Claim 1
Independent Claim
137 words
In the combination of an upright drum, and a lifting ring surrounding, and secured to, the sidewall of the drum; the improvement characterized by the drum sidewall having a horizontal circumferential groove formed therein in spaced relation below the upper end of said drum, and the lifting ring being tightly seated in the groove; said lifting ring including an integral, annular, vertically facing flange projecting radially outwardly from the groove to an outer edge termination a distance beyond the drum sidewall, and an annular lip formed integrally with and upstanding from the outer edge of said annular flange and spaced substantially said distance from the drum sidewall whereby the upstanding lip is exposed exteriorly of the drum for ready, unobstructed access from above and gripping engagement by a gripping device of a drum lifting and transporting vehicle.
Claim 2
Dependent Claim
137 words
In the combination of an upright drum, and a lifting ring surrounding, and secured to, the sidewall of the drum; the improvement characterized by the drum sidewall having a horizontal circumferential groove formed therein in spaced relation below the upper end of said drum, and the lifting ring being tightly seated in the groove; said lifting ring including an integral, annular, vertically facing flange projecting radially outwardly from the groove to an outer edge termination a distance beyond the drum sidewall, and an annular lip formed integrally with and upstanding from the outer edge of said annular flange and spaced substantially said distance from the drum sidewall whereby the upstanding lip is exposed exteriorly of the drum for ready, unobstructed access from above and gripping engagement by a gripping device of a drum lifting and transporting vehicle.
Claim 3
Dependent Claim
44 words
An improvement, as in claim 1, in which the groove is substantially rectangular in cross section providing in the groove a flat bottom and a flat upper face, and the band and the flange being flat and matchingly engaging said bottom and face, respectively.
Claim 4
Dependent Claim
149 words
In the combination of an upright drum, and a lifting ring surrounding, and secured to, the sidewall of the drum; the improvement characterized by the drum sidewall having a horizontal, circumferential groove formed therein in spaced relation below the upper end of said drum, and the lifting ring including an annular, horizontally facing band tightly flush-seated in the groove against the bottom thereof, an annular vertically facing flange formed integrally with the upper edge of the band and projecting radially outwardly therefrom to an outer edge termination a distance beyond the drum sidewall, and an annular lip formed integrally with and upstanding from the outer edge of said annular flange and spaced substantially said distance from the drum sidewall whereby the upstanding lip is exposed exteriorly of the drum for ready, unobstructed access from above and gripping engagement by a gripping device of a drum lifting and transporting vehicle.
Claim 5
