Abstract
Abstract Apparatus for weighing-out material from a collapsible surge bin. The surge bin is mounted above a collapsible frame such that the points of attachment of the surge bin to the collapsible frame comprise a load cell for weighing the surge bin and the contents thereof. The load cells are connected to control circuitry which actuate a gate in the bottom of the surge bin to thereby dispense asphalt-aggregate material from the surge bin. The control circuitry also operates a door in a batcher above the surge bin to thereby regulate the flow of asphalt-aggregate material being delivered into the surge bin.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
200 words
A method of weighing and dispensing material from a surge bin comprising the steps of: collecting said material in a batcher to a predetermined amount; dispensing said collected material from said batcher into said surge bin; dispensing a quantity of material from said surge bin while again collecting material in said batcher to said predetermined amount; continuously weighing said surge bin and material therein as said material is dispensed from said surge bin to determine an initial weight of material dispensed from said surge bin; interrupting dispensing of said material from said surge bin responsive to said predetermined amount of material being collected in said batcher; storing said initial weight of material dispensed from said surge bin prior interruption of dispensing of said material from said surge bin; dispensing said predetermined amount of collected material from said batcher into said surge bin; weighing said surge bin and material therein to establish the weight of said surge bin and material therein; dispensing a quantity of said material from said surge bin; and continuously weighing said surge bin and material therein while material is being dispensed from said surge bin to determine a further weight of material dispensed from said surge bin.
Claim 2
Independent Claim
200 words
A method of weighing and dispensing material from a surge bin comprising the steps of: collecting said material in a batcher to a predetermined amount; dispensing said collected material from said batcher into said surge bin; dispensing a quantity of material from said surge bin while again collecting material in said batcher to said predetermined amount; continuously weighing said surge bin and material therein as said material is dispensed from said surge bin to determine an initial weight of material dispensed from said surge bin; interrupting dispensing of said material from said surge bin responsive to said predetermined amount of material being collected in said batcher; storing said initial weight of material dispensed from said surge bin prior interruption of dispensing of said material from said surge bin; dispensing said predetermined amount of collected material from said batcher into said surge bin; weighing said surge bin and material therein to establish the weight of said surge bin and material therein; dispensing a quantity of said material from said surge bin; and continuously weighing said surge bin and material therein while material is being dispensed from said surge bin to determine a further weight of material dispensed from said surge bin.
Claim 3
Dependent Claim
132 words
The method of claim 1, further comprising the steps of: responsive to said material being completely dispensed from said surge bin prior to said batcher collecting said predetermined amount, terminating dispensing of material from said surge bin by closing a dispensing opening in said surge bin through which said material is dispensed; storing the weight of material dispensed from said surge bin; responsive to said batcher collecting said predetermined amount of said material, dispensing said collected material from said batcher into said surge bin; weighing said surge bin and the material therein to establish the weight of said bin and said material; dispensing a quantity of material from said surge bin; and continuously weighing said surge bin and material therein to determine a further weight of material dispensed from said surge bin.
