Fastener driving apparatus

Claim 2

A magazine feed for a fastener-driving tool of the type having fastener-driving means operable to drive fasteners from an elongated strip of detachably connected fasteners into a workpiece having an elongated fastener feed track, the combination comprising means for storing and sequentially feeding elongated strips of detachably connected fasteners to said feed track including a feedbin for receiving a plurality of elongated strips of detachably connected fasteners in side-by-side relation and for delivering said strips sequentially from a position to one side of the axis of said feed track into a bin track coaxially with said feed track, means interconnecting said bin track and said feed track for guiding strips of fasteners between said bin track and said guide track, first pusher means movable through an advance stroke to bias a strip in said bin track to move said strip therefrom and to permit another strip to feed from said bin onto said bin track, and movable through a return stroke to engage the last-mentioned strip, and second pusher means engageable with the strip on said guide track only during the return stroke of said first pusher means.

Claim 3

A magazine feed as set forth in claim 1 wherein said first pusher means includes a carriage reciprocally movable along said bin track, and having a pawl engaging a strip of staples during its advancing stroke, and slideable over a strip during the return stroke of said carriage.

Claim 4

A magazine feed as set forth in claim 1 wherein the second-mentioned pusher comprises a member frictionally engageable with a strip of staples biasing said strip forwardly during the return stroke of said carriage.

Claim 5

A magazine feed for a fastener driving tool of the type having fastener-driving means operable to drive fasteners from an elongated strip of detachably connected fasteners into a workpiece having an elongated fastener-feed track, the combination comprising means for storing and sequentially feeding elongated strips of detachably connected fasteners to said feed track including a feedbin for receiving a plurality of elongated strips of detachably connected fasteners in side-by-side relation and for delivering said strips sequentially from a position to one side of the axis of said feed track into a bin track coaxially with said feed track, means interconnecting said bin track and said feed track for guiding strips of fasteners between said bin track and said guide track, first pusher means movable through an advance stroke to bias a strip in said bin track to move said strip therefrom and to permit another strip to feed from said bin onto said bin track, and movable through a return stroke to engage the last-mentioned strip, and second pusher means engageable with the strip on said guide track during the return stroke of said first pusher means, said second mentioned pusher means comprises a member frictionally engaging with a strip of staples biasing said strip forwardly during the return stroke of said carriage, said last mentioned pusher means comprising a power cylinder, and said member being connected to the piston rod of said cylinder engaging said strip at an angle providing a forward component of bias.

Claim 6

A magazine feed for a fastener driving tool of the type having fastener-driving means operable to drive fasteners from an elongated strip of detachably connected fasteners into a workpiece having an elongated fastener-feed track, the combination comprising means for storing and sequentially feeding elongated strips of detachably connected fasteners to said feed track including a feedbin for receiving a plurality of elongated strips of detachably connected fasteners in side-by-side relation and for delivering said strips sequentially from a position to one side of the axis of said feed track into a bin track coaxially with said feed track, means interconnecting said bin track and said feed track for guiding strips of fasteners between said bin track and said guide track, first pusher means movable through an advance stroke to bias a strip in said bin track to move said strip therefrom and to permit another strip to feed from said bin onto said bin track, and movable through a return stroke to engage the last-mentioned strip, and second pusher means engageable with the strip on said guide track during the return stroke of said first pusher means, said second mentioned pusher means comprises a member frictionally engaging with a strip of staples biasing said strip forwardly during the return stroke of said carriage, said last mentioned pusher means comprising a power cylinder, and said member being connected to the piston rod of said cylinder engaging said strip at an angle providing a forward component of bias.

Claim 7

In combination, the magazine feed as set forth in claim 1, and an apparatus for driving fasteners into a workpiece comprising a power driven fastener driving tool, a workpiece support means adapted to support a workpiece adjacent said tool, motor means operable for producing relative movement between said tool and said support to place said tool in contact with a workpiece on said support means, manual control means movable between a normally inoperative position to an operative position for operating said motor means, and trigger means operable between a normal and drive position by the movement of said fastener driving tool relative to said support means.

Claim 8

A magazine feed for a fastener-driving tool of the type having fastener-driving means operable to drive fasteners from an elongated strip of detachably connected fasteners into a workpiece, comprising an elongated fastener-feed track, first pusher means reciprocally movable through an advance stroke to bias strips of staples in said track toward the drive track of said fastener-driving tool and movable through a rapid return stroke to engage an additional strip of staples for advancement toward the drive track, and second pusher means effective only during the return stroke of the first pusher means to bias strips of fasteners on said feed track toward the drive track of said fastener-driving tool.

Claim 9

A magazine feed for a fastener-driving tool of the type having fastener-driving means operable to drive fasteners from an elongated strip of detachably connected fasteners into a workpiece, comprising an elongated fastener-feed track, first pusher means reciprocally movable through an advance stroke to bias strips of staples in said track toward the drive track of said fastener-driving tool and movable through a rapid return stroke to engage an additional strip of staples for advancement toward the drive track, and second pusher means effective only during the return stroke of the first pusher means to bias strips of fasteners on said feed track toward the drive track of said fastener-driving tool.
