Abstract

807,495. Gauging screw-threads. SVENSKA PRECISIONVERKTYG A.B. June 3, 1957 [June 14, 1956], No. 17548/57. Class 106 (2). A screw-thread gauge comprises two screwthreads 12, 22 formed on mutually rotatable bodies 10, 20 at the end of a tube 10 and spindle 18, the spindle being rotatable within the tube 10 to an initial position in which the two screw threads 12, 22 form a continuation, the one of the other and the spindle being formed with a coniform portion 28 urged by a spring 70 to bear against a coniform seat 30 in the tube 10. A clearance is allowed between the spindle 18 and tube 10 from the conical bearing 30 to a bearing 32 spaced a distance several times the diameter of the spindle. Relative rotation between the spindle 18 and tube 10 is limited by a pin 52 working in two diametricallyopposed notches 50 and is indicated by a main scale 78 on the tube 10 in co-operation with a vernier scale 76 on a hood 56, detachably connected to the spindle 18 by chuck means 61, 62, 64, which can be released to allow a zero adjustment to be made to eliminate errors due to wear.
