ALBERT H. DAVIDSON AND WILLIAM CLIFFORD MCKELLAR, 0F HUNTINGTON, WEST VIRGINIA.

ELECTROMEDICAL DEVICE.

To all whom it may concern:

Be it known that we, ALBERT H. DAVIDSON and VILLIAM C. l\'[oKuLLAn, citizens of the United States, and residents of Huntington, in the county of Cabell and State of West Virginia, have invented a certain new and useful Improvement in an Electromedical Device, of which the fol-lowing is a specification.

-The present invention relates to electrical apparatus particularly adapted for treating the human body, and more particularly to that type of device for creating static currents and applying the same in a peculiar manner to the body.

It is an object of the present invention to provide an electrical apparatus of this character which embodies the features of vibrating the portion of the body applied to the device and at the same time passing a pulsating current through the body to stimulate the same not only by the vibratory action, but also by the action of the high-tension currents passing through the body.

Another object of the present invention is to provide a device of this character which is particularly adapted for application to the hand or foot, and by means of which the hand or foot may be vibrated, and receive the currents therethrough, by the passing of the hand or foot over a corrugated or interrupted surface.

The invention still further aims at the provision of a novel electromedical device of this character which com rises but relatively few parts which may e incased in a cabinet or box, and which may be readily handled for the treatment of various bodily afflictions, such as rheumatism, nervousness, paralysis, poor blood circulation, to stimulate broken arches of the foot, and various other kindred elements.

The above, and various other objects and advantages of this invention will be in part described, and in part understood, from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings wherein:

Figure l is a longitudinal vertical section of a casing having the mechanism of this invention applied thereto.

Fig. 2 is a top plan View of the same with the cover removed, and parts being shown in section.

Specification of Letters Patent.

Patented June 19, 1917.

Fig. 3 is a fragmentary perspective View in sectlon through -one side of the intermediate portion of the casing, disclosing a bearmg for one of the rollers and the groove or chase for the reception of the wiring.

F1g. l 1s a perspective view of the case open, dlsclosing the rollers in position for contact with the hand or foot.

Fig. 5 is a top plan view of a slightly modified form of the roll support. I

Fig. 6 is a side elevation of the same, disclosing diagrammatically the circuits and the inductorium employed.

Referring to these drawings, wherein like parts are designated by similar characters of reference throughout the several views, 10 designates a case or cabinet of box form of any suitable size and construction, and which is preferably provided intermediate its ends with a transverse vertically extending partition 11 terminating short of the upper edge or top of the case 10. One end wall of the case 10 is provided at its upper end with a hinged section 12 adapted to be folded downwardly to expose the upper portion of the case. A cover 13 is hinged in anv suitable manner to one side of the case 1 0 and is adapted to be closed down thereon and over the hinged section 12 to completely inclose the case.

The case 10 is provided at one end and in the bottom thereof with a battery compartment formed between the partition 11 and a ledge or shelf 14 which is supported upon the partition 11 between the side walls and the adjacent end of the casing. Dry cells 15, or the like, are placed in this compartment while an inductorium 16 is mounted on the shelf 14. One terminal of the battery 15is connected by wire 17 to the vibrator and primary wlnding of the inductorium l6, and is then connected by wire 18 to switch 19, and back to the opposite terminal of the battery 15.

The wires 20 and 21 of the secondary winding of the inductorium 16 are extended in a groove 22 formed in the upper face of the shelf 14 to one end of the partition 11, and are then separated and conducted respectively through the grooves 23 and 2t formed upon the inner side of the adjacent wall of the case 10.

Mounted in the upper end of the case 10 adjacent the opposite end thereof are a pluralitj of rollers 25, 26, 27 and 28, four being shown in the present instance which are ar ranged in the same horizontal plane and which extend transversely across the top of the case 10. The wire 21 is connected tothe rollers 25 and 27, and the wire 20, isconnected tothe rollers 26 and28 so that the rollers are alternately connected to the opposite wires 20 and 21. .Each of these contact rollers is provided with longitudinally extending peripheral corrugations, and is provided at opposite ends with trunnions 29 which engage in bearings or bushings 30 fitting in the opposite sides of the case 10.

As shown in Fig. 4, when it is desired to use the device it is only necessary to\ raise the cover 13, and swing the end section 12 downwardly out of the way. The foot or hand may now be engaged across the top of the rollers 25, 26, 27 and 28,-and reciprocated longitudinally thereover. The rollers are free to turn and as the same are corrugated, the hand or foot applied thereto will be vibrated and the blood circulation thus stimulated throu h the member. In addition to this, the switch 19 may be closed to actuate the inductorium 16 and thus produce a pulsatin current through the wires 20 and 21 and 51rough the rolls in pairs, the current passing through the foot or hand applied to the rollers. It is thus evident that there is not only her which is moved longitudinally over the rollers, but also that the pulsating current is applied thereto. The case 10 may be placed upon the floor, the foot (placed upon the rollers and the cover an section 12 are 0 ened dmally over the rollers the foot is vibrated and stimulated by engagement with the corrugations of the rollers and also by virtue of the ulsating current which passes through the cot.

In the modified form disclosed in Figs. 5 and 6, the rollers are of the same'construction, but are mounted in a frame composed of a base plate 31provided at opposite sides with upstanding flanges or strips 32, the strips 32 being provi ed with bushings or sleeves 30 extending therethrough for the a mechanical vibration of the mem- By reciprocating the foot longitu- -on a table or the like when it is desired to place the hand upon the rollers.

When the case 10 is employed the wires may be covered by a lining 34 of fabric or the like, and the shelf 14 may be laminated for closing in and protecting in-wires.

It is of course understood that in lieu of the battery 16, any suitable source of current supply may be utllized for energizing the inductorium 16 for producing the pulsating current. v

Various changes and modifications may be made in the above-specifically described device without departing from the spirit of the invention, and eing restricted only by the scope of the following claims: I

We claim 1. In an electro-medical device, the combination of a series of four or more parallel rollers, meansfor supporting the rollers, and a high tension circuit havlng its opposite sides connectedalternately to the rollers.

2; In an electro-medical device, the combination of a base, a series of rollers mounted in the top of the base to provide an upper rolling supporting surface for the base, and a cover for the base including an end portion ada ted to be opened to expose the upper sur aces and the end of the series of rollers.

3. In an electro-medical device, the combination of a base, a series of rollers mounted in the top of the base to provide'an upper rolling supporting surface for the base, said rollers being provided with longitudinal corrugations extending transversely of the base, a cover for the base including an end portion adafpted to be opened to expose the upper sur aces and the end of the series of rollers, and a high tension circuit having its opposite sides connected alternately to the rollers.
