STEAM BOILER.
$10 433,405. Patented July 29, 1890.
clear, and exact UNITED STATES PATENT OFFICE.
JOHN F. GRAY, OF PROVIDENCE, RHODE ISLAND.
STEAM-BOILER.
SPECIFICATION forming part of Letters Patent N 0. 483,405, dated July 29, 1890. Application filed January 20, 1890. Serial No. 337,482. (No model.)
To all whom it may concern.-
Be it known that I, JOHN F. GRAY, of Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Boilers, of which the following is a description sufficiently full, to enable any person skilled in the art or science to which said invention appertains to make and use the same, refer.- ence being had to the accompanying drawlngs, forming part of this specification, in which Figure 1 is a vertical transverse section of my improved boiler, and Fig. 2 a central vertical longitudinal section of the same.
Like letters and figures of reference indicate corresponding parts in both figures of the drawings.
My invention relates especially to improvements in water-jackets for steam heating apparatus, being designed as an improvement on the boiler shown in United States Letters Patent No. 394,852, dated December 18, 1888, granted to me for new and useful improvements in boilers; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the main boiler, and B the supplemental boiler or waterjacket. A cylinder D is incased in brickwork E, which forms a furnace provided with a chimney b at its forward end. The cylinder D forms the fire-box and ash-pit and the outer wall of the jacket 13. A horizontallyarrauged grate f is supported on lugs g, disposed centrally in the cylinder. A metallic plate 71, nearly semicircular in cross-section, issecured to the inner walls of the cylinder at the lugs g, and forms the inner wall of the water-jacket B, the ends of said jacket being closed by the ends of said plate, which are bent or curved upward to meet the cylinder D and form heads 1' for the jacket. The mouth of the fire-box and ash pit above and below the grate f is closed by doors or p. The
inner end of the grate rests on a back piece q, and the space between said back piece and the inner end of the cylinder is bricked in at r to cause the heat to be directed upward against the jacket.
The main boiler A is mounted in the furnace E, directly above the jacket B and is connected therewith by a series of vertical circulation-pipes t, any desired number of which may be employed.
'lhe'boiler A has a series of horizontal tubes 1) in the usual manner, and a steam-chamber 10, into which a steam-eduction pipe a; opens. A transversely-arranged wall 15 in the rear of the furnace supports the inner end of the boiler proper. The space between the inner end of the jacket B and said wall forms a chamber 16, in which metallic oven 17 is disposed in such manner that the hot air from the firebox will pass completely around said oven. A horizontal partition 18, connecting the top of the oven and jacket, prevents the air from passing directly over the jacket,a flue 25 being thus formed around said oven.
The oven is designed to be used for baking or cooking purposes and opens through the furnace-walls, being provided with a door 19 at each end. A draft-flue 20 opens through the side of the furnace into the ash-pit of the fire-box, and is provided with a door 21. A feed-pipe 22 leads into the jacket for supplying it with Water, which passes through the connecting-pipes t into the boiler A.
In the use of my improvement water is introduced into the jacket through the feedpipe, and passing through the circulationpipes 15 rises into the boiler A. 'Fire being started in the fire-box, the hot air and products of combustion pass through the rear end thereof and impinge against the adjacent wall of the oven, and being deflected downward thereby passes through the flue 25 over the oven and water-jacket into the smokebox 26, thence through the boiler-tubes into smoke-box 27 and over the boiler A into chimney b. The oven being directly in the path of the hot air is rapidly heated thereby.
The circulation-pipes t are formed in sections coupled together, so that they may readily be detached when it becomes necessary to replace the water-jacket or repair the boiler.
It will be seen that the evaporation-surface in my improved boiler is greatly in excess of those of ordinary construction.
By forming the outside plate of the jacket and the fire-box of a continuous cylinder and ri vetin g the inner plate of said jacket thereto, as described, these parts are greatly strengthened and rendered less liable to leak or open out by pressure. Moreover the inner plate can be readily replacedon the cylinder when burned away, and thus avoid the necessity of substituting an entirely new jacket.
Having thus explained my invention what I claim is- 1. A combined fire-box and water-jacket, comprising a metallic cylinder having a semicylindrical inner plate secured to the upper half thereof forming a water-jacket with said cylinder, substantially as described.
2. The cylinder D, provided withthe grate f, in combination with the plate h, riveted to the cylinder and forming the jacket B, the circulation-pipes t, and feed 22, arranged substantially as and for the purpose set forth.
JOHN F. GRAY.
