From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

1. In a furnace having an ash pit, a water tank in the ash pit, means for supplying and withdrawing Water from the tank, a tray supporting frame rotatably mounted in the tank, a tray in the frame, and means connected to the frame and accessible exteriorly of the ash pit for rotating the tray and frame in the tank to wash dirt and fine ashes from the tray into the tank after each dumping of the furnace.

2. In a furnace having an ash pit, a funnel in the top of the ash pit, a water tank below the funnel, means for supplying and removing water from the tank, a frame rotatably mounted in the tank below the funnel, a tray removably supported in the frame in registration with the funnel and adapted to receive ashes therefrom when the furnace is dumped, a stub shaft rising from the frame, a shaft geared to the stub shaft and extending exteriorly of the ash pit, and means on the last named shaft for rotating the shaft to rotate the tray and frame in the tank for washing dirt and fine ashes into the tank after the furnace is dumped.

3. In a furnace having an ash pit, a tank in the bottom of the ash pit, valve controlled pipes entering the ash pit and the tank for supplying the tank with water and draining water from the tank, said tank being substantially circular in contour and having a central bearing recess in the top face of the bottom, a tray supporting frame having a depending gudgeon fitting in said bearing recess and rotatably mounting the frame in the tank, a stand shaft on the frame, a shaft geared to the stand shaft and projecting exteriorly of the ash pit, means on the last named shaft for rotating the shaft, a funnel secured to the top of the ash pit, a tray in the frame having a reticulate bottom, the tray and the funnel being of substantially the same shape so that When the ashes are dumped the ashes will be deposited in the tray, and means at the ends of the frame permitting of the tray being Withdrawn endwise through the frame and the ash pit door.
