AZ 5' /N Patented Mar. 13, 1934 STTE 8 Claims.

My invention relates to a new and useful improvement in a curling rod for permanent waving and has for its object the provision of a curling rod structure which will be simple in structure, economical of manufacture, durable, highly eilicient in use, and easily operated. Another object of the invention is the provision of a curling rod whereby the end thereof may be brought into close relation with the scalp and in which a burning of the scalp, either through direct contact or by escaping` of steam, is prevented.

Another object of the invention is the provision of a curling rod of this class in which the various parts may be easily and quickly assembled.

Another object of the invention is the provision of a structure whereby the curling parts may be locked in position -when the hair is wound upon the rod.

Another object of the invention is the provision of a structure for use in connection with a curling rod which will serve to provide a receptacle for the reception of any condensate which may be formed and which will serve as a guard against the escape of steam toward the scalp.

Another object of the invention is the provision of a pair of relatively movable hair locking parts which may be easily and quickly securedin position and which will always move to a pre-determined location so that the entry slots will be in alignment for the passage of a wisp of hair thereinto.

1n the invention I use a curling rod 12 which is secured to and projects centrally upwardly from the base of a cup-.shaped member 13 having the upstanding inwardly inclined flange or side walls 14. A notch 15 is formed inwardly of this cupshaped member terminating in an elongated slot. A cup-shaped member 17 is adapted to t over the cup-shaped member 13. The upstanding flange or side wall 19 of the cup-shaped member 17 is also inclined. An opening or notch 18 is formed in the cup-shaped member 17 to conform to the contour of the opening or notch 15 and this opening or notch 18 terminates in an elongated slot 18 which is faced oppositely to the notch or slot 16. The member 17 is "fastened on the member 13 solely by its frictional engagement therewith, the member 17 snapping onto the member 13 and to this end the member 17 must be made of metal suiiiciently resilient for this purpose. When the parts are assembled in this manner, as shown in Fig. l2, and rotated relatively to each other until the pin 21 which projects downwardly from the base of the member 13 and which rides in the groove 20 formed in the upper surface of the base of the cup-shaped member 17 has reached the end of the groove the openings or

notches

18 and 15 will be in alignment so that a wisp of hair may be inserted into these openings. Thereupon, the disc or cupshaped member 17 will be rotated relatively to the disc or cup-shaped member 13. In Fig. 4 these cup-shaped members are shown in alignment and the wisp 45 of hair has been moved into the space provided. In Fig. 5 a relative rotation of these members has been eiected so that the wisp of hair engages in the slots 16 and 13' and it will be noted that the wisp of hair is shaped into arcuate form to partly embrace the curling rod 12. In order to lock these

parts

13 and 17 in position to retain the wisp of hair and prevent any undue movement of the parts the set screw 22 carried by the flange 19 is threaded against the flange 14', which prevents relative rotation of the

members

13 and 17. A. cup-shaped retainer 40 is clamped about the disc 17 and secured to the outer surface of the base of the cup-shaped retainer 40, which is also provided with an inclined resilient wall 41, is a layer 42 of heat insulating material and a layer 43 also of heat insulating material but soft and yieldable such as a layer of felt, leather, or the like. This layer 43 will engage closely against the scalp and since lthere are no outward projections from the asinto steam.

sembly the layer 43 may be brought into close engagement with the scalp. Where a number of these curling rods are used, and in giving a permanent wave a large number is always used, the curling of the hair with each rod consequently is begun at a common distance from the scalp so that uniformity of the curl is possible and a more even and symmetrical distribution and progression of the waves in the hair is effected.

The layer 23 is formed from felt or other suitable lnaterial and has slits 24 projecting inwardly, these slits being extended at right angles to each other and crossing so that a central opening is formed in the layer 23, which is placed in the cup-shaped member 13 in embracing relation to the rod 12 and the hair wound therein. This layer 23 serves as a sealing gasket and its purpose will appear hereinafter.

In order to wind the hair about the rod 12 I provide a winding device consisting of a metal plate doubled upon itself to provide the

overlying portions

29 and 30 which embrace and securely grip the rod 12. Each of these doubled over portions is provided at its edge with

knuckles

31 and 32 in each of which is positioned a

wire

33 and 34. respectively which are formed into a gripping hook 35. The wisp of hair is engaged by the hook 35 and upon a rotation of this hook about the rod l2 the hair is wound firmly around the rod 12. The lower edge 36 of these doubled over

members

29 and 30 is inclined so that as the wisp of hair is wound upon the rod 12 the winding member will, through engagement of the inclined surface 36 with the wisp of hair wound on the rod, travel outwardly and thus a uniform winding of the wisp upon the rod is effected.

After the wisp of hair has been wound upon the rod 12 it is covered with the layers 3'7 of absorbent pads or cloth saturated with the liquid which it is desired to use to produce, in co-operation with the heat, the permanent curl or wave. In carrying out the operation a heating element 38 provided with the insulating sheath or apron 39 isused. Vifhen the heat is applied, the liquid carried by the pads 37 is vaporized and turned It is quite necessary that none of this steam be permitted to pass downwardly into engagement with the scalp and it is also quite desirable that none of the condensate may reach the scalp while in a hot condition. To this end the layer -23 serves to function in conjunction with a receptacle forming sleeve 25 which is positioned in concentric relation to the rod l2, as shown in Fig. 3. This sleeve 25 is provided at one end with the outwardly projecting flange 26 having at one point the nose or projection 2'?. In assembly, the sleeve is placed in position by turning the same until the nose 27 is in alignment with the opening 15 whereupon the flange 26 may be pressed rmly into engagement with the layer 23 which serves as a sealing gasket or washer. A rotation of the sleeve relatively to the member 13 will lock these parts together through the engagement of the nose or projection 27 beneath the flange 14. In this way I provide a tight seal by pressing the layer 23 firmly between the base of the cup-shaped member 13 and the ilange 26 so that passage of liquid or steam downwardly into engagement with the scalp is prevented.

The device is one which is compact and very easily and quickly assembled even by an unskilled person. Even with unskilled labor the device may be used without danger of burning the scalp as it is impossible for leakage to occur, the seal referred to being suciently tight for all purposes. The device may also be used with any type of curling machine and the winding member serves to eliminate all necessity of tying the hair on the prong. By having the winding member formed from the pair of doubled over

resilient parts

29 and 30 the winding member may be used on curling rods of diierent size and dimensions. In this way I have provided a curling rod assembly which is adapted for universal use which is effective of a higher grade work than can be accomplished with curling rods now in use and which is absolutely safe so far as burning of the scalp is concerned.

VWhile I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
