Abstract

273,038. Roberts, J. A.., and United Alkali Co., Ltd. April 9, 1926. Filling granular, pulveralent, or like materials into canisters, bottles, cartons, and like containers.-A rotary plate 1, Fig. 1, carries a number of rubber or like funnels 4 projecting from the underside and registering with carriers 5 mounted on brackets 7 rotating with the plate 1. In use, a receptacle 6 is pushed from a conveyer by a radially movable member 26, Fig. 2, into engagement with a centering device so that the receptacle and the funnel 4 are concentric, a spring 29 ensuring positioning. The carriers 5, which have been depressed against the action of springs 9 by a fixed rail 23, now rise and press the receptacles against the undersides of the funnels so that the latter project slightly into the interior. The container is next carried beneath a hopper 12 from which the material falls through the funnel into the receptacle. The hopper has no cut-off device but is normally closed by the plate 1. A scraper 15 surrounds the lower end of the hopper to prevent material from being carried round by the plate. Should any escape from the scraper, it is directed by scrapers 16, 17 to a. position on the plate from which it is collected by a scraper 18 and re-delivered to the scraper 15. A vent pipe 14 allows the escape of air displaced during the filling of the receptacle. A serrated portion 22 of the rail 23 imparts vibrations to the rollers 20 on the carrier and causes the material to settle in the receptacles. The carriers 5 are depressed and a radially-acting member 24 removes the filled receptacle on to a delivery channel 25. The material in the funnel falls into the receptacle when the carrier 5 is lowered. A sleeve 13 at the lower end of the hopper is vertically adjustable to control the flow of the material to the plate.
