- To all whom it may concern Be it known that I, GEORGE QUAL AN, a citizen of the United States, residing at T0- ledo, in the county of Lucas andState of Ohio, have invented certain new and useful Improvements in Hair-Driers; and I do declare the followingto be a full,'clear, and exact descriptionof the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to a, device for use. by women in drying their hair after washing or shampooing the same, and is intended to furnish a light, cheap, compact, simple, durable blower which may be detachably secured to the top of an ordinary stove, and by means of which a blast of heated air may be directed upon and through the hair of the operator, utilizing the heat of the fire in the stove, while avoiding bringing gases and products of combustion in contact with the air.

My invention is also designed to overcome the difiiculties encountered in devices of this character arising from the undue weight of the machine, its initial cost, and the fact that the machine must be operated by a second person. Among the advantages attained are that lamps or torches and elec tric heating devices and their connections, usually employed as air heating means, are dispensed with.

To these ends my invention consists of the devices, construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, in which Figure 1, is a side elevation of my device in operative position upon an ordinary stove, the stove being indicated in section; Fig. 2, an edge-view of the same with the fancasing, the gear-casing and the base, hereinafter referred to, in centralvertical section; Fig. 3, a side-elevation ofthe same, seen from the right in Fig. 2, with the outer side of the gear casing removed and with a portion of the fan-casing broken away to ex pose the fan, the base being shown in section, and Fig. 4:, a sectional view of the fancasing, the gear-casing, and the base, hereinafter referred to, with arrows indicating the course of the air through the device.

Specification of Letters Patent. Patented J line 10, 1919.

" Like numerals of reference indicate like parts throughout the drawings.

In the drawings,1 is the base of my device consisting of a pieceof sheet'metal pressed or stamped into saucer shape, the downwardly turned rim of which is of sufficient circumference to surround an ordinary stove-hole. 2 is a fan-casing formed of two dish-like sheet metal stampings having their edges opposed and secured together; This caslng is provided at its upper portion with a spout 3 upon which may be slipped an out: let tubeadapted to be turned in any direction, the tube, in the present instance, being, for illustration, flexible The lower edge of the casing 2 fits closely into andprojects through an opening 5 in the top of the base 1 and extends downwardly as far as the plane of the lower edge of the base. In forming the opening 5 in the top of the base, flanges 6 are struck downwardly and these form convenient means for clasping and holding the fan-casing in place.

In the casing is a fan 7 mounted upon shaft 8 journaled at one end in one of the walls of the fan-casing and extending through an opening in the opposite wall. Fixed upon the latter end of the shaft 8 is a pinion 9 driven by a train of gears, as illustrated in Figs. 2 and 3, the final member of the train being fixed upon crank shaft 10 journaled at its inner end in the adjacent wall of the fan-casing and at its outer end in the wall of the gear-casing. This casing, 11, consists of a saucer-shaped sheet metal stamping just large enough to cover and protect the gears above referred to, the flanged edge of the gear-casing being secured to the adjacent wall of the fan-casing. Upon the outer end of the shaft 10 isremovably secured a hand-crank 1 2, the slow turning of Which will, through the train of gears, cause a rapid rotation of the fan.

In the sides of the fan-casing, as well as in the edge of the gear-casing, are openings 13 through which air is admitted to the fan, as indicated by the arrows in Fig. 4.

14 is a bar of metal secured to, the under side of the flat top of the base 1,,the free end of the bar being bent downwardly below the lower edge of the base and projecting outwardly beyond, the outer edge of the base. This bar may be secured to the base in any desired manner. In the present instance, for illustration, the bar is bent to pass through openings in thewtop of the base, as indicated in Fig: 3. Thebar 14 is under the gear-casing and extends in the direction of the plane of movement of the crank.

The base being positioned to cover a stovehole, the projecting end of the bar 14 will slip under the edge of the stove-hole and hold the machine in position while being op.-

erated. The part of the fan-casing which extends into the base is exposed to and heated by the fire in the stove, and is further heated by convection from the cavity of the base which is also exposed to the fire. Now, as the air is drawn into the fan-casing it is rapidly heated and forcibly expelled through the tube 4 to the desired point.

Having described my invention, what I 1 claim and desire to secure by Letters Patent is 1. In a device of the described character, a base having a downwardly projecting rim,

ing into its cavity, means fordriving said fan, and means'for detachablysecuring the base to the margin of such stove-hole.

2. In a device of the described character, a base having a downwardly projecting rim, the base and its rim being adapted to cover a stove-hole, means for detachably securing the base to the marginof such hole, a fancasing secured to and projecting downwardly through the top of such base, said fan-casing having inlet openings and an outlet opening, a fan in said casing, means connected with said outlet openingfor directing the air-currents therefrom, a train of gears adapted to drive said fan, a gear-casthe base and the rim being of suflicient dimenslon to cover a commonstove-hole, a

fan-casing secured to said base and project- Copies'of this patent may be obtained for five cents each, by addressing. the Commissioner of Patents,
