  • Patent number: 5222461
    Abstract: An animal activated feeder (10) has a base (11) which supports a central cradle (17) for rotation about a central axis. A circular food bowl (40) having a number of receptacles (41) can be positioned on the cradle (17) to rotate with it, or lifted off for cleaning. The base (11) includes a central spring housing (13) having a flat helical torsion spring (14) ("clock spring") which causes rotation of the cradle (17) and therefore the food bowl (40), but rotation is indexed in increments by a pet activated foot pedal (29) which is pivoted to the base and has a finger (28) lying in the path of travel of lugs (25) of a first group which project from the cradle (17). Indexing is limited to feed one receptacle (41) at a time, preventing spinning of the food bowl, by a second group of lugs (24) projecting from the cradle and when the foot pedal (29) is depressed, the finger ( 28) moves from the path of travel of the first group of lugs (25) and into the path of travel of the lugs (24) of the second group.
