Abstract:
A fastener-driving tool useful to fasten a dimpled membrane to a foundation wall, via a fastener and a polymeric plug, the fastener-driving tool comprising(a) a nosepiece,(b) means for driving the fastener from the nosepiece, through the polymeric plug and through the dimpled membrane, into the foundation wall,(c) an actuating member mounted movably on said tool and movable thereon between an extended, tool-disabling position and a retracted, tool-enabling position, and(d) a workpiece-contacting probe mounted to the actuating member so as to be conjointly movable with the actuating member,wherein the workpiece-contacting probe includes means including a plug-holding member for holding the polymeric plug as the fastener is being driven through the polymeric plug, the plug holding member having a tubular wall defining a recess that receives the polymeric plug within the recess so that the tubular wall surrounds the polymeric plug, the plug-holding member having at least one pointed element having a point projecting inwardly from and non-movably in relation to the tubular wall, the point constituting means for holding the polymeric plug when the polymeric plug is received in the recess, wherein the workpiece-contacting probe includes a mounting bracket mounted to the actuating member and a tubular body fixed to the mounting bracket, the tubular body including at least one permanent magnet positioned at one side of the tubular-body, the plug-holding member being mounted removably to the tubular body and being held magnetically by the at least one permanent magnet when mounted to the tubular-body, wherein the at least one permanent magnet holds a steel washer, which is made of a magnetizable steel, when the plug-holding member is removed, and wherein the plug-holding member has a tubular portion adapted to fit around the tubular body when the plug-holding member is mounted to the tubular body.
