INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent. I Patented Application filed September 19, 1917. Serial No. 192,065.

To all whom may concern:

Be it known that I, ALFRED MoneLIN, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements inv Internal- CombustionEngines, of which the following is'afull, clear, and exact description, such as will enable others skilled in the art to. which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of ref-v erence marked thereon, forming a part of this specification.

This invention relates to internal combus-.

tion engines, and the objects of my invention are to increase the simplicity of the construction and operation of the engine, by

decreasing the number of parts of which the usual engine is composed; by lessening or avoiding the necessityfor adjustment of the various parts, and by increasing the convenience in manipulation of the engine, T 0 this end, I have made changes in this engine from similar engines; all with the object of increased efficiency. prises certain special constructions, combinations and arrangements of parts, as hereinafter set .forth. V

In the drawing, in which like numeralsof reference indicate corresponding throughout,

Figure 1 represents a; plan view partly in section of an internal combustion engine embodymg one form of my invention.

Fig. 2 represents an end view looking in the direction indicated. by the arrow in Fig. 1.

Fig. 3 represents an under plan view of the cylinders illustrating the rotary valve seats with the valves and valve casings removed.

Fig. t represents a transverse section taken on line wa2 Fig. 1 through the valve. seats and showing the valves and valve casings, and

Fig. 5 represents a side elevation partly in section of one of the rotary valves with gear attached.

Referring to the drawings, 1 and 2 represent the two cylinders secured together by means of the integral flanges 33 in any desired or convenient manner, each cylinder being open at its outer end and jacketed for cooling purposes. To the open ends of said cylinders collars 4 and 5 are secured, the

The invention eom-' parts collar -'5 having centrally secured thereto bearings 6 -6;for the reception of one of the crank-shafts i trally secured thereto bearings 88 for the reception of the other crank-shaft 9. The cylindrical pistons 28--28 are connected by piston rods 29+29 with the crank-shafts Y and 9." The collar t-is further provided with two integral extensions 101O to which 'aresecuredthe bearings 1111 for the re ception'of the rotary .valveoperating shaft 12 to which are secured the bevel-wheels 13 and 13' presently to be described;

The crank shafts 7 and 9 have each at tached thereto balancing'fly wheels 14L14L and fly wheels 15l5 connected by connectingrods l6 and 16. The crank-shaft 9 is further p-rovided with a gear wheel 17 designed to mesh with a gear wheel 18,:the diameter of which is twice as large as the gear wheel -1'Z,'said gear wheel 18' being secured to the rotary. valve operating shaft 12in order to revolve said shaft 12 once to every two revolutions of the crank-shafts 9 and 7. The under side of the cylinder 3 has formed integrally thereon ftwo valve seats 19-19 are designed to receive the rotary valves;

2121 to the ends ofwhieh are secured the bevel wheels 22-22 adapted to mesh with the bevel wheels iii-15 on the rotary valve operating shaft 12, Each rotary" valve: is provided with a passage or port 23 one end of the passage 24 registering with a port 25 in the cylinder 3 and the other end of the passage 26 which is located diametrically opposite to the first named end of the passage in one case registers with a port 27 shown in dotted lines in Fig. 3 which represents the port in the valve casing 20 and which is connected with the gas supply pipe not shown. And in the other case the end of the passage 26registers with a similar port and collar 4% having cen- 27 also shown in dotted lines to indicate the ders by the movement ofthe pistons in the direction indicated by the arrows. This movement being the working stroke and one half revolution of the crank-shafts 7 and 9 movement of the pistons in the opposite di- 2 i l i 1,351,783

In an internal combustion engine, the combination with a cylinder having intake I and exhaust ports, said intake and exhaust ports being located in line with each other insaid cylinder, a single movable piston located in each end of said cyllnder, a rotatable crank-shaft located in bearings on 1 each end of the cylinder operatively connected with each piston, a connecting rod operatively connected to said crank-shafts, a rotary valve operating shaft mounted in bearingsonone end of the cylinder, a gear carried by the crank shaft meshing with a gear. carried by the rotary valve operating shaft for revolving said valve operating shaft once to every two revolutions of the said crank shaft, beveled gears carried by said valve operating shaft, two rotary valves fitted into a valve casing which is secured to the underside of the cylinder, each valve having a passage one for intaking and the other for exhausting charges, said passages communicating with the intake and exhaust ports of the said cylinder, and beveled wheels secured to the free ends of the rotary valves for engagement with the beveled wheels on the valve operating shaft for imparting rotary motion to said rotary valves.

for alternately registering the passages of said rotary valves with the intake and exiaust' port inv said cylinder.
