Abstract
The object of this invention is to provide an improved drive control mechanism for the turntable of a phonograph. The drive control mechanism comprises a control lever successively movable in one direction from an off position to a 331/3 rpm (revolutions per minute) position or a 45 rpm position for record playing, and then in the reverse direction to its off position. A drive shaft has first and second drive portions of different diameter. A rotatable puck is interposed between the drive portions and turntable for selectively drivingly connecting the drive portions to the turntable. A linkage-means couples the control lever to the puck so that when the lever is moved between the off, 331/3 rpm and 45 rpm positions, the puck is selectively moved (1) out of engagement with the drive portions and turntable, (2) into engagement with the first drive portion and turntable, and (3) into engagement with the second drive portion and turntable respectively.
