UNITED STATES CHARLES H. FOX, OF CINCINNATI, OHIO.
STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 568,438,v dated September 29, 1896.
Application filed May 4, 1896. Serial No. 590,069. (No model.)
To @ZZ whom it may concern:
Be it known that I, CHARLES H. FOX, a citizen of the United States, residing at Cincinnati, Ohio, have invented new and useful Improvements in Steam-Boilers, of which the following is a specification.
My invention relates to steam-generators of the class known as sectional water-tube boilers,its object being to produce a compact generator of high steaming capacity and of simple, durable, and economical construction,
adapted to portable-engine service, &c., as well as for stationary engines.
To this end my invention consists in the generator constructed as hereinafter set forth, producing a self-contained boiler, requiring no brick or other extraneous setting, and possessing all the advantages incident to the sectional water-tube type and the water-leg type combined.
My invention is illustrated in the accompanying drawings, in which-- Figure l is a vertical cross-section of the boiler through the lire-box shell, showing the tube-sections in elevation, one of the manifolds being cross-sectioned to show construction. Fig. 2 is a vertical cross-section in the fore-and-aft plane of Fig. l. Figs. 3 and/I 4are front and side views showing the exterior rear at the top of the boiler, the sheets being perforated correspondingly with the inner circumference of the drum, so as to connect the interior drum-space with the water-leg. rIhe space between the front and rear elevated portions of the water-leg,labove and at the sides of the drum, is covered by a cylindrical ldome-sheet l), out of which rises the chimney c, and the side openings down to the waterleg are covered by removable plates d.
The usual lire-door opening e and grate g are provided.
The inner open space of the lire-box be'- neath the drum B above the grate is occupied by a series of adjacent removable tube-sec'- tions F, each consisting of a number of parallel straight tubes f, set at their ends in vertical manifolds h at an inclination tothe general axis of the manifolds. Each section has preferably two sets of .tubes in adjacent vertical series, the connections of one being offset or staggered in relation to those of the other, in different horizontal planes. The manifolds h are constructed with stepped surfaces at right angles to the longitudinal axes of the tubes f at the engaging sides and are correspondingly formed at the opposite sides and perforated for the insertion of screwplugs h lin the prolonged axes of the tubes f to afford access for convenience of cleansing or removal of the tubes.
Each tube-section is supported at opposite ends by its manifolds, the upper manifold resting directly upon the ledge d3, formed by the half-high water-leg, and the lower upon the corresponding ledge c3, at the opposite side of the fire-box, by means of a projection h2 from the upper end of the manifold, and each manifold is further secured against displacement by bolts x, engaging the feet h2 at the top of the lower manifolds, and corresponding lugs hL1 at the bottom of the opposite upper manifolds,with brackets Iy on the waterleg A, as shown in Fig. l. Any number of tube-sections may thus be arranged side by side, alternating in relatively opposite inclinations, the lower manifolds being thus maintained vertically wholly within the fire-box space, while the upper manifolds rest in the vertical upward prolongation of the water-leg plane. Each upper manifold has a pipe connection p at the top, into the adjacent side of the drum B, and each lower manifold connects at the bottom by a pipe p, into the adjacent side of the water-leg A.
The inner sheet a2 is preferably allowed to extend somewhat above the bottom of the drum B at each end to form a dam a5, with a retention of water in the drum when working IOO the boiler with a scant water supply, or as a protection against accident, and I may also, in connection with this feature, introduce the feedwater into the drum, but these are not material to my invention.
I also introduce in the drum, at or just above its horizontal diameter,a ilat or slightlycurved plate m, with lines of perforations n near cach side, Fig. l, to assist in screening the entrained water from the steam and insuring delivery of dry steam to the steam-delivery pipe Z. To the under side of this plate, near each side, I attach a suspended plate or apron o, which serves to divert the waterentering from the manifold connections p' down ward around the sides of the drum l5, and thus prevent unnecessary mechanical agitation while steaming.
In the drawings I have shown the boiler as supported at opposite sides upon braces r, (of a vehicle g) but it may rest upon the bottom, if preferred, or be supported in any other manner.
The mode of operation and use are as follows: The tube-sections, standing at an inclination in the direct path of the heated products of combustion, cause an upward movement of the water from the lower part of the water-leg through the manifolds and tubes into the drum, which necessitates a contrary movement outward from the drum into the elevations of the water-leg, and thence downward into the intakes of the lower manifolds. The dams a5, as will readily be seen, insure a constant supply of water in the drum to the predetermined level,and the general construction insures a quick circulation of water to every part.
The facility for renewal and repair offered by this construction will be obvious. By removing the side plates d the entire system of tube-sections is exposed. A tube-section can then bc readily detached and removed without disturbing any other connection, and, the apertures of the boiler being plugged, the boiler can be used until proper repairs are effected and the tube-section replaced. Tubes can be cleaned interiorly without removing thetube-scctions from position. It will also be observed that at all exposed portions of the boiler-that is, at the outer sides of the water-leg and its extensions-the circulation is downward, consistently with the natural eifcct of external cooling by radiation, while at all central parts exposed to the heat the circulation is upward; also, that the internal horizontal area of the fire-box space enlarges above the water-leg sides out to the plates d, which enlargement is favorable to the expansion of the gases of combustion and assists the proper action of the fuel.
The boiler is particularly adapted for marine service by reason of its compactness in horizontal dimensions, large heating-surface, vigorous circulation, and facility afforded for repairs. Its size may be increased to any extent by providing an increased number of the tube-sections and lengthening the drum and fire-box without necessarily increasing the width, so that a boiler of great capacity can occupy a narrow space horizontally, which in marine service is a desideratum.
I claim as my invention and desire to secure by Letters Patent of the United Statesl. In a steam-boiler, the combination of a watenjacketed fire-box, a steam-drum above and connected directly with the same, and a series of inclined tube-sections connected at their lower ends at opposite sides within the fire-box to the water-leg, and at their upper, at correspondingly opposite sides, to the drum, substantially as set forth.
2. In a steam-boiler, a water-jacketed iii-cbox, having vertical extensions of the waterleg at opposite ends, a drum connecting and opening through the inner sheets of said extensions, and a series of inclined tube-sections connected at their lower ends to the waterleg at opposite inner sides of the fire-box, and at their upper ends to the drum at relatively opposite sides, substantially as set forth.
In a steam-boiler, a rectangular waterjacketed fire-box, having vertical water-leg extensions, a 'drum connecting and opening through the inner sheets thereof, an d forming a continuation of the inclosed water-space, and a series of adjacent, inclined, independent and removable tube-sections resting at opposite sides upon the water-jacketed lirebox, and having pipe connections from the lower end of each tube-section into the waterjacket of the fire-box, and at the upper end into the sides of the drum, substantially as set forth.
et. In a boiler of the character indicated, the combination of the water-leg vertically extended at opposite ends; a drum connecting said vertical extensions, and dam-plates at Opposite ends of said drum, as set forth.
In a boiler,of the characterindicated, the combination of a water-jaeketed fire-box, an upper, conneeting-drum, and a series of independent, detachable tube-sections supported upon the boiler, independently of their tube connections therewith, substantially as and for the purpose, set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
