UNITED STATES PATENT orin'on.
THOMAS E. SAWYER, OF CLOVERPOBT, KENTUCKY,
ADMISSION-VALVE.
Application filed March 22,
1 0 117K whom it may concern:
lie it known that I, THOMAS F. SAWYER, a citizen of the United States, residing at Lloveipui-t, in the county of Breckenridge and State of Kentucky, have invented certain new and useful Improvements in Admission-Valvcs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to valves for admitting oil. water, and gasolene, either separately or simultaneously, together with air, and in a heated condition, to the power cylinders of internal combustion engines; and it consists in the novel construction and combination of the parts h reinafter fully described and claimed.
In the drawings, Figure 1 is a vertical section through the inlet pipe of an internal combustion engine provided with admission valves according to this invention. Fig. 2 is a sectional plan view taken on the line 012- 0 in Fig. 1. v
A valve casing is provided, and.has a compound valve-seat 3 arranged in it. The air-inlet pipe of the engine is formed in two sections 4 and 5. The upper section 4 is secured to the casing 2 above the valve-seat, and the lower section 5 is secured to the casing below the valve-seat, and is arranged at a right-angle to the pipe section 4.
An air-valve 7 is provided and normally rests on the valve-seat 3 and closes the airinlet pipe. The air-valve 7 has a stem 8 which projects through a hole 9 in the bottom of the casing 2, and 10 is a spring connected with the projecting end portion of the valve stem and holding the valve on its seat. V
An annular chamber 12, for oil, such as kerosene, is formed around the upper part of the valve casing 2, and an annular chamber 14 for hot air or exhaust gas is formed around its lower .part. The chamber 14 is provided with an inlet-pipe 15 and an outlet-pipe 16, and is connected with the exhaust pipe of the engine.
The'oil chamber 12 is provided with an oil-inlet pipe 17. A regulating valve 18 for oil is provided, and is preferably a needle valve having its outlet and seat 19 at the middle part of the compound valve-seat 3. The needle valve 18 projects through a cross- Specification of Letters Patent. Patented June 23, 1914,

piece 20 in the hot oil chamber, and is provided with a hand wheel for operating it.
A second regulating valve 21 for gasolene is provided, and works in a crosspiece 22 in the aforesaid oil chamber. This valve 21 is also preferably a needle valve, and its outlet and seat 23 are arranged at the middle part of the compound valve seat 3,. A gasolene-inlet ipe 2 1 is provided and is connected to t 1e passage in the crosspiece around the needle valve 21.
. A third regulating valve 25 for water is provided, and works in a crosspiece 26 in the aforesaid oil chamber. This valve 25 is similar to the valve 21, and is provided with a water-inlet pipe 27 and a passage in the crosspiece, and its seat and outlet 28 are arranged at the middle part of the valveseat 3. The valve 7 closes all the openings at the middle part of its seat, and bears on the said seat above and below the said openings.
The oil is heated and vaporized, or is partially vaporized, in the oil chamber, and is admitted to mix with the air which is drawn-upwardly through the valve-seat 3 by the engine. ater or steam is admitted at will through the regulating valve 25 to mix with the oil and air While the engine is at work.
The gasolene valve 21 is used at starting the engine, when the oil. and water valves are closed, and the gasolene valve is closed after the engine has commenced working and is sufliciently heated to work with oil. The opening or lift of the valve 7 is controlled by the engine, and by its spring, the tension of which can be adjusted so as to give the best results.
The valve stem has a screwthreaded end portion 31, and a nut 32 is screwed on it so as'to adjust the tension of the spring 10.
The oil chamber is preferably spherical in form, and it is heated by the hot air chamber below it and from w ich it is separated by a partition 29.
What I claim is:
The combination, with a valve casing having a valve seat at its middle part and inlet pipe portions at its ends, said casing and one of the inlet pipe portions having jackets for oil and for hot air formed integrally with and arranged around them respectively and separated from each other by a partition, the oil jacket having integrally formed crosspieces at its middle part arranged let passages, and aninlet valve normally 10 around the valve seat, one of the said crossresting on the valve seat and closing the inpieces having an inlet passage for oil belet pipe portions and the inlet passages.
