This scale is intended to take the place of the ordinary boxwood scale with diagonal ruling, which is usually 

 found in boxes of drawing instruments, but are practically useless. The illustration shows the top side, one 

 edge of which is divided into inches and izths, 24ths, etc., and the other edge into inches and loths, 2oths, etc. 

 The middle part is divided so that with beam compasses any measurement up to 13 inches may be taken off in 

 T J 5 ths of an inch. The other side is divided into millimetres on one edge, and into inches, i6ths, 32nds, etc., 

 on the other edge, and the centre part is for beam compasses to one-tenth of a millimetre (steel nickel-plated).
