Application led December 23, 1897. Serial No. 663,135. (No model.)

To all whom t may concern: are indicated by the same reference-figures, Beit known that we, JOHN THOMAS WOOD and in the case of sections the direction in and JOHN ALEXANDER BRODIE, subjects of which they are viewed is indicated by the the Queen of Great Britain and Ireland, resmall arrows placed adjacent to the letters 55 5 siding at Liverpool, in the county of Lancasdenoting the plane of section.

With the arrangement described if it bedesired to pass the hot gases directly from the adjacent des! ructor-cells to the steam-generator the dam pers 15 and 12 are placed in the positions indicated in full lines in Figs. Band 4. The gases then flow through the passages 3, circulate around the heating-surfaces of the steam-generator, are cooled thereby, and then pass through the passage 16 to the comlnon large cold flue 17, where the velocit)1 is so reduced that any dust remaining iu suspension is deposited before the gases finally pass out of the chimney.

If it be desired to put the steam-generator out of action, it is only necessary to keep the damper 12 closed and to turn the dampers 15 into the position shown in dotted lines in Fig. 4. The gases from the adjacent destructorcells, if they be in action, then pass down the passages 14 lo the common hot. flue 10 and are available for heating some of the remaining generators, If it be desired to heatthe steamgenerator from some of the cells other than those adjacent-to it, the dainpers 15 are turned into the positions shown in dotted lines, and the corresponding damper l2 is opened. The hot gases thenV fiow from the holl flue 10 into the space 9 up the passages 13 and over the fire-grate 5 into the furnace 4, the defiectors 18 being provided to bring the gases into intimate contact with the fuel on the dre-grate. From the furnace t the gases pass, as before, to the common cold iiue 17 through the passage 17.

It will be seen that the arrangement of the common hot flue and passages enables any generator to be put out of action, the hot gases from its corresponding cells then entering the common hot flue and so being distributed among the remaining steam-generators. In the same Way any individual cell may be taken out of action for repair, cleaning, or other purpose.

The independent furnaces'lt may be kept in action contin nously or as circumstances dictate. They serve the double purpose of acting as fume-cremators and as sources of heat independent of or auxiliary to that of the destructor-cells.

The arrangement of the alternate generators, as 1b, with their furnaces 4, passages 3, 9, 11, 13, and 14 and hot flue 10 is, as already stated, symmetrically similar to that already described, the corresponding parts, where shown, beingindicated by corresponding reference-gures with dashes appended.

19 is a space between the backs of the destructor-cells, which is found to be of great service for the inspection of the tubes of the generators and for the4 removal of the fine dust deposited below the tubes. It is also useful when the mechanism for operating the tire-bars of the cells requires to be at the back thereof and for enabling the steam-jets used in connection with the air-supply of the cells to be fitted at the back of the cells instead of the front thereof, where they are objectionable on account of the hissing noise they produce. l

The chargngplatform 20 is placed laterally above v the cells, and the storage and charging trucks 2l and charging-holes 22 are arranged in accordance with the said other specification hereinbefore referred to, so that the refuse can be tipped from a cart 23 into the trucks and transferred into the destructorcells` with a minimum of labor.

Although theiuvention has been described with respect to a set of double or back-tobacl; destructor-cells, it is clear that it may with equal facility be adapted toa set of single cells, in which case only a single common hot flue is required.

We are aware that combined refuse-destructor cells and steam-generatorshave been used prior to our present invention, and, further, that auxiliary furnaces have been fitted to the steam-generators, the said furnaces being adapted to serve also as fume-cremators, and to such broadly we make no claim.
