When a sin;;li' engine is to be used it may be placed between the generator and receiver (tigs. 1 and 2). the sleam from tig. I entering the cylinder by ilie steam pipe N. and after propelling the piston it is conducted from the eduction pipe through the sleam pipe// into the receiver, where it heats the water in this vessel, becomes of less expansive force in consequence, and is passed into the atmosphere through the fregulating valve 11, tig. 'i. When two sleam engines or cylinders arc to be used the steam for the secoml engme is taken from the receiver and passed through its cylinder by means of the sleam pipe A, which is only used where two engines are in use, and is afterwards wasted through an air pump and condenser attached to the second engine. This system of supplying cylinders with the same steam can be ex- to more than two cylinders when it may be required. The second improvement is for the formation of a boiler having two or more fuinaees. with the flues carried by a curved flue into a horizontal flue stretching across the boiler at right angles to the furnaces, and then carried up into a single chimney, as shown in the drawings annexed to the specifi- cation.
