Abstract
Abstract Brick stacked in courses comprised of double-layer rows within which the face sides of the individual pairs of superposed bricks may be confronting are dehacked by sequentially removing complete successive courses from each stack, and pairing courses from the upper and lower portions of the stacks such that the respective double-layer rows thereof are in alignment. Successive doublelayer rows are then removed simultaneously from each pair of courses, and the upper layer of each such unit is everted and aligned with the lower layer to form a single-layer line of bricks all having their face sides facing upwardly and alternating in row groupings between bricks from the upper portions of the stacks and bricks from the lower stack portions. The blending of the bricks eliminates marked color gradients sometimes present in the original stacks.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A method of dehacking bricks arranged in stacks each having in its upper and lower portions a plurality of courses comprised of a plurality of double-layer rows of bricks, the bricks in the upper layer of each double-layer row having downwardly facing face sides engaging upwardly facing face sides of the bricks in the lower layer of the row, comprising the steps of: removing successive courses from the stacks; pairing each course removed from each one of the stack portions with a course removed from the other of the stack portions such that the double-layer rows of each of the paired courses are in longitudinal alignment; separating successive aligned double-layer rows, as individual double-layer units, from the paired courses; everting one of the layers of each separated double-layer unit and longitudinally aligning the everted layer and the other layer of the unit to form a single-layer line of row-blended bricks each having their face sides extending in the same direction.
Claim 2
Independent Claim
160 words
A method of dehacking bricks arranged in stacks each having in its upper and lower portions a plurality of courses comprised of a plurality of double-layer rows of bricks, the bricks in the upper layer of each double-layer row having downwardly facing face sides engaging upwardly facing face sides of the bricks in the lower layer of the row, comprising the steps of: removing successive courses from the stacks; pairing each course removed from each one of the stack portions with a course removed from the other of the stack portions such that the double-layer rows of each of the paired courses are in longitudinal alignment; separating successive aligned double-layer rows, as individual double-layer units, from the paired courses; everting one of the layers of each separated double-layer unit and longitudinally aligning the everted layer and the other layer of the unit to form a single-layer line of row-blended bricks each having their face sides extending in the same direction.
Claim 3
Dependent Claim
41 words
A method as in claim 1, wherein the stacks have alternating header-oriented and stretcher-oriented courses, and further including changing the orientation of alternate ones of the courses removed from the stacks to the orientation of the other courses before pairing thereof.
Claim 4
Dependent Claim
22 words
A method as in claim 1, and further including compacting each course in the row direction during removal thereof from a stack.
Claim 5
Dependent Claim
49 words
A method as in claim 1, wherein the step of pairing the courses includes directing all those from upper stack portions along a first path of travel and directing all those from lower stack portions along a second path of travel disposed parallel to and closely said first path.
Claim 6
Dependent Claim
74 words
A method as in claim 1, wherein the steps of everting and aligning include raising the upper layer of each separated double-layer unit out of engagement with the lower layer thereof, rotating the raised upper layer approximately 180* about an axis extending longitudinally therethrough, moving the lower layer longitudinally from beneath the vertical projection of the raised upper layer, and lowering the upper layer into a position of longituidinal alignment with the lower layer.
Claim 7
Dependent Claim
165 words
Apparatus for dehacking bricks arranged in stacks each having in its upper and lower portions a plurality of courses comprised of a plurality of double-layer rows of bricks, the bricks in the upper layer of each double-layer row having downwardly facing face sides engaging upwardly facing face sides of the bricks in the lower layer of the row, comprising: means for removing successive courses from the stacks; means for pairing each course removed from each one of the stack portions with a course removed from the other of the stack portions such that the double-layer rows of each of the paired courses are in longitudinal alignment; means for separating successive aligned double-layer rows, as individual double-layer units, from the paired courses; and means for everting one of the layers of each separated double-layer unit and longitudinally aligning the everted layer and the other layer of the unit to form a single-layer line of row-blended bricks each having their face sides extending in the same direction.
Claim 8
Dependent Claim
165 words
Apparatus for dehacking bricks arranged in stacks each having in its upper and lower portions a plurality of courses comprised of a plurality of double-layer rows of bricks, the bricks in the upper layer of each double-layer row having downwardly facing face sides engaging upwardly facing face sides of the bricks in the lower layer of the row, comprising: means for removing successive courses from the stacks; means for pairing each course removed from each one of the stack portions with a course removed from the other of the stack portions such that the double-layer rows of each of the paired courses are in longitudinal alignment; means for separating successive aligned double-layer rows, as individual double-layer units, from the paired courses; and means for everting one of the layers of each separated double-layer unit and longitudinally aligning the everted layer and the other layer of the unit to form a single-layer line of row-blended bricks each having their face sides extending in the same direction.
Claim 9
Dependent Claim
98 words
Apparatus as in claim 6, wherein said pairing means includes first and second elongate course-supporting means extending in laterally adjacent and parallel relationship to each other, means for loading courses from the upper stack portions onto one of said supporting means and courses from the lower stack portions onto the other of said supporting means, first and second pusher members movable independently and in out of phase relationship relative to each other longitudinally of said first and second supporting means respectively for moving courses supported thereby away from said loading means and toward said everting and aligning means.
Claim 10
Dependent Claim
43 words
Apparatus as in claim 7, wherein said course supporting means comprises first and second roller conveyors, and said loading means includes a ram assembly translatorily movable adjacent one end of said roller conveyors to alternative positions of alignment therewith for loading courses thereon.
Claim 11
Dependent Claim
54 words
Apparatus as in claim 6, wherein said everting and aligning means includes a clamp assembly adapted to engage end portions of said one layer of each double-layer unit of bricks, and means mounting said clamp assembly for linear translatory movement in a vertical direction and for rotational movement about an axis translatorily movable therewith.
Claim 12
Dependent Claim
37 words
Apparatus as in claim 9, wherein said everting and aligning means further includes a delivery conveyor adapted to support said line of row-blended bricks, said clamp assembly being mounted for said movement thereof above said delivery conveyor.
