"From on pan suspend a hollow cylinder of metal t, and below that a solid cylinder a of the same size as the hollow part of the upper cylinder. Put two weights in the other scale pan until they sxactly balance the two cylinders. If a be immersed in water, te scale pan containing the weights will descend, showing that a has lost some of its weight. Now fill t with water, and the volume of water that can be poured into t will equal that displaced by a. The scale pan that contains the weights will gradually rise until t is filled, when the scales will balance again." —Hallock 1905

"As the piston ascends, as shown in the left-hand figure, the pressure of the atmosphere forces the water up the suction pipe P; the water opens the suction valve V and flows into the pump cylinder. When the piston moves down, as shown in the right-hand figure, the suction valve is closed and the delivery valve V' opened. The water in the pump cylinder is now forced up the delivery pipe P'." —Hallock 1905

"A double-acting pump of the piston pattern is shown [here]. Such a pump has two sets of suction valves and delivery valves, one set for each side of the piston. With the piston moving in the direction of the arrow, the pressure of the atmosphere forces the water up the suction pipe P into the left-hand end of the pump cylinder, the left-hand suction valve opens and the left-hand delivery valve is closed...The water now flows up the delivery pipe P'." —Hallock 1905

"For many purposes compressed air is preferable to steam or other gas for use as a motive power. In such cases air compressors are used to compress air. These are made in many forms, but the most common one is to place a cylinder, called the air cylinder, in front of the crosshead of a steam engine, so that the piston of the air cylinder can be driven by attaching its piston rod to the crosshead in a manner similar to a steam pump." —Hallock 1905
