Patent number: 9482509Abstract: A micrometer provides a quick adjustment mode and a fine adjustment mode. A spline-like rotary coupling configuration constrains the micrometer thimble and a threaded element to move together with respect to rotation, but does not constrain the position of the threaded element relative to the thimble along the measurement axis. A gear in the micrometer frame includes gear teeth that mesh with the threaded element and roll thereon along the measurement direction. A locking arrangement, when unlocked, allows the meshed gear to be rotated by a user to drive the threaded element along the measuring axis in the quick adjustment mode. When locked, the locking arrangement prevents motion of the gear to provide the fine adjustment mode, wherein the user rotates the thimble to screw the threaded element through the meshed teeth of the gear, to adjust the spindle position.Type: GrantFiled: December 12, 2014Date of Patent: November 1, 2016Assignee: Mitutoyo CorporationInventor: Kim W.

Patent number: 5052121Abstract: A computerized gauge measures dimensions, typically in the range of 6.1865" to 6.1917" accurate to .+-.0.001", typically the diameter of a steel railroad car axle. The gauge simultaneously senses the temperature, typically within a range of -20.degree. F. to 100.degree. F.+1.degree. F., of the axle workpiece. In consideration of the predetermined coefficient of expansion of the workpiece, the gauge calculates the dimension that the workpiece would exhibit should it be thermally brought to a predetermined, 59.degree. F. by convention, reference temperature. From the workpiece-temperature-compensated dimension resulting from such calculation, the axle may be recognized as being (i) oversized but repairable, (ii) within an acceptable size range, (iii) undersized but repairable, or (iv) undersized and unrepairable.Type: GrantFiled: July 13, 1990Date of Patent: October 1, 1991Assignee: Albion Devices, Inc.Inventor: William R.
