KELLY COCK ROTARY DRIVE MECHANISM ABSTRACT A valve body forms flow passages at longitudinally opposite sides of a stopper to be brought into communication through the stopper when the stopper is rotated from closed to open positions, the body having a side opening. To rotate the stopper there are provided: a) a sleeve adapted for reception in the side opening, the sleeve having retainer structure to interfit shoulder structure on the body for block- ing rotation of the sleeve in the side opening, b) a crank received in the sleeve for rotation therein, thereby to rotate the valve stopper, and c) interengageable stop shoulder structure on the crank and sleeve to limit rotation of the crank and the stopper at stopper open and closed positions. The retainer structure typically includes two tangs projecting in spaced apart relation for reception in grooving in the body.
