S T A T E Parser HAIR DRIER.

Application filed December 16, 1920. Serial No. 431,310.

To all whom it may concern:

Be it known that I, GEORGE J. QUALMAN, of Toledo, Lucas County, Ohio, have invented certain new and useful lmprovements in Hair Driers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form a part of this specification.

In devices for drying the hairs of women after shampoos, the chief objection,-one which precludes their general adoption,-is the expense of such devices owing to their complication and the number of parts in-- volved in their construction, including blowing fans and various kinds of heating de vices. The purpose of the present invention is to largely obviate the diiiiculty here in dicated, and, more particularly, to furnish a hair drying device which shall be exceedingly cheap and simple and by means of which an ordinary vacuum cleaner and a common coolrstove may be utilized to fur nish a regulated current or blast of warmed or heated air for hair drying purposes.

The inventive idea here outlined may find expression in a variety of forms. One illus trative embodiment of a device for attaining the advantages referred to, which I find efficient in practice, is illustrated in the accompanying drawings, in which,

Figure 1 is a top plan-view of my device; Fig. 2, a side-elevation of the same, and Fig. a sectional elevation taken on a vertical line through the regulating valve hereinafter referred to.

Like reference-characters represent like parts throughout the drawings.

lVhile in the operation of my device a blower and a heater are indispensable, they are not indicated in the drawings, for the reason that any flat topped stove will answer for the heater element, and any vacuum cleaner will serve as the blower, these structures in their various forms being well understood.

In the drawings, 1 is a vertical tubular member, open at top and bottom, composed preferably of sheet metal, and, in the present illustrative device, cylindrical in cross-section. 2 is a horizontal tubular member one end of which projects through a closely fitting opening into the part 1 near its bottom.

Thisend of the part 2 is closed except for an upwardly turned opening 13. The op posite end of the part 2 is adapted for connection, through the usual vacuum cleaner as above indicated, and that the lower end of the part 1 rests upon or as close to the top of a heated stove as may be desired.

Now, when the fan of the vacuum cleaner is i in motion, there will be a current of air through the members 1 and 2, from inlet 11 to outlet 12, as indicated by the arrows, the strength of such current being determined by the adjustment of the valve 4:. The current caused by the fan causes an induced current through the part 1 from its bottom 3 to the outlet 12, the combined currents delivering a considerable volume of warmed or heated air, which when directed through wet tresses, rapidly dries them;

Having described my invention, what I claim and desire to secure by Letters Patent of the United States, is,

1. A device of the described character, comprising an upright tubular member open at top and bottom and adapted to rest upon a stove-top, a horizontal tubular member one end of which projects into and discharges upwardly 1n the first mentioned member, the

other end being adapted for connection with the discharge opening of an air supply, and a valve in said horizontal member.

2. A structure as specified in claim 1, in combination with spring-controlled means for frictionally holding said valve in ad justed position.

3. In a hair drier, a tubular member, and a chamber into which the member projects with a discharge opening on one side and adapted to receive heated air from a stove at the opposite side of said member entrance to the chamber, said member being provided with an opening which may be placed in communication with the blower side of a source of air supply whereby the current y from the air supply causes a current of supply for drawing the heated air supply ll) mixed heated air and cool air through Said for flow through the chamber as. impelled by chamber, said flow from the tubular member.

4. A hair drier embodying a chamber In testimony whereof, I alfix my signaopen to a heated air supply, and a branch ture in presence of two Witnesses.

tubular member to said chamber, said mem- GEORGE J. QUALMAN. her being open away from the heated air Witnesses: supply to direct air flow from the heated HELEN C. WALKER,

member directly away from the heated air CATHERINE A. OHEARN.
