VALVE MECHANISM FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Aug. 17, 1915.

. Application. fiied April 24, 1914; Serial No. 834,121.

To all whom it may concern a Be it known that I, ADAM. Ecnnn'r, a citizen of the United States, and a resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Improved Valve Mechanism for Internal-Combustion Engines, of which the following i a full, clear, and exact descrip tion.

This invention relates to an improved valve mechanism for motors and more particularly to a valve mechanism for internal combustion engines adapted forcontrolling the supply or inlet of gases to the combustion chamber which areexploded upon being compressed therein during the reoipro cation ofithe piston or -otherwise,;as well as the exhaust of the spent gases after the explosion hastaken place, as for instance, in the common l-cycle engine.

A further object of the invention is the provision of an improved valvelmechanism in which cylindrical valve chambers 01' casings are provided adjacent to the inlet and exhaust ports to'snugly and movably receive piston valves therein, while novel means are provided for adjusting the valves for controlling the time at which gas is admitted to the combustion chamber and the quantity of fuel supplied. i

With the above and other objects in view, the invention resides in the peculiar combination and arrangement of parts to be hereinafter more fully described, illustrated and claimed, it being also an object to provide a device which is simple in construction, durable and efficient in operation and not likely to get out of working order.

Reference is to be had to the accompanying drawings forming a partof this specification, in which similar characters of reference indicate corresponding parts in both views and-in which- Figure 1 is a vertical sectional view through an internal combustionengine provided with my improved valve mechanism; and Fig. 2 is a horizontalsectional view on the line 22 of Fig. 1.

V In illustrating the application of my improved valve mechanism an internal combustion engine isfshowin'although the device may be adapted for any other type of engine or motor, and in the drawings the numeral 10 discloses the engine cylinder which is preferably provided with a surrounding water jacket l-llhaving continuous communication at the top and bottom as distinguished from two points at diametrically opposite points and at which points cylinder valve casings or chambers 12 are provided. The water jacket is located at the upper part of the cylinder and the lower part is flanged as shown at 13 for attachment to the usual crank case, there being the usual piston 14 moving or reciprocating in the cylinder and connected by a pitman rod 15 with the crank shaft in the usual manner. A spark plug 16 is engaged in the head of the cylinder for ignition of the compressed combustible gases in the usual manner.

The valve casings 12 are formed integral with or otherwise carried by the cylinder in such a manner as to intercept the water jacket, and as shown, are provided with removable heads 13 bolted or otherwise secured to the casings proper. The inlet portis indicated by the numeral 17 and the exhaust port by the numeral 18, the same being located at diametrically opposite sides of the cylinder and communicating with the interior of the valve casings 12. Mounted in each valve casing is a cylinder or piston valve 19, the samesnugly fitting the casings and having reduced end portions 20. Any

suitable means for lubricating these valves may be employed.

' The supply pipe is indicated by the numeral 21 and the exhaust pipe by the numeral 22, such pipes communicating with the valve casings at the inlet and outlet sides of the cylinder respectively. As a means for adjusting one or both of the valves to regulate the time at which the gas is admitted to the cylinder,the quantity of gas admitted and the exhaust of the spent gases, the valves are connected by adjustable stems 23 with connecting rods 24 each having a sleeve 25 engaged on an eccentric 26 of a countershaft 27 suitably driven, as from a crank shaft although any other means for reciprocating the valves may be employed. T his'is believed suiiicient for adjustment of the exhaust valve but the intake valve is provided at its reduced ends with counterbores,

the upper counterbore 28 being square to receive the squared end 29 of a combined guide and adjusting lever 30 which is 'frictionally held supported or suspended in the head 13 of the casing as by means of washers'31.

A handle or operating device 32 is provided for rotating the guideand lever as well as to adjust the valve on the threaded portion 20 of the rod 23, it being understood that the valve at its lower end is provided with an interior-1ythreaded counterbore or socket 333 for receiving the threaded end of the rod. Thus, by rotating the guide andlever 30 the valve will be rotated on the rod 23 to adjust it vertically with respect to the inlet ,port to vary the sizes thereof for the time at which the port will be opened or closed and for admitting fuel and cutting off the supply of the sameto the combustion chamber. The guide and lever 30 may be adjusted vertically to accord with the adjustment of the valve to permit the desired reciprocation of the latter, it being understood that while said device permits the valve-to be'rotated and adjusted in the man ner described, the valve is permitted to slide or reciprocate independently ofany' move-' ment'of the guide during the operation of the engine. The said stems or rods-23operate through guides 34 preferably projecting from a casting integral with the cylinder so as to guide the valves in a direct line during the reciprocation.

In the operation of an engine provided with my lIHPIOXGd'VELlVG mechanism as described, when, gas or a combustible mixture is supplied throughthe inlet pipe 21 and the valves are" in the position shown in Fig. 1; gas is admitted through the inlet portilT to the combustion chamber when the exhaust" valve is closing the exhaust port 18. On the compression stroke such gases are compressed and the valve 19 is reciprocated to close the port 17. Such gases are then ignited and the impact of the explosion reciprocates the piston, and'on the return stroke'thereof the exhaust port is opened while the inlet port is still closed and the exhaust gases pass out through the exhaust pipe 22, communication in each case being established through the valve casing 12, so that upon the exhaust port being again closed and the inlet port opened, upon the opposite stroke of the piston gas is again supplied to the combustion chamber and this operation is continued. The inlet valve is timed to properly open and close the inlet port 17 for the purpose of admitting gas through the. intake or manifold 21 into the cylinder and by turning the lever 32 the valve may be rotated on its stem and ad justed longitudinally with respect thereto and the valve. casin in such amanner as to control the exteiit to which the valve 7 passes over the inlet opening on the compression stroke of the engine and thus serve to-time the period of supply of gas to the cylinder on the recession of the valve; The

exhaust valve is similarly constructed with the exception of the adjustment feature at the top, but such adjustment may be provided in connection withthis valve to regulate the exhaust and timing thereof if devalvessnugly fit the interior surfaces of the casings? and with the exception of the openings through theshell of the cylinder there are no possible avenuesof escape to: permit the explosions to takeplace; particularly in p the valve casing. As the reciprocationof the valves :can'be regulated to a minimum theeffect of-the explosions on the valves will be unobjectionable. 1

In order to simultaneously adapt the valve-casings or chambers 12 and the'reciprocatory valve 19 therein as air compressors, each casing isprovided with an inlet valve 35 th1'ough which air is drawn on th'e up strokes of the valves 19', and uponthe return or down strokes of these valvesair iscompressed in the casings. During-the compression action the valves 35- are closed and the air will "escape through outlet valves 36 and is conveyed by a suitable conduit 37 to the carbureter which communicates with the manifold 2'1 or directly to the manifold, the essential idea being that it isconnected with the fuel supply to thinout and carbonize the same and thus produce a'better mixture. Having thus described my invention, what I claim as new and desire tolsecure by Letters Patent is-:'

l. A valve mech-anism for internal combustionengines, embodying a cylindrical casingaa valveoperating inthe'casing and conforming in cross section thereto, a valve stem adjustably connected withthe valve, means for reciprocating the valve and external means for, adjusting the valve on the stem. r

' 2.: The combination with anengine cylinder having anfinlet port and an exhaust port of casings adj acentto said ports which are thus brought in connection with'the cylbustion engines, the combination with a cylinder havlng a piston reclprocating therein and valve casings having ports communicating with the combustion chamber of the cylinder; of heads for said casings, cylindrical valves snugly fitting in the casings, valve rods connected to the valves, means for re ciprocating the rods and valves carried thereby, one of said valves having a threaded socket in one end adjustably engaged by its respective rod and having a squared socket in its opposite end, and a guide and lever frictionally supported in the casing head and having a squared portion engaging the squared socket to permit movement of the valve independent of the guide and lever, rotation of'said guide and lever operating to turn the valve to adjust it longitudinally with respect to its port.

5. A valve mechanism, comprising a cylindrical casing, a cylindrical valve in the casing and adapted for rotation therein, a valve stem suitably guided, said valve having reduced end portions with a threaded socket in one end and a squared socket in the other end, said valve stem being engaged in the threaded socket, an adjusting member having a squared portion engaging the other socket to permit reciprocation of the valve thereon, and a guide adapted upon being rotated to longitudinally adjust the valve in its casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
