Abstract: An apparatus for measuring a metal terminal includes a crimping unit which crimps core wire crimping piece portions to a core wire of a sheathed electric wire to form a core wire crimping portion and crimps sheath crimping piece portions to a sheath portion of the sheathed electric wire to form a sheath crimping portion, a gripping member which grips the core wire crimping portion in a direction perpendicular to an extending direction of a base plate portion of the metal terminal, and a measuring unit which measures a dimension of the core wire crimping portion and a dimension of the sheath crimping portion. A height of the sheath crimping portion is measured in a direction intersecting with or parallel to the direction of gripping of the core wire crimping portion in a state that the core wire crimping portion is gripped in a direction perpendicular to an extending direction of the base plate portion.

Abstract: A device for measuring the diameter and circumference of a flexible circular object which includes two movable gauge pieces. The flexible circular object to be measured is place between the two gauge pieces and compressed thus forcing the object to be measured to conform to the shape of the gauge. The distance separating the gauge pieces is measured and is compared to the gap produced by a reference. The length of separation is converted to diameter and circumference measurements by appropriate means.

Abstract: An apparatus for measuring crimp height between crimped opposite sides of a terminal which has been crimped to an element is provided. The apparatus is particularly useful for measuring the crimp height of a terminal when one or more of the crimped opposite sides has a surface profile that is non-planar, or when a soft insulation sleeve is present on the terminal in the crimp area. The apparatus includes a pair of opposed probe members which are relatively movable between open and closed positions. In the open position the probe members are spaced apart- In the closed position the probe members are biased against the crimped opposite sides by springs. The probe members are specially configured to match the surface profiles of the crimped opposite sides.

Abstract: An apparatus for gauging the height and outer diameter of a collar in a heat exchanger plate fin. The apparatus comprises a vertically displaceable carriage overhanging a base on which a plate fin can be mounted for measurement. On the carriage are mounted two displacement indicators, in the preferred embodiment electrical linear gauges. One indicator is oriented so that its indicator probe measures vertical displacement and, through the configuration of the apparatus, produces an output that can be translated to a measure of the height of the fin collar. The other indicator is oriented so that its indicator probe measures horizontal displacement. The independent but concerted positioning of two measuring blades to contact diametrically opposite points on the fin collar is resolved into an output from the horizontal indicator that can be translated into a measure of the outer diameter of the fin collar. In a preferred embodiment, the outputs of the two indicators are read on electrical digital readouts.
