G01B 5/12

US Classification:

33611, 33542, 335445, 335551

Abstract:

A gauge device for measuring the inner diameter of engine related bores comprising a circular body member having a circumferential surface with a cylindrical chamber totally encased therein along a longitudinal axis. A slide pin is housed within the cylindrical chamber which partially extends through upper and lower openings within the circumferential surface. A top flange extends radially from the upper portion of the body member and having a cylindrical dial mount affixed to the front. Disposed equidistance to each side of the top flange is a secondary flange extending radially from the front of the body member each embedded with a magnetic disk. A vertical slot positioned along the longitudinal axis provides the plunger stop means access to the slide pin. A dial indicator means is operatively connected within the dial mount and having a movable plunger extending downward and housed within a spring member which abuts the plunger stop means.

Abstract:

A device for measuring length and vertical clearance of engine connecting rods comprising a base which is attached to an upstanding member in a hinged fashion. A vertical guide slot of substantial length is disposed within the upstanding member along a longitudinal center axis and distal to the base. A wrist pin mandrel comprising a guide slot receiving member is disposed on the upstanding member such that said guide slot receiving member is engaged in the vertical guide slot. Positioned at the top of the upstanding member is a dial indicator within a mount. A plunger projecting downward from said dial indicator rests upon the top of the mandrel's guide slot receiving member. Proximally to the base of the measuring surface is a standard mount which engages a standard. The standard is vertically slidable and adapted to be locked at adjusted elevations within said mount. A pair of self-centering pins extend perpendicularly from the measuring surface which are offset one to each side of the standard equal distance and on a horizontal line above the mount.
