IZTTIERNAL-GOMBUSTIQIN ENGINE.

To all whom it may concern:

Be it known that I, Fnnnnnioir SCHNEIDER,

a citizen of the United-States, and a resident ofSeattle, in the county of King and State of Washington, have invented certain new and useful Improvements in In formal-Combustion Engines, of which the following is a full, true, and exact specific tion.

My invention relates to improvements in internal combustion engines and has for its principal object to generally improve upon and simplify combustion engine construction by eliminating'all valve springs and puppet valves; by providing a cylindrical rotary valve which maybe positively geared t9 the crank shaft of the engine and which serves all the cylinders of an engine. A. further advantage of my device lies in the fact that the admission of gas and exhaust from the cylinders is positively timed at the time of construction of the engine., Still another advantage lies in the arrangement for oiling the valve and its moving parts. It is a well known fact that much. of the combustion. engine troubles lie in faulty construction or operation of the valves which are generally quite complicated and require fine adjustments.

With my improved valve, there is a mini mum of noise, shock and friction as all valve motion is rotary, which will give a very quiet operation of the engine.

Other objects will appear as the invention is more fully explained in the following specification, illustrated in the accompany ing drawings and pointed out in the appended claims.

In the drawings, Figure 1 is a plan of my improved engine with parts broken away. Fig. 2 is a sectional elevation along line a'm. Fig. 3 is an enlarged cross sectional view of the engine valve taken through the packing ring groove. Fig. 4: is a longitudinal sectional elevation of the valve showing a port and a packing ring.

Referring more particularly to the drawings, numeral 1 indicates the main cylinder casting of a four cylinder internal combustion engine- 2 are cylinder heads. Pistons 3 operate in cylinders 2 in the usual manner and are connected to a crank shaft 4: by connecting rods 5. A crank case 6 completes the standard skeleton of an ord1- nary engine. The valve casing consistsof a base portion '2' which is integral with or attached to the cylinders, a cover 8 which is lntegral with or' attached to the cylinder cap 2. The joint between the two parts of;

the valve casing is preferably located so. that the ports on each side of the valve are ontirely within one casing member: or the other. Within the valve casing is cylindrical opening in which a valve 9 fits revolubly. Intake ports 10 and exhaust ports 11 pass diametrically through valve 9 and register with intake and exhaust passages 1-2 and 13 respect1vely, which communicate with the interior of the cylinder near the top. Ports 10 and 11 may be arranged spirally or otherwise around the valve 9 so as to bring about any desired sequence of filling the cylinders and exhausting them. Passages 12 and 13 are continuations of passages 12 and 13 respectively, and connect into intake and exhaust manifolds 14 and forced outof the valve by centrifugal force through oil holes 20 beneath packing rings 16 or elsewhere. The valve terminates at one end in a. shaft 21 which is positively geared to crank shaft 4 by a chain 22 and sprockets 23 or otherwise. The charge of gas is sucked into the cylinders as usual from the intake manifold when the intake port 10 registers with passages 12 and 12,"

the valve being properly timed with respect to the piston in the cylinder. The exhaust port 11 comes into register with passages 13 and 13 at the proper time for scavengering the cylinder" after combustion has taken place, by firing in the usual mannor by spark plugs 24. It will be understood that the arrangement of ports gives the cylinders any desired timing and'arran ement of firing the various cylinders,

T e ab sence of puppet valves, springs, cams and the like gives a very simple enginewhlch will be easy running and noiseless.

1; While I haveshown a particular form of {$1 'embodiment of my invention, I am aware that many minor changes therein will read ily suggest themselves. to others skilled in the art, Without'departing from the spirit and scope of the invention, and I therefore 10 desire to avoid \being limited to the exact tension formed with a semicircular trans verse depression, the last mentioned extension and depression registering With' the first mentioned extension and depression, the depression forming a valve seat, the'exten sions, having inlet and outlet ports which communicate with the cylinder body, a hol low cylindrical valve rotatably mounted in the valve seat, said valve having straight ports extending therethrough adapted to so register at determined times with the inlet and outlet' ports, means'for supplying the insane? inlet port with a charge of explosive mixture, the valve having circumferential grooves each side the ports and oil ports communicating with said grooves and the interior of the valve, packing rings seated in the grooves, and means for supplying the hollow valve With a liquid lubricant.

2. In a combustion engine the combine tion of a cylinder body formed with a lateral extension, a head on the cylinder formed with a lateral extension fitted over and secured to the lateral extension on the cylindeif body, said extensions having registen,

ing depressions which form a valve seat, the extension having inlet and outlet ports whlch communicate -W1tl1 the cylinder body,

a hollow cylindrical. valve mounted in the I I valve seat and provided with openings extending through the valve, the circumference of the valve each side the inlet and outlet ports being grooved and provided with oil ports, cocking rings fitted in the grooves, a hollow ateral reduced portion extendlng.

from the valve, a bearing cast with the cylinder body in which the hollow lateral extension is mounted, means for supplying the rollow valve with a liquid lubricant, and means on the lateral extension for rotating the valve from the crank shaft of the enne. g1 FREDERICK SCHNEIDER.
