VALVE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Original application led January 17, 1913,`Seria1 No. 742,720. Divided and this application-filed May 27,

1915. Seria1`No. 30,852.

To all whom it may concern.'

Be it known that FRANCIS M. Rrrns, de?

ceased, late a citizen of the United States, residing at Ithaca and Slaterville Springs, New York, in the county of Tompkins and State of New York, did invent certain new and useful Improvements in Valves for Internal-Combustion Engines, (described in his previous application, Serial No. 742,720, filed January 17., 1913, of which this is a division,) of which the following is a specification.

Tle object of this invention is to produce a simplified form of valve mechanism for an internal combustion engine.

Another object of the invention is to provide an improved device by whichthe combustion in an internal combustion engine is secured.

These and other objects of the invention will be fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

This application is a division of prior vapplication No. 742,720, on which Patent 1,178,181 was issued April 4, 1916,.to which reference is made for a more complete disclosure.

In the accompanying drawings, Figure 1 shows a vertical section through the valve mechanism, the section being taken on the line 1"-1x of Fig. 2. Fig. 2 is' a verticalr section through .the valve mechanism, the` section being taken on the line 2"-2 of Fig. 1. Fig. 3 is a vertical section takenl through the baffle plate and cylinder head, the section being taken on the line 3L-3" of Fig. 2. Fig. 4 is a. horizontal section through the valve chamber, the section being taken on the line 4* X of Fig. 2.

In the accompanying drawings like reference numerals indicate like parts. y

In the drawings reference numeral 1 indicates a cylinder f an engine on which is fastened acylinder head 2. In this cylinder head is a. valve chamber at the bottom of which is located 'a baiile plate 3 having an opening 4 extending therethrough. A nozzle 5 is placed at one end of this opening having an air supply tube 6 and an oil supply tube 7 communicating therewith. The air supply tube 6 connects with the tube 8 through .which air under pressure is: frnished to the valve chamber for use inthe engine. Through the nozzle 5 a mixture of 55 oil and air is blown through the tube 4 and is burned therein for the purpose of heats, ing the baffle plate through which the opening goes. The opening 4 is enlarged .at 20 `for the purpose of increasing the combustion space and to reduce the thickness of into the outer air. Centrally on this baffle plate is formed a valve seat 9. Concentric with the seat 9 a flange 10 is formed in the valve-chamber and on this flange is formedJO a valve seat 11, the seat 11 being concentric with the seat 9. The seats 9 and 11 may be referred to as two concentric ta ering sury faces of a single valve seat. (l)

which has a central opening 13 therein with which opening communicates the oil supply tube 14, the valve being formed with an up- `wardly extending tube 15 which surrounds the stationary tube 14 and makes a. tight 80 sliding connection therewith. The tube 14 is stationary and vthe valve 12 is free -to rise and fall so as to control the feed of oil from the tube 14 to the baffle 3.

For the purpose'of lifting the valve a 85 rocker arm 16 is provided, pivoted at 17 and operated by a link 18, which link is driven from'a rock shaft of the engine in the usual manner.

As the valve 12 rises it lifts from both the 90 seat 9 and the seat 11. Oil is admitted past the seat 9 and compressed air is admitted past the seat 11. The air and oil come' into contact with each other and into contact with the baffle plate 3 which is maintained 95 at an igniting temperature, first by the torch or nozzle 5 and afterward as a result of the combustion. This causes the oil to burn with the air which burning is continued through a' definite interval of time 100 rather than during merely an instant which would characterize an explosion as ordinarily occurs in a -combustion engine which the charge is mixed and compressed Patented Feb. 6, 1917.

operating with the valve seats 9 and ll'is a valve 12 75 before ii is ignited. while iii this engine,

with which this valve mechanism will beused, the combustion will begin as soon as the valve lifts to admit the air and oil to the baffle plate and will continue until the valve closes again. The valve will not lift `until the forward stroke of the piston is labout to. begin and the valve will remain open for a considerable fraction of the piston stroke. That is, through one sixth or a l third or even one half or more of the 180 iinto the engine cylinder,

pif further combustion. the piston of the engine is pressed down and of the piston stroke.

To lsecure theadmission of oil past the valve seat 9 the `oil in the tube 14 is kept under suiiicient pressure to cause the oil to feed against the resistance of the compressed air which is fed past the valve seat 11. As the compressed air and oil burn the volume of it increases. does not increase. If it did the air would ybe pushed back through the tube 8, cutting Instead, however,

the products of combustion advance from the baffle through the openings 21 and as they advance from the baffle they expand causing the engine to generate power. As they advance they make room for the air and oil that passes the valve 12 to support the combustion -which continues as long as the valve remains open. To insure 'proper feed the parts will be proportioned so that the pressure in the enginev cylinder is slightly less than the pressure'in the air pipe 8;.
