Title: Valve operating gear for internal combustion engines
IPC: F01L1/12
Filed: 1922-11-11
Abstract: 209,541. Green, G. Nov. 11, 1922. Valve gear.-In valve gear of the type in which teeth upon the valve lever engage teeth upon the valve stem, lateral pressure exerted by the teeth on the valve stem is taken up by a roller bearing against the valve stem, or is avoided by arranging the pitch line of the teeth so that the resultant pressure acts along the axis of the valva stem. Fig. 1 shows a valve stem 9 formed with teeth 8 engaging teeth 7 on a camactuated lever 5, lateral pressure being taken up bv a roller 11 mounted on the lever and bearing against a curved surface 10 on the valve stem. Fig. 3 shows the valve stem formed with teeth 16 at each side engaging corresponding sets of teeth 18 on a lever 17, so that the resultant pressure acts along the axis of the valve stem. In modifications, the valve lever may engage a grooved or positive cam; the roller may be carried by a fixed part as shown at 20, Fig. 6; the lever 5, instead of being formed with teeth, may carry a roller 22 engaging a single tooth surface 21 on the valve stem; or teeth formed on the cam shaft may directly engage teeth on the stem.

A buckle for a safety belt comprises a hook 12 which is engageable with a stationary yoke member F and a pawl 15 spring biased to close the opening in the hook and manually operable by a pivoted ejector 16 which both opens the hook and, by engaging surface 18 with the yoke member, disengages the hook from the yoke member. The pawl is movable to open the hook by mounting the yoke member on the hook. The hook is formed in a plate 10 which is mounted between two cap pieces by pins 13. The plate has a slot with a spring 28 to provide a friction grip on a belt. The ejector with a handle 17 pivots on a pin 13.
