See diagram, Fig. 3- The Pittsburgh engine is the sameas the Mallet, a non-automatic, con-vertible compound, and empties theL. P. steam chest in changing fromsimple to compound, whereby the cylinder becomes lame for severalrevolutions, until the receiver pressureis restored to normal, which progressesgradually by gains of H. P. exhaustover that removed by the L. P. cylin-der, stroke by stroke. These condi-tions are illustrated in diagram Fig. 4. The Rhode Island compound is auto-matic in starting and convertible intosimple by means of letting live steaminto a chamber above the intercepting. Holds firebox sheets secure-ly together, and accommo-dates itself to the unequalexpansion of the plates. FLANNERY BOLTCOMPANY PITTSBURC, PI., U. S. 1. Suite 308, Trick Bldg. O. E. D.
