ELECTRIC HAIR-CURLER.
Specification of Letters Patent.
Patented Nov. 12, 1918.
YTo all whom t may concern:
Be it known that I, EDWARD SCHWAITZ, a citizen of the United States of America,
residing in the city, county, and State of New York, have invented certain new and useful Improvements in Electric Hair-Curlers, of which the Vfollowing is a specification.
My invention relates to electric hair curlers, and the object of my invention is to provide an improved construction having the advantages set forth in the following specification and claims and shown in the accompanying drawings, in which- Figure 1 is a broken side elevation of an electric hair curler in which my invention is embodied in one form;
Fig. 2 isa'side elevation of the shield;
Fig. 3l is a similar view of one of the casing tubes;
Fig. 4 is a longitudinal section through a portion of the curling iron, showing both casings in'position;
Fig, 5 is a section on the line 5)#5, Fig. 1; Fig. 6 is a transverse section on the line Fig. 7 is a schematic view of the resist- L ance element; and
Fig. 8 isiapartial perspective, drawn to a much enlarged scale, showing a portion of the resistance element.
The implement here shown is of the general type disclosed in my Patent N o. 1,033,122, but differing therefrom in certain particulars.l Thus, the handle comprises two sections 10 and 11, the former rigidly attached to the tubular casing 12 by any suitable means, such as the set screw 13, which engages the ferrule 14. As in my previous patent, the outer end of the ferrule is enlarged tov form a retaining ring 15, spaced from the casing 12 to receive the arcuate saddle 16 of thebracket 17, to which the shield 18 is pivoted at 19. The shield is held in adjusted position by the band 20 in the spring 21 taking into an annular groove22 inthe retaining ring 15,. The bend 20 is released from-the groove by a finger piece 23 at one end of the spring wire, the opposite end of which bears against the operating end of the shield on which aA button 24 is preferably secured.
It often happens that the user of the imv plement prefers to crimp or wave, rather than curl. the hair. The tubular casing 12 is ci Jo small diameter, however, to secure 55 this effect satisfactorily, and I have, therefore, in my present improved tool provided a second tubular casing 25 adapted to sleeve over the casing 12. In my preferred forni, I provide also a second guard 26 to coperate with the crimping casing 25, and for this purpose, I furnish the latter with a retaining ring 27 and ferrule 28, the latter sleeving into the retaining ring 15 in the adjusted position of the casing 25, while the saddle 29 of the guard 26 engages the annular groove in the retaining ring 27 in precisely the same way as the saddle 16 of` the guard 18 engages the retaining ring 15. In order to adjust the casing 25, it is necessary to remove the guard 18. IVhile I have indicated as my preferred construction a separate guard 26 shaped to the contour of the enlarged casing 25, it is possible to use a single guard for both casings, and for thispurpose, the smaller guard 18 may be slit at 30 along its margins to permit the latter to expand and accommodate themselves to the diameter of the casing 25,
In my previous construction, the Wire mains-31432 were directly connected to the lead wires 'of the resistance element. In my present construction, however, the end portion 11 of the handle is made detachable from the inner portion 1() and carries a terminal block 33 of insulation. To one face of the latter I secure a spring terminal 34 by a rivet 35 which holds beneath its head and in electricalA connection with the terminal 34, the -bared end of the line wire 32. On the opposite face of the block, I secure an arm 36 by means of a rivet 37, which,
in like manner, establishes electrical connection between the bared end of the Wire main 31 andthe terminal arm 36. The latter is integral with a ring terminal 38,
and the free end of the spring terminal 34 is alined with the bore thereof. Projecting from the end of the handle portion 10 is a plug member comprising a center contact 39, the stem 40 of which passes through a pair of insulating bushings 4l-42, and is tapered at its inner end to receive a clamping nut 43, which engages the bared end of the resistance lead 44. Spaced from the ioo center Contact 39 by the bushing 41 is a' sleeve contact 45,-the inner end. of which is spaced from the clampingnut 43 by the i of considerable advantage from a practical standpoint, since it enables the user of the implement to rotate the casing l2 to wind the hair thereon without twisting the lead Wires 231-32. Furthermore, it permits this operation to be performed without the inconvenience caused by the presence of the lead wires, since the outer portion'of the handle 1l may be temporarily detached and then connected when the hair is wound in position on the tubular casing.
In implements of the present character, Which are apt to be thrown around rather carelessly or dropped upon' the dressing table,`there is considerable danger of injury to the delicate resistance wire. The latter 1s very line and quite fragile, and injury often results thereto where it is wound, as heretofore customary, upon a rigid tube of insulating material, such as porcelain, bakelite, etc. In the present construction I have provided a novel resistance element comprising a'tlexible strand, in which the resistance wire is embodied and which may be folded to the desired shape. As indicated in Figs. 7 and 8, the resistance wire 48 is spirally Wound on a core 49 of flexible insulating material, such as asbestos strands, and is then i'ncased by a spiral winding of asbestos tape 50. Inaslnuch as the strands 49 and tape 50 are relatively soft, the resistance Wire is readily embedded therein, so that the spires thereof are spaced apart and held in spaced relation by the core 49 and Wrappin 50. A strand so constructed may be dou led back upon itself, as indicated in Fig. 7, and the double strand then folded to I afford a resistance element comprising four parallel lengths of resistance coil formed from a single continuous strand. The ends of the resistance wire are connected in any way, by soldering or twisting, to the ends of the resistance leads 44 and 47, and the connection rendered secure in any suitable way,
as by embedding the same in insulating cement 5l. Fig. 7 In order to hold the four lengths in approximately fixed position, I' surround the same by retaining bands of metal 5:2, preferably sheet copper, which form good conductors of heat and transmit at these points the generated heat to the tubular easinglQ. This construction is extremely economical, from a manufacturing standpoint, and extremely durable, from the users standpoint, and forms an improvement of marked value in the implement. There is practically no danger of breakage of the resistance wires, since the soft iexible core and wrapping form a sort of protective cushion therefor, without, however, lessening in any degree the heating value of the coil.
I do not limit my invention to the precise details of construction shown, since the various features described are not necessarily interdependent, and the various details of construction may be modified in many ways without departing from what I claim as my invention.
I claim l. An electric curling iron comprising a handle, a tubular casing rigid therewith, a
resistance element within the casing, a scc-i ond ytubular casing detachably sleeving on the first casing, and a pivoted shield for said second casing.
2. An electric curling iron comprising a handle, a tubular easing rigid therewith, a resistance element within the casing,'asee -ond tubular casing detachably sleeving on the first casing, and a pivotedsshield coperating with either of said first or second casings. Y
3, An electric curling iron comprising a handle, a tubular casing rigid therewith, a resistance element within said casing, a retaining ring surrounding said casing but spaced therefrom, a detachable shield having a member engaging between. said ring. and casing and provided with means to hold the shield in position, in combination with a. second casing sleeving on said first casing and engaging between said ring and first casing.
4. An electric curling ironcomprising a handle, a tubular casing rigid therewith, a` resistance element within said casing, a second tubular casing detachably sleeving on said first casing, and shield means coperating with said first and second casings, for the purpose described.
In testimony whereof I have signed my name to this specification.
.EDWARD SCHWARTZ.
