Abstract

Abstract A fish self-feeder is mounted over a body of water containing fish and has a particulate feed containing hopper consisting of a tapered receptacle containing a funnel having the spout directed through an opening in the bottom of the container. A pendulum rod hangs vertically from the center of the spout by means of a suspension pin hooked into opposed openings in the spout. A feeder plate is adjustably positioned vertically on the rod forming a spaced obstruction for feed particles falling through the spout. The lower end of the pendulum terminates in a submerged bumper head which, when disturbed by the fish, causes a relative motion between the feeder plate and funnel spout, thereby producing a partial discharge of feed into the water.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 156 words
An animal feeding device comprising: a a receptacle for receiving and storing feed therein, means forming a funnel associated with said receptacle and having a generally cylindrical vertical wall defining a downwardly open spout; b. a suspension pin having opposite ends thereof engaging said spout wall and supporting said pin projecting across said spout; c. a pendulum rod having an upper portion, an intermediate portion and a lower portion, said suspension pin en-gaging said rod at said upper portion and suspending said rod downwardly of said spout; d. a feeder plate having an upper surface and vertically adjustable along said rod intermediate portion, said feeder plate upper surface being generally flat and having a diameter larger than the diameter of said spout constituting a feed support means in its rest position, and e. means for supporting said receptacle at an elevation whereby said rod lower portion is convenient for striking by an animal to be fed.
Claim 2
Dependent Claim 156 words
An animal feeding device comprising: a a receptacle for receiving and storing feed therein, means forming a funnel associated with said receptacle and having a generally cylindrical vertical wall defining a downwardly open spout; b. a suspension pin having opposite ends thereof engaging said spout wall and supporting said pin projecting across said spout; c. a pendulum rod having an upper portion, an intermediate portion and a lower portion, said suspension pin en-gaging said rod at said upper portion and suspending said rod downwardly of said spout; d. a feeder plate having an upper surface and vertically adjustable along said rod intermediate portion, said feeder plate upper surface being generally flat and having a diameter larger than the diameter of said spout constituting a feed support means in its rest position, and e. means for supporting said receptacle at an elevation whereby said rod lower portion is convenient for striking by an animal to be fed.
Claim 3
Dependent Claim 48 words
The device as set forth in claim 1 wherein: a. said receptacle comprises an upright generally cylindrical container having an inside surface tapering inwardly in a downwardly direction, and b. said means forming a funnel is a funnel member having a peripheral edge engaging said tapered inside surface.
Claim 4
Dependent Claim 41 words
The device as set forth in claim 1 wherein: a. said receptacle comprises an upright generally cylindrical container having a bottom wall, and b. said means forming a funnel is a funnel member with said spout projecting through said bottom wall.
Claim 5
Dependent Claim 29 words
The device as set forth in claim 1 wherein: a. said spout wall has opposed openings therein, and b. said pin opposite ends project through said spout wall openings.
Claim 6
Dependent Claim 20 words
The device as set forth in claim 1 wherein: a. said rod lower portion is bent into a non-linear shape.
Claim 7
Dependent Claim 16 words
