Application July 21, 1934, Serial No. 736,424

3 Claims.

The invention relates to a combination hair drier and liquid sprayer.

The primary object of the invention is the provision of a device of this character, wherein lid- 5 uid for the treatment of the hair of persons can be conveniently sprayed from a receptacle and the spraying being had through air under pressure, there being a control for the motive power and for the air under pressure and this control 10 being conveniently arranged so that it can be manually operated.

Another object of the invention is the provision of a device of this character, wherein the construction thereof is novel to permit the said device to be utilized as a hair drier or a liquid sprayer for the spraying of liquids as commonly used for the treatment of the scalp and hair of a person.

A further object of the invention is the provision of a device of this character which is simple in construction, thoroughly reliable and efficient in its operation, conveniently handled, readily convertible for use as a sprayer or a drier, easy of operation, strong, durable, and inexpensive to' manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinajter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

K Figure l is a fragmentary vertical longitudinal sectional view through the device constructed in accordance with the invention and showing diagrammatically the electrical hook-up for the same.

Figure 2 is a side elevation partly in section of a nozzle used when the device is employed as a hair drier.

Figure 3 is a side elevation partly in section of the motor and fan'employedwith the device.

Figure 4 is a vertical transverse sectional view through the fan.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, in the illustration given, the device comprises 'an electric motor I 0, a fan casing II, which is attached to one end of the motor casing, and the rotary fan wheel l2 arranged within the casing H and driven directly from the power shaft of said motor It. This casing H for the fan wheel has the air intake ports l3, and through the medium of a union M has connection with a hose ii for coupling with an air and spray gun.

The gun comprises a barrel l6 having a handle ll, the latter being in the form of a pistol grip handle.

The handle II has formed therein a passage l8 for communication with the bore of the barrel l6 and within this passage is a tubular electric heating unit l9, it being arranged in an electric circuit 20 having the therein. The wires of the circuit 20 are trained motor I through the handle I1 and such circuit is opened and closed by a hand operable switch 2| fitted within the handle I! and having a trigger 22, manually operated. The. switch 2| is normally held in open position by an expansion spring 23 as mounted within the handle IT. The switch 2| has combined therewith a cut-off valve 24 which opens and closes the communication between the passage and the barrel Hi, the valve 24 being normally in closing position switch 2| has opened the circuit 20.

when the The passage l8, at the free end of the handle H, has

fitted therewith a nipple 25 to which is the hose I5.

connected communicative with each other.

The nozzle 26 is detachably coupled, at 32, to the barrel '6, and in lieu of, the nozzle 26 there can be attached the blower nozzle 33, it being detachably engageable, at 32, with the barrel [6.

In the operation of the device, when the nozzle 26 is attached, on depressing the trigger 22 the switch 2| will close the circuit 20 and the valve 24 will open communication between the passage [8 and the barrel l6.

Upon closing of the circuit,

the motor ID will drive the fan I2 and thus forcing air through the hose [5, passage 18 and barrel l6 into the nozzle 26, a portion of said air underpressure being admitted to the receptacle or bottle 28 for the lifting of the liquid therein and the discharge of said liquid under pressure from the nozzle 26.

If it is desired to use the device as a hair drier the nozle 26 is detached and in lieu thereof is substituted the nozzle 33.

It will be apparent that the air under pressure passing through the passage l8 in the handle I! will become heated by the heating element l9 which is active on the closing of the circuit 20.

When pressure has been relieved from the trigger 22, the valve 24 shuts off communication between the barrel l6 and passage I8 in the handle I! and simultaneously the switch 2| opens the circuit 20, so that the motor becomes passive.

What is claimed is:

1. A device of the character described comprising a gun having a barrel and handle, the latter being of a pistol grip form and provided with a passage communicating with the barrel, a discharge nozzle removably fitted with said barrel, an electric circuit including a motor, a trigger switch fitted in said handle and included in said circuit for the opening and closing thereof, a fan operated by the motor and having communication with the passage in the handle for supplying air under pressure thereto, a liquid container connected with the barrel and in communication therewith, a valve in the handle for opening and closing communication between the passage in the handle and said barrel and carrying the switch, and an electric heating unit within the passage in the handle and included in said circuit.

2. A device of the character described comprising a gun having a barrel and handle, the latter being of a pistol grip form and provided with a passage communicating with the barrel, a discharge nozzle removably fitted with said barrel, an electric circuit including a motor, a

circuit, and a finger engaging piece on the valve 7 and arranged forwardly of the handle.

3. A device of the character described comprising a gun having a barrel and handle, the latter being of a pistol grip form and provided with a passage communicating with the barrel, a discharge nozzleremovably fitted with said barrel, an electric circuit including a motor, a trigger switch fitted in said handle and included in said circuit for the opening and closing thereof, a fan operated by the motor and having communication with the passage in the handle for supplying air under pressure thereto, a liquid container connected with the barrel and in communication therewith, a valve in the handle for opening and closing communication between the passage in the handle and said barrel and carrying the switch, an electric heating unit within the passage in the handle and included in said circuit,

.a finger engaging piece on the valve and arranged forwardly of the handle, and means for regulating the supply of air under pressure from the fan to the liquid container.
