A feeder and dispenser, as in claim 1, in which said time-controlled means includes a notched disc for selectively releasing each trap-door when the disc is rotated to align the notch with each trap-door to be permitted to open, with each trap-door being supported so upon release it will be free to move to its full open poSition without interference by other doors.
Claim 6
Dependent Claim
62 words
An animal feeder and dispenser, as in claim 1, in which said means on top of the post for supporting said food container consists of a plate with a plurality of radial arms and an anchoring element to secure the plate to the top of said post; and means for releasably securing said circular container to said arms of said supporting means.
Claim 7
Dependent Claim
110 words
An animal feeder and dispenser as in claim 4, in which said time-controlled means is disposed and supported centrally and co-axially on said circular container, and includes a shaft disposed and supported co-axially from said time-controlled means and said notched disc is secured to and supported on said shaft to be rotated by said shaft in a plane immediately beneath said trapdoors to hold all said trapdoors closed until said predetermined time when said disc releases a trapdoor, with the trapdoors hinged from their outer peripheries, to permit free movement of each door upon opening, without interference from a previously opened door, and without interference to a subsequently opened door.
