Abstract
A turntable brake mechanism comprises a brake shoe located beneath the turntable for motion between a raised position and a lowered position in response to raising and lowering a record lifting rod which passes through one of the slots in the turntable to transfer the record between the turntable and a set of record receiving pads positioned above the turntable. When raised, the brake shoe engages the underside of the turntable to oppose the rotation of the turntable. The brake shoe is spaced from the turntable, when retracted, to allow the turntable to rotate freely.
