Abstract
Abstract A device for piling and unpiling bulk material includes a frame having spaced-apart base portions and legs extending upwardly toward one another from said base portions, a feeder conveyor is mounted on the frame for piling material in the space spanned by the base portions. The device includes a scraper boom for removing piled material from the area spanned by the base portions. An additional conveyor may be provided for receiving material from the scraper boom and for supplying material to the feeder conveyor by means of a trolley.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
200 words
A device for piling and unpiling bulk material comprising; frame means having spaced-apart base portions adapted to be movably mounted on opposite sides of a storage area for bulk material, said frame means having leg means extending upward toward one another from said base portions and spanning said storage area, scraper boom means pivotally attached to said frame means for pivotal movement in a vertical plane for scraping bulk material from a storage pile located between said base portions and discharging such bulk material onto a conveyor extending in the direction of movement of said frame means, feeder conveyor means on said frame means for movement therewith along an area for storage of bulk material, said feeder conveyor means being independent of said scraper boom means and having a discharge means for feeding bulk material to the area spanned by said base portions from a conveyor which supplies bulk material from an area outside of the area spanned by said base portions, said feeder conveyor means being pivotally mounted on said frAme means for pivotal movement in a substantially vertical plane, and each of said scraper boom means and said feeder conveyor means being pivotally movable independently of one another.
Claim 2
Independent Claim
200 words
A device for piling and unpiling bulk material comprising; frame means having spaced-apart base portions adapted to be movably mounted on opposite sides of a storage area for bulk material, said frame means having leg means extending upward toward one another from said base portions and spanning said storage area, scraper boom means pivotally attached to said frame means for pivotal movement in a vertical plane for scraping bulk material from a storage pile located between said base portions and discharging such bulk material onto a conveyor extending in the direction of movement of said frame means, feeder conveyor means on said frame means for movement therewith along an area for storage of bulk material, said feeder conveyor means being independent of said scraper boom means and having a discharge means for feeding bulk material to the area spanned by said base portions from a conveyor which supplies bulk material from an area outside of the area spanned by said base portions, said feeder conveyor means being pivotally mounted on said frAme means for pivotal movement in a substantially vertical plane, and each of said scraper boom means and said feeder conveyor means being pivotally movable independently of one another.
Claim 3
Dependent Claim
45 words

Claim 4
Dependent Claim
39 words
The device of claim 2 and further including support means mounted on said frame means outside of the area spanned by said base portions of said frame means, said feeder conveyor means being pivotally mounted on said support means.
Claim 5
Dependent Claim
39 words
The device of claim 1, and further including support means mounted on said frame means outside of the area spanned by said base portions of said frame means, said feeder conveyor means being pivotally mounted on said support means.
Claim 6
Dependent Claim
38 words
The device of claim 4, wherein said feeder conveyor means is pivotally connected to said support means adjacent said base portions of said frame means and above the base of the storage area spanned by said base portions.
Claim 7
Dependent Claim
35 words
The device of claim 1, wherein said feeder conveyor means is pivotally connected to said frame means adjacent said base portions thereof and above the base of the storage area spanned by said base portions.
