Abstract: 1,102,240. Stacking bricks; mobile-lifting apparatus. P. S. KELSEY. 24 Dec., 1965 [17 Sept., 1965], No. 54892/65. Headings B8C and B8H. A stack of unbaked bricks 42 consists of superimposed courses 44, 46, the courses being arranged in alternate pairs of header and stretcher courses with a stabilizer plate, which may comprise nine plates 54 joined together by metal or refractory rings or U-shaped devices 56 or by tongues and grooves on top of the stack to stabilize it during the drying and heating of the bricks in the kiln. The stabilizer plate may be a sheet of wire mesh. Additional plates may be placed between the intermediate courses of the stack. The bricks are made from a bar of clay (60), Fig. 6 (not shown), which is cut into blocks by a cutter (62). The blocks are spaced and fed by a conveyer (63) in front of a pusher (65) which feeds them to a table (66). When a complete course has been formed on the table, the table moves to a position adjacent a pickup head (67), Fig. 5 (not shown). The course of bricks is removed from the table either directly by vacuum pads on the pick-up head which can be lowered on to the table, or by vacuum pads on a turner (70) which has a pair of pick-up heads (68), (69), which can pick up a course of bricks and turn it through 180 degrees. The pick-up head is mounted on a carriage so that the head can be moved over a kiln car where the course is lowered into the car. The pick-up head can rotate horizontally through 90 degrees to position the courses in header or stretcher arrangement. The pick-up heads space the rows of bricks before lowering them into the kiln car. When the stack in the kiln car is complete, the car is moved to a position where a supply of plates 54 is stacked. One plate 54 is picked up by a pick-up head mounted on a carriage which transfers one plate 54 from the stack of plates on to the top of each stack of bricks in the kiln car. The operation of the brick and plate setting apparatus may be remotely controlled by an operator or automatically. After the baking of the bricks, first the plates 54 and then each course of bricks can be unloaded from the cars by similar apparatus to the loading apparatus only operating in reverse.
