To all whom 't may concern:

Be it known that-I, TAYLOR MATSON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented anewand use- 'ful Explosion-Engine, of which'the following 1s a specification.

"My present vinvention consists of a novel construction of an explosion engine of the tandem cylinderfour cycle type in which explosions are alternately produced in each cylinder and wherein the piston in one cylinder causes an excess of explosive mixture to be delivered intermittently to both piston chambers.

It further consists of a novel arrangement and correlation of the inlet and exhaust ports for the different chambers.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illust-rating my invention, I have shown 4a preferred embodiment thereof which gives satisfactory results, al-

though it is to be understood that the various instrumentaliti'es of which my invention consists can be variously arranged and organized.

Figure 1 represents a sectional elevation of an explosion engine embodying my invention'. Fig. 2 represents an elevation of a detail thereof. n Similar numerals of referenceindicatecorresponding parts in the figures. v

Referring to the drawmgs, 1 designates the engine casing in which is mounted'the crank shaft 4 2 which is connected by means of the crank 3 with the lower or inner piston 4 in the usual'manner, said piston -4 be- 4o .ing adapted to reciprocate inI the lower piston casing. l

6 designates a piston rod one end ofwhich i's 'adjustably' secured to the lower piston .4, the other end/ thereof being adjust-,ably lsecured to the upper or outerfpiston 7 located in the upper piston chamber 8, it being noted that the outer and inner piston chambers and 8 are separated by a plate or diaphragm 9 and that the piston rod 6 passes through the diaphragm a9 and is provided with a* stuffing box if desired.

etV

`10is the air inlet, 11 the gas inlet and 12 the mixing chamber from which llatter the explosive mixture may pass to the conduits 13,

14 and 15. The conduit 14 leads to the porty 16 communicating with the outer end of they piston chamber 8 and controlled by an inwardly opening valve 17 provided with aspring 18 for normally maintaining the same closed. The conduit leads to the inner end of the `chamber 8 and is controlled byl an inwardly opening valve 19 Which is, normally maintained closed by a sp1-ing 20. The conduit 13 leads to the port 21 and is controlled by an inwardly opening valve 22 which is normally maintained closed by u spring 23. y

.24 designates a conduit communicatin with `the outer end of the chamber 8y an provided at this end with an inwardlyo ing valve 25 normally maintained close by a spring `26, said conduit24- also communicating with the outer end of the chamber 5 and provided at this end with an inwardly opening valve 27 normally maintained closed by a spring 28.

29 designates a conduit provided Withan outwardly opening check valve 30and oom- 'municating with Vthe conduit 24.

31' designates an exhaust outlet leading from port 16 and controlled by an inwardly opening valve 32haviug a stem 33 which has mounted thereon an adjustable collar 34 between which land the exhaust. conduit 31 is interposed a spring 35. i

36 designates a roller carried by the stem 33 and coacting with a cam 37 mounted on a shaft 38 journaled in the casin 1.

39 designates'an exhaust conuit leading from the conduit 21 and provided with an inwardly opening valve'40 having a stem 41 which carries a roller42 adapted 'to coact with a cam 43 mounted on the shaft 3S.

" 44 designates a set collar on the rod 41 between which and the conduit 39 is interposed a spring 45.

46 designates a gear mounted on the shaft 38 which meshes with a gear 47 mounted on the crank shaft 2.

k48 and 49 designate water cylinders .8 and 5 respectivel '50 designates the spark plug.

y lThe operation is as follows :-v-Tl1e explosions in the different cylinders take place nltcrnzll'ely. Assuming the parts lo be in the 105 position seen 1n Fig. 1. an explosion has lust ytaken place 'in the cylinder 5 and as the plsto'n 7 f is drawn down by means vof the connectlng rod 6 an explosive nnxture 1s then drawn through the inlet val-ve 17 into the H0 eo l jackets for the A cylinder 8.
