# No. 453 (Brown 1868): "Double lantern-bellows pump. As one bellows is distended by lever, air is rarefied within it, and water
# passes up suction-pipe to fill space; at same time other bellows is compressed, and expels its contents through discharge-pipe; valves
# working the same as in the ordinary force pump."
# Model (cm, gravity on, Brown's view from in front, cut in section). The lever turns on a fulcrum on the upright behind and is worked by
# hand at its right end (the only drive). A rod hinged on each bellows' top is pinned to the lever, the left one further out than the
# right, as Brown draws them. Each bellows is a lantern: 3 hoops and its top, each on a slide over the one below, with the
# leather between folded inward in pleats: two leaves hinged on the hoops and on each other at the crease. The leather's spring on each
# slide shares the stroke among the pleats. The base box is split by the riser: under each bellows a poppet on a hole in the floor lets
# water up from the suction channel, and a flap hung on the riser's wall lets it out into the riser. The water is lumped vessels
# (src/fluid/vessels.c): each bellows with its half of the base is a closed chamber its top sweeps (95.0332 cm^2; every pleat's
# slide carries the top, so each slide is a piston of that area). The suction channel and pipe from the well, and the riser, are full.
# The riser delivers 60 cm up, out of the picture, through a pipe with inertia. Every valve is moved only by its weight and the
# pressures on its faces.
