Abstract: A self-propelled harvester or combine is provided with a bifolding panel structure at the lateral side thereof on which a bin unloader tube is swingable from an outwardly extending unloading position to a transport position alongside the panel structure. When the unloader tube is in its transport position, the lower part of the panel structure can be pivoted about its pivot connection with the upper part of the panel structure between closed and open positions, but the unloading tube in its transport position prevents opening the upper part of the panel structure. When the unloader tube is raised, the upper part can be moved from its closed to its open position.A linear air spring or actuator biasingly maintains the lower part of the panel structure in whichever of its open and closed positions it is placed, and when the upper part is swung to its open position, it is maintained in that position by the linear actuator.

Abstract: An electrohydraulic control system for a pair of hydraulically actuated vehicle transmission clutches operable to effect high and low speed ranges. High and low hydraulic clutch valves are pilot operated by a solenoid valve which delivers pressurized fluid to pressure chambers associated with the flow control elements of the clutch valves. The solenoid valve is controlled by a circuit which includes a relay operated switch, a manually operated switch controlling the relay operated switch and a clutch pedal operated switch in series with the manually operated switch. The relay operated switch opens when the clutch pedal is operated thereby causing the transmission to be in a low speed condition when inching the vehicle.
Abstract: A single manually operated control lever is operable to operate a range shift mechanism and a park lock mechanism in a vehicle transmission. The control lever is pivoted to a pivot bracket on a first horizontal axis and the pivot bracket is pivoted to a stationary console on a second horizontal axis lying in a plane normal to the first axis. The control lever selectively and alternatively engages notches in a pair of operating members connected to the range shift and park lock mechanisms. A spring interacting between the pivot bracket and the control lever biases the latter into engagement with the notch on the range shift operating member.

Abstract: A lift truck hydraulic control system designed to conserve energy includes a pair of separately controlled pumps (21, 22). One pump (21) supplies pressure fluid to a valve (12) for a steering cylinder (11) by way of a high priority port (34) of a priority valve (32) with the low priority flow passing to parallel connected lift and tilt valves (19, 18) which control operation of the lift cylinder (15) and tilt cylinders (16, 17), respectively. The capacity of pump (21) is sufficient to provide proper, effective operation of the steering and tilt functions but is not adequate to provide hydraulic fluid flow for high speed expansion of the lift cylinder (15). The other pump (22) is operated to supply additional pressure fluid flow for high speed lift only when the lift valve (19) is shifted to a raise position. In one embodiment, a low speed lift is obtained by using the output of the pump (21) and a high speed lift is obtained by selectively adding the output of the second pump 22.
