Abstract
Abstract Green brick newly formed by pushing a slug through a wire cutter, have their longitudinal edges shaped by means of a plurality of rollers positioned above and across the path of conveyance of the bricks so that each roller simultaneously engages the adjacent edges of two adjacent bricks. The shape imparted to the brick edges is governed by the shape of the peripheral portions of the rollers. The rollers are mounted on a shaft at fixed locations along the shaft in alignment with the wires of the wire cutter. Before operation the locations of the rollers along the shaft may be adjusted through spacers in order to adapt the rollers to different sizes of bricks. The roller mounting shaft may be adjusted in a vertical plane towards or away from the conveyor path to adjust the depth of the rollers for a specific operation or to sufficiently raise the rollers away from the conveyor path where they may be kept idle when not in use. The shaping of the edges of the bricks causes brick material to adhere between adjacent bricks immediately below the edges which have been shaped. Accordingly, a plurality of cutter members are provided across the path of conveyance to enter between the rows of bricks to sever the adhering material between the bricks. The cutter members are mounted on individual arms which, in turn, are mounted on a cross member overlying said path such that the arms are movable transversely of the path. The cross member is adjustable in a vertical plane towards and away from the conveyor path to adjust the depth of the cutting member for a specific operation or to merely place them in an idle position when not in use.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
157 words
In combination with apparatus for cutting slugs into rows of green bricks including a wire cutter having a plurality of horizontally spaced fixed generally vertical wires extending across a path of conveyance in side-by-side relationship, means for shaping the edges of the bricks after leaving the wire cutter including a plurality of rollers mounted for rotation about a horizontal axis extending across the path of conveyance, the rollers being position along said axis at fixed locations aligned with said wires, respectively, such that peripheral portions of each roller will simultaneously engage the adjacent edges of adjacent bricks to shape the same, and wherein said rollers have means on their peripheral portions for shaping the edges of the bricks, and wherein the apparatus further includes cutting means positioned along the path of conveyance downstream of the rollers for cutting portions of the bricks located between adjacent rows of bricks for separating the rows of bricks from each other.
Claim 2
Dependent Claim
157 words
In combination with apparatus for cutting slugs into rows of green bricks including a wire cutter having a plurality of horizontally spaced fixed generally vertical wires extending across a path of conveyance in side-by-side relationship, means for shaping the edges of the bricks after leaving the wire cutter including a plurality of rollers mounted for rotation about a horizontal axis extending across the path of conveyance, the rollers being position along said axis at fixed locations aligned with said wires, respectively, such that peripheral portions of each roller will simultaneously engage the adjacent edges of adjacent bricks to shape the same, and wherein said rollers have means on their peripheral portions for shaping the edges of the bricks, and wherein the apparatus further includes cutting means positioned along the path of conveyance downstream of the rollers for cutting portions of the bricks located between adjacent rows of bricks for separating the rows of bricks from each other.
Claim 3
Dependent Claim
35 words
The apparatus defined in claim 1 wherein opposite sides of each roller adjacent the periphery thereof have concave surface portions merging into the peripheral edge of the roller for imparting rolled edge portions to bricks.
Claim 4
Dependent Claim
44 words
The apparatus defined in claim 2 wherein a number of the rollers each have a first set of projections at spaced locations about their peripheral edges and additional projections on opposite sides thereof adjacent the peripheral edges for shaping the edges of the bricks.
Claim 5
Dependent Claim
51 words
The apparatus defined in claim 1 wherein said cutting means includes a plurality of individual cutting members spaced across the path of conveyance for receipt between adjacent rows of bricks to sever material adhering between adjacent rows of bricks as a result of the shaping of the edges by the rollers.
Claim 6
Dependent Claim
113 words
Apparatus for shaping and handling newly formed green brick during conveyance in rows along a path, the apparatus comprising in combination; a plurality of forming members positioned above and across said path to be engageable with and between adjacent bricks of adjacent rows to shape the upper edges of the bricks with each forming member simultaneously shaping the adjacent edges of adjacent rows of bricks, and means downstream of the forming members for entering between adjacent rows of bricks for severing material adhering to adjacent bricks resulting from the shaping of the edges thereof, and wherein said forming members are rollers mounted for rotation about a common horizontal axis extending across said path.
Claim 7
Dependent Claim
113 words
Apparatus for shaping and handling newly formed green brick during conveyance in rows along a path, the apparatus comprising in combination; a plurality of forming members positioned above and across said path to be engageable with and between adjacent bricks of adjacent rows to shape the upper edges of the bricks with each forming member simultaneously shaping the adjacent edges of adjacent rows of bricks, and means downstream of the forming members for entering between adjacent rows of bricks for severing material adhering to adjacent bricks resulting from the shaping of the edges thereof, and wherein said forming members are rollers mounted for rotation about a common horizontal axis extending across said path.
Claim 8
Dependent Claim
