HULDA E. MIKAELSON, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO ANDERS NELSON, OF CHICAGO, ILLINOIS.

HAIR-CURLING DEVICE.

Application filed May '7, 1923. Serial No. 637,064.

To all whom t may concern.'

Be it known that I, HULDA E. MinAnLsoN, a citizen of the United States, and a resident of the city of Chica-go, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hair- Curling Devices, of whic-h the following is a specification.

This invention relates to hair curling devices and has for its object the provision of al device of this character including rollers adapted to be disposed on opposite sides of a strand of hair and having intermeshing portions adapted when heated to impart a wave or undulation to the strand of hair.

Another object of the invention isi to provide mechanism to be used in conjunction with said rollers and so arranged as to impart a step b v step movement to said rollers along the strand of hair.

Still another object of the invention is to provide means for moving the rollers apart for the purpose of placing a strand of hair therebetween, said rollers being normally resiliently pressed Vto engaging position.

And still another object of the invention is to provide electrical means for heating the rollers at all times and in various positions.

Other objects will appear hereinafter.

The invent-ion consists in the combinations and arrangements of partsI hereinafter described and claimed. v j

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is a top` plan view of the invent-ion;

Fig. 2 is a side elevation of the invention;

Fig. 3 is a fragmentary side elevation of the invent-ion viewing the same from the side opposite to that shown in Fig. 2, the operating levers being' shown in their normal closed position in full lines, and in their spread position in dotted lines;

Fig. 4 is a view partially in sec-tion on the line 4 4 of Fig. 1, parts of the device being broke-n away to more clearly disc-lose the arrangement of the same;

Fig. 5 is an enlarged sectional view on the line of Fig. 1, showing the arrangement of the means for heating the rollers;

Fig. 6 is a view partly in section on the line 6-6 of Fig. 5; and

Fig. 7 is a sectional view on the line 7-7 of Fig. 4. Y

Referring to the drawings, 8 and 9 represent opposite-ly disposed curved levers pivotally connected together at 10, the lever 8 being provided with a handle 8. Pivotally connected to the outer end of the lever 8, as shown at 1S, is a. guide member 14, which guide member is provided with an open slot l5 at its outer end. Pivotally mounted adjacent the outer end of the lever 9 as shown at 16, is a. guide member 17 having turned. portions 18 adapted to fit over the side edges of the guide member 14, so that the

members

14 and 17 are mounted for sliding movement with respect to each other when the

levers

8 and 9 are operated. Gnide member 14 is provided with a stud 19, or other suitable anchoring' means, and the guide member 17 is provided with a stud 20 or other anchoring means, and resilient means, shown in the form of a spring 21, has its ends connected with the

studs

19 and 20, so that the levers are normally urged to closed position, the closing movement of said levers under the infinence of the spring 21 being limited by mea-ns of a stud 20 upon the guide member 14 which engages a cut out portion 21 on the guide member 17 so as to check such closing movement. Mounted on the guide 17 is a shaft 22, and mounted Iupon the guide 14 is a shaft ...3, andfrotatably mounted upon the

shafts

22 and 23 are rollers 24 and 25 respectively. The roller 24is provided with a plurality of'radially extending longitudinally disposed undulations or ribs 26, and the ribs 26 are preferably hollow as shown in Fig. 6. The inner end of theroller 24 is closed by means of insulating material 27, which fills the ends of ribs 26, and provides a bearing of insulating material for the inner end of the roller 24, the outer end of the roller preferably being closed by the material of which the roller is made, except for an aperture providing a bearing for engagement with the shaft, a washer l27 preferably being placed on the outer end of the shaft, together with a. nut 2S to hold the washer and roller in position on the shaft. The roller 25 is identical to roller 24 as described, so that I will employ the same numerals to designate similar parts of such rollers; however, it is here noted that the ribs 26 of the rollers 24 and 25, intermesh, and such rollers are normally held in moshing position by means of the spring 21, and when the

levers

8 and 9 are spread, the roll ers 24-and 25 tre spaced apart.

Embedded in the insulating material 27 and spaced and insulated from the shaft 22 is a metallic ring 29, and connected to said ring is one end 30 of a heating coil 31, the opposite end 32 of the heating coil 31 being connected to a larger ring` 33, embedded in t-he insulating` material 27, so as`V to be insulated from the ring 29, the insulating materialbetiveen the-ring 29 andthe shaft, and betvveen'the ring29 and the ring 33,' extending outwardly'sotas to form annular grooves at theV bottoms of which lie the rings 29 vand 33. Mounted uponthe guide member 17is a housing of insulating material 34 into Which the ends 35 of the Wires 36 extend, the ends 35 in eachfinsta-nce consisting' of an enlarged metallic head 37, Which forms a-bearing for, a spring 38, the inner end of which abuts against a collary 39" secured to a contact plunge-r 40, Whichextends through the. guide member 17, and intoengagement with the Vring 29,.the contact 33 in the housing 34being identical in construction and adaptedto engage the ring 33, allof Which features are clearly shown in Figs.` 4, 5, 6 and 7. A housing 41 onthe guide member 14, similarsto the housing 34, contains all of the-parts described for the housing 34, Which parts en-4 ergize the heatingcoil inthe roller 25;

Preferably fixed upon the insulating ma.- terial 27at the inner endof theroller 24 isa ratchet Wheel 42, and mounted on the guide 17 is a. pawl 43 heldin engaging position with the ratchet Wheel 42 bya spring 44f so as to prevent retrograde movement of the ratchet Wheel, and the roller With which it is con-V nected. Pivotally mounted upon the outer endV of the lever 9 as shown atw45, is a handle 46, such handley having ar laterally extending portion 47, to WhichV is connected a link 48 the inner end of which is provided with a hooked portion 49 which is adapt-ed to engagev the teeth of the ratchet vfheel42,l there being a bracket 50 Which engages the end ofthe link 48 toassure such engagement.v

A spring 5'1 isconnected tothe link 48 and to the lever 9- which serves tonormally return the link 48 and the handle 46 to nonengaging position. The outer end of the lever 9 is provided Wit-h a stop 52 which is adapted to limit the movement ofthe handle 4.6v and the link 48.

A housing 53 is disposed about thel rollerV 25 so as to practically cover the same and thereby prevent inadvertent contact with the hot ro-ller when the implement is in use, and a; guard member 54A is disposed adjacent t-o the inner ends of the rollers to prevent the hair coming in contact with the operating parts of the device. A comb 55 is preferably provided on the inner sides of the rollers and is shoWnAas held in position by arms 56 secured to the shaft 23, and to the guide member 14.

In operation the

handles

8 and 46 are pressed together in such a manner as to Vovercome the tension of the spring 21, this move ment serving to spread the rollers apart a suitable distance so that a strand of hair may be disposedtherebetween and spread along the lengths of the'rollers by means of the comb 55, the guard 54! preventing the hair I from comin in Vcontact with the moving parts of the c evice. Then pressure upon the handles 8 andY 46 is Vreleased the hair is held ing, through the medium of the resilient contacts 40 which remain in constant. engagement With the

rings

29 and 33, andit is pointed out that by mounting-'the contacts upon the guide members 14 and'17, the conf tact-s are .not aifectedb-y the complete spreading of therollers.

The invent-ion isV simple in construction, positive in operation andi requires a-1mi`ni' mum of. manipulation in order to.y impart an attractive wavy appearance to the hair.

While I have illustrated and describedV the preferredl form ofV construction for carrying my invention into eectf, this iscapable of, variation and modification Without-V departing' from the spirit of the invention. YI, therefore, do not Wishto be limited toy the precise details of construction set forthbut desire to avail myself of such variations and modifications as come. Within the scope of theappended claims.
