Abstract
Abstract A novel and improved brick setting machine as disclosed, which is operable to automatically produce stacks of green brick suitable for firing and which have a high degree of stability to permit their being transported from one location to another by fork lift trucks or the like. The stack includes a plurality of grids of brick, some of which consist of lengthwise aligned rows of brick spaced from each other by longitudinal lanes and crosswise rows of aligned brick, extending perpendicular to the lengthwise rows wherein at least some of the brick in the crosswise rows are spaced from each other to form lateral lanes. The patterns within the grids are arranged so that the lateral and lengthwise lanes are superimposed so that the patterns of lengthwise brick and crosswise brick can be consolidated into the desired grids by automatic means including grippers which extend along the longitudinal and lateral lanes. The pattern of grids is arranged to provide a high degree of tieing between the various rows of brick, making up the stack so that the entire stack is highly stable. The bottom grid is soldier set to permit gripping and transfer of the entire grid by fork truck or the like. The machine for forming the stack includes a first subassembly for establishing the patterns of lengthwise rows of brick and a second sub-assembly for establishing the corresponding patterns of crosswise rows of brick.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
193 words
A machine for forming stacks of brick or the like having grids including intermixed first rows of lengthwise aligned brick and second rows of lengthwise aligned brick extending perpendicular to said first rows comprising first means for forming first patterns of first rows with longitudinal lanes between at least some of said first rows, second means for forming second patterns of said second rows with at least one lateral lane between the end faces of brick and said second rows, said first means operating to produce a plurality of different patterns which are combinable with related patterns formed by said second means to form grids including first and second rows, and transfer means operable to grip an entire pattern of rows along said lanes and to transfer and deposit such patterns at a stacking location, said transfer means thereafter operating to grip an entire related pattern of rows along its lane and to transfer and deposit such pattern in a prior pattern of rows with the lane thereof along one of the lanes of such prior pattern, without interfering with the brick in such prior pattern adjacent to said one of said lanes.
Claim 2
Dependent Claim
193 words
A machine for forming stacks of brick or the like having grids including intermixed first rows of lengthwise aligned brick and second rows of lengthwise aligned brick extending perpendicular to said first rows comprising first means for forming first patterns of first rows with longitudinal lanes between at least some of said first rows, second means for forming second patterns of said second rows with at least one lateral lane between the end faces of brick and said second rows, said first means operating to produce a plurality of different patterns which are combinable with related patterns formed by said second means to form grids including first and second rows, and transfer means operable to grip an entire pattern of rows along said lanes and to transfer and deposit such patterns at a stacking location, said transfer means thereafter operating to grip an entire related pattern of rows along its lane and to transfer and deposit such pattern in a prior pattern of rows with the lane thereof along one of the lanes of such prior pattern, without interfering with the brick in such prior pattern adjacent to said one of said lanes.
Claim 3
Dependent Claim
36 words
A machine for forming stacks of brick or the like as set forth in claim 1 wherein said first patterns are gripped first and said second patterns are gripped subsequently and positioned within said first patterns.
Claim 4
Dependent Claim
43 words
A machine for forming stacks of brick or the like as set forth in claim 2 wherein said first means includes a spreader operable to receive a column of abutting brick and to spread the brick in such column to provide spaces therebetween.
Claim 5
Dependent Claim
46 words
A machine for forming stacks of brick or the like as set forth in claim 3 wherein said first means includes a transfer means operable to transfer bricks from said spreader, and said spreader and transfer means operate with repeated cycles to establish said first pattern.
Claim 6
Dependent Claim
44 words
A machine for forming stacks of brick or the like as set forth in claim 4 wherein said spreader and transfer means are operable to establish a plurality of different first patterns by changing the spacing between said first rows in said first patterns.
Claim 7
Dependent Claim
40 words
A machine for forming stacks of brick or the like as set forth in claim 5 wherein said transfer means is a pusher and said pusher includes means operable to push selected brick from said spreader to provide different patterns.
Claim 8
Dependent Claim
61 words
