  • Mechanism for measuring distances especially thread diameters
    Patent number: 4453316
    Abstract: The object to be measured (2) is placed on carrier (1). Measuring pins (7,8) can be adjusted roughly in terms of height after loosening screws (11). Sliding carriages (5,6) are guided movably by spherical guides in measurement support members (3,4) perpendicularly to the direction of measurement. Measuring pins (7,8) located in support members (3,4) which are provided with handles (13) and which are connected with sliding carriages (5,6) by means of leaf springs (14). If the laterally adjustable support member (4) is moved into the measuring position, the sliding carriages (5,6) with their measuring pins (7,8) can, within the limits of leaf springs (14), be freely centered in the pitch of the thread to be measured (2a) thus providing the ideal prerequisites for correct measurement of the thread diameter.
