ELECTRO-MEDICAL BELT.

SPECIFICATION forming part of Letters Patent No. 424,827, dated April 1, 1890.

Application filed December 2, 1889. Serial No. 332,314. (No model.) I

To all whom it may concern:

Be itknown that 1, WILLIAM J. SHELTON, a citizen of the United States, residing at Golumbia, Brazoria county, Texas, have invented certain new and useful Improvements in Electro-Medical Appliances, of which the following is a specification.

. My present invention relates to improvements in devices for applying the electric current to different parts of the human body, and has for its object to provide a device which will be convenient in form, economical in structure, and durable in use, the device being provided with means for applying the current to any part of the body without the necessity of carrying a bulky appliance at the part.

The invention consists in a belt or support constructed of multiple-ply electro-conductive belting, which I make by inserting a conductor or conductors between the folds of a multiple ply band with suitable contactpoints at the surface, a sling supported by and movable 011 the belt for carrying the electric generator, also constructed of the electro-conductive belting, and having detachable connectors between its contact-points and those of the belt-contact plates, consisting of disks or plates provided with tongues or loops which engage over the edge of the belt and pass into loops or sockets formed on the surface-contacts, and a generator or electric supply consisting of a primary battery and a converter or induction-coil, each inclosed in a hermetic cylindrical housin g, preferably made of hard rubber, and having the axial binding-screws for making the primarycurrent connections, said converter being also provided with peripheral bindingserews, and a projecting knob by which the sheath surrounding the core of the coil is moved to regulate the tension, a scale-indicator and friction device being also provided.

The invention will be more fully understood by reference to the accompanying drawings, in which- Figure I is a perspective View of the simple form of belt. Fig. II is a similar view showing the manner of applying the current through the eleetro-conductive belting to the different parts of the body. Fig. III is a transverse section through they belt, the contactpoint, and the contact-plate. Fig. IV is an axial section through the induction-coil in the plane of the projection for controlling the position of the sheath.

1 represents the belt, which is composed of the two pieces or plies 2, secured together by stitches or other suitable means along the edges and divided by a central row of stitches 3, for the purpose of separating the two conductors, which are passed along inside the strap, and this constitutes myimproved electro-eonductive belting, which may, if preferred, be made by the yard orin other quantities of any width and pieces severed for use as may be required.

5 represents the contacts or contact points, which consist, preferably, of simple metallic loops or sockets 6 with a stem 7, which passes through the outer thickness of the belt and makes connection with one of the wires therein. These loops are adapted to receive either the tongues S 011 the contact-plate 9 or the tongues 10 on the connectors 11, which connectors 11 may be used for connecting the sling with the belt or the primary battery with the induction-coil, or the primary battery with the contact-loops on the sling surrounding it, as well as for connecting the converter with its surrounding loop in the sling. The sling 12 is also constructed of the electroconductive belting, and may be similar as regards the interior conductors and the surface contact-loops to the belt. The connectors 11 may consist of flexible conductors having on one or both ends a hook or tongue 10 for insertion into the loops or sockets of the surface contact-points in any part of the sling or belt. If desired, this form of connector may also be used between the battery and primary coil of the converter, though this is not material, for it is obvious any connection suitable for the purpose may be made for completing the circuit between the several points.

A battery used in my present invention may be of any convenient kindsuch, for example, as the one described in my patent, No. 405,436.

14 represents the primary battery, 15 the connecting-posts at the ends thereof, and 17 the converter. This converter I make of an improved form and inclose it in a hermetic housing for the purpose of excluding therefrom the moisture from the body, which would injure the working parts. This converter consists of the primary and secondary coils, the movable sheath 1S, surrounding the core, the axial binding-screws 1 9,which connect with the prim ary coil, the proj eetion 20,which is connected with the sheath of the core for moving it for the purpose of regulating the current, said projection having 011 the outside a spring-frietion device 21, an indicator 22, which designates upon a scale 23 the position of the sheath with relation toithe induction-coil. The proj ection works through a slot in the housing. One end of the secondary wire of the induction-coil is connected to a screw 2+t,while the other is connected to a contact plate or ring 25, which is adapted to make connection with a screw 26 in the movable end of the housing, which is adapted to be screwed off to give access to the working parts of the induction-coil. The connection between the binding-screw and the end of the cap and the make and break device of the induction-coil is insured by means of a projection 27, which may be an extension from the support which carries the contact-point in the make and break device, and which enters a spiral-spring socket in the end of the bindin g-scrcw in the cap.

For communicating the current to the different parts of the body, additional straps 30, precisely similar in construction, though preferably smaller in size than the belt, may be used, and the connection between these or the contact-points on these straps may be made by the same connectors as employed for connecting contact-points on the sling with those on the belt.

While I have thus specifically described the details of construction in my improved appliance,I do not limit myself to such particular construction, for the same is susceptible of various modifications which come within the principles of the invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. As an article of manufacture, electroconductive belting consisting of the multipleply band having the conductor or conductors inclosed within it, as set forth.

2. As an article of manufacture, electroconductive belting consisting of the multipleply band having the conductor or conductors inclosed within it, and suitable contacts on the surface connected with the conductors,.
