ANDREW BENKO, on NEW YORK, N. Y.

ELECTRIC APPARATUS.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed April 25, 1916. Serial No. 93,465.

To all whom it may concern.

Be it known that 1, ANDREW BENKO, a subject of the King of Hungary, and a resident of New York, in the county of New York and State of New York, have invented new and useful Improvements in Electric Apparatus, of which the following is a specification.

This invention relates to improvements in electric apparatus and particularly to the type used in producing and conveying a mild current of electricity to parts of the body.

The principal object of the invention is to provide an apparatus, wholly complete in itself, of neat appearance and susceptible of being carried in a small compass.

A further object is to provide an apparatus of this type in which the applicators may be interchanged and also in which the source of electrical energy may be removably contained so that new elements may be substituted when the older elements become exhausted.

These and other objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, form ng a material part of this specification, and in wh1ch:

Figure 1 is a side elevational view of one of the principal elements, used as a handle for the applicator and also containing a source of electrical energy, as made in accordance with the invention. I

Fig. 2 is a longitudinal sectional view, taken substantially on the center line of the same.

Fig. 3 is a fragmental sectional view, showing the same parts in another position.

Fig. 4 is a transverse sectional view, taken online el4 of Fig. 2.

Fig. 5 is a similar transverse sectional view, taken on line 55 of Fig. 2.

Fig. 6 is a side elevational view of the other main or handle portion of the apparatus.

Fig. 7- is a longitudinal sectional view, taken substantially on the center line of the same. parts being broken away to show the interior.

Fig. 8 is a fragmental sectional view of the same, taken on line 88 of Fig. 10.

Fig. 9 is a fragmental elevational view, similar to that shown in Fig. 7.; but looking from another point of view.

Fig. 10 is a transverse sectional view, taken on line 1010 of Fig. 7.

Fig. 11 is a perspective view of the apparatus, indicating the manner of its operation, and

Fig. 12 is a diagrammatic view, illustrating the several principal elements and the wiring therebetween. The apparatus comprises two tubular casngs, respectively 15 and 50, the former being provided with rolled screw-threads at its upper end, adapted to receive a cap 16, the casing having an integral end 18, against which may rest a transverse strip 19, the same being formed with the longitudinal strips 20, disposed within the casing 15, upon opposite sides and closely adjacent to the walls.

A spring contact 21 is rigidly engaged with the strip 19 and adapted to make electrical contact with one pole of a battery 22, atits lower end, the opposite pole extending through the upper end of the battery as indicated by the projection 23.

This projection is engaged with a spring contact 24, secured to the ring 25 of an in sulating element to which are also attached the extreme upper ends of the strips 20, the latter being made of conducting material, insulated by the covering 1'7.

Oppositely disposed arms 26 connect the ring 25 with the head 27 of the insulating element, the same being held in position within the casing by the screw-threaded cap 16, having a central opening through which the convex end 28 of the insulating element extends.

A terminal wire 30 is connected to the spring contact 24 in an obvious manner, a similar conducting wire 32 being connected with the strips 20, both wires being insu lated and so combined as to extend outward through an appropriately formed opening in the crown or head piece 28, of the insulating element passing together in the form of a cord 33, to the other handle element of the apparatus as will hereafter be described.

A sliding switch knob 35 passes longitudinally through the crown 28, its lower end 36 being of reduced diameter, and split. forming two sections, adapted to spring apart and make intimate contact within a sleeve 37 when the knob is extended. (see Fig. 3) the sleeve being in electrical circuit with a washer 38, held in position by a nut to shaped end 14: of a conductor attached rigidly to the insulating ring 25 andone of the arms 26, the conductor having a sprlng arm 45 adapted to engagewith the interior of the casing 15, putting the same in circuit, and cutting the current. which fiows, when the switch is in a raised condition, to the applicator 4:3. I The raised position of the sliding switch is indicated in Fig. 3 which shows the applicator to be energized in place of the casing as indicated in Fig. 2.

The other portion of the apparatus comprises a tubular casing 50, provided with an integral bottom 51, having a central perforation therethrough, a screw cap 52 engaging with the upper end of the casing, securing in position an insulating element, comprising a crown 53 which extends outwardly through a central opening formed in the top ofthe cap 52, and having downwardly extending arms 5-1 and 55, connecting with an integral disk 56 at their bottom.

Rigidly attached to the disk is an induction coil 57 at the lower end of which is en gaged a ring 58, the coil being wound in the usual manner, and provided-with an insulating cover thereover.

lVithin the central opening of the coil is a core 59 which extends upward through the disk 56, terminating in a contact point 64:, a similar point 58 being formed on the point end of the adjusting screw, provided with a knurled head 60 and a clamp nut 61 by means of which it may be secured positively in adjustment, the screw passing through a metal bushing 62, set in the center of the insulating element 53. r

A flexible vibrator'65 is secured to the ring 56 of the insulating element, the same being operated between the contacting points 6st and 58 as the coil is energized.

1 Current is conveyed to the coil 57 through the cord 33 from the battery 22, the current first passing through a switching device, one element 66 of which is secured to the arm 55 and has a curved, laterally turned portion 67 extending below the ring 56 and contactable with an arm 68 formed on the sliding switch 69, the latter being engaged with a slide-way 7 O by which it is supported and guided.

An extension 72 formed with the sliding switch engages with a non-conducting finger '51, in such manner that when it is withdrawn, that the core 59 becomes exposed proportionately within the magnetic field in the electro-magnet, modifying the current accordingly. The electrical circuit may be traced as follows 7 From the battery 22, the current of the primary circuit travels through wires 90 and 91 and into the primary coil 93 of the in duction coil 57. The desired vibrating circuit is produced by means of a vibrator 65, placed in the primary circuit in series with wire 91. The current travels from applicator 43 through wire 92 through secondary coil 94 of induction coil 57 to shell 50 through body and thence to applicator e3. When switch 37 is closed the current will be directed from applicator 43 and sent to the shell 50. The current takes the same path in the latter case but instead of passing through 43 it will pass through shell 50 to the body.

The primary circuit is broken by means of the battery switch 73, deenergizing the induction coil 57.

' To apply'the electric current for use on the human body through the applicator 13, close battery switch 73 which energizes the coil 57 causing the electric current to flow through wire 92, through applicator 43, through the body and thence to the handle 50 which is connected to the other end of the'secondaryfcoil of the induction coil 57.

To apply'the electric current through the hands, merely throw switch 35 which diverts the current of one of the secondary wires 92 to shell 15. The secondary current in this case will then been the shells 15 and 50.

In operation, if it be desired to use the casings 15 and 50 as handles whereby a mild current of electricity may be obtained, the switch 35 is depressed putting the battery into circuit with the coil, the current being transmitted in the manner described so that if the casings be grasped one in each hand, and the vibrator be properly adjusted, the desired results will be attained.

Obviously moving the finger grip 73 moves the induction coil into or out of operation. If the sliding switch 35 be-raised and the electromagnet contacts be engaged, the current will pass to the applicator 43 and not through the casing 15.; r

The view shown in Fig. 11 clearly illustrates the use of the device which as will be seen is of a very simple compact nature and the diagram shown in Fig. 12 clearly indicates the wiring from the battery to the induction coil vibrator and connecting switch which in this view is shown to be operated by means of dispensing the applicator.

lVhile I have described and shown a preferred embodiment of the invention, it is manifest that minor modifications may be made without departing from the scope of the claims hereto appended.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1.
