Universally mounted perspective drawing apparatus - has sloping rod carrying joints for follower system and view point table

摘要

The apparatus for making perspective drawings has a table (1) which can be mounted at an angle and on which an object to be drawn is placed. A slide (2) in front carries an indexing member so as to follow the shape of the object. It is mounted on an arm (10) attached to a universal joint (4) around a rod (6) sloping at an angle to the vertical. This rod also passes through a second universal joint (5) attached to an auxiliary table (11) on which is located the view point. This rod finally passes through a level lower surface. The second universal joint can be removed from the auxiliary table and the rod mounted on a vertical guide for a different axis.
