.1. In an incinerator having a floor, a charging door above said floor adapted to charge the; material to be burned onto the center of the fioor of the furnace chamber and a stoking ram at the center of said floor, in combination wlth means adapted'to raise said ram to distribute the charge over: said floor;
ing afloor, a charging door above saidfloor adapted to pile upon the floor the material to be burned, and a ram in said floor in vertical alignmentwith said door, and the top of said ram normally completing said floor, in combination with means adapted to force said ram upward to distribute over said floor the material .to be burned.
3. In an incinerator having a floor a charging door adapted to charge onto the floor .the'material to be burned, and a ram in saidfloor, in vertical alignment With said door,'said ram having acone pointing upward; the base of the cone being normally level with said floor, in combination With means adapted to raise said ram to carry the base of the cone above the floor; I
