UNITED. STATES WILLIAM MEYER, OF CHICAGO, ILLINOIS. I

HAIR DRIER.

Application filed August 6, 1927. Serial No. 211,121.

This invention relates to hair driers and more particularly :to hair driers of the type illustrated and described in my prior Patent No. 1,541,988 of June 16, 1925 and in my 'copending application, Serial No. 161,480

filed January 17, 1927.

The objects of the present invention are to provide a generally improved and simpli-- fied construction that may be economically produced and to improve the operation of the device.

According to the particular embodiment which I have shown and described for the purpose of illustrating the invention and be varied within the scopev of thc appen ed claims, the incandescent lamp or source of radiant heat and light rays is brought toward the front of the casing and the means for preventing swirling or circular motion of the air and for directing the same in a straight line through the device is arranged behind the lamp and supports the heating element or coil.

The lamp is provided with a reflector, the periphery of which is spaced from the interior of the casing and forwardly of the reflector is an inverted conical ring for conccntrating'the air in its passage through the The outer diameter of the reflector is preferably substantially the same as the internal diameter of the opening through the inverted conical ring and the position of the reflector in back of this ring provides an annular space for the passage of the concentrated air through the device.

Rearwardly there is a partition provided with a conical opening adjacent the rearwardly directed smaller end of which the propeller for delivering the air through the device is arranged.

The partition defines the opening through which the propeller projects the air and this partition may support the blades for preventing swirling of the air, these blades in turn providing an admirable mounting for the electric or incandescent lamp.

A particular embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a longitudinal section through an embodiment of the invention on the line 11 of Fig. 2;

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

Fig. 3 is a transverse section taken on the scope into the adjacent end of the drum 9 line 33 of Fig. 1 and looking in the oppo site direction;

F ig. 4 is an end view taken from the forward end of the device; and

Fig. 5 is a circui t or wiring diagram.

The device shown comprises an open ended cylindrical shell 5, the forward end oi which forms an open outlet 6. The outlet end 6 may be headed at 8, for strengthening and finishing the same.

The rear end of the shell 5 is attached'to a cylindrical drum 9 which forms a continuation of the inner end of the shell 5 and the adjacent ends of the shell 5 and drum 9 are secured together through the margin of the partition 30 as will be hereinafter described, the adjacent end of the drum 9 being reflexed at 12, for this purpose.

The drum 9 and Shell 5 may be of suitable sheet metal construction, although this may, of course, be varied widely within the spirit and scope of the present invention.

At the rear end of the drum 9 is an end member flanged marginally at 16 to teleand detachably secured therein by suitable screws 18. The end member 15 may be rolled out adjacent the end of the drum -9 at 19 to finish the same and provide a shoulder for limiting the insertion of the endmember into the drum 9.

The end member has an axial opening 20 surrounded or defined 'by an integral hublike portion 21 and an electric motor 22 is mounted in this opening 20 with the revolvable motor shaft 23 disposed axially with respect to "the drum 9 and shell 5. For oiling the forward hearing 24 for the motor shaft 23, a tube 25 extends radially and is turned at 26 out through the end member 15 so'that suitable oil may be intrliducedd therein and will be conveyed thereby to the bearing for the motor shaft 23.

The end member 15 is provided between the hub-21 and its periphery with a plu rality of radially elongated openings 28 which constitute jointly the inlet through which the air is drawn into the device. This inlet may, of course, be screened if desired.

Arranged forwardly of the motor 22 and mounted in the rear end of the shell 5 is a partition 30 turned longitudinally at 32 to fit snugly in the shell 5 and flanged radially at 34 to engage in the reflexed end 12 of the drum 9, which reflexed end may be firmly pressed upon the flange 34 to bind the partition and drum securely together. The rear end of the shell 5 fits telescopically over the annular longitudinally disposed portion 32 of the partition 30 and is detachably' secured thereto as by means of suitable screws 35.

The partition 30 has a conical axially disposed opening 36, the smaller end of which opens rearwardly as shown. The fan or propeller 38 is disposed adjacent the reanoi' the opening 36, preferably with its forward edge in substantially the plane of the rear end of the opening 36. The propeller 38 is suitably fixed upon tie motor shaft 23, as-

by means of a set screw 39 so that it will rotate with the motor shaft, upon rotation of the same, drawing air through the rear inlet openings 28 and impelling the same forwardly through the shell 5 and out through the outlet 6.

For the purpose of preventing swirling or circular motion of the air through the device, the shell 5 is provided, forwardly of the partition 30 with a pair of right angle sheet .me'tal anti-swirling members 40 and 4:2 with their angular corners adjoining at 44 and their legs extending radially to substantially the inner periphery of the shell 5 and forming four blades 46 disposed norrnal or at right angles to each other. The blades 46 are recessed axially at l8 to receive a socket member 50, the base 52 of which is secured by screws 53 and suitable cooperating nuts to integral lugs or ears 54 struck transversely from the inner recessed edges of the blades d8.

The lamp 58 which may be a high power electric light or incandescent lamp such as a nitrogen or high powered tungsten filament lamp, is mounted in a horizontal position in the socket 50, which may be a standard or ordinary Edison socket. The lamp 58 is positioned toward the forward or front outlet end 6 in the focus of the for wardly directed and preferably polished surface of a reflector 60.

The reflector 60 is positioned forwardly of the blades 46 and has an integral hub 62 which fits telescopically over the socket 50 at 63. The hub (32 is split longitudinally, preferably at a. plurality of spaced places as indicated at 6 and its rear end is rolled inwardly at (35 to receive a wire 66 or other suitable means which is wrapped around the inwardly rolled end and clamps the reiiector 6O firmly upon the socket 50.

The peri hery of the reflector 60 is spaced rom the inner surface of the shell 5 and Iorwardly or outwardl of the reflector 60 is an inverted CODlCEU, ring 68 with its smalher end opening outwardly at 70. The outer open end of the ring (38 is spaced outwardly from the periphery of the reflector application, Serial No.

60 at a and the opening 70 which is axially disposed and in substantial alignment with the periphery of the reflector 60 is preferablyofan internal diameter substantially equal to the external diameter of the reflector 60, although this may be varied. The

rear end of the ring 68 fits snugly at 72 in the shell 5 and may be secured thereto by means of suitable rivets 73, although the mounting of this ring may, of course, be detachable if so desired.

A heating coil T5 comprising a suitable metalliewire is woundhelically and supported in a substantially closed figure upon the forwardly directed longitudinally extending portions 76 of the blades 46. For the purpose of supporting the heating coil on the blades 46 without electrical contact therebetween, the extending portion of each blade has an opening 78 and'a button 80 of suitable non-inflammable insulating material is clamped upon one side of each blade 46 adjacent the openings 78 by rings 82 having lugs 83 turned in through notches 8% in which blades 46 are turned back into cooperation with the opposite sides of the blades to clamp the insulating buttons 80 firmly thereto.

Three of the buttons 80 are aper'tured at 85 to permit the coil to extend therethrough. One end of the coil 75 is secured to and electrically connected with a terminal screw 86 on one side oi the fourth button as indicated at the top of Fig. 1 and the opposite end of the coil 75 is secured to and electricallyconnected with a terminal screw 87 on the opposite side of the same button.

The current supply conductor 90 enters the drum 9 through an insulating bushing 92 as shown in Fig. 3 and its conductors 93 are connected to three switches 91- 'roupcd together and secured byscrews So to the top of the wall of the drum 9. The group of switches is indicated generally at 96 and each is provided with an operating handle lever 97, which extends outwardly and is operable in a slot inthe wall oi the drum 5).

The switches shown are of the toggle lever type more fully disclosed in my to-pcnding 72,6li' filed December 2, 192".

The lamp 58, motor 22 and heating coil 75 are connected in parallel as shown in 5 with one of the switch levers 9T separately controlling each. The supply conductors 90 are adapted to be connected with any suitable source or current such as tor example a standard Edison outlet. One of the conductors 93 leads to one otlihe contacts of the lamp eontrollingswitch and to one oi the contacts of the motor controlling switch as shown in Fig. 5 and the other conductor 93 leads thrbugh tne heating coil 75 to one of the contacts of the heating coil controlling switch. The switch levers ,9? operate prel erably with a snap action and by operating one the lamp circuit is opened or closed independently of the motor and heating coil opened or closed independently of the'lamp and motor circuits.

In carrying out the present invention the lamp 58 constitutes the source of radiant heatand radiant light. The rays of light and the heat emitted by the lamp 58 are reflected by the reflector and projected outwardly through the outlet end 6 which, in use, is directed toward the hair and scalp or other surface. When the motor circuit is closed, the fan 38'is started and air is drawn in through theinlet opening 28 and projected with the radiant heat and light through the discharge end 6 of the device and upon the hair and scalp or other surface. The cooperation of the reflector 60 and conical ring 68 concentrates the air in its passage through the device. By closing the circuit through the heating coil 75 with the motor and lamp circuits closed, the air may be heated, in ad dition, as desired in its passage through the device. I

In operation the air is obviously blown across the heater 75 which is arranged between the fan 38 and the lamp 58 and the blades 46 which are disposed between the fan 38 and lamp 58 and support the heater coil 7 5 prevent circular or swirling motion of the air and direct the same in substantially a straight line through the device.

For supporting thedevice the drum 9 is provided with a pair of downwardly depending brackets 100 suitably secured to the bottom of the drum and pivoted at 102 between these bracket members 100 is the upper headed end of a post turn suitably secured in a post 104 which fits 103 which is in into and is extensibly mounted in an uprig t stand 105 having a suitable supporting base 106. For the purpose of securing the extendible post .104 in any desired extended or retracted position, the up right standard 105 is provided with a thumb screw 108.

The rear edges or ends of the blades 46 have integral laterally turned tongues or ears 110 which fit against and are riveted at 112 or otherwise suitably secured to the partition 30 and thereby firmly support the blades 46 upon the partition 30. Those conductors which extend from the switches 94 on one side of the partition 30 to the heating coil and lamp 58 on the opposite side of the partition 30 may be led through suitable openings 115 in the partition 30.

I do not, of course, intend to be limited to theprecise details shown or described.
