Agricultural engineering. 534 AGRICULTURAL ENGINEERING The Sheringham valve makes a satisfactory inlet. This is arranged by hinging the window at the bottom and allow- ing it to drop inward at the top between cheeks or triangular- shaped side pieces. The air in striking the inclined window is thrown upward toward the ceiling and is not allowed to pass directly onto the animals which may be housed in the building. The fresh air is diffused through the room and the foul air passes out through suitable flues, not unlike those to be described later. Cowls or cupolas are used in connection with outlet flues and are designed in such a manner that the winds in blowing across them produce a suction or aspirating effect in the flues. Temperature System. The principle that heated air rises is the theory basis of the majority of the successful ventilating systems now in use. The King system, named after the designer, the late Professor F. H. King, uses this principle as well as the principle that foul air is heavier than pure air when both are at the same temperature, and tends to settle towards the floor. For this reason, the inlets in the King system discharge pure air near the ceiling and the out- let flues receive the air near the Fig. 322; Showing one method of ar- ranging trie outlet flues in the King sys- tem. The flues may be brought together to form a common Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Davidson, Jay Brownlee, 1880-1957.
