MEDICAL BATTERY.

SPECIFICATION forming part of Letters Patent No. 395,932, dated January 8, 1839.

Application tiled August l5, 1888. Serial No. 282,772. (No model.)

To all 'wh/0711. 'if may concern:

Be it known that I, HENRY E. \I'1E,a cit-izen of the United States, residing at New York, in the county and State of New York, have invented a new and nset'ul Improvement in Medical Batteries, ot which the following is a full, clear, and exact description.

My invention relates to electric batteries,an d more especially to that class oli batteries which are specially designed to be used in electromedical therapeutics; and the object of my invention is to produce a battery in a compact and convenient lorm which shall have all the apparatus necessary to the proper diagnosis ot a case and the treatment thereof under the general principles of electro-medical Therapeutics; and my invention consists in the construction and arrangement of parts, substantially as hereinafter pointed out.

Referring to the accompanying drawings, Figure i is a perspective view of a device embodying my invention, and Fig. 2 is a diagrammatic arrangement ot' the circuits.

In the use ol' electricity tor the treatment et' disease it is exceeding y desirable and important to have the electrical appliances arranged in a convenient and accessible torni, whereby the.practitioner may make use of electricity in various ways and can apply the various kinds ol' currents wil'lmut, delay or hinder-ance, and while many forms ot batteries have been proposed I have in my present improvement produced a battery which is comparatively simple and exeeediu gl yeonven ient, in its arrangement and by means ot which one is enabled to make use ot galvauic electricity in nearly all its conditions required in the treatment of diseases.

. In carrying out my invention I provide a bracket or stand, which may be of any suitable material and ornamented to any amount desired, so as to form not only a useful but an ornamental ottice article, and in said bracket or stand I t'orm a compartment, as A, which may be closed by a suitable door, B, and in this compartment I arrange the various apparatus to be used. The battery-cells to furnish the electric current may be arranged in the base C of the bracket or stand, or may be otherwise placed, as may be desired, although I have found it very convenient to have them arranged in the manner shown, as

they are readily accessible and are prote i^tcd rfrom the elements.

In the rear portion ot' the compartment A., I mount a plate, l), ot' some insulatingI matcrial-preterably ot hard rubber or the like and the various connections to thc batteries and circuits are secured upon the rear olf this plate, one arrangement ot' the circuits beingI shown in lfig. 2. ln the center ot' this plate is pivoted an arm, E, which is connected in the line-circuit, and arouml this central pivot are arranged a number ot.' pins, l", to each oli' which is connected one ot.' the opposite poles of two battery-cells, and between these pins and pivot is arranged a circle bearing the numbers of.' the cells.

The construction ot this device is substantially like that shown in my patent` No. Still/.951., ot April l2, i897, and need not be particularly described herein.

Attached to a suitable bimliug-post, ti, is a cord, g, having a plug, gj', adapted to tit over any one ot the pins l", and the arm E is arranged to rest upon any one ol thc pins, and t'rom this it will bc seen that any number oli' battery-cells may bc included in the circuit between the pin and the operaiing-lcvcr. as set forth in my patent betere reterrcd to. Upon one side ot' this central switch is arranged a pole-f,^l1angei', ll, which is shown as consisting ot' a pivoted plug adaptm'l to bc swungl tothe right or let't, and to bear upon two ot the pins 71 /1 7F /r on cither side thereof, and to make contact therewith in a `manner well understood, and more particularly pointed outhereinatter. This arm is pivoted between two brackets or posts, ll Il?, the 'former et which is electrically connected to the post. G, and the latter oi which, Il?, electrically connected to the lever E. Arranged below this pole-changcr are two binding-screwswplus and minus-to which the cords connected with the electrmles .I .T,which are to be used in contact with the patient, arc connected. Also, mounted. upon thetrame or plate I) is an interrupter, I, consisting o1;` a vibrating reed, I', an electro-magnet, I?, spring contact-finger I, and circuit-terminals l and If", and these are suitably connected in the circuit, as will bc described hereinafter, and an intierrupter-switch, I", is arranged above the interrupter. Upon the upper part ol` this' plate or frame are arranged a series of switches, K, having suitable contact-points, by means of which the various resistance-coils R maybe brought into or out of the circuit, and

to the left otthese switches is arranged aV switch-arm, K ,which is adapted to include the resistance-circuit. Below these switches is arranged another switching device, L, having several contact-points, by which the current produced may be rendered constant or interrupted, or maybe made to pass through theresistance-coils and millz'nnpere-meter, and below this switch is another one, M, which controls the primary circuit ot' the induction-coil X'. This induction-coil N is shown as mounted upon the base of the cabinet and to consist ot' two coils with a buzzer and contacts arranged, asis usual inv such cases, and provided with a key, n, whereby the circuit otl the se `ondary coil may be closed to act as a damper for. the primary ot' the inductorium when the primary is used.

The binding-posts" N N9 serve as connections i'or the electrodes ot' the secondary circuit, and the posts and N* serve as connections for the induction-coil.

Ni is a diagnosis-key for short-circuiting the primary of the induction-coil and enables the user to give single primary or secondary impulses.

Arranged in connection with the bracket or stand is a millampere-meter, and I have shown this as consisting ot' a box or case, O, provided with the usual adjustin g devices and binding-screws, and having a mirror, P, arranged atan inclination to the t'ace ot' the instrument, so as to reflect the condition ot the needle or pointer and enable the operator to easily read the saine. This mirror is fixed to a` moy-able ring, O', so that it may be moved to any angle about the face of the instrument. This is suitably connected by the bindingposts o o to the main battery -circuits, and switches are provided, so that it may be included or excluded troni the circuit as desired. In place of orin addition to the resistance-coils l use a water-rheostat, W, which is connected to the circuit Je by the wire nand may be connected to the circuit 7 by the switch or connector X.

In order to make use ot' thc devices thus far described, the circuits may be arranged as indicated in Fig. 2, and I will now trace the circuits, showing' the application oil the various currents to the patient and the way the apparatus described may be variously combined to produce dillferent therapeutic effects.

As indicated, each ot' the pins F is connected to one oi' the opposite poles of each of two batteries, and the cord g is connected to the plug g', (shown in the present instance as lixed upon the pin No. 1,) and thc other end ot' theA cord is connected' to the binding-post G. rlhe swinging arm E is shown as resting on the pin 27, and the other end is connected to the pivot Egand it will thus be seen that battery-cells from l to 27 are included between the binding-screw G and the pivot E. It may be stated that the plug may be put upon any one of the cells desired and the handle moved upon any other, so that any one or all or any number of cells in series may be included between these terminals. From the terminal G the circuit 1 leads to the post ll of the pole-changer, and from the pivot E the circuit 2 leads to the post H2 of the pole-ch an ger. The post H is permanently connected to one side of the pole-changer, and the projections 71.2 and 71? are also connected, and from 713 a circuit leads to the bindingpost plus of the external circuit. The post H`2 is permanently connected to the other side of the pole-changer, and the pins or studs 71 h are connected as shown, and from the stud h a circuit-wire, 3, leads to the switch L. the minus binding-post a circuit, 4, leads to a contact-pin, 5, of the switch L and to another eontact-point, (l, of the switch K', which switch is connected with the circuit 7 of the resistance R. This resistance is made up of a series of coils of various lengths and dimensions, and consequently of various resistances, and each of these is connected to a contact, 8, on one side and another contact, il, on the other, which contact is connected to another contact-piece, 10, arranged adjacent to the contact-piece S. Mounted on the contact 9 are levers or connectors K, which are arranged to bear upon either of the contacts 8 or 10 and to connect the correspon ding contact, 9, therewith. It will be seen that when any particular lever is resting upon Contact 10 the adjacent resistance-coil R is cutout of circuit; but when it is resting upon the adjacent contact, S, the current passing through the connector K is forced to pass through the corresponding resistance, R, on its way to the next contact, 9.

It will thus be seen that as vmany or as few of the resistance-coils maybe included in the circuit as desired. In the present instance the resistance-coil marked 1,000 and resistancecoil marked 20 are included in the circuit, while the others are cut out. These resist-A ance-coils are shown arranged in two rows for com'enience and compactness, and from the end ot the lower row the conductor 11 extends to one ot' the binding-screws o of the millampere-meter 0, and from the other binding-screw the conductor 12 leads to the contact-piece .lil of the 'connector L; also, from the minus binding-post extends a circuit, 14, which is connected to the Vibrating arm I ot' the interrupter, and from thence to the contact 15, from which a conductor, 16, leads to a contact-piece, 17, of the connector L, and thence when the connector is in proper position by conductor 3 to .the pole-changer and to lever E. In order that theinterrupter may be operated independent of the circuit including the patient, I connect it with the battery 2U of the induction-coil, and the conductors 27 and 23 lead therefrom to the ad- From TOO

IIO

justing-screw I", spring l, and thence by circuit 1S around the coil ot' magnet l2 to contact-point 19 ot the switch 1"', and thence by circuit 2O to the other side of battery 2o. The battery is preferably arranged in multiple arc for quantity currents, and the conductor 27 branches at 25 and passes through the primary of the induction -coil N, and thence by wire 22 to a contact, l, which may be connected by switch M to the wire 20, and thence to the other side of the battery 2li. A loop-circuit is taken from the opposite sides ot` the primary coil and connected to the binding-posts N3 Nl, by which l am enabled to use the interrupted primary circuit and get the benefit of the current due to the discharge ot' the cere of the magnet.

The secondary coil of the inductorium is connected tc the posts 1l NL, and a switch, n, is arranged to short-circuit or close the secondary circuit. A diagnosis-key, N", is arranged between the conductors 20 and 22 to open and close the primary to-produce single impulses when the switch M is open.

Suppose now it is desired to apply a current from the twenty-seven battery-cells in circuit to a patient connected to the electrodes .l J, and the operator wishes to know the relations of t-hat circuit and the current oit' that circuit to the resistance ot` the patient, (and wc will suppose all the resistance-coils in the circuit to be cut out and the millamperemeter to be included,) the circuit may be traced as follows: from the binding-post G, through the conductor 1, to the post ll, and through the pole-changer to the plusbindingpost, and thence through the electrodes to the patient and back to the minus bindingpost. From thence it passes through the conductor l to the switch K', and thence through the conueetors K and wire 11 te the inillampre-meter O, and by the circuit 12 to the contactpiece 13, thence by the switch L and conductor 3 to the pole-changer, through the contacts 7iv 71, and post H2, and by way of conductor 2 to the pivot E and leyer E through the batteries to the binding-post G. The operator will then note the indication on the millampere-meter a-nd can tell how much currentis tlowin g through the body of the patient. In order to note the resistance ot that body the circuit is traced as be fore to the plus binding-post, and from there by the conductor 2Q it passes to the contact 29, and the leyer Kis moved thereon, cutting out the patient, and thence the circuit passes through the lever K and the resistance-coils to the millampere-meter and back as before to the other side of the battery, and the operator will then cut in or out more or less ot' the resistance-coils until he gets anindication upon the 1nillamprc-metcr the same as when constant current ol any particular strength, the number of cells desired are included between the points G and E, and the circuit may be traced from G through the wire l to the pole-changer, to thepl us binding-post, through the patient to the minusI bimling-'iost, and thence by the coluluctonl to the point 5, when, the conductorli being' placed thereon, it passes through the conductor il vto the Nile-changer and back to the piyot E. l'iy means ot' the pole-changer ll the direction ot' this current maybe yaried according to the therapeutic et't`ect desired, and, as bel'ore stated, the strength is yaried by including more or less of the cells in circuit.

lVhen it is desired to treat the patient to an interrupted galyanic current, the circuit is traced as bet'ore to the plus binding-post, through the pat ient to the minus binding-post, and thence through the conductor 14 to the Vibrator I oli' the interrupt er, through the contact 15 and comluctor lo to the contact 1T, thence through the connector l) and circuit Il to the pole-changer and bachv to the pivot E, and the circuit isconst ant ly opened and closed at thc point ln order that the connection ot the interrupter may be constantly maintained, regardless of the strength ot' the current passing through the patient, l malte use ot' the battery 2o for controlling its movements, as before stated, and the circuit may be traced from the said battery through the conductor 27 to conductor 23, thence t0 the adj listing-screw 1l, through the contact-spring l5,the cmiductor 1 S, and magnet l1 to the contact-point 19, and, the switch lbeing closed on said point` thence by the conductor 2U to the other side ol' the battel' 215. ly this arrangement it will be seen that l hay@ a constant battery torce operating the interrupter, while the current passing through the patient maybe ya ried trom one extreme to the other without att'ecting the operation et' the interrupter, the speed ot' which may be adj usted as usual by any suitable means-as the adjusting-screw l, which is a yery important t'eature ot' my inycntion, especiallyin connection with the treatment ot' delicate patients.

lVhen .it is desired to malte use ot' the secondary or taradic current, t-hc patient is connected to the bindng-stafcws N N?, and the primary circuit trombat tery itl passes through the conductor 2d to the switch M, which is, in this instance, trst placed upon the contact l otl the conductor 22, including the primary olf the indin^tion-coil N, and by conductor 2T to battery, and the usual interruptor ot the induction-coil is used to make and break the prima-ry circuit.

ln order to get the ellect ot' a single impulse in one direction on the patient, the ltey N5 may be operated to open or close the primary ot' the induction-coil.

ln order to malte use ot the magnetic discharge or extra current dueto demagnetizinga core ol' a magnet, t he patient isconnected to the binding-posts Xi" N1, and the key Ni is IOO operated to close and open the circuit ineluding the battery and primary coil of the inductorium, and the extra current passes through the branch or loop circuit, including the patient.

From the above it will be seen that all the various therapeutic eltects may be produced by the Various arran gements and connections, and that without delay or conujlicated arrangements or adjustments ot' the circuits and connections. It is evident that I am not limited to the precise arrangements and constructions shown, as they can be varied by those skilled in the art without departing from the spirit of my invention.
