Abstract: A mount for mounting a measuring instrument, such as an electronic measuring transducer. The mount includes a spring operated clamp assembly for attaching the mount to a first part with a reference surface engaging a desired location on the first part. In one embodiment, the clamp assembly grips the first part between a clamp member and a clamp portion. The mount has an unclamping member which may be operated with one hand to selectively open the clamp. In another embodiment, the clamp assembly includes a first clamp member and a second clamp member urged by a spring relatively away from the first clamp member, each of the first and second clamp members having a grip by which the first and second clamp members may be urged together then selectively released to clamp the mount in a gap between the first part and a second part.

Abstract: A gage according to the present invention for use in measuring engagement parts of a pneumatic hose coupler and including a body and a spring loaded contact rotatably mounted to the body. The body includes an alignment part for locating the gage on the coupler and a member for contacting one of the engagement parts. The contact is biased into contact with another of the engagement parts and calibrated indicator marks provide a visual indication of the angular distance between the two parts. Sights through the gage measure another angular dimension between coupler engagement parts. The gage also includes a plug part for measuring vertical clearance between other parts of the coupler.
