HAIR CURLER.

Application filed July 29,

This invention has to do with a hair curler and it is an object ot the invention to provide a simple, eliiective and improved device of this character.

It is an object of this invention to provide a simple, effective and convenient means for holding hair in place on a hair cnrler, tor instance, on a. curling iron.

Another object of this invention is to provide an electric hair curler Which is sirnple, practical and inexpensive in construction.

The various objects and features of iny present invention will be best and more fully understood fromk the following detailed description ot a typical preferred form of the invention throughout which description reference is had to the accompanying drawings in it.

Fig. 1 is a side elevation of a curler, embodying the present invention. Fig. 2 is a detailed sectional View of the curler illustrated in Fig. 1. Fig. 3 is an enlarged detail sectional view of a portion of the curler being a view taken as indicated by line 3 3 on Fig. 1. Fig. 4 isan enlarged detailed transverse sectional view of the curler being a view taken as indicated by line 1&4 on Fig. 1 and Fig. 5 is an enlarged detailed sectional view of the curler taken as indicated b v line 5 5 kon Fig. 1.

The curler or iron provided by this invention is preferably in the form of a T, having a shank portion l() and across-arm 11 at the outer end of the shank. This particular form of curler is useful for forming what is known as marcel waves in thehair. A method of applying the hair to such a curler is fully set forth in United States Letters Patent No. 1439,271 issued to me December 19, 1922. The shank and crossarm of the curler are both substantial half round in cross-sectional configuration and are formed of two sections A and B. The( section A is T shape in plan configuration to correspond with the general shape of the curler and is in the form of a. flat plate having its edges turned to form flanges 12. The section B is shaped to conform with the section A and is curved so that it is substantially half round in cross-sectional coniguration. The sections A and B lit together so that the edges oi' the Section B engage the outer edges of flanges 12 in the manner clearly illustrated in Figs. 4 and 5 of the 1924. serial No. 728,852.

drawings. This construction provides a curler substantially halt round in cross-sectional configuration, which shape is partienlarly desirable as it presents comparatively sharp corners 13 around which hair can be wrapped in a manner to give it a particularly desirable curl.

The sections A and B of the curler maybe secured together by caps 15, applied to the outer ends of the cross-arrn 11 and a handle 16 connected with the inner end of the shank 10. The caps 15 close the ends of the crossarm and are eitective in preventing the hair from slipping from the ends of the cross` arms. dentations 16, which (zo-operate with correspending indentations inthe cross-arm to hold the caps on the ends of the cross-arrn.

The handle 16 may be. formed of Wood or other suitable material and may be of any suitable size and length. The handle tits tightly over the enlarged inner endl'porf tion 18 of the shank 10 and is secured on the shank by suitable screws 20, which extend through the handle and .into the shank. In the preferred form of construction `a sleeve orftubular part 19 is carried in the enlarged part 18 of the shank and the screws 20 extend into the sleeve.

In accordance with ythis invention a tie 23, for instance, inthe form of a string or tape, has one endconnected with a suitable part of the device and is adapted to be wrapped around or lover hair applied to the iron to hold it in place. In the preferred form of construction the tie 23 has one end connected to a ring 24 freely carried on the shank 10, between the cross-arm 11, and the enlarged part 18. In use` the ring 24 allows the fixed end of the tie to come at the hair carried on the iron. In practice the free or outer end of the tie may be held by the operators hand at the handle 16 or may be otherwise suitably secured.

The means provided tor heating the curler includes a heating element or resistance Wire carried on a suitable core 31 arranged in the cross-arm 11, an electrical connector 32 in connection with the handle 16 and a suitable connection between the connector 32 and the resistance wire 30.

The core 31 has a body part which extends longitudinally through the cross-arm and is provided at its ends with enlargements 34 which iit more or less closely in The caps 15 are provided with inersy core and section A of the curler in the man*` ner clearly illustrated in Figs. 3 and 4 of the drawings. The body of the core, which is the part of the core which carries the resistance wire, is substantially half round in cross-sectional configuration to correspond to the cross-arm, and is provided with suitable grooves or indentations 36 to carry vxthe wire 30. The een ral or middle portion of the wire is carried in a groove 37 extending longitudinally of the core and the two end portions of the wire are wrapped spirally around the core in the indentations 36 from the outer ends of the core to the middle of the core opposite the Ishank 10.

rlhe electrical connector' 32 is arranged at the inner end of the handle 16 in an opening 40 which extends longitudinally through the handle. rlhe particular connector illustrated in the drawings includes apair of contact pins 41, carried in a suitable body 42. The body 4:2 is screw threaded into a suitable holder 44, tightly carried in the opening 40. n

The electrical connection between the resistance wire 3G in the cross-arm and electrical connector 82 atthe inner end of the handle may include flexible conductors connected to the contact. pins 41, compara-Y tively heavy wires 46 which extend through the shank 10 and carry the ends of the resistance wire, and suitable connections between the wires46 and the ends of the conductors 45. 1n the preferred arrangements the ends of the resistance wire are wrapped around the wires 46 and the wires 46 are carried in grooves 50 formed in a body 5l of insulated material rarranged in the shank 10. The grooves 50 may be closed by a strip .52of mica or other suitable insulating material. The connections between the wires 46, carrying the ends of the resistance wire, and the flexible conductors 45 are within the handle 16 and are preferably protected or insulated, for instance, by tubes of in sulating material such as glass.

The various parts within the iron may be packed firmly in place by using a 'suitable powder or finely divided insulating material 80.

In using the device, hair is wrapped on the curler, for instance, the shank 10, or the cross-arm 11, or both, and when necessary the tie 23 is wrapped around or over the hair and the free end of the tie is secured, for instance, by the operators hand or the handle 16. lllhen it is desired to heat the curlerV a suitable electrical connection is made with or through the connector 32 so that there is flow through the resistance wire 3() causing it to become heated and thereby heat the curler.

Having described only a typical preferred form of my invention l Ydo not wish to limit myself to the details hereinbefore set forth, but wishto reserve to myself any changes that may appear to those skilled in the art or may fall within the scope of the follow` ing claims.

Having described my invention, I claim:

1. A hair curler comprising two sections arranged together to form a main part and a projection, a cap applied to the outer ends of the main part of the sections to hold them together, and a handle applied to the ends of the projecting parts of the sections to hold them together.

2. A hair curler comprising two sections arranged together and forming a shank and a cross-arm at the outer'part of the shank, caps applied te the outer ends vof the crossarm, and a handle applied to the inner endv of the shank.

3. A hair curler,comprising a hair recciving portion substantially half round in cross sectional configuration and in the form of a shank and a cross arm at the outer part of the shank.

4. A hair curler comprising a hair receiving portion, a tie and means whereby one end of the tie is slidably connected with said portion.

5. A hair curler comprising a hair receiving part having a shank and a cross-arm at the outer part of the shank, a ring carried on the shank, and a tie attached to thering.

In witness that I claim the foregoing l have hereunto subscribed my name this'24 day 4of July 1924.
