    Impts. in Electro-magnetic Coils for Treating Live jlrmrud and other Objects. for instance, the oblong coil Q in Figure 1 may be increased or lessened in breadth; the former would lessen and the latter increase the magnetic effect on the object under treatment within the coil. I he pliant (oi can accommoc a itself to either regular or irregular forms, so that the whole length of the coil shall contact with the object under treatment, and the whole contacting pent ion of the object with the cable coil, shall receive equal magnetic force W hen a human being is the object under treatment, my experience lias shown that it the o produces in a dead wire parallel with it, and near eiiougn iv n, «.u - 10 current. For this reason also it is advantageous to have the pliable cable coil. When the induction coil transformer is used on the circuit, one form of which is shown in Figures 1 and 3, it is advantageous to connect the secondary terminals n and p with the primary terminals z and y, as shown m Figure * • n this way the current from the secondary coil will increase the effect of the ] 5 primary current in the pliable coil, but if the secondary terminals aie not con¬ nected in this manner or to a separate coil I, as shown in Figure 1, or its circuit closed by merely connecting its terminals, then said current is practically of no use for the purposes described. . Figure 4 illustrates my process with coils in multiple; a may be as 11 is m 20 Figure 2 an ordinary plug and socket or its equivalent, connected to any suitable source of electric energy, d is the positive and c the negative conductor with their respective connections e, f, g, h, i and j to the respective coils k, I and o, thus placing each coil in circuit with the electric current through said plug. By this multiple method of operating the coils there is practically no limit to the 25 magnetic influence that can be exerted on an object, if the leads from the main line to the switch or cut-off and from the switch to the coils, or current-regulator that may be attached to the coils, has sufficient cross section and the electric current ample, the efficient limit of a single coil or of coils in series can be added indefinitely with the coils in multiple under the foregoing described conditions, 30 and the quantity and density of magnetism from them will be in proportion, practically, to the number of coils of equal power so connected, if a similar electric current is also proportionately supplied and the coiling and position of the coils themselves be in proper relation to each other as previously described. The magnetic force in both methods can be increased by increased energy in the 35 electric current supplied, and by this compounding of the coils the magnetic field can be made as dense and strong as desired. For simplicity of illustration I have shown the coils in Figure 4 adjacent to each other, but the compounding or multiple effect of the coils is greater if they are in contact and positioned upon each other, the further they are separated 40 from each other the less dense will be the magnetic field. By the term “frequency current I mean any current that has an unsteady How, for instance, the so-called alternating current. A regulator, knife switch, fuse or their equivalent may be employed on the coils connected in multiple, to open or close the electric circuit on all or each 45 singly. O V Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is: 1. In a means for treating live animal, live vegetable or other objects, the arrangement of a pliable cable coil in circuit with a frequency source of electrical energy. 2. In a means for treating live animal, live vegetable or other objects as claimed under head one, a plurality of cable coils arranged in series. 3. In a means for treating live animal, live vegetable or other objects, the 50 /► r* O)
