ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an automated animal feeding cabinet apparatus having downwardly rotating food containing shelves which pivot down from one side.
2. Description of the Related Art
The relevant art of interest describes various feeding apparatus, but none discloses the present invention. There is a need for an economical automated cabinet for scheduling the feeding of domestic or wild animals with food from ascending shelves at regular intervals without the requirement for hoppers.
The relevant art will be discussed in the order of perceived relevance to the present invention.
U.K. Patent Application No. 1 444 581 published on Aug. 4, 1976, for Peter Kenyon describes a closed animal food dispenser and open bottom trough feeder having a number of internal vertically spaced and trough shaped food containers for dispensing food bran in water from separate compartments, which troughs are pivotally mounted between a retaining position and a dispensing position. The food containers have releasable catches which are released to allow the containers to drop the food down into an integrated collecting trough. The release mechanisms comprise a vertical rod having release pins rotated at 15° intervals by a 24-hour high torque clock motor. The release pins release a spindle at each trough location by its arm and a catch member extending out to engage an upper end of the feeding trough. When tripped, the trough rotates downward from its bottom pin at its end on a hook support and empties its load of water and food. The food dispenser apparatus is distinguishable for its rotating arm with pins for engagement with pins on each releasable trough which are hinged to the rear panel of the cabinet.
U.S. Pat. No. 3,683,859 issued on Aug. 15, 1972, to Lloyd L. Kirk describes an automatic tripping device for releasing supporting floor members of six or seven cabinet compartments in one or two rows holding hay bales to discharge the hay in a timed sequence. A tripping cord passes through each tripping mechanism of each compartment from a cutoff switch to an electrical actuating device and a weight mounted on an external wall. A solenoid exerts the pulling force for tripping and taking up the cord slack. A floor member is released by a hinged supporting rod at one end and attached by a pivot pin to an arm holding the cord under the spring tension of a clasping member. The automatic tripping device is distinguishable for being based on a solenoid and weighted release cord system.
U.S. Pat. No. 4,350,120 issued on Sep. 21, 1982, to L. Gordon Bittle describes an elongated vertical feeder apparatus having a plurality of storage bins in a vertical stack defined by a movable shelf or open ended boxes for each bin selectively operated to drop stored food packages from the top portion of the feeder by means of a solenoid-operated ejector carriage moving downward. The ejector carriage comprises a horizontal platform supported by two side bare having two wheels each which engage two vertical rails. Two more spring-loaded wheels on the platform contact the vertical rails. The platform supports a solenoid which when actuated pushes out a movable slide on a spring to push out a movable shelf and at the same time release the hold on a retainer tongue on the rear wall. The platform then moves down to the next retainer tongue. The dropped food package enters a chute which has cutting blades to open up the package. The apparatus is distinguishable for the required dropping of food packages from the top portion, cutting the bags open, and its carriage requiring numerous guide wheels and a pair of rails.
U.S. Pat. No. 5,520,143 issued on May 28, 1996, to Robert R. Duin describes an apparatus for automatically dispensing measured amounts of hay flakes, grain, coarse granules, cubes or pellets to livestock on a pre-selected schedule. The apparatus has a rectangular frame with a loading portal on one side and dispensing doors on the opposite side. The row of cells can be arranged horizontally at an inclined angle with doors opening sequentially at the bottom of the cells or vertically with either top or rear-loading configurations. A horizontal linear sequencing bar having spaced slots permit the opening of a cell door when an extending door rod falls into the slot to open the door. A drive motor actuated by a timer control panel drives a pinion which advances a rack portion of the sequencing bar to open each door sequentially. The feeding apparatus is distinguishable for its horizontal opening of bin doors.
U.S. Pat. No. 4,665,863 issued on May 19, 1987, to George F. Toledo describes an animal feeding apparatus comprising a box housing with a plurality of chambers having inclined bottom walls and individual door panels opening downward when released by a rotating beaded chain having one large bead to trip the latches in sequence. A sprocket is driven by a geared down motor to open the feeding doors over a 24 hour or 48 hour duration. The apparatus is distinguishable for its required beaded drive chain and yoked latches.
U.S. Pat. No. 998,423 issued on Jul. 18, 1911, to Franklin M. Stephens describes an automatic stock-feeder apparatus comprising one or a plurality of feed hoppers suspended by swinging trip levers on a cable tensioned by a retractile spring to be unwound from an alarm clock's alarm arbor. The retractile spring can be replaced with a weight on a pulley. The hoppers are attached to a wall above a feed trough and the trip levers unlatch the trap door holding the feed. The apparatus is distinguishable for its requirement for individual feed hoppers and trap door being opened by an alarm clock mechanism.
U.S. Pat. No. 493,219 issued on Mar. 7, 1893, to Daniel McQueen describes a time stock feeder apparatus comprising a plurality of feeding hoppers attached to a rope and trigger on an alarm winding key of an alarm clock. The hoppers have a hinged valve attached by a vertical link to a bell crank which is pivotally secured and attached to the horizontal rope. The apparatus is distinguishable for its alarm clock and rope mechanism.
U.S. Pat. No. 317,708 issued on May 12, 1885, to Titus L. Bissell describes an automatic time stock feeder apparatus comprising a hopper having a trap-door opened by a trigger mechanism with forked arms by an eccentric on a rotating winding arbor of an alarm clock housed in a case positioned on the outside. The apparatus is distinguishable for its hopper structure and clock actuation.
U.S. Pat. No. 4,183,327 issued on Jan. 15, 1980, to Edward C. Olsen describes an automatic horse-feeding apparatus comprising a central hopper having a motor-driven shaft which agitates the feed while driving an impeller distribution assembly which apportions the feed into one or more chutes. A manually controlled damper assembly allows for simultaneously feeding a plurality of horses at different rates from the same feed hopper. An adjustable-control circuit provides for presetting the interval between feedings and the amount of each feeding. The apparatus is distinguishable for its individualized feeding of a plurality of horses from one feeder apparatus.
U.S. Pat. No. 4,492,183 issued on Jan. 8, 1985, to Pierre Chiotasso et al. describes an automatic distributor-feeder with plural compartments arranged in a carousel structure for feeding granular food down the hopper for domestic animals. The apparatus is distinguishable for its carousel structure.
U.S. Pat. No. 5,433,171 issued on Jul. 18, 1995, to Anthony S. Ewell describes an automatic pet food dispenser comprising separate compartments and collection bowls for feeding food from a hopper and water from a tank. Separate pressure sensing mechanisms measure the weight of each bowl for control of the feeding volumes. The apparatus is distinguishable for its computerized feeding mechanism of separated foods.
U.S. Pat. No. 5,230,300 issued on Jul. 27, 1993, to Victor Mezhinsky describes an automatic dry food feeder for animals comprising a box housing including inside a hopper feed
