STARRETT No.10 Inclinometer Combination Tool *SOLD*
A scarce STARRETT No 10 inclinometer, try square and bevel protractor combination tool.
The 1924 STARRETT catalogue states:
"The above cut represents an inclinometer try square and bevel protractor combined. It is compact, convenient, and a complete and perfect substitute for several costly tools. It consists of a stock and disc both slotted to receive the blade, which folds into the stock. The blade attached to the graduated rotary disc may be secured at any angle from 0 to 90 degrees, and by loosening the clamp screw it may be shortened or extended full length, or removed for straight edge. The working face of the stock, extending both sides of the blade, admits of its being reversed, so that the same angle may be laid off in opposite directions without changing the angle in the tool, thus requiring but 1/4 of a graduated circle to obtain all angles both ways. At 90 degrees, the blade brings up against a case-hardened screw, accurately adjusted, thus forming a try square; by holding the blade perpendicular (the level in the stock being at right angles), a plumb; by folding the tool, a level, length of blade."
Marked 'PAT.AUG 7 1883' on the stock and stamped '152' on both the stock and disc.
