HOT-WATE'R HEATER.

SPECIFICATION forming part of Lettersilatent No. 423,759, dated March is, 1890.-

Application filed December 23,1889. Serial n. 334,704. (mater) Be it known that 1, JOHN J. GRAVES, a citizen of the United States, residing at Buffalo,

provements in Hot-Water Heaters, of which the following is a specification.

My invention relates to hot-water heaters adapted particularly for, house-heating purposes; and it consists of a heater of thelnovel construction to be hereinafter pointed out, and constructed ofseparable sections which of themselves contain features of novelty,

In the drawings, Figure 1 is a perspective view of, aheater embodying my invention,

2 is a longitudinal section of the heater. Fig. 3 1s a transverse section thereof. Fig. ,4 is a and Fig. 5 is a horizontal section on the line 'y y of Fig. 3.

The boiler or Water-heater-is made up of a the water circulates and is heated. As these sections are duplicates one of another, but one need be described. It consists of two hollow legs 1 and 2, one longer than the other, and connected with each other by a number of pipes 3, thereby leaving the openings 4, which, when the sections are assembled to form a boiler, become the 'fire-flues for. the passage'of the products of combustion. The pipes 3 are by preference of the shape in cross-section shown in Fig. 2-that is tosay,

which is oval, they are flat on their upper and curved on their lower faces. This shape makes the bottoms or floors of the tines 4 flat, so that they may be easily raked or cleaned out, while the other Walls thereof are curved, and thus present extended surfaces to theheated products of combustion.

It will be observed that the cross-pipes 3 are of the same width as the water-legs 2 and 3,which insures that when the legs are brought together end to end, continuous fines 4 are formed; These Sections are arranged opposite to each other in pairs, their shorter vertogether end to end to form the boiler or 1 JOHN J. canvas, or BUFFALO, NEW YORK, AssIeNoR TO SHERMAN s.

heater, the cross-pipes3 abutting and the openings 4 registering, and. the ends of the heater are closed by bonnets or casings, so as to properly direct the products of combustion through the zigzag flue formed by the openings/1 and the casing-walls and plates. 1

The series of sections A are united by long bolts 6 and '7, passing through lugs or flanges, or preferably, as shown, through the water- .13 of suitable construction, provided with a grate b, so that there is formed a fire-chamber tubes 13 andl t, at the lower and upperpor- 11 above such grate between the long waterlegs 1 and below the lower series 'of pipes 3 of the sections. The ends of this fire-chamber are closed by fire-brick work 8 inside the casing walls, 9, which close the ends of theheater. The shell or casing walls are formed with or have secured to them the -deflectingplates 10, which extend from the said walls across the ends of the heater and opposite the pipes 3. The preferred arrangement of the deflecting-plates 10 is shown in Fig. 2, where they are shown riveted or bolted to the casing or shell walls 9, and incline thence slightly downward to the opposite ends of the alternate series of pipes 3, against which they may abut, so that there is formed a sinuous or zigzag passage for the products of combustion from the combustion-chamber to the exitflue 12. p

17 is a large door in the casing-wall at the front end of the heater, givingaccess to the lines to permit their being cleaned.

The waterspaces of the adjacent sections on each side of the central line of the heater .of the sections A being provided with both an inlet and an outlet port. Such ports as'are not used for the pipe-connections of the heater are closed in the usual manner.

Any number of double sections may be con uected to form a heater, from three to seven being the usual number for ordinary house- 'heatersi A heater made as described is simple in construction and easily setup, and by reason ofthe very extended flue-surface, which throughout its entire length is surrounded by awater-space, is economical in use. Should any section become worn out or be found otherwise defective, it can be' easily replaced at small cost of time, labor, and money, as no particular fitting is required, the sections being duplicates of each other.

. Without limiting myself to the precise construction and arrangement of parts shown, what I claim is- 1. A hot-water-heate'r section consisting of the hollow water-legs of unequal length connec'tcd by two or more cross-pipes of a width equal to the width of the water-legs, whereby, whenthe sections are placed end to end, continuous flues are formed between the crosspipes, substantially as described.

. 2. A hot-water heaterconsisting of a series of hollow water sections, each having a long and a short leg connected by cross-pipes, the sections being united in pairs, with their shorter legs abutting, and such pairs being connected end to end with their cross-pipes abutting to form draft-fiues, through the secand a short leg connected by cross-pipes, the sections being united in pairs, with their shorter legs abutting, and suchpairs connected end to end, a base on which the united sections are placed, and a fire-grate between the longer legs of the section, substantially as described.

4. A hot-water heater consisting, of hollow watersections united end to end and provided with openings through them to form draftfiues in combination with end casing-wallshaving' deflecting-plates arranged adjacent to the opposite ends of the adjacent pipes which separate the draft-passages, substantially as and for thepurpo'se specified.

5. A hot-'water'heater composed of sections united side by side in pairs and such pairs united end to end, and casings or walls. closing the ends of the sections, substantially as described.

In testimony whereofI'afliX my signature in presence of two witnesses.

JOHN J. GRAVES.
