Radius-setting gauge

Claim 1

A radius-setting gauge for use with a radius dresser having a frame, a rotary spindle in said frame, and a dressing element rotatable with and adjustable radially of said spindle, said gauge comprising: a rigid arm; means for attaching said arm to the frame of said dresser in accurately located position with one end portion located in the plane of rotation of the element; a micrometer carried by said arm at the said one end portion and having an adjustable stem extending toward the element; a slide mounting said micrometer for sliding movement therewith relative to said arm in a direction radially of the spindle of the dresser; a dial indicator carried by said arm having a plunger operatively coupled with said slide; and a setup pin for said dresser adapted to be mounted as an extension of the dresser spindle, said pin having a head provided with opposed setup surfaces of known equal spacing from the axis of said pin in position to engage the stem of said micrometer.

Claim 6

The method of adjusting a radius dresser having a frame, a rotary spindle in said frame, and a diamond support rotatable with and adjustable radially of said spindle to a required radius which comprises mounting directly on the radius dresser frame in fixed position an arm supporting a micrometer having a stem extending radially toward the axis of said spindle and a measuring device, said micrometer being bodily movable radially of the axis of said spindle parallel to the direction of movement of said stem, said measuring device having an extending stem movable upon movement of said micrometer; mounting on said diamond support a setup pin having a pair of opposed surfaces spaced apart in a direction perpendicular to the axis of said spindle; setting said micrometer to extend the stem in position to be engaged by said pin; moving said diamond support toward said micrometer to displace said micrometer by engagement between one of said surfaces and the end of said stem, reading the indicated position of said micrometer on said measuring device while the micrometer is positioned by engagement with said pin; rotating said spindle to bring the other of said surfaces into engagement with the stem of said micrometer; measuring the second position of said micrometer; adjusting said diamond support until the two positions of said micrometer are identical to determine a zero micrometer position; replacing said setup pin with a dressing diamond, setting said micrometer to a dimension corresponding to the required radius setting for said diamond, after the two indicated positions are identical, zeroing the measuring device to provide for a zero reading thereof when said diamond is adjusted to move the micrometer to a preset dimension thereof; and adjusting said diamond support to displace said micrometer to its zero position.

Claim 7

The method of adjusting a radius dresser having a frame, a rotary spindle in said frame, and a diamond support rotatable with and adjustable radially of said spindle to a required radius which comprises mounting directly on the radius dresser frame in fixed position an arm supporting a micrometer having a stem extending radially toward the axis of said spindle and a measuring device, said micrometer being bodily movable radially of the axis of said spindle parallel to the direction of movement of said stem, said measuring device having an extending stem movable upon movement of said micrometer; mounting on said diamond support a setup pin having a pair of opposed surfaces spaced apart in a direction perpendicular to the axis of said spindle; setting said micrometer to extend the stem in position to be engaged by said pin; moving said diamond support toward said micrometer to displace said micrometer by engagement between one of said surfaces and the end of said stem, reading the indicated position of said micrometer on said measuring device while the micrometer is positioned by engagement with said pin; rotating said spindle to bring the other of said surfaces into engagement with the stem of said micrometer; measuring the second position of said micrometer; adjusting said diamond support until the two positions of said micrometer are identical to determine a zero micrometer position; replacing said setup pin with a dressing diamond, setting said micrometer to a dimension corresponding to the required radius setting for said diamond, after the two indicated positions are identical, zeroing the measuring device to provide for a zero reading thereof when said diamond is adjusted to move the micrometer to a preset dimension thereof; and adjusting said diamond support to displace said micrometer to its zero position.
