Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed November 18, 1918. Serial No. 263,052.

To aZZ whom it may concern:

Be it known that I, HENRY J. EnwArns, a subject of the King of Great Britain and Ireland, residing at Elyria, county of Lorain, and State of Ohio, have invented certain new and useful Improvements in Internal-Combustion Engines, of which I declare the following to be a full, clear, and exact description.

This invention relates to internal combus tion engines and particularly to a V-type Knight engine wherein there are a plurality of sliding sleeve valves, the object of the invention being to provide improved, simplified, unitary means for accurately operating in proper timed relation the plurality of sleeve valves. In such V-type engine there is usually provided an eccentric shaft for operating suitable eccentric arms, which in turn control the sleeves, and the object of the present invention is to provide a single eccentric shaft for operating the several eccentrics for the sleeve valves in both the right hand and left hand engine of the V- type construction, in order to simplify the construction and to condense the same as much as possible. In reducing the invention to practice to get the correct timing, it was found that the location of the eccentric shaft compared with the crank shaft of the engine and the lugs on the sleeves had to be accurately determined and the arrangement of the parts shown herein represents a practical embodiment of the invention capable of producing an operative structure with correct timing of the operation of the valves.

Further objects of this invention relate to the details of construction hereinafter set forth in the detailed description to follow. I accomplish the objects of this invention in one instance by the arrangements shown but it is evident that the same might be varied without departing from the fundamental idea of providing a single eccentric shaft in V-type rlnight motor. One structure constituting an embodiment of the invention. which may be preferred is illustrated in the accompanying drawing forming a part hereof in which Figure I is a longitudinal sectional view with the crank shaft and eccentrio shown in elevation for the purpose'of clearness. Figure II is a transverse sectional view of the engine and Figure III is a plan view of the eccentric shaft detached from the :ncechanismv Referring to the drawings, the crank casing 10 is shown as supporting a plurality of cylinders arranged in a V and constituting the right hand engine 11 and a left hand en gine 12. The engine is provided with the usual crank shaft 13 located centrally thereof, as clearly appears from Figure II, while the engine, being of the Knight type, is also provided with the usual sliding sleeves let and 15. The crank shaft 13 is provided at one end thereof with a gear (not shown) for driving a chain 16. The provision of single eccentric shaft driven by the chain 16 and operatively connected with the several sliding sleeves referred to, constitutes the essential part of my invention and, as shown herein, this eccentric shaft 20 is located sul stantially in vertical alignment with the crank shaft 13. The eccentric shaft 20 is illustrated in Figure III detached from the mechanism and has a plurality of end bear ing surfaces 21 and 22 with a set of intermediate be'arings 23, as shown. Referring to Figure I it will beseen that the central portion of the engine casing 10 has a plurality of depending brackets 24 to form bean ings 24 for each of the bearing surfaces 2 of the eccentric shaft 20. Each of the ends 21 and 22 of the eccentric shaft is supported in suitable bearings 25 and 26. It will be seen that between adjacent pairs of the bearings referred to the shaft 20 is provided with four eccentrics 27. Each of these eccentric surfaces is adapted to receive the eccentric 28 of the eccentric arm 29, which is connected at the end 30 with the lug 31 on the sleeve 14, illustrated in Figure II. It will be seen that between the end bearing 21 and the bearing 23 there are a plurality of eccentrics, one for each of the sleeve valves of two oppositely disposed cylinders of the right hand and left hand engines respectively. The proper location of the several eccentrics 27 from one end of the shaft 20 to the other has been carefully worked out and when ascertained the proper location of the shaft relative to the lugs on the sleeves, the engine may be constructed accordingly and assembled in the manner indicated.

While I have described my invention in more or less detail, and as being embodied in certain forms, I do not desire or intend to be limited to the exact location of the bearings and arrangement of the eccentrics on the eccentric shaft, or to other limitation 15 side of the crank shaft of said engine a casing provided with bearings to the number of one more than half the total number of cylinders, said bearings being located between the sets of cylinders on the 0ppo sitely disposed sides of the engine, a single eccentric shaft mounted in said bearings and adapted to be operated by the crank shaft of the engine provided with eccentrics connected to the several sleeves of said engine, a complete set of four eccentrics for two opposed cylinders being located between ad jacent bearings. I

In testimony whereof, I aflix my signature.
