# No. 460 (Brown 1868): Fairbairn’s bailing-scoop, for elevating water short distances. The scoop is connected by pitman to end of a lever or of a beam of single-acting engine. Distance of lift may be altered by placing end of rod in notches shown in figure.
# Model (cm, gravity on, Brown's view from in front, the trough's near side cut away). The lever (the engine's beam) is rocked
# 0.31 rad either way at 0.22 Hz (the only drive); its pitman, its end in one of the notches, raises and lowers the
# scoop, a wedge trough hinged on the left bank's edge, 44 deg. The scoop's water is a tank it carries (its weight on the
# trough where it lies, so the lever lifts it): while the trough's far lip is under the pond's surface the pond runs in over it until the
# level inside is the pond's, and while the trough falls toward the pivot the water runs out at its open end into the channel on the bank,
# which runs off over its weir. The pond is kept at its level by the stream feeding it.
