, 1 HAIR DRYER FIELD OF THE INVENTION tufts or teeth projecting from its body; the apertures I could also be disposed at the tips of these projections.
BACKGROUND OF THE INVENTION It has already been proposed to provide such imple- I I ments with conduits through which steam from a hotwater receptacle can be led to the discharge openings for treatment of the hair or the scalp of a user. Such systems, however, are not very practical inasmuch aseven with continuous electric heatingthe water supply must be renewed from time to time and the conduit from the water bath to the implement must be short to avoid premature precipitation of the steam, thereby making it difficult for the operator to handle the brush or comb. Furthermore, care must be taken in the application of steam to a persons head in order to prevent scalding; steam, in any event, is not a suitable drying agent for hair that has been wetted.
OBJECT OF THE INVENTION The general object of my present invention, therefore, is to provide an improved system for drying hair, advantageously during stroking with a brush or a comb.
A more particular object is to provide means in such a system for effectively controlling the temperature to which the hair to be dried is subjected.
I SUMMARY OF THE INVENTION I realize these objects, in accordance with my present invention, by the provision of a source of hot air under pressure connected through a flexible conduit to the hollow body of the apertured implement which is to come into contact with the users hair.
According to a more particular feature of my invention, the source of hot air comprises an impeller such as a fan for generating an airflow and an air heater in cascade with the impeller. The air heater and the impeller are provided with respective controls for adjusting the heat output and the flow rate in order to provide an air stream of desired temperature and intensity. If the operator wishes to change that intensity, he may do so by adjusting the corresponding control, preferably with the aid of a floor pedal next to a customers chair in the case of a barber shop or beauty parlor equipped with such a system. In order to maintain an optimum temperature with different flow rates, another feature of my invention provides for an optional coupling between the two controls to vary the heat output in step with the fan speed so that the preselected temperature remains substantially constant.
BRIEF DESCRIPTION OF THE DRAWING The above and other features of my invention will I FIGS. 2, 3 and 4 are perspective views of various hair-grooming attachments (i.e. brushes) to be used with the unit ofFIG. 1;
FIG. 5 is a circuit diagram for the unit of FIG. 1; FIG. 6 is a perspective view of another attachment, i.e., an air nozzle, to be used with the unit of FIG. 1;
and
FIG. 7 is a somewhat diagrammatic representation of a coupling between heat andflow controls for the unit of FIG. I
SPECIFIC DESCRIPTION In FIG. I! have shown a source of hot air under pressure, comprising a generally hemispherical housing 1 with air-intake apertures 10. A heating control 4 and a' FIGS. 2, 3, 4 and 6. Heater 4 and fan 8 are adjustable, I
as described below with reference to FIG. 5 by means of a pair of control knobs 5 and 6. Housing 1 is supported on a base 21 from which an electric cord 11, provided with a foot-operated on/off switch 12, extends to a plug 14.
' I prefer to construct the housing 1 of Florentin aluminum with a baked-enamel coating which may be decoratively patterned, e. g., with a pin-stripe design. A hook 9, projecting from the housing, serves for the storage of the hose 2 in coiled-up form.
In FIG. 2 I'have shown a rotary brush with a generally frustoconical body 24 on a handle 19, the body carrying tufts l8 interspersed with discharge apertures 17 for hot air introduced through the hollow handle. The
latter has a bayonet coupling 15 complementary to hose coupling 16 whereby hot air from the interior of housing 1 (FIG. 1) can enter the body of the attachment and exit through the apertures 17.
In FIG. 3 I have shown a similar brush with an upwardly convex body25. FIG. 4 shows a flat brush body 26. The three brushes of FIGS. 2-4 may be interchangeably attached to the hose 2. In lieu of these brushes, a nozzle 20 shown in FIG. 6 may be so attached with the aid of the same kind of bayonet cou pling l5.
In FIG. 5 I have shown the fan 8 connected to supply line 11, in series with switch 12, via a potentiometer 6 controlled by knob 6' of FIG. 1. In an analogous manner, coil 4 is connected across the line via a potentiometer 5 controlled by knob 5 of FIG. 1.
With these controls 5, 5' and 6, 6' it is possible to se- Iect a suitable rate of heat generation and airflow within certain ranges. However, in many instances it will be desirable to maintain a temperature once selected even if the flow rate is to be changed. For this purpose the two potentiometers 5 and 6 may be mechanically interlinked as illustrated in FIG. 7.
Knobs 5' and 6' are shown mounted in FIG. 7 6h respective shafts 5", 6", shaft 5" being telescoped In a tubular shaft 27 which is integral with a bevel ear 32 and a sleeve 33 internally provided with teeth 37. Khfib 5' carries a button 34, urged radially outwardly by a spring 36, which is rigid with a tongue 35 extending into the sleeve 33- With button 34 released, tlifl fffl end of tongue 35 enters a groove 38 between teeth 37 so as positively to couple the knob and through it the potentiometer shaft 5" with the sleeve 33. However, a stationary cam 48 depresses the tongue 35 in an illustrated zero position in which potentiometer 5 is opencircuited so that the heating coil 4 (FlG. 5) is not energized. The several shafts are journaled in nonillustrated bearings within housing 1.
With the described coupling, the fan speed may be independently adjusted with the aid of potentiometer 6 as long as the knob 5' is in its home or zero position in which shaft 30 is decoupled from shaft 5" by the cam 48. After this initial adjustment, the operator may energize the coil 4 through the potentiometer S by turning the knob 5' while depressing the button 34 so as not to alter the previously selected setting of potentiometer 6. As the heat output from coil 4 increases, the temperature of the generated airflow rises until it reaches a desired level as indicated by a nonillustrated thermometer. If the operator thereupon releases the button 34, the two potentiometers remain coupled so that any reduction or augmentation of air speed results in a commensurate decrease or increase in heat output whereby the temperature of the air stream remains substantially constant.
In order to vary the temperature, the operator need only depress the button 34 and rotate the knob 5, leaving unchanged the setting of knob 6' and thus the flow rate of the air stream. Since this type of adjustment requires a conscious effort on the part of the operator, the risk of accidental temperature increases to uncomfortable levels is avoided.
A pedal as shown at 39 may, of course, also be used to control the heater potentiometer 5, either jointly with knob 5' or in place thereof.
