Abstract:
1. A single lever control for manually manipulating a movable stem of a hydraulic valve spool commonly associated with a directional control valve, said lever control comprising, in combination: a handle assembly having an elongate shaft with first and second ends and an outer casing having upper and lower ends and an inner cylindrical bore for slidably accepting therein said elongate shaft, said upper end having means for supporting a biasing element effective for biasing said outer casing relatively about said elongate shaft; a mounting assembly having a vertical support member integrally connected to an adapter plate configurably arranged to fit about and over a select mountable portion of the directional control valve, said adapter plate having a large aperture extending therethrough to permit passage of the moveable stem, said vertical support member having a lever pin fixedly attached thereto and extending perpendicularly outward therefrom; a pivot block having an upper planar member integrally comprising an upward-positioned socket for accepting therein and fixedly attaching said second end of elongate shaft, forward and rearward faces, and left and right sideward members, said forward face having a valve-actuating stem extending outwardly therefrom a predetermined distance to engage and interact with the movable stem extending through said large aperture, said pivot block having a bore generally extending parallel to said forward and rearward faces for slidably accepting therein said lever pin; means for locking and securing said handle assembly relatively to said mounting assembly to prevent said valve-actuating stem from movably interacting with the movable stem; and means for linking said lower end of outer casing with said locking and securing means to effectuate coordinating movement of each while biasing forces act on said biasing element.
