To all whom it may concern:
Be it known that I, CHARLES FRANKLIN.
MARSH, a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have invented new and useful Improvements in Electrotherapeutic Apparatus, of which the following is a specification.
My invention relates to the art of electrotherapy; and its object is to provide an apparatus of a simple and effective nature for producing a current of such high frequency and potentiality and such low amperage as to render it extremely valuable for therapeutic purposes, the current being rich in penetrative force.
Another object is to provide the apparatus with electrodes of novel construction whereby an increased quantity of ultra-violet rays is produced, together with a ray more potent than the ultra-violet and less injurious to tissues than the X ray, this new ray being between the ultra-violet and the X rays.
A further object is to provide handles of novel construction connected to the electrodes.
With the above and other objects in View the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a diagrammatical view of the apparatus constituting myinvention. Fig. 2 is a plan view of the resonator, a portion thereof being broken away. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4C is a side elevation of one of the electrodes of the apparatus. Fig. 4* is a longitudinal section through the electrode. Fig. 5 is a transverse section through the electrode and showing the handle fastening means in section, and Figs. 6, 7, and 8 are elevations of modified forms of electrodes.
Referring to the figures by numerals of reference, 1 is a preferably octagonal frame forming the body of the resonator, and this frame has a covering 2, of felt, asbestos, or other soft material. A wire 3 is coiled about the frame from end to end thereof, and the terminals of the wire are embedded in a casing 4, extending longitudinally of the frame 1. Two conductors 5 are connected to the coiled wire 3 at points equidistant from each other and from the ends of the coil. These conductors are electrically connected to the source 6 of electricity and are likewise embedded for portions of their-lengths in a casing 7, extending longitudinallyof the frame 1.
The ends of the wire coil are each connected to an electrode 8 of novel construction. This electrode is formed of a tube of glass or other vitreous material, and one half thereof is filled with powdered carbon 9, while the remaining portion has an interior vacuum. A conductor 10 extends through one side of the tube and contacts with the carbon, and this conductor also projects through a felt or other soft covering 11, arranged about the central portion of the electrode. A metal yoke 12 partly. inclosesthe covered portion of the electrode, and this yoke has a screw-threaded stem 13, in which is located an adjustable contact-screw 14, adapted to bear against the conductor 10. A curved strap 15 is hinged to one .end of the yoke 12, and the other end thereof abuts against the opposite end of the yoke and has a springcatch 16 extending therefrom. This catch is adapted to project into and engage the wall of a recess 17, formed in the adjoining end of yoke 12, and a button 18 is located on the catch, whereby it can be easily depressed to unlock the straps and release the electrode. Stem 13 is detachably fitted in one end of a sleeve 19, of conducting material, and this sleeve is secured on an insulating-plug 20 by means of a screw 21, pin, or other suitable de vice. Plug 20 is arranged atone end of a handle 22, and, if desired, the plug and handle can be formed integral. One of the terminals 3 of wire 3 is secured to the screw 21 of each electrode.
The electrodes are used in the ordinary manner, and different forms may be employed for the treatment of different portions of the body. 1 have shown some modified forms in Figs. 6, 7, and 8, but all forms inclose vacuums and contain powdered carbon. As hereinbefore stated, by the use of this particular form of electrode a ray is produced which is of the utmost value in therapeutic treatment,
rich penetrative force, and exceedingly richin ultra-violet rays. The source of electricity referred. to, is a static machineor its equivalent for producing a non-continuous or alternating current. As thecurrent passes from the accumulators or condensers (Leyden jars) 6 through the connections and: tothe coilat points removed from: the'endsof the resonator'the tendency is-to pass :in either directiononthe coil, thereby producing waves and: eounterwaves, whichresultsininstability inpolarity, rapid interruptions in attractionsand repulsions in anodal. and cathodal=rays, and immensefrequency.
In the foregoing description I have shown the preferred formof: myinvention; but I do not limit myself thereto,- as I? am aware that modifications may be made, therein. without departing from the spirit or 'sacrilicinganyof thev advantages. thereof, and I therefore reserve the right to make such changesas fairly fall withinthe scope of my invention.
Having thus fully described my invention, what 1.- claim-as new is- 1.. In. an electrotherapeutic' apparatus, a static machine, a resonator,- conductors be-- tween the accumulators of said: machine and opposite sides of the center of the resonatorcoil and electrodes.connectedlto the-terminals of? the coil.

3. In an electrotherapeutic apparatus, a source :of electric current; a .coil'; conductors from said'source toopposite sides of the center. of. the coil, and treatment-electrodes connected: to the terminals of the coil.,
4. Aresonator-havingasourceofelectrieity connected to the coil thereofat points equidistant from the ends of the coiland from each other, and electrodes electrically connected to the terminals of the coil.
5. A resonator having a source of electricity connectedto-the coil thereof at pointsequidistant from the endsof the coil and from each other, carbon-containing vacuum-electrodes,
and electrical connections between the carbon in the electrodes and the respective terminals of the coil.
6. A resonator having a source of electricity connected thereto, electrodes each comprising a vacuum-tube containing carbon, the area of carbonequaling the extent of the vacuum, and electrical connections between the carbon and the resonator.
7. An electrode comprising a vacuum-tube, resistance material within said tube, and a conductor extending intothe tube and contacting with such resistance material.
8. A source of electric current, a coil, conductors from said source to opposite sides of the center of the'coil, and vacuum-electrodes containing resistance material connected to the terminals of. the coil.
