Abstract

216,465. Victorsohn, M. April 23, 1923. Turntables. - The turntable spindle 27 is adjustably mounted on ball-bearings, a collar 67 being fixed near the upper end of the spindle and supporting a set of balls 68 which are retained by a race 69, while the lower end of the spindle rests upon a thrust bearing comprising a set-screw 77 and an interposed ball 76. The set-screw, which is provided with a lock-nut 78 engages in a socket 71, which also forms a race for a set of balls 74 surrounding the spindle. The screw 77 enables axial adjustment of the spindle to be made, to take up wear on the bearings.
