Abstract
A vehicle control mechanism for manipulating three controllable members through one control handle. The control mechanism includes a support rigidly attached to the vehicle. The support rotatably carries three control assemblies which are operably connected to one of each of the three controllable members. The control mechanism also includes a drive assembly rotatably carried by the first and third control assemblies first, second and third control assemblies and the support have force selectively transmitted therebetween by a roller which is contained in the control assembly by roller retainers of the support. The force which manipulates the controllable members is derived from the operator selectively pivoting the handle about the third control assembly. To manipulate the various control assemblies the operator will either pivot the handle to engage the handle and the dive assembly or pivot the handle to engage the handle and the second control assembly. The controlling force is supplied to the respective control members by the operators rotation of the handle about its rotational connection to the third control assembly; after the handle has been selectively pivoted about its pivot point. The final features of the control mechanism are a centering spring which urges the handle into a normal position about its pivot point, which normal position cooperates with a regulator that produces selective engagement of the individual controllable members by sequential pivoting and rotation of the handle.
