Abstract: 353,623. Refuse-burning stoves; atmospheric gas burners. KLEIN, H., 927, Oakdale Avenue, Chicago, U.S.A. June 6, 1930, No. 17637. [Classes 75 (i) and 126.] A domestic incinerator having a gas-burning grate for consuming the refuse comprises a grate of inverted V-form, pivotally mounted for dumping purposes in a shoot at the lower end of the fire-pot, the grate having interconnected conduits to which gaseous mixture is supplied through a hollow trunnion and gas discharge orifices extending from the conduits near the periphery of the grate and also around openings provided in the grate between the conduits. The incinerator shown comprises a fire-pot B with sloping walls, removably supported on lugs 11 secured to the outer casing 1. An inner drum C is removably supported on the fire-pot, its upper end being held in spaced relation to the top of the stove by depending clips 19, so that gases passing up the space 12a between the drum and outer casing may reach the outlet flue 3a. The fire-pot, which is provided with internal ribs 14, carries a hollow member F with internal baffles 40, extending diametrically across it and serving as a central division member and flue, into the open lower end of which pass some of the flames from the gas grate, subsequently to pass into the refuse through openings 39, 39a in the walls of the member. The gas grate D is tiltably mounted on trunnions D<1>, D2 and extends across, and normally closes, the discharge shoot B<1> of the fire-pot. The trunnions are journalled in the casing 1 of the stove, D<1> being hollow for the supply of gaseous mixture to the grate, and D<2> having pivoted to it a handle 34 for tilting the grate. A spring 36 normally causes a lug 34a on the handle to engage stops 32b to retain the grate in its normal position, shown in full lines in Fig. 6. When dumping, the grate is rotated to a position, shown in broken lines, in which one side of the shoot B<1> is obstructed by a horizontal wing of the grate, the other being opened. The grate, which is of a ridge or inverted V-formation, comprises a hollow ridge portion 20 forming a conduit 20a, to which gaseous mixture passes from the integral trunnion D<1>, and wings 21 sloping downwardly from the ridge, which are formed to provide conduits 21a near their lower edges and conduits 21b adjacent their ends, the latter connecting the conduits 20a, 21a. An opening 28 extends across each wing between the conduits 20a, 21a. The ridge 20 is provided with lateral and end burner openings 22, 22a respectively, together with intermediate openings 22c beneath a narrow rib 22b and openings 24 guarded by overhanging lips 24a. The conduits 21a are provided with lateral burner openings 25a, and the conduits 21b with openings 25b at the ends of the grate. A crown plate 23 projects over and protects the openings 22c, and is formed with curved and extended end portions 23a which similarly protect the orifices 22. Each wing has secured to it a plate 26 protecting the openings 25a and having upwardly extending ends 26a to protect the openings 25b. Ribs 27 are formed on the wings 21 extending down from the central ridge, across the openings 28, to the outer edges of the wings. The ribs are interrupted to accommodate the plates 26, which are formed with ribs 26b in alignment with them. A " timostat " 31 turns the gas on and off at periodic intervals.
