PORTABLE ELECTRIC-LIGHT CABINET.

. Light Cabinets, of which the following is a walls non-conductors of heat and for making specification.

My invention is in-the nature of a new portable electric light cabinet, designed for.

treatment of the body by the therapeutic influence of different colored lights in such diseases as rheumatism, neuralgia, migraine, inflammations, &c.

It is especially designed to provide a light, simple and portable apparatus which the patient can apply himself to the various parts of the body in home treatment, and which shall be so constructed as to be conveniently handled and applied and which will permit various colors of light to be separately or simultaneously used and which an even distribution of any one color within shall be free from all risk of fire.

It consists in the novel construction and arrangement of the portable cabinet, whichI will now proceed to describe with reference to the drawing, in which Figure 1 is a front elevation. Fig. 2 a rear perspective view with the back plate removed and showing the wiring. Fig. 3 is a side elevation and Fig. 4 is a section on line 44 of Fig. 2.

In the drawing, A represents the outer case which is an approximately square box-of a little less than one cubic foot in dimension, so as to be easily handled by the patient in his two hands and "for which purpose two handles a a are fixed, one to each side of the case, in convenient position to be grasped by the two hands of the patient in applying thev case to his own 'body. One side of the box is entirely open and its edges e are curved to fit the contour of the body, or part of the body,-to be treated and are padded or bound with rubber. The upper and lower walls of the box and the two side walls and back are all closed and lined interiorly with mirrors B preferably made of polished metal and havmg between them and the wooden walls of the box a lining b of asbestos to render the a fire proof construction.

The back of the boxcarries the electric light bulbs C which project into the box and, as shown, are about 50 candle power each and nine in number, but which maybe of a Specification of Letters Patent.

greater or less number. The back wall of the box is'made double, the inner back wall D receiving the sockets of the electric bulbs and the space between the inner back wall D and the outer back wall D forming a shallow chamber for the wiring.

The box is made somewhat narrower at the back than it is at the front or open side, forming shoulders s s on the sides in the plane offthe inner back wall D of the box. The outer, back wall D is made detachable and is secured by screws so as to be convenchanging the wiring.

Ofthe nine electric bulbs shown, those of themiddle vertical row are white glass, while those of the two vertical side rows are colored with each other. The red bulbs are indicated in Fig. 2 by the letter R the blue by the letter B and the white bulbs by the letter W This mixed relation of colors is to give the box as seen in Fig. 1. p

In the external recess-s on one side of the box are arranged three switches constructed as plugs P marked respectively red, white and blue, as seen in Fig. 3. When the red plug only is in, only the red bulbs are illuminated; when the blue plug only is in, only the blue bulbs are illuminated and when the white plug only is in, only the white bulbs are illuminated and when all of the plugs, or any two of them, are in, the corresponding bulbs are illuminated to give mixed colors. These colorsmay be changed,

or extended, or modified as may be desired. I For illuminating the lamps of the portable cabinet a duplex conductor cable E is employed, which at one end has a socket plug F may be conveniently screwed into any receiving socket connecting with the main wires of any electric light' system. The end of this cable is connected to the box, and the wiring of the lamps is as follows, reference being had to Fig. 2.

Each switch plug P has a plug socket consisting of two half round parts between which the plug P fits and which two parts are part p is an insulated piece of metal belonging exclusively to its plug P. The other part of each plu socket is formed of a half round notch in a past all the plugs and is common to them all.

The other wire y of the cable is connected to the opposite poles 'y of the lamps through the lugs P as follows: The Wire y'-'is connected to the long socket the lamps are connected as follows; the poles y of red lamps R are all connected by Wire '12 with each other and to the individualsocket plate 1) of the when the red plug P is in its socket, the' circuit will beclosed through the red lamps and the latter illuminated. The poles 'y of the White lamps W in like manner, are all connected together by wire it and also to the individual socket plate p of the White plug socket, so that when the White socket lug is in its socket, the current will be close through the White lamps and the white lamps illuminated.

1 individual socket plate p of the-blue- Thepoles y of the blue lamps B are allconnected together by wire 2 and also to" the socket, so that when this plug P is in, the drcuit will be ,closed through the blue lamps and the blue lamps illuminated and when all the plugs are in, all the lamps of the several colors will be illuminated, .In this way the therapeutic effect ofany color of light is i made available with areat variety o'f modifications and changes 0 intensity.
