Figure 3 shows the arrangements for heating, storing, and mixing water in the basement. Water under direct street pressure is taken through a 1-inch trap and 2-inch service pipe to a 2-inch meter M, Fig. 1, from which it is delivered through pipe D to the 600 gallon galvanized-iron boiler B, and from it flows through the 4-inch circulation pipe E, and the 2-inch branches F F to the two Hitchings heaters A A, returning hot through the 4-inch circulation pipe G, and the 2-inch branches H H. The heaters are also connected to the hot-water radiators by the 1½ - inch flow pipe I and the return pipe J. Hot water is delivered from the boiler through the 2-inch pipe K, which, entering with the cold-water pipe N direct from the meter M, delivers to the 20-gallon galvanized-iron mixing chamber C, from which the water is delivered at any required constant temperature to the bath douches through the 2-inch pipe O and its 1½-inch branches P P P. Ordinarily valves a. b, d, and e, are closed and cold water enters at the bottom of the boiler B through pipe D, and hot water from the circulation pipe G enters through branch S, but if hot water is needed quickly, as early in the morning, before all that in the boiler B is heated, valve E is opened so that the boiler is supplied most directly from the heaters. When the heaters A A are not required to heat water for the radiators, the thermal energy supplied to the boiler B will be so much increased that a means for cooling the water in the boiler has been provided - viz.,by means of the branch V that is taken from the cold supply pipe D and terminates in a perforated horizontal pipe 6 feet long that is near the top of the boiler B, inside of it. Ordinarily the valve a being open and b closed, this device is not in operation, but if a is closed and b opened the cold-water supply is distributed all over the top of the boiler and instantly mixes with and lowers the temperature of the hot water supplied through pipe K. The boiler can be emptied through the waste pipe X. W is a drip pipe to empty the rising lines. R is a cold water supply to the slopsinks and bowls and Q is a water-pressure gauge. T1, T2, T8, are special hot-water thermometers made by the Hohman & Maurer Thermometer Company, of Pea-body, Mass. Thermometer T indicates the temperature of the hot water in the center of the hot-water tank, Tt indicates the temperature of the mixing of hot and cold water, T8 indicates the temperature of the water as supplied to the douches, and Ts indicates temperature of hot water as coming from top of hot-water tank.

The mixing is adjusted by valves//, which are so sensitive that a very slight movement is shown on the scale of the thermometer T1( by which the baths may be regulated, though thermometer T2 is usually consulted after the valves are approximately set; h is a safety valve. Pipes N and K were at first connected to the heating chamber at j j, but have been found to operate more satisfactorily arranged as shown with a common delivery L. Y is a smoke flue and Z is the high angle-iron frame supporting the boiler.

Figure 4 shows the construction and arrangement of a bath compartment. C is the corridor from the wooden screen doors D D, etc., open into a dressing-room A, about 4½ x4½ feet, which is separated by half-partition E from the bath place B, which is about 4½ x4 feet wide, with a depressed basin F about 8 inches deep. Water at about a temperature of 100 degrees is supplied through the 1½-inch distribution pipe G, with ¾-inch branches H H, to the copper douches I I, etc., which are above the bather's reach and set at an inclination to deliver water upon his neck and body, but not upon his head unless he especially presents it. The douche is governed by a self-closing bibb, which is opened by a lever I and chain K, whose ring may be pulled down to hook I and secured there, so as to hold the valve open and leave both the bather's hands free. Each bath compartment is provided with a stool P, seat O, mirror M, gas burner N, comb, soap tray S, and with shelf, clothes hooks, and a bolt on the door D. The brass strainer or waste pipe W is designed to be not quite large enough to carry off the water as fast as it is received from the douche I, so that it rises in the basin F until it overflows through R, thus keeping a few inches in the basin F to cover the bather's feet.

Figure 5 shows the floor drainer (Figs. 1 and 2). It is essentially a brass bowl B, nearly hemispherical, and about 9 inches in diameter, which receives the house flushings, etc., and delivers through pipe P, which discharges freely into a trapped waste pipe. The flange F is set flush with the surface of the floor, which is graded to this point, and when the valve V is fully shut, the cover C can be entirely closed and rest in its seat, offering no obstruction above the floor surface. If however the valve is raised at all, its stem S will project above the bottom A of the cover seat, and interfere as shown with the cover, thus compelling the attendant to screw it down and close it tightly in order to remove the floor obstruction. The valve stem S screws up and down in block G, -which is removable from ring D, cast with legs E E solid to the bowl B. The solid head H of stem S lifts valve box I by its cap J, through which the screw passes loosely. K is a rubber gasket, L a brass washer, M a nut. This floor drainer was designed by Oliver Barret, New York, who has placed it upon the market.
