HARVEY J'. SALLEE, OF WHITEHOUSE, CALIFORNIA,

INTERNAL-COMBUSTION ENGINE.

To all whom it may concern Be it known that I. HARVEY J. SAILEE, a citizen of the United States, and a resident of lVhitehouse, Shasta county, State of Calivide hollow water-jacketed valves through.

which the explosive mixture and the exhaust gases pass.

A further object of the invention is to provide an internal combustion engine valve construction which is simple in construction and which employs a fewer number of parts than has been heretofore employed. y

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description, where I shall outline in full that form of the invention which I have selected for illustration in the drawings action of a four-cylinder internal combustion engine, the inlet valve structure being shown in section. y

Fig. 3 is a cross section of the cylinder head taken on the line 3 3, Fig. 1.

Fig. 4 is a cross section of the cylinder head taken on the line 4 4, Fig. 1.

' Fig. 5 is a vertical, longitudinal section through the exhaust valve, taken on the line 5 5,.Fig. 3.

Fig. 6 is a cross section of the cylinder head showing a modified form of construction.

My invention is particularly adaptable for use in multi-cylinder engines and possesses many advantages over engines as at pres- Specication of Letters Patent.

ent constructed. The inlet valve consists of a single tube rotatable in time with the engine crank shaft and controlling the flow of the explosive mixture into all of the cylinders. Similarly, the exhaust valve consists of a single rotatable tube. The valve tubes arepreferably arranged in a removable cylinder head 2, which is provided with longitudinally disposed cylindrical seats 3 4 Ivalves 5 6 are arranged. The seats are preferably provided with bushings 7 which form `within which the rotary inletand exhaust bearings for the valves, but the bushings may be dispensed with when desired and the valves arranged to contact directly with the seats. The hollow valve seats are preferably arranged on opposite sides of the center line of the cylinders and are provided with ports which are connected t0 the cylin-- ders by the passages 8 9. The seats are spaced apart over the greater part of the external surfaces from the walls of the head 2, thereby forming a water jacket within the head, the water in which is in Contact with the exterior faces of the seats. The

seats are supported and attached to the head intermediate their ends by webs 12lwhich are preferably arranged between the cylinders.

lThe inlet valve tube 5, which seats in the seat 3, is connected to the engine crank shaft .so that, in a four-cycle engine, the valve rotates vat one-half the speed of the crank shaft, and the valve tube is provided with ports 13, positioned to register with the inlet passages 8 of the various cylinders, at the proper times during the operation of the engine. The exhaust valve tube 6 is similarly rotatable and is similarly provided with ports 14 which register at different times with the exhaust passage 9. The valve tubes are preferably connected to the crank shaft by means of a chain 15 meshing with a gear on the crank shaft and delivering its motion through sprockets to a chain 16, meshing with gears 17 on the valve tubes.

The inlet valve tube 5 serves as a manifold for delivering the explosive mixture to the conductor and extending into the valve twbe is a bell 24 which prevents the accumulation of condensed gasolene at the joint. The conductor 21 is connected to a passage 25 in the head 2 which opens into the seat 3. The valve tube 5 is provided at that part which lies at the opening of the passage 25 with a plurality of ports 26, so arranged that a clear opening from the passage 25 to the interior of the valve is always provided. .In this manner an equal supply of explosiveA mixture is always available for all of the cylinders.

The head is also provided with passages 27 connecting the exhaust valve seat 4 with the exhaust manifold 28, these passages bel ing arranged so that they are opened. by the ports 14 in therexhaust valve, to permit the gases of combustion to exhaust. The exhaust gases also discharge from the end of the valve, the exhaust manifold being connected thereto in the same manner as the conductor 22 is connected to the inlet valve. The various gas passages within the head are thoroughly water-jacketed, so that the exhaust gases are cooled before they discharge into the exhaust manifold and a portion of this heat is taken up by the incoming explosive gas. The exhaust gases are further cooled by the passage of air through the pipe 31 which extends through the exhaust valve.

Means are also` provided for lubricating the valves in their seats, since i't is evident that the valves must have rather tight fits in the seats to prevent leakage. The lubricating oil .will also assist in preventing leakage. Extending longitudinally of the head 2,'a'nd preferably directly above the valve seats, are thickened portions 32, through which are drilled holes 33 which serve as oil passages, and below the seats are similar thickened portions 34 provided with oil passages 35. With the valves removed, holes 36 are drilled down through the webs 12,

connecting the upper and lower oil passages 33 and 35. The thickened portions 32. and 34 are spaced from the seats as far as is convenient in order to provide for water circulation about as large an area of the seats as possi'ble. The valves are provided on their outer surfaces with oil grooves 37 which register with the oil holes 36 and which dis# tribute the oil over the surfaces of the valves. Oil is forced through the pipe 38 into the upper passages 33, whence it Hows to the valves and thence into the passages 35, which are connected to the oil sump by the pipe 39.

The spark plugs 41 are set in wells 42 formed in the head directly over the cylinders and between the valve seats.

In Fig. 6, I have shown a modified construction in which the rotary valve tubes are supported interiorly |by stationary tubes 43 and 44, which are provided with ports which register with the various inlet and outlet ports in the valve seats.

I claim:

1. In an internal combustion engine, a plurality of cylinders, a cylindrical Valve seat arranged adjacent. said cylinders, passages connecting said cylinders with said seat, a hollow rotary valve comprising a manifold arranged in said seat and provided with ports through the lateral wall thereof,

said ports adapted to place said rotary manifold in communica-tion with said passages, a carbureter, a conductor connecting the carbu-reter with -one end of said rotary manifold and a conductor connectin the carbureter with said rotary manifold lntermediate its ends.

2. In an internal com'bustion engine, a plurality of cylinders, a c lindrical valve seat arranged adjacent sai cylinders, passages connecting said cylinders with said seat, a rotary valve bearing in' said seat and provided with ports adapted to register with said passages, an oil channel arranged above said seat, a second-oil channel arrangedgbelow said seat and passages for conducting oil from said first channel to said seatand from said seat to said second channel.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 8th day of February, 1917.
