Be it known that I, GEORGE lV. Fluxes citizen of the United i ltates, resicliug t Pittsfield, in the county of Berkshire State of Massachusetts, have invented ceita-in new and useful Improvements in Electrotherepeutic Apparatus, of which the following is a specification.

The invention relates to electrotherepeutic apparatus-for the treatment ofcertsin (lisee-ses, "being designed especially to increase the circulation of the blood by electrically messaging the ai'ectecl parts; and it consists in regu liiting the frequency of operation and intensity of the electrical impulses, from a battery of other suitable electrical supply circuit, by means of e rheostet or voltagereguletoi', saidimpulses being provided; by interrupting ail electric circuit, and discharging the same into the rheostet oi" volt age regulator ancl then into an elec procoiitects electrical connection Withpositive P o tive currents.

In the drawings-Figure l is cliagz'e-rm metic View of my electrical-messa e ratus; 2 is a central, lent tion of the induotiomooil, v and frequency-regulator; Fig. 's s 1 View of the e se with lid open, showing: arrangement various parts of the eppemtus, and Fig, 4: is an edge ViSW of the electrocle.

Referring to the several views, the numeral 1 indicates e suitable case or box proviclecl With a hinged licl or top 2. case is preferably divided into tli ee ccinjoertmerits, one of which contains a suitable source of electrical supply, such a battery 3, another the induction-coil 4 the batteryswitch 5, and the frequency-regulator 3 and rheostet 7, anti the remaining one containing the cable reel 8, and the electrocle 9 when not in use.

]j;,The imluction coil l is supportetl in a yoke 10 of closed magnetic circuit, anti is provicled with an oscillatory armature 11 mounted on e steel shaft 12 which extends some distance into the'iron core of the coil. Also mounted.

on the shaft 1' isan 13 adapted break the (311 int between the two con 1 and 15; contact 1% being in connection with co te t 16 of by conel ctor 1'? and with the a soil by eouclu and" to switch-contact 5' While coi1tect' Which is" e fist spring pro'vicleclwith a platinum coutect-point 15, is electrical ()DllQC'tiOl'l wit-i the condeuser'l by coliuctor 2, hell with the battery by conductor hus completing the "battery circuit wheii' 5 which is connected to battery hy ctor is in engagement with switch-j 5'1 The moment this c'ircuitisboxhe magnetic force iii yoke 10 and the induction-coil pulls armature 11 ch parallel uith saitl yoke.

circles 50 and 51 are employed to indicate two ofmany of the ad ustments of the armature.

Conductor 20 continues from condenser 19 to contact 26 of the rheostat, which contact is connected with a resistance wire 27 which loops in and connects with all of the contacts on'the rheostat, thus giving a total of 7 8 ohms of six ohms per step, more or less as may be required. Contact 26 is connected with binding-screw 28 by conductor 29, over which' the current passes ,to racket 30; through bracket 30 and short shaft 31 to binding-screw 32 to which one wire 33 of the by way-of conductor 18 to binding-screw 43 and thence through the coil to binding-screw 44. The current also passes from contact 16,

over conductor 17 to contact; 14. The electrode is provided with a mat 9 of suitable ''absorbent material held in place by a ring 9".

Mounted on the short shafts 31 and 39,

- journaled in the brackets 30 and respeca reel upon which the cable,

"tively, and suitably insulated therefrom, is

which passes through the brass tubular handle 45 of the electrode, is woundand unwound. The reel may be of any approved construction, preferably of a window-shade roller type, with spring for winding up the cable and pawl and ratchet stop arrangements; the cable passing through the tubular handle is insulated therefrom by a bushing 46.

The rheostat being on contact 16, the full current from the coil will be discharged into the contacts 35 and 37, which are so distributed over the insulated surface of the electrode that when the absorbent mat is placed uponthem, the current will be evenly distributed into said mat, thoroughly charging the same, so that when the mat is pressed 1 against the afiected part ofthe body, the exact electrical impulse will be felt as produced by the armature movement, slow or fast (low or high) frequency, according to the adjustment of knob 24, the frequency regulator being provided with indicating marks of 100 and 1000, anda pointer 47. But when the switch-arm of the rheostata is 'moved over the contact-points thereof toward the contact 26 the voltage at the contacts 35 and 37 will be gradually reduced,

and when the switch-arm finally reaches con- It will be obvious, from the construction of the electrode, that only that part of the body in contact with the covered surface of the electrode, and within zone of electrical discharge, will be subjected to treatment, so that it is possible to massage or treat only the afiiicted part of the body.

Having thus described my invention, what I claim is:-- 1. An electrical apparatus comprising positive and negative electrodes, a suitable source of electrical supply, a single field coil winding, an oscillatory armature supported in a closed magnetic circuit, means for regulating the electrical impulses-in frequency of operation, and means for regulating the intensity of the electrical impulses. 2. An electric apparatus comprising positive and negative electrodes; a suitable source of electrical supply, asingle, field-coil winding; an oscillatory motor in a closedmagnetic yoke, and a rheostat for regulating the intensity of the electrical impulses.

3. An electric apparatus comprising posi:

tive and negative electrodes; a suitable battery or other electrical supply, a single, field-coil winding; an oscillatory motor in a closed magnetic yoke; a current interrupter, and a voltage-switch for regulating the 1ntensity of the electrical impulses, and a frequency switch. for regulating the operations of impulses.

4. An electric apparatus comprising positive and negative electrodes; a suitable source of electric supply and condenser; an

induction-coil supported in a yoke of closed magnetic circuit; an oscillatory armature;

means for normally holding said armature, a

current interrupter, and a voltage and frequency regulator.

5. An electric apparatus comprising positive and negative electrodes; a suitable battery; or supply of electricity an inductioncoil supported ina yoke of closed magnetic circuit, an oscillatory armature; means for normally holding said armature; means for regulating the movement of the armature; a current-interrupter, a voltage-regulator, and condenser.

In testimony whereof I affix my signature in presence of two witnesses.
