Abstract
A control linkage for varying the length of stroke of a hydraulic cylinder is disclosed wherein a slide member is telescopically received within a bracket member, one of these members being connected to the extension end of the hydraulic cylinder while the other member is connected to the base end. A limiting mechanism in the form of a series of holes in one of the members alignable with a slotted opening in the other member and a fastener positionable within one of said holes and also through the slotted opening serves to limit the amount of telescopic movement of the slide member from the bracket member. As a result, the extension of the hydraulic cylinder can be selectively varied according to the preset length of the control linkage. An alternative embodiment in which a fastener is positionable within the holes externally of the slotted opening provides a two way stroke limiter by restricting the length of the retraction stroke of the hydraulic cylinder.
