HAIR IDBIER.

Application iled January 17, 1927.Y Serial No. 161,480.

This invention relates to hair driers and may be characterized as an improvement upon the hair drier illustrated and described radial flange in my prior Patent No. 1,541,988, of June 16, 1925.

The object of the present invention is to improve the operation ofthe device and rovide a generally improved and simplified construction that may be economically produced.

The invention is illustrated in the accompanying drawings, in which Fi 1 is an end view of a device ing tie present invention;

Fig. 2 is a longitudinal section taken on the line 2 2 of Fig. 1;

embody- Fig. 3 is a vertical transverse section taken d on the line 3-3 of Fig. 2; and

Fig. 4 is a vertical transverse section taken on the line 4-4 of Fig. 2.

The device shown comprises an open ended circular shell or drum 5 having a tapering discharge tube 6 attached at its larger end at 7 ,'to the open outlet end of the drum 5.

e discharge tube 6 receives and directs the air and radiant heat and light to the scalp and hair, or other surface or substance, as it is delivered from the device, and the attachment at 7 may be secured by forming a radial flange at the discharge tube end of the drum 5 and relexing the adjacent margin of the tube 6 into interengagement with the of the drum and pressing it securely thereupon. The outlet end 8 0f the tube 6 may be beaded at 9, for strengthening d and finishing the same.

The drum 5 and tube 6 are preferably of suitable sheet metal construction, although this may, of course be varied widely withiny the spirit and scope of the present inven/ tion.

At the inlet end 12 of the drum 5 is a spider 14 having an annular longitudinal r1m or flange 15 which fits telescopically into 5 and in which axial hub-like the inlet end 12 of the drum 5 and is secured therein, as by means of suitable screws 16. The spider 14 is secured therein, as by means of suitable screws 16. The spider 14 is preferably in the form` of a casting, although this, too, may be varied, and its radial arms or spokes 18 sulpport ani integral hub-like portion 19 axial y with respect to the drum portion 19 an electric motor 20 is mounted with revolvable motor shaft 21 disposed axially with respect to the drum 5.

The openings 24 between the arms 18 of 'the spider 14 constitutefjointly' the inlet through which the air is drawn into the device and this inlet is preferably covered by a suitable screen 25 secured peripherally between the generally radial flange 26 of the spider 14 and blocks 28.

The blocks 28 are of earthenware, porcelain, or other suitable non-inflammable material, and they are clamped to the interior of the flange'26 by screws 30, the Shanks of which extend through the blocks 28 and engage at their inner ends in' suitable nuts 32. The outer headed ends of the screws 30 are disposed for convenient access from the end of the A heating coil comprising a suitable metallic conducting wire is wound helically and supported in an open ii ure uponthe interior of the 'spider 14 and aient the openings 24 by the blocks 28. The coil 35 is'supported by the blocks 28 simpl by extendin it through openings 36 in saidy blocks 28, and while the-blocks 28 are secured to the ange 26,`they have a radial dimension which disposes the coil 35 in the path of the incoming air. f 4

' Mounted within the drum/5 is the reflector 40 in the focus of which the lam 42 is disposed to emit radiant heat and lig t through the discharge outlet 8. Thereector 40 has a generally longitudinal annular flange 43 which tits tightly. in the outer end 44 of the of the reflector 40 1s coincident with the axis of the drum 5 and tube 6 and its polished surface 46 is positioned toward the' lamp 42 and outwardly toward the outlet 8.

The reflector 40 has an axial opening 50 in which the fan or impeller 52 rotates to draw the air through the rear inlet o enings 24 and screen 25 and across the heating coil 35 and impels the air in the form of an axiall stream or blast over the lamp 42 and out through the tube 6 and outlet 8.

through the iange 26 `and` rum 5 and is secured therein by suitable` 'screws and nuts 45. The axis The impeller 52 is suitably fixed upon the Y motor shaft 21, as by means of a set screw 56 so that it will rotate with the motor shaft upon rotation of the same. which may be a high power electric light or incandescent lamp such as a nitrogen or high powered tun sten filament lamp, is mounted in vertical position in a standard or ordinary Edison socket 58, which 80ck- The lamp 42 l -be provided with a washer or collar 62 and the socket 58 extends radially inwardly from the wall of the drum 5. A diametrical set screw 63 secures the shank of the screw 60 against displacement from the internally ofthe scalp, and

as already o threaded end 'of the socket 58.- Sockets of this sort, with the internally threaded end `as shown, are of standard formation, and

by mounting the same within the drum by merely passing the screw 60 through the wall of thedrum and threading it into the internally threaded end of the socket, asimpliied and highly effective lamp mounting rovided. l

ne of ythe arms 18 of'the spider 14 has Aa hollow boss or hub-like portion to which a suitable three-way switch `65 is secured at 66. The hollow boss or hub-like formation is indicated at 68. The current supply conductor 70, which may be connected with any suitable source of current supply, enters the hollow boss 68 through an insulating bushing and has connection with the switch 65. The insulating bushing through which the conductor 70 enters is *indicated at 72. The conductors leading to and from the motor 20 are indicated at 73, the conductors leading to and from the heating coil 35 are indicated at 74, and the conductors leading to and from the lamp 42 are indicated at 75. The conductors enter the lamp socket .58 through'a suitable-lateral opening 76 in the base of the socket 58.

The switch 65 has a finger piece 78 which, pointed out, has three positions, one for c sin the motor and lamp circuits together, anot er for closing ,the circuit of the heating coil with the motor and lamp circuits and a third orfol position in which the motor, lamp and heating coil circuits are all opened. l i

In carrying out the present iniventon, as in the invention of my prior patent, the lamp 42 constitutes -the source of radiant heat and radiant light. vThe rays o f light and heat emitted by the lamp 42 are reflected by the reiiector 4 0 and pro]ected outwardly through the outlet end of thetube 6which, 1n use, is directed toward the hair and scalp or other surface. The discharge tube 6 directs the stfeam or blast of air and the rays of radiant heat and light, together to the iield of operation and focuses them there. By closing the motor and lamp circuits `together, the fan 52 is started and air is drawn in through the inlet o ening 24 and ro- ]'ected with the radiant Iheat and light rom the discharge end ofthe tube 6 u on the hair arid scalp.y Both the light and t e heat rays.

from the lamp 42 stimulate the circulation by so proportioning them relative the stream or blast of air, the resulting chill ismunteracted and the wet, clammy feelin is eliminated. Drying uickened and t e 'hair and scalp are' bene ted to a marked extent. By closing the circuit through thehheating coil 35 with the closed motor and lamp circuits, the ai'r may be heated, in addition, as desired in its passage through` the device.v

The axial 4opening 50 inthe reliector 40 with the disposition of the impeller or fan.

52 therein, results in the air being 'propelled through the device in the form of an axial stream or blast. By blowing the air over the lamp, the lamp is cooled and the possipensively formed and the motor -20 may be a relatively small high speed motor. The cost of the fan and motor may be thereby materially reduced andthe reflector, by its extension to the inner periphery of the drum 5, in addition 'to preventing the back pressures referred to, increases the reflecting power to the inner periphery of the drum. The weight and vibration is reduced and lthe life of the entire device is increased.

f For the purpose of preventing swirling, churning or circular motion of the air through the device, the tube 6 is provided with a pair of diametrically opposite ribs or fins 80. These ribs or fins are of angular formation with their lateral legs 82 secured to the interior of the tube 6. The'other legs of these ribs or insfproject radially into the tube 6 and are relatively liat or straight and extend vlongitudinally through the tube 6. Their'purpose is to project the air in a straight line from the device without swirling, churning or circular motion, and the width or radial dimension of each is therefore sufciently great to reach the axial blastH Aare pivoted thereto at 8 9. Intermediate its ends, the yoke 88 is shown as provided with a post 90 for mounting the' yoke and drier upon a suitable stand or other support.

For, oiling the forward bearing 90 for the therewith extends radially and is turned at 93 out through the screen 25 so that suitable oil/ may be introduced therein and will be Aconveyed to the bearing 90. v

The inner free longitudinal edges of the motor shaft 21, a tube 92 communicating ,1 25

ns 80 may be reenforced or strengthened and inished by doubling or folding back these marginal edges as indicated at 95.

The conditionvof the switch 65 maybe indicated at ,98.
