Ajax announces a new line of prepackaged natural gas engine driven integral compressors. Each package is specifically designed for the California market and areas with similar climate requirements. Known as the 'California Specials', four compressors ranging from 42 to 115 horsepower are included in the line. The packages are based on a ten-year Ajax study of the specific needs of California compressor operators. All of the packages are completely furnished with accessories, piped, and ready to install on start-up location.

Except for the smallest Ajax model, the C-42 'California Specials' are equipped with overhead hydraulically driven coolers. These coolers can handle wide variations in cooling requirements due to changes in pressure conditions and ambients. The coolers are unitized with oversized water sections, high capacity high pressure gas sections, and a hydraulic oil section. Gas sections are designed for 10°F approach, after-cooling to ambient. For the C-42, Ajax uses a combination of an oversized radiator and a vertical discharge gas cooler. All packages are designed to provide cooling without regard to prevailing winds.

The other accessories of the special Ajax compressors are similarly designed to meet the same full range of California operating conditions. Piping, scrubbers, and cooler sections are engineered to exceed extrement pressure ratings.

The Ajax 'California' compressor cylinder is a well depletion type, two stage, single acting cylinder with one set of pressure packing. The cylinder is a high working pressure cylinder with overly adequate displacement and working pressure. This is provided so that the Ajax 'California Special' units can operate fully loaded (both single and two stage) throughout a wide range of expected suction and discharge pressures. . . without costly major shutdowns for conversion or modification.

Ajax uses its time proven slow-speed continuous heavy duty two-cycle engine as the integral prime mover for the 'California Special'. Power-end and compression cylinder are linked together by a balanced opposed crankshaft common to both engine and compressor, a concept pioneered by Ajax many years ago.

As a result of this feature, balance and weight distribution of each 'California Special' package is such that an unusually broad range of foundation and soil conditions are easily accomodated. Units are rated well below maximum for continuous duty.

Ajax Iron Works is a major operating division of Cooper Industries. Ajax has been a leader in the design and manufacture of specialized oilfield machinery for over ninety years. The company is well kr.own for its engineering conservatism.

Ajax compressors in California are sold and serviced by the Bovaird Supply, Mid-Continent Supply, and National Supply Companies, all noted for worldwide oilfield machinery distribution and service.

NEWS ITEM

We thought it would be a good idea to notify you that there is a small but active group of antique farm equipment collectors, ('The Ft. Allen Antique Farm Equipment Association') in the Greens-burg, Pennsylvania area. Since we have never made a big effort to publicize our group, we thought that there might be some of your readers in our area who would like to get together with other collectors but who do not know about our club. We meet on the third Tuesday of every month except Dec, Jan., and Feb. Anyone who thinks he might be interested may contact Melvin Bailey, R.D. 1, New Stanton, Pa. (834-7490) or Howard Wagenblast, R.D. 4, Greensburg, Pa. (668-7837) for more information.

At last count, the equipment owned by the club or members was: 6 steam engines, 1 oil pull, 2 threshers, 1 hand-tie wire baler, 3 shingle mills, 1 baker fan, 2 binders, about a dozen tractors, and approximately 30 hit - or - miss engines (along with some other miscellaneous items.)

Our annual show is held at the Harrold Community Fair (free) near Greensburg in August. Although a small show, we have the usual steam traction engines, tractors, and engines. Also, we demonstrate threshing, baling, shingle sawing, grain grinding, etc. Anyone who has equipment they would like to exhibit at our show is welcome to do so--just contact either of the fellows mentioned above.
