In starting the tire and when' it is desi-red to cause-the f uel to burn more freely the ring is vt-u'rnedtoelose the apertures 59, thereby causing all of the air to lugs 8() preferably'formed integrally with the ring 58, The forward ends of the bars are supported by detachable members 81 to facilitate readily removing the same when necessary. To this end a pair of depending brackets 82 are formed onthe ring one being provided for each pair ot' grate bars and the members 81 are detaehably secured thereto by bolts 83. The members 81 each comprises a straight horizontal portion 84 and a pair of bearings 85 formed at the ends To maintain the grate bars in the bearings 85 depenl are formed on'the ring 58 in 'i' of the brackets 82. See Figs. 1 and 6. Fixed to the grate bars and arranged between the brackets 82 and lugs 86 are inteimeshlng gears 87, that is the gears of' each palr of grate bars intermesh,

about the re `pot` but one pair is ar- .ranged slightly in advance of the other pair of gears in order that the tire on one side may be shaken down wit-hout disturbing the fire on the other side. The-two inner grate bars are extended forwardly and squared as at 88 to receive the shaker. When shaking down the re the ring 73 is turned until its apertures 74 regster'with the apertures 59. The dust and ashes then pass upwardly through said apertures7 the passage way 67, the combustion chamber 16 to the smoke or flue chamber and flue;

esmas y and partially surrounding the fuel magazine is a hollow cast-ing v105 forming` the boiler yof a Water heater when it is desired to use the furnace as a combiuatiouhot air and hot 3,06 indicates the pipes leadingt and from the member No, The mehr be'r 105 is substantially semi-circular or horse shoe shape and is arranged where it will receive a great amount or' heat from the kfire and yet is removed from the lire not so that cold Water therein will not deuden the fire. l

The jacket U is provided Witha cold air duct or inlet 107 and vits upper end is provided with the het air pipes 108 leading to I, the several rooms of the buildingn The furnace above described is of great heating capacity in proportion to its size and the amount of fuel consumed. This obvious when 'the great radiating surfaces of the drum,v the drum' head, the smoke pipes and the flue chamber are taken into consideration. The cold air entering the furnace through the inletl 107 passes upwardly between the Vanesl() to the top of the drum and: there art of the air passes onl upwardiy between Le varies` 22 on the smoke tubes While part of the air passes in' between the l'drum head and the bottom of the smoke or flue chamber. `The large size of the combustion chamber alsogives ample opportunity for comparatively all of the products of combustion to be consumed. before passing into 'the Hue, thus obtaining a large percentage of heat from the fuel.

The simplicity of the furnace andthe comi paratively low cost at which the same may be manufactured and set up shouldrbe noted'. The' Whole furnace is composed of castings as they come direct from the foundry, no

tooling or jointing being required with the exception of the holes for the' hinge pins the doors. It is assembled by merely building or laying one part upon the other in order and the only bolts or other fstenings required are those for the members 81 which support the 'forward ends of the grate bars.

Nand the bolts and fastenings for securing the front frame and the front in position.
