Abstract

128,981. Thomas, G. H., Havilland, G. de, and Morgan, H. R. Sept. 8, 1917. Valve-gear.-To prevent a beat or lift valve from closing violently upon its seat, the valve mechanism is returned to its inoperative position by a spring which supplements the closing-spring of the valve. As shown in Fig. 1, a light spring 17 closes the valve, and a spring 18 returns the actuating-mechanism. The spring 18 bears upon a member 21 which is free to slide, with lost -motion, upon the stem of the valve. Recesses may be provided in the head 25 for the insertion of a gauge between the head and the valve-stem.
