Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed November 14, 1905, Serial No. 287,290.

To all whom it may concern:

Be it known that I, MATHEW RAPP, a citizen of the United States, residing at Morton, in the county of Tazewell and State of Illinois, have invented a new and useful Boiler, of which the following is a specification.

This invention relates more particularly to boilers for heating purposes, though perhaps useful in other relations.

The principal object is to provide a simple structure of a novel nature wherein the parts can be readily manufactured, are entirely accessible, and are not liable to be burned out, said structure maintaining the water and products of combustion in intimate relation during the passage of the latter through the boiler, thereby effectively utilizing the heat from said products of combustion.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of the boiler. Fig. 2 is a vertical sectional view through the same. Fig. 3 is a horizontal sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a top plan view of the furnace. Fig. 5 is a bottom plan view of the cap-section. Fig. 6 is a detail sectional view through the abutted walls of the two sections, showing the communication between the chambers of said sections. Fig. 7 is a detail prospective view of one of the double closures. Fig. 8.is a detail perspective view of the single closure employed.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a furnace is provided that is made up of a base-section 9 and a top section 10. The base-section is in the form of a ring having an annular waterchamber 11 therein and a central combustion-chamber 12, a suitable grate 13 being located beneath and constituting the bottom of the combustion-chamber. The top section 10, constituting the upper portion of the combustion chamber, 1s provided with a doorway 14 and a series of outwardly-extending outlets 15. This top section is also provided with a water-chamber 16, that par tially surrounds the outlets and is in communication with the chamber 11 by means of openings formed in the abutted top and bottom walls of the two sections, one of said walls having nipples 17, that pass through ing the means of communication between annular water-chambers 23 in the said bodysections. Flue-sections 24 are located in the body-sections and are completely surrounded by the water-chambers. These flue-sections are in alinement and a plurality of the same communicate at their lower end with each of the outwardly-extending outlets 15.

Mounted on the top of the body is a smokeboX section 25 in the form of a ring having an annular chamber 26 communicating with the upper ends of the various flues 24. This smoke-box section is, furthermore, provided in its top with a series of openings 27, alined with the various flues, one of the openings 28 being located at one side and constituting a smoke passage-way. A cap-section 29 is located on the smokeboX section and is in the form of a ring having an annular smoke passage-way 30, with which the opening 28 communicates. The cap-section 29 is provided with a smoke-outlet 31, located on the opposite side to the openin 28 and designed to be connected to a suitable stack or pipe 32. This cap-section is provided in its top with openings 33, which openings are in alinement with the openings 27, so that the upper end of the flues are accessible through the alined openings. Under ordinary conditions,

however, the various openings, with the exception of that designated 28,-are closed, and

for this purpose closures 34 are provided for the cap-section, which closures rest upon the {pp thereof and are provided with depending s 35, carrying at their lower ends closures 36 that enter the openings 27. A single closure 37 is provided for the opening in the cap-section that is over the opening 28. The various sections are secured together by suitable tie-bolts 38. A return-pipe 39 commu nicates with the base-section of the furnace, and supply-pipes 40 are in communication with the upper end of the same, these various pipes leading to the points of use, as will be readily understood. With this structure it will be apparent that the combustion-chamber and various fines are completely surrounded by water, so that there is little danger of the same becoming burned out. Moreover, by this arrangement the water is in intimate relation with the products of combustion until the same leave the boiler, and a high degree of efficiency is thereby secured. It will be apparent that the sections of the structure can be readily manufactured and assembled, and, furthermore, should one or more become injured or useless from any cause the same can be replaced without the necessity of an entirely new boiler.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art with out further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the s irit or sacrificing any of the advantages o the invention.

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

1. In a boiler of the character described, a body composed of sections secured together, said sections having communicating flue portions forming separate and independent flues through the body and communicating waterchambers, and a furnace communicating with said independent flues.

2. In a boiler, a body composed of sections secured together, said sections having alined flue-sections and water-chambers surrounding the same, said sections having abutted walls that cut off communication between the flue-sections that are out of alinement and form independent flues through the body, said water-chambers of the different sections being in communication, and a furpiace communicating with the independent ues.

3. In a boiler of the character described, a body composed of hollow sections superposed one on the other and having top and bottom walls, the bottom wall of one resting on the top wall of the adjacent section, said coacting top and bottom walls being pro vided, one with an opening and the other with a nipple fitting in the opening and con stituting means of communication between the interiors of the different sections, alined independent flue-sections extending through the hollow sections, forming independent flues through the body and a furnace communicating with the flue-sections.

4. In a boiler of the character described, a body composed of hollow ring-sections having tops and bottoms, the bottom of one sec tion resting upon the top of the section beneath, flue-sections extending through the ring-sections in spaced relation to the side walls thereof, and forming independent flues through the body and a furnace communicating with the flue-sections.
