' ELECTRIC HAIR CUR'LER.

Application filed January 9, 1924';

To all whom it may concern:

Be it known that I, Josnrrr J. Manson, a States, residing at Tacoma, in the county of Pierceand State of Washington, have invented certain new.

and useful Improvements in Electric Hair Curlers, of which the following is a specification.

' This invention relates to an improvement in apparatus for curling the hair and has as its primary object to provide an apparatus be conveniently employed and by the emloyment of which the hair maybe Cir more quickly curled and with minimum inconvenience to the person being treated.

Another object of the invention is to provide an apparatus which may embody any desired number of curling units about which the strands of hair may be Wound and which units may be electrically connected in series or parallel and current supplied to all of the units from a source of current supply, eachunit embodying a resistance element whereby the unit will be heated to a suitable degree of temperature when current is supplied theret0.-

Another object of the invention is to provide a curling unit extremely simple in its construction and about which the hair to be curled may be readily wound, the unit embodying means for holding the hair in its wound condition and likewise embodying means for protecting the scalp of the person whose hair is being curled, from being burned or heated to a degree'to cause annoyance or inconvenience.

' In the accompanying drawing:

Figure 1 is a perspective view illustrating a hair curling apparatus embodying the invention;

Figure 2 is a detail plan view of one of the curling units;

Figure 3 is a vertical longitudinal sectional view on'the line 3-3 of Figure 2;

Figure 4 is a similar view on the line 4 4: of Figure 2 looking in the direction indicated by the arrows.

The apparatus embodying the invention comprises a plurality of hair curling units which are of counterpart construction and any desired number of which may be employed. Each of the curling units comprises a sleeve 1 of'insulating material such, as fiber, and it is about this sleeve and another sleeve to be presently described that, the hair is to be wound, the

Serial no. 685,285.

sleeve serving also to house the electrical resistance 'member of the unit indicated in general by the prises a coiled length of resistance wire, indicated by the numeral 3, which is housed within the sleeve 1 and has its ends con nected to the terminals 4, the terminals being frictionally fitted into the ends of the sleeve 1 and having projecting portions 5 onto which may be fitted collars or similar terminals indicated by the numeral 6 and connected with flexible conductor wires 7' two of which lead from any suitable source of electrical supply,- other terminals corresponding to the terminals 6 being connected electrically at the ends of short conductor wires 8 so that a number of the units may be electrically connected ina series or in parallel.

Tn order that heatmay be more readily conducted from the resistance 3 to the hair to be curled, a sleeve 9 of metal is frictionally ,fitted onto the insulating sleeve 1 and is. of substantially the same length as the said sleeve 1. The numeral 10 indicates in general a clamp member which is associated with the heating device just described, and this clamp member comprises a clamping finger 11 which is of arcuate form in cross section and is united at one end to the intermediate portion of a clip 13 which is designed to embrace the tube or sleeve 9 and, for a purpose to be presently explained, is provided at the lower ends of its' side portions with outwardly turned lips 14. At this point it will be evident that after the ends of the hairs have been disposed against the sleeve 9, the clip 13 may be applied to the said sleeve so that the clamping finger 11 will'embrace and extend over the hair ends and secure the same in such a manner as to permit of ready manipulation of the assembled parts to windthehair thereon.

A shield, indicated in general by the numeral 15, is associated'with the heating device above described, and comprises an oblong strip of insulating material, preferably fiber, which is formed with a longitudinal slot 16 thereby providing spaced fingers 17 and a connecting portion 18. Secured to the upper side of the strip at the end thereof at which the connecting portion '18 is located, is a clip 19 into which may be fitted the end or the sleeve 9 which is opposite the end to which the clip 13 is applied. In assembling the heating device with the shield, and at numeral 2. This unit comthe time of inserting the said end of the sleeve 9 into the clip 19, the lower portions of the side members of the clip 13 will rest upon the fingers 17 of the said shield, and the sleeve 9 will be held in position by the frictibnal contact "of the clip 19 and the pres sure of the fingers 17 theofingers being preferably cut away or beveled at their free ends and along their inner edges as indicated by the numeral 20 so as to permit of the more ready engagement of the said portions of the c 13 with the fingers. It will be evident at his point that after the hair has been woind about the heating device, the said heating device may be mounted upon the shield 15 in position extending longitudinally of the slot 16 to prevent unwinding of the hair.- The terminals 6 may then be fitted, onto the terminals 4 of the resistance eleand then to the ment, and when the current is turned on, the resistance element will become heated and the heat will be transferred to the sleeve 9 hair ,which, is wound about this sleeve.

26 'One advantage presented by the device embodying the ir venti-on resides in the fact that the hair may be, more rapidly treated to impart a curl thereto than by'ordinary devices, and thereis no likelihood of burning the hair or causing inconvenience to the person whose hair is being curled. Furthermore, by the use ofthe device embodying the invention, it is possible to employ the same afterthe hair has been moistened so derstoo'd, of course,

that a more permanent curl can be imparted to the hair than by the use of the ordinary devices. Likewise by roviding the shield 15, heat will not be transmitted to the scalp to a degree to cause annoyance, and yet the hair may be dried to the roots, if it has previously been moistenech It will be unthat any desired number of the curling units may be employed ,a'nd that after the units have been suitably arranged upon the head, they may all be connected in series or in p-ardllel so that current will besupplie'dto all of them uniformly.

-what is claimed as new is:

Having thus described the invention,

hair curling unitcomprising a sleeve 'on which the hair is to be wound, an elec trical' resistance element within the slee e, an a'clam'ping member upon the sleeve for holding the hair, the said clamping member comprising a clip. removably fitted onto one end of-the sleeve, and a elampin finger. extendin from the'clip'and embracing one side of t e sleeve.

2. A hair curling unit comprising ashield of insulating material, having a clip at one end and provided with a slot extending longitudinally thereof from'the said clip, a

be wound, the

gitudinally thereof from the said clip, a,

sleeve on which the hair is to be wound, the sleei-e'being frictionally fitted into the said clip at one end, a clip upon the sleeve at the other end thereof engageable with the said insulating shield, a clamping member eX- tcnding from the last embracing one side electrical resistance sleeve.

4. A hair curler comprising a hair engaging and curling element including a heating element, a shield extending longitudinally of said hair engaging element and extending beyond-opposite sides thereof, securing means carried by said shield to engage one end portion of said element and releasably hold the shield in operative relation to the hair engaging element, and a hair clamping member extending longitudinally of said hair engaging element and including securing means adapted to releasably engage the of the sleeve, and an element within the hair engaging element at the opposite end thereof from securing means carried by said shield. I a

5. A hair curler comprising an elongated shield, a fastener carried by one end portion of said shield, a hair engaging element adapted tobe disposed longitudin'a of said shield with one end portion'engaged by said shield, a heating unit for said hair engaging element, and a hair clamp adapted to be disposed longitudinally of the hair engaging element and releasably grip the same at the opposite end thereof from the fastener carried by said shield;
