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