"MILTON w. HAZELTON, OF CHICAGO, ILLINOIS, ASSIGNOR To HIMSELF AND EDWARD s. T. KENNEDY, on NEW YORK, N. Y. I
SECTIO'NAL BOILER.
SPECIFICATION forming part of Letters Patent No. 224,685,,dated February 17, 1880.
' Application filed August 30, 1879.
T all whom it may concern:
Be it known that I, MILTON W. HAZELTON, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Sectional Boiler, of which the following is a specification.
Figure 1 is a front elevation oft he boiler set in brick-work, partly in section. Fig. 2 is a sectional elevation of the Fig; 1. Fig. 3 is a side elevation. Fig. 4 is a horizontal section on line X X, Fig. 1. Fig. 5 is a horizontal section on line y 3 Fig. 1.

The object of this invention is to. provide a stationary steam-boiler composed of hot-Water, steam, feed-water, and air tubes laid horizontally, in coils or sections, one above another, in the order named, in a brick fire-chamber, and having all the tube couplings and connections outside of the brick-work, so that they may be readily got at for examination or repairs, and having also the steam and mud drums outside of the brick-work; and it further consists in constructing a grate-surface of the full horizontal sectional area of the firechamber.
I and with the grate c.
B B are the hot-Water tubes, set in the lower The chief objects of this construction and arrangement are economy in construction, economy in. fuel used in running the boiler, safety from explosion, and convenience in repairing.
In the drawings, A represents the rectangular brick fire-chamber, provided with the fire and ash-pit doors a, and b, respectively,
part of the fire-chamber A for the generation of steam, all connecting at one end with the feed-water pipes ('3 O, and at the other with the vertical drums D D, which in turn connect with the mud-drum E.
The feed-water tubes 0 O are provided with downward flow of water into the tubes below them, present an efficient obstacle to the return of water or steam that way, and thus they ensame on line W W,-
ash-pit of the boiler. This pipe K occupies a portion of the space within the fire-chamber A above the feed-water pipe 0, and the air forced through it absorbs, much of the heat from the hot gases that would otherwise be lost in their passage up the smoke-stack L.
It will be seen that by this method of construction a separate heater for the feed-water is dispensed with, and the waste heat of the fire-chamber utilized for this purpose, and
that the well-known advantages of applying a heated blast to a boiler-fire can be realized by making use of the otherwise Wasted heat,thus, in fact, making one economy generate others.
A further obvious advantage possessed by this boiler over those commonly in use lies in the fact that the whole surface of the boiler, excepting the pipe couplings and connections, is a fire-surface, is exposed to the flames and hot gases, thereby assuring a maximum rate of heat-absorption by the contained water, and, further, that with so large a fire-surface steam can be generated as quickly with a slow and economical combustion of fuel as can be done in ordinary boilers by the most rapid and consequently wasteful rate of combustion.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of feed-water pipes O 0, hotwater pipes B B, vertical drums D D, mud drum E, check -valves F F, steam -pipe G G, and steam-drum H, constructed and connected with each other substantially as herein shown and described.
2. The air-pipe K, set within a boiler firechamber above the feed-water, steam, and hot- D D and mud-drum E, that are set outside of water pipes, for the purposes herein set forth, the fire-chamber, substantiallyas herein shown 10 in combination with pipes B B, O O, and G. and described. G drums D D and E H and valves F F, substantially as herein shori n and described. MILTON HAZELTON' 3. The horizontal hot-Water pipes B B and Witnesses: steam-pipes G G, set inside of a fire-cham- I.
