. Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed January 11, 1915. Serial No. 1,891.

To all whom it may concern:

Be it known that we, HERMAN C. Frscnrin,

- a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, and; Pn'mn P. MUSKET, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois,

7 have invented a new and useful Improvement in Physicians Electrical-Appliance Controls, of which the following is a specification. 1

Our invention relates to physicians electrical appliances and has for its object broadly the provision of an apparatus adapted to supply proper electric charges to vacuum electrodes, X-ray tubes, sinusoidal apparatus, diagnostic apparatus, cautery apparatus, and other implements and appliances of like nature- A further object of the invention is the provision of such an apparatus provided with a Tesla coil receiving charging current through proper transforming I apparatus, means being provided to accurately; positively and directly vary and control the charge received by the Tesla coil, and to .provide an eflicient and improved control for the sinusoidal, cautery and diagnostic circuits, such control bein so constructed and arranged that it will possible to deliver improper or dangerous charges to these circuits.

Numerous other objects and advantages wlll be apparent-from the following descript1on when considered in connection with the accompanying drawing, which illustrates various points in thi'scoil, wires 13, 14 and 15 lead to terminals 16, 17 and 18. The "reactance device 12 in the present instance isa soft iron core adapted when interrupted current is delivered to the circuit to interpose reactance in amount proportional to the I number of turns in'the coil 11; that is to say,

the number of effective turns in the coil 11 which "depends upon which terminal 16, 17

e substantially im- 7 nor 18 is connected with the other service wire "to complete what may be termed the primary circuit in the apparatus. Connection is made from any one of the three terminals 16, 17.0r 18 with a terminal 19 of the switch 3 when the switch is in closed position with the service wire 1 by a wire 21 connected to the terminal l9and to a movable arm 22 adapted to contact in its movement with any one of the three terminals 16, 17 or 18, suitable stops 23 being provided to limit the movement of this am. In the transformer 9 two secondary coils or series of coils generally designated at 24 and 25 are provided, one of which, the coil 25, being adapted to supply energy to the X-ray and vacuum electrodes, and the other, 24, to the cautery, diagnostic, and sinusoidal apparatus, as will be later described. A wire 26 leads from one end of the coil 25 to one side 27 of an interrupter 28, and a wire 29 leads from the other end of the coil 25 to the other side 31 of this interrupter. The interrupter 27 may have any preferred construction adapted to give the charge highand rapidly variable potential. In the present instance it is pro from the side 28 of the interrupter to one side 36 of the condenser. A wire 37 leads from the condenser 34 to one 'end of a coil 38 disposed about a reactance imposing device 39. The coil 38 is tapped in at a plurality of turns, four in the present instance 41, 42, 43 and 44. Wires 45, 46, 47 and 48 connect these sets of turns respectively to buttons or terminals 49, 51, 52 and 53 adapted to .be engaged by a movable arm 54 which is connected always by a wire 55 with one terminal 56 of the primary coil 57 of the Tesla coil 33. The other terminal 58 of this 'vided with a spark gap 32, which must be Y .coil is connected through the wire 59 and will correspondingly change the charge from the condenser 34 to the Tesla coil.

The position of the arm shown on the drawing in engagement with the button 53 which is connected to the end of the coil 38, remote from the end of the coil connected to the wirei37, interposes the maximum amount of reactance provided'in the present structure, and its movement toward the right in the figurecuts out a ortion of this reactanoe until it reaches the utton 49 interposing the least reactance. A further control of this charge is ef- 4 fected through the condenser itself, this connected. The portion of the condenser condenser being of the multiple order, having three outlet terminals 61, 62 and 63,

the terminal 62 being connected to two terminals 64 and 65 by a wire 66, and the terminal 63 being connected to a terminal 67 by a wire 68. A movable arm 69 is connected by a wire 71 with the terminal 61' and it is to this wire that the wire 37 is controlled by the terminal'6l is therefore always in the-Tesla coil charging circuit. The portion connected by the wire 62 may be added by moving the arm 69 onto the contact 64 and the portion controlled by the terminal 63 may then be added by moving the arm on to the contact 65,- which movement, by reason of the arrangement of the contacts 65 and 67, causes the arm ,69 to engage the contact 67 also. The contacts 65 and 67 arearranged in line with the pivotal axis of the arm 69'and the contact 64 is off this alinement. Three separate devices are therefore provided for connot been all that could be desired, for the condenser being located between-the reactance device and the Tesla coil and connected to the Tesla coil by a circuit over which there was no direct control, has prevented in large part the desired delicate control of the charge which 111$ present arrangement provides.

The X-ray apparatus generally designated at 72, by dotted lines, is adapted to have one end connected to the center 73 of the Tesla coil which is connected by a wire 74 with the terminal 56 and which constitutes the active pole in the X-ray circuit.

The other end of the X-ray device is con nected with an inactive pole 75, in turn connected by a wire 76 with the terminal 56 of the Tesla coil 33. A vacuum electrode indicated in dotted lines at 77 ,on the drawing, may be connected by a wire 78 with the center 73 of the Tesla coil in accordance with the usual custom.

Further description of the means of connecting the X-ray apparatus and the vacuum electrodes is not thought to be necessary, as these devices themselves form no part of our present invention. They are, however, indicated on the drawing to show how the circuits supplying proper charges to them are arranged in the present embodiment of our invention.

The other secondary coil 24:- is preferably constructed of a series of coils as follows: At the forward end a large number of turns form'a coil 79. The coil 79' may be of wire of any desired resistance. Following these coils are a series of coils (eleven) in the present instance indicated bylight lines 82 of low resistance, the lowest possible resistance being desirable. Following this in series and in series with the coils 82 is a seres of eight coils 83 which may have any desired, resistance. These coils are all connected in series with each other and each have an end connected with a series of twenty terminals arranged on the circumference of a circle and numbered consecutively 1 to 20 in actual practice these terminals being numbered 1 to 20 for convenience. The connectioh between the coils and these terminals is made by wires 84 and 85, the wires 84 (those indicated by heavy lines) having any desired resistance, and the wires 85 (those indicated by light lines) having little'or no resistance. It is from these terminals .that the charge is taken forthe cautery, diagnostic and sinusoidal apparatus and this is accomplished as will now be described. Two arms 86 and 87 in electrical contact with each other, are ivoted at the center of the circle about w 'ch the terminals 1 to 2O -are arran ed. The arms 86 and 87 are freel mova 1e about their pivot 88, the arm 86, ing of a proper length to engage any one of the terminals 1 to 20 said terminals bein spaced apart a proper distance to permit t e arm to contact with one only at one time. The other arm 87 is shorter than the arm 86 and is adapted to contact with three terminals, numbered respectively 89, 91 and 92, arranged within the"circle of contacts 1 to 20 as Wlll be later described. The terminal,

89 is connected with'one of a pair of posts 93 to which it is intended theleads to the cautery apparatus may be fastened. The

other terminal of this pairtis connected by a wire 94 with the first coil of the series 82.

It is intended that charge shall be supplied no to the cautery apparatus from any one of .the terminals 2 to 12 both inclusive, to

into this circuit, as it is cut out by connect ing the wire 94 with the wire to the terminal 2 Connection between any of the coils of the series 83 in this cautery circuit is prevented by an operating or manipulating handle 95 upon the arm 87 which prevents passage of the arm 86, the arm 86 being mounted on the pivot 88 above the arm 87.

The diagnostic apparatus is adapted to be connected to a pair of binding posts or their equivalent 96, one of which posts is connected to the wire 94 and the other by a Wire 97 with the terminal 91. This terminal is positioned to permit the arm 86 to contact with any of the terminals 2 to 16 both inclusive, the manipulating handle 95 of the arm 87 preventing introduction of the coils with the terminals 17 18 19 and 20 The sinusoidal apparatus .is adapted to be connected to apair of binding posts 98, one of which is connected by a w1re 99 with the front end of the coil 79 and the other by a wire 101 with the terminal 92, this terminal being so arranged that the arm 86 may contact with any one of the terminals 1 to 20 It will be noted that the arrangement of binding posts and their connections bring the coil 19 into operation only when the sinusoidal circuit is used, giving the sinusoidal circuit a variation in control of twenty steps, the least charge from which, that provided when the arm 86 engages the terminal 1 being supplied wholly by the coil 79. As the arm is moved successively from one terminal to the other-until it reaches the ter- -minal 20 the individual coils of the series 82 first come successively into operation until the termina l 12 is reached, after which the individual 00118 of the series 83 come successively into play until the terminal 20 is reached, the movement of the arm from each terminal to the next succeeding bringing one more coil into operation and thereby increasing the charge proportionately.

The connections in the cautery and diagnostic circuits, when the arm 86 is in contact with the terminal 1 deliver no charge as the cautery and diagnostic circuits do not require the services of the coil 79 and consequently these circuits start with the terminal 2 the cautery circuit going only through the terminal 12 and bringing suc-.

cessively the coils of the 'fective operation.

The diagnostic circuit starts with the terminal 2 and ends with the terminal 16 bringing successively into operation all of the coils of series 82 and the first four coils series 82 into efof series 83, Two stops 102 are provided to prevent disarrangement of the arms and malformation of the circuits. I The circuits provided for the various apparatus comprise the principal ones desired by medical practitioners at the present time, and it will be manifest that each of these circuits is subject to a fine and accurate control of the charges for the various forms of apparatus desired.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it Will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
