specially constructed Loomis Manning filter, tested 

 to 500 pounds. Leaving this it flows to the ice water 

 cooling tanks, and thence to the ice water circulating 

 pumps which force it up to the 39th floor through 

 four risers, and return it through four circulating 

 lines back to the cooling tanks. The ice water is 

 thus circulated continuously and its volume replen- 

 ished from the 39th-story tank. The ice water piping 

 is covered with a cork insulation 1 inches thick. 



All cold and ice water piping subjected to ex- 

 cessive pressure, on account of the great height of the 

 building, is made of extra strong galvanized wrought 

 iron pipe. On the plumbing section drawing are in- 

 dicated the large soils, wastes and vents which had to 

 be installed, and the method of connecting them to- 

 gether at the top. 



The contract included the furnishing and setting 

 of about 750 new plumbing fixtures, with their ac- 

 cessories. The method of concealing all piping 

 about the office basins, and making the valves 

 accessible by means of metal doors placed under the 

 fixtures, as shown in the cut of the fixtures on page 

 60, is of particular interest. 



PLUMBING, BOURNE BUILDING 

 ADDITION 



THE plumbing work in connection with the Bourne 

 Building Addition is a splendid example of modern 

 up-to-date plumbing. Great care has been taken in 

 the selection of the various materials and fixtures and 

 mode of installing them. All underground piping is 

 of extra heavy cast iron, each area line, leader and 

 floor drain is properly trapped, each trap having 

 cleanout screws of extra heavy cast brass accessibly 

 placed. All leader, soil and vent lines above the 

 basement and grade are of extra strong galvanized 

 iron pipe, and supported by clamp hangers of the 

 most recent pattern. The fresh air for the sewerage 

 system is supplied by a 6-inch " Perfect " fresh air in- 

 take, extending to the open air. The floor drains are 

 of bronze, with removable strainers. The area and 

 floor drains are connected to a "sump" pit, which is 

 automatically emptied by a motor-driven submerged 

 pump specially built for the purpose. 



The fire protection for the building is most 

 thorough and complete. It consists of 6-inch extra 

 heavy galvanized standpipe, extending from a 

 Siamese connection 6 inches in diameter with two 

 3-inch outlets, Fire Department pattern, to the main 

 house tank system, and has at all times a direct pres- 

 sure of 300 pounds to the square inch. This standpipe 

 is also cross connected to the fire and house pumps 

 in the basement. On each floor there is an equip- 

 ment consisting of a hose reel containing 100 feet of 

 SJ-inch best linen hose controlled by a 2^-inch red 

 metal fire valve, with nozzle, etc., complete. This 

 part of the work has the approval of the Fire Depart- 

 ment and Board of Fire Underwriters of New York 

 City. 



Each stack of fixtures is supplied with hot and 

 cold water and a return circulation. The cold water 

 supplies are of extra strong galvanized iron pipe and 

 the hot water of soft annealed brass pipe. Where 

 the least danger from frost or atmospheric con- 

 densation exists the supply pipes are covered in the 

 most approved manner, and are canvased, ringed 

 and painted. 



The fixtures are all class "A" and as selected 

 by the architect. There were installed 9 water- 

 closets, 107 basins and 1 shower bath. The words 

 " J. L. Mott Iron Works" stamped on each of these 

 fixtures guarantee them to be of the highest quality 

 and efficiency. 



The closets are of the siphon-jet type with " Sim- 

 plex" valves. The urinals are the "Metropolitan" 

 with "Integral" traps and "Presto" push-button 

 flush valves, the basins principally of the " Claremont" 

 pattern with integral back and "Hygeia" wastes. 

 The slop sinks are of "Imperial" porcelain pro- 

 tected by pail guards. All metal work in connection 

 with these fixtures is of red metal, heavily nickel 

 plated. 



Sufficient gas-fitting has been supplied to light 

 the basement toilet rooms and the corridors in the 

 event of failure of the electric plant. 



The work has been executed and installed in 

 the most thorough and workmanlike manner, under 

 the personal supervision of the plumbing contractor, 

 Chas. H. Darmstadt, No. 352 West Forty-third 

 Street, New York City.
