Abstract

1311912 Perspective drawing apparatus MAISON WUILLEME 8 July 1970 [10 July 1969] 33065/70 Heading B6P Perspective drawing apparatus includes a T-square arrangement comprising a stiff-rod 4 mounted on a carriage 6 arranged to slide on a stiff-rod 7 at right-angles thereto. A straight edge or rule 2 is pivoted to a carriage 3 arranged to slide on rod 4. An arm 10 is adjustably, slidably and pivotally mounted at 12 on the edge of the drawing-board. The end 13 of the arm 10 is slidably and pivotably mounted to the straight edge 2. With the arm 10 set in its desired position, 13 constitutes the vanishing point. A straight edge 2<SP>1</SP> and an arm 11 are provided on the other side of the rod 4. In a modification (Figs. 6 and 7), the two straight edges 2 and 2<SP>1</SP> can be locked to the carriage 3 at right-angles to the rod 4 so that the horizon can be drawn. To counteract sagging of the vanishing points 13, the pivots at 12 have a screw adjustment which raises and lowers the arms 10 and 11 with respect to the surface of the drawing board.
