ABSTRACT:
An inertial phonograph device having a flywheel (50) carrying a record member (56) with a plurality of interleaved sound tracks pre-recorded to match the rundown speed of the flywheel (50). A constant predetermined rotational force is imparted to the flywheel (50) by means of a sector gear (82) selectively engaging a pinion (58) on the shaft (52) of the flywheel (50), the sector gear (82) being pivoted to its start position by the force of a spring (106). The sector gear (82) is pivoted against the force of the spring (106), out of engagement with the pinion (58), by means of a pull string (84) passing through a sector clutch (96), and, after engagement of the sector gear (82) with the pinion (58), rotation is restricted by a brake shoe (120) coacting with the flywheel (50) until the brake shoe (120) and sector gear (82) are released by the action of the pull string (84) and the sector clutch (96).
