Abstract
Fastener-advancement systems comprise a multiple lever and linkage mechanically operated system operatively connected to the driver blade member of the fastener driving tool, as well as electro-mechanically operated systems, for advancing a leading fastener of a collated strip of fasteners into the driver blade channel of the fastener-driving tool. In the electro-mechanically operated systems, push-type, pull-type, and rotary solenoid actuating members are utilized for moving the fastener-advancement feed pawl or claw member.
Claims20
A fastener advancement system for use within a fastener-driving tool, comprising:
- driving means, reciprocally mounted within a driving channel of a fastener-driving tool for movement between a rearward retracted position and a forward extended position, for driving a leading fastener, of a collated strip of fasteners, through the driving channel, and for discharging the leading fastener of the collated strip of fasteners out from the fastener-driving tool;
- and
- means, operatively connected to said driving means and movable in response to rearward movement of said driving means, for separating the leading fastener of the collated strip of fasteners from the remaining fasteners of the collated strip of fasteners, and for advancing the leading fastener of the collated strip of fasteners into the driving channel of the fastener-driving tool, when said driving means is substantially disposed at said rearward retracted position so as to predispose the leading fastener of the collated strip of fasteners within the driving channel of the fastener-driving tool in preparation for the driving and discharging of the leading fastener of the collated strip of fasteners through the driving channel of the fastener-driving tool and out from the fastener-driving tool by said driving means when said driving means is moved from said rearward retracted position toward said forward extended position.
A fastener-driving tool, comprising:
- a driving channel through which a fastener is to be driven so as to be discharged outwardly from said fastener-driving tool;
- driving means, reciprocally mounted within said driving channel of said fastener-driving tool for movement between a rearward retracted position and a forward extended position, for driving a leading fastener, of a collated strip of fasteners, through said driving channel, and for discharging the leading fastener of the collated strip of fasteners out from said fastener-driving tool;
- and
- means, operatively connected to said driving means and movable in response to rearward movement of said driving means, for separating the leading fastener of the collated strip of fasteners from the remaining fasteners of the collated strip of fasteners, and for advancing the leading fastener of the collated strip of fasteners into said driving channel of said fastener-driving tool, when said driving means is substantially disposed at said rearward retracted position so as to predispose the leading fastener of the collated strip of fasteners within said driving channel of said fastener-driving tool in preparation for the driving and discharging of the leading fastener of the collated strip of fasteners through said driving channel of said fastener-driving tool and out from said fastener-driving tool by said driving means when said driving means is moved from said rearward retracted position toward said forward extended position.
