ABSTRACT:
A stylus is attached to one end of a stylus holder which is mounted on a trunnion and adapted to rotate about a first axis. Attached to the trunnion is means for pivoting the trunnion about a second axis transverse to the first axis, in order to position the tip of the stylus adjacent a surface of a rotating scaife. A stream of fluid is directed against a vane attached to the stylus holder in a manner such that the fluid causes the holder to rotate about the trunnion, thereby changing the rotational position of the stylus without significantly altering the force of the stylus against the scaife.
