PATENT orrlcs,
' I manner enema, or NEW roux, N. r,
namwavme HEATER.
Application filed August 25, 922. Serial No. 534,447.
To all'whom it may concern;
Be it known thatLI, ERNEST UNonR, a
citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Hair-Waving Heaters, of which the followin isa specification. I I a e inventionrelates to an electrically r energized tubular heating unit for waving 7 strands of hair on a personshead and the invention specifically relates to a metal blank p from which "the frame of such unit is formed. T1- 1 i 1 6 "In previously known-'- forms v of these heaters difficulty has been experienced in avoiding the Ob ection thatthe were'cumbersome "and that their comp icated constructionto attain-the degree of heat and expensive as well as bulky. Further 3 it is vitally necessary i'ntheart of wavinghair that alarge number of these "heaters be in use at one time; Therefore'any heater unit 'havin which won d tend to 'minimizethe number of heaters which should be accommodated on the head, counts against theefiiciency such articles.
heretofore been in theform' of a relatively 0 large member and has necessarily been of some bulk to provide the necessary securv ing means to'the electric cable in those cases where the cable is passedthrough the handle. The present disclosure features.;the use of part of thepelect'ric' cable as a handle but instead of using a bulky, strain" resistant member,' the asbestoscordand the cablefirmly secured 56 to the heaterby means of a light metal J metal 7 strain rom the connection between the usual the necessary heat insulation rendered them s show internal construction; a structure or configuration and thus minimizes the commercial value of Accordingly, the a rimary object of the inventionis to provide a simplified, easily ace'ntthe persons ortion of the cable adjacent the unit is simply wrapped with a clamp which acts'to'tran'sfer pulling strains from the handle or cable directly to the ortlon of theheater and relieves heating coil in such heater units and the electric conductors contained in the cable.
Various other objects and advantages of the invention will be in part obvious from an lnspection' of the accompanying dr'aw-- ings 'and in part will be more fully set forth in the followin particular description of one form of mec anism embodying my invention, and the invention also consists in certain new and novel features of construction-and combination of parts hereinafter set forth and'claimed.
In the accompanying drawing Figure 1 is a plan view of the metal blank from which the tubular frame of'the heater is constructed;
Figure 2 is a perspective view of aheater constituting a preferred embodiment of the invention and with parts broken away to Figure 3 is a longitudinal sectional view takendaxially of the heater shown in Figure Figure 4 is 'a transverse sectional view 1 taken on the line 4-4 of Figure 3.'
In the following description and in the claims; 1 arts" will be identified by' specific names or convenience of expression but they are intended to 'be as'generic in their application to similar partsasthe art will permit. 1 I I Referring to the metal blank in Figure 1 there is'shown a single piece of thin sheet brass; having a rectangular body portion 10 from one of-the relatively long edges 11 of Whi'ch extends a projection 12 substantially rectangular in plan and connected to the body portion 10 by means'of'a constricted neck portion 13. It is understood that the body portion 10 is bent about a cylindrical form'until'the edges 14 and 15 meet and are abrazed together toform a relatively short open ended tube 16 adapted. to containall or a portion ofthe wrapped hair as is usual in the practicin of permanent hair waving such as'isdescri ed 'inthe patent to Kremer, No.'1,164,102.
The edges 17 and 18 of the extension are similarlyfbrought together-to form a tubular clamp 19 for containing the cable 20 hereinafter referred to. Opposite ends of the tube 16 are provided with outstanding flanges 21 for confining the asbestos cement hereinafter described.
' Th tube 16 is wrapped with a layer of insulating material, such as mica, shown at 22 and this in turn is wrapped with a coil of heating wire 23 all as is usual in similar constructions now known. The wire is wrapped with a layer of asbestos cord 24 and this in turn is embedded in a layer of insulating cement 25 preferably of a character of cement which becomes hard when baked and which will form the outer protected surface to the heater. The cable 20 for supplying lectric current to the heater is passed through the clamp 19 which has its free edges 17, 18 pressed into-the cable so as to securely fasten the same to the tube 16. In this way any pull on the cable is transferred directly to the tube 16. The cable is provided with conductors 27 which are connected electrically to the free end of the heating wire 23 by spot welding 28. By this construction it is noted that the C011- ductors in the cable are securely attached to the coil of heating wire wrapped about the tube 16 and the connections at 28 are free of any strains incidental to a pull on the cable. The cable is wrapped with asbestos cord 29 constituting an extension of the wrappings 24 and extends from the connection of the cable conductorswith the heating wire for two or three inches. along the length of the cable so as to' provide an insulating handle 30.
It was noted from Figure 3 that the handle is offset from the tubular part adapted to contain the hair for a relatively short distanc and in this way a plurality of these heaters ma be assembled on the head with any desired spacingand even with the cylindrical body portions thereof touching each other. As so constructed the heater unit is formed simply of a single sheet of metal, a sheet of mica, a wrapping of heating wire and a coating of cement, it being obvious that the refinement of adding the wrapping of asbestos'cord may be eliminated. However, it is found advisable to utilize the cord for it gives'tensile strength to the cement; it minimizes any possibility of cracking and is relatively inexpensive. The sheet metal brass herein disclosedin Fi ure 1 may be of thinner gauge than has been used heretofore, dependenc being placed upon the baked cementitious coating and the flanged ends of the tube to eliminate any tendency to distortionunder strain;-
With the device disclosed there is no need for providing means for'repairing the same for it is cheaper to cut off the cable andthrow a damaged heater away rather than make any attempt to repair the same.- The heat may be concentrated as desired in the end of the tube designed to be positioned adjacent the head simply by confining the wrappings of the heating wire adjacent the flange 21 opposite the clam 19in which case the portion of the tube a jacent the opposite end, that is the upper end of the showing in Figure 3, is free of heating wires.
While I have shown and described, and have pointed out in the annexed claims, certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made b those skilled in the art without departing rom the spirit of the the same, the edgesof the body portion 3 which extend at right angles to the edge provided with the extension contacting to complete the tube and opposite edges of said extension adapted to be bent towards eachother'to form a tubular clamp for securing therein a cable leading to the heating wire.
