-JOSEPH CAMERON, OF MINNEAPOLIS, l

I ELECTBOTHEBAPEUQIC AIPABATUS.

To all whom it may concern l Be it known that I, JOSEPH CAMERON, a citizen of. the United States, residing at Minneapolis, in the countyof Hennepin and State of Minnesota, have invented certain wouldl otherwise be raised by the treatment.

The apparatus is held suspended over 'that part of the patients body to be treated and includes a fan for producing a blast of cool air, a portion of which is constantly delivered onto` the patients wrists through wristlets applied thereto, and under the` action of a rotary pulsator or vibrator, the remaining air from the fanlis delivered 1n a rapid succession of air pulsations or vibra 80 tions into a heating chamber. In this heating chamber is a heatin i, element, preferably 'in the form of a coi the temperature of which is controlled by av rheostat, as shown, applied on the top of the casing.

Below the heating chamber is a light chamber that contains light bulbs and a reflector having a skeleton dome. These hot air pulsations or vibrations are delivered from the heating chamber into the li ht chamber through the skeleton dome, w ich is preferably made up of vertically spaced concentrically located reflecting lenses of upwardly decreasing diameter. the light chamber are preferably spaced around an axially located focusing lens that is axially aligned with afocusing tube through which latter the heat wave and light rays are delivered to the point or surface on the patients body to be treated. The delivery through the focusing lens and focusing tube of the light rays will be constant, but the heat waves will be delivered with a sort of pulsating or vibrating action Ydue to the action of the rotary pulsator or vibrator.

and I do hereby,

which The light bulbs in .55 In the accompanying drawings, which ilappuoanon mea nay 4, was.I sei-m nt. eases.

lustrate the invention, like characters in? i dicate like parts throughoutfthe 'several views..

- Referring tothe drawings:

Fig. 1 is an elevation -of the apparatus with some parts broken away andv sectioned;

Fig. 2 is' a viewv of the apparatus principally in central vertical section, on an en'- larged scale;

Fig. 3 is a transverse section taken on the lline 3-3 of Fig. 2; A

Fig. 4 is a fragmentary detail view in central vertical section taken on the line 3-3 of Fig. 1; and

,Fig. 5 is a wiring diagram.

As one means of supporting tus, I provide a tubular standard 6 mounted on a truck 7 and having a\ tubular horizontal arm 8. A carriage 9 is mounted to travel on track rails 10 formed on the sides of the arm 8 and a grooved wheel loosely the appara,

journaled on said carriage and located within the tubular arm 8. A cable 12, within the arm'8, runs over the 'grooved wheel 11, and a-grooved, wheel 13 journaled in the tubular standard 6. One end of this cable 12 extends downward into the tubularstandard 6 'and has secured thereto a plurality of counterweightsl, and its otherfend'extends downward through a longitudinal slot 16 in the under sideof the arm 8 and is provided with a plurality of branch cables 17 from which the apparatus is suspended.

The apparatus includes a vertically disposed cylindrical casing 18 the upper end of which is open and the lower end of which lis closed with the exception of a focusing tube 19. This casing 18 is held suspended from the arm 8 by the cable 12 which is attached thereto by the branch cables 417.

These branch cables 'fare secured to the cas-y ing 18 at circumferentially spaced points by eye-equipped lugs 20.

Within the casing 18 is an upper fan housing 21, an intermediate heating chamber 22, and a lower light chamber 23 from the bottom of which the focusing tube 19 leads. In the top of the fan housing 21 is a large axially located air intake eye 24 and in t e conduits 27 having nipples 28, for a purpose` which will presently appear.

. the armature shaft 31 and driven therefrom is a rotary pulsator or vibrator 33 located-in the fanhousing l21 through the bottom o ii which said armature shalt projects. This pulsator or vibrator 33 (hereinafter referred therebetween.

to as a pulsator) is in the form of a flat disc located just under the bottom oi the fan housing 21 vfor rotation in a plane parallel thereto and having two circumterentially spaced ports 34 arranged to be intermittently brought into registration with the ports 25 leading from the tan housing 21 under the rotation ci said pulsator by the motor 29.

Mounted within the heating chamber 22, nea-r the top thereof, is a heating element 35 in the form of a coil, and interposed between the pulsator 33 and the heating element 35 is a heat deiecting hood 36. A

cluster oi' electric li ht bulbs 374 is mounted.

in sockets'38 circum erentially spaced around the focusing tube 19 and secured in the bottom of thelight chamber 23. Axially located within the light chamber 23 above the ocusin tube 19, is a focusing lens 39 having on 1ts frame Ll0 a pair of collars a1 slidably mounted on a pair el upright diametrically opposite posts i2 and secure'dthereto in di erent vertical adjustments by set screws 43.

Located over the light bulbs 37 and focusing lens 39 is a conically formed reector 45 having a large axial opening over which is located a skeleton dome comprising a plurality o f concentric rings i3 and a top plate 47 vertically spaced to leave air passages 48 i6-a7 aord a partition which separate the heatin chamber 22 from the light chamber 23. or controlling the temperature of the heating element 35,- there is provided a rheostat 49 mounted in the top of the casing 18 but spaced from thesides thereof to leave an air intake passagewa 50..

rlhe temperature of t e heating chamber 22 is' registered by a thermometer 51 mounted in a casing 52 secured to the outside or the casing 18, and the upper end of which casing 52 is connected to the fan housin 21 by a conduitv 53, andthe lower. end of wich is connected to the heating chamber 22 by a conduit 54. Obviously air is free to circulate around the thermometer 51 throu h the casin 52 and conduits 53 and 54; acess may had to the interior of the casing '18, between the electric motor 29 and rheostat 49, throu ha hand hole normally closed by a cover p ate 55. To keep a patientls blood rl"his redector dei and dome heretic by the apparatus, cool air, from the fan 32,.

is applied to his wrists, as previously stated,

by means of wristlets 56 having nipples 57 connected by hose sections 58' to the nipples 28. Obviously, air entering the pockets 26 from the fan 32 will pass through the conduits 27, nipples 28, hose sections 58,. and nipples 57 to the patients wrists. The wristlets 56 are held on a patients wrist by means of spring-acting clamps 59.

Referring now to the wiring diagram shown in Fig. 5, the numeral 60 indicates.

lead wires connected by a socket 61 to a heyecguip ed lamp socket 62, attached to a duplex lamp cord 63 leading from any suitable source oi suppl The electric motor 29 `is connected to t e leadwlres 6() by a` pair of branch wires 64 Ain one of which is interposed a switch 65. rlhe heating element- 35 is connected to the lead wires 60 by a pair of branch wires 66 in .one of which is interposed the rheost-at 49 and in the other of which is interposed a switch 67. The light bulbs 37 are connected parallel to the lead wires 60 by al pair ot branch wires 68 in one of'which is interposed a switch 69.

During the treatment of a patient by the apparatus, he lies on a couch 70 over whichsaid apparatus is suspended. rlhe counterweights 15 hold the apparatus where positioned at dierent elevations, and permit the same to be raised or lowered,and the carriage 9 truck 20 permit theapparatus to' move horizontall into diil'erent positions over a patiente bo y.

Preferably, the concentric rings- 46 and the oever plate 47 have reecting surfaces withinthe light chamber 23, and the back of the reflector 'et within the heating chamber 22 is covered with a suitable insulating material 71. rlhe entire casing 18 is encased by a nishing shell 72 between which and said casing is an insulating material 73.'
