ABSTRACT:
A method and apparatus for checking toothed articles such as splines. A spline is rotatably supported in a cradle, and a pair of discs, one of which is axially moveable, the other of which is axially fixed, are brought into engagement with generally parallel and oppositely directed teeth of the spline. The discs are of the same hand and are rotated in unison causing rotation of the spline in the cradle. Relative movement of the discs is monitored to provide a succession of span measurements in order to provide information which can be used to sort splines according to their deviation from designed dimensions.
