Abstract
The record player has a turntable formed with an outer rim. A belt-pulley is mounted on the shaft of the turntable; another belt pulley is mounted on a pulley shaft parallel to but spaced from the turntable shaft. A belt connects the two pulleys. On this pulley shaft, a friction wheel is also mounted. The pulley shaft is mounted for movement in a plane normal to its elongation. A spring maintains the friction wheel in engagement with a motor output shaft via which the pulley shaft is driven. Normally, torque is indirectly transmitted to the turntable via the belt. However, all times when increased torque is temporarily required, the pulley shaft moves so that the friction wheel -- which remaining in contact with the motor output shaft -- engages the rim of the turntable to transmit additional torque directly to the same.
