ALEXANDER WV. FINLAYSON, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE- HALF TO CARL SCHWEIKART, OF DETROIT, MICHIGAN.

WATER-H EATER OR STEAM-GENERATOR.

- SPECIFICATION forming part of Letters Patent No. 770,055, dated September 13, 1904.

Application filed March 25, 1904.

To all whmn it may concern:

Be it known that I, ALEXANDER W. FIN- LAYSON, a citizen of the United States, residing at Detroit, in the county of 'Wayne, State of Michigan, have invented certain new and useful Improvements in Water-Heaters or Steam-Generators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a water-heater or steam-generator more expressly designed for heating water for house-warming purposes; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to produce a heater of the character described, of simple, compact, and inexpensive construction, in which the arrangement is such as to cause the return-water from the radiators to pass over the fire before it can again enter the circulatory pipes and wherein provision is made for connecting the heating-pipes in a manner to obviate the use of screw-heads and effect a perfect joint and in which provision is also made for mounting said heating-pipes in independent sections, which may be so placed and so connected with the lower parts of the heater as to allow of a ready removal of any of said sections as desired.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a heater embodying my invention, the casing being partially broken away. Fig. 2 is a fragmentary view in vertical section as on line 2 2 of Fig. 1. Fig. 3 is a fragmentary view in vertical section through the heater as on line 3 3 of Fig. 1. Fig. 4 is a detail in section through one of the removable sections of the heatingpipes, showing the manner of disconnecting said section from the heater for the purpose of removal and to facilitate assemblage. Fig.

Serial No. 199,898- (No model.)

5 is a perspective view of one of theloops of which the sections of the heater are formed. Fig. 6 is a fragmentary section through one of the heating-loops with the parts detached.

Referring to the characters of reference, 1 designatesthe grate, supported in any suitable manner by the retaining-walls 2. Extending parallel to the fire-space are the mud drums or base-pipes 3, into which the returnwater pipes from the radiators (not shown) are connected, as at 4:. Communicating with the base-pipes 3 are the vertical pipes 5, which are provided with a right thread 6 at their lower end (see Fig. 4:) to screw into the tapped boss 7 of the base-pipe and with a like thread 8 at their upper ends adapted to screw into a like boss 9, formed upon and communicating with the interior of one of the divisions 10 of the lower header 11, which, togetherwith the upper header 12 and the connecting vertical pipes 13, constitute a section of the heatingpipes of the heater, of which there may be as many as desired, the number of said sections employed being determined by the desired capacity of the heater. The lower headers are composed of five of the divisions 10, said divisions being connected by the transverse tubular portion 14, whereby communication is established between all of the hollow divisions 10 of the header. The upper header 12 is composed of five of the hollow divisions 15, which are in like manner connected by the transverse tubular portions 16. Each of the divisions of said headers is provided with two reamed apertures to receive the ends of two of the heating-pipes 13, thereby forming when said parts are connected a section of the heater comprising a plurality of loops of two pipes each.

The upper header 12 of each of the sections of the heater is connected by means of the pipe 17, which leads from the boss 18 thereon to the hollow cast receptacle 19, said receptacle affording within it a water-chamber 20. From the lower water-receptacle 19 lead the pipes .21 to the upper water-receptacle 22, from which in turn lead the pipes 23, which carry the hot Water to the radiators. (Not shown.)

The lower water-receptacle 19, which receives the water from the heating-pipes, fits snugly the transverse diameter of the casing 23 of the heater and is provided with draftopenings 24 and 25, through which the caloric current passes into contact with the bottom of the water-receptacle 22, the products of combustion escaping through the stack 26, which passes through the upper water-receptacle and communicates with the space between said receptacles. The passage of the caloric current through the draft-openings in the lower water-receptacle and into contact with the bottom of the upper water-receptacle heats the water therein in addition to the heating the water receives in the pipes immediately over the fire-space. By this arrangement it will be seen that the return water flows into the base-pipes 3, thence into theheating-sections, where it is caused to pass directly over the fire. From the heating-sec tions the water passes to the lower water-receptacle through the pipes 17, 'thence to the upper water-receptacle, and out of said upper receptacle to the radiators through the pipes 23, thereby maintaining a perfect circulation.

It will be observed on referring to Figs. 3 and 6 that the heating-pipes 13 are not screwed into the

opposite divisions

10 and 15 of the headers, but that the opposite ends of said pipes are tapered, as at 27, to fit the flaring reamed seats 28 in the respective .headers, said parts being drawn tightly together by means of the tie bolts or rods 29, which pass downwardly through the divisions 15 of the upper headers, through the pipes 13, and screw into tapped bosses 30 within the divisions 10 of the lower headers, thereby making a perfect joint and connecting the upper and lower headers of the heating-sections, said tie-rods receiving on their upper ends suitable washers 31 and nuts 32, whereby a closure of the opening around said rods is effected and provision is made for applying the proper tension thereto. The connecting-pipe 17 between the upper header of the heating-section and the water-receptacle 19 is in like manner provided with tapered ends 33, which are drawn into the

beveled seats

34 and 35, respectively, in the nipple 18 of the upper header and the lower wall of the receptacle 19 by means of the tie-rod 37, which passes downwardly through the receptacle 19 and screws into the tapped boss 38 within the tubular portion 16 of said header, the upper end of said tie-rod projecting from the face of the receptacle and receiving the washer 39 and the nut 40. By this arrangement a more perfect joint is effected between the pipes and headers of the heating-sections and between the pipes 17 and the upper headers of said sections and the lower water-receptacle than can be made by means of a threaded connection, at the same time affording a joint that is much cheaper than the ordinary threaded joint. An additional advantage in this construction resides in the fact that by connecting the parts in the manner described they can be readily disengaged, so as to enable the removal of any of the sections of the heater, as shown in Fig. 4, or the removal and replacement of the pipes forming the loops ofsaid sections, an accom plishment almost impossible where said parts are connected by threaded joints that are eX- posed to the action of the fire or caloric current.

As before stated, communication is established between the lower water-receptacle 19 and the upper water-receptacle 22 by means of the pipes 21. These pipes, like the pipes 17, are provided with tapered ends 41, which fit into corresponding reamed seats in the

bosses

42 and 43, respectively, projecting from the opposed faces of said receptacles, the joints between the ends of said pipes and said seats being made tight by the tie-rods 44, which pass downwardly through the receptacle 22, the pipes 21, and screw into the tapped bosses 45, the upper ends of said rods receiving the washers 46 and nuts 47 whereby the upper and lower water-receptacles are securely bound together and a perfect joint is made between the ends of the pipes 21 and said receptacles. The circulatory pipes 23 are tapped into the upper water-receptacle 22, and there may be as many of said pipes employed as desired, according to the number of radiators in use.

By the arrangement herein shown it will be evident that the return water, which is only partially heated, cannot pass to the radiators, as is common in some heaters of this class. As herein shown, the return water enters the base-pipes and must pass through the loops of the heating-sections over the fire before it can enter the circulatory system and is thereby subjected to the entire heat of the fire-space. It is also evident that by dispensing with the use of threaded connections and employing the tapered joints herein shown the liability of leakage is minimized and a cheap and perfect joint is effected between the several parts of the heater.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a heater, the combination of a basepipe and a water-receptacle, of a series of independent heating sections interposed between said pipe and receptacle and communicating independently with each, detachable connections for joining said sections to said pipe and to said receptacle, whereby each of said sections is rendered independently removable.

2. In a heater, the combination with the base-pipes and water-receptacle, of a heatingsection interposed between said receptacle and pipe and communicating with each, said section being located directly over the fire-space and comprising upper and lower headers consisting of communicating divisions, pipe-sections having tapered ends seated in reamed apertures in said divisions to connect them, and tie-rods passing centrally through said pipes and engaging the divisions of said headers to unite said parts and form a tight joint.

3. In a heater, the combination with the grate and fire-space, of the heating-sections mounted over the fire-space communicating with the water-return at their lower portions, water-circulatory pipes for feeding the heated water to the radiators, and independent vertical pipes connecting each of the heating-sections with said circulatory pipes which vertical pipes communicate with said heating-sections at a point remote from the casing of the heater and centrally over the heating-space of the furnace.

4. In a heater, the combination with the grate and furnace, of the heating-sections mounted over said furnace and communicating with the water-return, the lower Waterreceptacle filling the transverse diameter of the heater and having draft-openings therethrough, pipes connecting the heating-sections with said lower receptacle, an upper water-receptacle having the stack-opening therethrough, pipes connecting said upper and lower receptacles, which pipes have ta- 5. In a heater the combination with the heating-sections, of the upper and lower water-receptacles, pipes having tapered ends connectin g the heating-sections with the lower receptacle, pipes having tapered ends connecting the upper and lower receptacles, and tierods passing through the lower receptacle and the connecting-pipes into said heating-sections for joining said parts and making a joint between the ends of said pipes, and tie-rods passingthrough the upper receptacle, the connecting-pipes between the'upper and lower receptacles and into said lower receptacle to unite said parts and make a tight joint between the ends of the pipes connecting said receptacles.

In testimony whereof I sign this specification in the presence of two witnesses.

ALEXANDER W. FINLAYSON.
