Abstract
A railroad car-warning bell is centrally mounted on the hub of a wheel. Three opposed cylinder housings each contain a reciprocating ball which hits an end hammer to sound the bell when the wheel turns slowly up to speeds of nominally 15 mph. At higher speeds the balls are held against the end hammers, thereby automatically shutting off the bell to prevent noise pollution. The preferred embodiment has a single cylinder mounted along a diameter of the ringing bell. Three steel balls oscillate back and forth hitting a hammer at each end of the cylinder. A dampener may be used to adjust the ring of the bell.
