To (ZZZ 10.7mm it may cmwern:
Be it imown that 1, Seminar, M. Corrmin, a citizen orflthe United States, residing at Kansas @ity, in the county ol aclrson and State of Missouri; have invented certain new and useiul Improvements in Electric Hair- Drying Devices, of-which the iollowing is a specification.
My invention relates to'hair drying devices and while'it may be used to advantage for a variety of purposes, it is intended more particularly for use in barber shops for directing a blast of either relatively hot or relatively cold air against the head for the purpose of drying the hair after a sham- P i i In the accompanying drawing which shows the preferred embodiment oi' the in vent-ion, Figure 1 is a side elevation of the device.
Fig. 2 is a plan view of the device. Fig. 3 is aninverted plan viewoi the device. y
Fig. is a longitudinal sectional view of the device.
Fig. 5 is a detail inverted cross section on line V- V of Fig. 1.
in carrying out the invention l employ a chamber 1 having a removable cap 2, so that access may be readily had to the interior of said chamber 1. The cap 2 is provided with y a perforated front wall l for the passage of therethrough, and is held in position by a pin and a bayonet-slot 6 and 8 respectively. The rear wall 10 of the chamber 1 is provided with a number of equally spaced openings 12 for the passage of 'air therethrough. The rear wall 10 is also provided with a tubular handle 14- having a vulcanized rubber or other suitable grip 16, removably held in place by a transverse screw 18.
designates a plate fitting against the rear wall 10 and provided with a sleeve 22 roclrably mounted upon the handle l l, and having a thumb-piece 23 whereby it may be actuated. The plate 20 is provided with equally spaced openings 24, which register with the openings 12 in the rear wall of the chamber 1 when said plate 20 is rocked to one position. fix ire cloth 26 or perforated plates are arranged within the openings 2% the plate the openings 2%, as disclosed on Fig. 3. The
ro naitenns y to prevent obstructions from being drawn therein by theair blast created by a fan 28 mounted within the chamber 1.
3O designates plurality of ducts fined' to 20 and alternately arranged with outer ends of the ducts 30, like the openings 24:, are provided with wire cloth 32 or perforated plates.
The ducts are provided with electric heating coils 34, preierably, connected in series, the firstcoilin the series being connected to a circuit wire 36 which isconnected to a contact 37 adapted to slidably engage a contact .39 connected to a circuit wire 40, while the last coil in the series is connected to a circuit wire 42. The circuit wires are insulated and the free ends of the circuit wires i0 and 1-2 are connected to a plug (not shown) which may be insert ed in the socket of an incandescent lamp, or other device connected to a sour'ceof electricity. The contacts 37 and 39 are mounted on a duct 30 and the chamber 1, respectively, and the contact 37 also acts as an indicator to coact with the inscriptions Cold and Hot on the chamber 1. A guard is fixed to the chamber 1 to prevent the operators fingers from touching the contacts 37 and 39 and receiving a shock when the current is on.
The fan 28 is fixedly mounted upon shaft journaled in the handle 14 and having a hollow slotted terminal 16, so that it may be readily connected to a flexible shaft driven by an electric or other suitable motor (not shown). The shaft id is provided with a peripheral groove l6 to receive the invcidence with the openings 12, so that as the air is drawn through said ducts by the fan 28 it becomesheated in its passage by contact with the coils 3&. If maximum heat is not desired the plate 20 is adjusted until the openings 24 and the ducts 30 both communi-- cate with the openings 12, so that the fan 28 will draw both cold and heated air into the chamber 1 and force it out through the perforated wall l. As disclosed by Figs. 1 to 3, i
inclusive, the circuit closer contact 39 is of sufiicient length to remain in engagement with the contact 37 until the plate 20 is adjusted to bring the openings 24 fully into coincidence with the openings 12, when said contact 37 passes out of engagement with the companion contact and interrupts the circuit to the coils 34.
While I have shown and described the preferred embodiment of the invention, I re serve the right to make such changes in the construction, combination and arrangement ducts communicatinguwith said chamber to a of parts as properly fall within the spirit and scopeof the claims.v
