AR:RCC:cew PISTON RING SIDE TAPER GAGE A gage for measuring the taper angle of each side face and/or the included angle of taper between the side faces of a tapered piston ring, in which an anvil is pivotally mounted with respect to a reference surface and is adapted to be seated against the side face of a piston ring resting on the reference surface. A dial indicator is coupled to the anvil and provides a direct reading in minutes of the angular position of the anvil, which corresponds to the angle of taper of the engaged ring side face with respect to the reference surface. - - - o - - - i |
