion the end 19 is flattened to provide the grip 12 and to retain the tube against longitudinal movement relative to the rod. It will, be understood that either one or both of the flattened ends 12 and 13 could be formed after the rod, with the springs assembled, is inserted through the tube.

In utilizing the curler for a'waving process", a strand othair is gathered from the scalp, after being treated'with a'soitening solution, and is tied adjacent the scalp to the slotted encl13 of the red by a string. The free endof the strand is teen coiled tightly aroundthe tube, either over or nude" the StlIHQln a direction toward the grip 12 and is tied tothe tube at the end of the coil. By holding thetube the coiled hair will be stretched by rotating the rod 11. T he spring tension agaii'istthe tube is sufficient to prevent rotation of the curler sections, so that the tension of the stretched hair will not ro-' tate the curl-er section'srelatively.

Various changes can be made in the structure described herein without departing from the spirit of my invention and the scope of what I claim.-

' What I claim is 1.. A curler for carrying and stretching strand of human hair comprising a tube upon which a strand of hair is coiled and secured, a red extending through said tube having an enlarged end to which the strand of hair is secured adjacent the scalp, a finger grip at the other end or" said rod for rotating said rod relative to said tube to stretch the strand coiled on said tube, and laterally extending friction means disposed intermediate a side ot the rod and'said tube and disposed inter-, mediate the ends of the tube for preventing the tension oi said strand of hair from rotating said tube and said rod relatively.

2. A. curler rod, around which a strand of hair may be coiled in either direction and stretched, comprising two co'axially extend ing rotatable members secured together to prevent relative longitudinal movement, and a spring secured to one of saidmembers at intermediate portion t er-eat and en" the other of said in} here at a ltneral suiiace thereof to put the members under lateral tension, the tension of said spring aganst 1 member being gr aterthan the tension of he stretched hair, one of the members project ng beyond both ends of the other member and comprising at one end a handle portion and at the other end a hair strai'id securing portion.

3; A carter around which a strand of hair may be wound in either direction and stretched comprising a tube, a slotted rod extending through said tube and having enlarged ends to prevent relative longitudinal displacement of said tube therefrom, and a pair of oppositely extending springs having one end anchored. in the slot in said rod and frictionally bearing under tension against an inner wall of said tube, said springs preventing' relative rotation of said tube and rod until overcome by the manual rotation of said rod.

4. A curler for a strand of hair comprising a tube, a rod extending through said tube, said rod having its projecting ends flattened after insertion through said tube to secure said tube against longitudinal movement on said rod, one of said flattened ends providing a finger grip for rotating said rod relative to said tube, said rod corn-prising a portion disposed midway of its length, spring-pressed into frictional engagement against the inner walls of the tube.
