Abstract
Abstract Method for more uniformly blending a layered stack of bricks having a central core section of lesser hardness and lighter color than in a surrounding outer shell section. The bricks are first unloaded from a hack into layers which include a corresponding core section and surrounding shell section. Thereafter, the bricks in each alternate layer are rearranged by placing bricks from the normally occurring core section areas into the normally occurring shell section areas and vice versa. Then the layers of bricks (both rearranged and unaltered) are restacked. The resulting stack will be blended such that when each "slice" of the stack is strapped into a packaged group of bricks, the resulting packaged groups will have approximately equal numbers of bricks having differing degrees of hardness and color.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A method for blending a stack of bricks comprising a plurality of vertically superimposed layers, each layer comprising a plurality of bricks, said stack having a central core section of lesser hardness and lighter color than in the surrounding outer shell section thereof, said method comprising the steps of a. unstacking an entire first layer of bricks from said stack, said layer including a corresponding core section and shell section, b. unstacking an entire second layer of bricks from said stack, said layer including a corresponding core section and shell section, c. transporting said second layer to a rearranging position, d. rearranging bricks within said second layer with respect to each other, to place bricks from the normally occurring core section areas into the normally occurring shell section areas and vice versa, e. transporting said first and second layers to a restacking position, f. restacking said first and second layers of bricks, g. repeating said unstacking, transporting, and rearranging steps until a new stack is formed having increased uniformity in the spatial distribution of bricks having different hardness and color characteristics.
Claim 2
Independent Claim
181 words
A method for blending a stack of bricks comprising a plurality of vertically superimposed layers, each layer comprising a plurality of bricks, said stack having a central core section of lesser hardness and lighter color than in the surrounding outer shell section thereof, said method comprising the steps of a. unstacking an entire first layer of bricks from said stack, said layer including a corresponding core section and shell section, b. unstacking an entire second layer of bricks from said stack, said layer including a corresponding core section and shell section, c. transporting said second layer to a rearranging position, d. rearranging bricks within said second layer with respect to each other, to place bricks from the normally occurring core section areas into the normally occurring shell section areas and vice versa, e. transporting said first and second layers to a restacking position, f. restacking said first and second layers of bricks, g. repeating said unstacking, transporting, and rearranging steps until a new stack is formed having increased uniformity in the spatial distribution of bricks having different hardness and color characteristics.
Claim 3
Dependent Claim
45 words
A method as recited in claim 1 wherein said step of rearranging bricks within said second layer with respect to each other is accomplished by rotating about a vertical axis a plurality of bricks within said layer with respect to other bricks in said layer.
Claim 4
Dependent Claim
45 words
A method as recited in claim 2 wherein said rearranging step is further accomplished by rotating bricks in a first half of said layer 180° about said vertical axis, and rotating bricks in a second half of said second layer 180° about said vertical axis.
Claim 5
Dependent Claim
19 words
A method as recited in claim 1 wherein said first and second layers are each only one brick high.
Claim 6
Dependent Claim
52 words
A method as recited in claim 1 comprising the further steps of transporting said first layer to a rearranging position, and rearranging bricks within said first layer with respect to each other to place bricks from the normally occurring core section areas into the normally occurring shell section areas and vice versa.
Claim 7
Dependent Claim
44 words
A method as recited in claim 5 wherein said steps of rearranging bricks within said first and second layers are accomplished by rotating about a vertical axis a plurality of bricks within each said layer with respect to other bricks in each said layer.
Claim 8
Dependent Claim
26 words
A method as recited in claim 5 wherein said rearranging step is accomplished by transposing predetermined groups of bricks within each said first and second layers.
Claim 9
Dependent Claim
23 words
A method as recited in claim 1 wherein said rearranging step is accomplished by transposing predetermined groups of bricks within said second layer.
