Abstract
1485888 Squares TIN WAH-CHEUNG 1 Dec 1975 [1 Oct 1975] 40066/75 Heading G1X An adjustable try-square comprises a blade 2 pivotted by a pin 8 to the stock 1 which has two holes, one carrying a spring 5-loaded push-rod 3 held by a set screw 6 and the other carrying an adjusting rod 4 and screw 7, a dial being mounted on the end of the stock around the screw 7 for indicating the amount of displacement of the rod 4 when the screw 7 is turned. The outer edge of the blade is arcuate and the blade is held in a slot 11 of the stock which is I-shape in section; the screw 7 has 40 t.p.i. and the dial has 25 divisions, so that a turn through one division.of the screw 7 moves the rod 4 by 0À001 inch.
