This ash can has steel rockers on the bottom with lettering saying “Banner Dustless Rocker Sifter.” Inside there is a sifting tray with a wire screen bottom. The lid of the ash can says “eliminates dusty backbreaking shaking. The large sifter tray permits the ashes to sift freely. All weight is carried by the stamped steel rockers.”
Ash was dropped in the can and what fell through was used again on the sidewalks in the winter, for compost, or to help fertilize the garden. Whatever big chunks remained on top were either thrown away to re-used.
