To all whom it may concern.'

Be it known that I, REiNHoLD H. WAP- PLER, a citizen of the United States, residing at the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Electromedical Apparatus, of which the following is a specification.

My invention relates-to an electro medical apparatus andy particularly to an improvement on the electro medical apparatus shown and describedin Letters Patent No. 581091, granted to me April 20th, 1897, the object of the present invention ,being to provide anapparatus whichis not only a pole changing, current varyingand sine curve current generator for the purposes described in the Letters Patent aforesaid, but also an apparatus in which when required, the sinusoidal shunt current employed in the treatment of the patient, may be madel and broken at predetermiiied intervals, so that while the current increases and decreases in intensity, it is also intermittently interrupted. l

In carrying out my present invention, I employ a coil, means fortaking a sinusoidal shunt current from the said coil, means for interrupting the current and means for operating both the aforesaid means, as will be hereinafter more particularly described.

In the drawing, Figure 1 is a side elevation of my improved medical apparatus. Fig. 2 is a plan of the sanie. Fig. 3 is a front elevation and section showing the contact bars and their contacts bearing against the surface of the coil and bars by means of which the shunt current is taken from the coil. Fig. 4 is a sectional elevation on line iv, Fig. 2, and Fig. 5 is a sectional elevation through the interrupter wheel and the spindle by which the same is turned.

Referring particularly to the drawing, designates a base which is preferably made of metal and'may be supported by and inclosed in a box or other suitable structure. Together with this base 10, I prefer to employ a Z shaped frame member, whose upper portion 11 is secured to the base 10 by means of the screw 111 or otherwise, the central portion 12 of the Z shaped member de-` pending froni the base 10, while preferably the portion 13 of the Z shaped member is parallel with the upper portion 11 thereof. I also employ a cylinder, indicated at 15 in Fig. 3, and made of paper, rubber or other similar insulating material and provided at Specification of Letters Patent.

its respective ends with the heads 16, 17, which are also preferably made of similar insulating material, and on the cylinder 15, a coil of suitable wire 18 is wound. The head 16 of the cylinder is provided with a con tact plate 19 .and the head 17 with ka similar contact plate 20; one end 21 of the coil 18 is connected electrically to the contact plate 19 by means of the binding screw 22, and the other end 23 of the coil 18 is connected to the contact plate 20 by means of the binding screw 24, and the contact plate 19 is provided with a binding post 25 and similarly the cont-act plate 20 is provided with a bind ing post 26, the binding post 25 being eleotrically connected to the Z shaped frame member and the base 10 by means of a wire 27 or otherwise.

On one side of the coil 18, I employ a bar 28 which is connected to the respective cylinder heads 16, 17, by means of screws 29 or otherwise, and extends parallel and also longitudinally with the coil 18. Similarly on the other side of the coil 18 is a bar 30, which is secured to thel cylinder heads 16, '17, by means of screws 31 or otherwise, and `the bar 28 is provided with a shunt circuit 4terminal or binding post28a and the bar 30 with a shunt circuit terminal or binding post 30a, from which binding posts the lead wires 29a 31a respectively of the shunt circuit are connected, the bars 28 and 30 being preferably constructed of a good conducting material.

In the central depending portion 12 of the Z shaped frame member, a shaft 32 is mounted. On this sha 32 andon one side of the depending portion 12 of the Z shaped frame member, a disk 33, preferably of insulating material, is secured and on this shaftJ 32 and on the oppositel side of the portion 12 of the Z shaped frame member, a disk 34 and the gear wheel 35 are secured.

36 designates a contact bar or oscillating member which at one end is connected by a pivot screw 37 to a spacer rod 38 with an intervening washer 39; the spacer rod 38 passes through an aperture provided therefor in the extremity of the portion 13 of the Z shaped frame member and is secured therein by a set screw 40 or otherwise and this spacer rod is preferably made of insulatin material. 41 also designates` a con tact ar or oscillating member which by meansof the pivot. screw 42 is connected at CII one eXtremity to the opposite side of the spacer' rod 38 with an intervening washer 43; At its other or upper extremity, the contact bar 36 is provided with a `pair of -spring contacts 36a, one of which isadapted to bear against the bar 28 and the other against the surface of the coil 18, and similarly the upper end of the contact bar 41 is provided with a pair of spring contacts 41?, one of which is adapted to bear against the bar 30 and the other against the surface of the coil 18. The contact bar 36 is connected to the disk wheel 33 by means of the connecting rod 44 an'd the contact bar 41 is connected to the disk wheel 34 by means of the connecting rod 45. i

46 designates a spindle passing at right angles through the base 10 and mounted and adapted to turn in suitable bearings, and on this spindle 46 a worm wheel 48 and a bevel gear 49 are secured.

50 designates an interrupter wheel which may be made'of any good conducting material and in whose periphery' there is a series-of teeth 51. The interrupter wheel 50 is adapted to fit over a conical hub 52 on the upper extremity of the spindle 46 with which this wheel engages frictionally and as will hereinafter appear, the size of the teeth 51 on this interrupter wheel and the extent of the spaces between the same, may be varied to regulate the desired period of interruption of the electric current through the apparatus and consequently with a given apparatus, a series of interchangeable interrupter wheels having different sized teeth, may be provided. I also employ a block of insulating material 53 which is secured to the base 10 by means of screws 54 or otherwise and suitably connected to this block of insulating material, cis a contact plate 55, to which latter a lead wire 56, from a suitable source of electricity, may be secured by binding screws 57. A spring I contact 58 is also lconnected to the contact plate 55 by a screw 59, as shown or otherwise, and this spring contact 58 is adapted at its free. end to bear against the 'toothed periphery of the interrupter wheel 50. I

may also provide a standard 60 fixed in the block of insulating material 54 and pro-l apparatus', I. prefer to vemploy a' spring motor, similar for instance to those employed in phonographs, graphophones and other like instruments, and as show n in the drawing, this-spring motor may comprise a casing 63 and a shaft 64, on which is also secured a gear wheel 65 and a bevel gear 66,- thebevel gear meshing with the hereinbefore ,named bevel gear 49,-an intermediate shaft soy site end of the governor shaft adapted to be engaged by the brake shoes 77 actuated through the. lever pivotally mounted at 76 'and controlled through the action of the spring 78 by means of the rod 79, which as 'is customary in motors of thisclass', is used to start and stop the motor as well as to determine the speed thereof when running.

In the hereinbefore described apparatus, the contact plate 55 is connected to one terminal of a suitable source of electricity by the lead wire 56, while the binding post 26 is connected to the opposite terminal of the source of electricity by the lead wire 56a and as will be understood, vprovided the screw 61 is in such a position that the spring 58 will not contact with the teeth of the interrupter wheel 50 and the screw 62 in such a position as to contact with'the base or bed 10, the electric circuit will be closed through the contact plate 55, the base 10, the current passing through by way of the screw 62, thence through the base to the portion 11 of the Z shaped member connected to the base, by way of the wire 27 to the binding post 25 to the contact plate 19 through thecoil 18 to the contact plate 20 and through the binding post 26 to the lead wire 56a to the negative terminal of the source of electrifcity 'and upon the motor being started, the action of the apparatus will be as described in my Letters Patent aforesaid; that is to say, a shunt circuit of varying intensity and changing polarity, the current therein being a sinusoidal curve current, will be closed through the patient by means ofvsuitable apparatus inserted therein between the binding posts .28a and 30a, this current being of greatest intensity when the contacts 36a and 41a are at the extremities of the coil and of little or no current value, as these contact screw 62 in the position shown in Fig. 4, that is, out of contact With the base l0, the circuit Will be closed from the contact plate 55- through the spring 58, the interrupter Wheel 50 and thence through the frame of the machine to and through the coil as hereinbefore described, and in so doing, the cur? rent as will be manifest, is intermittently interrupted as the spring 58 passes from tooth to tooth of the interrupter Wheel 50. The particular object of thus interrupting the circuit is in order to obtain stronger muscular contractions When these seem desirable in ,the treatment of the patient It will also be apparent that together With the functions hereinbefore described which are made possible by the apparatus herein, that it is also'capable of use in other connections Where 4different purposes are desired to be effected by the use of electric currents of a diiferent nature. That is to say, together With being adapted to be employed merelyias a rheostat or asfa sinusoidal current generator, interrupted or non-interrupted, the apparatus may also be employed to produce a current in the shunt circuit Which is either direct and interrupted or non-interrupted; for instance by making the terminals of the shunt circuit the binding posts 25 and 26, the current being interrupted or non-interrupted depending upon Whether the screw 62 is in contact With the base l0 or out of contact With the same. Then again, the ap'- paratus may be used for an undulatingcurrent Which is positive only and interrupted Ior non-interrupted for instance, by taking v the shunt' circuit from theterminal 28SL and Vthe binding post 26, it being interrupted or non-interrupted as in the ,former case depending upQn Whether or not the screw 62 is in contact with the base 10 or out of contact with the same, and furthermore the apparatus may be employed to set up an undulating current in the shunt circuit Which is negative only and this may be eifected by taking the shunt circuit from the binding post 28a and binding ipost 25 and in this case as in those to which reference has been hereinbefore made,.the current may be interrupted or non -interrupted depending upon Whether or not the screw 62 contacts with the baseA 10.
