# No. 450 (Brown 1868): "Ordinary force pump, with two valves. The cylinder is above water, and is fitted with solid piston; one valve
# closes outlet-pipe, and other closes suction-pipe. When piston is rising suction-valve is open, and water rushes into cylinder,
# outlet-valve being closed. On descent of piston suction-valve closes, and water is forced up through outlet-valve to any distance or
# elevation."
# Model (cm, gravity on, Brown's view from in front, the pump cut away in half section). The handle turns on the top of a swinging link
# from a lug on the barrel and is pinned to the piston-rod a short way along, so the rod rises and falls straight; the hand swings the
# handle (the only drive). The solid piston works in an open barrel. A flap hinged at one edge closes the suction hole in the barrel's
# foot; a passage from the foot leads to the outlet valve (a poppet) under the rising pipe. The water is lumped vessels
# (src/fluid/vessels.c): the barrel under the piston with the passage is a chamber the piston sweeps (28.2743 cm^2), the suction
# pipe is the well at -2000 Pa (its water ~20 cm down), and the rising pipe is an open tank (8.0425 cm^2) whose
# water rises with each down-stroke and runs over where the pipe is broken off. Both valves are real, the flap on a hinge and the poppet
# on a slide, shut by their weight and moved only by the pressures on their faces, passing water (orifice, cd 0.62) as far as they open.
