Abstract
Abstract An interconnection between a tube and a plate in which said tube is received in an opening in the plate and said tube and plate are movable radially with respect to each other, said tube and plate being radially movable with respect to the tube axis. A pair of washers are disposed on opposite sides of the plate around the tube and over the plate opening with a pair of projections on the tube holding the washers against said plate. One of said washers has a sleeve engageable with the other washer to prevent said washers from binding against the plate thereby permitting relative movement between said plate and tube.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A tube-plate interconnection comprising a plate having an opening formed therein, a first annular washer abutting one face of said plate, said first washer having a sleeve portion projecting through the opening in said plate, a second annular washer abutting the plate face opposite said one face and one end of said sleeve portion, the opening in said plate has a crosssection larger than the outer diameter of said sleeve portion and smaller than the outer diameters of said first and second washers, a tube extending through said second washer and sleeve, and a pair of annular projections fixedly positioned and on said tube abutting said first and second washers for retaining said washers in radial sliding sealing engagement with the opposed faces of said plate.
Claim 2
Dependent Claim
126 words
A tube-plate interconnection comprising a plate having an opening formed therein, a first annular washer abutting one face of said plate, said first washer having a sleeve portion projecting through the opening in said plate, a second annular washer abutting the plate face opposite said one face and one end of said sleeve portion, the opening in said plate has a crosssection larger than the outer diameter of said sleeve portion and smaller than the outer diameters of said first and second washers, a tube extending through said second washer and sleeve, and a pair of annular projections fixedly positioned and on said tube abutting said first and second washers for retaining said washers in radial sliding sealing engagement with the opposed faces of said plate.
Claim 3
Dependent Claim
142 words
A tube-plate interconnection comprising a plate having an opening formed therein, a first annular washer abutting one face of said plate, said first washer having a sleeve portion projecting through the opening in said plate, said sleeve portion having a length at least equal to the thickness of said plate, a second annular washer abutting the plate face opposite said one face and one end of said sleeve portion, the opening in said plate having a cross-section larger than the outer diameter of said sleeve portion and smaller than the outer diameters of said first and second washers, a tube extending through said second washer and sleeve portion, and a pair of annular projections fixedly positioned on said tube and abutting said first and second washers for retaining said washers in radial sliding sealing engagement with the opposed faces of said plate.
Claim 4
Dependent Claim
142 words
A tube-plate interconnection comprising a plate having an opening formed therein, a first annular washer abutting one face of said plate, said first washer having a sleeve portion projecting through the opening in said plate, said sleeve portion having a length at least equal to the thickness of said plate, a second annular washer abutting the plate face opposite said one face and one end of said sleeve portion, the opening in said plate having a cross-section larger than the outer diameter of said sleeve portion and smaller than the outer diameters of said first and second washers, a tube extending through said second washer and sleeve portion, and a pair of annular projections fixedly positioned on said tube and abutting said first and second washers for retaining said washers in radial sliding sealing engagement with the opposed faces of said plate.
Claim 5
Dependent Claim
124 words
A tube-plate interconnection comprising a plate having an opening formed therein, a pair of annular washers slidably carried against the opposed faces of said plate, said washers having inner and outer diameters respectively substantially smaller and greater than the cross-section of the plate opening, means extending between and engaging said washers through the opening in said plate to provide a minimum spacing between the inner portions of said washers, the opening in said plate having a cross-section larger than the outer cross-section of said means, a tube extending through said washers and said means, and a pair of annular projections fixedly positioned on said tube abutting said washers for retaining said washers in radial sliding sealing engagement with the opposed faces of said plate.
Claim 6
