,J O aZ Z whom it may concern:

it. known th'at I, AoeUs'r .VIIE-NRY HARD,

a oi'ti ze hof the .United States," residing at .Keyv'anee, .in the county of Henry and State 'of Illinois, have invented certain new and useful Improvements lVaterJ-Ieaters, of

white the l'follo wing is specification, refertively small and, therefore, the water willbe heated to a higher degree.

Another object ofthe invention isto constfuct atone-in which thewate'r surrounds the fire-box and then passes through the fireboX by means of the water tubes, after which it passes over the fire-box and out through a circulating pipe. It will thus be seen that the water is acted upon three times, that is to say while it passes through the side walls, while passing through the water tubes, and while passing over the roof of a fire-box.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a perspective view of the boiler with the smoke pipe removed. Fig. 2 is a sectional view along the line 2-2, in Fig. 5. Fig. 3 is a section along the line 33, in Fig. 2. Fig. 4 is a section along the line 1-4, in Fig. 2. Fig. 5 is a front elevation of the boiler with part of the front wall broken away. Fig. 6 is a front elevation of the upper portion of the boiler. Fig. 7 is a perspective view of the frame of the boiler with one of the side walls broken away.

Referring to the accompanying drawings it will be seen that this invention comprises a supporting frame 10 which constitutes the ash pit, the upper wall forming the grate 11 and the front wall being provided with the doorway 12 closed by the door 13. The fire-box comprises the upper and lower sections 14 and 15 which are supported by the supportin frame 10. The lower section 14: is provide with hollow side walls 16 which the bed of coals.

lead fro m the hollow rear wall 17. ..This

lower fra nejforms the main portion of the fire-box, and itis this portion whit-hzhol'ds It will,thereforgbenoted that the water which enters the rearwall 17 through'the inlet 18 will extend aboutthree sides of the bed of coals andthat, therefore,

this water willbe heated a "certain amount before passing out of the side wall into "the upper chamberllothrough the openings 19. .Theupper section is provided with the hollow side walls 20 which leadfro'm the hollow rear wall 21. The front wall 22 is also:hol-

low,.but 1s separated from the side walls by a 'partition23 so that the water which ehters the front wall22' will have to pass through the tubes 2 1 in order to reach the rear wall.

.lt should alsobe noted that this front wall provided with a passageway 25 positioned above the tubes 21 so that the tubes may be cleaned of soot when necessary.

The water from the inlet pipe 18 passes along the side walls 16 and up through the openings 19 into the front wall 22. From here it passes through the tubes 24: into the rear wall 21 and backs up into the side walls 20 so that the sides of the boiler will be prevented from becoming overheated by the fire in the fire-box. After the water has passed through the tubes 24-. it will be very hot since the tubes break it up into a number of relatively small streams, thus giving it a chance to be heated to a higher degree than if it passed through the fire-box in a solid mass. As soon. as water passes into the rear wall it passes up through the openings 26 into the cover section 21. This cover section is hollow and is provided with a well 28 so that a smoke pipe for conveying the products of combustion to the chnnney may enter the fire-box through this well. The water passes over the fire-box and is therefore, kept at a high degree of heat and passes out of the cover section through the outlet pipe 29,

The water can be carried to any point desired or if desired may be circulated through a suitable heating system and returned to the inlet pipe to be again heated. The front walls of the boiler are covered by a facing 30 which is provided with a door 31 for closing the clean-out opening 25. The door 32 for the fire-box is also hinged to the facing 30 as is also the door 13 of the ash plt.

Having thus described the invention what is claimed as new, is

1. A boiler comprising a body portion having upper and lower sections, said upper section being provided with a plurality of hollow walls, tubes connecting the hollow walls of said upper section and passing through the fire-box of said boiler, said lower section being provided with hollow walls communicating with one of the hollow walls of said upper section whereby water entering said lower section will pass through its hollow walls and into one of the hollow walls of said upper section and through the tubes into a second wall of said upper section, and a hollow top for said boiler forming a cover for the fire-box, said top communicating with the second hollow wall of said upper section and provided with an outlet whereby the water from said second hollow wall of said upper section will pass through the hollow top across the fire-box and out through the outlet.

2. A boiler comprising a body portion, said body portion comprising a supporting section forming an ash pit, a second section constituting the lower portion of a fire-box resting upon said supporting section, said second section being provided with hollow walls having outlet openings at one end and provided with an inlet opening, an upper section for the fire-box resting upon said second section and provided with hollow walls, one of the walls being in communication with the outlet openings of said second section, tubes connecting the walls of said upper section and passing through the firebox, one of the walls of said upper section being provided with an outlet opening, and a hollow cover for the fire-box resting upon said upper section and provided with an inlet opening communicating with the outlet opening of said upper section and with an outlet opening upon the opposite side of said fire-box from its inlet opening.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
