  • the outer surface of the tubular member 11 is spaced from the central portion of the surface of groove 17 directed toward spindle 6 by a distancelwhich is less than the thickness of the lock pins 18 so that these lock pins are urged by the springs 19 into wedging engagement with the tubular member 8 and tubular portion 16, and in this way the lock pins 18 prevent turning of member 11 in tubular portion 16 in either direction.
  • the spindle 6 is formed at approximately its right half, as viewed in Fig. 2, with an axial bore into which an elongated pin 21 extends, this pin 21 having a threaded portion of enlarged diameter threadedly engaging a threaded portion of the axial bore of the spindle 6, as shown in Fig. 2.
