3337. Comings, W. R. Feb. 14. Content, sdelivering and withdrawing.-Boxes for distributing powdered or pulverized materials are provided with one or more false lids or diaphragms under the perforated lid and adjustable in distance therefrom. The perforated lid B, Fig. 1, has a spike D, which protrudes through a hole in the diaphragm G and serves to break up or divert lumps. The receptacle may be used as a pourer when the lid B is removed. A flat spring or hinged division-plate or baffler may be used between the diaphragm and the top, as shown in Fig. 6, so that the material passes through a series of holes decreasing in size. With a rectangular receptacle, there may be two or more spikes, and the flow is regulated by pushing the lid up or down a scale marked on the box. The diaphragm may be dished to allow material left in the distributing space to pass readily back into the box.
