Abstract
731,143. Variable-speed gear. LINDHOLM, N. G. H., JUSELIUS, S. O., and BERGQVIST, A. T. Nov. 23, 1953, No. 32432/53. Class 80 (2). A variable-speed reducing gear, which functions by disconnecting the driving and driven members 1, 8 for a variable fraction of each revolution, comprises a clutch-pawl 3, pivoted on an externally-toothed ring 2, driven by the input pinion 1, the pawl 3 being biased by a spring 7 for the forward edge of its semi-circular cross-section to engage drivingly the outer periphery of the output wheel 8, until an arm 4 of the pawl 3 strikes an adjustable stop 9, whereupon the pawl is rocked out of engagement and held by a latch 5 snapping over a pin 11 on the arm 4, until released forre-engagement at a later point by the latch 5 striking a fixed or adjustable stop 12. The stop 9 is carried on a calibrated scale-plate 13 which may be turned manually or electrically to adjust the idle travel and hence the speed-ratio. The gear may be used in apparatus for indicating deviations from average car speed or fluid flow, for marking errors in the course of ships, and for taximeters.
