This movement of each'plate Visaccomplished by means of a. bell crank lever Z, one arni of which isipivoted to the plateat l', and the other arm-of which is pivoted to a slide m, at Z2, said slide having opposite extensions m', having slide bearings at m2, upon supports n, extending upward from the base of the machine. -Each slide m, has an eccentric and itman connection o, o', with the drivin s aft b, for actuation of the bell crank ever and slide'-` late k.

When the slide plate 7c, is moved outward through the action of its bell crank lever, the valve caiier is retracted' through the action of its spring j, when'the roller thereof will lie between the lu s k. The valve e, or e', is at the same time opened through pressure of the cross bar g, against the outer wall of the gas chamber, admitting gas to the expansion chamber c', or c2, when upon the thrusting forward. of the valve carrier, which follows rapidly, the -valve will be closed under the infiuence of its spring g, and the gas compressed in the expansion chamber, lnasmuch as the movement of the valve carrier is uicker than that of the sliding piston. At t is point-.the as 1s exploded through an ignter g, which c rives the sliding 'p1ston`forward, at the same time exerting power upon the shaft l), toturn the same. .When each vsliding piston reaches the n its retraction or reversal is be un t gh the action of the cam c3, or 0*, t e roducts of the combustion or explosion o the gas are exhausted through port r. Inasmuch as the sliding 40 pistons are reversed or thrust outward alternately into contact at one end thereof with the wall of the cylinder, at each quarter turn of the shaft b, the same result is obtained from one sliding piston as from two direct acting pistons, the two pistonsbeing thus equal to four direct acting pistons. As many of these sliding istons maybe emloyed asV required fort epurpose in view, hy locatinthem at different points along the shaft grooves in the bushing being providedto, correspond, and the other necesf sary parts being duplicated. l The eccentrics o, o', upon the shaft b, are set to throw the pitman connections at each v quarter turn of said shaft whereby the valve' carriers and valves are actuated at the same time, thus doing away with unnecessary duplication of parts.

Having described -the invention, what I 60 claim and desire to secure by Letters Patent is; A. y l.k In a rotary explosive engine, a casing having a cylinderical opening provided with grooves therein separated from each other and forming expansion chambers, a central Av balance` same dimensions throughout extending entirely through the saine in register with said chambers and' having an angular relation to each other, and sliding tlianietric bar pistons ofthe same dimensions throughout Working in and extending entirely through said slots, each bar piston having endwise movement from opposite ends of its slot at different times against the peripheral wall of its expansion chamber, and cam means operating against the ends of the istons for causing the same to be successive y withdrawn within their slots and projected therefrom.
