HAIR-STBAIGHTENING, coMBQ I Hair-Straightening Combs, of which the following is a specification.

This inventionrelates to hair flattening or straightening devices in which a bar or backing having a deeply serrated or toothed edge is used and adapted to be heated and to have the combed hair taken in suitable quantities or swaths along the head of a person and drawn taut as it will stand the pull over the said bar or backing and thereby relieved of its natural or other tendency to undesirably kink or curl, and the prime object of the invention herein is to provide a longitudinal bar or backing of forged steel or the like having along one edge an integral series of parallel deep teeth that are preferably slightly convexed on their outer edges and likewise concaved on their inner edges, such bar having a rectangular cross-section and its inner end extended into a tang whereby it is secured in place in a wooden or other non-conductor handle for due manipulation in the kinky or curly hair or discomfort to the person during the treatment.

In the accompanying sheet of drawings,

Figure 1 is a perspective view of the device embodying my invention in its most approved form, and Figure 2 is a transverse sectiontaken on the dotted-line 2, 2 of Fig-.

ure 1.

3 indicates the main head-bar or bodyportion of the. device, of rectangular crosssection, and having along one side thereof.

a series of integral, parallel'teeth 4 whose outer faces 5 are somewhatcurved or convexed starting from a point 5 at the outer lower edge of the bar 3 and terminating. at the tip 5", and whose inner faces 6 slightly curve inwardly from said tip to a point 6 V Specification of Letters Patent. Patent d A Application filed February 17, v1921. Serial Not-445,773.

and then take a more direct or decided curve I 6* till :the inner, lower edge of'said bar is reached; all as best shown in Figure 2 and which structure I find has been the most pract cable for the purpose named herein. In Fig. 2 1t Wlll. be very plainly seen that the head-bar or body-portion8 is of exactly square cross-section along the respective teeth pits, whterebylfourc'1 distinct .or decided corners or rec angu ar e es are resented to the kinky hair that is td be woiind around the said head-bar several times, or at least one full turn to attain the desired degree of tension or friction thereon while the teeth are passing throughsaid hair in the flattening and straightening operation hereinafter described.

7 1s a pointed tang formed integral with the inner end of the head-bar 3 and inserted in a handle 8 of wood or other suitable nonconducting material. ferrule 9 is'placed on the tang? at the inner end of the handle.

The customary metal The head-bar, together with the integral 7 ture that will not burn or otherwise injureI- thehair or the scalp. Such material is last ing and will not be easily bent or broken in handling. In the operation ofthe device'the heated comb is set with its teeth in engagement with a swath of'the kinky or curly hair and p then turned on its longitudinal axis sothat said hairshall be wrapped or wound around the head-bar tight enough to permit a draw? mg or pulling on the kinky or curly hairs through the teeth butwith sufficient tension onthe four corners of the head-bar 3, along the lines of the respective teeth pits, to

stretch them straight along the said head v bar, the heat of the teeth somewhat drying the hair at the time and-the heat of the head-'- bar along its flat back-surfaces and angles be ng also suliiclent to make suchstretching lasting and resultlng in the desired flattened condition of the hair, entirely free jfrom kink. or curl, and to readily lie flat, as well as to comb flat with'theordinarycomb, as

the user wishes. It is preferred and desirable to use oil of a suitable nature and consistency on the hair before applying de-Q ,viceherein to make itpliable as well as form a backing or supporting-surface for the spread-out hairs When separated and Wound thereover and in contact With the said square or rectangular corners for the required drawing thereon in the direct and resultant straightening or flattening operation While the comb is in a properly heated state, and a Wooden or other suitablenonconductor handle in which the" said tang is inserted for the proper holding and manipulation of the comb in heating same as Well as in its use on the head of the person in the said treatment of curlv or kinkv hair, subbar being of square cross-section With four decidedly-square corner-edges along the line of the respective teeth pits and adapted to stantially as herein shown and described.
