H.- W. PEAVLER HAIR HEATER Sept. 9, 1930.

Filed March 19, 1929 Patented Sept. 9, 1930 UNITED STATES HIATT W. PEAVLER, OF, LOS ANGELES, CALIFORNIA HAIR HEATER Application filed March 19, 1929. Serial No. 348,154.

My invention'relates to a hair heater that is especially designed for use in connection with machines that are utilized for effecting what is known as a permanent wave upon hair of the human head.

My present invention is an improvement upon the visible electric hair steamer and curler set forth in my copending application for U. S. Letters Patent filed December 13th,

1 1927, Serial No. 239,633.

The principal objects of my invention, are to generally improve upon and simplify the construction of the device disclosed in my aforesaid application for patent, and to pro- 15 duce a hair heater that is relatively simple in construction, inexpensive of manufacture and which may be advantageously employed in heating strands of hair that are wound upon spindles or cores and which latter lie directly upon the head or which project outwardly or radially therefrom.

In some types of permanent hair waving machines the spindles or tubes upon which the strands of hair are curled lie directly against the head, whereas in other types of machines the spindles carrying the coiled strands of hair projecting outwardly or radially from the head and it is thepurpose of my invention to provide a convertible heater that may be readily utilized in connection with the now generally used types of permanent waving machines and which heater is constructed so that it may be easily and quick ly applied to or removed from the spindles 5 that carry the curled strands of hair.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of p parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of the main body port-ion of my improved hair heating device.

Fig. 2 is a perspective View of a detachable member that is applied to the body of the heater for the purpose of producing a tube that encloses a curled strand of hair that is carried by a spindle or tube.

Fig. 3 is an enlarged cross section taken on the line 3-3 of Fig. 1.

liig. 4 is an enlarged cross section taken on the line 4-4 of Fig. 1.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates a hollow housing or shell that is formed of suitable sheet metal and which shell or housing is substantially half round or U-shaped in cross section and formed in the outer face of the outer wall of said shell or housing, adj acent to its edges, are longitudinally disposed grooves or channels 11.

Arranged within the chamber in the housing or shell 10 and thoroughly insulated therefrom is a heating coil or element 12, and the terminals thereof being connected to conductors 13 that extend through a short tube 14, which latter projects outwardly from the 1 central portion of the shell or body 10.

Secured to the tube Hand surrounding the same is ashort handle 15, preferably formed of hard rubber or other suitable insulation and o the two parts thereof are clamped to the tube in any suitable manner, preferably by means of rivets 16 or screws. The conductors 13 lead from a suitable source of electric current supply and when the current is turned on through said conductors the heating coil or element 12 within the housing becomesheated, thus heating the walls of the shell or housing in the desired manner.

A channel-shaped member 17, preferably formed of metal and the length of which is equal to the length of the shell or housing 10, is provided on its side edges with hookshaped flanges 18, which latter are adapted to engage the side edges of the shell or housing 10 and the ends of said flanges are adapt ed to engage in the grooves 11 when the two parts of the heaterare properly assembled.

As a result of the arrangement of the grooves 11 in the shell or housing 10 and the hook-shaped flanges, it is necessary to move the two parts of the housing longitudinally with respect to each other when the same are assembled or taken apart.

The channel-shaped housing 10 is utilized for the purpose of heating a strand of hair that is wound. upon a spindle when the latter lies directly upon the head, and when the heater is thus used the shell or body is positioned directly over the coiled strand of hair, as illustrated in Fig. 3. V

lVhere the spindles with the strands of hair curled thereon project outwardly or radially from the head the channel-shaped plate 17 is positioned upon the shell or housing 10 by engaging the flanges 18 on the side edges of the shell or housing and thus a substantially tubular structure is provided, as illustrated in Fig. l, and which tubular structure entirely encloses the strand of hair that is curled upon the spindle.

In some instances it maybe found desirable to form the side edges of the shell or housing and the flanges on the channel-shaped member 17, so that said flanges may be sprung or snapped into the grooves in the shell or housing and thus the two parts of the device may be assembled without toe necessity for moving said parts longitudinally relative to each other, as herein set forth.

If desired the sliding member 17 may be formed as a housing and wired with a heating element and thus both parts of the device may be electrically heated.

Thus it will be seen that I have provided a hair heater that is especially designed for use in connection with permanent wave machines and which heater is relatively simple in construction, inexpensive of manufacture, capable of being easily and quickly assembled or taken apart and said heater being very effective in performing the functions for which itis intended.

It will be understod that minor changes in the size, form and construction of the various parts of my improved hair heater may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. In a hair heater, an inverted channelshaped housing, an electric heating element within said housing, a handle projecting from said housing and a channel-shaped member having longitudinal sliding engagement with the lower portion of said channel shaped housing and adapted to combine.

therewith to form a tube.

2. In a hair heater, an inverted channelshaped housing, an electric heating element within said housing, said housing being provided on the lower portions of its sides with grooves, and a channel-shaped member having its side edges terminating in hook-shaped flanges that are adapted to enter the grooves in said housing when said housings are moved lengthwise toward each other.

3. In a hair heater, an inverted channeL shaped housing, an electric heating element within said housing, the lower portions of the sides of said housing terminating in parallel beads, there being externally disposed grooves formed on the outer faces of the housing directly above said beads and a channel-shaped member having its side edges terminating in outwardly projecting longitudinally disposed channel-shaped flanges that are adapted to engage the beads on the lower edges of the inverted channel-shaped housing when the two housings are moved longitudinally toward each other.

e. In a hair heater, an inverted channelshaped housing, an electric heating element within said housing, the lower portions of the sides of said housing terminating in parallel beads, there being externally disposed grooves formed on the outer faces of the housing directly above said heads, a channel-shaped member having its side edges terminating in outwardly projecting longitudinally disposed channel-shaped flanges that are adapted to engage the beads on the lower edgesof the inverted channel-shaped housing when the two housings are moved longitudinally toward each other and a handle mounted on and projecting upwardly from said inverted channel-shaped housing.

In testimony whereof I affix my signature.

HIATT W. PEAVLER.
