Abstract
Abstract A magazine assembly for a corrugated fastener-driving device is described in which the magazine includes an elongated member having a U-shaped cross section. Longitudinal grooves opening inwardly of the U-shaped member are placed in the outermost ends of the legs of the U-shaped member forming opposed pairs of longitudinal grooves progressively more distant from the base of said U-shaped member. An elongated cover means of substantially inverted U-shaped cross section is provided to cover the U-shaped magazine. The cover means has out-turned flanges adapted to be received by the above-mentioned grooves so that the magazine may be opened and closed by sliding the cover within the grooves. The distance of the cover from the base of the U-shaped magazine may be adjusted by placing the cover in different pairs of grooves. A pusher assembly for yieldably urging the fasteners toward the driving means is mounted on the cover and entirely contained thereon. The pusher which engages with the fasteners rides in a longitudinal slot in the bight of the U-shaped cover. The longitudinal slot opens at the rear end of the cover and extends forwardly toward the driving element. A tension spring having one end anchored to the pusher extends forwardly around a pulley at the forward end of the cover and then rearwardly to be anchored at the rear end of the cover. Proper spacing of the pusher from the cover in order that the pusher will engage with the fasteners in the magazine is obtained by spaced studlike members extending from the pusher to engage with the longitudinal slot in the cover. A detent means, which is either vertically acting or side acting, mounted in the U-shaped magazine member cooperates with the cover to secure the cover in the fully-closed position. The detent means may be released to a first position permitting the cover to slide rearward away from the driving element to a fastener loading position. At this point, the detent means, in said first release position, cooperates with the cover to limit the rearward movement of the cover from the fastener loading position. The detent means may be released further, allowing the cover to slide rearward from the fastener loading position, permitting the cover to be removed from the U-shaped magazine member so that it may be placed in a different pair of grooves in the U-shaped magazine member thereby adjusting the magazine assembly for a different fastener height. The preferred embodiment of the magazine assembly constructed according the principles of this invention is adapted for use in fastenerdriving devices for corrugated fasteners of the type which positions the leading fastener to be engaged by the driving element and subsequently cammed into alignment with the driver element and driven into the workpiece. Thus, a wear plate and blade guide are provided and adapt the drive track to cooperate with the magazine assembly to perform this function.
