This type is preferred when a direct connected engine is installed Having acquired the business formerly conducted under the name of the A. H. Barber Manufacturing Co., and having established a refrigerating machinery branch to which our Chicago factory is exclusively devoted, we are prepared to continue the manufacture of improved refrigerating machinery on a much more extensive scale than before. In describing the Barber Compressor, of which we are the sole manufacturers, we call special attention to the cylinder, the most important feature of the machine. It is cast with flanges on the sides, which allow it to set half way down in the bed and hold it perfectly rigid on the frame. The heads, as well as the cylinder, are cast of semi-steel and made in tongue and groove style, making it impossible for the packing to be blown out. The cylinder heads and valves are water-jacketed for the purpose of keeping them cool. Our patent suction and discharge valves are made in one piece of tool steel with a solid head. There are no threads or nuts on them which can be stripped, therefore there is no danger of the suction valve getting into the cylinder head and wrecking the machine, as is often the case in other styles of compressors. These valves are hardened and ground, so that it is not possible for them to pit and leak, as sometimes happens with soft metal valves. By taking out the valve cap nuts the valves are easily removed for inspection without disturbing any other part. In the center of the suction arm is placed a strainer to prevent pipe scales from getting into the cylinder or obstructing the valves. This can be easily removed by taking off the cap nut. The stuffing-box is lubricated by an oiling ring to which oil is supplied by a pipe from the lubricator above. This small pipe is also connected with the suction arm, which draws back any ammonia gas that may have escaped the first packing ring.
