Abstract
Abstract This invention consists of a device for automatic fish feeding, and lighting of aquariums. It consists of a plate which fits over the top of an aquarium. On its top the plate is equipped with a timer, the rotating face of which is provided at its rim with a rod extending at right-angles from said face, for a single feeding per day, or with two equally spaced rods for a double feeding per day. The said rods can also be attached to the "ON" tab of the timer. The rods engage a circular turntable in which are radially located consecutive pivoted scoops, which contain fish food, causing said container to rotate in a horizontal plane. A hole is provided in the plate under the path of the scoops so that when a scoop arrives over said hole, its open front end drops through said hole discharging the food into the water. The plate is also provided with slots for the passage of light into the aquarium; and an opening for manual feeding.
