Abstract
Abstract Drainage catch basin structures embodying dual level adjusting means, and comprising a rectangular top section containing a chamber with an elongated drainage water inlet communicating therewith and to be positioned in alignment with a street curb, said chamber having a rectangular outlet at its lower end; a base section having a generally circular interior and a water outlet; and an intermediate or transition section having a rectangular inlet conforming to the outlet of the top section and a circular outlet conforming with the upper end of the base section. The top section may have a non-skid surface cast therein and a man hole opening closed by a cover, and its marginal edges may be protected by angle iron to prevent chipping in use or in handling. The top section has four leveling bolts cast therein at its lower edge for effecting fine adjustment thereof side to side or front to rear, relative to an underlying section to conform its top surface to a desired side walk or street grade level. The transition section has sleeves cast therein to receive the lower ends of the leveling bolts. A pair of tapered adjusting rings, each of which is of greater height at one point than at a diametrically opposite point, can be interposed between the transition section and the base or other underlying section, and so positioned circumferentially relative to each other that the upper surface of the top section can be adjusted to conform to any major inclinations in road grade.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
253 words
A concrete drainage catch basin comprising: a rectangular top section having a horizontal top wall, an upright rear wall, an upright front wall and upright side walls interconnecting said rear and front walls, said front wall having an elongated drain opening extending therethrough for water drainage and including a wall portion extending across the lower side of said drain opening, said top section containing a chamber communicating with said drain opening and having a generally rectangular outlet opening at the lower edge thereof defined by the inner surface of said upright rear and side walls and said front wall portion; a second section containing a chamber having a generally circular inlet opening at its upper end and having an upper edge defining said circular inlet opening; and an intermediate transition section between said top section and said second section having a rectangular inlet opening at its upper end conforming in shape to the rectangular outlet opening at the lower edge of said top section, said intermediate section having a circular outlet opening at its lower end and having a lower edge defining said circular outlet opening and conforming in shape to said circular inlet opening of said second section, said upper edge of said intermediate transition section confronting the lower edge of said top section, and said lower edge of said transition section confronting the upper edge of said second section, said upper, intermediate and second sections having substantially continuous tongue and groove joints between the contiguous edges thereof interlocking the sections together.
Claim 2
Dependent Claim
253 words
A concrete drainage catch basin comprising: a rectangular top section having a horizontal top wall, an upright rear wall, an upright front wall and upright side walls interconnecting said rear and front walls, said front wall having an elongated drain opening extending therethrough for water drainage and including a wall portion extending across the lower side of said drain opening, said top section containing a chamber communicating with said drain opening and having a generally rectangular outlet opening at the lower edge thereof defined by the inner surface of said upright rear and side walls and said front wall portion; a second section containing a chamber having a generally circular inlet opening at its upper end and having an upper edge defining said circular inlet opening; and an intermediate transition section between said top section and said second section having a rectangular inlet opening at its upper end conforming in shape to the rectangular outlet opening at the lower edge of said top section, said intermediate section having a circular outlet opening at its lower end and having a lower edge defining said circular outlet opening and conforming in shape to said circular inlet opening of said second section, said upper edge of said intermediate transition section confronting the lower edge of said top section, and said lower edge of said transition section confronting the upper edge of said second section, said upper, intermediate and second sections having substantially continuous tongue and groove joints between the contiguous edges thereof interlocking the sections together.
Claim 3
Dependent Claim
44 words
A drainage catch basin as defined in claim 1, wherein the second section is a base section having side walls and a bottom wall forming said circular chamber therein, said second section having at least one water outlet opening communicating with the chamber therein.
Claim 4
Dependent Claim
33 words
A drainage catch basin as defined in claim 2, wherein the exterior of the base section is polygonal, and wherein water outlet openings are formed in at least two of the sides thereof.
Claim 5
Dependent Claim
35 words
A drainage catch basin as defined in claim 1, wherein the second section is a plain circular ring, and including in addition, a base section disposed below said ring having at least one outlet opening.
Claim 6
Dependent Claim
116 words
A drainage catch basin as defined in claim 1, wherein adjusting means is disposed between the top section and the transition section for adjusting the level of the top surface of the top section to conform to a desired grade inclination, said adjusting means comprising bolts having their heads imbedded in the lower edge of the top section and their shanks projecting below said top section, each bolt having an adjusting nut thereon, said transition section having sleeves to receive the shank of said bolts, and wherein the tongue and groove between said top and intermediate sections are both notched in the region of said adjusting nuts and sleeves to provide access to said adjusting nuts.
Claim 7
Dependent Claim
77 words
A drainage catch basin as defined in Claim 1, wherein a pair of tapered adjusting rings is interposed between the transition section and the second section, each of said rings being of different height at diametrically opposite points thereof, said pair of rings having a tongue and groove joint therebetween, the upper ring having a tongue and groove connection with said transition section and the lower ring having a tongue and groove connection with said second section.
Claim 8
Dependent Claim
59 words
A drainage catch basin as defined in Claim 1, wherein the front wall of the top section has an upward extension forming a ridge simulating a curb, and wherein the top surface of said section is depressed inwardly of said ridge to receive paving material to cover the top section to the level of the top of said ridge.
Claim 9
Dependent Claim
39 words
A drainage catch basin as defined in claim 1, wherein each of the side walls has a notch formed in its exterior in the region of the front wall for interlocking the top section with an adjacent concrete curb.
