Specification of Letter; Patent.
Patented A r. 13, 1915.
. Application filed August 4, 1911. SerialNo. 642,359.
In the patent issued to me- December 29,
1908, No. 908,228, means for affording circulation within the base are shown, and in the present instance I provide air conducting devices for supporting the grate bars and other portions of the structure and for admitting air from the base to air tubes on the sides of the fire pot and attached to or formed integrally with the boiler sections. I may also, if desired, provide air conducting devices below the front section of the furnace, at the grate level,'and designed to admit air from the base to an air space within the said front section, and so arranged that the aforesaid devices assist in supporting the front section.
In the accompanying drawings forming part of this application, Figure l is a perspective view of a portion of the furnace structure, with parts broken away. Fig. 2 is a top plan view of two of the air conducting devices which are also employed as grate bar supporting means. Fig. 3 is an elevation of the devices shown in Fig. 2. Fig. 4, is an end view thereof. Fig. 5 is an enlarged view in vertical section on line 5-5 of Fig. 1 showing one of the air conducting devices located below the front section or wall of the furnace. Fig. 6 is. a section on the line 66 of Fig. 7. Fig. 7 is a section on the line 77 of Fig. 6.
In carrying out my invention, I make use of a hollow base portion 10, above which the boiler sections are mounted, the sections 15 at the rear of the fire pot having a series of vertically arranged hollow members or pipes 16 connecting the lower transverse pipes 17 with the upper transverse pipes 18. The fire pot sections 19 are substantially U shaped and have no intervening vertical pipes between those constituting the sides. The rear boiler section may have an enlarged pipe or chamber atits upper portion, as at 21, and a lower transverse pipe 22,.an opening 23 being provided for the escape G. ENGELHART,
of the products of combustion. The front section 25 of the structure has an upper charriber 26, similar to water chamber 21, and a lower transverse pipe 27, providing an opening 29 closed by door 29. A clinker door 30 and a door 31 opening into the base are oocated as shown in Fig. 1. Each of the vert cal pipes of the section immediately at the wear of'the fire pot is provided with a baffle plate 35, reducingthe air space between thelower portions of these vertical p'ip'es and'directing the currents of heated air and gases upwardly before they pass,
downwardly in order to escape through the opening in the rear section of the boiler. Air tubes 37 are located alongside of the baflie plates and convey air from the hollow base to the fire pot and discharge over and into the mass of burning fuel. The tubes are provided with elongated openings 38 as shown. At the rear of the fire box is a stationary grate member 41 and between the latter and the stationary grate members at the front of the fire box (described below.) are the movable grate bars 42, the lat r being provided with trunnions 43 supported in sockets formed on the edgesofthe devices 44. The devices last merltioned constitute an importantpart of the structure here described and serve to support the grate bars and to provide means for admitting air from the base 10 to the vertical air tubes 45 on the inner walls of fire pot sections 19. The gratebar su1,--.rts include box-like members 46 which as; secured by bolts 47 passing throughthe downwardly projecting members or plates 48 and through a'portion 49 of the base. Thesockets for the trunnions 43 are indicated b 50, onehalf of each socket being formed in the free corners of each supporting device 44. The front face of the latter is formed as at 44'. A supportingdevice similarly formed may be used below the front section ofthe fur; nace.
Referring to Fig. 5 which is' a section on line 55 of Fig. 1, it will be noted that the front section has an air space 51 in the rear of the water space or chamber 52, space 51 communicating with the interior of the fire .pot by means of openings 53. One of these spaces is located on each side of the door 30. Ribs "54 are formed on the wall between openings 5.3 and serve to keep the fuel from obstructing the passage of a1r.
It will be observed that the inner walls 55 and '56 of those stationary devices 44 which are used below the front furnace section are substantially on a line with the walls 57 and 58 of'the air chamber of the front section, the latter being supported largely on de' vices 44: but in part also on base 10.
Particular attention is directed to the effective means for distributing the air about the fire pot and the fuel therein, and for directing the heated gases rearwardly from the fire pot'bet'ween the Vertical pipes of the boiler sections there located.
What I claim as new and desire to secure by Letters Patent is:
v Ina device of the class described, a furnace structure including a fire box, one wall of which comprises an upper hollow portion and a-lower hollow portion of less thickness 1 than the upper portion, a stationary grate, -20
member having an air conducting space conportions.
In testimony whereoi afiix my signature in presence of two witnesses.
