SAMUEL F. ALLEN, OF CHICAGO, ILLINOIS.
.IM'PROVED WATER-HEATER F'OR LOCOIMOTVIVE-ENGINES.
Specification forming part of Letters Patent- No. 29,452, dated August 7, 1860.
To all whom it may concern:
Be it known that I, SAMUEL F. ALLEN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Tater Heaters for Lo-. comotive-Engines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consists in constructing and arranging those parts which will be particularly described, substantially as set forth.
In the annexed drawings, Figure l is a longitudinal cross-section of theheater and the exhaust-pipes. Fig. 2 shows an end view of the boiler and side'view of the heater. Fig. 3 is aview'of the heater with one end removed. Fig. 4 is a View of the exhaust-pipes. Fig. 5 is a side elevation of the boiler and end view of the heater and a section of the float-valve.
In the figures, A represents the boiler and 13 the water-heater, said boiler and heat-erbe ing connected t( get-her by means'of the pipe A. The heaterl-S is provided internally with three chambersa water-chamber b and two steam-chambers a and 0. These chambers,
asseen, are annular, the water-chamber be- .in g situated between the two steam-chambers.
c c c 0 represent a series of water-tubes which connect with the water-chamber 19, passing across the inner steam-space, as elearlyshown in Fig. 2.
s s s are a series of stay-tubes which connect the two steam-chambers, being made to pass through the water-chamber.
as seen, and enter the heater B, conveying a portionof the exhaust-steam into the outer steam-chamber a.
m represents a pipe which connects the water-chamber in the heater with the valvecase H. In this VQIVQrCEtSG is a valve Lwhich is so constructed as to float when the case is filled with water, so that unless the case is almost empty the valve is out of its seat,and thus water may pass through. This valve-case connects with the force-pumps of the engine and the pumps connect by a pipe to the pipe B. (Seen in Figs. 2 and 5.
The exhaust-steam from the engine passes through the exhaust-pipes D D and a portion of it enters the heater, as represented in Fig. l. The Water-chamber I) being filled with water,itwill be seen that as the steam surrounds the said water-chamber itwill be condensed,
and when condensed it will pass out through the pipe on into the valve-case H and thence through the pumps, and will be returned from the pumps to the heater, entering the waterchamber through the pipe B. The pressure caused by the pumps forces the water from the heater or water-chamber into the boilers through pipe A. It'will be seen that-by this arrangement of the heater surrounded by steam and with steam on its inside the water within theheater will always be kept warm to be injected into the boilers. -\Vhen the water, leaves the valve-case II, so that the valve will not float, said valve sinks into its seat and prevents any escape of steam, as will are arranged and used'substantiallyas and for the purpose herein" specified.
3. In combination, the float-valve V, substantially as and for.thepurposespecified.
