Abstract
Abstract A self-cleaning bird cage includes a chamber formed of a plurality of transparent vertical walls and a top enclosing a perch, with a perforated floor for permitting waste from birds to drop through. A cabinet supporting the chamber includes a platform under the floor with rollers at each end and including a roll of thin plastic material which tends to adhere to itself and to other materials which is fed as a web over the rollers to a take-up roll. Waste and debris falling through the perforated floor land on the web. The take-up roll is preferably driven by an electric motor which is operated for a period sufficient to transfer the soiled plastic material onto the take-up roll. A box positioned below the take-up roll collects solid debris such as seed husks which do not adhere to the plastic material. A second, simplified embodiment incorporates a knob to permit an operator to manually wind the plastic material on said take-up roll.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
A self-cleaning bird cage including an enclosed chamber including a plurality of walls of transparent, non-porous material, a perch in said chamber, and a coarse screen constituting a floor at the bottom of said chamber; a base unit supporting said chamber including a cabinet, a roll of sheet plastic material in said cabinet and a take-up roll in said cabinet with said sheet plastic material being of a thickness of no more than about 1 mil and extending in a web across said chamber and below said floor from said roll to said take-up roll; electric motor means connected to said take-up roll and switch means operative to energize said motor to roll said web onto said take-up roll; and a box located in said cabinet under said take-up roll for receiving solid debris falling from said web before it is wound on said take-up roll.
Claim 2
Dependent Claim
146 words
A self-cleaning bird cage including an enclosed chamber including a plurality of walls of transparent, non-porous material, a perch in said chamber, and a coarse screen constituting a floor at the bottom of said chamber; a base unit supporting said chamber including a cabinet, a roll of sheet plastic material in said cabinet and a take-up roll in said cabinet with said sheet plastic material being of a thickness of no more than about 1 mil and extending in a web across said chamber and below said floor from said roll to said take-up roll; electric motor means connected to said take-up roll and switch means operative to energize said motor to roll said web onto said take-up roll; and a box located in said cabinet under said take-up roll for receiving solid debris falling from said web before it is wound on said take-up roll.
Claim 3
Dependent Claim
60 words
A bird cage as claimed in claim 1 wherein timing means is connected to said electric motor means to cause said electric motor means to be operated at desired intervals and for a desired period of time to cause the sheet plastic material above said platform to be transferred to said take-up roll and replaced with clean sheet plastic material.
Claim 4
Dependent Claim
24 words
A bird cage as claimed in claim 2 wherein said timing means includes a clock with means initiating said electric motor means at intervals.
Claim 5
Dependent Claim
155 words
A bird cage comprising a generally rectangular chamber having at least one non-porous wall of transparent material, and a perch in said chamber; a housing supporting said chamber, a generally rectangular platform supported in said housing, and rollers carried on said platform at opposite sides thereof; a roll of sheet plastic material in said housing of no more than about 1 mil thickness, said material being of a type which adheres to itself and to other materials, said material extending in a web across said platform for receiving debris from said chamber; a take-up roll on the opposite side of said housing from said first named roll for receiving said sheet plastic material; and means connected to said take-up roll to roll said web onto said take-up roll; and a box located in said hosing under said take-up roll for receiving solid debris falling from said web before it is wound on said take-up roll.
Claim 6
Dependent Claim
155 words
A bird cage comprising a generally rectangular chamber having at least one non-porous wall of transparent material, and a perch in said chamber; a housing supporting said chamber, a generally rectangular platform supported in said housing, and rollers carried on said platform at opposite sides thereof; a roll of sheet plastic material in said housing of no more than about 1 mil thickness, said material being of a type which adheres to itself and to other materials, said material extending in a web across said platform for receiving debris from said chamber; a take-up roll on the opposite side of said housing from said first named roll for receiving said sheet plastic material; and means connected to said take-up roll to roll said web onto said take-up roll; and a box located in said hosing under said take-up roll for receiving solid debris falling from said web before it is wound on said take-up roll.
Claim 7
Dependent Claim
29 words
A bird cage as claimed in claim 4 wherein the surface of said platform adjacent said web is formed of a material to which said web will not adhere.
Claim 8
Dependent Claim
44 words
A bird cage as claimed in claim 3 wherein said means connected to said take-up roll for rolling said web onto said take-up roll comprises electric motor means and switch means operative to energize said motor to roll said web onto said take-up roll.
Claim 9
Dependent Claim
55 words
A bird cage as claimed in claim 6 wherein timing means is connected to said electric motor means to cause said electric motor means to be operated for a desired period of time to cause the soiled plastic material above said platform to be transferred to said take-up roll and replaced with clean plastic material.
Claim 10
Dependent Claim
202 words
A bird cage comprising a chamber for holding a bird, a perch in said chamber, a perforated floor at the bottom of said chamber, a housing supporting said chamber, a roll of sheet material and a take-up roll in said housing, said sheet material extending in a web below said floor between said roll and said take-up roll, means connected to said take-up roll to roll said web onto said take-up roll, means in said housing for gaining access to said roll and said take-up roll, and receptacle means positioned below said take-up roll; characterized in that: said chamber is formed of a plurality of walls of non-porous transparent material and a top carried above said walls; said sheet material is of a plastic material no more than about 1 mil thick of a type which tends to adhere to itself and to other materials; a rectangular platform is supported in said housing below said web such that said web is supported at least partially on said platform; and rollers are attached to opposite sides of said platform adjacent said roll and said take-up roll to minimize the forces on said web when said web is being wound on said take-up roll.
