` In the outer'end of eachv piston is secured 4'a ring 2 5, and to this Ais se the inner end of a t'ube-` 26, that encir` space between the two pistons forms a compression and eXplosion 'chamber,.-
pumping -spaces into 4 which the explosive compression-stroke.
Leading into each of the cylinders isan in- -let-port 28, through which the explosive mixp gov turepasses, the port being so located that during the inward compressionfstroke of the andl the f 'space between the opposite faces of the pis# tons and the heads of the vcylinder`form .8,5 .mixture is drawn as the pistons return on the piston a partial vacuum will be created in the '4 outerend of the cilinder, and as, soon as the covered t p ow through such port and fill .the

limit of its outward movement, and the inletport may be considered as one terminus of the explosion chamber. At the opposite endof the explosion-chamber is an esca eport 33 of much larger area than the et` port, andit is uncovered innadvance of the i cylinder.
- to be ignited by a spar opening of said inlet-port, so that the exp oded gases may pass more quickly from the The direct passage of the incoming explosive mixture from the inlet-port 32 to the discharge-port 33 is prevented by de- :Electors 35, which cause the incoInin gases to travel in a swirling path that will c ear the cylinder of the gases exploded by the pre-V 4 cylinders through the ports 30 into the passage or passages 31. y When the pistons reach or nearly reach thelimit of their outward movement, the exhaust-port 33 wi ll be opeed and a portion of the exploded gases willinstantly escape. Slight further outward movement will then uncover the inlet port orports 32, andthe gases willpass through said ports and strike against the deiectors 35, and traveling in a ploded gases towardthe exhaust port 33.
-On the reversal of the movement of the pistons the gases will be compressed until the las inders, are
pistons again assume the position shown in Fi 1, atwhich time the-second explosion Wi l occur. During the second inward movement of the pistons vacuums or partial vacuums will be formed in the outer ends of the cylinder, and as soon as the ports 28 are uncovered a fresh quantity of explosivecharge Will fill theouter ends of said cylinders.
In Fig. 3 is illustrated a sli ht modification of the invention, wherein-t e structure remains precisely the same as that previously described, with the exception that a suction inlet-valve 40 is arranged in communication with the assage 31'; but in this case the ports 28', eading to the outer endspf the cylat the extreme ends of said cylinders, the device operating on the suctionstroke to draw in a charge to be subsequently compressed and exploded.
It will be seen that all superfluous valves parts and simp ig. l are at the end of the inward' its opposite ends, stuffing-boxes swirling path will drive the ex sienes and other members have been discarded and that by reducing the number of working hying the contruction of the engine there is less likelihood of break downs and repairs, and at the same time by so arranging the pistons that they simultaneous move in opposite directions, respectively,
mobiles, launches, and like structures Where rspid vibration from the engine is not desir.- a e. Havin thus described the invention, what is claime is- The combination in an internal-combustion engine, of a frame, a crank-shaft 'ournaled in said frame, a cylinder arrange be-l low the shaft, said-cylinder having heads at carried by the heads, a pair of pistons arrangedin said cylinder and movable in opposite directions, respectively, tubes connected to the outer faces of the pistons and leading through said s tufling vided Into a central explosion-chamber and end pumping-chambers, inlets through which the explosive mixture may pass to the end pumping-chambers when the pistons are at the limit of instroke, ports leadin from Said pumpin -chambers and connectefgi to a port that is p aced in communication with the central ex losion-chamber', when the pistons are at the imit of outstroke, one of the-pistons controlling the inlet-port, and an exhaustport leading from the combustion-chamber and controlled by the opposite piston, the ports bein disposed, respectively, at opposite ends o said explosion-chamber, connectin -rods leading from the pistons through the tuIIular portions thereof, brackets extendin outward from the frame to points beyond the ends of the cylinder, .levers pivotedvon said brackets, the lower arms'of said levers being connected tothe rods, and upper'rods extending from the upper arms of saId levers to the crank-shaft.
