Abstract
Abstract A self-cleaning bird bath having a vertical support stand and a shallow double walled bowl pivoted to the upper end thereof so as to be movable from a horizontal position to a substantially vertical position. A piston and cylinder assembly in said vertical support stand with the piston engaging the shallow bowl for tilting the same, a flexible conduit connecting the interior of the hollow bowl with the interior of the cylinder and a second tubular member for supplying water to the cylinder so as to move the piston and fill the shallow bowl by way of apertures in one of the double walls thereof whereby the amount of water delivered to the cylinder will tilt the shallow bowl and/or fill the same.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
In a bird bath a combination of a vertical stand and a shallow bowl pivoted to the upper end thereof so as to be tiltable relative thereto, a piston and cylinder assembly pivotally connected between said vertical stand and said shallow bowl and flexible tubular means establishing communication between the hollow bowl and the cylinder of said piston and cylinder assembly and on the opposite side of the piston thereof with respect to the shallow bowl and secondary tubular means communicating with the cylinder on said opposite side of said piston for supplying water thereto.
Claim 2
Dependent Claim
95 words
In a bird bath a combination of a vertical stand and a shallow bowl pivoted to the upper end thereof so as to be tiltable relative thereto, a piston and cylinder assembly pivotally connected between said vertical stand and said shallow bowl and flexible tubular means establishing communication between the hollow bowl and the cylinder of said piston and cylinder assembly and on the opposite side of the piston thereof with respect to the shallow bowl and secondary tubular means communicating with the cylinder on said opposite side of said piston for supplying water thereto.
Claim 3
Dependent Claim
40 words
The bird bath set forth in claim 1 wherein the shallow bowl comprises a double walled structure with a series of apertures in the inner wall and wherein the flexible tubular means communicates with the area between the double walls.
Claim 4
Dependent Claim
33 words
The bird bath set forth in claim 1 and wherein the shallow bowl is of a configuration permitting all of the water to flow outwardly thereof where it is in substantially vertical position.
Claim 5
Dependent Claim
56 words
The bird bath set forth in claim 1 and wherein the means establishing communication between the cylinder of the piston and cylinder assembly and the shallow bowl includes a restriction reducing the amount of water that can flow therethrough as compared with the amount of water that can flow into the cylinder through the secondary means.
Claim 6
Dependent Claim
79 words
The bird bath set forth in claim 1 and wherein pivot members pivoting said shallow bowl to the upper end of said vertical stand are located adjacent the side wall of the vertical stand and offcenter with respect to the shallow bowl and wherein secondary pivot members on the substantial center of the shallow bowl engage a piston rod of said piston and cylinder assembly, said pivot members being spaced with respect to one another on said shallow bowl.
Claim 7
Dependent Claim
66 words
In a bird bath a combination of a vertical stand and a shallow bowl pivoted to the upper end thereof so as to be tiltable relative thereto, an expansible device connected between said vertical stand and said shallow bowl and flexible tubular means establishing communication between the hollow bowl and the expansible device and secondary tubular means communicating with the expansible device for supplying water thereto.
Claim 8
Dependent Claim
66 words
In a bird bath a combination of a vertical stand and a shallow bowl pivoted to the upper end thereof so as to be tiltable relative thereto, an expansible device connected between said vertical stand and said shallow bowl and flexible tubular means establishing communication between the hollow bowl and the expansible device and secondary tubular means communicating with the expansible device for supplying water thereto.
