Abstract: Lower spiked rollers in the bottom of a cotton accumulator are inclined in the downstream direction towards an opening and rotate in the same direction to pull cotton down to the opening. An upper spiked roller located above the opening and above the last of the lower spiked rollers is only partially exposed to the cotton in the accumulator. The upper roller meters the cotton and tears apart clumps. An opening above the upper roller defines an upper discharge opening over the main discharge opening. When in a non-rotating condition, the spiked rollers act as a floor for the accumulator and prevent egress of the cotton through the openings.

Abstract: A hood receives a stream of material including a mix of cotton, air and debris from an air delivery system on a cotton harvester. A forward deflector directs the mixture towards the rear of an accumulator. The deflected mixture passes under finger grates which retains cotton but allows some of the air and light trash to pass through out of the stream. A curved rear deflector forces the remaining mix downwardly towards the accumulator and prevents build-up on receptacle walls. Air and light debris change direction abruptly at the bottom of the rear deflector and exit through an inlet area and upwardly directed path at the back of the deflector. The momentum of the heavier cotton prevents cotton from making the tight turn around the bottom of the deflector and directs the cotton towards the receptacle or accumulator. The inlet area can be adjusted or closed completely to prevent cotton loss in certain conditions.

Abstract: A stabilizer system provides leveling for a towed harvester vehicle. The harvester includes a hitch having a gimbal mounting to the tractor. The subframe is utilized to accommodate the gimbal and provides for utilizing the mass of the tractor to react to the stabilizer system leveling forces.

The telescoping assemblies retract and extend to varied positions and provide correction. Flow to extend and retract the telescoping assemblies is provided through a proportional pendulum type valve that increases flow as needed when tilted from horizontal. The flow is increased and decreased in proportion to the amount of tilting from the home vertical position.

Abstract: A refrigerant system is operable in either heating mode or cooling mode. The system is also provided with an economizer cycle that will function in either heating mode or cooling mode. A four-way valve assembly selectively communicates refrigerant from either an indoor heat exchanger or outdoor heat exchanger to an economizer heat exchanger. The valve assembly further includes a restriction for restricting a refrigerant flow downstream of the economizer heat exchanger. The valve assembly provides two distinct restrictions such that a different size restriction is presented to the flow in cooling and heating modes. In this way, a single valve assembly can provide both the required routing for the alternative heating and cooling modes, and at the same time allow for distinct restriction sizes for the two modes without the necessity of separate expansion devices, also improving overall system cost and reliability.
