This invention relates to electrically operated drying apparatus for delivering blasts of heated air for face, hand and other drying purposes, such as hair, articles of apparel, etc.

Devices of this character as heretofore placed on the market, both as regards the wall and the pedestal type, are relatively large and bulky, especially in those portions containing the operative parts of the drier, such as the motor, blower and electrical heating elements. This is due to the particular design employed, which design requires the use of a relatively large outer casing to house and protect the operative parts of the drier. The nature of the support for the operative elements also requires a large bulky outer casing, all of which contribute to the expense of making these devices. This naturally controls the price at which these devices are retailed, which price is suiciently high to confine the use of these devices to oilice buildings, hotels, theaters and other public places having large and frequent attendances.

The general purpose and object of my invention is to provide a drier apparatus of such a simple and inexpensive character that the use of the drier may be extended to wash rooms and other places of more infrequent use. In other words, the main object of the invention is to provide a device of such simple design that it may be made cheaper and sold at such a low ligure that its use is made possible in wash rooms of garages, gasolene stations, small stores and restaurants, and other places where the higher price machines, because of their expense, have not been used.

In carrying out the objects of my invention, I provide outer casings for the individual blower, motor and heating units of the drier device, and connect these casings one to the other, whereby these casings provide the only outer casing required for the drier unit, thus eliminating the large outer casing heretofore required as a housing and a cover for the drier device. Moreover, I mount the drier device directly on its main support, either pedestal or bracket, by the use of trunnion-like bearing means engaging the outer casing as provided by the casings of the blower, motor and heating units intermediate the ends thereof, whereby the air discharge nozzle of the blower unit may be adjusted as required by the user on turning the blower unit in its rotative support. For balance and symmetrical appearance, I have the bearing means engage the drier device at or on opposite sides of the blower unit, the other units extending laterally outward from the blower unit on opposite sides thereof. The

arrangement described is practical, simple and inexpensive in design and construction, making a neat and compact device which by reason of its low selling price may have more or less universal use.

Specically, the bearing means referred to, as disclosed in the accompanying specification and drawings, is in the form of a yoke-shaped member having laterally spaced bearing apertures at one end for the drier unit and main support engaging means at the opposite end. These apertures are provided by annular or ring-like members which encircle the outer casing of the drier on opposite sides of the blower unit and engage cri-operating annular bearing surfaces thereon.

The invention consists further in the matters hereinafter described and claimed.

Fig. 2 is a transverse vertical sectional View taken through the blower unit on line 2-2 of Fig. 3;

Fig. 3 is a longitudinal vertical sectional view of the drier device taken on line 3-3 of Fig. 2;

Figs. 4 and 5 are horizontal sectional views taken through the pedestal on lines 4-4 and 5 5, respectively, of Fig. l;

Fig. 6 is a perspective View of one of the sections of the yoke shaped support heretofore referred to and Fig. 7 is a perspective view of the outer casing for the heating unit.

In the drawings, the main support for the drier is in the form of a pedestal, which as shown in Fig. 1, has an upright column l and a relatively Wide supporting base 2 at its lower end. The column and the base may have the conguration desired for ornamental purposes and serve to support the drier above the floor of a wash room at the height desired for convenient and ready use. The column is hollow to accommodate the electric wires or conductors which connect the main switch in the base 2 with the motor and the heating units of the drier. These wires are shown at 3, 3 in Figs. 2 and 3. The switch (not shown) in the base has an operable foot pedal 4 mounted on the base and extending outwardly therefrom through a slot, as shown in Fig. 5.

The drier comprises connected blower, motor and heating units A, B and C arranged above the upper end of the column l and connected therewith by a yoke shaped supporting member to be hereinafter described. The units are preferably connected in axial alinement and are arranged with the blower unit between the other two.

The blower unit A, as shown in Figs. 2 and 3, comprises an outer casing and a bladed air forcing member or fan (i. The casing 5 provides a housing for the fan, the latter being located in eccentric relation in the housing as in centrifugal blowers of this type. The air discharge nozzle i for the blower is on the front side of the housing in tangential relation to the fan and extending outwardly from the housing as shown in Fig. 2. The outer or discharge end of the nozzle may be covered by a protective screen S, as shown in this figure. Casing 5 and the nozzle i are integral, being preferably made of two sheet metal stampingantted together by a lock seam along their meeting edges. One section is provided with an air intake opening 9 for the blower about the axis of the fan i3.

The motor unit B comprises a universal electric motor i@ of the desired small size and power. Said motor is supported in a cup shaped case il extending into the adjacent section of the blower case 5 through an opening i2 therein. The case i i is provided at this opening with a surrounding marginal flange i3 which by screws i4 is secured to the wall of the blower case about the opening. The motor is thus supported from the blower case and has its armature shaft i5 in line with and extending into the hub of the fan and directly secured thereto.

The heating unit C comprises an outer casing i@ disposed opposite the air intake opening i3 of the blower. A suitable electric heater is located in the casing l@ to heat the air drawn into the same by the blower. Casing i@ has an air intake opening il on its under side for this purpose. A protective screen i8 covers this opening as shown. The electric heater, in the form shown in the drawings, comprises an insulating support in the form of a spider i9 about which is wound a resistance wire E@ in coiled form.

The yoke shaped support for the drier comprises a two part casting divided longitudinally to have similarly shaped half sections, each having a base portion 22 to nt against the upper end of the column i on the outer side thereof, an upright arm portion 23 and an annular bearing portion or ring-like member 24 at the upper end of the arm. The base portions 22 are at the lower ends of the arms and when placed together provide a socket to engage about the upper end of the column i. Bolts or screws 25 clamp the column in the socket, as shown.

The arms 23 are laterally spaced and receive the blower unit A between them, the bearing members 24 cn the arms being on opposite sides of the blower casing 5 as shown. With the other units of the drier on opposite sides of the blower unit, the motor and the heating units are on the outer sides of the arms, the outer casings i6 and 26 of said units extending through the bearing apertures as provided by the ring-like members 25 on said arms. These apertures are in axial alinement and have diameters slightly greater than the outside diameters of the casings which extend through them to receive collars 21, 2l, secured to the outer casing 5 of the blower unit on opposite sides thereof.

The collars 2 are secured to the blower casing 5 about the openings 9 and l2 therein and extend into and through the bearing members 24. The bearing members 24 encircle and engage the collars to rotatably mount the drier on the arms 23, whereby the nozzle 'I of the drier may be adjusted up and down on turning the drier in the arms. The t between the collars and the arms is suliiciently tight to frictionally hold the nozzle in its various positions of adjustment.

The collar for the heating unit extends beyond its bearing member 2li and is secured, as by screws 28, to the outer casing iii of that unit. The collar for the motor unit also projects beyond its support 24 and is secured by screws Z9 to the outer casing 26 of that unit. For convenience of manufacture and assembling, the casings iii and 26 extend into and overlap their respective collars 2l. Both collars are fianged on their inner sides to overlap the blower casing for support and con-` nection therewith. The flange 3G on one collar is secured by screws Si to the blower casing. The iiange 32 on the other collar is secured to said casing by the screws l heretofore referred to.

The arms 23 are preferably made hollow to provide passageways 33 for the electric conductors 3 which lead to the terminals of the motor if! and the heating element I, respectively. The collars 2l and the casing I6 and 26 have openings 34, 35 which register with each other and with the passage-ways 3% in the associated arms. These open` ings are in the form of slots elongated in the direction of rotation of the collars to avoid shearing of the conduits in the adjustment of the drier.

A suitable stop arrangement may be provided for limiting the upward swing of the nozzle, the latter contracting with the base portions fifi of the yole shaped support to limit the downward swing. For the upward swing, I may provide co-operating stop lugs (it, 3? on the support and blower casing, respectively, as indicated in Fig. 2. The base 2 may be fastened to a floor to permanently secure the drier device at its place of use. For this purpose the base has holes 3g foi` the fastening bolts or screws.

With the rotative support for the drier encircling and engaging it on opposite sides of the blower casing, as herein shown and described, the drier may be made with its various units in axial alinement and mounted directly on the main support without the need of an outer cover or housing as heretofore employed. The outer casings of the drier units provide the protection and support required for the operative parts of such units. The construction is oi such a simple and practical design that the manufacturing costs are so reduced that the devices may be retailed at prices low enough to make their use more or less universal. The construction is sturdy and strong and capable of withstanding hard use. The bearing members 2li and the co-operating bearing surfaces therefor on the drier as provided by the collars 2 have continuous engagement about the drier axis and provide an adequate pivotal support or mounting for the drier assembly. The nozzle may be adjusted to suit the requirements of the persons using the device and is heid in its adjusted position by the frictional engagement between the bearing surfaces of the mounting, which surfaces are mad-e wide enough for the purpose. Moreover, the mounting being of trunnion-like form, provides a sirnple and direct connection for the drier or at least the blower unit with the main support of the device. The trunnion formation enables the mounting to engage the outer casing of the drier intermediate the ends thereof and on the outer side of its outer casing, thus enabling a direct connection to be made between the drier and its main support and doing away with an extra housing or casing for the drier unit.

The details of construction and arrangement of parts herein described and shown may be variously changed and modified without departing from the spirit and scope of my invention except as pointed out in the appended claims.
