Patent ID: 7647889

Claim:
An apparatus for receiving and disposing of animal waste comprising: a) a first unit assembly further comprising: (i) an unenclosed compartment open from above used to contain litter for the deposit of animal waste material that allows for ingress and egress of an animal from at least one direction; (ii) a temporary litter storage compartment laterally adjacent to and in communication with the unenclosed compartment; (iii) a screen located between the unenclosed compartment and the temporary compartment; b) a second unit assembly further comprising: (i) a base; (ii) means within the base for movably and rotatably supporting the first unit assembly above the base; (iii) means within the base, located below the means for supporting the first unit assembly, for receiving a waste receptacle such that the waste receptacle remains below the first unit assembly during a physical cycle; (iv) means within the base for allowing communication of waste material from the first unit assembly to a waste receptacle; c) a waste receptacle; and d) means for altering the orientation of the first unit assembly relative to the second unit assembly and the vector force of gravity; whereby alteration of the orientation of the first unit assembly passes litter from the unenclosed compartment to the temporary compartment through the screen, waste material being restrained by the screen and discharged under the force of gravity to the waste receptacle, and wherein reversal of the orientation of the first unit assembly passes litter from the temporary compartment to the unenclosed compartment.
