The following is taken from the Sanitary Engineer of December 4, 1883:

Our illustration, Figure 134, shows the novel arrangement of high and low pressure boilers in the residence of Mr. Sidney Webster, at 245 East Seventeenth Street, New York. The problem in this case was to utilize the limited space between the door and window for the kitchen-range and boiler paraphernalia. As the length of the space was not sufficient for the usual order of "double boiler" (one within the other), the arrangement shown was devised in preference to placing the boilers at a distance from the water-backs, whereby the question of circulation between the backs and the boilers might be jeopardized by carrying the flow-pipes above windows and door, and the return-pipes underneath the floor.

Little can be said of the arrangement that is not apparent to the plumber in our very accurate drawing of the kitchen, but of the materials used and their sizes we will say a few words. The boilers are 48-ounce copper, each being forty-two inches long by twenty-one inches in diameter. They are encircled by copper bands, which secure them to vertical hangers, which enter the floor-beams, with large iron washers on top. The boiler A Figure 135, is the low-pressure or "Croton" boiler, the other boiler (B) being the tank-boiler. The "Croton" or street-pressure pipe comes through the floor at the right of the range, and is supplied with a check-valve at a in the diagram, thence runs behind the boilers, as shown by the dotted lines, connecting directly with the low-pressure boiler at a, and with the high-pressure boiler through the pipe and check-valve s, which connects with the tank or high-pressure supply-pipe b close to where it enters its boiler. The object of the connection s, which is well known to plumbers, is to provide an auxiliary supply to the high-pressure boiler should the tank in the top of the house be empty through any cause, at which time the low-pressure will press through the check-valve and supply the boiler.

Two water-backs are used, the pipes e forming the primary circulation for the low-pressure boiler, and the pipes f performing the same function for the other. The pipe C is the warm low-pressure supply, which goes to the lower stories - first and the basement - the pipe C' being the return circulation from the same. The pipe d is the warm high-pressure pipe supplying the upper stories, d' being the return circulation for the same. The pipe used is bright seamless brass, with cast-brass elbows and fittings.

Behind the boiler A is a ventilator-register of one and one-half square feet area, and opening into a chimney parallel with the rangechimney. The chimney-breast, which forms the background to the range and boilers, is of white glazed brick, quoined with glazed chocolate-colored bricks. The floor is of encaustic tiles in warm colors, and, taken altogether, the kitchen is very complete.
