PATENT ROBERT E. VILLIAMS, OF DALLAS, TEXAS, AND TURNER G. HAMMER, OF NEV ORLEANS, LOUISIANA.
SPECIFICATION forming part of Letters Patent No. 366,058, dated July 5, 1887.
Application filed January 24, 1837. Serial No. 225,331. (No model.)
T all whom, it may concern:
Be itknown that we, ROBERT E. WILLIAMs, of Dallas, in the county of Dallas and State of Texas, and TURNER G. HAMMER, of New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvementsin Electric Belts; and we do hereby declare that the following is a full, clear, and exact descriptionof the invention,
io which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective View of the inner side of our improved electric belt. Fig. 2 is a similar view of thc outer side of the belt,sho\v ing the belt opened to expose the elements or batteries. Figs. 3 and 4t are sectional views of one of the batteries, taken at right 'angles to each other. Fig. 5 is a perspective view ofthe parts of the battery separated. Fig. 6 is a perspective view ofthe auxiliary band or belt. Fig. 7 is a similar view of the end of the belt,
,25 showing the auxiliary belt attached to it; and
Fig. Sis a sectional view of one of the elecredes.
Similar numerals of reference indicate corre sponding parts in all the figures. 3c Our invention has relation to that class of electric belts in which a chain of batteries is inclosed in a belt having` -two poles or eleetrodes upon the inner side at the ends of the chain of batteries, and it consists in the improved construction and combination of parts of such a belt, as hereinafter more fully described and claimed.
In the accompanying drawings,the numeral 1 indicates a strip of a suitable fabric having 4o its inner side coated with a non-conducting material, and having its edges doubled over to form flaps 2, overlapping each other. Tapes or bands 3 are secured to the upper overlapping flap and passed over theinner side of the belt formed by the strip, the ends of the tapes serving to secure the overlapping iiaps, and the portion upon the inner side of the belt serving to form loops for the reception of a strip of material-such as annel or similar 5o material, if desired-for the purpose of avoiding the contact with the fabric of the belt with the body. A chain of batteries, 4, isinclosed in the pocket formed by the flaps of the belt, and each battery consists of a thick zinc plate,
v5, having a perforation, 6, at its middle and perforations7 nearthe ends, diverginggrooves 8 extending froln the central perforation upon the inner side of the plate, and of a piece of sponge or other absorbent material, 9., and a thinner copper plate, l0. Thecoppcrplateis formed with a long receptacle, 11, struck up at its middle, and a piece of sponge, 12, or other absorbent, may be placed Within this rcceptacle, and the piece of absorbent material is placed between the two plates, and the plates are secured together by suitable threads or'cords, 13, passing through the perforations in the plates and through the absorbent fabric. One edge of the copper plate is formed with a wide lip, 14, which is doubled inward; and the doubled end of a copper wire, 15, is secured in the hook formed by this lip and has its converging ends inserted through the central pcrt'orationin the zinc plate, whereupon the ends are spread to [it into the grooves in 75 the` inner face ot' the zi nc plate, the spread ends serving to retain the wires in position. The zinc plate of the batteryat one end is formed with a clamping plate', 16, of zinc, and a doubled piece, 17, of copper wire is attached to this plate and has its other end bent to form a hook, 18, and the copper plate at the battery at the other ,end has a long wire hook, 19, attached to its hooked lip. The inner side of the belt is formed with perforations 20, through which the eyed shanks 2l of two poles or electrodes, 22, project, and these electrodes are formed in the shape of buttons, having their convex sides forming a receptacle for a sponge, 23, or other absorbent, the outer con- 9o vex side of the electrodes having perforations 24. One of these electrodes is preferably circular, while the other electrode is oval, the oval form enabling it to more conveniently be placed against the back; but the form of the electrodes is, however, immaterial, being conformed to the place to which they are to be applied. A chain, 25, may be attached to the end of the long hook at the end of the chain, and the electrode at that end may be shifted IOC) into the farther perforations, when the chain may be attached to its eyed shank and con nected to the hook, thus enabling the same chain to be used with belts of different lengths by simply attaching the chain at the end hook. A pocket, 26, is formed at the copper end of the belt, and the overlapping tiap of this pocket is formed with perforations 27 through which the wire 28, having an insulating covering, may'pass into the pocket, the wire passing through an aperture, 29, in the seam which separates the pocket from the long pocket for the batteries, and being secured to the hook at that end of the batteries. A piece, 30, of tape or string is secured to the overlapping iiap of the small pocket, and' serves to secure the insulated wire when the latter has been drawn suftieiently far out of the pocket. The other end of the insulated wire is attached to a chain, 31, inclosed in a small band or belt, 32, of an insulating material, and a number of small hollow electrodes or buttons, 33, containing a suitable absorbent and having perforated faces, are secured to the chain with their eyed shanks 34, the said eyes passing through suitable apertures, 35, in the belty or band. The end of the insulated wire is provided with a snaphook, 36, or other suitable fastening, by means of which it may be detachably secured to the end of the Chain in the'belt.
It will be seen that the batteries in the chain may absorb and retain a considerable quantity of acid, having the layer of absorbent fabric between the plates, and having, furthermore, the piece of absorbent in the receptacle or cup formed in the copper plate, and the absorbent filling of the electrodes will admit of the current ot' electricity from the belt being administered gently to the body without any stinging sensation, which is liable to be felt if the current is admitted through dry electrodes.
'Ihe auxiliary belt or band may be used upon one of the limbs, and the insulated wire may be drawn out of the pocket to the desired length, whereupon it may be secured by the piece of tape upon the pocket, the wire being inclosed in the small pocketwhen not in use.
Having thus described our invention, we claim and desire to secure by Letters Patent of the United States belt and fitting upon the hooks of the chain of batteries, as and for the purpose shown and` set forth.
2. In an electric belt, the combination of a zine plate having perforations near its ends and a central perforation, and formed with divergng grooves from the central perforation upon the inner side, a copper plate having perforations near its ends and formed with a long bulge in its inner side, forming a receptacle, and having a wide hooked lip at one edge, a piece of absorbent fabric secured between the plates by threads or cords passing through the perforations in the same, a piece of absorbent in `the receptacle in the copper plate, and a piece of doubled wire having its doubled end held by the wide hook and having its ends secured in the perforation of the zinc plate of the adjoining battery, having the ends spread to lit in the grooves in the zinc plate, as and for the purpose shown and set forth.
3. In an electric belt, the combination of a` belt formed with overlapping lianges upon the outer side and having a'small pocket formed at one end, having perforations in the overlapping flange of the small pocket, a piece of tape Aupon the overlapping flange of the pocket, a
chain of batteries in the main pocket ofthe belt, and an insulated wire secured to one end of the chain of batteries and passing through the aperture in the row of stitches into the small pocket and through an aperture in the ange, having a snap-hook at its-end, as and for the purpose shown and set forth."
` In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
