Abstract: A measuring apparatus for measuring the interference or height of semicylindrical articles such as shell-type half bearings or the like in which the articles to be measured are adapted to be disposed in a shape-conforming cavity of a bearing cap with one parting edge surface of the bearing being supported by the framework of the apparatus. A reciprocable gaging block incorporating a gaging surface is movable to and from a measuring position and a clearance position by means of a motor and cam carrier assembly which is biased toward the gaging block under a preselected load and the eccentric cam thereon effects an intermittent reciprocation of the gaging block to and from the measuring position. Biasing means are provided for continuously biasing the gaging block toward a nonmeasuring position. A probe is provided for sensing the interference or height of a bearing being measured in response to the disposition of the gaging surface relative to the bearing cap when the gage block is in the measuring position.

Abstract: A self-piercing needle valve having a body and a shank is adapted for mounting upon a pipe. A valve support plate extends transversely of and is secured to said shank and has a right-angle extension at one end. Said extension along its length on one side has a series of variably spaced parallel wedge-shaped slots corresponding to different pipe diameters. The support plate is adapted to extend transversely of and bear against one side of a pipe. An anchor plate is spaced from and opposed to the support plate and adapted to bear against the opposite side of said pipe. A transverse slot through one end of the anchor plate is adapted to loosely receive said extension upon one side of the pipe, with portions of said anchor plate bounding said slot retainingly nested within one of said notches. A fastener upon the other side of the pipe extends between and interconnects the opposing ends of said plates for drawing the plates together and for gripping the pipe therebetween.
