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: This invention is a means for indicating the alignment or non-alignment of vehicle type frames. The device clips over a portion of the frame with an indicator arm terminating in an indicator finger which, if in alignment, will point toward a pre-determined location on the frame. If the frame is not in alignment, this is also readily apparent by the indicator being off the pre-determined location.

Abstract: An apparatus for sensing and measuring changes in inclination and providing a digital readout. By sensing pulse width changes rather than amplitude, the apparatus provides improved immunity to instability and environmental changes. A variable frequency scale factor oscillator allows choice of readout units. Any preset angle may be selected as a zero reference. The capability is provided to hold any reading displayed for any desired period of time. An overrange indicator is actuated when the linear range of the sensor has been exceeded. Digital output signals derived from the sensor are applied to gate an angle generator which is responsive to correction factor signals to adjust the digital count in accordance with stored offset data. The digital signal count is incremented or decremented in accordance with a signal representing the sign of inclination, derived from the sensor pulse widths and applied to gate the angle generator accordingly.

Abstract: A vehicle measuring instrument to measure a position-deviation of any selected vehicle reference point as when a person such as a car mechanic performs repair and maintenance of a car. With the well known vehicle measuring instrument of such type, an error caused by a deviation of the perpendicularity indicated by a pendulum member from the vertical direction of the vehicle due to an inclination of this vehicle has been detected and then a troublesome sequence of operations have been performed to compensate such error. According to the present invention, there is provided an angle variable portion by which an angle of each suspender with respect to a base frame can vary under an effect of this base frame's own weight in response to an inclination of the vehicle so that a reference portion is automatically displaced so as to respond to the deviation of the pendulum member and thereby to compensate said error automatically.
