SPECIFICATION forming part of Letters Patent No. 496,244, dated'April 25, 1893.

Application tiled September 28, 1892. Serial No.447,095. (No model.)

To all whom, t may concern:

Be it known that I, FREDERICK A.l BARRET, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Electro -Galvanic Adhesive Plasters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

xo My invention relates to improvements in lelectro-galvanic batteries in conjunction with adhesive plasters, for facilitating the cure of certain diseases and ailments, Well known to the medical profession and which for the main i5 part, necessitate a means for quickening the circulation of the blood. l

My improvement relates especially to electro-galvanic adhesive plaster, and consists in the peculiar construction and combination of 2o parts as will be more fully hereinafter described and set forth in the claims.

It is a generally accepted fact among knowing persons, that the application of an exciting current to diseased or weak portions of the human anatomy causes the tissues to become built up and strengthened. Necessarily the facilities for producing an exciting current, Without inconveniencing the party to whom it is applied, are limited and in devel- 3o oping this line of remedies, numerous designs of belts, foot-pads, and so forth, have been designed, and it is generally believed that the galvanic current produced by such batteries t as are used, is not strong enough to pass through a limb or even to exerciseadynamic action upon the nervous system, because the electro-motive force of such sources of generation, is so low that the intensity of the cnrrent will not in any Wise materially invigo- 4o rate the action of the human organism. Certain portions of the body are not adapted for the application of electricity from a belt or other source of energy, and therefore in developing my ideas I have made use of an adhesive plaster, which, of course, has an effect of its own and which will aid the effect of the current rather than lessen it. The plasters may be different in form and effect, and the desired result of their application will of 5o course be determined by the person govern-` ing the matter. In the use of my improved apparatus, even for a short time, the patient is not compelled to undergo the influences of 1 strong and rapidly diminishing currents, be-

cause .the power is constantly exerted and this feature renders the current agreeable,

and enables the most sensitive person to bear the action without any inconvenience. The ready removal of the batteries, from the plasters, renders the device especially valuable in diseases of long standing, as it is thereby possible for the patient to till the batteries with exciting fluid, whenever the same becomes interrupted in its action. By the use of my improvement, different portions of the body Y son with my complete 4invention applied to 75 several portions of the body. Fig. 2is a front orplan ViewT of my complete invention showing the plaster with all of the parts of myinvention connected therewith. Fig. 3 is a perspective view of a plaster with an electrode attached thereto, the same being used as an auxiliary appliance in conjunction with and forming a part of my improvements. Fig. 4 is a side view-of my complete invention as shown in Fig. 2. Fig. 5 is a perspective View 85 of one of the cells or batteries made use of in carrying out my invention. Fig. 6 is a perspective view of a core made of fibrous absorbent asbestus, the same being used in the manufacture of my device. Fig. 7 is a perspective vView of a rim or pad of-absorbent material, preferably felt, used in conjunction with the asbestus core shown in Fig. 6. Fig.

Fig. 9isa modi- 95 tcation view of the complete device shown in Fig-2, with portions of a protecting covering for the batteries, broken away. Fig. 10 is an end view of the complete device as shown in Fig. 9 without parts of the covering-removed. too

Fig. 11 is a perspective view of one of the batteries made use of in the modified construction, and showing the same completed with a split head insulated rivet. Fig. 12 is an elevation of one of the insulated rivets, showing the same with a thumb-nut upon its head, and the insulation in section. Fig. 13 is a view similar to Fig. 12 except that the rivet is a split one.

Referring to the drawings: 1 indicates the body of a person having applied to a certain part thereof, an adhesive plaster 2, with an auxiliary plaster 3 electrically connected with said plaster 2. The plaster 2 is preferably what is commonly termed a porous plaster and therefore has its medicated parts, provided with numerous small perforations 4, the function of whichis well known. Asis usual the plaster has three layers, and upon the outside or protecting` layer 5 of said plaster 2, and arranged approximatelyin the center of same, are cells or batteries 6, 7, and 8. In this connection I Will only state the batteries are electrically connected together in the proper manner, but will specify the connections further on in the description.

The batteries 6, 7 and 8 are located upon the exterior side of the plaster, When the same is applied, and in order that the current generated in said batteries 6, 7 and 8 will affect the desired parts, I have provided contact plates or electrodes such as 9, which are located upon the inner side of the plaster and therefore adjacent the skin when the plaster is in position. The electrodes 9 are preferably two in number, but can be increased to a greater number in case greater effective surface is desired, and different connections with the exciters made. The batteries 6, 7 and 8, consist of zinc or positive plates 10 and negative copper plates 11. Each of said plates 10 and 11 are provided with projecting ears or lugs 12, which are in the shape or form of interlocking hooks such as 13. In some instances, however, I may provide one of two opposing lugs 12 with a hook and the other lug with a slot, as shown at 14, to receive said hook.

In my practical experiments I have found that asbestus fibers or mineral wool constitute one of the best absorbents, and therefore in the line of my improvements, I have made use of a core 15 made of this same material andvformed in the shape of a circle, with a perforation 1G running transversely through its center to allow of the location of a rivet hereinafter described. Unless this same fibrous material is properly confined, it will disintegrate and to prevent this action, I make use of a collar or riln 17 provided with a large central opening 18 for the reception of the fiber core 15, said rim 17 being made of some absorbent material such as felt in order to assist the function of the fibrous core 15. The above described rim 17 with the core 15 in position in the perforation 18, is adapted to be placed between the positive and negative plates 10 and 11 and the function of said construction is the absorbing and retaining of any of the exciting fluids such as acidulated Water, vinegar, acetic acid, and so forth, and as neither one of the absorbent materials are electrical conductors, it is impossible for a short circuit to be established between the positive and negative plates 10 and l1.

The action of the exciting fluid absorbed and retained by the felt 17 and asbestus 15, upon the plates is well known and need not be detailed herein, except to say that such a means for producing the exciting current, is made available by the excitable elements of the Huids.

The three cells 6, 7 and 8 are connected in series that is, the copper-plate 19 of the cell 6 forms a terminal outlet, while the zinc plate 2O is connected with the copper plate 21 of the cell 7, whose zinc plate 22 is connected with the copper plate 23 of the cell 8, thus necessitating the zinc plate 24 of cell 8 constituting the positive terminal of the series.

The electrical connection between the batteries and the electrodes 9 is made by the use of what I term insulated rivets 25 which consist of an ordinary screw-threaded rivet bolt 2G with a thumb nut 27 adapted to be operated on the screw threads thereof.

In order to insulate the rivet I use a piece of insulation tubing which is cut into desired lengths, said length being controlled by the thickness of the cells and plaster, said tubings 28 being adapted to lit over the bolt 26 and have an insulation Washer 29, located between its outer end, and the inner surface of the thumb nut 27.

The insulation tubings 28 and washers 29 are made from any of the well known insulating materials, such as rubber, vulcanite, and so forth.

The perforation in the center of the electrodes 9, is not of a diameter sufficient to admit the insulating tubings 28 therein, and therefore the bolt head 30 has an electrical contact with said electrodes 9. Forinstance, if it were desired to establish an electrical connection between the copper plate 19 of the cell 6 and the electrode 9, the washer 29 is removed, as shown in Fig. 8, thus bringing the nut 27 into contact with the plate 19, and therefore allowing a circuit connecting the electrode 9 with the copper 19.

,l In order to establish an energizing current, `it is necessary to complete the same by elec- ,ltrically connecting the Zinc plate 24 of the cell 8 with its respective electrode, and this is jdone by the use of an electrical connector 31 fwhich connects the zinc plate 24 with the eleci trede 9, the rivet meanwhile beiug insulated from both plates of the battery.

It is necessary to make use of the electrode opposite to the cell 7, without neutralizing the effect of the other electrodes 9. This is ac-. complished by connecting said electrode with either of the terminal electrodes, while at the saine time it must remain insulated from the IOO IIO

other remaining electrode, in order to affect the completion of the circuit and the passage of the current.

The auxiliary plaster 3 is provided with an electrode 32 upon its inner adhesive surface,

said electrode 32 having a staple 33 upon its\ rear surface and extending through the plasters 3. An insulated wire 34 is secured in said staple and provided upon its opposite end with a snap hook 35.

In Fig. 4 I have shown the above described construction as attached to the copper plate 19 of the cell 6 and also showing in dotted lines a similar construction 36 which is adapted to be removably attached by means of its hook, to the zinc plate 24 of the cell 8.

When it is desired to use either one of the plasters 3, the cell to which the plaster is temporarily secured has its electrode electrically disconnected. This is done, in` the case of the cell 6, by making use of the insulating Washer 29, and in the case of cell 8, by removing the wire 31, and placing it in the position shown in Fig. 4. The wire of this plaster 3 (shown in dotted lines at 36, Fig. 4) is then in electrical communication with the cell 8. When it is desired to use both the plasters 3, the electrodes of both cells 6 and 8 are electrically disconnected in the manner described. This arrangement is made use of in case it is desired to affect different portions of the body. v

The cell shown in Fig. 5 which is similar t0 the cell 6 removed from `the plaster, has an outwardly projecting lug into Which the hook 35 of the Wire 34 is adapted to engage. In this same construction a modified form VVof rivet is made use of and the difference lies in the splitting of a portion of the length of the bolt 37 and in order to secure the plates together over the absorbent material, the

split ears 38 are bent down in a horizontal position over the washers 39, which is made of insulating material, and which is located at the end of an insulating tubing 40 (Fig. 13) as is the case in the other construction shown.

In Fig. 2 is shown in dotted lines a bag or protector 41 which is adapted to envelop thev battery cells and prevent the exciting liquid contained therein from soilingthe clothes and also prevents the evaporation ofthe fluid.r

In Fig. 9 I have shown a modied construction which consists of rectangular shaped cells v lprovide electrodes 46 for the two terminal batteries, the connection between such electrodes 46 and the batteries being made by the rivets hereinbefore shown and described.

If it is desired to. apply the current by means of the auxiliary plasters 3, one or both of said electrodes 46 are disconnected from the cells, by the insertion of the insulating washer underneath the heads of saidrivets.

In Fig. 11 the plates kof the cell are shown with projecting ears 47 by means of which the cells are connected together by wires or rivets, in preference to the use of the links 43, shown in Fig. 9. A protecting covering or sack 48 is provided for this constructionby making the same substantially in the form of an envelope, with the batteries located interior of the same and the flap 49 adapted to button overthe main portion of the envelope, as shown in Fig. 10, with openings 50 left in each end of said envelope 48 through which the ears 44 project. y

The shape, number and relative position and arrangement of the battery cells inv my improved device, is immaterial as long as the proper electrical connections are made, and any arrangementof the same differing from vthose herein shown do .not materially affect velopment of this idea I also preferably make IOO such iniiuences'are well known as to their action and effect. The connection of the cells in series increases the efciency and electro motive force of the currentjby augmenting and reaugmenting the strength of same with the connection of each additional cell. We will first suppose that the plaster is to be applied upon the body at what is considered a very weak portion of the human system, namely the smalll part of. the back. In. this IIO caseif the application is only to be made at f this place, the auxiliary. attachments 3 are left off and the `connection from the cellsY vmade direct withy they electrodes 9. This is done from the cell 6 by the removal ofl the washer as shown in Fig. 8, the contact 'or connection being made from the thumb-nut 27 to the bolt 26 and into the electrode 9.

The cell 7 is entirely insulated from the electrode 9, but said electrode 9 is electrically connected with .the electrode of the cell V6. The connection of the electrode 9 with the cell 8 is made by use of the loop 31 which connects the positive plate of saidpcell 8 with the electrode and asthejelectrode 9 ofthe cell l6 is connected with the minus plate of said cell k6, the completion of an electricalcircuit is made. -In case it is desired to transmit the electricity to different points of the body dis-,- tant from where the plaster is located,one'or both of the auxiliary plasters 3 can be made use of. We will first suppose that it is desired to aEeet a certain portion of the back. The washer 29 is placed between the thumbnut 27 and the plate 19 upon the bolt 26, thus insulating the electrode 9 from said cell 6. The hook 35 is then attached to the lug 14 and the current passes through the wire 34:

into the electrode 32 which is held in contact with the body by the plasters 3. If it is desired to transfer the remaining poles to eect another portion of the body, the wire 3l is disconnected from the zinc plate 24, and the auxiliary attachment 36 applied thereto, in which case, the electrodes 9 have no effect upon the surface in which they are in contact but the entire current passes into both of the auxiliary attachments. The necessity of disconnecting the electrodes 9 will be seen from the fact that the resistance in the Wires connectin g with the auxiliary electrodes 32 would be so much greater than that of the adjacent electrodes 9, that the current would preferably seek its outlet in said electrodes 9.

My improved electro-galvanic apparatus may be applied to any of the plasters which are now used in medicinal practice such as capcine plasters for irritation, or opium and belladonna plasters for soothing the diseased parts.

As before stated, the aiect of energizing currents upon diseased or weak portions of the body, is material and in attempting the perfection of appliances for treatment in such cases, I have tried to embody features which alone recommend themselves.

The advantages are readily seen: The extreme simpleness of construction and operation, the certainty of its eect, and its cheapness and durability of manufacture.

Having fully described my invention, what I claim isl. In an electro-galvanic adhesive plaster, the combination, with the plaster proper, of a battery consisting of a series of cells arranged at the back of the plaster, a series of electrodes arranged upon the face of the latter, and means for electrically connecting two or more of the electrodes with the battery and with each other, and for disconnecting the same; substantially as set forth.

4. In an electro-galvanic adhesive plaster, the combination,with the plaster proper, of a battery consisting of a series of reVersely-arranged cells, said cells each comprising a positive and a negative plate provided with reversely-projecting lugs 12, the opposinglugs 12 being electrically coupled together, and a porous filling separating said plates; substantially as set forth.
