Abstract
Abstract A uni-lever system for controlling operation of multiple functions. A uni-lever is coupled to linkage for actuating the multiple functions and supported for pivotal movement through a spherical bearing permitting controlled movement in predetermined planes effecting corresponding movement of the actuating linkage. Auxiliary equipment being controlled is coupled through the linkage connected to the uni-lever to respond only to movement of the uni-lever in a particular plane. Movement in the remaining planes is restricted due to the spherical joint and stabilizing linkage.
