Floor kitchens and certain industrial proc ess rooms has been a standard prac tice. Such pans have proved to be an adequate and economical insur ance against damage to materials stored below as well as to structures and decorations. A recent article in this publication described a large lead pan in a plating works in Detroit. Two large lead floor pans have been installed recently in New York's Grand Central District within one hundred yards of each other. One of them under part of the kitchen and the dishwashing room of Thompson's Restaurant in the Grand Central Ter minal building was placed earlv in Mav of this year. The other which is under the soda fountain in the W halen Drug Store at the corner of 42nd St. and \ anderbilt Ave. has just been completed. These two lead pans are similar to Completed lead pan under restaurant kitchen. .\ore bleeders in place and lead sleeies around penetrating pipes. Asphalt paint uill be applied before slab is laid. drains with clamping rings for the lead and ample weep holes are in stalled at suitable intervals and in verted V or l bleeders leading to the drains are tack welded to the lead pan. Before the finish floor slab is ap plied the entire surface of the lead is coated with a heavy asphalt paint to protect it until the cement is thor oughly cured. There are conditions in all tvpes of buildings which create potential leakage hazards. Kitchens, toilet rooms, air conditioning rooms, la boratories and any other areas where water is used in quantity should all be carefully considered as possible sources of trouble which can be averted by use of a properly installed lead floor pan. Sheet lead by reason of its easy adaptability to the shape of its location is ideal for this purpose. Lead Cooling Coils In Anodizing Tank To Handle Direct Expansion Refrigeration N interesting and unusual ap- carried up over the top of the tank At plication of lead pipe coils is where it is welded to a steel pipe shown in the accompanying photonipple for connection to the suction graphs.

The outlet end of each coil is con nected to a 3-in. lead pipe suction header closed at the bottom. Ex tending down inside the header to within 3 in. of the bottom is a H o-in. lead suction pipe bushed and welded at the top of the header. This pipe is as the cathode of the anodizing cir cuit. In addition a ventilating hood of 3 16 in. lead will be built over the tank to dispose of acid vapors gen erated by the process. The tank is 3 ft. 10 in. wide by 9 ft. 1 in. long by 3 ft. 6 in. deep. It was designed and installed by Reli ance Refrigerating Machine Co. of Chicago. All of the lead work, both tank lining and coil, is constructed of tellurium lead. All seams in the lining are welded and the coil sup ports are welded to the coil at each intersection.

Agitation will be provided by three perforated lead aeration pipes. The use of lead pipe for an expan sion chamber for a refrigerant gas is unusual but perfectly feasible if the suction pressure is not excessive. In the case of freon operating at 40 to 50CF the suction pressure will probably not exceed 50 lb. per sq. in., which is the allowable working pressure for Class 50 lead pipe as desicnated in Federal Specification -P-325.

Its expanded application will materially speed construction. Lead Pipe For Water Service Under Heavily Traveled Streets LTHOUGH its use is not man obstructions and formed into an in A datory, the installation of lead tegral expansion loop or gooseneck water service pipe is standard pracw ithout the use of fittings which are tice in New York City. A large ma jority of the service pipes in the cityare of lead as was demonstrated re cently- during the replacement of a water main in East 39th Street which was reported in the Januarv-February issue of LEAD.

In addition to being durable and resistant to corrosion, lead pipe has other qualities which make it desir able for use under city streets. It has flexibility which makes it adapt able to installation in one piece with out extending the trench across the entire street. It can be bent around potential leak hazards. Lead is not responsive to vibration and therefore it is less likely to transmit sound than are other metals. Being a rela tively poor conductor of electricity lead is only slightly susceptible to electrolysis. The pictures show the installation D-- LIA25911 From the main, under the street, offset down two feet and into the basement, this lead service pipe is in one piece. in progress of a 2-in. lead water ser vice without interruption of traffic, in this case the pipe was drawn through the space previously occu pied by a smaller service pipe. In addition to the gooseneck which will be formed at the main end of this pipe it will offset down about 24 in. before it enters the basement. Both the durability of lead itself and the absence of joints and fittings will contribute to the long life which ran be expected from the service pipe. Manv cities throughout the l nited States require the use of lead service pipe with the result that both prop erty owners and water supply agen cies benefit from lead's convenience and durability. New York's Third Avenue El. Gets A New Coat Of Red Lead E\S Yorkers during the past ditional structures and stations in the N summer have perhaps been Bronx and Queens. The procedure startled on turning into Third Avinec ludes wire brushing and priming nue and beholding what seemed to with red lead paint of all of the iron be miles of brilliant red elevated and steel work including hand rails structure. The famous old "3rd Ave. and all exposed bolts and washers El. ' has been receiving its first re painting in manv years. Maintenance work which had to be put off during the war has been resumed and under Columns newly coated with red lead, upper structure partly unpointed, partly finish coated. taken in large units in an effort to reduce the large gaps in the schedule. The Yew ^ ork Cit \ Board of Transportation in common with olive' administrative units of the cilv gov eminent, including that responsibl- for the maintenance of the great bridges, makes the use of a red lead priming coat regular practice in maintenance painting procedure. That this practice is good is demon strated by the sound condition of the many steel structures maintained by the city on which red lead has been used constantly. The work undertaken this sum mer was extensive. It included the 3rd Ave. structure from 44th to 105th Streets, the South Ferry Sta tion, 9th St.. 125th St. and 129th St. stations in Manhattan as well as ad securing ties and other wood struc tures. This is followed after a suit able drying period by a coat of light grev-green white lead-base paint. The result in addition to preservation of the metal work is a noticeable brightening up of 3rd Ave. Future plans call for the eventual removal of the 3rd Ave. El. but until other means of transportation fur l Continued on paee 8 > bleu along 3rd A i e.. sacral shade lighter as a result ot the repamtine mmauum LI425912 f ^XPortfpl10 of i ; American Iv No. 39 Geneva An Early Settlement In Central New York N 1828 one James Stewart, a gentle I man from Scotland, passed through Geneva, New York, on the first leg of a journey which he later docu mented in a book "Three Years in North America."
