JOSEPH MONVILLE AND MARKROBERTS, OF HUBBELL, MICHIGAN.
STEAM-BOILER FURNACE.
Specification of Letters Patent.
Patented June 5, 1906.
Application filed June 13,1905- Serial NO- 265,079.
T0 at whom it may concern.-
Be it known that we, JosnPH MONVILLE and MARK ROBERTS, citizens of the United States, residing at Hubbell, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Steam-Boiler. Furnaces, of which the following is a specification.
This invention embodies an improved furnace for steam-boilers of that type in which the smoke and products of combustion after being conveyed to the end of the furnace remote from the fire-box are returned through the fines in the boiler, the object being to increase the heating capacity of the furnace to the greatest degree practicable.
The invention in this instance resides particularly in the special construction of the furnace and boiler whereby the heating capacity of the furnace is increased to the maximum and whereby a cheaper and more serviceable structure of both furnace and boiler is produced.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a side elevation of a furnace embodying the invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is an end view, the chimney not being shown. Fig. 4 is a view of the end of the furnace opposite that shown in Fig 3.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
In the drawings the numeral 1 designates the boiler, which is of a construction substantially the same as many of those at present in use. The furnace 2 comprises a firebox 3, and the backof the fire-box is provided With an opening 4. The combustionchamber of the fire-box 3 is arranged below one end of the boiler 1, and the opening lestablishes communication between the firebox and a smoke-flue 5, which extends therefrom the entire remaining length of the boiler. The smoke-flue 5 consists of a shell 6, which is of somewhat semicircular form in crosssection, having its upper portions attached to opposite sides of the boiler, as shown most clearly in Fig. 1 of the drawings. The shell 6 is secured at one end of the fire-box structively,
ture and is of course spaced at its lower portionfr'om the bottom of the boiler 1 to form the flue 5, before mentioned. As will best be seen by reference to Fig. 2, the flue 5 tapers from the fire-box 3 toward the rear end of the boiler, where its small or contracted end opens into a vertical smoke-box 9 at the rear end of the boiler, said smoke-box 9 extending above the flue 5 into communication with the rear end of the return-fiues 1 0, located within the boiler 1, and also extending below the flue 5, as illustrated in said figure. The bottom of the shell 6 in the flue 5 is provided, preferably, with a brick lining 7. Suitable rests or standards 8 support the shell 6 and the portion of the boiler 1 above the same. The smokeflue 5, being just below the boiler 1, is so arranged that the heat of the smoke and products of combustion passing through said flue 5 Will be received by the lower portion of the boiler in an evident manner, and as the boiler is exposed directly to the influence of said heat the same will be more effectively heated than would otherwise be the case. In other words, the round form of the lower portion of the boiler 1, which portion forms virtually the upper side of the flue 5, gives a maximum amount of heating-surface, which may be heated by the smoke and products of combustion passing through the flue 5, at the same time accomplishing economy of space and material. The smoke-flue 5 leads into the smoke-box 9, arranged at the end of the boiler 1 opposite that adjacent which the fire-box 3 is located. The flue 5 communicates with the box 9 between the upper and lower ends thereof, and said box is attached directly to the rear end of the boiler 1, so that the smoke and products of combustion passing through the flue 5 will pass from the box 9 directly into the usual flues or pipes 10, arranged in steam-boilers of this type. The smoke and products of combustion will thus return the entire length of the boiler 1 interiorly thereof through the flues 1 0 and after having traversed the length of said boiler beneath the same passing through the flue 5. The advantages for the arrangement as shownare obvious and therefore need not be specifically described. A chimney 11 is provided for the furnace 2 and leads from the boiler 1 at the end opposite the smoke-box 9. Suitable steam and safety valves 12 and 13, respecare provided for the boiler, and manholes 14 in the top of the boiler and 15 at the end thereof are provided. The fire-box has the fire-doors 16 and the cleaning-out doors 17, as shown most clearly in Fig. 3 of the drawings. Flue-doors 18 are provided upon the outer side of the smoke-box 9, and a door 19 is disposed at the lower portion of the same to facilitate removal of soot or ashes or the like.
As shown in Fig. 2 of the drawings, the fire-box 3 is provided with a water-leg which extends upwardly on both sides of the circular shell of the boiler and is provided where it partially surrounds the side shell with vertically and horizontally extending series of openings 20, which establish communication between the interior of the boiler-shell and the water leg. The arrangement of apertures 20 leaves sufficient solid material remaining to avoid any weakening of the structure.
Having thus described the invention, what is claimed as new is A steam-boiler furnace, comprising a horizontally disposed boiler proper provided with a series of return-Hues opening into it at one end and out of it at the other and provided at its front end with a chimney and fire-box 3 underneath the front end of the boiler proper and provided with awater-leg extending up on each side of the boiler at the front end thereof and provided with a vertically and horizontally extending series of openings establishing communication between the water-leg and the interior of the boiler, a tapered flue composed by a slanting shell 6 having a brick lining 7 and extending underneath the boiler, and a vertical smoke-box in communication with the rear contracted end of the said flue, the upper end of said smoke-box being in communication with the rear end of the boiler, as and for the purpose set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
