EDWARD P. VAGGONER, OF SYRACUSE, NEW YORK.

i GENERATOR;

SPECIFICATION forming part of Letters Patent No. 534,459, dated February 19,1895.

.Application led April 4,1894. Serial No. 506.268. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, EDWARD P. WAGGONER, of Syracuse, in the county of Onondaga, in the State of 'New York, have inventedV new and useful Improvements in Generators, of which the following, taken'in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in generators, particularly applicablev for yheating dwellings and other buildings by steam, and has for its object the production of a device, which is simple in construction, economical in manufacture, produces a positive circulation of .the water within the same, is capable of considerable expansion and contraction without liability of leakage, and is highly efficient and durable in operation; and to this end it consists, essentially, in a series of hollow sections of angular cross section arranged one above the other and connected together, one or more of said sections consisting of opposite connected divisions. y

The invention also consists in generatorv sections provided with upright i'lues, the lower section having cut-outs orbranch iues extending laterally from said tlues, downtlow lpassages having their opposite extremities connected to the chambers of the upper andf` lower sections and their intermediate portions unconnected with the chambers of the interposed sections, and inclosed'bolt receiving passages unconnected with the chambers of the sections, securing. bolts passed through said inclosed chambers of 'the sections, and yielding washers provided upon said bolts for permitting expansion and contraction of the generator withoutvimpairment of the connection between its sections and consequentliability of leakage.

The invention furthermore consists in the detail construction and arrangement* ofthe parts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specilcation,in which like letters indicate corresponding parts in all theA views. p Figure l is an isometric View, partly in section, of my improved generator, Eig. 2 is av front elevation of the generator.l Fig. 3 is a an isometric perspective of a lower portion of the bottom section of the generator. y

A is a suitable base provided with an ash chamber c', and any desirable constructionof grate a', and B is an outer casing suitably secured to or mounted upon a `flange a2 at the upper extremity ofthebase-A.

The outer casing B, which may be provided with suitablecleaning doors, is preferably of angular cross section as my improved generator is of similar form and the Lipper edge ofthe casing is secured to the top section of the generator presently described.

O D E F are the sections of my generator, which vare preferably arranged one above the other, and are connected together by waterways g consisting, preferably, of apertures formed in corresponding portions of adjacent walls of said sections. For facilitating their handling and assemblage, the sections O D F. F preferably consist-of opposite divisions c o,

-d d, c c, and ff, each provided with an independent chamber, but it is ,evident that each ot' said sections may consist of a single chamber.`

.The sections C DE are constructed in the vform of a hollow square, andjconsequently the opposite extremities oftheir divisions c CZ e are formed with similar hollow arms cd c v arranged with the outer faces of opposite arms in close proximity to each other. The inner faces of the sections C D are substantially smooth and form the upright walls of the coinbustion chamber. t

Opposite sides of the section E are pro vided with hollow heating chambers E of less thickness than width, which project above the combustion chamber to substantially the central portionthereolso that adjacent faces of opposite heating chambers E are in close proximity to each other. The products of co1nbustion impinge against the lower walls of the IOO heating chambers E', and then pass readily between the same. A great amount of heating surface is thus subjected to the action of the products of combustion, and the peculiar 5 construction and arrangement of the heating chambers E tend to effect a positive circulation of the water within .the generator.

The top section or dome F of the generator consists of a substantially flat hollow plate or 1o body and the adjacent faces of its opposite divisions are arranged in close proximity to each other. The corners of the top section F are provided with depressed portions F resting upon the section E, and the remaining; t5 portion of the lower face of said section F is substantially flat and is considerably sepa rated from the top face of the section E. The lower wall of the section F thus forms addi tional heating surface subjected to the action zo ofthe products of combustion passed between the heating chambers E', and the space between the adjacent faces of the sections E F forms a flue or chamber for receiving the products of combustion and conducting the same to downwardlj7 extending ues, presently described.

In order to equalize the passage of the return water to the opposite divisions of the section C which inclose the upper chamber of 3o the generator and the pressure within the divisions of the section F, which inclose the lower chamber of the generator the divisions c c, and ff, of said sections are connected together by projecting pipes C' C', F2 F2, and j connecting pipes C2 F3. The pipes F2 F2 extend upwardly from the section F, and steam pipes F4 F4 extend upwardly from the opposite ends of the pipe F3 and form continuations of the pipes F2 F2.

The sections G D E F are formed with upright flues c2 d2 e2 f2 alinged with each other, and these flues are -preferably formed of greater width than thickness. Each side of the sections C D E is formed with two independent flues, and each side of the section F is formed with a single flue of a width exceeding the combined width of the corresponding fines in the former sections. The lower section C is provided with a series of cut-outs or branch iues c5 extending upwardly from its lower edge and laterally from the ues c2 for permitting the escape of the products of combustion therefrom to a heating chamber H interposed between the outer walls of the sections C D E and the inner face of the casing B. The chamber H is provided with one or more baffle plates h h for directing the path of the products of combustion and the outer casing B is formed with an outlet opening from which extends a smoke or draft pipe B2.

` It is thus apparent that the products of combustion pass from the chamber or space interposed between the sections F E downwardly through the iiues c2 cl2 e2, outwardly through the cut-outs or branch flues c2 into the chamber H, and thence outwardly through the pipe B2. The lues f2 in the chamber F receive a portion of the products of combustion, but are mainly used for the purpose of facilitating the entrance of a cleaning brush or tool through the chamber F into the flues in the underlying sections. It is also desirable to clean the adjacent faces of the sections C D E and the casing B, and consequently the section F is formed with suitable flues]3 arranged at the outside of the ues f2. Each of the flues f2 and the adjacent flue f2 are covered by a cap F5 of sufficient width.

As previously stated, the peculiar construction and arrangement of the heating chambers E' tend to produce a circulation within my improved generator, but I render this circulation positive and eective by providing the generator with one or more downfiow passages I having their upper and lower extremities connected to the chambers of the upper and lower sections of the generator and their intermediate portions unconnected with the interposed sect-ions. These downtlow passages are preferably arranged in the corners of the sections of the generator at `the outside` of the water connections thereof, and consist, essentially, of openings i t" in the upper and lower Walls of the sections C F, and passages i2 123 formed in the sections D E and aligned with said openings. The passages i2 i3 are, as previously stated, unconnected with the chambers. of the sections D E, and consequently any water within the section F passes positively and quickly down the downflow passages and into the lower section C, thus producing a positive and effective circulation of the water within my improved generator. This result is evidently auxiliar-ated by the peculiar arrangement of the downflow passages at the corners of generator sections of angular cross section.

The separate sections of my improved generator are secured together in any desired manner, but I preferably secure the same by upright bolts .I passed through said sections and provided at opposite ends with suitable shouldersjj, one of which is adjustable toward and away from the other. A yielding washer l7'2 is interposed between one of the shoulders, and the adjacent face of the corresponding sectionof the generatolyand consequently the generator is free to expand and contract without impairment of the connection between its sections or undue straining of the parts or liability of leakage, since the washerj2 yields to permit of expansion, and assumes its normal position when the parts contract.

lt is extremely desirable to protect the bolts .I from the corrosion, which `would inevitably result were they passed directly through the water-containing chambers of the sections of the generator, and consequently these sections are provided with passages or apertures c4 d4 e4 f4 unconnected with the chambers of the sections and aligned one with the other for receiving said bolts J. The chambers c4 d4 e4f4 are interposed between the correspond- IIO The operation of my inventionwill be read-- ily perceived from the foregoing description and upon reference to the drawings, and it will be particularly noted that the same'consists of a series of parts, which are cheaply manufactured, easily transported and readily assembled, is simple in construction, produces a positive and ell-'ective circulation of its contained water, presents a great amount v l of advantageously located heating surface, is not liable to become unduly strained, or leak when subjected to expansion and contraction,

' and is highly efficient and durable in use.

"My improved generator may be vused for hot water heating, and the exact detail construction and arrangement of its parts may be considerably varied without departing from the spirit of my invention, and hence I do not herein specifically limit myself to such exact detail construction and arrangement.

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