3 Claims. (01. 110-91) My present invention relates to furnaces, the serted into the boiler through the customary term furnace being used in a generic sense door opening. The assembled arch is, as shown, to include not only hot air furnaces but hot placed on the fire brick lining 8 and supported water and steam boilers; and, generally stated, thereby with'the margin of the arch spaced from 5 the invention consists of the novel devices, comthe inner wall of the water leg 6 so as to afiord binations of devices and arrangement of parts an annular flamepassage ll. On its under side hereinafter described and defined in the claims. the arch is formed with closely circumferentially Particularly the invention is directed to a spaced radially extended flame channels l5. simple and highly efiicient arch or baflle ar- Preferably, the crown plate iii, of disc-like 10 ranged to divide the flame into a plurality of jets form, is placed on top of the arch and is pro- 10 and spread and direct the same against the invided with an upstanding marginal flange I! that ner or heat transfer walls of the furnace. v assists in directing the flames against the heat The invention is illustrated in the accomtransfer wall of the furnace or boiler. The

This crown plate and 15 Referring to the drawing: its flange may be of cast iron or any other suit- Fig. 1 is a view partly in side elevation and able material. The flre arch or baflle, however, partly in vertical axial section illustrating the should be of a high refractory baked clay or nv n app d a hot at r; ceramic material. However, the arch might in 2 is a bottom P View 01 he a c resome instances be made of cast metal or like ma- 20 moved from the boiler or furnace; terial.
Fi 3 is an edge elevation of the arch or bame- In action the flame from the oil burner will illus rated n n produce the initial combustion in the chamber Fi 4 is a plan w of the cr wn plate as H! below the flre arch. This flame will, as preferably placed on top of the arch proper. t t d, b djyided into a multiplicity of jets or The f me-0 in the nature of a hot streams and directed against the inner or heat boiler, is indicated as an entirety by the numeral transfer ll' of the furnace, thus preventing 5. T s furnace P p e the customary 1 the flames from centralizing at the axis of the rounding Water 8 5, the Inner Wall of which is furnace. Moreover, the arch will be heated to a exposed to the interior of the furnace and acts very high temperature so that the somewhat as a heat transfer Y incompletely burned fuel from the chamber l2 The boiler 5 rests upon the customary shell or Wlll be brought agalnst the very hot f s base 7 which as shown, is lined by fire brick 8 of the arch and the completion of combustion to form a combustion chamber.

In carcaused to make the major portion of its 'that the heat transfer; chamber is of greater diameter than the combustion chamber, and to accomplish this in standard furnaces 'or. boilers.v
' it is often necessary to reduce the diameter of moke. r s Teshhng 900110313? Y the combustion chamber to the desired diameter g A preferred f of the device has been lllus- 5o by bricking up the combustion chamberto the tratedin the -w e. but it Will be, u de stood desired diameter. that the same is capable of various modifications The arch or batlie is 'of disc-like form-and is withinthe-scope of the invention herein disclosed preferably made of two semi-circular sections and claimed. a 56 ii, which sections separately may be readilyqin- The device above described has been put into .In this wa y maximum heating efliciency, com
plete combustion f of thefuel, and elimination actual use, thoroughly tested, and found highly efficient for the purposes had in view. I
The invention herein described is illustrated as applied to a cylindrical furnace or boiler and has been found in practice to be highly efllcient in that connection, but it will, of course, be
understood that the arch or baille may be applied 7 in square or angular furnaces or boilers and will be efiicient also in such use.
What I claim is: v
1. In a furnace, a heat transfer chamber surrounded'by heat transfer walls, a combustion chamber below the heat transfer chamber and I having surrounding refractory walls,'said combustion chamber being of less internal area than that of the heat transfer chamber and providing a'marginal ledge adjacent the lower edge the surrounding space thereabove defined by the outer edge of the baiiie and walls of the heat transfer chamber.
2. The structuredeflned in claim '1, in which the plate-like baflle member is further provided with a marginal flange upstanding therefrom in spaced relation to the walls of the heat transfer chamber, whereby to confine and direct the gases expanding through the combustion channels of the baiiie member for a material distance above the upper surface of said baiiie.
3. The structure defined in claim 1, in which the under-central portion of said plate-like baffle member is concaved to points adjacent the inner ends of said marginal series of radially extending, outwardly and upwardly flaring combustion channels, whereby to effect uniform distribution of the burning gases from the combustion chamber to said channels.
