INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Jone i2, 191%.

Application filed February 24, 1916. serial No. 30,112.

1 '0 all whom it-onay concern:

Be it known that I, Josnrn A. Ancniinn, a citizen of the United. States, residing at New York, county and State of New York, have invented certain new and useful improvements in Internail-Combustion Engines, of which the following is a full, clear, and exact description.

This invention relates to internal combustion engines, and has particular reference to the valves of such engines.

An object of the invention is to provide a rotary distributing valve which will he dis placed or reciprocated during its rotary movement with resultant continual polishing of its seats.

A further object is to provide adequate cooling of the valve to compensate for theadditional reciprocatory movement.

A still further object is to provide a valve of the above described construction which will he of minimum magnitude for its purpose, thereby decreasing Weight and friction, with corresponding increase in efficiency.

The invention can be readily understood from the following description taken in connection with the accompanying drawing, in which- Figure 1. is a fragmentary side elevation, partly in section, showing an internal combustion engine embodying my improvemcnts.

Fig. 2 is a fragmentary side elevation, partly in section, showing a modified form of the invention.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a cylinder which is provided near its upper or outer end With an exhaust port 11 and an admission port 12. The cyilnder is provided with a Water jacket 18. A sleeve valve 14 is mounted coaxial with and outside of the cylinder and rotates on the Wall of the Water jacket and flanges iii--16 thereof, as a seat. In the valve is provided a port 17 which registers alternately with the ports 11 and 12. The valve is rotated continuously to cover or uncover the inlet and exhaust ports in the cylinder in proper sequence, by means of a gear 18 on.

the valve, and in the resent embodiment this gear 1s shown as being driven at a posi tive ratio from the crank shaft 19 of the enine in means of a shaft 20' geared to the (fii'giifdii shaft and to the gear 18 as shown.

. relatively to the Druring rotation the valve is fiisplaced or reciprocated to continuously polish the seat thereof, and this reciprocating movement may be accomplished in any preferable Way, but for convenience I have shown a projection 21 formed on the seat 15 of the valve, the projection operating in a cam Way 22 on the also and serving to lift the valve at times during its rotary movement. To make the return stroke of the valve positive, the valve may be formed with a projection 23 which operates in a cam Way 24 on the seat 16. Or shown in 2,1 may form cam way. in the nature of a groove, in which operates a projection in the nature of a pin on the valve 5/7.

In order to reduce the magnitude of the valve to a minimum, as shown in Fig. 2 the cylinder is decreased or reduced in diameter, as shown at 28, oeyond the limit of stroke of the piston 2-9, and the exhaust and admission ports 30 and 3]. are located. in this reduced end of the cylinder. The continuously rotated valve 32 surrounds this reduced end of the cylinder and is formed with a port 33 which alternately registers 'ith the exhaust and inlet ports of the cylinder during rotation of the valve.

1 have shown, in Fig. l, the Water jacket for the cylinder located inside of the valve, and this construction 1 have reproduced as shown at 3i in Fig. 9,, and I also may dispose a Water jacket outside of the valve as shown at 35, if desired, to provide adequate cooling of the valve to compensate for the additional reciprocatory movement of the valve.

While I have described a specific emhodiment of my invention, 1. do not limit myself to the exact construction shown as there is a Wide range of modifications which may be resorted to Within the scope of the appended claims.

I claim:

l. in an internal combustion engine, a ported cylind '1', a ported valve member coaxial with the cylinder, means for rotating the valve member, a seat member therefor, means for reciprocating the valve member seat member, including a cam Way formed on one member and projection on the other member, operating in the cam Wa 2.

In an internal combustion engine, a cylinder having a ported end of reduced diameter, a revoluble ported valve member coaxial with the cylinder eutsideof said end, a seat member for the valve member, a continuous cam Way on oneof said members, and means on the other member operating in said cam rotation thereof;

5. In an internal combustion engine, a ported cylinder, a ported valve, said valve being Water jacketed inside. and outside, means for rotating the valve, and means for reciprocating the valve.

Signed at New, York, county of New York, State of New York, this 23rd day of February, 1916.
