Description

June 3, 1930. w. G. sHELToN HAIR DRIER Filed Deo. 17, 1928 Patented `lune 3, 1930 WILLIAM G. SHELTON, OF ST. -LOUIS, MISSOURI HAIR DRIER Application led December 17, 1928. Serial No. 326,584.

My invention relates to hair driers, such as are in use in beauty parlors, and conslsts in novel housing, operating structure and switch arrangement.

One of the objects of 1n y invention is to p rovide a housing or casing for the operatlng parts which will be simple and of neat appear-ance, strong and easily cleaned.

Another object of my invention 1s to arrange a motor, a fan, heating elements and a therapeutic lamp in such relation that the air currents created by the fan will pass over the motor, tending to cool the same, will receive the maximum amount of heat from the heating element and from the lamp, and will be directed from the drier with a minimum amount of interference in their passage therethrough.

Another object of my invention 1s to arrange the circuits and control switches therefor so that the device may be most easily and effectively operated.

In the accompanying drawings which illustrate a selected embodiment of my invention- Figure 1 is a longitudinal vertical section through my device.

Figure 2 is an elevation of the left hand end of the device as illustrated inr Figure l. Figures 3 and 4 are vertical sections taken on the lines 3 3 and 4 4 of Figure 1.

Figure 5 is a wiring and switch diagram.-

The housing or casing 1 is of cylindrical cross section and 'cncloses a ring-like frame 2 having a plurality of spokes 3 extending inwardly from its perimeter and mounting the motor frame 4 at their inner ends. The left hand endlof the motor shaft 5 mounts the fan 6 and the right hand end of the motor 10 frame mounts a pair of perforated plates 7 which grip the inner portion of an insulator member 8 which carries the heating elements 9 and 10 on a series of radial arms 81.

A perforated reflector 1l is also attached to the motor frame, this plate and plates 7 and 8 being secured to the frame by a screw 12. Atherapeutic lamp 13 is mounted on a socket 14 attached to the casing 1 to the right of insulator 8. Y

The left hand end of the casing, although y which tends to reduced in diameter, is provided with a substantial opening which may be closed by a suitable plate 15. This plate mounts the

switches

15, 16, 17 and 1,8 and the rheostat 19. The switch and the rheostat knob project through plate 15, as best shown in Figure l. The wiring of the device is all contained Within the casing 1, except the leadf'in cable 20 and the cable' 2l leading from the front of the device to the lamp socket 14.

The device, as a whole, is preferably mounted upon a yoke 22 by means of screws 23 extending through the ends of the yoke arms and the casing into frame 2.

By reference to the wiring diagram shown in Figure 5, it will be seen that the switch 18 for the motor must be closed before either of the heating elements can function as the heating elements each have oney terminal connected to the wire on the inner side of switch 18. This insures the operation of the fan whenever one of the heating elements is turned on and avoids undesirable heating of the device, due to careless inattention to the

heat switches

15 and 16. 75

It is obvious, however, that` the motor may be turned on without any of the heating elements being turned on. The same is true of the lamp 13 as its switch 17 is independent of the motor circuit.

The casing 1 is freely perforated at its left hand portion, as indicated at 24, and these perforations, together with the open construction of the motor supporting elements and the supports for the heating-elements'and the reflector for the lamp 13, make for free passage of the air through the device coolthe rheostat, cool the motor, and heat the air to the maximum degree for a given amount of current.

The mounting of the switches and rheo`V stat on the removable plate at the left hand" end of the casing enables the casing to be produced without any unsightly crevices and fastening devices or additional boxes for 95 housing the elements for controlling the electrical apparatus and also provides for ready access to the switches and wiring in case the .f same need attention.

Obviously in a device of this kind, many ments in the of the details may be varied without departing from the spirit of the invention and I contemplate such modifications in the structure as come within the scope of my claims.

I claim:

1. In a device of the class described, a frame member, a motor mounted on said member, a fan on one side of said frame and driven by said motor, a pair of clamping elements secured to said motor on the other side of said frame, an insulator gripped between said elements, a reflector in front of said elements, and a rlamp in front of said reflector, said frame, elements, insulator and reflector being constructed to allow an air stream to pass through the same and ast said lamp.

2. In a device of the c ass described, a motor, fan and heating elements, a casing enclosing the same and having an enlarged main portion, a tapering discharge portion leading from one side thereof, and an offset portion of restricted diameter extending from the opposite side thereof, switches 'for said motor and heating elements mounted in said offset portion, said offset portion being provided with openings to admit air around said switches.

3. In a device of the class described, a motor, fan and heating elements, a casin enclosing the same and having an enlarge main portion, a tapering discharge portion leading from one-side thereof, an offset portion of restricted diameter extending from the opposite side thereof, and having an open end, a removable plate closing said open end, and switches for said motor and heating elements mounted on the inner side of said plate with control lugs projecting therethrough.

4. In a device of the class described, a motor having a frame, a foraminous member extending across one end of said frame, a second foraminous member overlying said first mentioned member and projecting therewith to formI an insulator holding clamp, a foraminous reflector overlying said second mentioned member, a screw extending through said refiector and members into said frame' for securing said members and reflectorin place on said frame, and a lamp in front of said refiector. l

5. In a device of the class described, a cylindrical housing, a fan and a motor nea-r one end thereof, an insulator carried Vby said motor, radially spaced circular heating eleath of the air stream from said fan on said insulator, a lamp in front of said heating elements a stationary reflector for said lamp within the periphery of the innermost heating element and extendingbetween said lamp onnone side and said insulator and said fan on ther'othe'r side, said reflector being adapted to permit the passage therethroligh of air :from said fan.

6. In a evicepf the class described, a casing, a frame member, a motor carried thereby, a fan driven by said motor, a stationary refiector mounted on said motor, an insulator carried on said motor and radially spaced circular heating elements on said insulator outside of the periphery of said reflector, said insulator being between said fan and said reflector, a lamp mounted on said casing in front of said reflector, said frame, insulator and refiector being ioraminous to permit the passage. of air therethrough from said fan and over said lamp.

In testimony whereoi:` I hereunto affix my signature this 14th day of December, 1928.
