  • Modular mechanical bore gauge system
    Patent number: 10788302
    Abstract: The modular bore gauge system comprises a plurality of modular spring-loaded bore gauge head adaptors, each having a bore gauge head on a first end thereof and having a female threaded second end, a plurality of modular spring-loaded depth extensions, each having a first male threaded end and a second female threaded end and configured to have its first end screwed onto the second end of one bore gauge head adaptors or to have its first end screwed onto the second end of another one of the depth extensions, and a modular indicator adaptor, configured to have an indicator fitted on a first end thereof and a male threaded second end and configured to have its second end screwed onto the second end of one of the bore gauge head adaptors or screwed onto the second end of a last in line of one of the depth extensions.
    Type: Grant

  • Contour probe linkage for a horizontal beam optical comparator
    Patent number: 9797713
    Abstract: The present disclosure describes an improved horizontal beam optical comparator that includes a probe to follow the surface of a work-piece, moreover, providing a method for gathering changes in height and depth to measure, plot and delineate surface contours of work-pieces relative to a movable “X” axis stage, and depth along a moveable “Y” axis stage without presence in the objective lenses depth of field.
