WILLIAM O. FORD, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN SUPPLVING HEATED AIR T0 BOILER-FURNACES.
Specification forming partof Letters Patent N o. 1 70, [611, dated November 23,' 187i); application filed September 29, 1875.
To all whom. ift may concern:
Be it known that I, WILLIAM C. FORD, of Brooklyn, in the county of Kings and State of New York, 'have invented certain new and useful Improvementsin Steam-Boilers 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawing, making part of this specification, in which- Figure l is a vertical longitudinal section through an ordinary locomotive boiler, with my improvement applied thereto; Fig. 2, a horizontal longitudinal section through said boiler, showing the application of said invention and, Fig. 3, a transverse section through said boiler on the line wx, viewed from the rear end of the boiler.
The object of my invention is, rst, to perfect the consumption of fuel in the furnace of steam-boilers, and of the gases developed in the process of combustion; second, to avoid the necessity of delivering the exhaust steam from a locomotive-engine in the smoke-pipe of the boiler to increase the draft of the furnace.
And my invention consists, rst, of certain devices applied to a boiler, by which a stream of hot air is delivered upon the surface of the r re to perfect the combustion ofthe fuel-gases;
second', of certain improved devices applied to a steam-boiler, by which a stream of hot air is drawn down around the smoke-pipe, and thrown upon the surface of the fire in the `boiler-furnace by the motion of the boiler, or
of the engine or vehicle which carries the boiler third, of certain improved devices applied to the boiler of a steam-engine, by which a stream of air is created, drawn down and thrown in the furnace by the motion of the boiler, and heated by the waste or escaping heat of the re on its passage to the furnace.V
`surface of the re.
box is shown by A, the grate-bars by H, the.
tubes by B, the shell or'water space by E, the smoke-box by C, and the smoke-pipe by F. These are parts of the ordinary locomotiveboiler, and in almost the usual form, with the exception of the smoke-pipe, which in this case is incased in a funnel-shaped air-receiving pipe, shown by c, made larger than the smokepipe, by which there is left an annular space between the two pipes, as shown by c. rlhis air-receiving pipe is fitted upon an air-chamber shown by c in Fig. 2 of the drawing, the smoke-pipe passing down through the airchamber to the: smoke-box in which it islocated.
To the 'air-chamber there is connected va series of small tubes or pipes, a a a a, which pass through the ilues of the boiler to the ijrebox A, and connect upon a pipe or chamber, b, located in the top of the fire-box over the re, in the best manner to most effectually expose it to the heat of the furnace.
Into the heating pipe or chamber b there are inserted two or more pipes, d d., leading to the outsideof the boiler-front, as shown in Fig. 2. The out ends of these pipes are fitted with .valves ff, and are connected. to small pipes c e leading into the front of the furnace.
The air-pipe c, it willbe seen, is fitted with a fun nel-shaped nozzle, the capacity of which may be increased should it be necessary to supply the required amount of air, by multiplying the nozzles, as shown by hand t, though it is thought that one nozzle will be sufficient. But the shape must, of course, be modified with reference to catching the air when the pipe is in motion, or in the case of stationary engines, when the wind blows from any direction.
The operation is as follows: The air, when the pipe is in motion, is forced down through the receiving-nozzle to the chamber C, from whence it passes through the tubesa to the pipe or chamber 1),. and from thence through the pipe d and e into the furnace upon the top of the lire, the supply being regulated by the valves ff.
It Will be seen that the air begins -to heat from the time it strikes the smoke-pipe, and continues to increase in temperature until it strikes the re, Where it enters in combination with the hot gases of the fuel, and'becomes itself a part ofthe fire it is intended to intensify.
The leading idea of this invention is, by improved means, to increase or intensify the heat of the furnacebydischarging upon the surface of the re a stream of highly-heated air, to combine with the gases of the fuel in combustion upon the top of the fire. l By the arrangement of the smoke-stack shown in the drawing the engine can still exhaust the smoke-pipe in case of need, though it is thought that the heat and draft of the furnace under this system will be sufficient Without it, by which the noise vand dirt occasioned by the blast in the smoke-pipe can be avoided.
Having now described the nature of my invention, and the means of carrying the same in' practice, I claim to and desire to secure by Letters Patent- In combination with a locomotive or stationary steam-boiler, a superheater, consisting ot a iiue formed around the smoke-pipe, and connected to a series of `pipes arranged in the heating surface and furnace of the boiler, substantially in the manner described, for the purpose specified.
WM.. G. FORD.
