The steam from the high-prtssure cylin-der instead of exhausting up the chimney is thus discharged intothe receiver and low-pressure cylinder. The movement of thevalve ^4 causes the piston B to come in contact with the valve Cand thus closes it and shuts off steam from the passage A. Theengine then works compound. THE RICHMOND SYSTEM. Figs. 4, 5 ,Tnd 6 illustrate the chief features of construction ofthe •Richmond system. They are similar to the views of thePittsburgh engine. To work the Richmond engine simple, the (33:.
