1319637 Fish feed dispenser J RACK 13 Aug 1970 [20 Sept 1969] 39112/70 Heading A1A In a fish food dispenser, a funnel shaped portion 1a of hopper has its lower aperture 1b normally blocked by a pivotably suspended skittle shaped blocking member 7, which is connected to a pendulum 14. A tapering protective tube 16 encircles the blocking member and part of the pendulum. A predetermined amount of feed is dispensed when a fish displaces the pendulum and thus the blocking member. The blocking member 7 may be made of rubber, wood or light metal, the protective tube of plastics and the hopper funnel shaped portion of polythene, polystyrene or PVC, with the hopper itself of transparent or translucent plastics. |
