T ell'fwh'om itgna'g C me V Be ft'known thatl, (icons-n1). license, a citizen-bf the United filt ates, residing at "Cleveland, in the county of Cuyahoga and Statoi- Ohio, have invented certain new and useful Improvements. in High-Tension Discharge Apparatus,iof which the tollowing is a specification; This invention relates to electrical ap- 1o paratus and particularly to improvements for producing high'tension discharges from currents'of relatively low voltage such as 'rnay be obtained. from an ordinary electric lightwall socket. The,invention was especially designed for use in connection with therapeutical instruments, though 'it Will be understood that it is not intended to limit its usefulness to this plu'pose.' v 2c The principal object of the-invention is'to. provide an efiicient apparatus of the above ch aractei fmhichiis simple in construction compact in arrangement,- inexpensive to manufacture, and is adapted to be connected to an ordinary electric lamp socket.

In order that-the invention may be clearly understood, reference will he had to thenccomp'anying drawing which diagrammatically illustrates the same, and the novel fea tures thereof-will be distinctly pointed out in the appended claim.

Referring to the draiving, 1 and 2 repre sent conductors extending from a. plug 3 which is adapted to be connected to an ordi- 3l5 nary electric lamp socket. The'conductor 1 leads to the energizingcoil 4 of exceeding high rcsistancepassing around the iron 'core 5 ot an electromagnet, whichis suiaptcd'to attract the armature 6 carried bya spring 7,

-10 connected with the conductor 2, for automatically making and breaking the circuit in the ordinary manner. The end 8 of the energizing coil 4 by means of a wire 9, is connected to the usual adjustable contact, indicated by 10, which is adapted to normally engage the armature '6 as shown.

Leading from the end '8 of the energizing coil 4: is a wire 11, which extends to the primary Winding 12 of a high frequency coil, of very low resistance. The other end 13 of said primary winding is connected to a wire 14:, leading to a suitable condenser 15, preferably of the long fiat type, which condenser is connected to the conductor 2 by fib'ineaiis of a wire desi nated by 1. Said primary winding 12 o? the high frequency Specification of Letters retest. I

coil'preferably consists or": a. few turns of heavy wire, and 'to. its end .18 is connected the secondary winding 17 comprising many turns of comparatively fine wire, in order to obtain great intensity of current. The tree end or terminal 18 of thesecondary winding 1 of said high frequency coil is connected to a therapeutical instrument or other similar appliance requiring high tension charges for 85 etl'ective operation. *By having but a single. term nal as 18 leading from the secondary winding of thehigh frequency coil or con nection'toan instrument, it has been found in practice that the 'eiiiciency of the instrument has been greatly increased) When the plug 3 is connected to an ordi nary electric lamp wall socket, current of about 110 volts is drawn through the coin ductor 1, passes-around the iron core 5 through theenergizingcoil'e, thence from its endS through the wire 9, andby the contta'ct IC TtDLtEWimature 6, which as shown is normally in spaced relation to theend of The current then passesv so through the spring 7 to the conductor 2, thus completing the main circuit. The iron coreo upon being magnetized attracts the armature 6, thereby breaking the main circuit between 6 and 10. The instant the main g5 circuit isjbroken, the sudden interruption of theflow of the su ply current due to the breaking of the circuit, causes said current to charge the condenser 15 by passing through the Wire 16,.and' then cease while 99 the main circuit is broken between the armature G and the contact ltlyinstantly, the condenser begins discharging through the wire 16 and conductor 2, through the spring 7, then across the are between the armature e5 6 and the adjustable contact 10, by way of the wires 9 and 11 't-o'energize theprimary winding 12 of the high frequency coil, then back through the wiresliancl 1% to the condenser, which elements" constitute the con- 10}; denser discharging circuit. The moment the armature 6 is drawn to the iron-core 5fand While the main circuit. is still. broken between the armature 6' and the adjustable contacti 10, the iron core Sbecomes nonms magnetic and the spring 7 returns the arinatore to its normal position in engagement discharge Wiif ing currents e wincing of if; this liigii f eguency n creased. by inducing said. curren o the secondary winding 17, A sni me s merit connectezl to rho .i
