REINHOLD H. WAPPLER, 0F YONKERS, NEW YORK, ASSIGNOR TO VVAPPLER ELECTRIC COMPANY, INC., OF LONG ISLAND CITY, NEW YORK, A CORPORATION OF NEW YORK.
Application led January 14, 1924. Serial No. 686,233.
My invention relates to electrodes, of a kind suitable for use in supplying electric currents to the skin of a patient, for purposes of therapeutic treatment, electrical massaging and the like.
More particularly stated, my invention comprehends a metal foil electrode; that is, an electrode having the form of a sheet and provided with a facing of metal or other conducting material, the sheet with its facing being as a whole so flexible that it can be applied to the skin after the manner of a plaster, and can be fitted around or between various physiological members of different form, such for instance as the fingers, toes, wrists or ankles, and can be fitted effectively upon such parts as the nose, ears or throat.
Reference is made to the accompanying drawing forming a part of the specification, and in which like reference characters indicate like parts throughout the several figures.

Figure 11 is a side elevation of still another form of my invention.
A flexible member 11 of sheet material, such as a sticking plaster, is adhesive on one of its faces, and adhering to this face is a coating of copper foil 12. Mounted uponl this coating of foil is a binding post 13, to which is secured a wire 14. The binding In the forni appearing in Figures 5 and 6, a flexible sheet of material is shown at 19, and is adhesive on one of its faces. Engaging the adhesive face is a strip 2O of copper, and extending over this strip and over the adjacent port-ion of the adhesive face of the plaster is a coating 21 of tin foil. A binding post 22 is mounted upon the strip 20, and leading to the binding post is al Wire 23.
In the form shown in Figures 7 and 8 the member 25 is a flexible sheet of material, such as a plaster, adhesive on both of its faces. Adhering to these faces are twocoatings 24 and 26, made of tin foil. The coating 26 carries a binding post 27, and leading to the latter is a wire 23. The two coatings 2li and 26 are both in communication with the binding post, and may be used either together or singly for the purpose of distributing the `electric currents.
In the form shown in Figures 9 and 10 a flexible sheet of material 30 is adhesive on both of its faces, and clinging to one of these faces is a strip 31 of tin foil, and to the other a sheet 29 of soft rubber, serving as a backing. The strip 31 is provided With an end portion 33, which protrudes through a slot 32, and secured upon this end portion is a clip 34, serving as a binding post. Thus while the strip 31 is adapted to make a good contact with the patients skin, and while in practice the electrode is so worn by the patient that the sheet 29 of rubber is outside, the tin foil strip 33 and clip 34 are also outside, and always accessible for making an electrical connection.
The flexible sheet with its adhesive face or faces is made of insulating material.
In the form shown in Figure 11 a sheet of soft rubber appears at 35, and a sheet of flexible material, adhesive on both of its faces, is shown at 36. A strip of tin foil appears at 37, and is in communication with the binding post 38. A clamp 39 is clipped upon the ends of the electrode, and serves to hold the electrode in position upon the part to which it is applied, as for instance an.
arm or a leg. The clamp, 39, is not energized electrically, and therefore ma f be placed directly in contact with the patlents skin without. the possibility of causing the current to make a burn. The clamp 39 may be used with the. form shown in Figure 10.
The operation of my device is as follows:
The electrode is by aid of the binding post or the-clip and wire which it carries, connected with a suitable source otelectricity, such for instance, as a faradic battery or other device furnishingr currents or current pulsations suitable for use in therapeutic operations, electrical massaging or the like. A pair of the electrodes here described may be used together, or a single electrode may be used in connection with an electrode of ordinary construction. The electric currents or pulsations are turned on, regulated and stopped, in the manner well understood in this art.
A very great advantage oll'ered by my improved electrode is that, in consequence of its flexibility, it may be easily bent around a member such as the thumb, one or more fingers, one or more toes or the like, one or both wrists or ankles. or may be fitted partially around or against any physiological member of peculiar contour, or may be curved or otherwise readily formed so as to fit partially into parts such as the out-er ear, or made to follow the contour of the skin covering the armpits, or the like.
I find that by means of this improved electrode the electric currents can be distributed far more uniformly than is the case with most other electrodes, and that the treatment can thus be rendered more effective.
Another advantage possessed by my improved electrode is that it can be made up ot cheap material and more or less perishable. and on that account may be cut by scissors into various sizes and shape, the finished article having a high degree of flexibility and being adapted to make good contact with the skin of the patient upon any part ot' the body, regardless of the shape of the partel to which the current is to be applied. ll`he. electrode thus made up can be used once, and then if need be thrown away.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:
1. An electrode, comprising a flexible sheet of non-conducting material provided with a slot, and a coating of metal foil .sccured flatwise against said flexible sheet of material. said coating of metal foil being provided with a portion extending through -said slot in order to facilitate makingr an electrical connection with said coating of metal foil, said flexible sheet of non-conducting material and said coating of metal foil being as a whole flexible, substantially as described.
2. An electrode comprising a flexible sheet of non-conducting material, a flexible sheet of metal foil secured flatwise against said first mentioned sheet but shorter than the latter as to leave an end portion of said first mentioned sheet extending beyond the end of said metal foil, and a clamp connected with the portion thus extended.
