HERBERT MCELROY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALFTO FRANKLIN LAWRENCE, OF SAME PLACE.
FURNACE FOR STAMBOILERS.
SPECIFICATIQN forming part of Letters Patent No..241,392, dated May 10, 1881.
Application filed January 25, 1881.
T o all whom 'it may concern:
Be it known that I, HERBERT MCELROY, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Furnaces for Steam- Boilers, of which the following is a specifica tion.
My invention relates to that class of furnaces in which the fuel is automatically fed from a hopper through an inclined chute, and mainly consists in the combination ofan inclined plate which forms the front of the chute, and is bolted at its upper edge to the front plate of the furnace in such a manner as to hold it in connection' therewith and admit of the adjustment of its lower edge to give any desired inclination to the plate as may be found appropriate to the feeding operation, the plate being provided with an adjustable inclined grate at its lower edge, and the adjustment of the plate and grate being separately effected by means hereinafter described.
In-the accompanying drawings, which make a part of this specification, Figure 1 is a front elevation of my improved furnace. Fig. 2 is a vertical section at the broken line .r .fr of Fig. l. Fig. 3, Sheet No. 2, is a perspective view of the adjustable plate H when provided with a drop-grate, l.
Like letters of reference in all the figures indica te the same parts.
AArepresent the side walls of my improved furnace, and B the front of the furnace, having a front plate7 B'. C is the bridge-wall, and D the arch. Eis the combustion-chamber, and F the grate which forms its bottom. The arch D has an upward inclination from its rear to the mouth ofthe inclinedchute G, as seen in Fig. 2 and at its upper part forms the rear side of said chute. rlhe front of the chute is formed by the inclined plate H, which is hung at its upper edge by means of the bolt c, which is passed thron gh the front wall of the furnace and has a nut on its outer end. The plate is corrugated, with the corrugations ruiming up and down to facilitate the automatic feeding of the fuel, as seen in Fig. 3. Itis adjustable at its lower end to bringit to an y desirable angle that may benecessary to the proper auto- (No model.)
matic feeding of the fuel to the combustionchamber by means of the rod J having bent ends, one of which is connected with the eye c on the inside of the plate B', and the other with the perforated arm K, having the perforations close enough to each other for bringing the plate into any desired position., The plate has a frame, H', connected by means of bolts at its lower end, in which is hung the inclined grate seen in detail in Fig. 3. The grate is adjustable by means of the rod J', the eye c' counected with the front plate, B', and the arm K' connected with the grate, the said arm having perforations for changing the connection of the rod K', whereby to vary the angular position of the grate as may be found necessary to regulate the feeding of the fuel.
L L are the ash-pit doors, and L' L" and L2 L2 doors of the upper part of the furnace. L3 L3 are doors for opening and closing t-he airflues M M at the lower part of the side walls, A A, and connecting with the air-chamber N of the bridge-wall C, having an outlet-passage, d. L4 L4 are doors for opening and closing the airfiiues M' M' at the upper part of said walls, and connected at their rear ends with the air-chamber N' at the rear part of the arch D, having an outlet-passage, d'. rlhe air in its passage through said ilues and chambers becomes highly heated, and in passing out of the passages d and d' commingles with the products of combustion as they pass through the outlet d2 of the combustion-chamber, whereby to complete the combustion. The doors L3L3 and L4 L4 are connected with the front plate, B, bymeans of the rabbeted ways O O an d O O, and are adapted to slide up and down, having a spring which bears against the front plate, B', the force of the spring being regulated by means of the screw e.
R is a hopper, connected at the top of the furnace with the mouth of the inclined chtite G. lt is provided with a case, R', to form the space f, to prevent the outward radiation of heat. There is an opening, g, through the front of the hopper and the case to admit of the pas sage and use of a slice-bar for loosening the fuel in the chute Gr when it becomes too much packed to admit of its automatic feeding into lthe combustion-chamber.
IOO
S is a door for closing the opening when the I claim as my inventionslice-bar is not used. The hopper is also prol. The combination, with a furnace having vided with a hinged cover, T, to prevent the a feedinghopper and an inclined chute, of the upward escape ot' heat from the combustionswinging grate I and the adjustable plate H,
5 chamber through the chute G. The hopper substantially as described. zo
would be used especially when shavings or like 2. Afurnace having` an inclined ue, Gr, hopfuel are burned,and maybeomitted,if desired, per It, adjustable inclined plate H, provided when coal is burned. In this latter case I emwith au adjustable inclined grate, I, and havploy the hinged plateU forcovering,` the mouth in g air-tlues M M and M M', substantially as 1o of the chute to prevent the upward escape of and for the purpose set forth.
heat the plate being folded down when not so used, upon the top plate, V, towhich it is HERBERT MCELROY' hinged, as seen in Fig. 2. Witnesses:
If desired, the case R ot the hopper may be THOMAS J. BEWLEY,
15 omitted. WM. LANGDON.
