A feeder for feeding animals selected from domestic pets, cage birds, chickens, fish and wild birds. A hopper holds feed, an electric motor and a battery holder A chamber receives feed from the hopper, and has a discharge outlet for discharge of feed. An augur is mounted for rotation and receives drive from the electrical motor. As the augur rotates, it moves feed along the chamber towards the discharge outlet. An indexing mechanism indexes individual turns of the augur. The feeder supplies feed to the discharge outlet in metered amounts. The feeder is formed as two units, namely a base unit with a hopper unit mounted on the base unit. The base unit mounts the electric motor and battery holder. The hopper unit includes the hopper itself, the chamber and the augur. The hopper unit is freely separable from the base unit for cleaning or for filling the hopper.

1. A feeder apparatus for supplying dry feed to animals, the feeder apparatus comprising: a base unit having a battery powered electric motor and a battery holder, said battery holder suitable for receiving at least one battery so as to drive said electric motor solely by power from the at least one battery;a hopper unit mounted onto said base unit, said hopper unit comprising: a hopper adapted to hold the supply of dry feed therein;a chamber positioned adjacent a lower portion of said hopper, said chamber suitable for receiving the dry feed by gravity from said lower portion of said hopper, said chamber having a discharge outlet at one axial end thereof so as to allow for a discharge of the dry feed from said chamber; andan auger rotatably mounted about an axis in said chamber, said electric motor drivingly connected to said auger, said auger adapted to drive the feed along said chamber to said discharge outlet, said hopper unit being entirely freely separable as an entire unit from said base unit for cleaning said hopper or for filling said hopper with the dry feed, said hopper unit being replaceable as an entire unit onto said base unit after being separated therefrom; andan indexer cooperative with said auger so as to index in individual turns so as to supply feed in metered amounts to said discharge outlet of said chamber even as the battery power to the electric motor decreases,wherein each of the base unit and the hopper unit is individually constructed and arranged to be manually portable when separated. 2. The feeder apparatus of claim 1, said auger comprising a helical wire. 3. The feeder apparatus of claim 1, said base unit having a drive mechanism coupled to said electric motor, said drive mechanism engageable with said auger so as to rotate said auger. 4. The feeder apparatus of claim 3, said indexer having a reed switch adapted to be operated in each rotation of said auger, said reed switch being coupled to a control circuit for controlling operation of said electric motor, said indexer further comprising a magnet mounted on said drive mechanism for rotation as said auger rotates so as to bring said magnet into confronting relation with said reed switch once in each rotation of said auger so as to provide a digital input for said control circuit. 5. The feeder apparatus of claim 1, said indexer having a switch adapted to be operated a set number of times in each rotation of said auger, said switch coupled to a control circuit so as to control an operation of said electric motor. 6. The feeder apparatus of claim 5, said control circuit constructed and arranged to detect a blockage of said auger by the dry feed and suitable for causing a temporary reversal of said electric motor in order to unblock the blockage. 7. The feeder apparatus of claim 6, said control circuit adapted to provide a visual or audible warning if the blockage is not removed. 8. The feeder apparatus of claim 5, wherein said control circuit includes a timer and is programmable to operate said electric motor for a preselected number of turns of said auger at times set by the user.
