- The drawing illustrates a. circuit-ii e section, which embodies the principles of myinvention. In the practice of wireless telegrnphy, motor yehicle 'cquipment, and :rgr eat many other practical indus tries, induction coils of high power are becoming in pensive construction ere now in common use. As is ,well known, the powcrof a coil depends upon two iactors. the ratio of its primary to ils sccondary windings, end the magnetizing effect of its primary winding.
Within a, given size of wire this umgnetizingcffcct. of
the primary is directly proportional to the potential coil is proportional to such potential drop; In practice, however, very low potentials have generally been used in order to avoid sparking at the contacts, and secure a sullicicnt ahruptness of the primary break. It is evident thnt ii a break could be devised that would he as efliciont as the present break and work for larger voltages, itwould multiply theipower oi the coil used in the proportion that theprimnry voltqge is multiplied. In earrying outnry present invention I provide means some sudderuuus in opening the primary circuit that has hitherto been obtained. lii'hronking :llternatingcurrent circuits it is especially .neecssarythat-tho rupture he made alrruptlysince other- I wise dangerous oscillations are set up across the pith which jth e iollowingis a M Q IRCUIT BREAKER.

I traversed by theatre drawn when the contacts SUp'd-mtc.
in carrying out nly invention I aim to provide a circuit breaker.adapted to rupture the circuit within the time of'a single oscillation of an alternating current, time drawings and to the various yiews and reference signs appearing thereon in which preventing such danger. Reierringimow to the likefpdrtslaredesigneted. by the same reierence sign I wlierever they ocqu'nldenotesaframe or cashig'which 7 he i i he: ae ni r m s I borsi'aremnd'e oi insulating msiterial dearly-upon theiit spaced epn tec't springs wand 11-,
,which are directed townrd one another so as'to' lap over and make-contactg tt theinext-remities. The alternste contact springs of eachseries are connected by conduct straps so..- that when= the i:ontacti'springsare registered or contact position, a continuouscircuit'isf formed in a zig-zag path through esch oi the and.
contact springs of the entire series. The end'cdntact designated as 10 and 10 upon the drawing arcelcctrf ally connected by any suitable means, as by flexible wires 13, with terminal studs 14, 15, which extend through the walls of the casing to any desired binding ,posts on the outside thereof.
16 designate links which connect the respective rocker bars, and serve to additionally'guide and support the same. The operation is as follows: The terminal wires be i'ng connected to the studs 146ml 15, the solenoid 8 is I energized so as to depress its end of the lover 'Z'end rnoye the rocker bars'intothe position shown in :the
drawing in which a continuous circuit is formed from one, terminal stud to the other as shove described.
When now the solenoid 8 is energized, the layer 7 is oscillated to its alternate position so that thorocker bars 2 and 3 move relatively to one anbther'with 'r'heir' attached contact springs 10 and 11 which accordingly become separated at their ends along the entire length of the series. The circuit is, therefore, broken at a multitude of points, each offwhich operates with as much efficiency the single circuit breaker commonly in use, so that voltages may be employed which are asmany times greater than the usual yoltages as thenuniher of contact springs used. As above'stated oilor comprcssedair or (my other insulating medium may be employed within the receptacle 1 and a condenser .01.
condensers may .be used to minimize the spark in the usual way.
' While I have referred to my inventionas capableoi' use with induction coils and similar apparatus, I do not,
of course, desire to he limited-or restricted to this use, since the invention is of value as a circuit breaker in all relations where it is desired to interrupt ahigh potential circuit in a vibratory or in a permanent manner. By the use of the solenoidsii, 8, I am enabled to operate the circuit h'reaker' at it"remote station or point, and break circuits of high potential jthereat without the use of motors or circuit breaking machinery of any sort; 1
When this device is used as atvihrator for an induction coil, or similaizpurpose, it is evident that the movement of the contact springs is divided between the two bars so that each requires only a very slight movement in order to make an efficient break. The. movement for the en tireseriea of corirse,.no greater than for any single Contact spring, sothat the inertia of the mechanicaliy moving parts is no greater, and possibly even less,
than that of the usual circuit breaker employing-a single movable contact. in this way a. multiple break is imposed in the gfirizui't whoseaggregnte length is many times that of a sing e contact circuit breaker, and at the same time the inertia of the vibrating parts is about the same. It is ohvi ous that if a gap of the 'one position of the cuit breaker would require 16 times 16, or 256 times as much power as is required by this new device.
What I claim, is:
1. A circuit breaker comprising two series of contact springs each mounted on a support, means for vibrating said supportsln opposite directions simultaneously so as to break the circuit at a plurality of points, therupture at each point being accomplished with. twice the velocity of each otsald burs.
2. A circuit breaker comprising a pair of )nsulating bars, a plurality of contact springs mounted on each bir'n'siiid contact springs being directed toward one another and capable 0! making electrical contact with one another at bars, electrical connections between said spriugs by which they are all connected in a single series circuit whe they are in contact with one another,
rocker arms tor supporting said bars, a casing surrounding said rocker arms and lneloslng, the pars, said casing contalnlng fluid under pressure, and means for tilting the r'ocker arms whereby thecoutact springsnre slmultsne- ,o usly separated. throughout tiie series:
3. A circuit breaker comm-icing ii pair ot insulating liars rock arms for supporting said bars and imparting a relative movement thereto, and two series 0! contact sprlngs respectively joined to the bars soars to make and break contact with one another when the bars are moved. 4. Acircuit breaker comprising a pair or insulating bars, a rock arm for movably supporting said burs, insulators having grooves for gulding.sald. bars, and contact springs connected to the'respeciive bars so as to break contact with one another when the liars are moved.
5. A. circuit breaker comprising a pair of insulating hers, a rock arm tor'movuhly supporting said bars, insulators having grooves for guiding said bars, and contact'sprlugs connected to the respective burs so as to break contact with one another when the bars are moved, said contact springs being joined in a single circuit.
In witness whereof, I subscribe my signature, in the presence of two witnesses.
