Abstract

An instrument which is an aid for marking out rectangles or other geometric figures consists of a sheet (1) of material such as aluminium. The sheet has rows of holes (4) spaced one cm apart, and one edge (1b) of the sheet is bent at right angles. The instrument is placed over a board or other article which is to be marked with the flange (1b) abutting against the edge of the board. The corners of the required rectangle are then marked out by inserting a special punch into the appropriate holes.
