Abstract
Abstract The apparatus is a live bottom for a stockpile, comprising an aligned series of hoppers which are rectangular in plan and are open at the top to receive the base of a stockpile. Each of the aligned hoppers has a bottom discharge opening in the form of a slot extending substantially continuously across the hopper, and has a bottom portion that extends substantially throughout the length of the slot, along at least one side of tee slot, and slopes downward toward the slot. Mechanism is provided for vibrating the hopper to cause material to flow across the downward sloping portion of the hopper into the slot. A conveyor extends below the slot throughout the length of the slot, for receiving material discharged through the slot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A live bottom for a stockpile, comprising an aligned series of hoppers which are rectangular in plan and are open at the top to receive the base of a stockpile, and which have aligned discharge openings consisting of a slot in the bottom of each hopper extending substantially continuously across the hopper, each hopper having a bottom portion that extends substantially throughout the length of the slot, along at least one side of the slot, and slopes downward toward the slot, and mechanism for vibrating each hopper to cause material to flow across the downward sloping portion of the hopper into the slot.
Claim 2
Dependent Claim
103 words
A live bottom for a stockpile, comprising an aligned series of hoppers which are rectangular in plan and are open at the top to receive the base of a stockpile, and which have aligned discharge openings consisting of a slot in the bottom of each hopper extending substantially continuously across the hopper, each hopper having a bottom portion that extends substantially throughout the length of the slot, along at least one side of the slot, and slopes downward toward the slot, and mechanism for vibrating each hopper to cause material to flow across the downward sloping portion of the hopper into the slot.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1, wherein each hopper has two generally flat portions extending substantially throughout the length of the slot, along the two sides of the slot, and sloping downward toward the slot.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 2 wherein each hopper has a baffle extending upward from the slot and generally parallel to the slot.
Claim 5
Dependent Claim
19 words
Apparatus according to claim 3 wherein the baffle, in transverse section, is in the shape of an inverted V.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 1 wherein each hopper is mounted for horizontal vibratory movement transverse to the slot.
Claim 7
Dependent Claim
41 words
Apparatus according to claim 5 wherein the mechanism for vibrating each hopper comprises a pair of eccentrically loaded parallel shafts, rotating in opposite directions, the axes of which lie in a plane which is generally vertical and parallel to the slot.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 1 comprising a common belt conveyor extending below the slots, for receiving material discharged through all of the slots.
Claim 9
Dependent Claim
77 words
Apparatus according to claim 7 comprising a plurality of series of similar hoppers, the bottom discharge slots of each series of hoppers being substantially aligned and parallel to the slots of each other series, and each series of hoppers having a common belt conveyor extending below the slots; and a collecting belt conveyor arranged to receive material from the ends of the other belt conveyors; the hoppers being closely juxtaposed to form the base of a stockpile.
