Abstract: In a single lever control for the feeder conveyors of a combine harvester, movement of a manually operated lever directly actuates a drive train for driving the conveyors in a forward or normal operating direction. A second lever controls actuation of a drive train for driving the feeder conveyors in a reverse direction. Movement of the second lever is responsive only to movement of the first through a cam slot and cam follower arranged so that selection of the drive for one direction automatically disengages the drive for the opposite direction. A detent gate at the neutral position forces the operator to pause when passing through the neutral position, that is when disengaging one drive and engaging the other.

Abstract: A ratchet system includes a "T" shaped stop-engaging member mounted in a plane perpendicular to a rotating spindle and parallel to a circular carrier member having stop members mounted on the periphrey and rotating with the spindle. The stem of the "T" member is rotatable mounted in a housing surrounding the spindle and upon selective rotation, the ends of the "T" member cross-bar engage the stop members to prevent rotation in a selected direction. The "T" cross-bar transmits the engagement force directly to a recess in the inner wall of the housing. A hand-actuated knob assembly located outside the housing is connected to the "T" member stem by a resilient bushing which provides a restoring force to return the "T" member to a stop engagement position following defection by stop members traveling in a direction counter to that intended to be prohibited.

Abstract: The gear shift mechanism of a manually operated transmission having multiple forward speed ratios and a reverse drive ratio includes a gear selector shaft under the manual control of the vehicle operator. A selector pin fixed to the selector shaft moves within a system of interconnected slots in a guide plate mounted on the transmission casing. Movement of the gear selector lever causes the selector pin to move within the restricted path defined by the slots. A pawl supported on the surface of the guide plate is mounted pivotably in a slotted hole that permits linear displacement with respect to the pivot pin. A torsion spring continuously applies a resilient force to the pawl tending to restore the pawl to a normal position, where it prevents movement of the selector mechanism from a forward drive position directly to the reverse drive position.

Abstract: A transmission shifting apparatus for controlling the speed and direction of movement of a vehicle. The transmission shifting apparatus utilizes an operating shift lever movable in a first direction through a plurality of successive positions in each of which it controls the forward movement of the vehicle at a predetermined speed, and a second opposed direction through a plurality of successive positions in each of which it controls the reverse travel of the vehicle at predetermined speeds. The shift lever is movable in a transverse direction between the first and second paths of movement to define a neutral or idle position in which no motion is imparted to the vehicle through the transmission. Movement of the transmission shift lever through the neutral position effects engagement of limit stops to retain the shift lever in the idle or neutral position.

Abstract: A snubber (12) includes a fixed member (14) and a movable member (16). A variable volume chamber (20) is defined between these two members (14, 16). The chamber (20) includes an orifice (22). A body of extrusible material (26) substantially fills the chamber (20). A rotary actuator (6) carries a lug (28) that contacts the movable member (16) when the actuator (6) moves beyond a predetermined position. This contact pushes the movable member (16) against the extrusible material (26) to decrease the volume of the chamber (20) and to cause the extrusible material (26) to be extruded through the orifice (22). This stops the rotation of the actuator (6) and absorbs its kinetic energy. The snubber (12) is supported by a frame member (10). Preferably, the frame member (10) has a cavity (40) into which material extruded through the orifice (22) is received.
