IN TERN AL-COMBUSTION ENGINE.

Specification of Letters Patent. Application filed December 14, 1911.

Patented Sept. 29, 1914. Serial No. 665,713.

To all whom it may concern:

Be it known that I, GEORGE G. GLoUoH, a citizen of the United States, residing at Galveston, in the county of Galveston and State of Texas, have invented a new and useful Internal -Combustion Engine, of which the following is a. specification.

The present invention relates to improvements in internal combustion engines, the primary object of the invention being the provision of an internal combustion engine provided with a novel form of rotary valve disposed in the upper r explosive chambered end of each cylinderforming a rotatable lining; therefor and provided with a port adapted to be disposed to aline with the espective intake and exhaust ports of the cylinder, in combination with means operably connected to the crank shaft of the engine for rotating the valve or valves in time.

A further object of the present invention is the provision of a concaved rotary valve disposed to fit within .the concaved upper end of the explosive cylinder, the same being so mounted as to be permitted a slight. slid mp: moven'icnt due to the contraction and expansion of the cylinder and valve, so that the necessary tight. yet sliding, connection is provided at all times between the moving parts.

A further object of the present invention is the provision of a peculiarly shaped rotary valve disposed coi'icentrically in the upper end of therespective cylinders of an. internal combustion engine, the same being so constructed as to dispense with the use of spring sliding or puppet valves, and only having one port which is adapted to be brought into alinen'ient at the proper time with the intake and exhaust ports of the cylinder.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the comarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure l is a longitudinal sectional view through an internal combustion engine composed of four cylinders. Fig. 2 is a top plan view thereof, the gear case for the timing mechanism for the rotary valves being removed as on the line 2-2 of Fig.1. Fig. 3 is a section taken on line 33 of Fig. 1 looking downwardly. Fig. 4 is a side elevation of oneof the rotary valves removed. 'Fig. 5 is a top plan view thereof. v I Referring to the drawings, the numeral 1 designates the crank casing having mounted therein the usual-crank shaft 2, while connected to and carried by the crank 'casing are the four cylinders 8, 4, 5 and 6, respectively.

Adapted to supply the desired explosive mixture or carbureted air, to the upper end 0f the respective cylindersiof the engine, is

an intake manifold 8, the branches 9 and 9, respectively being disposed in opposite or diverging directions to convey the explosive charge to the respective cylinders 3-4, and 5-6, through the branch conduits 10 and 10', and 11 and 11', respectively.

Mounted in each cylinder for reciprocation therewithin are the respective pistons 12, connected tothe crank shaft 2 through the usual rods 13. In order to properly cool the respective cylinders of the-engine the same are water jacketed as for instance at 7 and 7, or the engine may be air cooled.

Leading; from the respective cylinders are the exhaust conduits 15, 16, 17, and 18, respectively, all of which are connected to the main exhaust manifold 19.

It is to be noted that the respective heads of the cylinders are peculiarly shaped, the interior surface thereof being preferably send-globular or semi-spherical in shape and adapted to fit snugly therewithin for rotary movement, are the rotary valves 20, one to each cylinder. Each one of the respective semi-spherical end or apron 24, recessed or 25 being beveled to provide a means to direct any decarbonizing substance away from the outer face, and from between the outer face of the valve and the inner Wall of the head. There is also a port 26 being provalves 20 consists of the semi-globular or" provided with the cavity 25, the lower edge vided in the wall thereof as clearly indicated in Figs. 4 and 5, while the hollow stem 27 thereof, provided with the conduit 28, is titted for rotation Within the concentric bore or sleeve 29 of the respective cylinders. Mounted in the upper end of the sleeve 28 of each valve is a spark plugl30, while properly fastened upon the exteribr of the tubular stem 27 of each valve, isl-the hub 31 of the gears 32, all of the respective gears 32, there being one to each rotary valve, being mounted within the horizontally disposed casing 33 which is supported above the respective cylinders of the engine.

In order to rotate the respective valves in the proper time so as to permit'the intaking, compression exploding and exhausting of the gases, the gears 34 and 3 L, carried by the respective shafts 35 and 35', are connected to the two end gears 82 of the train, while the lower ends of the said shafts 35 and 35 are provided with bevel gears 36 and 36', which are in mesh with the bevel gears 37 and 37' carried and rotatable with the crank shaft 2. By this means it is evident that the rotation of the crank shaft will rotate the respective valves causing the cog wheels or gears 32 to rotate in the direction of the arrows as indicated in Fig. 2 so as to bring the respective ports 26 of the rotary valves into alinement and out of registration with the respective intake ports 10, 10, 11 and '11 of the respective cylinders of he engine, and into registration and out of registration with the respective exhaust ports 15, 16, 17 and 18, in time.

In order to provide a double ignition and to obviate any diiiiculty that may be experienced in the rotating of the spark plug 30, the auxiliary spark connections 38 in each of the cylinders is provided, said spark plug connection being of the usual construction to receive the spark plug in a locked or sta' tionary position thcrewi'thin.

It will be noted that the concaved head of each cylinder is formed as a continuation of the cylinder 4 so that the concaved valve ma be readily inserted from the lower end of the cylinder without disturbing the head packing when the head is made so )arable, it being preferable however to cast the head integral with the cylinder. Further any expansion of inder head and the concaved valve will be automatically taken care of by the slight wcdging of the valve upon the adjacent portion of the cylinder to either slide downw ardly or upwardly, the outer surface of the valve always conforming to the contacting portion of the. cylinder. By mounting the spark plug in the tubular portion of the valve, its sparking terminals are disposed to ignite the compressed carbureted air which upon its exhaust tends to cleanse the terminals, while the inrush of the fresh mix-.

the adjacent portion of the cylture tends to cool not only the heated terminals of the spark plug but the valve. By providing the lubricant distributing duct (1., the abutting surfaces of the valve and cylinder are. at all times properly lubricated, so that not only is the expansion and contraction-element dealt with in an engine of this structure, but an additional safe guard, lubrication, is provided.

A lubricating system has been shown in connection with the rotary valve, and it is evident that a force or gravity feed, or in fact any feed of lubrication, may be connected so as to supply lubricant to the outer portion, of the stems 27 of the respective rotary valves and the groove a in the outer face of the globular portions 24 thereof, so that the contacting with the upper interior face of the respective engine cylinders and the concentric bores 29 thereof will be as smooth running as is possible in an internal combustion engine. Thus the oil may be supplied from above and is permitted to gravitate to lubricate the moving parts.

What is claimed is:

1. An internal combustion engine, including a cylinder the head of which is formed semi-spherical and as a ontinuation of the wall of the cylinder and is further provided with a concentric bore, said cylinder being provided with intake and exhaust ports in the semi-spherical head portion thereof, a semi-spherical hollow valve disposed for rotation within the semi-spherical head of the cylinder and provided with a single port for registration one at a time with the intake and exhaust ports of the cylinder, the lower edge of the rim of' the valve being beveledto reduce th area of its edge and to guide the compressed and exhaust gases toward the center of the valve, said valve being further provided with a tubular shank for rotation within the concentric bore of the cylinder, said shank and valve being capable of a slight sliding movement within the head of the cylinder due to the expansion and contraction of the parts, and said tubular shank constituting a spark plug carrying element.

2. In combination with an internal combustion engine, the head of which is provided with a semi -s iherical concavity terminating in a concentric cylindrical bore, said head being provided with an intake and an exhaust port, of a rotary valve, including a semi-spherical hollow member, having a concentrically disposed hollow stem, said stem being disposed for rotation within the concentric bore of the cylinder while the outer surface of the valve member is in contact with the semi-spherical walls of the head, the lower rim of the valve member being reduced and beveled from its peripherial edge inwardly to form a directing means to prevent the introduction of 3 any foreign substances between the outer as my own, I have hereto affi zed my signasnrfaci of the valve and the adjacent porture in the presence of two witnesses. tion 0- the cylinder head, said valve member being provided with a single port for GEORGE GOLDEN CLOUGH' 5 controlling both the intake and exhaust Witnesses:

ports respectively of the cylinder. HELEN DEAN WALDRON,
