发明名称 Brick line tool
摘要 A pair of flat plates with two rectangular sides provide corner pieces which fit over the top edges of bricks at opposite ends of a structure. Each plate includes a raised tab and extending finger which receive a line or string to be held taut between the two end pieces. The string serves as a linear guide for laying bricks in a straight line between the two ends. The device provides a simplified tool which saves time and effort in achieving the desired linear brick construction.
