Scientific American Volume 03 Number 09 (August 1860) . ertainly does full justice to the fervor ofhis political career ; for, successful as the result has un-doubtedly proved, want of experience and consequentignorance of the risk could alone have induced so boldan experiment; and we are rather led to wonder at thanto admire a structure which, as regards its proportionsand the small quantity of material employed in its con-struction, will probably remain unrivaled. i^ Hi — FLATTERYS IMPROVED FAUCET. This is a beautiful invention and it is just one ofthose little things that are always the best to make moneyout of. The water enters at A, and is discharged at B Thevalve, C, fits into its seat above, and is connected by itsstem, c, with the flexible india-rubber diaphragm, D, towhich it is secured by the screw, d. The faucet is closedby the pressure of the water against the valve, and it isopened by turning the thumb-screw, G, inward so as topress the valve downward away from its seat. As the valve is held up against its seat merely by the. pressure of the incoming water, as soon as this pressureceases, the valve falls down away from its seat, permit-ting a back flow outward, freely through the cock.This property adapts this faucet to many situations inwhich it is very valuable. For instance, a light boilerwhich is above the altitude at which water will be sup-ported in it by the pressure of the atmosphere, will be saved from collapsing on the withdrawing of the water, by having one of these faucets inserted in it, as a supplycock. As soon as the pressure from the outside becomesless than that from the inside, the valve will open andsupply the boiler with air. Again, in cases where thewater is drawn from the pipes of a building, to preventthem from bursting in cold nights, if these faucets areused as draw-cocks throughout the building, the empty-ing of the pipes may be effected by a single valve andspigot in the lower part of the building, without any at-tention to t
