Abstract

996,095. Angle-measuring instruments. R. BUSI. March 12, 1963 [July 27, 1962], No. 9706/63. Heading G1X. A device for testing the squareness between two plane surfaces comprises a base 1 for standing on one of the two surfaces and having a pair of columns 2 upstanding therefrom so as to be perpendicular to the first surface, a carrier 4 slidably mounted on the columns 2 and carrying a spring pressed probe 6 for engaging the other surface so that deviations of the second surface from perpendicularity with the first surface are indicated on dial 13. The carrier 4 surrounds sleeve 3 on one column 2 and is forked at 10 to engage the sleeve 3a on the other columns to allow for unequal thermal expansion of base 1 and carrier 4. A handwheel 9 actuating bevel gears 8 which rotate a screw 7, causes raising and lowering of the carrier 4 or alternative mechanical or electrical driving means may be used.
