SPECIFICATION forming part of Letters Patent No. 270,127, dated January 2, 1883.
Application filed June23,1882. (No model.)
T 0 all whom it may concern:
Be it known that I, DAVID W. ROBB, of An1- herst, Nova Seotia, Canada, have inventeda ,new and useful Improvement in Heating-Furnaces,- of which the following is a full, clear, and exact description.
-The object of my invention is to provide a sufficientquantity of air to the fuel, and to prevent a hinderance of the draft by the formation of clinkers. r
The invention consists in a lining for a fireot formed of a series of sections provided with ribs forming downwardly projecting prongs which are curved inward, which sections are hung by suitable books on internal flanges of the fire-pot.
The invention further consists in the coinbinntion, with the grate, of flanged wheels which run on rails below the grate, which rails have lateral curvatures, which are also curved upward, all as will be fully described and set forth herei-nalter. a
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. Figure l isa cross-sectional perspective view of a fire-pot provided with myimproved lining and grate. Fig. 2 isade-tail plan view of the same. Fig. 3 is a detail perspective view of one of the lining-sections.
Thefire-pot A is provided with inwardly-projectingangular hook-projections or flanges B and U at the bottom and middle of the height of the fire-pot, respectively. The lining of the firepot is formed of a series of sections, 1), each provided on the rear side with a hookprojection, E, for catching on the upper annular flange, U. One or more longitudinal ribs, F, projects from the rear side of each section D, and these ribs project below the lower edgeof the sections D, and thusform a selies of prongs, F, which have the lower parts of the inner surfaces curved inwar dthat is, toward the center of the bottom of the firepot-so that the lower part of the inner surface of the lining of the fire-pot will converge toward the center of the fire-pot, as is shown in Fig. 1. As the outer edges of the ribs F are carried straight down, the width of the lower ends of the prongs will be much greater than the width of the ribs. Each prong is Each section l) of the lining is provided Witha series of apertures, G, to permit air to pass 7 into the upper layers of fuel in the fire-pot.
The lining of the fire-pot forms a kind of basket, the lower inwardly-projectin g prongs, F, of which hold the fuel in place.
The grate H is provided with two opposite pivots, I, on which flanged wheels J are loosely mounted, which wheels rest on longitudinal rails K in the ash box L. These rails are each provided with a segmental outward curve, M, at the sides of the bottom of the fire-pot, which curves are directly opposite each other.
At the laterally-curved parts these rails also have an upward curve, N. The grate is provided with a suitable handle, 0, projecting from the end of the ash box, which handle can be operated by a suitable lever or grateshaker. The front ends, K, of the rails Kare bent upward to prevent drawing the wheels J 0d the rails, and the rear end of the fire-pot is provided with a cheek-projection, P, to preventpushing the grate too far back under the fire-pot. v p
The operation is as follows: By providing the sections of the lining with the ribs F airspaces will be formed between the lining and the fire-pot. The air can pass through the slots between the prongs F into the fuel, and air can pass through these apertures G to the upper part of the fuel, which air mingles with the heated gases. Furtherinore,a circulation of air is kept up between the lining andthe shellor fire-pot, whereby the lining Will be preserved. The ribs F strengthen the linings and prevent warping of the same,
The grateH can be rotated in the horizontal plane by means of the handle 0, the wheels running on thecurves M,and at the same time the grate is worked up and down, as the track is also curved upward at N. This shakes the grate throughly and agitates the fuel, so that all the ashes, cinders, 850., will drop through it.
The grate can be drawn forward on the rails Kfor the purpose of removing the, clinkers from the grate. The fuel is retained in the fire-pot by the inwardly-curved lower ends of the prongs F.
Having thus fully described my invention,
IOO
I claim as new and desire to secure by Letters Patent- 1. The combination, with the fire-pot'A,
1 provided with the inwardly-projecting annular flangesB G, of the lining-sections D, provided with hook-projections E, and with ribs F, having the lower ends curved inward, and
having notches a in the lowerends ofthe outer edges, substantially as herein shown and described, and for the purpose set forth.
2. The combination, with the fire-pot A and the grate H, of the flanged wheels J, mounted on the grate, and the rails K, substantially as herein shown and described, and for the purpose set forth.
3. The combination, with the fire-pot A and the grate 11,01? the flanged wheels J, mounted on the grate, and the rails K, provided with lateral curvatures M, substantially as herein,
shown and described, and for the purpose set 20.
lateral curvatures M, which are also curved 25 upward, substantially as herein shown and described, and for the purpose set forth.
