Fig. 21 is shown for the purpose of illustrating the English type ofsingle or straight line compressor. The machine shown is known asSchrams patent. A single cast iron bed plate is used, thus making themachine self-contained, and the fly wheels crosshead and connecting rod COMPRESSED AIR PRODUCTION. 49. FIO. 21. are placed on the bed, the steam cylinder being located between theseparts and the air cylinder. This construction brings the steam and aircylinders close together, but the machine is not as compact or as simpleas the direct acting compressor of the American type. Another form of European compressor on the straight line plan isshown in Fig. 22. This machine is made by Messrs. Burkhardt & Co.,
