STEAM-BOILER.

SPECIFICATION forming part of Letters Application filed February 25,1887.

Patent No. 362,844, dated May 10, 1887.

Serial No. z-zesoo. (No menu.)

To ctZZ whom it may concern:

Be it known that I, GEORGE KINcsLEY, of Leavenworth, in the county of Leavenworth and State of Kansas, have invented a new and useful Improvement in Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying draw mgs, forming a part of this specification.

My invention is in the nature of certain improvements upon the steam-boiler for which Letters Patent were granted me July 31, 1883, No. 282,330; and it consists in the peculiar construction and arrangement of parts, which [5 I will now proceed to describe.

Figure l is a vertical longitudinal section;

Fig. 2, a vertical transverse section. Fig. 3 is a horizontal section through line :0 x of Fig. 2, and Fig. a is a side view in detail of one form'ofdeflector for the hot currents in the fire-chamber.

In the figures, A represents the outer shell; B, the inner shell, having a flat crown-sheet, with drop-tubes 0 extending down into the fire-space; and E are braces extending from the crownsheet upwardly to the outer shell.

The water occupies a position between the outer shell, A, and the inner shell, L, and covers the crown-sheet a few inches, and descends into the drop-tubes, which give great steaming-surface. As so far described, the construction does not differ materially from that shown in my previous patent. The boiler is set, however, with a space, I, on each side 5 between the outer shell and the brick-work or casing, and with a space, J, beneath the boiler. The spaces I on the sides communicate at the rear end of the boiler with the fire-chamber, and at the front ends these spaces I communi- 0 cate with the space J under the boiler, the spaces I and J being separated by horizontal partitions H on each side, which extend to within about four feet of the front end of the boiler. The space J under the boiler at its rear 5 end communicates with a chimney or smokestack, L.

In the space, .I, beneath the boiler is placed a feed-water coil and purifier, G, which has an inlet-valve, G, at the rear, and a bend, F,

with a valve in it, at its front end, which enters the boiler. This coil not only serves as a feed water heater, but it purifies the water by al lowing the sediment to deposit therein; and for cleaning it .out a second valve, G", is pro vided at the rear of the boiler. (See Fig. 3.)

Now,as the products of combustion pass from the [ire-chamber they enter the side spaces, I I, at the rear, on each side, then pass to the front, heating the outside of the shell of the boiler. Then, descending around the front ends of the partitions H, they enter the space J below the boiler, where they heat the lower surface of the boiler and also the feed-water coil G, and thence pass outwardly to the rear into the smoke-stack.

In order to throw the hot-air currents and flames well up into the drop-tubes in the fireehamber, I put two rows, M M, of loose brick in the open space behind the bridge-wall be neath the long tubes, setting them up flush with the bottoms of the long tubes. The first row of bricks I place about half-way between the bridge-wall and the back end of the boiler and the second row I place near the back end. These bricks get red-hot and set fire to all of 7 5 the gases and force them with all hot air up among the tubes, which is an improvement.

In the place ofthese brick deflectors, I may use removable deflectors h which are of a semicircular shape to correspond with the bottom of the fire-chamber back of the bridge-wall, and have projecting feet or flanges at the bottoms, whereby they stand erect upon their own bases by simply being placed in position. Two

or more of these deflectors set in the fire-chamher, as shown, and throw the flames and hot on rrents up among the droptubes, thereby greatly increasing the steaming capacity of these tubes and securing an economy in fuel. These deflectors may be readily lifted out or turned 0 around to permit the bottom of the fire-chamber to be cleaned.

N is a dry-steam chamber connecting with the top of the boiler by pipes I. In these This not drop-tubes communicating with the water only makes a strong connection for bracing the crown-sheet, but also stiffens the connection of the pipes P. K is a blow-off pipe, with valve for removing sediment from the bottom of the boiler.

Having thus described my invention, what I claim as new is 1. The combination, with the outer casing, of the boiler composed of an outer shell and inner shell, with flattened crown-piece, and

space and descending into the fire-space of the inner shell, horizontal partitions H H, dividing the space between the outer shell and the outer easing into side chambers,I Land bottom ehamber, J, the rear ends of the side chambers being in communication with the fire-chamber, and their front ends communicating with the bottom chamber, and the feed-water coil G, arranged in the bottom chamber, substantially as and for the purpose described.

2. The combination of the outer casing, the boiler composed of an outer shell and inner shell, with flattened crown-piece, and droptubes communicating with the water-space I I, and bottom chamber, J, the rear ends of 0 the side chamber being in open communication with the rear end of the fire-chamber in the boiler, and the side spaces, I, and bottom chamber, J, being in open communication with each other at the front end, substantially as and for the purpose described.

3. The combination, with the outer wheel, A, having'pipes 1?, connecting with a drysteam chamber, of the inner shell having flattened crown-sheet with drop-tubes, and braces communicating with said crown-sheet and extended up into and fastened to the inner periphery of the pipes P, substantially as and for the purpose described.

GEORGE KINGSLEY.
