ABSTRACT:
A cartridge strip magazine for successively feeding cartridges into the breech of a powder-actuated fastener setting tool. When a cartridge in alignment with the breech is fired, the resultant expanding gas acts to propel a drive piston to launch a fastener. The inlet to the breech is provided with a frusto-conical upper entry section and an inwardly offset frusto-conical lower section having the same slope as the upper section. The magazine is molded of a strip of resilient plastic material having a row of noses projecting therefrom, each nose socketing a cartridge and being adapted to nest within the inlet of the tool breech. Each nose is formed with an outer wall having a frusto-conical lower section which when the nose is nested within the breech abuts and conforms to the lower section of the breech, and an outwardly-offset frusto-conical upper section that then abuts and conforms to the upper section of the breech.
