DEFINITION

Classification: 123/90.43

(under subclass 90.41) Device wherein means is provided in the region of the pivot to vary the relationship of the rocker element to other elements of the operating mechanism in order to create, modify or eliminate clearance (lash) in the mechanism.

(1) Note. In most instances the lash adjusting means of a device of this subclass is of the self-operating kind; i.e., it functions on its own initiative in response to the presence of an incorrect amount of lash.
