1894 Description of 'air-compressing plant recently erected at the works of the Patent Compressed Air Carpet-Cleaning Company, Limited, York-road, King’s Cross, N., by Messrs. Arnold Goodwin and Son, engineers, Southwark, S.E., the whole of the machinery being designed, constructed, and erected by that firm. The engines are each capable of developing 200 indicated horse-power, their power being transmitted through suitable spur gearing to the compressors. The compressed air from these passes into a receiver, from which it is distributed to the carpet-cleaning machines in the factory. A distinctive feature of the plant is that the compressors work at half the speed of the engine, so as to keep down the temperature of the compressed air. This result might have been attained by using, as in some other installations, condensing apparatus; but it would have been necessary to double the volume so as to get the same working efficiency. Some interesting details are consequently involved, and these we shall describe in their order. The engine cylinders (Figs. 1 and 3) are each 22 in. in diameter by 42 in. stroke, designed to run at 60 revolutions per minute, or a piston speed of 420 ft. They are made of close-grained cast iron, and are cast in one with the valve chamber, the steam ports being 10 per cent, of the cylinder area. The cast-iron pistons are of hollow section, and are fitted with Messrs. Goodwin’s piston rings (St. John’s patent), ....'[1]
