A continuous distributor consisting of a steel open-topped box filled with
stone dust. Resting on the surface of the stone dust is a steel plate 1/4
in (0.64 cm) in thickness fitting loosely into the box and perforated with
holes 3/16 in (0.48 cm) in diameter. The plate is connected by a series of
chains and levers to a lever between the rails on either the loaded or
empty side of the roadway. Each tub passing along depresses the lever and
causes the steel plate to be lifted. A counterweight restores the track
lever to vertical and the plate falls, causing a puff of stone dust to be
ejected through each hole into the ventilating current. Thus stone dusting
keeps pace with output. Sinclair, 1
