Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A vessel comprising a Hollow cylindrical member having one open end; and a closure assembly for said cylindrical member, said closure assembly comprising a plurality of stacked discs coaxially aligned with each other and with said cylindrical member, said discs extending within said open end with the outermost disc extending flush with said open end, the diameters of said discs being successively reduced from said outermost disc to the innermost disc, and the outer diameter of each of said discs being less than the inner diameter of the wall of said cylindrical member to define spaces therebetween, ring means extending in the spaces between said disc and said wall, a plurality of tapped bores being formed along the interface between said ring means and said wall and between said discs and said ring means, and a shear stud extending in each tapped bore to secure said ring means to said wall and said discs to said ring means.
Claim 2
Dependent Claim
158 words
A vessel comprising a Hollow cylindrical member having one open end; and a closure assembly for said cylindrical member, said closure assembly comprising a plurality of stacked discs coaxially aligned with each other and with said cylindrical member, said discs extending within said open end with the outermost disc extending flush with said open end, the diameters of said discs being successively reduced from said outermost disc to the innermost disc, and the outer diameter of each of said discs being less than the inner diameter of the wall of said cylindrical member to define spaces therebetween, ring means extending in the spaces between said disc and said wall, a plurality of tapped bores being formed along the interface between said ring means and said wall and between said discs and said ring means, and a shear stud extending in each tapped bore to secure said ring means to said wall and said discs to said ring means.
Claim 3
Dependent Claim
37 words
The vessel of claim 1 wherein a plurality of successive counterbores of varying diameters are disposed in said wall, said ring means comprising a plurality of individual rings extending between a corresponding disc and a corresponding counterbore.
Claim 4
Dependent Claim
70 words
The vessel of claim 2 wherein there is a series of rings extending between each disc and a corresponding counterbore, the rings of each series being concentric and being nestled one within the other, with a plurality of spaced tapped bores being formed along the interface between the adjacent rings of each series, and further comprising a shear stud extending in each of said bores to secure said rings together.
Claim 5
Dependent Claim
25 words
The assembly of claim 1 further comprising means defining at least one opening through said discs to permit access to the interior of said vessel.
Claim 6
Dependent Claim
130 words
A vessel comprising a hollow cylindrical member having one open end; and a closure assembly for said cylindrical member, said closure assembly comprising a plurality of concentric rings extending within said open end, said rings being of varying diameters and being nestled one within the other, the thicknesses of said rings being successively reduced from the outermost ring to the innermost ring, at least one of said rings being formed by two half portions, a plurality of tapped bores being formed along the interface between said outermost ring and the wall of said cylindrical member and between the adjacent rings, and a shear stud extending in each tapped bore to secure said outermost ring to said wall, said adjacent rings to each other and said half portions to each other.
Claim 7
Dependent Claim
130 words
A vessel comprising a hollow cylindrical member having one open end; and a closure assembly for said cylindrical member, said closure assembly comprising a plurality of concentric rings extending within said open end, said rings being of varying diameters and being nestled one within the other, the thicknesses of said rings being successively reduced from the outermost ring to the innermost ring, at least one of said rings being formed by two half portions, a plurality of tapped bores being formed along the interface between said outermost ring and the wall of said cylindrical member and between the adjacent rings, and a shear stud extending in each tapped bore to secure said outermost ring to said wall, said adjacent rings to each other and said half portions to each other.
Claim 8
Dependent Claim
26 words
The vessel of claim 5 further comprising a disc extending within the opening in the innermost ring and means for securing said disc to said ring.
