1931 and 1937 Car Builders Cyclopedia owners, do these cover air conditioning

I am looking for information on Ice Activated Air Conditioning systems, photos in particular.  The 1940 Car Builders Cyclopedia 15th edition very briefly mentions the ice systems by B. F. Sturtevant.  The freon systems were becoming more common by 1940.  The 1931 and/or 1937 editions may have a more detailed discussion of the ice activated systems than the 1940 edition.  My attempts to obtain copies from the interlibrary loan system were not successful because these are considered Reference Books.  But, before I start the process of searching the Library of Congress for copies, it would be good to know if those editions covered the subject with photos.

    Mr. Dave. The C&O Historical Society is offering an HO scale Pullman Mechanical (PM) Air Conditioning System that first became available in 1932. Complete information on the A/C compressor is available at: http://chessieshop.com/index.php?main_p ... ts_id=3473. I know you were looking for Ice Activated A/C systems, but I thought you might be interested in this one too.
    For those wanting to use mechanical A/C on their models, I went through the New Haven RR official diagrams published in NHRTIA's Passenger Car Diagram Book: Revised Edition (1975) and read that virtually every passenger car that used mechanical A/C systems were equipped with the "Safety" Company's 5 or 7 ton capacity mechanical system with the single or double evaporator unit, ductless type, mounted in the deck in the center of the car, operated by "Safety" compressor-condenser unit. I tried to find pictures of the "Safety" Company's compressor-condenser unit to compare with the Pullman Mechanical A/C System compressor being offered, however I was unsuccessful. This included a Google search using the above link but replacing ice activated with mechanical. The only A/C compressor unit I found was a Waukasha Air Conditioning System unit on Oregon Pacific RR car 128. The Waukasha A/C System compressor has a square vent area on the left of the mechanical box, and doesn't match the Pullman Mechanical A/C System compressor offered. I really cannot say if this A/C compressor would be appropriate on any of the New Haven passenger cars unless you find one that was specifically equipped with a Pullman Mechanical A/C System. Just a caveat emptor.

If we go by the information on page 899 of the 1940 Car Builders' Cyclopedia, the motor, compressor and condenser are in an enclosure 66.5 inches long, 40.8 inches wide and 27.6 inches high under the floor of the car.  There are photos and and drawings on that page. This unit supplies chilled water to the B. F. Sturtevant fan and coiling coil in the center of the car.  This is distinguished by the louvered air intake on both sides of the clearstory exterior on both mechanical and ice activated systems.  If you want further information, contact me at dvvarholy@sbcglobal.net.  I have some catalog pages from B.F. Sturtevant also.

The C&O Historical Society AC compressor is part of a first generation Pullman Mechanical Air Conditioning System that was installed in 1933, on about 60 cars used on the C&O.   The Pullman Project Database supports the data that the C&O cars were the majority of the installations.  This equipment was only installed on cars during the 1932-1934 time period.

The Pullman Mechanical Air Conditioning equipment used on the cars used on the New Haven was installed on Pullman cars after 1934 and represents a second generation system.  This equipment is offered by Precision Scale Company, New England Rail Services, and Bethlehem Car Works.

I promise to drop the air conditioning subject after this entry.  I forgot that Trainlife.com has several model railroading magazines that you can view online including Railmodel Journal.  Railmodel Journal had a four part series on heavyweight passenger car air conditioning including comments on the articles, provided by Don Valentine from New England Rail Services.  So, if anyone is interested in the history of railway air conditioning, the following Railmodel Journal issues will be of interest: October 1997, Part 1; February 1998, Part 2; and March 1998, Part 4 and Part 5.  There are plenty of drawings and photos to support the articles, including the C&O compressor.
