Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
216 words
A prefabricated waste-disposal unit that may be permanently connected to an underground sewerline in an area in which a vehicle containing a waste-receiving tank will be parked to effect communication by a conduit with said sewerline and a valve assembly on said tank, said valve assembly when in an open position allowing waste to drain through said conduit to said unit and then to said sewerline, said unit comprising: a. a receptaCle that includes a bottom and sidewalls and end walls extending upwardly therefrom, said bottom having first and second openings therein; b. a plurality of first tubular members connected end-to-end that extend through said first opening and are disposed above and below said bottom and substantially normal thereto; c. a drain disposed in said second opening; d. first means for connecting said drain to said tubular members below said bottom; e. second means for holding said receptacle in an embedded fixed position in the ground adjacent said area whereby said conduit can be connected to the uppermost one of said first tubular members; and f. third means for connecting the lowermost one of said tubular members to said sewer to permit waste discharged into said first tubular members through said uppermost one thereof or through said drain and first means to flow to said sewer.
Claim 2
Dependent Claim
216 words
A prefabricated waste-disposal unit that may be permanently connected to an underground sewerline in an area in which a vehicle containing a waste-receiving tank will be parked to effect communication by a conduit with said sewerline and a valve assembly on said tank, said valve assembly when in an open position allowing waste to drain through said conduit to said unit and then to said sewerline, said unit comprising: a. a receptaCle that includes a bottom and sidewalls and end walls extending upwardly therefrom, said bottom having first and second openings therein; b. a plurality of first tubular members connected end-to-end that extend through said first opening and are disposed above and below said bottom and substantially normal thereto; c. a drain disposed in said second opening; d. first means for connecting said drain to said tubular members below said bottom; e. second means for holding said receptacle in an embedded fixed position in the ground adjacent said area whereby said conduit can be connected to the uppermost one of said first tubular members; and f. third means for connecting the lowermost one of said tubular members to said sewer to permit waste discharged into said first tubular members through said uppermost one thereof or through said drain and first means to flow to said sewer.
Claim 3
Dependent Claim
49 words
A waste-disposal unit as defined in claim 1 in which said second means is a body of concrete that is embedded in the ground and extends around the sidewalls and end walls of said receptacle, and the upper surface of said body of concrete defining a rectangularly shaped apron.
Claim 4
Dependent Claim
95 words
A waste-disposal unit as defined in claim 2 in which the inner edge portion of said apron defines a recess that is disposed above the upper extremities of said sidewalls and end walls, with the upper extremity of said uppermost one of said tubular members situated below the lowermost surfaces of said recesses, and said unit in addition including: g. a cover that has the edge portions thereof removably supported in said recesses when said waste-disposal unit is not in use, and said cover when in place serving to conceal the interior of said receptacle.
Claim 5
Dependent Claim
33 words
A waste-disposal unit as defined in claim 2 in which said first means is a curved tubular member that is in communication with said drain and the interior of said first tubular members.
Claim 6
Dependent Claim
28 words
A waste-disposal unit as defined in claim 4 in which said third means is a tubular S-trap that is in communication with said lowermost member and said sewer.
Claim 7
Dependent Claim
28 words
A waste-disposal unit as defined in claim 4 in which said third means is a tubular P-trap that is in communication with said lowermost member and said sewer.
Claim 8
Dependent Claim
31 words
A waste-disposal unit as defined in claim 4 in which said third means is at least one curved tubular member that is in communication with said lowermost member and said sewer.
Claim 9
Dependent Claim
50 words
A waste-disposal unit as defined in claim 1 in which said receptacle and first tubular members are formed from a nonmetallic dimensionally stable material, and said uppermost one of said first tubular members has at least a portion thereof that is angularly disposed relative to said bottom of said receptacle.
Claim 10
Dependent Claim
59 words
A waste-disposal unit as defined in claim 2 in which said receptacle is formed from a metallic material that is resistant to corrosion, and said unit in addition including: g. a continuous horizontal flange that extends outwardly from the upper extremities of said end walls and sidewalls and overlies a portion of said concrete body that defines said apron.
Claim 11
Dependent Claim
37 words
A waste-disposal unit as defined in claim 2 in which said upper surface of said concrete body slopes downwardly and outwardly relative to said receptacle to prevent surface water entering said receptacle and flowing to said sewerline.
