Abstract

351,408. Speed governors. ROBERTS, J. H. T., Dashwood House, Old Broad Street, London. March 17, 1930, No. 11909/30, divided on 343,350, and 4228/31, divided on 11909/30. [Class 57.] A gramophone adapted to be driven by an electric or spring motor at either of two constant angular speeds is provided with two governors 19, 20 which are connected by a rod 26 so that either governor may be caused to engage by means of a worm 23, 24 with a worm wheel 25 driven from the gramophone mechanism. If desired, one governor may be in permanent engagement with the worm wheel 25 and only the other governor, which is adapted for the lower speed, may be movable by the rod 26.
