The piston l is drilled longitudinally and laterally with oil holes 20, allI of which communicate with the hollow center 21 of the piston bearing 1l to receive a source of lubricant supply therefrom. The movable bars 18 on the edges of the piston are likewise drilled at 22 to permit the passage of lubricant therethrough and into contact with the walls of the cylinder. Y Y
An arm 23 is provided on the bearing end of each piston l() that extends into the crank case l. The extended arm 23 on each piston is connected by a connecting rod 24 to one of the throws on the engine crank shaft. The various Athrows onthe crank shaft 2 are offset thereon in proper relation, whereby when the connecting rods 24 are connectedv to the crank shaft 2 and to the respective pistons l0, the said pistons l0 will be located in propertiming relation within each of the cylinders.
exhaust or discharge ports 58 on both of the opposite sides of the engine cylinders are connected to a common exhaust manifold 33.
- Valves 27 and 28 are slidably mounted in each of the respective inlet and outlet ports.
Each valve is slidably mounted in a bearing v V39 provided on a projecting end of the enl gine crank shaft 2. The diameters of the timinggears on the'cam shaft and crank shaft are proportioned so that the proper timing between the cam shaft and crank shaft will be maintained to open and close the various inlet and outlet valves 27 Vand 28 during each of the various cycles of operation ofthe engine. i
A plurality of standards 40 are provided along the upper end of the variousengine y cylinders adjacent the cam shaft 36. A y
rocker arm 4l is pivoted at 42 intermediatev its ends whereby an end 43 of said rocker arm will rest on the cam shaft 36 and the opposite end 44 of the rocker armwill rest against one of the valve tappets `on the lleft side of the cylinders. Thus as rthe cams on the cam shaft 36`rotate to engage the end 43 of the rocker arm, the said rocker arm is oscillated and the end 44 thereof moved into engagement with a valve tappet to open the V valve. After the pressure of the rocker arm is released from the'valve, ythel expansion spring on said valve, causes the valve to be broughtvto the normally closed position. A rocker arm 46 is pivoted to thev standard at an end 47 thereof, said last mentioned rocker arm being arranged beneath the cani shaft 36 and liavingthe free end 48 thereof in engagement with the projecting stems of the valves on the rightrside of the engine.
The rocker arm 46 is moved downwardly'by the cams on the cam shaft 36 to open the various valves andv saidV valves are returned to the closed position by the expansion springs therearound. It is obvious that ythe cams on the camshaft will be. arranged thereon in proper position to actuate the valve rocker arms to effect opening movement ofthe various valves in proper sequence in the" cycle of operation of theengine.v In accordance with standard practice, each of the combustion chambers 25 and 26 are provided with spark plugs 49 or some other type of sparking device, for igniting the combustiblel mixture in the combustion chamber.
, My engine operates on the four cycle principle, wherein on the first cycleY a charge of combustible material is d awn into the' engine cylinder; on the second cycle the charge is compressed by the action of the piston moving in the cylinder; on Vthe/third cycle the compressed combustible mixture is ignited and` on the fourth `cycle theburned products of combustion are exhausted from the cylinder. Y Q I In Fig. l of lthe'drawings a combustible mixture is confined between the piston Vand cylinder, on the left side of the engine, while a combustible charge is about 4to be admitted into the combustion chamber on the right side of the cylinder. .The movement of the piston into the dotted position shown in Fig. l causes the combustibleinixt'ure on the left side of the piston to ,be compressed and y a charge of combustible material to befdrawn into the chamber on-the right side. succeeding cycle the combustible mixture in the left side combustion chamber is ignited while combustible charge on the right side ofV On the a the piston would be compressed.` On the'V Cil next cycle the combustible charge on the right side of the piston is exploded and the products of combustion'on the left side of the piston are exhaustedjfrom the cylinder.
Gn the last cycle a charge of combustible material is drawn into ,the vcylinder on the left side of the piston While the burned prod- -ucts of combustion on the right side ofthe Ypiston are exhausted from the cylinder;
Ail)
Each of the various four Vcycles of operation are then repeated.A My experiments havey determined that an lengine constructed in accordance with rmy'f'invention will develop greater horse power per imit of fuel con sum'cd yand per weight of engine. y Y
