HENRY c.. KEASEEY, oE AMBLER, PENNSYLVANIA.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 525,553, dated September 4, 1894. Application iiled January 18,1894- Serial No. 497,245. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY G. KEASBEY, a citizen of the United States, residing at Ambler, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Steam-Boilers, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a steam boiler having a feed water heating device, so combined therewith that the latter serves both to assist the circulation and to gradually heat the water, while it is being converted into steam, the same being formed with separate chambers, which are in communication in such manner that the water is caused to traverse the boiler alternately from top to bottom,vthrough`out the chambers in zig-zag order, whereby it is subjected to the action of the heating flues which extend continuously in an unbroken line from end to end of said boiler through said chambers andpartitions and steam is rapidly and effectively generated at the fire box end of the boiler, all as will be hereinafter set forth.

Figure 1 represents a longitudinal section of a steam boiler embodying my invention. Fig. 2 represents a side elevation of a portion of a modification. Fig. 3 represents a longitudinal section of aportion of a modification. Fig. 4. represents a side elevation of a portion of a modification.

Similar letters of reference indicate correspending parts in the several figures.

Referring to the drawings: A designates a steam boiler, and B designates the ilues therein for the passage of the products of combustion. Within the boiler are partitions or diaphragme C, which divide the boiler into chambers D, D', D2, D3, it being noticed that the ilues B pass through said partitions and chambers.

Connected with the partitions, at or near the upper ends thereof, are pipes E, E', E, which extend downwardly therefrom, and open into the chambers which they occupy at or near the bottoms of the same, thus forming a communication between the chambers, and a zig-zag passage, for the water throughout the boiler.4

TheV boiler and partitions C are provided with man-hole openings and plates F, for admission to the chambers for repairs, and

cleansing the boiler and pipes Gfor blowingout deposits or sediment, and emptying purposes.

S designates the lire box of the boiler,vthe steam space of which being over the crown sheet, whereby the steam is finally generated inthe hottest portion of the boiler. r

The operation is as follows: Water is directed by the feed pipe H into the chamber D lof the boiler, and rising therein reaches the opening leading to the pipe E, so that the walter enters said pipe and is directed by the same to the bottom of the chamber D', where it is discharged. It then rises in said chamber D and reaches the pipe E', by which it is discharged at the bottom of the chamber D2, and thus the operation continues through said chamber D2, the pipe E2 and chamber D3, it being noticed that while the water may be admitted into the boiler in a cold or cool condition, itis subjected to increased heat as it approaches the furnace, and as it traverses the boiler in a zig-zag course, or alternately from bottom to top and topto bttom, it is subjected to increased heating surfaces presented by the flues which it passes, so that steam will be effectively and rapidly generated, the same entering the steam space J and steam dome K.

In Fig. 2, I show pipes L, which are located on the outside of the boiler, and communicate with the top of one chamber and' bottom of the adjacent chamber, as at M and N.

In Fig. 3, I show a pipe P, which is located within one of the chambers of the boiler, and passed through the shell of the boiler, where it is connected outside of the same by a pipe Q, with the adjacent chamber, the operation however being the same as in Fig. l.

In Fig. 4, I show an upright boiler which is divided into horizontal chambers, and provided With pipes R, whereby the water enters the bottom of the upper chamber, discharges at the top of the same into a pipe which lenters the next chamber below, at the bottom thereof, and so on throughout the other cham,- bers, so that the course of the water is zigzag, or alternately from bottom to top and top to bottom through the different chambers, the effect being the same asin the previous cases.

ICO

In two applications led by me of even date Y herewith, Serial Nos. 497,243, and 497,244, for feed water kheating devices per sc separate and distinct from the boiler, I have shown and claimed aY construction adapted in one case to utilize hot gases and products of combustion alone, one end of the heater being open and adapted to be connected with the flue of a boiler and to receive the said hot gases therefrom, the said heater being adapted to be employed in connection with any style of boiler desired, the other parts being also arranged with this especial object in view. In the other case the feed water heater is adapted to be used in connection with a suitable source of steam heat alone, both ends of said heater having an inclosed chamber, and the location of steam inlet and outlet and drips, &c., therefor being arranged with this especial object in View. This heater being also designed to be used in connection with any suitable construction of boiler.

In the present case the heater and boiler are combined into a single structure, and the connections from the different chambers to the several adjacent chambers are made pref erably exteriorly of the boiler.

Having thus described my invention, Vwhat I claim as new, and desire to secure by Letters Patent, is

1. A steam boiler having partitions therein forming separate chambers, lues extending continuously in unbroken line from end to end of said boiler, through said chambers and partitions, and pipes connecting with said chambers, exteriorly of the boiler, forming 35 communications between the said chambers in zig-zag order, the water being introduced into a chamber remote from the tire box, and the steam chamber being over the rc box,

said parts being combined substantially as 4e.

described.

2. A steam boiler having partitions therein, forming separate chambers, /lues extending continuously in unbroken line from end tn Y end of said boiler, through said chambers and 4.5 partitions, pipes connecting with said chambers exteriorly ofthe boiler, forming communications between the chambers, said pip extending alternately from bottom to top and,`

top to bottom of said chambers, a fire boxaul'`4 5o a steam dome, said partsbeing combined substantially as described.

3. A steam boiler provided with a re bell, f
