Application filed June 17, 1908. Serial No. [9,063

To all whom it may concern:

Be it known that l, CHARLES W. WrLMo'r, a citizen of the United States, residing at Redondo, in the county of Los Angeles and State of California, have invented new and useful -lmprovements in Electric Curlinglrons, of which the following is a specifica- Y tion.

This invention relates to electrical or electrically heated curling irons, and it has for its object to provide an improved device,h or improved apparatus, ada ted for curling human hair, which will be re atively simple and inexpensive in construction, positive, speedy and effective in o eration, convenient in use, economical wit respect to heat units consumed., which may be subjected to continued use Without material deterioration, and which will be generali)T superior in point of eiciency.

The invention consists in the novel and useful provision, construction, combination, association and relative i arrangement of parts, members and features all as hereinafter described, disclosed in the accompanying drawing, and finally pointed out in claims.

ln the drawings-Figure l is a top plan view ofa curlingliron constructed according' to the invention; Fig. 2 is a longitudinal sidev view of the same; Fig. 3 is a composite lon-- gitudinal sectional view of the same, taken upon the lines 3ft-3a, and 3b-3b, F ig. 2, the section upon the lines 3b-3b being 'shortened to conform with the remainder of the showing; this view being presented to disclose, particularly, the electrical circuit supplying energy to the heat generating means;

ig. l is an enlarged, detail longitudinal sectional view,'corresponding to a portion of the showing in Fig. 3; Fig. 5 is a detail transverse sectional view, taken upon the line 5-5, Jliig. 2, and looking in the direction of the appended arrows; and Fig. 6 is a detail transverse sectional view, taken upon the line '--6, Fig. 3, and looking in the direction of the appended arrows.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring with particularity to the drawing, the improved electrical curling iron, which is illustrated of the type employed customarily for waving human hair, comprises two relatively movable members A and B, res ectively, between which the hair is 'receiveo and compressed in the curling operation. The heating irons a are prefer'- ably three in number, the member A comprising two, and the member B one of the same. Said members A and Bare relatively movably connected, preferably pivotally, as at l); and each of the same is provided with a grip or handle member o and d, respectively. The handle member e is provided with, and incloses electricity supply means e, whereby the heating irons are heated through the agency of resistance meansf with which each of the irons proper is provided. Each of the arms proper is detachably connected, as at g, with its respective grip or handle member c or d; whereby said arms proper, with their re spective resistance means f; may be `replaced when required by long service, or may be removed and repaired. The detachable connection at g, in each instance, is the same, thereby making the irons ro er a interchangeable. Associated wit t e members A and B, and the heating irons a thereof is a shield or apron 72., which serves to hold the hair in proper connection with the, heating irons a during the curling or waving operation.

The particular preferred form of provision, construction, combination, association and relative arrangement of parts, members and features embodyin the invention, such as in general described a ove, is as follows:

The member A is substantially of straight formation, two divergent socket pieces 7 springing from the outer end portion 8 of the grip or handle member c thereof. With each of said socket pieces 7 one ofthe irons a is detachably connected as at g. inward of the socket pieces 7 the grip or handle member c is enlarged, as at 9 to provide a firm main grip for the hand of the user of the device g said main grip 9 being preferably detachable, as at 10, by a slip joint, from the portion provided with the socket pieces 7 and having an inner detachable end cap ii having a slip joint connection, as at l2, with the main portion of said grip 9. Line wires, i3 and 14, respectively, extend through the grip or handle member c, which is of tubular or hollow formation, and throughv the socket pieces 7, said line wires being cut to inciude the resistance means f of each of the heating irons a; and said line wires 13 and 11i are connected with binding postsvl, within the grip` supply wires, 2e and 26, respectively, which. W are properly insulated andetwisted together,

f adapted toreceive respectively, in electrical engagement, contact plates 1.9 and 20, respejetivelupon a plug member lc carried the detachable end cap 11, and coninsulating body 2-1, suitably se- @tired thecap 11 as by a transverse piu 22. Electrically connected With the respective contactplates 19 and 20 by means oi screivs 23 and 24, are insulated il? preferred, to form a customary braided cord connection between a suitable source of eleehical supply and the electrical curling iron. Seidsupply wires 25 and 26 enter the il through a suitable end perforation 27` The plug memberc closes a circuit through su ply wires 25 and 26, the spring jacks i? an and the line Wires 18 and 14, through the-'agency of the contact plates 19 mm2@t thereon when the end cap 1 l 1s slipped over the inner end portion of the main grip 9 constituting the grip or handle member c.

The member'B, which carries or comprises one of the heating irons a in such position that it may be paed between or intermediste of the two relatively separated heating irons er of the member A, com rises an angular central seat portion 28, which is pivotally connected with the outer end .portion 8 of the gi or handle member c, intermediate ofthe ses *et pieces 7, as at 29, whereby the grip or handle member d normally extends beneath parailel with the grip or handle member e, the heating iron a of the member B normally lies in a'plane beneath the plane which hiehrdes the irons proper a of the membei: u The pivotal connection at 29, or b, may' he of any suitable nature, as by a pin 30.

The gp or handle membe'r is preferably et or bowed formation, open to the reception of r t; ofthe user of the device, andthe grip o- 1 idle member c may be provided with a combined guard and locking means l, consisting o a'. looped central porn'en 31, and end portion 32 encircling the Standen opposite open end portion 33 detaf bly connected with, or adapted for detachable connection with the outer end dition 8- of the grip or handle member c, as

y a 34. When the end portion 33 is the portion 8 of the lp or handle c, the parts 8 and 9 of the latter are eely held together in operative conmation.

Each of the heatin irons a consists of a preiersbly metallic tu e 35, having a closed the member B, at the outer extremity of the central angular portion28. Each of said tube/$35 is provided With an inner insulating lining 88; and disposed centrally. thereof, longitudinally of each of said tubes 35 is an 'eirteriorly insulated conducting steni or rod 39, fixed to an insulating plug 40 which closes the inner end portion of the tube 35.

Coiled about the stem or rod 39, and connected withl theouter end thereof, is a length of resistance Wire 41, the inner end portion ol' which pro'ects through the plug 40 and connects with an annular contact plate 42, seated in the face of the plug 41 opposite to that from which projects the stem or rod 39. Said stemsoi" rod 39 may also be of resistance material, if desired; and is provided with a contact Ahead 4 3 which connects with the inner end portion thereof and projects beyond the face of the plug 4() which carries the contact plate 42. Each socket piece 7, other- Wise open, is closed at its outer end portion by aninsulating plug 44, provided at its outer facefwith an annular contact late arranged to register With the annu ar contact plate 42,; `and extending through said lug 44 is a' contact head 46 arranged to reglster With the contact head 43. The line wires 13 and 14 are connected with the annular contact plate `45 and with the contact heads 46, in multiple, being looped throu h the socket pieces 7, and extending into t e intermediate socket piece 7 through an opening 48 therein from openingsl 49 in the other socket pieces.

The shield or apron h extends longitudinally of and above ,the heating irons a, being looped over the same, and centrally connected longitudinally, as at 50, with the upper portion of the intermediate heating iron a.

The operation, method of use and advantages constituting the invention Will be readily understood from the foregoing taken in connection With-the following statement: With the parts all assembled as shown in the drawing, a closed electrical circuit will ex tend through the supply Wires 25 and 26, the contact plates 19 ,and.20, the spring jacks 17 and 18, the line Wires13 and 14', the annular contact plates 42 and 45 and the contact heads 43 and' 46, and through the resistance Wires 41 and connecting stems or rods 39; and the resistance Wires 41, as Well as the stems or rods 39 if they be of resistance inaterial, will transform the electrical energy into heat within each and all of the heating irons a. When the latter are suitably heated, the hair of the user is passed about the heating irons a preferably over the exterior ones, under the guard h, and under they# intermediate heating iron c. The members A and Bare then manipulated, by means of the grip or handle members c and d, so as`to press and Wave or curl the hair. The detachable connection of the heating irons a,

sired, and substitution of fresh parts after long use and 'consequent deterioration, such asb'urningout. This detachable feature renders repair of the heating irons Withcon venienc'e-7 and is' anessential feature of the invention. The detachable connection of the parts of the grip or handle member d,'as at 1,0 and 12, also permits convenient repair and assembling of the electricity supply means vtand the plug member 7c.

Theentire device is compact in form, and may be modified With resp'ectto design and arrangement of parts to meet particular' conditions of service. I therefore do not desire to be understood as limiting myself to the specific construction, provision, combination, vassociation, and relative arrangement of parts, members and features shown and described but reserve the right to vary the conditions of use Without departing from the spirit of the invention, or the terms of the following claims.l 4
