application. August 29, 195o, serial No. 182,055 s claims. (c1. sit-21e) This invention relates toi new and. useful viamprovernents in magnetoelectric shocking devices.

One object of the present invention is to profl vide in a magnetoelectric shocking device novel means for affecting the magnetic iield thereof to thereby affect the shocking quality of the device.

Another object of the present invention is to provide with a, magnetoelectricjshocking Adevice means interchangeably utilized therewith and whereby the normal current pulsations may be increased to thereby facilitatedly adapt same for a variety of uses. 4

Another object of the presnt inventionv is to provide a magnetoelectric shocking device which is so constructed that when utilized for operating therapeutic devices it mayr bey initially setup so that a certain shocking quality,7 and none higher,

may be obtained therefrom,` thereby preventing bodily injuries by ones ignorance of the poten tialities of such devices.

Another object of the present invention is to provide a magnetoelectric shocking device or such construction that same may be iacilitatedly disabled to prevent operationv thereof by any unauthorized persons.

Still anotherfobject of the presentinvention is to provide with a magnetoelectric shockingdvice`- a plurality of horseshoe magnets whichu may be interchangeably and combi'n'ationallyA utilized therewith in order to affect the shocking quality ofthedevice.

For further comprehension' of the invention, and of the objects and advantages thereof, refer-` ence will be had to the followingU description and accompanying drawings, and to the appended claims in which the variousnevelj-features` of: the invention are more particularly lset forth.

In the accompanying drawings forming a' ma'- terial part of this disclosure:

Fig. l is a plan view of the" device ofthe invention.

Fig. 2 is a front elevational view oi thedevice.

Fig. 3 is a right-hand side elevationall View.

Fig. 4 is an elevational View' of thev interrupter", per se.

Fig. 5 is a fragmentary view of the device con structed in accordance with a modication of the present invention.

Fig. 6 is an elevational view of amodied form of interrupter.

Fig. '7 is a diagram illustrating thewiring o'f the device.l

The magnetoelectric shocking device, according to the first form of the invention shown in Figs. 1 to 4, includes an armature housingV I6, which comprises magneticfront" and rear members Il and l2, respectively, andr non-magnetic left and right side members l3and t4, respectively, all of which are mounted on' a Woodenv base'l l5. Provided for being turned in s'ai'd housing on trundles t6 and l1' which arefournalledfin and 2 extend through thev respectivepnesof the side members i3 and I4 is an armature k Secured on the right' trundle lI1 just outwardly of the right side member 141s a- ,spur` gear I S which meshes with and is driven by a gearZll fast on a driveshait 2l journalled between the side members i3 and i4. Said drive shaft 2lv is arranged toA be rotated manually by a crank 22 secured to theright hand extremity thereof.

Threadedly carried onthe kextremity ofthe right trundle l-'l ,and maintainedy secure thereen by a knurled nut 23 is aninterrupter 24 which comprises' a current conductive disc 25,'an Ainsulative discl 26', andra plurality` of contactpoints 21 passing through said insulative disc from the 1 conductive disc.

` trundle i6 is a commutator 3|. A leaf spring' 32 secured to' a conductive lug 33 mounted on the base l5 is arranged to cooperate Withthe commutator' 3 l.` Also,V secured inthelugV 33 is a terminai' at.

Mounted on the base l5` at' the` left side endl thereof is an upright member' 35; Secured atop the upright member is ani electric light 36 having terminals 31 and 38. A- wire 39v inter-v connects the terminal 3-1 with the aorem'en-e tioned terminal 34 and another wire 4f)- interconnects@ the terminal 3`8 with the other aforementioned' terminal 30.

Fitted in the upright member 35 is a plug 4i having terminals 42 and 43'. A wire 44 interconnects the terminall 42 withy they terminal 34 and another wirev interconnects the terminal 43 with the" terminal 3o.

Now, provid df with the present arrangement is a permanent horseshoe' magnet 46 which is such that it may be simply placed on the front and rear members lan'd Ifl when the device is'to be utilized and'm'a'y be removed when it is' to be disabled-" A Ihejjust described arrangement is such' that.' turning o the crank 2'2 effectsthe induction of a current the'arrnature I8". This current is taken oi the commutator 3l by the spring 32"'. 'Iheife-` afterthe current Yis delivered bythe wires 3e. and 44;` tdth" light 36 andthe' plug.' lglespectfvly.

Nw, withrefrence ytof Fig. T aisle, itis to te seen that the interrupterco-ntact peints;` zTVa-re" greunjd; and beforetne'eireuitsjtrirougii trie'irgiit and plug; are complete the spring 2t' must' Contact withsaid pointsc- Also; the cui sinduced intheV armaturen' riormaiiy or' a purs i nature.` This pulsating current will" be i rented stur further by ,there yning ofi-the, interrupt'er anuL wur be muon suitablezfor the 3 operation of certain therapeutic and other devices.

It will be seen that the mentioned light 35 will blink or iiash on and off in accordance with both the normal pulsations of the induced current and the pulsations effected by the mentioned interrupter. Thusly, an operator may visually ascertain the shocking quality of the current being produced and knowing such may turn the crank 22 at a rate of speed in accordance with a desired quality to be obtained. j

Further, the described arrangement is desirable in that a magnet of any prescribed strength may be employed therewith when the device is setup to assure against the provision of a shocking effect greater than that of a prescribed quality. Also, the device may be disabled simply by removing the magnet, and in this way its operation by unauthorized persons is prevented.

As seen in Fig'. 5, a plurality of magnets 50 may be utilized separately or combinationally with the present device and in this way the shocking quality may be further aiected to be in accordance with a prescribed need.

As seen in Fig. 6, a modified form of interrupter 53 provides both circular contact points 54 and elongated contacts 55. 'Ibis modification alters the normal pulsating of the current in a dual manner and renders it more applicable to certain other uses.

It will be seen that the interrupter contacts may be disposed thereon in any desired arrangement in order to provide any desired alterations of the normal magnetoelectric pulsations induced in the device.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
