ATTACHMENT FOR STATIC ELECTRICAL MACHINES.

SPECIFICATION forming part of Letters Patent No. 669,052, dated February 26, 1901.

Application illed April 24, 1900.

lTo all whom t mayconoern:

Be it known that. I, GUs'r'AvUs WERBER, a citizen of the United States, residing at 507 Fourth street northwest, Washington, District ,of Columbia, lhave invented a new and useful Improvement to be Applied te the Static Electrical Machine, ofwhich the following is a specification.

My improvement consists'of a section of some insulating material to be 'interposed in the discharge-rod of either the positive or negative 'pole of `the machine as the positive or nega-tive connection may be desired inthe treatment, the other pole being grounded. The negative pole being the one` commonly grounded I show the devicein use conhected with the positive pole, and in this position I will describe its use; and I do hereby declare that the following is a full, clear, and exact description of my improvement, such as will enable others skilled in the art to which it appertains to make and use the same.

The ultimate object of the improvement is to divert the whole current generated by the static electrical machine from the track it would necessarily take in the present construction of` the machinfe'lin using the socalled Mortonfwave or interrupted cur rent. rlhis current is called by the name of Dr. Morton, of New 'York,who,rst called attention'to itsadvantages and made'its use popular in. medicingpndanit is usedat present consistsin-leaking onlya fractional part of the current from the polewith which at. tachment lismadealgtd conducting itfto the" patient, from which it is. dissipated to the,

part ofthe currentls discharged through the machine` to the ground' by means of' sparksA playing between the terminal balls of the discharge rods, each spark causing an' interruption, the impulse of which is contonic and alterative effects of the current. Using the illustration inv Fig. 8 in the drawings submitted,butomitting myimprovementv shown at a, a part of the current is leaked from P by b and conducted to the patient at d, and thence to the atmosphere, the remainder of the current being discharged in sparks from ptonandthen'ce to the ground through f. Myzimprovement shown at al turns the Serial No. 14.181. (No modeld whole output of the machine into the human -body or otherv object interposed in the track of the current around the insulated section of the discharge-rod, and from the body it is reconducted to the extremity of the discharge-rod of the pole to which attached, and the increased tonic and alterative eiects are produced, as heretofore, by discharging it in sparks through the opposite pole to the'ground; Experience with the use of the cu rrent by both methods has demonstrated that with'the use of myimprovementl I. That the entire outputof the machinei utilized as a working current instead of a small fractional part of it at present utilized in the so-called Morton interrupted or wave current.

II. 'lhat all the current is caused to pass through that part of the body or other object interposed betweenl the electrodes delivering and re-collecting the current to be dissipated by sparks and before the intrapolarinterruptions are made. y

III. That the voltage of the working current is therefore much greaterthan when only a'fractional part of the currentris available,

`as in the present use of the interrupted current. This will obviously increase the eiectiveness of machines and will' check the necessity felt in the rpast for building machines constantly larger and larger vin size..

IV. That the tonic and altejative eiectsf, produced by the interruptions of theourrent are exerted most vigorously atv the point of exit of the 'current from the body instead of at the pointof entrance, as formerly, and may be diffused or intensified by increasing or diminishing the size of the electrode're-collecting the; current from `the bodyv or in the ma.-

terial used in its construction.

V. That by mymethod the interrupted curl rent is for the first time used under perfect control and can be made to pass from the center to the periphery, or vice versa, or in anyl ticular organ or'organs-of the body.

VI. That using the whole volume asl havedescribed the current will produce better resuits with a-less number of seances andof @wenn ...t

I attair these results by the mechanism illustrated in the accompanying drawings, in

Figures l and 2 show vertical sections oi' two. forms of the improvement. Fig. a perspective View illustrating theuse of the invention. Fig. -L is a perspective view ot' a modified arrangement.

In Fig. 3 the insulating-section is shown in position at a i), the conductor which transfers .the whole current to the patient at d, from which it traverses the lower extreniities,'pel vis, and abdomen to c, where it is collected by an electrode, recondncted through e to the extremity of the same pole ati, and discharged from p to n by sparks, causing interruptions. y

The improvement is shown in vertical section in Figs. l and 2, o to p, inclusive. The improvement consists oli a straight rod of ebonite, glass, or other insulating material as may be preferred. (Shown in Fig. l at u.) To this ebonite rod is fitted at each extremity a piece of metal, as a thimbie or cap, the thimble having a recess for receiving the rod o', while the thiniole i' at the other end has a projection i", engaging a socket in a portion carried by tho ball. p shows the terminal ball of metal similar to the one used at n in the construction of the machine and provided 'with a shoulder i'. a hali`inch or 'so in length to aticrd ample facility for the attachment of the terminal' end of the conductor transferring the current around the insulation o. This shoulder is {inished With a tema le thread to connect with fz. Fig. 2 shows also a vertical section ot the improvementv of n dilierent construction, and which l prefer, as'it will prevent multiplication cf parts, in that it may he finished so as to be used in connection with the terminal rod and ball of the dis charge-rod with which the machine is provided. u shows the section of ebonitc, to each end ot ,which a metal tip is secured ati and o. These tips are joined to the ebonite a by a male thread fitting into a female thread in the rubber or merely held iirxnly in position by a spri iig-joint or other suitable means. The edges oi these tips or shoulders do not project above the free border of the ebonite, thus reducing the length of the insuiatingsection tothe minimum.Y

35 xthe proximal end o is merely long enough to form a d urabie connection with the sliding rod in a workmanlikemanner, or it may be omitted altogether and the ebonite fitted to receive the male'thread with which the rod of thesliding pole is usually nished. The tip on the distal end t' extends a half-inch or so from the ebonite to afford 'greater facility for the attachment of terminal end of conductor delivering the current at this point and is finished with a male thread to t the female thread. cut inthe shoulder of the ball furnished with the machine. To further prekconduoting it to the machine.

vent multiplication of parts, the insulatingsection may also be used for thc usual insulating extremity of one of the (flischarge-rods, as the extremity oi the pole grounded will for the time not require such insulation. and to secure u nil'ormity both insulating ext remit ics of the dischargerods maybe made alike. lu size the insulating-rod need' be oniy thick enough to make the connections in a workmanlike manner and only tong enough tocffectually prevent a leak across the insulating-section, and the length required will vary with the diameters of the circular plates used in the constructitm oi the machine.

ln the form shown in Fig. 4- l mount thc sparking-pole p' upon an insulated rod g, which is situated sufficiently far from the main pole p to prevent the current'passing directly thereto. From the main pole 'rho electric connection b passes to the electrode d, conveying the current. to the object to he electrically treated, while the return connection runs from the electrode c, rc-collcctin-g the current to the sparking-pole lj. l`hc points of conveyance to and re-collecting thc current from the body, as shown in the cnt, arethefeetand abdomen,respectively. From p the sparks pass to the `pole n. in the wave or interrupted current'in the nmnner above described.

Fig. 3 shows the improvement n. attached to the machine and the connections made with the electrodes intriiducing the currentat the feet through d and rc-collcctingit t'rorn the abdomen through the electrode c.. whence it is reconductcd by c to i' and discharged by sparks through n to the ground. Vhcn the current is taken in at the feet? the stand-rod answers for the connection from i" to d. vWhen it is taken :it anyother point through nu electrode held in position bya bandage, n cnble made insulated wires ordinarily uracil by electricians for wiring and inclosed in a soft-rubber tube should be used both for conducting the current tcthe body and for relhe body cuil of the cables should be finished with a screwthread and tap to secure it the more firmly to the binding-post on the electrode, and

lthereby etectually avoiding accidents. Electrodes to be made to contorni to any portion of the body are.constructed ot' block-iin, thin sheet-lead, or other tlexibie metal o any shape or size,Y according to thc part. to which applied and effe :t desired. Application of cleo-- trodes directly to the skin gives the minimum of shock to the part from the interruptions. lnterpos'ing layers of cloth or using wooden electrodes increases the irritant effect in causing the current to leave the body in small sparks. The Wires composing the cable are merely to be hooked over thc metz-il parts oii the machine to which attached.

W'hat l claim as myimprovement; and desire to secure by Letters Patent, is-
