GAS-ENGINE'.

specification of Letters raten-L l; application ined November 15,1909` .serial 39.528,182.

To allwlzcm. it may concern; i i i Bc it` known' that I, Gnonon R. MonRis, a citizen of the United States, residing at Chicago. county of Cook,v and State oflllinois, have invented certain new `and useful Im- 1` prowincnts in'Gras-Engines,y of which the followingl is a. specification. y My invention relates to improvements in gras engines,y under which designation are included' engines in which hydrocarbon vapor. as well as those iii which gasproper,L is used as the intlain'inaihle ingredient ofthe cxhlosive inixture.

provide a construction free froinobjectionahle complications by which the power cylinder may be exhausted on the vsame stroke that is produced byr an explosion and re' chiirgrcd hefore the return. stroke, so that an explosion may be made forA every stroke of Another object of the inv .ntion is to pro.- vide a. constructionby which the engine'inay hv inade double-acting and :in explosion produced for each stroke of the piston in each 'iih these ohjects'iii View my invention consists in `the novel construction and arrangement oi' parts which will he hereinafter fully described and more particularly pointed out. in the appended claims.v f

My inventii'in will be best understood h v reference to the accompnnyingr drawings fortuin;r apart of' this speiication, and in which` y i ligure l is ahorizontal section of myV improrcdeng''iie in its preferred forni,l and Fig. Q is an end elevation thereof. y

Referring nowto. the drawings, 1 desig-v nates a charge puin ing lcylinder and 2 a power cylinder. t-hefiirmer being piped to a usual check valve (.iiotshown), so that during' the outstrolic of the piston 4 a charge ton 4 is connected to andz activated by the crank .f-fcarried by sha-ft 5`I which is geared to the power shatf and adapted to rotate :it twice the speed thereof.

Mfruiiuil in the head' of the pumping cylindes I is a check valve i which leails'into a. che agi,- dif-,i rihni ing chamber S andudapted to prevent the return flow of the charge when forced 'tl1ewthiiigli hy means ofthe piston 4. VThe charge distributing chamber 8v` is connected to the Vpower cylinder 2 by' 1l provided in the" cylinder vheads 10. Check vvalves 11 vare provided in th'e pipes J to prevent return flow of tlie'charge and thel 'saine aradapted to'open when the pressure intermediate the heads thereof are valve conti'olledV exhaust ports 1Q, one of which is positionedadjacent .the piston 13 when at the end `Vof one stroke and the other adjacent said piston, when atftheend of its. other yignite the charge when coinpiessedat each l .i v vend ofthe power vcylinder 2. .shafts 15 aredisposcd perpendicular to the Y power shaft G and are geared'to the saine to l run at the saine speedl thereof, and.Y the 'cams l 16 are secured to said cam'k shafts andv stroke'. Spark Vplugs llfare vprovided to The oa n1 properly timed to aetuate thevalvedevers17' which openthevalves 1S, theV latter controlf f 5 ling thevportsf in 'the charge distributingyA .y i so l The operation'of the engine is asv follows: lr

Simultaneously with this gaseous movement one of the valves '18 is opened by' means ofr the mechanism hereinheforedescribed so that the gas may iow onward through one.

The exhaust valve v12 inthe cylinder 2 which is' disposed diagonally oppositesaid last named check valve is now opened and the atmosphere. Thisy reduces the pressure in the cylinder 2 and allows the free admission of the charge Whiehlls the cylinder siinul- 'taneouslywith the exhausting ofthe prodn vnets of coinbustion.v On the return stroke of the piston 113; the conditions willbe reversed andV the other cam operated valves 'will open,r Itv will be noted that sincel the piston .4 reciprocates at double the speed of the piston 13 a `new' charge. is provided at each stroke ofthe latter piston. y v

I. have, shown what I deem to be the referhle form of my ini-proved `engine IA products of combustion from the previous explosion are now passing therethrough into rief V c not wise-1mb@iimned'chemio'as-ihma i might be `varioiisch'anges ymade in the details of construction and arrangementv of: yparts 2 describedWithoutdeparting from my inyeni tion; and hence I desire toavail. .myself rof such 'changes' and valterations as fairly fall within the spirit `andscope of, the' appended.
