JOSEPH L. CHAPMAN, OF I-IADDONFIELD, NEW JERSEY, ASSIGNOR TO WVILLIAM HARRY MATTSON, OF PHILADELPHIA, PENNSYLVANIA.
STEAM OR HOT-WATER GENERATOR.
SPECIFICATION forming part of Letters Patent No. 617,393, dated January 10, 1899.
Application filed September 28, 1898. Serial No. 692,047. (No model.)
To (all whom it may concern:
Be it known that I, JOSEPH L. CHAPMAN, a citizen of the United States, residing at Haddonfield, in the county of Camden, State of New Jersey, have invented a new and useful Improvement in Steam or Hot -Water Generators, which improvement is fully set forth in the following specification-and accompanying drawings.
My invention consists of an improved construction of steam and hot-Water generator in which provision is made for rapidly and effectively raising the temperature of the steam or hot water to a'high degree and utilizing the heat units of the products of coinbustion.
It also consists in the employment of an outer water-jacket constructed in segmental sections and of a novel construction of key or locking device common to a pair of said sec tions.
It also consists of an improved construction of internal water-chamber and of novel means for making the connection therefrom to the outer sections of the water-jacket.
It also consists of a novel construction of heat-deflectors and wings upon which said deflectors are supported, said wings extending radially from an internal water-holding chamber.
It also consists of novel means for closing under all conditions the opening in the waterjacket sections through which pipes pass common to said sections and an internal chamber.
It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.
Figure 1 represents a side elevation of a steam and hot-water generator embodying my invention. Fig. 2 represents a top plan View of the interior of the generator, the top portion of the latter being removed. Fig. 3 represents a vertical sectional view of the generator, the section being taken on line so :0, Fig. 2. Fig. 4 represents, on an enlarged scale, a perspective view of an internal waterholding chamber, the same being shownin detached position. Fig. 5 represents a side elevation of the upper portion of the waterholding chamber showing, one of the heat-deflectors placed in position. Fig. 6 represents a perspective View of a pair of adjacent sections of the boiler, showing also the upright key or means for locking'the sections in assembled position. Fig. 7 represents a perspective View of a device employed for deflecting or retarding the flow of products of combustion,the same being shown in detached position. 7
Similar letters of reference'indicate corresponding parts in the figures.
Referring to the drawings, A designates a sectional boiler, the same beingcomposed of a plurality of sections B, the same being in the present instance of segmental shape and four in number, although it is of course evident that the number thereof may be increased or diminished according to requirements. Each of the sections is made hollow, as will be understood from Figs. 3 and 6, the same when assembled forming a cylindrical or similarly-shaped water-j acket, as will be apparent from Fig. 2.
The manner of holding or looking the sections in assembled position will be best understood from Figs. 2 and 6, each section being provided with an inner recessed por- F, as will be understood from Figs. 2 and 6,
it being apparent that the sections are assembled' by being placed in upright position and in proximity to each other, after which the locking device or key F is inserted in the manner indicated in Fig. 6 and forced downwardly, whereby it will be apparent that the sections will be rigidly held, in assembled position.
H designates an internal Water heating chamber, the same consisting of a cylindrical or other shaped body J, which has the arms K projecting therefrom, the lower opposite pair of said arms having pipes L projecting therefrom into the elbows ,M, from which the pipes N lead downwardly into the branches P, which communicate with one of the outer sections of the water-jacket, the latter having openings Q therein, through which said pipes L pass.
In order to provide for expansion and contraction and to keep the openings Q closed, I employ a sleeve G, through which passes the pipe L, said sleeve having a flange G which closes said opening.
G designates a spring having one end bearing on said flanges, while its other end bears against the elbow M.
R designates an inlet-pipe which communicates with one of the branches P, whereby the water is initially fed to the heater, it being noted that the water is simultaneously fed to one of the arms K and also to the lower portion of one of the water-holding sections B, whereby an effective circulation is at once attained, as is evident.
S designates a series of flattened, radiallyextending, wedged, or similar shaped wings which extend from the upper portion of the internal chamber 11 and are provided with depending lugs T, which rest upon the upper portion of the water-jacket sections B, whereby said chamber is supported and a free passage is afforded for the products of combustion around said wings, as will be evident.
U designates pipes which lead in the present instance from an opposite pair of the wings S into a coupling V, the upper portion of which is preferably flanged, whereby connection can be made to the points to which it is desired to conduct the steam or hot water, said passage V also communicating by means of the pipe \V with the upper portion of the adjacent water-jacket section B.
Provision is made for insuring proper circulation between the water-jacket sections by means of the exterior circulatingpipesX, and additional means are also provided for enabling the sections to be securely held in assembled position by means of the oppositely-located sets of lugs Y and the bolts or similar devices Z, which are common thereto.
It will be noted that a space exists between the adjacent upper water-holding Wings S,and in order that the products of combustion may not pass too freely therebetween I support thereon a heat deflecting or retarding device A, the general construction of which will be apparent from Figs. 2, 5, and 7, the same consisting of a body portion-B, having the lips or lugs 0, whereby they are supported upon the water-containing wings S, as will be evident from Fig. 5.
D designates the top of the boiler, which is supported in any suitable manner and may be provided with an outlet or flue, as is customary, for the passage of the products of combustion.
E designates a magazine which is in the present instance supported upon the top D and depends to a point near the termination of the chamber J above the grate F.
It will of course be understood that the boiler is provided with the usual appurtenances, such as ash-pit, fire-doors, draft-regulators, and all similar adjuncts.
The operation is as follows: The cold water enters the pipe R, which may be provided with a valve, as is customary, and passes thence through the pipes P and L into the .lower portion of the water-jacket sections and into the arms K, respectively, whence it freely and eifectively circulates throughout the boiler. The heated water or steam leaves the boiler through the pipes U and V and is conducted through the passages V to any desired point, as is evident.
It will be seen that in a boiler constructed as above described an unimpeded circulation is at all times attained, since a suitable body of water is always contained in the chamber J, which is directly above the fire and exposed to the hottest portion of the products of combustion, and the water in said chamber J being initially heated to a high degree will cause an eifective circulation under all conditions, as is evident.
By the provision of the wings S a too rapid egress of the products of combustion before the heat units are extracted therefrom is prevented, and by the employment of the arms K in addition to said wings a maximum quantity of water is exposed to the effects of the products of combustion.
It will be apparentthat, if desired, the 1101- low internal water-chamber H can be removed after disconnecting the pipes and other adjuncts, whereby I can use the remaining portion of the generator as a stove, as is evident.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
