ABSTRACT:
An improved mechanism is provided for selectively altering the positioning of an inwardly depressable, outwardly biased, shiftable structure, such as a splined shaft, and for releasably holding such structure in either of an inwardly depressed or an outwardly shifted position thereof. The mechanism is especially adapted for use with powered wheel, hub assemblies, such as commonly employed in combines or other normally self-propelled agricultural implements or the like, in which provision is to be made for disengaging the hub from an associated power shaft to permit towing of the implement at higher speeds than normal for field running thereof. In the mentioned application, the mechanism provided by the invention is utilized in lieu of the bolt mounted, reversible, disengaging plate heretofore conventionally employed in the hub assemblies of such agricultural implements and facilitates manual control over engagement and disengagement between the hub and the associated power shaft without the necessity for unbolting, reversing and remounting a reversible disengagement plate, as has been typically required in prior constructions.
