Automatic brick or concrete block laying appts. for wall making - successively positions block units beneath gripping head which deposits it on laterally moving table

摘要

Block units are successively and intermittently moved into an exact position where each one is gripped by a gripping head. A table which is mounted for lateral movement and movement normal thereto is shifted into position beneath the gripped block, following which the block is deposited on the table. While the next block unit is being gripped, the table is shifted laterally so that the next block is deposited at the end of the previously-deposited block. Mortar is placed against the adjacent ends of these blocks in any desired manner, and the last-mentioned block is shifted back towards the first block far enough to leave only the desired thickness of mortar.
