Abstract
Abstract A stacking assemblage fed from a conveyor which transports materials to a staging area. The materials are formed into a tier on a movable platen of the assemblage in accordance with a prescribed pattern. The platen can be raised or lowered to a desired level and then shifted to deposit each tier on an outboard conveyor until a desired multi-tier stack is formed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A stacking assemblage comprising a movable platen for supporting materials received at a first position; a guide member transversely movable with respect to said platen against which said materials are arranged in a tier in accordance with a prescribed pattern; means for transversely moving said guide member away from said tier; means for shifting said platen through the position previously occupied by said guide member to overlie a second position; said guide member being displacable in the direction of motion of said platen when said platen is shifted to overlie said second position; and the shifting means depositing said tier at said second position as a constituent of a multi-tier stack by drawing said tier against said guide member.
Claim 2
Dependent Claim
119 words
A stacking assemblage comprising a movable platen for supporting materials received at a first position; a guide member transversely movable with respect to said platen against which said materials are arranged in a tier in accordance with a prescribed pattern; means for transversely moving said guide member away from said tier; means for shifting said platen through the position previously occupied by said guide member to overlie a second position; said guide member being displacable in the direction of motion of said platen when said platen is shifted to overlie said second position; and the shifting means depositing said tier at said second position as a constituent of a multi-tier stack by drawing said tier against said guide member.
Claim 3
Dependent Claim
22 words
A stacking assemblage as defined in claim 1 wherein said first position and said second position are at the same operational level.
Claim 4
Dependent Claim
33 words
A stacking assemblage as defined in claim 1 wherein said second position is laterally displaced from and below said first position; and said platen can be elevated above and below said first position.
Claim 5
Dependent Claim
36 words
A stacking assemblage as defined in claim 1 wherein said second position is laterally displaced from said first position and the shifting means comprises means for laterally moving said platen to and above said second position.
Claim 6
Dependent Claim
20 words
A stacking assemblage as defined in claim 1 wherein said platen temporarily supports said tier in a prescribed pattern thereon.
Claim 7
Dependent Claim
17 words
A stacking assemblage as defined in claim 1 including a further guide member associated with said platen.
Claim 8
Independent Claim
81 words
A method of stacking materials comprising the steps of a. forming a tier of materials in a prescribed pattern from materials received at a first position upon a movable platen and against a guide member; b. retracting said guide member transversely with respect to said platen and shifting said platen with said tier thereon to overlie a second position; and c. moving said guide member in the direction of movement of said platen and depositing said tier at said second position.
Claim 9
Independent Claim
81 words
A method of stacking materials comprising the steps of a. forming a tier of materials in a prescribed pattern from materials received at a first position upon a movable platen and against a guide member; b. retracting said guide member transversely with respect to said platen and shifting said platen with said tier thereon to overlie a second position; and c. moving said guide member in the direction of movement of said platen and depositing said tier at said second position.
Claim 10
Dependent Claim
36 words
The method of claim 7 wherein said guide member is repositioned transversely after said platen has been shifted, and said tier is deposited by withdrawing said platen with said tier in contact with said guide member.
Claim 11
Dependent Claim
27 words
The method of claim 7 wherein said guide member is movable transversely to said platen simultaneously with its movement in the direction of movement of said platen.
