Claims. (Cl. 219-39) v This invention relates to hair drying apparatus suchas is used in beauty parlors for the drying of human hair. In devices of this character, the hair drying apparatus is usually mounted in a hood which in turn is movably mounted so that it can be ad- Justed up and down and angularly to be placed upon the head of the customer. Devices of this character have been made with the hood ad- Justable and with hand or customer controlled heating elements so that the customer may adjust the heating effect of the drier. However, such devices, as heretofore known, have necessitated the use of auxiliary cords or control lines which may lead to the customers chair or be free so as to be placed in the customers lap. Such devices are not satisfactory because of the loose cords lying around, and hence it is one purpose of the present invention to improve the control of such devices as hair drying hoods so that the customer may set the heating elements in the hood to any desired rate of heating.

I will describe the preferred form of my invention by reference to the accompanying .drawing wherein Fig. 1 is a view in side elevation of a hair drier with the hood of the hairdrier shown in section; Fig. 2 is a sectional view taken through the hood substantially on the line 22 of Fig. 1;

0 Fig. 3 is a wiring diagram showing the electrical circuit for the fan and heating elements within the hood;

Fig. 4 is a sectional view substantially on the line 4-4 of Fig. 1.

5 Referring now in detail to the drawing, the

present hair drier is mounted upon a base I having a standard 8 in which a hood carrying stem I is vertically adjustable, the stem 1 being secured in any desired position by a suitable lock- 0 ing means such as a set screw i having a wing head 8 thereon. A hood II is mounted on the stem 1 by means: of a pivot pin II. The hood I0 is provided with a horizontally extending arm I! which is secured directly to the hood in any suit- 15 able manner and which is constructed of an inverted U-shapcd metal strip as indicated by Fig. 4. The pivot point i I is close to the hood in order that the angle of the hood I may be adjusted through a considerable range without much 50 change in the elevation thereof. This also makes the hood easier to balance.

In order to balance the hood, the free end of the arm I2 h weighted by means of a heavy filler 93 which may be of lead so as to counterbalance theweightoitbchood. Tbelcngtboftbearm I2 is preferably such that the weight it does not extend farther out from the stem 3 than the supporting base 5. This is done in order to insure stability and to prevent the device from readily tipping over. 5 As shown, the hood I0 is a sheet metal hood having an inturned rim H at its open end. Within the hood adjacent the top thereof, a bracket i5 is riveted or otherwise secured in place, and this bracket carries a fan motor 16. The fan 10 motor has a shaft H which carries a fan It. The fan It is of the disk type which receives the air by drawing it in axially to its center and by discharging the same radially outward. Below the fan 18, a plurality of brackets l9 fixed to the hood l0 support a screen til which prevents hairs from being drawn from the head of the customer into the fan I 8. A heating unit is supported between the screen and the fan It. This heating unit comprises a pair of brackets 2! and 22 20 (see Fig. 2) which brackets carry three

heating coils

23, 24, and 25. Thus the air as it is drawn from the head of the customer passes across the heating coils and to the fan l8 which discharges it radially outward so as to cause it to again be 25 circulated through the hair.

Referring now to Figs. 1 and 3, it will be noted that in the top of the hood l0 there is a bracket 2' which supports a mercury switch 21 that is adapted to turn oif the current supplied to the motor andheating coils when the hood is tipped back into inoperative position. I'his may, of course, be done readily by pressing down on the free end of the arm ii. In addition, as shown by Figs. 2 and 3, each

heating coil

23, 24, and 25 is individually controlled by a switch. The coil 23, is controlled by a switch 28. The coil 24 is controlled by a switch 29, and the coil 25 is controlled by a switch 30. These switches are ordinary snap switches having toggle handles such 40 as II. The

switches

28, 29, and 30 are so set that'the handles 3| thereof are moved up and down, that is lengthwise of the hood, to turn the current on or oil to the several heaters. 4 The onor off position may be the up position of the handle as this is relatively immaterial. However, it is important that the handles 31 move up and down and that they are all set to operate in the same direction. Preferably, they are so constructed that, when they are in the up position, the current is on, and, when they are in the down position, the current is oil. This makes it very convenient for the customer to control the heating units without making mistakes and it makes it unnecessary to have any loose cords or wires around the apparatus other than the single cord which connects the device to a source of current, and this may be connected to the stand or hood in such a way as to be out of the way of the customer.

From the above description, it is believed that the construction and operation of this device will be readily apparent to those skilled in this art. It is also believed to be obvious that various minor modifications may be made without de-,

parting from the scope of the invention as defined by the claims.

Having thus described one specific form of my invention, what I claim as new and desire to secure by Letters Patent is: A

l. A hair drier of the character described comprising a supporting stand, a hood adjustably carried thereby, air heating means associated with said hood and comprising electrical heating elements, control switch mechanism for said heating elements mounted on the rim of said hood adjacent the head receiving portion thereof, said switch mechanism having handles movable lengthwise of the hood for controlling the current supplied to said heating elements.
