Flour Bin and Sifter. (open access)

Flour Bin and Sifter.

Patent for a flour bin and sifter that improves on a patent that was previously granted to the inventor (No. 411,671). The improvements improve "in an adjustable attachment to the bin whereby said bin may be easily and adjustable attached to a wall; a cut-off inserted near the base of the bin to regulate the flow of material into the sifter; a scraper adapted to scrape the upper side of the cut-off so that no material can be drawn out with said cut-off; in having the sifter connected to the base of the bin by single instead of double pins, and in a single door hinged to the front face of the sifter, and so closely hinged that when the same is open no dust can fly out in the face of the operator" (lines 20-33).
