JOHN F. GRAY, OF VORCESTER, MASSACHUSETTS, ASSIGNOR TO HIMSELF,
AND JAMES C. OONROY, OF PROVIDENCE, RHODE ISLAND.
BOILER.
SPECIFICATION forming part of Letters Patent No. 394,852, dated December 18, 1888.
Application filed May 14, 1888. Serial No. 273,758- (No model.)
To all whom it may concern:
Be it known that I, JOHN F. GRAY, of \Vorcester, in the county of \Vorcester, State of Massachusetts, have invented a certain new and useful Improvement in Boilers, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings,forming part of this specification, in which Figure 1 is an isometrical perspective view of my improved apparatus; Fig. 2, a central longitudinal section of the same; Fig. I), a vertical transverse section taken on the dotted line a: in Fig. 2, as viewed from the right; and Fig. 4, a vertical transverse section taken on the dotted line y y in Fig. 2.
Like letters and figures of reference indi- Cate corresponding parts in the different figures of the drawings.
Myinvention relates to that class of steam heating and cooking apparatus in which a portion of the fire-pot is surrounded by a water-jacket, being designed as an improvement on the steam-boiler shown and described in United States LettersPatent No. 305,073, dated September 16, 188i; and it consists in certain novel features, as hereinafter fully set forth and claimed, the obj ect being to produce a more effective and otherwise desirable 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 b oiler or waterjacket. This jacket is approximately semicircular in cross-section, and consists, essentially, of a double -walled arch or segment which spans the grate C and rests on the j ambs D, said jacket being provided between its walls with a head, f, at either end.
The main boiler A is disposed directly over the jacket B and connected therewith by vertically-arranged pipes E in such amanner as to afford a free circulation of water between the jacket and superposed boiler. I do not,
however, confine myself to the use of any special number of said circulating-pipes, as one or more may be employed in accordance with the size of the boiler or other requirements of the case.
The main boiler, which is arranged in par-' allelism with the jacket, is preferably cylindrical in form, and is provided with a series of horizontal .tlues or tubes, G, in the usual manner, above which there is a large steam chamber or space, ll, from which steam may be taken through the eduction-pipe 45 for heatingpurposes or for driving an engine.
The boiler A and jacket B are incased in the brick-work J to form a furnace, which is provided with a chimney, K, disposed near its forward or front end, but which maybe placed in any other suitable position, if desired. An
iron frame, 95, secured to the front of the brick-work or furnace, and hinged to said frame at T0 there is a large iron door, P. This door is provided with an opening, 60, opposite the front ends of the flues G in the main boiler, an opening, 64E, opposite the firebox 95 beneath the jacket B, and an opening, 67, opposite the ash-pit 84, these openings being respectively closed by doors Q R S, which are hinged to the door P, thereby enabling access to be had to the fines G, and also to the firebox and aslepit, without opening the door P; or by opening said last-named door access may be had to the front end of the boiler A, the jacket B, the circulating-pipes E, the ashpit 8i, and the fire-box 95 at one and the same 8 time. The jacket B extends forward of the main boiler to the door P, or nearly so, and rearward approximately to the center of said boiler, as seen in Fig. 2.
The fire-pot 95 is left open at its front end to enable the coal or fuel to be placed on the grate C, and at its rear end to enable the smoke, gases, hot air, &c., to pass from said box on its way to the chimney K.
In the device secured to me by said Lettion of said boiler bein supported principally by a pillar, lit, and the circulating-pipes E. In my present invention this wall L is moved back nearly or quite to the rear end wall of the furnace or casing J, the rear end of the boiler A being supported by it, as shown at z, the space thus created between the rear end of the jacket and said wall being utilized by a baking or cooking oven, \V. This oven is supported principally by the side walls of the furnace J, and is provided with a door, 17, at each end, through which access may be readily had to its interior from either side of said furnace.
A bridge-wall, i0, is erected at the rear end of the grate (J, said wall extending across the fire-box and rising above said grate high enough to prevent the fuel, ashes, &c., from falling from the rear end of the grate. This wall also subserves an important purpose in causing the hot air, tiames, gases, smoke, and other products of combustion to impinge against the upper portion of the oven, and thus utilize the heat to the best advantage in cooking.
A line, M, is formed in the furnace, which leads from the rear end of the fire-box around the oven, and thence over the jacket B to the front of the boiler A, as best seen in Fig. 2.
The space between the upper portion of the rear end of the jacketand the adjacent side of the oven \V is closed by a horizontally-arranged diaphragm or partition, 1i), which turns the current of air from the lire-box downward around the oven as it leaves the rear end of the fire-box. There is also ahorizontal diaphragm or partition, 44:, at each side of the main boiler A, which extends from the door P to the rear end of said boiler, and is located about midway between its top and bottom, as shown in Figs. 3 and i. A horizontal diaphragm or partition, 39, is also placed between the front end of the boiler A and door P above the ends of the tines G, said partitions 3!) and 4st preventing the hot air, smoke, gases, and products of combustion passing through the iiue M from rising above the center or lines of the boiler A, and directing them into the smoke-box 83, from whence they pass through the tines G into the smokebox 36, thence over the boiler above the partitions -14. into the chimney K.
The ash-pit door S is provided with a draftregister, 18, and there is also a draft-tine, '1, opening into said pit and provided with a door, 22.
Openings 3.) are formed at each side of the furnace, by which the smoke-box 36 at the rear of the main boiler may be cleared out, said openings being provided with doors to, and beneath said openings there are also openings ($2, provided with doors 03, for clearing out the line M at the bottom and rear of the oven \V. An induction or feed-water pipe, Y, passes through the side wall of the furnace J, and is inserted in the lower portion of the jacket 13, through which water is introduced into the boilers, said pipe being provided with a check-valve, 11- in the usual manner, or with an ordinary stop-cock, as preferred.
In the use of my improvement water is introduced into the jacket or supplemental boiler 13 through the pipe Y by a feed-pump or any other suitable means, from whence it will pass through the circulating or connecting pipes E into the main boiler A. When the jacket is full and there is suliicient water in the main boiler, a lire is started on the grate (,3 in the lire-box 95 and regulated. by the register 18 or door 22. The fire having been s arted, as described, the hot air, flame, smoke, gases, and other products of combustion will pass out of the rear or inner end of the tire-box and impinge against the front wall of the oven \V, by which it will be deflected an d turned downward, passing through the line M around said oven, back over the jacket B into the smoke-box 83, through the tines G into the smoke-box 2m, and thence over the boiler A into the chimney K, in a manner that will be readily understood by all conversant with such matters without a more explicit description. The sides, top, and bottom of the oven \V, being surrounded by the flue M and standing directly in the path of the heated air and products of combustion as they pass from the tire-box 95 to the chimney, will be heated with great rapidity and without any extra expenditure of fuel over what is required for producing steam.
It will be obvious that the boilers are adapted for producing steam for power or heating purposes, and also hot watmfor heating and other purposes; but when used for furnishing hot water for heating it will be understood that the boiler A and pipe 45 are to be entirely filled with water in the usual manner, the pipe being connected with the radiating-pipes and a retin-n-pipe, and the return-pipe connected with the feed-pipe X, such other appliances beingemployed as may be usual or necessary.
Itwill also be obvious that the water-evap" oraiing surface of my improved boiler is largely in excess of ordinary boilers of this character, and that the heat from the tire-box is utilized to the best ad vantage in producing steam and hot water, and also in running the oven 'W.
The connecting or circulating pipes E are made in sections, which are coupled together, and in case it becomes necessary to repair or replace the jacket 13 these pipes may be easily uncoupled and the jacket readily removed through the door P.
I do not confine myself to using the door P, having the doors Q R S, with the specific device herein shown and described, as it is well adapted for any boiler or furnace of this gen eral character. Neither do I confine myself to having the oven open outward through both side walls of the casing or provided with two doors or months; nor to providing two open ings each, 62 and 39, for cleaning out the t1 ue M and smoke-box 36, respectively; nor to the use of two doors, R S, as they may be formed integral or in one; nor to the use of the frame 25, as the door P may be hinged directly to the furnace or casing, if desired; nor to the use of more than one draft-opening for the fire-box. This boiler-front, however, forms no part of the present invention.
Having thus explained my invention, what I claim is- 1. The combination of a furnace-casing, a main boiler therein, a supplemental archshaped boiler disposed within said casing beneath the front portion of said main boiler, one or more circulating-tubes connecting the main boiler with the arch-shaped boiler, a combustion-chamber within the arch of the supplemental boiler, an oven disposed within said casing in rear of the supplemental boiler beneath the rear portion of the main boiler, a flue-space surrounding said oven and opening into the combu'stion-chamber and flue-space around the main boiler, respectively, and a partition extending from the top of the supplemental boiler to the top of the oven, substantially as setforth.
2. The combination of a furnace-casing, a main boiler therein, a supplemental archshaped boiler disposed within said casing beneath the front portion of said main boiler, one or more circulating-tubes connecting the main boiler with the arch-shaped boiler, a colnbustion-chamber within the arch of the supplemental boiler, an oven disposed within said casing in rear of the supplemental boiler beneath the rear portion of the main boiler, a fluespace surrounding said oven and opening into the combustion-chamber and flue-space around the main boiler, respectively, a partition extending from the top of the supplemental boiler to the top of the oven, horizontal partitions between the sides of the main boiler and the casing, and tubular flues within said main boiler, substantially as set forth.
3. The combination of a furnace-casing, a main boiler therein, a supplemental arehshaped boiler disposed within said casing beneath the front portion of said main boiler, one or more circulating-tubes connecting the main boiler with the arch-shaped boiler, a combustion-chamber within the arch of the supplemental boiler, an oven disposed within said casing in rear of the supplemental boiler beneath the rear portion. of the main boiler, a flue-space surrounding said oven and opening into the combustion-chamber and flue-space around the main boiler, respectively, a partition extending from the top of the supplemental boiler to the top of the oven, and a bridge-wall at the rear end of the combustionchamber forming a part of the descending flue at the front of the oven, substantially as set forth.
