nLEoTnOTHERAPEUTIo APPARATUS! Patented Nov. 26, 1907.

i To all whom it may concern: f

Be it knownthat we, N ELs'oNIhRAYMoNn and Jessen C. Verma-citizens of the United States, residingr at Brooklyn, New York, and `York, respectively, have invented certain new and useful lmprovc ments in Electrotherapeutic Apparatus, of

which the following lis a full, clear Vand exact description. y u

Our invention relates t'oelectro therapeutic apparatus, and yparticularlyto implements mtended to be used byyhandh The object of the invention is to provide a simple and reliable apparatus the parts of which may be heldin the twoy hands, and applied to such parts of the body as may be def sired, while the current is` controlled by means operable by the thumbs of each hand. By this we do not wish itinferred that the `apparatus cannotv be used in any other way.

It 1s, however, thc most convenient.

The invention consists in improvements the principles of 'which are illustrated in the accom anying drawings. 1t contemplates 'anlin uction apparatus with a battery and co1 lThe apparatus comprises two members, I

each of which carries a suitable electrode for applying the secondary or induced current. One member contains the battery and has a controller therefor, while the other member contains the induction apparatus and has a' regulator therefor.

'Figure 1 is a View of the a paratus cmbodyino* our invention, parts oiP the same being bro :en away to show the interior construction. ,A Fig. 2 is a fragmentary longitudinal sectional View of the part of the apparatus for turning on and off the rimary cur'- rent. Fig. 3 is a cross scctionaiiview of the the secondary current, the samebeing taken on the plane of the line X-.X Fig. 1. Fig. 4 is a detail view ofthe cross bar 12. Fig. 5 is a View showing in dia am the wiring and electrical connections in both members.

1 indicates the casing of the battery member, preferably of insulating material. 2 represents a suitable form of dry battery contained therein. 3 represents one terminal of the battery. 4 is a screw taking into thefelectrode socket 5, and connecting it to the screw-threaded cap 6. 7 is a threaded ring member carried by the casing 1, and to which is connected the wire 8. 9 is a stationary contact member 'to which wire 8 is f connected. 1 0 is a plate or base removably mounted in the case 1 and affording` an abut.- ment for the spring 11, which affords trical connection withthe other terminalthe bottom Ol the cell 12 is a cross bar of insulating material, such as cbonitc through which the conducting wires pass. are screw posts rejecting from the plate 10 and to which e ectrical connection is made beneath the bar 12. The spring 11 is electrically connected to post 13. Post 14 is electrically connected by wire 15 to the longitudinally movable contact member 16. Contact is made between

members

16 and 9 by depressing the member 16v for momentar contact, or sliding it longitudinally beneat the lip of the contact 9 for a prolonged contact, for instance, as set iorth 1n U. S. Letters Patent No. 780,523. ing and closing of the simply necessary to ho hand, and apply thethumbto the contact member 16.

The other member, the induction memrimary circuit, it is ber, of the apparatus is shown at the left in l the drawing. 17 represents the casing which similarly toicasing 1, is formed of insu` lating material. 18 represents the induction coil, containin r the primary and secondary windings P an S. 19 and 20 represent the two heads of the spool of the induction member. 21 and 22 are rods rigidly connecting the heads 19 and 2O and serving as part of thel electrical circuit, the head 2() being removably secured in the casing. The two wires from the battery member pass through the cross bar 23 and are secured to the ends of the rods. 24 is a screw-threaded cap having a central opening for tho wircs Or conductor cable. .25 is a sleeve or tube longitudinally movable on the coil 18 for varying the iield. 26 is a scale member carried by thel adjusting sleeve 25 having a grooved portion guided by the rod 27. 28 is a pinion carried by the casing projecting slightly outwardly therefrom, and engaging on the interior with a rack 29, movab e with the scale and adjusting sleeve. The numbers on the scale are visible through a suitable opening. 30`rcprescnts'the armature mcmber'for the primary coil. 31 is the adjustable contact screw, having a platinum point. The primary circuit passes through the two

rods

21 and 22, through the armature 30 and contact 31, so that when the current To operato the open-A elec-

y

13 and 14,

d 4the case 1 in thel is turned on in the battery member, it is re peatedly interrupted by the action of the ar- 36 and 37 represent suitable electrodes for applying the instrument to the body. The

secondary circuit when the instrument is applied, passes from the electrode 37, through,

socket 5, cap 6, ring 7, Wire 8,

contacts

9 and 16, Wire 15, then through one of the Wires connecting the battery member to the induction member, thence through one of

therods

21 or 22 tothe sprinvcontact 32, screw 33,

. socket 34 and electrode 36, andthen through such parts of the body as intervene betweenv the electrodes- 36 and 37.

LAs the inductionmember is grasped in the.

hand, the current may be regulated by a simple movement of the thumb upon the pinion 28. By this construction, the control of the primary circuit and the regulation of the sec- 4 ondary circuit may be accomplished by simi-4 lar movement, as the two members of the instrument are 'held 1n the two hands of the operator. No confusion can thus arlse, and the primary current may be instantly turned on or oiil as desired, or the secondary current desired, at any time.

may be instantly increased or diminishedas The advantages of such an apparatus, besides those above pointedout, Will be apparent'to those acquainted with the operation and application of electro'therapeutic apparatus.

What we claim is:

1. 'As an article. of manufacture, a casing, 'a

removable cap at one end thereof, a battery contained AWithin said casing, a base plate, a spring interposed between the base plate and said battery, binding posts carried by said plate, a second cap removably secured to said casing and having a perforation for the passa ev of electrical conductors.

- 2. n a device of the character described, a

combination of a casing, a battery member contained therein, a llongitudinally movable contact member carried by said casing for controlling the battery current, a plate mounted in said casing, binding post carried thereby, and a removable cap carried by said casing having an opening for the passage of electrical conductors.
