Definition of "gas-ring" [gas-ring]

• In some forms of breech-loading firearms, a gas-check consisting of a thin steel or copper plate perforated to the exact size of the caliber of the gun, and serving as a face-plate to the breech-block. The chamber of the breech-block is larger than the hole in the plate, so that when a charge explodes in the gun the gas from the explosion flies back into the chamber, forcing the plate or ring forward against the breech of the gun. (noun)
• A work-bench gasolene heating-burner in which the jets of flame are arranged in a circle; a ring burner. (noun)
