  • Animal feeder, feeder mount, feeder monitor, and feeder monitoring network
    Patent number: 6748898
    Abstract: An animal feeder has a hopper for storing pieces of food. The bottom of the hopper has an opening accessible by an animal. The opening is smaller than a piece of food, but large enough for the animal to gnaw the food through the opening. The hopper has a surface adjacent the opening, to receive fallen gnawed food and hold the fallen gnawed food in a position accessible by the animal for eating. The hopper engages a mounting bracket. The bracket has a lip which partially covers the receiving surface of the hopper to physically limit the animal from leaning on the hopper and to prevent the hopper from tipping back so far that it falls off the conical mount. A conical mount transmits a downward force from the conical bottom surface to a sensor, but does not transmit an upward force or moment to the sensor.
    Type: Grant

  • Feeder monitor and feeder monitoring network
    Patent number: 6542850
    Abstract: An animal feeder has a hopper for storing pieces of food. The bottom of the hopper has an opening accessible by an animal. The opening is smaller than a piece of food, but large enough for the animal to gnaw the food through the opening. The hopper has a surface adjacent the opening, to receive fallen gnawed food and hold the fallen gnawed food in a position accessible by the animal for eating. The hopper engages a mounting bracket. The bracket is directly attachable to the animal's cage. The bracket has a lip which partially covers the receiving surface of the hopper to physically limit the animal from leaning on the hopper and to prevent the hopper from tipping back so far that it falls off the conical mount. A conical bottom surface is attached to the hopper. The conical bottom surface seats on a conical mount. The conical mount transmits a downward force from the conical bottom surface to a sensor, but does not transmit an upward force or moment to the sensor.
