Abstract
A gear testing apparatus has a probe or feeler biassed into engagement with a gear tooth flank for measurement of the flank. To lift the feeler from the tooth flank and/or to displace it to a further setting in which it can be used to measure an oppositely facing flank a mechanism is provided that requires only a momentary power input to effect the lifting or displacement. The apparatus is arranged to retain the feeler in its new setting when lifting or displacement has occurred and after said power input has been discontinued.
