SPECIFICATION forming part of Letters Patent No. 473,055, dated April 19, 1892.
Application filed May 22, 1891. Serial No. 393,688- (No model.)
To all whom it may concern: I
Be it known that we, GEORGE BOLTON and Laws R. BOLTON, subjects of the Queen of Great Britain, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Boilers; and we 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 letters of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in heaters or boilers specially designed for heating the water in a hot-water circulating system employed in the warming of buildings in which the pipes of the boiler and circulating system are filled with water, through which heat is transmitted by convection; and it consists in a certain construction and arrangement of parts, as hereinafter fully set forth, the essential features of which being pointed out particularly in the claims.
The objects of the invention are to'provide a boiler that is small and compact, but possessed of the requisite amount of heatingsurface, to reduce the expense of its construction and render its interior easily accessible for the purpose of repairing or replacing any of its parts, and to produce a boiler in which the entire construction is such that the products of combustion are so utilized as to effeet the maximum degree of heat for the quantity of fuel consumed. These objects are accomplished by the formation and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of the b01181 incased as when in operation. Fig. 2 is a perspective view of same, showing the casing removed. Fig. 3 is a vertical longitudinal section through the boiler. Fig. at is a vertical transverse section through the same. Fig. 5 is an inverted plan ofthe hollow cap of the boiler. Fig. 6 is a central cross-section through said cap. Fig. 7 is a plan view of the deflectorplate, showing the d raft-opening therethrough closed by an oscillating damper. Fig. 8 1s a front elevation of the boiler with the case removed. Fig. 9 is a side elevation of Fig.
pot. space occupied by the boiler and is remote from all watercontaining parts thereof.
8, showing the outer series of vertical pipes broken away.
Referring to the letters of reference, A designates the outer frame that incloses the casing or jacket of the boiler. Said jacket is composed of an outer sheet B and an inner sheet 0 of iron with an interposed layer of asbestus D. 'This frame and jacket inclose the four sides of the boiler, the top being jacketed with a layer of asbestus D upon the cap E of the boiler and an outer sheet B of iron, as shown in'Figs. 3 and 4, thereby obviating the radiation of heat from the boiler. The sides and ends of the frame at the top are provided with the horizontal flanges a, that embrace the upper face of the jacket at the top of the boiler, fitting closely thereto, said frame being secured together at the rear by the bolts 0 passing through the rear edges of the sides, whereby by removing said bolts and the remaining portion stripped from the access to all the interior parts thereof. In the ordinary manner of constructing heaters or boilers of this kind they are mounted upon a base or pedestal of metal or brick that forms the ash-pit below the grate of the fire- This base is expensive and adds to the Consequently the heat from the under side of the grate is not utilized, thereby wasting a great percentage of the caloric products of the fuel. In our improved boiler this objection is overcome by doing away with the pedestal entirely and forming the ash-pit directly within the base F proper of the boiler, as shown at G in Fig. 2. Said base is a hollow casting trilateral in form and is substantially rectangular in cross-section. The front of said base, being open, affords free access to the ash-pit, enabling the ashes to be readily removed therefrom.
H designates the continuous vertical side 1 the rear portion of thejacket may be removed pipes of the boiler, the lower ends of which nicate at their rear ends with the base F through the series of vertical pipes K and communicate at their forward ends with the cap E through the series of vertical pipes L. Above the horizontal pipes I is located a series of dependent or drop tubes M, the upper ends of which are secured in the cap E, whose under face is provided with a series of holes a, as shown in Fig. 5, to receive the upper ends of the pipes H L and tubes M, respectively.
N designates the V is hollow, like the base F,and extends across the front of the boiler some distance above said base, forming the sill of the stoke-hole O, as shown in Fig. 3, and also the front wall of the fire-pot, which is formed by said basesection, the vertical side pipes H and rear pipes K, and the grate J. The base-section N communicates with the base F through the short corner-pipes H and with the cap E through the corner-pipes H and adjacent pipes L, as shown in Figs. 2, 3, and 8.
P designates a horizontal pipe, the forward end of which communicates with the basesection N and its rear end with the vertical pipes K through the coupling P, as shown in Figs. 3 and 4. Said pipe crosses the firepot directly over the center of the grate, thereby preventing the overheating and warping of the grate-bars.
V designates a diaphragm, (clearly shown in Fig. 7,) which is located among the droptubes M and through which said tubes pass, there being a space between the edges of said diaphragm and the vertical side and end pipes of the boiler, as shown in Figs. 3 and 4. This diaphragm serves as a deflector to the caloric current, mingling the gases and air so as to insure perfect combustion and throwing said current out against the side pipes of the boiler, when it passes over the top of said diaphragm and out the smoke-flue W through the cap E, thus retarding the volatile products of combustion until thoroughly utilized. In the diaphragm V is an opening that registers with theopening of the flue W and which is controlled by a damper h, actuated by the rodt, by means of which the damper may be i opened to afford a direct draft through the flue when starting a fire or to cause the fire to burn more briskly.
Z designates the hot feed-pipes leading from the cap E of the boiler, and Z the cold return-pipes entering the base F thereof.
X designates the jam-nuts of the vertical pipes of the boiler, which are located at the bottom of said pipes on the base F in the ashpit, where the threads of said pipes are not eaten away by the action of the products of combustion.
In the front of the casing or frame A the upper doorY communicates with the damperrod 25, the center door Y with the stoke-hole front base-section, which 0, and the lower door Y with the ash-pit G, and forms the draft-opening for the fire, also afiording access to the stems d of the revolving grate-bars.
From the drawings and foregoing description it will now be apparent that the construction of this improved boiler is simple,
economic, and compact, in which all the parts are readily accessible, and in which the arrangement is such that the return water is divided into a multiple of small columns and passed through the fire-space in such manner as to receive the full effect of the entire product of combustion, whereby the water is rapidly and intensely heated and given an accelerated circulation.
Having thus fully set forth our invention, what we claim as new, and desire to secure by Letters Patent, is
1. In aboiler, the combination of the hollow trilateral base, the hollow cap,a seriesof vertical pipes connecting said base and cap, the grate located within the area inclosed by said vertical pipes and supported above said base, and a series of horizontal pipes located above the grate, said pipes communicating at their rear ends with the base and at their forward ends with the cap, substantially as set forth.
2. In a boiler, the combination of the hollow trilateral base, the hollow cap, a series of vertical pipes connecting said base and cap, the grate located within the area inclosed by said vertical pipes above the base, and the hollow transverse base-section located above the base at the front and connected by vertical pipes with the base and cap, as set forth.
3. In a boiler, the combination of the hollow trilateral base, the hollow cap, a series of vertical pipes connecting said base and cap, the grate located within the area inclosed by said vertical pipes above the base, the hollow base-section crossing the front ofthe boiler above said base and communicating with said base and cap, and a series of horizontal pipes above the grate, communicating at their rear ends with the base and at their forward ends with the cap, substantially as specified.
4. In a boiler, the combination of the base and cap connected by the vertical pipes, the
grate detachably supported within the area inclosed by said pipes, the drop-tubes depending from said cap, and the diaphragm located among said tubes and havingkthe dampercontrolled opening that registers with the flue through said cap, substantially as and for the purposes specified.
In testimony whereof we affix our signatures in presence of two witnesses.
