Abstract
Abstract The drawings show a marine toilet assembly comprising a first tubular member having an open upper end connected to and supporting a conventional toilet bowl and seat assembly. The lower end of the tubular member has an outlet opening facing generally horizontally and a motor is releasably connected to the tubular member on the side opposite the outlet with its drive shaft extending generally horizontally and aligned with the outlet opening. Positioned in the lower end of the tubular member and releasably connected to the drive shaft is a rotary macerator and waste pump assembly with the waste pump located outwardly of the outlet. A housing member encloses the waste pump and is sealingly and releasably connected to the outlet opening on the tubular member. The housing member has a discharge opening adapted to receive the output from the waste pump. A flush water pump is connected to the motor at the side opposite the outlet and means are provided for supplying treatment chemicals to the water supplied to the flush water pump.

Total Claims: 14
Claim 1
Independent Claim
156 words
A toilet assembly comprising: a first tubular member having an open upper end adapted to be connected to and support a toilet bowl, and a lower end with an outlet opening facing generally horizontally; a motor releasably connected to and supported by said tubular member on the side opposite said outlet in line therewith with its drive shaft extending generally horizontally and aligned with the outlet opening; rotary macerator means positioned in the lower end of said first tubular member being and extending in the direction of said outlet releasably connected to said drive shaft; a waste pump means drivingly connected to said drive shaft and mounted at a location outwardly of said outlet; and, a housing member enclosing the waste pump and sealingly and releasably connected to and supported from the outlet opening on said first tubular member, said housing member having a discharge opening adapted to receive the output from the said waste pump.
Claim 2
Dependent Claim
156 words
A toilet assembly comprising: a first tubular member having an open upper end adapted to be connected to and support a toilet bowl, and a lower end with an outlet opening facing generally horizontally; a motor releasably connected to and supported by said tubular member on the side opposite said outlet in line therewith with its drive shaft extending generally horizontally and aligned with the outlet opening; rotary macerator means positioned in the lower end of said first tubular member being and extending in the direction of said outlet releasably connected to said drive shaft; a waste pump means drivingly connected to said drive shaft and mounted at a location outwardly of said outlet; and, a housing member enclosing the waste pump and sealingly and releasably connected to and supported from the outlet opening on said first tubular member, said housing member having a discharge opening adapted to receive the output from the said waste pump.
Claim 3
Dependent Claim
43 words
The toilet assembly as defined in claim 1 including a water pump connected to said motor at the side opposite said outlet and means for conducting water from said pump to a toilet bowl mounted on the upper end of said tubular member.
Claim 4
Dependent Claim
20 words
The toilet assembly as defined in claim 1 wherein said open upper end is laterally offset from said macerator means.
Claim 5
Dependent Claim
30 words
The toilet assembly as defined in claim 1 wherein macerator means comprises an auger-type blade extending through the lower end of said first tubular member and into said housing member.
Claim 6
Dependent Claim
25 words
