Abstract
The capacity of a harvester grain bin (12 or 120) is increased by foldable extensions (37, 38, 39, 41 or 101, 102, 103, 107) pivoted to the upper lips (27, 28, 29, 31 or 113, 114, 128, 129) by hinges (46, 47, 51, 52 or 111, 112, 130, 135) which permit the extensions to be raised from lowered positions to raised positions in which they are secured by corner pins (81, 82, 83, 84 or 104, 106, 108, 109).
Claims7
A harvester grain bin having
- a front wall,
- a rear wall,
- a pair of laterally opposite side walls interconnecting said front and rear walls, the upper ends of said walls each presenting a rim of predetermined horizontal width, said rims being substantially coplanar and defining an upwardly facing quadrilateral opening,
- front and rear upright extensions pivotally connected at their lower inboard edges on transverse horizontal axes to the inboard edges of said front and rear walls, respectively, said front and rear extensions being pivotable from extended upright positions downwardly and inwardly to at least to a generally horizontal position,
- laterally opposite side extensions having their lower outboard edges pivotally connected on longitudinal axes to outboard edges of said rims of said laterally opposite side walls, respectively, said side extensions being pivotable from extended upright positions downwardly to positions alongside the laterally outer sides of said side walls, and
- releasable fastening means interconnecting adjacent ends of said extensions at the four corners formed by the extensions in their extended upright positions.

A harvester grain bin having
- a front wall,
- a rear wall,
- a pair of laterally spaced side walls interconnected at their opposite longitudinal ends to laterally opposite ends of said front and rear walls, said walls each presenting a rim of predetermined width at its upper end, said rims being substantially coplanar and defining an upward facing opening in said bin,
- front and rear bin extension panels pivotally connected at their lower inboard edge to the inboard edge of said rims on said front and rear walls, respectively, said front and rear bin extension panels being of less transverse width than the distances between the rims on said side walls at the front and rear of said bin opening thereby permitting said front and rear bin extension panels to pivot from an upright bin extension position downwardly through said opening to a lowered position within said grain bin,
- a pair of laterally opposite side extension panels having their lower outboard edges pivotally connected to the outboard edges of said rims on said side walls, respectively, for pivotal movement about generally longitudinal axes between a generally upright bin extension position and a lowered position at the laterally outer sides of and alongside said side walls, and
- releasable fastening means securing said extension panels in their upright bin extension positions.
