ELECTROTHERAPEUTICAL DEVICE.

Specification of Letters Patent.

Patented May 13, 1919.

Application filed July 25, 1914. Serial no. $153,009.

. a specification.

In another application executed on the same day herewith, Serial No. 853,008, filed July 25, 1914, I have shown and described a therapeutical appliance comprising var1- ous features, among which is that of a quartz lamp mounted in a cylindrical container which is provided with an opening through which ultra-violet rays may pass and which is also capable of rotation upon its central axis. In the said application the opening in the cylindrical container is closed off by an adjustable shutter forregulating the amount of surface to be covered by the rotation in any given instance. The said application also shows and describes the electrical circuits.

In the present application the improvement resides mainly in the substitution for the adjustable shutter of devices whereby the rays can be brought to the surface which is to be treated. The invention also relates to other matters which are closely associated with those named, as will appear from the present specification.

' In the drawings Figure 1 is a vertical section through the containing cylinder showing the parts within the same and various other details; Fig. 2 is an end view of the apparatus; and Figs. 3 and 4: are detail sectional views.

The main support for the apparatus is indicated at 1 as comprising a suitable head capable of being connected by a neck 2 with any suitable clamping device (not shown). Formed in one piece with or connected to the head 1 is a bracket 3, the arms of which embrace the ends of the cylinder 4. Inside the cylinder is a frame, 5, also provided with arms which terminate in journals or bearings, 6, 6, passing through the ends of the cylinder 4:. The journals 6, 6 constitute bearings for the cylindrical heads and the said cylinder is free to rotate about the bearings which pass through the central portion,

7, .7, being provided. Outsuitable washers,

3, nuts 8, 8, are

side the arms of the bracket the space between the quartz disks.

screwed on and prevented by pins 9, 9, from being inadvertently detached.

The part, 10, represents a quartz lamp having one terminal thereof joined to a binding post, 11, and thence by wire, 12, with one side of the circuit and the other terminal joined to a binding post, 13, and thence by wire, 14, to the other side of the circuit. For starting the lamp I employ a bell-crank lever, 15, one arm of which passes under a pin, 16, on a frame, 17, supporting the lamp and the other arm of which extends downward into line with a push rod, 18, so that when the said push rod is manipulated, the right hand end of the lamp, 9, is lifted and mercury is caused to flow from one electrode to the other thereby closing an electric circuit through mercury and ultimately, when the'mercury is ruptured, causing the startin of the lamp through vapor, the productlon of luminous rays and also of ultra-violet radiation. Vent holes, 19, 19,.carry'ofi' the heated vapors from the interior of the cylinder and a shield, 20, is also provided. The parts 21, 21, are observations windows.

At the lower side of the cylinder, as represented in the figures, there is an opening surrounded by a flange, 22, to which a telescopic device, 23, is secured, the same being rovided at its lower end .with quartz disks, 24: and 25, leaving a space at the lower end of the telescope which can be surrounded and kept cool by means of water circulation, asthrough inlet and outlet pipes 26 and 27 communicating with a pipe, 28, surrounding By this means the space and the disks may be kept comparatively cool, as is desirable, particularly in connection with the disk 25 which is adapted to be brought into intimate contact with that portion of the body which is to be treated by the apparatus. The walls surrounding the space-referred to are cut away to allow the pipe 28 to lie ercise thereby a more powerful effect upon the air within the space and upon the disks.

A modification of the device described is shown in Fig. 3 where the telescopic device is replaced by a tube 29 of small diameter adapted to be inserted in a wound upon the sub ect treated. Or, the telescopic device itself may be made small enough to serve this purpose. The tube 29 may be surwithin it and exrounded by a sleeve, 30, around which a pipe, 31, is wound spirally to provide for Water circulation for cooling purposes.

The angular portion of the cylinder and its openings may be shifted by means of devices such as lips 32, 32, at the top of the cylinder 4, embracing a continuous rim, 33, around the cylinder and cooperating with gripping plates 34, 34, adapted to be pressed by means of a thumb-screw, 35, against the rim, 33, for holding the apparatus in place after adjustment; i In both the described forms of apparatus the part through which the ultra-violet radiation emerges may be pressed against or into the wound. This might be of advantage in many cases since the described action Would tend to keep the blood away from that portion of the body to be treated and thus prevent the absorption of ultra-violet radiation by the blood itself.

I claim as my invention:

The combination With a quartz lamp of suitably supported quartz plates constituting the transition elements of the radiation of the lamp, said plates being spaced apart, and means outside the path of radiation for cooling the intervening space and the plates.

Signed at New York in the county of New York and State of New York this 23 day of July A. D. 1914-.
