Abstract
Abstract An apparatus for dividing a stream of particulate solids into a plurality of streams of particulate solids the apparatus comprising a belt conveyor having a leveler positioned above the belt surface to level the particulate solids on the belt surface so that the solids are discharged into a plurality of chutes to produce a plurality of streams each of which comprises a portion of the feedstream equal to a fraction defined by the width of the chute divided by the width of the belt conveyor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
229 words
An apparatus for dividing a feed stream of particulate solids into a plurality of streams of said particulate solids, each of said plurality of streams constituting a predetermined portion of said feed stream, said apparatus comprising; (a) a flat belt conveyor means adapted to convey particulate solids from a first end of said belt conveyor means toward a second end of said belt conveyor means; (b) a substantially vertical sidewall positioned on each side of said belt conveyor; (c) a leveler plate means pivotally positioned above said belt conveyor means to level said particulate solids on said belt conveyor means so that said particulate solids are of a uniform depth across the width of said belt conveyor, said leveler plate being of substantially the same width as said belt; (d) a feeder means for charging said particulate solids to said belt conveyor means between said first end of said belt conveyor means and said leveler plate means; (e) a receiver means for receiving said particulate solids from said second end of said belt conveyor means, said receiver means comprising a plurality of chutes for receiving said plurality of streams each of said streams constituting a predetermined portion of said feed stream, said predetermined portion being a fractional portion of said feed stream determined by the ratio of the width of each chute to the width of said belt conveyor.
Claim 2
Independent Claim
229 words
An apparatus for dividing a feed stream of particulate solids into a plurality of streams of said particulate solids, each of said plurality of streams constituting a predetermined portion of said feed stream, said apparatus comprising; (a) a flat belt conveyor means adapted to convey particulate solids from a first end of said belt conveyor means toward a second end of said belt conveyor means; (b) a substantially vertical sidewall positioned on each side of said belt conveyor; (c) a leveler plate means pivotally positioned above said belt conveyor means to level said particulate solids on said belt conveyor means so that said particulate solids are of a uniform depth across the width of said belt conveyor, said leveler plate being of substantially the same width as said belt; (d) a feeder means for charging said particulate solids to said belt conveyor means between said first end of said belt conveyor means and said leveler plate means; (e) a receiver means for receiving said particulate solids from said second end of said belt conveyor means, said receiver means comprising a plurality of chutes for receiving said plurality of streams each of said streams constituting a predetermined portion of said feed stream, said predetermined portion being a fractional portion of said feed stream determined by the ratio of the width of each chute to the width of said belt conveyor.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 wherein said leveler plate means comprises a relatively flat portion having a width to level said particulate solids across the width of said belt conveyor means and includes a plow positioned on its end nearest said first end of said belt conveyor to facilitate the leveling of said particulate solids.
Claim 4
Dependent Claim
29 words
The apparatus of claim 2 wherein said apparatus includes a leveler plate controller means adapted to adjust the height of said leveler plate means above said belt conveyor means.
Claim 5
Dependent Claim
14 words
The apparatus of claim 3 wherein said chute means are of the same size.
Claim 6
Dependent Claim
13 words
The apparatus of claim 3 wherein said chute means are of different sizes.
