Unloading auger position switch
First Claim
1. A self-propelled agricultural combine for harvesting a crop from a field, and processing the crop to separate grain from straw and chaff, the combine comprising:
- a chassis;
a propulsion means mounted on the chassis;
ground engaging means for supporting the chassis from the ground and propelling the chassis across a field when the ground engaging means is rotated by the propulsion means;
harvesting means extending outwardly from the chassis for harvesting a crop from a field;
threshing and separating means located in the chassis for separating grain from straw and chaff of the harvested crop;
a clean grain compartment mounted on the chassis, the clean grain compartment receives the grain separated from the straw and chaff by the threshing and separating means;
an unloading tube pivotally mounted to the chassis so that the unloading tube can pivot about a pivot axis defined by a pivot pin fixedly mounted to the unloading tube, the unloading tube can be pivoted from a substantially longitudinally aligned storage position with the chassis, to an unloading position where it extends outwardly from the combine for loading clean grain into a receiving truck;
positioning means for positioning the unloading tube from the storage position to the unloading position, and conversely from the unloading position to the storage position;
a conveying means is used to remove grain from the clean grain compartment and direct it to the unloading tube; and
an unloader positioning control switch for controlling the positioning means of the unloading tube, the control switch is fixedly mounted to the chassis substantially axially with the pivot axis and is provided with a means for detecting the position of the unloading tube and in response to detecting the unloading tube in either the storage or unloading position the control switch deactivates the positioning means, the means for detecting the position of the unloader tube comprises a key depending from the control switch which engages a slot formed in the pivot pin.

Abstract
An unloader position control switch assembly is positioned along the pivot axis of an unloader tube and is provided with a downwardly depending key that engages a slot formed in a pivot pin fixedly secured to the unloader tube. The switch assembly has two switch elements that are mechanically interconnected and are automatically resettable after the unloading tube substantially reaches either the storage position or the unloading position for the unloading tube. An operator'"'"'s switch is interconnected with the control switch assembly so that an operator may easily manipulate the positioning of the unloader tube.
