T o all ,whom it may concern.'

Be it known-that I, CARL HARTMANN, a

vsubject of the Emperor of Germany, and a resident of Lancaster, county of Erie, and State of New York, have invented certain new and useful Improvements in Ignition Systems, of which the following' is a speciication.

My invention relates to ignition systems for gas engines and the like, and more particularly to a system in which both a source` of direct current, as a battery, and its cir- Referring to -the drawing, v1-1, &c., rep? resent suitable sparking lgnitixcnl devices ofan engine or the like. Each-ofthese is connected by wires 242, vSnc., to contact plates 3 3,&c., l'cfa distribnter having a rotating member 4 connected' to .wire- 5, which rotating member is adapted to lr-connect the sparking devices consecutivelywith oneoi' the sources o fcurrent f v 6" represents a storage battery having'one terminal connected to-ground at 7 bymeans of wire 8, and thelothertterminal connected to one contact 9 -j.12 represents an, alternatingjcurrent dy- 'wnating curi-"ent having/one terminali contheother'terminalby means 'of wire' 14 being isalfsoxconnectedizfto*the common, contact 21 --adaptedto engage-both of therollers 39 and "'and cause them to'move alo of a switch 1 0, vb ymea'ns. of 1 v contact 3 to of a switch 22 by means of wire 23. Switch 22 1s adapted to make contact either with Contact 24 or contact 25.

represents a4 double interrupter comprising two independent interrupters, the' interrupting action of which produces a spark 1n the sparking devices, which interrupters are composed of bell crank levers 27 and 28 fulcrnmed at 29 and 30 respectively, carry ing contacts 31 and 32 respectively, adapted to make contact with contacts 33 and 34, respectively. Springs 35 and 36 normally 65 maintain the contacts 31 and 33 and 32 and 34,- respectively, closed 37 and 38 represent stationary guides havL ing surfaces alongwhich' rollers 39 and 40 are adapted to move respectively, the rollers being looselyimounted on pins 41 and 42,

respectively. Arnanged on the constantly rotating shaft-43 is a .cam 44 having two cam faces 45 and 46, bothA of which are l the guides i 37 fand38 to engage the ends 4 and 489i` the levers-27 ,and 28 respectively, to cause i the levers torotate about .theirpivots and the contacts 3 l .and33,and 32 and 34'to be 80 separated, respectively'.

.. The contacts131 and 32 are connected to klg'roundyby vmeans'ofwires 49. The contact v33. is connected to the contact 24 by means :of wire 50. Contact' 34 is connected to contact25 by means oflwire 5 1. f

As shown in the drawing, the system is supplied by' a direct currentfrom'the bats tery 6, the. primary circuit being asy follows From theoneside ofthe battery through wire 11,' 'contact 9, switch-110,1 contact '16,

wire 17, primary 18 of the vinduction coil, wire 23,` contact-21, switch 22, contact24, wire 50, lcontacts 33 and 31 of the interrupter, wires 49, to ground. The secondary 95 circuitmay be traced from lthe ground at 52 through the secondary 53 of the induction coil, wire- 5, distributer arm/4, distributer the; sparking devicel, thence to ground.

--Now, in'cas'e .it is desired to operate the system from thealternating-current source '12 the switches 10 and-22 are thrown t0.- make contact with contacts 15 and 25 respectively. `The secondary circuit supplying 1305 the' spark plugs remains .es before while the 'LTI primary circuit is as follows: From the source 12, wire 14, contact 15, switch it), contact 16, wire 17, primari7 18 'oi the in duction coil, wire 23, contact 21, switch 2:2, contact Q5, wire 51, contacts 3i and 32 of the interrupter and wires 49 to ground.

It will further be noted that4- it 'one set of contacts becomes bad or should fail for any reason, the switch Z may be thrown to connect the other set of contacts in circuit ir= lrespective of whether the switch 1Q thrown or not, that is, irrespective of whether the battery or 'alternating current source is supplying the system. It will further be noted that a single cam member operates both of the independent iliterrup ters so that the interrupter compact and more simple, and occupies a much smaller space than would be the case if separate cams on the shaft operating separate interrupters, were used.

Although I have described my improtements in great detail and with ifs'peet to one particular embodiment thereof, never- .theless I do not desire to be limited to such which produces a spark in the sparkingdel vices, switching means whereby one of said interrupters is thrown into circuit, the other interruptor may be thrown out of circuit, and a. cam operating both of said interrupters; y

An ignition system having in combination, sparking devices, an alternating current circuit and a direct current circuit, either of' which is adapted to supply the sparking devices, two interiupters the interrupting ac tion of which produces a spark at the sparking devices, one in each circuit, and a, cam operating both inter'rupters. l
