AVICTOR SENCE, OF NEW YORK, N. 1Y.

To all whom. it may concern: I

Bc it known that I, Vieron. SEXCE, a citizen of the United States of America, anda resident of the borough of Manhattan, city, county` and State of New York, have invented certain new and useful Improvements in Electric Belts, of which the following is a Blyv invention relates to electric belts in general and more specifically comprises means for rapidly o cning and closing the electric circuitin suc i belts in oider to produce a pulsatory current therein.

IIei-etofore electric belts have been employed, such lfor instance as that shown in Patent 638,14t3 to Albert T. Sanden, dated Nov. 2S, 1899, in which a flexible band or lcasing supports a series of small cells of electric battery which are connected together in sei-ics,`one terminal of one end of the last cell being connected -to a terminal or pad adapted to press upon the body of the wearer at one. point and the other element of the last cell at the other end ol the belt-being connected to another terminator pad adapted to press upon the body of the wearer at another point, whereby a complete -electric circuit is creat-ed through the belt and the body of the wearer, through which circuita continuous electric current generated by the cells cfa voltaic battery is sent.

I iind that it is desirable to rapidly open and close the circuit in such belts so as to change the continuous current heretofore used into a pulsatory current. I have invented a convenient form of apparatus for carrying outthis improvement, which together with one niodiiication is illustrated in the accompanying sheet. cf drawings, in which:

Figure 1 is a perspective view of an electric belt with my invention embodied therein, )arts being broken away. Fig. 2 is an enlarged detail of a vibrating switch driven by clock work, indicated in Fig. 1, and Fig. 3 is an enlarged detail of an electrically operated vibrator or suit-ch for automatically opening and closingtlie circuit with .great il iidity. ,l`hrougliout. the drawings like re erence figures indicate like parts.

l is the belt cover onband, and 2 and 3 are two terminals or .ads carried b f said belt l preferably at a point adapted to press upon the back oi' the wearer.

4 is another pad carried by the buckle strap 5 adapted to be attached to ,the belt so ELEcTRic BELT.

as to press upon the front of they Wearersv' body.

The belt band 1 carries a series of electric voltaic battery cells, one element of which cells is represented by 6, 6, while wii'es 7, 7, represent the terminals of the other elements of the battery cells. As shown, these cells are connected u i in seriesand the wire 8 eX- teiids from the last battery element 6 at one end of the belt to the pad 4, while metallic connection 9 extends from the wire connection 7 of the last cell at the other end of thev belt to the frame 10 of clock work.

'Ihe form of swinging switch and vibrating mechanism shown in -Figs. 1 and 2, comprises the metallic frame 10 of a clock work carrying the clock train 11 of any desired construetion having the usual escapement lever 12. 13 is a bifurcated contact mounted in insulation 14, carried on the main frame 10. 15 isa binding post on ythe exterior of the casing of the clock work connected to the contact 13.' 16 is a wire or other conducting connection from the binding post 15 to the pads 2 and 3. 17 is the key for winding up the spring ofthe clock train.

The method of operation of my inventionA rection accordinur to the arrangement of thebattery cells. Il now, vthe spring of the clock work is wound u i by means of the key 17, the mechanism wil be set in operation and the escape lever 12 will become a swinging switch vibrating between the two sides of the bifurcated contact 13. It is evident that this-will rapidlycpeii and close the circuit and change the continuous current into a rapidly pulsating current.

In the modified mechanism shown in Fig. 3, 1S is the magnet of an ordinary electric buzzer having the armature 1S), contact screw 20, 'buzzer circuit 21 in which is included a small cell of dry battery 22, and the controlling switch 23. llie main frame 27 on which the before deseribedparts are mounted contains two insulated cont-

acts

24, 24, serving as terminals for an opening or break in the wire 16.v 25 is an insulated bridge piece t i. i 1.

carried by an extension from

armature

19, and 26 represents insulation pro erly diseposed to preserve 'the integrity of t ie circuit through

wires

16 and 21.

In operation this device would be substi-' tuted for the clock work train previously described and would control the circuit through withdraw-'ing the bridge piece 25 wire 16. lllhen the switch 23 is open, as shown in Fig. 3, the bridge piece 25 would complete the circuit through wire 16. Then the switch Z3 is closed, the magnet 18 and battery 2) would come into action and ripidly vibrate the armature 19 in the manner of the ordinary buzzer, thereby alternately from contact with the terminals 24, 224, and returning it to such contact, thereby opening and closing the circuit to the electric belt apparatus at a high rate of speed and producing corresnonding pulsations of the currentI topass through the body of the wearer.

The advantages of myinventioncomprise the improved result on the patient produced by substituting the pulsating currentf continuous current, the compact constructi` n of the switch apparatus and its ready adaptability to the form of electric belt now on the market. Y:

The current necessary -for an electrical must be of fairly high voltage in order to prof closing said switch and means for operating current generated-by the belt cells.

2. In an electric belt thecombination with two terminal pads carried 'by said belt adapted to rest in contact with the body of the vwearer'at'opposite points of said body, of a circuit of conductive material connecting said pads, a' series of small voltaic cells ineluded in said circuit in series, a switch in said circuit, mechanism for opening and closing said switch and means for operating said mechanism Vseparate 4from the voltaic current generated by the belt cells, said means comprising a clock work mechanism.

3. In an electric belt, the combination with the wearer at o )posite points of said body, of a series of voltaic battery cells carried by said belt and having the positive pole of one cell connected to the negative pole of the next, the positive pole of the cell at one end ofthe belt being connected to one pad and the negative pole of the cell at the other end of the belt being connected to the other4 pad and means for automatically opening and LHclosing the circuit so formed, said meansl `comprising a swinging switch arm connected duce therapeutic results, but it must be oli to one terminal of the circuit, a bifurcatcd very low amperage or quantity in order no toproduce inflammation of the skin at the point of contact with the electrodes. The cells of voltaic battery here shovm have 4a voltage of about three quarters of a volt each, and the large number of them connected up in series gives the necessary voltage. The amperage is so small, however, 'that no form of magnetically operated circuit breaker can be actuated by it. Hence I prefer the clock work circuit breaker shown in F 2 of the drawings for this and other reasons. A magnetic-ally operated circuit breaker actuated by a separate cell of dry battery of sufficient amperage might be substituted for the clock work circuit breaker if desired, or a small cell of storage battery might be used. In these cases the current going through tire patients body would still be generated solely by the cells of voltaic battery in the belt while the low voltage, high amperage current of the other battery would be used solely to open and close the magnetic circuit breaker.

Having, therefore, described my invention, I claim: A

1. In an electric belt the combination with two terminal pa :ls carried by said belt adapted to rest in ccntact. with 1l-.e body of the wearer at opposite points ci said body, of a circuit of conductive material connecting said pads, a series of small voltaic cells included in said circuit in series, a. switch in t pntact piece between the ends of which said. xswitch arm moves connected to the other terminalxof the circuit, and a clock work mechanismfor vibrating said switch arm.

In'an electric belt, the combination with two terminal pads carried by said belt and adapted to rest in contact with the body of the wearer at o )posite points of said body, vof a series of voltaic battery cells carried by said belt and having the positive pole of one cell connected to the negative pole of the next, the positive pole of the cell at one end of the belt being connected to one pad and the negative pole of theccll at the other end of the belt being connected to the other pad and means for automatically o )ening and closing the circuit so formed, sait means including a vibrator included in the said circuit, and composed of a metallic clock work mechanism to the frame of which onc end of said circ-uit is connected, a bifurcated contact piece to 'which the other end of the circuit is connected and between the ends of which the escapement lever ot the clock work vibrates, and an insulated bearing forsaid contact piece mounted on the clock work frame.
