METHOD OF AND APPARATUS FOR ADMINISTERING THERAPEUTIC ELECTRlCITY.

SPECIFICATION forming part of Letters Patent Ne. 622,922, dated April 1 1, 1899.

Application filed December 5, 1898. Serial No. 698,277. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM P. HORTON, Jr., a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Methods of and Apparatus for Administering Therapeutic Electricity, of which the following is a full, clear, and exact description, reference being had to the accompanying-drawings.

If a high-potential induced current and a low-potential continuouscurrent be administered at the same time to the human body, the therapeutic effect is very much enhanced over that produced by either current alone.'

with the coil and thus adapted to make and break the circuit through the coil and cause it to prod uce an induced current, a governing resistance separate from the coil,whereby the current may be regulated without varying the coil, and such electrical connection that one cell locally operates the vibrator by leading through it and the coil and the other cell is on a circuit which passes through the governing resistance and the patient, but in so doing divides into two paths, one of which leads through the coil and the other through the first cell and the vibrator when closed. The inducing-coil which I use is a magnetic intensif yin g-coil,bein g but a few turns around a solid bar, and produces an extra induced current instead of a secondary current. The vibrator is operated directly by the magnetism of the core. There is a metallic sleeve surrounding the coil, which softens the induced current, reducing its jarring effect.

Now the parts and connections being as above stated, when the vibrator has the local circuit closed the current from the second cell travels along the same conductor as the current from the first cell through the vibrator and the patient receives the voltaic current from the second cell, and when the vibrator opens the local circuit the patient receives the extra induced current from the coil and the thus modified voltaio current from the second cell,which now passes through the patient and the coil. Thus at all times, whether the vibrator is closed or open, the patient receives the current from the second cell, and this is modified when the vibrator opens the local circuit by the extra induced current from the coil.

The drawings are a clear illustration of my apparatus.

Figure 1 is a plan thereof. elevation, partly sectional; and Fig. 3 isa diagram of the component parts and their connections.

Referring to the parts by letters, A represents a suitable base which is preferably the top of a shallow box at, having the sides a and the bottom a B B represent the two Voltaic cells, which may be covered by a suitable shield, (indicated by the dotted line Z) in Fig. 2.)

O is the coil, which is simply an intensifying-coil consisting of a few turns of comparativelylarge wire around a solid core a between the heads 0.

D represents the vibrator, which consists of an armature d, secured to one end of a spring-strip d, and the other end of which is rigid with a sleeve (1 This sleeveis clamped adj ustably to a stationary vertical stud d by means of a set-screw (F. This construction of vibrator, however, is not my invention.

E represents the point with which the vibrator is adapted to make or break connection.

F represents a switch for opening the circuit from the cell B through the patient, and G G represent the binding-posts with which the conductors from the patient are connected. These conductors may terminate in handles, which the patient grasps, as indicated by H in Fig. 3.

J represents the resistance. It consists of Fig. 2 is a side a set of spools of very fine wire J. These spools are connected together in series, and each spool is also connected with a head J These spools are contained within the box (1 below the base-plate A, and their heads are in the depression a in thatbase-plate. These heads are adapted to contact with the plunger carried by the knob j, which slides in a slotted platej, which is connected with the binding-post G. A washer and a nut 7' screwed to the knob beneath the platej secure the knob slidably to that plate, while a springj surrounding the shank of the plunger and bearing at one end against the plunger and at the other against the knob, gives the plunger the desired spring-pressure against the headsj The head j is also provided, which has no resistance, but is directly connected with the line.

Now when the plunger is in contact with the first spoolihat is, the one at the left hand in the drawings-the circuit must pass through all of the spools. When the knob is moved to the right one head, the resistance in the first spool is cut out, and each subsequent movement cuts out the preceding spool until when the knob is at the extreme right the total resistance is cut out. As shown in the drawings, the first three spools are of one thousand ohms resistance, and the next two of five hundred each, and thus the resistance inserted into the line may be four thousand, three thousand, two thousand, one thousand, five hundred, or zero ohms. It is to be observed that these spools are all wound in the same direction and around metallic centers, wherefore they have self-induction, which reduces and thus governs the extra induced current from the coil 0. Thus the cutting out of resistance simultaneously increases both the voltaic current and the induced current.

The electrical connections are indicated by numerals.

1 is the line from the positive pole P of the cell 13 to the coil.

2 is the line from the coil to the vibrator.

3 is the line from the point E to the negative pole N of the cell 13, this constituting the local circuit through the coil and vibrator.

4c is the line from the positive pole P of the cell 13 to the switch F.

5 is the line from the switch F to the binding-post G.

6 is the line from the binding-post G to the resistance.

7 is the line from the resistance to the vibrator, and 8 is the line from the positive pole of the cell 13 to the negative pole N of ,the cell 13 When the vibrator stands in the position shown in the drawings, the current from the cell 13 travels locally in the direction of the arrows along the'circuit composed by the line 1, the coil 0, the line 2, the vibrator, the point E, and the line b. At the same time if the switch F is closed (it is shown open in the drawings) and the binding-posts G and G are connected through the patient a shuntcirenit is established via the line 8 through the cell B via the line at through the switch F along the line 5 through the patient, via the line (3 through such portion of the resistence as the knob cuts in, and via the line 7 to the vibrator. As the resistance of this circuit, however, is several thousand ohms, while the circuit through the vibrator is pre ferably only the fraction of an ohm, the current which the patient obtains from the cell 13 is immaterial, but he obtains the full current from the cell B The current from the cell l3, traveling around the coil C, energizes its core a, and the armature is drawn toward the core, thus breaking the circuit at the point E. The cell B is thus out of circuit; but if the switch F is closed and the patient holds the handles II the current from the cell 13 passes from 1, as before, through the patient and the resist ance to the vibrator, and from thence via the line 2, the coil O, and the lines 1 and S to the negative pole 1., this passage through the coil being possible because the voltaic current from B through it has ceased. At the same time the patient receives the extra induced current caused by the magnetism of the coil which travels along the conductors f2, 7, (3, 5, 4, S, and 1 in the direction of the arrows, and thus through the patient and the resistance.

The current from the second cell is so reduced by the resistance of the patient that it does not energize the coil sufficiently to retain the vibrator, and the latter springs back by its own resilience and closes the local circuit. Thus the patient receives alternately first the voltaic current from the cell 13 and an insignificant portion from the cell 13 and then the voltaic current from the cell Bflmodified by the extra induced current from the coil C.

The cutting out of resistance, which is dis tinct from the windings of the inducing-coil increases, as desired, the quantity of current which the patient receives without reducing the induced current, and by this means a more beneficial current is obtained than where the regulation is caused by governing the electromotive force of the induced current by shielding the core, as is the usual custom, or where the regulation is such that as one current increases the other decreases.

Having described my invention, I claim-- 1. The method of administering therapeutic electricity which consists in supplying the patient alternately a quantity of voltaic current and then a quantity of veltaic current modified by the extra induced current from a magnetic coil and governing the quantity by an interposed self-inductive resistance which allows the simultaneous increasing of both the voltaic current and the induced current.

2. In a medical battery, in combination, a

In a medical battery, in combination, a voltaic cell, suitable connections whereby a current therefrom may flow through the patient, and an inducing apparatus which forms part of this circuit at the time the induced currentis taking place whereby this induced current simultaneously flows through the pa tient, and a governing resistance which is separate from the inducing apparatus.

t. In a medical battery, in combination, a voltaic cell, suitable connections whereby a current therefrom may flow through a patient, a magnetic intensifying-coil causing an extra induced current in the circuit where the voltaic current is flowing, said coil being surrounded by a metallic sleeve whereby the induced current is softened.
