Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A closed, longitudinally-tapered container of the type adapted to accommodate a compacted load introduced into the container at the larger end thereof and to discharge the load through a discharge opening at said larger end of the container, load ejection means for providing an initial impetus to the compacted load for moving it through the container discharge opening, said ejection means comprising a plate disposed across the container interior adjacent to but spaced from the narrow end of the container, said plate being supported solely by hinges along its upper margin and resilient means interposed between the adjacent end of the container and said plate for storing energy as said plate is pivotally moved toward said adjacent container end as the load is compacted in the container and for discharging said stored energy through said plate to the load to provide said initial impetus to the load as it is discharged from the container.
Claim 2
Dependent Claim
154 words
A closed, longitudinally-tapered container of the type adapted to accommodate a compacted load introduced into the container at the larger end thereof and to discharge the load through a discharge opening at said larger end of the container, load ejection means for providing an initial impetus to the compacted load for moving it through the container discharge opening, said ejection means comprising a plate disposed across the container interior adjacent to but spaced from the narrow end of the container, said plate being supported solely by hinges along its upper margin and resilient means interposed between the adjacent end of the container and said plate for storing energy as said plate is pivotally moved toward said adjacent container end as the load is compacted in the container and for discharging said stored energy through said plate to the load to provide said initial impetus to the load as it is discharged from the container.
Claim 3
Dependent Claim
81 words
A container as claimed in claim 1 in which said plate has a length less than the height of the container interior so that the lower margin of said plate is spaced from the floor of said container, and an inclined deflector plate extending from the container floor to the adjacent narrow end of the container and passing closely beneath the free end of said plate for directiNg the load upwardly against said plate as it is compacted into the container.
Claim 4
Dependent Claim
53 words
A container as claimed in claim 1 in which said resilient means comprises a series of spaced compression springs, members rigidly secured to the rear face of said plate for freely accommodating the end portions of said springs, the opposite ends of said springs bottoming against the adjacent narrow end of the container.
