The object of this invention is to provide an internal combustion motor of light weight in which an explosion will occur on every down stroke of the piston thereby producing an engine with a high horse power in comparison to its weight. These and other advantages will be discussed more fully during the description of the drawings.

In the drawings; Fig. 1 represents a crosssectional view of the engine. Fig. 2 shows a sectional view as taken along the line II-II in Fig. 1. Fig. 3 is a plan view of the upper piston, seen in Fig. 1. Fig. 4 shows a sectional view of the hollow piston rod, piston 15 and valve, as taken along the line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view of a modified form of engine. Fig. 6 shows a sectional view of the engine seen in F ig. 5 and as taken along the line VI-VI, Fig. 5. Similar numerals of reference indicate corresponding parts throughout all the figures of the drawings.

In the drawings Figs. 1 and 2 are seen a pair of cylinders comprising the upper cylinder 10 and the lower cylinder 11 separated by the division wall 12. At 13 is seen a third but smaller cylinder having a port 14 near the top thereof connecting to the upper part of the cylinder 11. At the top side part of cylinder 13 is an intake port 15. Near the base of cylinder 10 is an elongated exhaust port 16 opening into the exhaust pipe 17. The wall 18 separates the exhaust pipe 17 from the intake to heat the incoming gases as will be readily understood. At 19 is seen the piston of the lower cylinder 11, while at 20 is the piston of the upper cylinder 10; these two pistons are rigidly connected by means of the centrally disposed hollow piston rod 21. The lower portion of the rod 21 has a port 22 opening into the hollow piston rod 21. At 23 is seen a nut screwed into a central threaded part of thewall 12 and against a ring 24, which seals around the hollow piston rod 21 passing through said wall 12. At 23 lower end of the hollow piston rod 21 is suitably attached or rigidly aflixed tothe piston 19. The upper end of hollow piston rod 21 enlarges at 20 to form the upper piston and containing theball valve, seen in Figs. 3 and 4, 1

consisting of a. ball 25 which is sealed and held in place by a ring 26 which is threaded and screwed into the piston 20 as disclosed This ring has overlying fingers 27' which cover the ball 25 to retain the ball in its cage as in Fig. 4.

The piston 28 for the small cylinder 13 is provided with a connecting rod 28%, driven by the eccentric 29 as mounted on the crank shaft 30 which has the usual bearing supports in the base of the motor. At .31 is theusual connecting-rod for the piston 19 andjdriven from the crank shaft 30 in the usual manner. The eccentric 29 is set a few degrees ahead of the crank as shown by the X degrees, Fig.2.

-The engine operates as follows: ,On the down stroke of the pistons 19 and 20, the .pis ton 28 also travels downwardly, but is ,setia little inadvance of the pistons 19 and-20, or the X degrees previously mentioned. Inthis downward travel, the piston 28 which on its up stroke has passed and sealedthe port 14 now passes the port 14 or so that the port 14' is opened to admit the charge of airand gas as received from the carburetor C through the port 15 and port 14 and into'the cylinder 11. Upon the upstrok of the pistons, the port 14 is closed and the piston20 in its upward travel closes the-exhaust port 16 and as the pistons 19 and 20 continue on their upward stroke the vapor in the cylinder 11 un; dergoes compression causing it to enter the hollow piston rod21 through the port 22'to lift the ball 25 and discharge into the cylinder 10 where the process of compression is con tinned. At the extreme upper positionofthe' pistons 19 and 20, thetop of the port 22 regis ters a little above the nut 23 thereby releasing the pressure in the cylinder 11 or sothat the ball 25 seatsits'elfthereby holding" the compressed charge of gaseous vapors within the upper part of the cylinder 10. At this point combustion takes place andthe pistons 20 and'19 are driven downwardly and-during this downward travel anew charge of gaseous vapor is permitted to pass through the then opened port 14 to later repeat the process of compression in the cylinder 10. When the piston passes the exhaust port 16, the burnt gases, due to the expansion that has taken place, exhaust through the port 16, there being then no pressure in the cylinder 10 and a partial vacuum being created new gases may then be introduced through the ball valve 25, As the pistons travel upwardly the process of compression and combustion is repeated Referring to Figs. 5 and 6; at seen the usual cylinder provided with a piston B; con

'necting rod D and crank shaft E. At F is a small cylinder having a piston G and a lion'- nectingrod H, also mounted on an eccentric I on its crankshaft This eccentric being a little in, advance of the crank or Y degrees as shown in Fig. 6 At K is the exhaust port leading trfom cylin'der A into the open top of cylinder F. At L is the intake port for cylindenA and at M is shown an intake manifold leading from, any suitable type of blower and carburetor. ,The operation of the engine is as follows; As the crank H reaches its ex trerne lowest ,position, the port L is opened and the port K is being closed by the piston G. The port K ,is entirely closedbefore the port L closed. VWhilethe port L is still open, the blower introduces the gaseous vapor into the cylinder and as the .pistonpomes up, the vapor is compressed andthen fired and as the piston travels down, the exhaust port is opened before the intake port is op ened, but when the port L does open, the blowerintro er main cylinder, closed and opened by movements of the small piston; a wall intermediate the superposed main cylinders passing a hollow piston rod; said hollow rod having a head as a piston for the upper cylinder and with the base of the hollow rod rigid to the top of the lower piston; and packing means around said hollow rod; said hollow piston rod having a port in the rod and a ball valve mechanism in the head of the upper piston and an exhaust port near the base of the upper cylinder,

in testimony whereof I aflix my signature.
