VALVE MECHANISM FOR GAS-ENGINES.
Specification of Letters Patent.
Patented Mar. 27, 191?.
Application filed February 15, 1915, Serial No. 8,185. Renewed September 2, 1916. Serial No. 118,311.
To all whom it may concern:
Be it known that I, LELAND M. TURNER, a citizen of the United States, residing at Port Washington, county of Ozaukee, and State of Wisconsin, have invented new and useful Improvements in Valve Mechanism for Gas-Engines, of which the following is a specification.
My invention relates to improvements in mechanism for controlling the movements of the intake of a gas engine, and it pertains more especially, among other things, to the construction of the mechanism for ap plying an auxiliary closing pressure to such valve as the exhaust valve is opened by the positive action of a moving member of the engine the closed valve is more rigidly and securely held to its seat as the other valve is raised.
My invention is explained by reference to the accompanying drawing which represents a side view thereof in connection with a portion of the cylinder of an engine.
The several parts of my invention are referred to by reference numerals.
1 represents a portion of a cylinder of a gas engine of ordinary construction. 2 is an intake port. 3 is an exhaust port. The passage of gas through the intake port 2 is controlled by the valve 4, and the passage of gases through the exhaust port are controlled by the valve 5. The valve 4 is normally held to its seat by the spring 6, and said spring 6 is interposed between the cylinder head 7 and the collar 8. Thelcollar 8 is secured to the protruding end of the valve stem 9, and said spring is adapted by its recoil to normally retain said valve in its seat as stated.
The valve 5 is normally held to its seat by the spring 10, which spring is interposed between said cylinder ,head 7 and the collar 11. The collar 11 is secured to the protruding end of the valve stem 12 and said spring 10 is adapted by its recoil to normally retain said valve 5, as stated, to its seat.
It will, however, be understood that the exhaust valve 5 is opened for the escape of the products of combustion with the back stroke of the piston, and such valve is opened against the tension of said spring 10 by a movable member of the engine. Motion being communicated from such movable member of the engine to said valve 5, through the link 13, pivotal bolt 13, lever 14, adjustable bolt 15 and valve stem 12,
whereby with each alternate movement of the lever 11 said valve is raised.
ilxperience has, however, proven that as heretofore constructed there is a tendency for the intake valve 4 to vibrate in its seat while the other valve 5 is raised and one of the primary objects of this invention is to securely hold such valve 4'to its seat while the valve 5 is open. The lever 14 is pivotally supported from a bracket 15 on the pivotal bolt 16.
It will now be understood that as the end 17 of the lever 14 is raised in the act of raising the valve 5 the arm 18, which is rigidly fixed to said lever, is moved a slight distance toward the right, whereby motion is communicated from said arm to the arm 19 of the elbow crank lever 20 through the bolt 21, spring 22 and adjustable bolt 23. The arm 19 is formed integrally with the arm 23 and said elbow crank lever is pivotally supported from a stationary member 15 on a pivotal bolt 24. It therefore follows that as the arm 19 is thrown toward the right the free end of the arm 23 is moved downward and in contact with the flange 25 of the sleeve 8. As the sleeve 8 is thus pressed downward the valve 4, which is connected with said sleeve through the stem 2, is securely held in place in its seat 26, and it will, of course, be obvious that by a reverse movement of the lever 14 the valve 5 will be released from upward pressure and will be closed by the recoil of the spiral spring 10, as stated, while the valve 4 will be again released from the downward pull of the arm 23. In case the valve 4 is brought to its seat before the arm 18 has completed its movement toward the right,
- the spring 22 will yield sufficiently to permit of the further movement of said arm 18, as may be required by the oscillatory movement of said lever 14. i
The bolt 15 is adjustably secured in the end 17 of the lever 14, whereby it may be turned back in its threaded bearings as may be required to permit the valve 5 to become properly seated, and the bolt 23 is adjustably supported in the arm 19 and is adapted to be turned forwardly or backwardly as may be required to produce the proper adjustment of the arm 23 upon the collar 25 as the valve 4 is brought to its seat.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is 1. In a device of the described class, the the combination of intake and exhaust valves, means for normally retaining such valves in their closed position, a lever pivotally supported in close proximity to said valves, means connected. with one end of said lever for raising the exhaust valve of said engine, means for connecting the opposite end of said lever with a movable part of said engine, a third arm projecting laterally lrom the side of said lever, a bell crank lever pivotally supported in close proximity to said first named lever, means for connecting said third arm with one of the arms of said bell crank lever, and means-for connecting the opposite arm of said bell crank lever with said intake valve, whereby when said exhaust valve is held open said intake valve will be simultaneously held to its seat.
