FASTENER-DRIVING AND BATTEN-POSITIONING MACHINE

A fastener-driving and batten-positioning machine useful in roofing applications. A shoe, which has an underside and a pair of spaced guides depending from the underside, is arranged to position a batten over a sheet of roofing material, beneath the underside and between the guides, while the batten is being fastened. A stand-up screw gun, which is incorporated into the machine, is used to drive a fastener, such as a screw, through a batten, through the sheet and through any underlying sheets of roofing materials, into an underlayment. The screw gun is mounted to the shoe, which is mounted to a base for relative movement between the shoe and the base. The shoe is biased gravitationally, and by a spring, so as to urge the shoe toward the batten while the batten is being fastened. A canister, which is mounted to the base, is arranged to receive the batten in a coil, which tends to expand when released, and to supply the batten to the shoe, through an outlet of the canister.
