Abstract
Abstract A magazine and feed assembly for a fastener-driving tool is provided wherein the magazine is formed of a pair of complemental sections which are adapted to assume a plurality of selected positions of assembly and form a chamber in which a plurality of collated fasteners are accommodated. An outlet port is formed by the sections and a guide extends outwardly from said port and terminated at a fastener firing station. Cooperating with the guide is a power-actuated feed means which is adapted to intermittently move the fasteners along the guide to the firing station.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
151 words
In a fastener-driving tool, a fastener magazine and feed assembly comprising a stationary magazine first section; an adjustable magazine second section releasably mounted on said first section and cooperating therewith to form a chamber and an outlet port therefor for accommodating a plurality of collated fasteners; manually actuatable locking means carried by one of said sections and biased to assume a first position to effect engagement with the other of said sections and retain said sections in selected positions of assembled relation to accommodate fasteners of varying size; resilient means cooperating with said sections to effect automatic disassembly of said sections when said locking means is actuated to a second position; a fastener guide extending outwardly from said outlet port; and power-actuated fastener-feed means mounted on said guide for engaging at least one of the leading fasteners accommodated by said guide and moving same a predetermined distance relative to said guide.
Claim 2
Dependent Claim
151 words
In a fastener-driving tool, a fastener magazine and feed assembly comprising a stationary magazine first section; an adjustable magazine second section releasably mounted on said first section and cooperating therewith to form a chamber and an outlet port therefor for accommodating a plurality of collated fasteners; manually actuatable locking means carried by one of said sections and biased to assume a first position to effect engagement with the other of said sections and retain said sections in selected positions of assembled relation to accommodate fasteners of varying size; resilient means cooperating with said sections to effect automatic disassembly of said sections when said locking means is actuated to a second position; a fastener guide extending outwardly from said outlet port; and power-actuated fastener-feed means mounted on said guide for engaging at least one of the leading fasteners accommodated by said guide and moving same a predetermined distance relative to said guide.
Claim 3
Dependent Claim
46 words
The fastener magazine and feed assembly of claim 1 wherein said first and second sections are of traylike configuration and disposed in inverted telescoping self-adjusting relation; the extent to which said sections are telescoped being adjusted to the length of the fasteners accommodated within said chamber.
Claim 4
Dependent Claim
47 words
The fastener magazine and feed assembly of claim 2 wherein both of said sections are provided with complementary portions cooperating with one another to form the outlet porT through which only a single collated fastener is passable at a given time from said chamber to said guide.
Claim 5
Dependent Claim
45 words
The fastener magazine and feed assembly of claim 2 wherein said first and second sections are adapted to assume a plurality of selected telescoping positions, and said second section is provided with exposed indicia indicating the selected telescoping position in which said sections are assembled.
Claim 6
Dependent Claim
73 words
