DEVICE FOR CURLING HAIR Filed March 51, 1941 Patented Sept. 1, 1942 UNETED STTES PATENT OFFICE DEVICE FOR CURLING HAIR Herbert A. Winkelmann, Chicago, Ill.

Application March- 31, 1941, Serial No. 385,992

3 Claims.

The invention relates to a device for curling hair. The device comprises a rod or tube of generally cylindrical or elliptical form whose surface is provided with a series of slanting grooves, all slanting in one general direction.

An object of the grooves slanting in one direction is to facilitate the removal of the curl after it has been wound around the rod.

Other objects and advantages of the invention will become apparent as the following detailed description progresses, reference being had to the accompanying drawing, in which Fig. 1 is a side elevation of the hair curling device having a comb attached to one end of the curling rod;

Fig. 2 is an enlarged fragmentary view of the curling rod of Fig. 1, showing details of one form of groove;

Fig. 3 is a. cross-section along line 3-3 of Fig.

Fig. 4 is a modified form of the curling device showing a different type of slanting groove.

Referring to Figs. 1, 2 and 3, wherein the preferred embodiment of the device is shown, the reference character I designates a rod I having a series of grooves 2, the plane of bisection of each groove slanting in the same direction as the plane of bisection of each of the other grooves and slanting at an angle to the axis of the rod other than 90.

Preferably, as shown in detail in Fig. 2, both sides of the groove 2 slant on the same side of a plane which is perpendicular to the axis of the rod.

In the embodiment shown in Fig. 4, one side 3 of each groove is at an angle of 90 and the other side 4 of each groove slants at an angle other than 90 but each side 4 slanting in the same general direction from a plane perpendicular to the axis.

There may be a series of grooves on opposite sides of the rod but one series of grooves along the top of the rod as shown in Fig. 1 is sufficient.

The curling device may be made of metal, wood, glass, hard rubber, or synthetic plastics such as nitro-cellulose, cellulose acetate, acrylate resin, styrene, ethyl cellulose, vinyl resins, or the like.

The curling device may be a portion of another accessory such as a comb, brush, or the like,

The curling device is used as a corkscrew might be used by pushing and tightening as the curl is formed, and then since the serrations or grooves run only in one direction, it can be extracted without disturbing the curl.

While there have been shown and described certain embodiments of the invention, it is to be understood that it is capable of many modifications. Changes, therefore, may be made without departing from the spirit and scope of the invention as described in the appended claims, in which it is the intention to claim all novelty inherent in the invention as broadly as possible, in view of the prior art.

I claim:

1. A device for curling hair comprising a rod having a succession of slanting grooves wider than they are deep whereby the hair will readily slide out of the grooves, said grooves extending along the length of the rod and all slanting in one general direction from the surface of the rod toward the axis of said'rod.

2. A device for curling hair comprising a rod having relatively shallow surface grooves wider than they are deep in succession along a major proportion of its length, the bisecting plane of each of said grooves slanting in the same general direction as the bisecting plane of each of the other grooves and at an acute angle to the axis of the rod.

3. A device for curling hair comprising a rod having a, handle containing comb teeth on one end and on the other end a succession of slanting grooves wider than they are deep along a major proportion of the length of that part of the rod which is adjacent the comb teeth, said grooves all slanting in one general direction from thg surface of the rod toward the axis of said ro HERBERT A.
