The compressors of larger size arealso built with mechanically moved in-take valves of semi-rotary Corliss type,placed in the cylinder heads and drivenby gear from eccentrics on the mainshaft. These positively moved valvescombine exceptionally liberal area withshort ports and minimum clearance. The motion to drive these Corliss In-take Valves is taken from the steamcut-oflf valve stem or rocker arm of theopposite side of compressor. The airdischarge valves are of poppet type,cup shaped, pressed from high gradesteel and fitted with light tensionsprings. These valves also have re-movable seats and guides and are read-ily accessible for adjustment or cranks are of the disc pattern,made from the best quality of charcoaliron. The shafts and crank pins areforced to their places, the former beingkeyed and the latter riveted. Theintercooler, which is separate from thecompressor, and may be placed whereconvenience dictates, is a most im-portant feature. This consists of a. ing water between the air cylinder andthe cylinder head, thus excluding thepossibility of accident by water enter-ing the interior of cylinder should thegasket between cylinder and head be-come defective. These compressorsare manufactured with two forms of FRANKLIN AIR COMPRESSOR CLASS C. S. C. from high grade steel, having remov-able seats and guides easily renewedor repaired, and are thoroughly guardedfrom entering the cylinder. The valvestem and head are forged in one pieceand the valve seat is a part entirelyseparate from the cylinder head and steel shell containing a set of tubes, thetubes being fitted into the heads withprovision for expansion and contrac-tion. A constant circulation of coldwater is maintained through the tubesand the compressed air from the in-itial compressing cylinder enters the 33^ RAILWAY AND LOCOMOTIVE ENGINEERING July, 1907- intercoolcr on one side, and
