Fastener applicators

Abstract

A tool for driving staples or nails and simultaneously providing reinforcement therefore. The tool is particularly useful in installing roofing material, although it has equal utility in attaching labels, tags and the like to shipping cases, and siding to buildings, and other purposes. In a preferred embodiment, the tool is provided with a handle which is long enough that a workman may operate the tool without bending over any material amount. The staple or nail driving mechanism may be of the hand-driven type or may be air, electric or spring operated. Connected to the housing of the driving mechanism is a magazine containing a considerable number of fastener reinforcing elements, such as thin metal discs, through which the staple or nail is driven in the same stroke used to drive such fastener into the object to be fastened. In one embodiment of the invention, a coil of thin sheet metal is rotatably disposed within a housing carried by the driving mechanism housing, the leading edge of the strip being fed into position and sheared into tab form, the staple or nail then being driven through the tab.
