Abstract
Abstract There is disclosed herein a radiator wherein grooves formed in a tank flange and in a header match each other and a mound formed on an associated clamping strip. Tapered edges formed on locking tabs cut in the tank flange cooperate with a sloped surface on the clamping strip when bent inwardly to urge the clamping strip and header toward the tank flange so as to compress a sealing gasket between the header and tank flange grooves, eliminating the need for solder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
A radiator comprising a tank having a mounting skirt formed at the lower end thereof, said mounting skirt including a first flange portion extending laterally therefrom and a second flange portion extending vertically downwardly from said first flange portion, a longitudinal groove formed along said first flange portion, and spaced tabs cut in the free edge of the second flange portion, each of said tabs having a tapered upper edge; a header having a groove formed adjacent the peripheral edge thereof such that the protrusion side of the groove substantially exactly matches said longitudinal groove; a clamping strip having a mound formed on the upper surface thereof substantially exactly matching said groove in said header, and a slope formed on the bottom surface thereof; and a sealing gasket confined between said protrusion side of said groove in said first flange and said longitudinal groove, and compressed therebetween by virtue of said tapered tabs being bent inwardly against said sloped bottom surface of said clamping strip.
Claim 2
Dependent Claim
165 words
A radiator comprising a tank having a mounting skirt formed at the lower end thereof, said mounting skirt including a first flange portion extending laterally therefrom and a second flange portion extending vertically downwardly from said first flange portion, a longitudinal groove formed along said first flange portion, and spaced tabs cut in the free edge of the second flange portion, each of said tabs having a tapered upper edge; a header having a groove formed adjacent the peripheral edge thereof such that the protrusion side of the groove substantially exactly matches said longitudinal groove; a clamping strip having a mound formed on the upper surface thereof substantially exactly matching said groove in said header, and a slope formed on the bottom surface thereof; and a sealing gasket confined between said protrusion side of said groove in said first flange and said longitudinal groove, and compressed therebetween by virtue of said tapered tabs being bent inwardly against said sloped bottom surface of said clamping strip.
Claim 3
Dependent Claim
135 words
A radiator comprising a tank having a mounting skirt formed at the lower end thereof, said mounting skirt including a longitudinal groove formed along a first portion thereof, and spaced tabs cut in a second free edge portion thereof, each of said tabs having a tapered upper edge; a header having a bend formed adjacent the peripheral edge thereof substantially exactly matching said longitudinal groove; a clamping strip having a mound formed on the upper surface thereof substantially exactly matching said bend in said header, and a slope formed on the bottom surface thereof; and a sealing gasket confined between said bend in said header and said longitudinal groove in said tank mounting skirt, and compressed therebetween by virtue of said tapered tabs being bent inwardly against said sloped bottom surface of said clamping strip.
Claim 4
Dependent Claim
135 words
A radiator comprising a tank having a mounting skirt formed at the lower end thereof, said mounting skirt including a longitudinal groove formed along a first portion thereof, and spaced tabs cut in a second free edge portion thereof, each of said tabs having a tapered upper edge; a header having a bend formed adjacent the peripheral edge thereof substantially exactly matching said longitudinal groove; a clamping strip having a mound formed on the upper surface thereof substantially exactly matching said bend in said header, and a slope formed on the bottom surface thereof; and a sealing gasket confined between said bend in said header and said longitudinal groove in said tank mounting skirt, and compressed therebetween by virtue of said tapered tabs being bent inwardly against said sloped bottom surface of said clamping strip.
