Again, suppose a pairof… … circle and point c, Plate 9, and the arc of contact ^youldbe but 1.05 of tlie circular pitch. Now, one of the claimsmade for the involute tooth is that the distance betweenthe centers of the geare nmj be changed without changingthe velocity ratio; but in tliis latter case it cannot be donewithout…
