THEODORE H. VENN, 013 CHICAGO, ILLINOIS, ASSIGNOR TO VENN-SEVERIN MACHINE (30., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
INTERNAL-GOMBUSTION ENGINE.
Application filed. November 13, 1918.
To all whom it may concern:
Be it known that I, TI-Inononn I-I. VENN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful Improvements in Internal-Co1nbustion Engines, of which the following is a full, clear, and exact description.
The invention relates to internal combustion engines and more particularly to the construction of the air valves used to admit air to the crank case.
In practice, it has been found that a continuously rotating valve is more satisfacz'iory in its operation than other types of valves, and the object of the invention is to provide a rotary valve which is simple in construction and which will efficiently control the admission of air to the crank case.
The invention consists in the several novel features of construction hereinafter set forth and more particularly defined by the claim at the conclusion hereof.
In the drawings: Fig. 1 is a view, partly in elevation and partly in section of an engine embodying the invention. Fig. 2 is a transverse section of the valve showing the head in which the valve seat is formed, in elevation. Fig. 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is a section taken on line 4-4 of Fig. 2.
The invention is illustrated in connection with an internal combustion engine of the type set forth in Patent No. 1,123,406, to which reference may be had for a more detailed description of the engine. The latter comprises a cylinder 5, a combustion head 6, a crank case 7, a piston 8, a transfer port 9 for conducting fluid under pressure from the crank-case to the cylinder, a crank-shaft 1O journalled in the side-heads 12 of the crank-case and a pitman 11 between the crank-shaft and the piston. At one side of one end: of the crank-shaft, one of the heads 12 of the crank-case is formed with a cylindrical valve-seat 13 which extends from the outside of the head to the chamber in the crankcase and the axis of this cylindrical seat is parallel to the axis of the crank-shaft.
Serial No. 262,286.
in the hollow valve and acts as a bafl'le for deflecting the air from the admission port 15 to direct the air longitudinally into the chamber of the crank-case. An opening 17, aligned with the path of rotation of the induction port 15, is formed in the head 12 adjacent the valve seat 13, and, if desired, a pipe 18 may be connected to said opening so that the air passing to the valve may be taken from any desired point. The inclined wall 16 also serves as a valve closure. A gear 19 fixed to the crankshaft 10 meshes with a gear 20 fixed to the outer end or stem 21 of the valve so that movement may be directly communicated from the crank-shaft to the air admission valve.
As a result of this construction, simple gearing may be used to operate the air admission valve, and by providing a valve which has an axis parallel to the crank-shaft, a cylindrical valve may be employed to accurately control the admission of air to the crank-case.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claim, without departing from the spirit and scope of the invention.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
In an internal combustion engine, the combination of a cylinder, a piston, a crankshaft operated by the piston, a crank-case, a cylindrical valve separate from the crankshaft extending through one side of the crank-case, having an induction port in its periphery and its inner end opening into one side of the crank-case, the latter being pro vided with a cylindrical seat for said valve and an air inlet in the'seat and gearing directly between the crank-shaft and the valve.
