  • Patent number: 7726534
    Abstract: A magazine includes a feeding tray having a nail path to allow passage of one nail strip and a loading space in spatial communication with the nail path and that is adapted for accommodating a plurality of stacked nail strips, a tray cover coupled to the feeding tray, and a first pusher unit connected detachably to the feeding tray and adapted to press against an uppermost one of the nail strips so as to push a lowermost one of the nail strips into the nail path, and a second pusher unit. When the lowermost one of the nail strips is moved into the nail path, it is pushed toward the nail outlet by the second pusher unit. The tray cover is slidable to uncover at least one of the nail path, thereby permitting an additional nail strip to be placed into the nail path.

  • Patent number: 6837414
    Abstract: A magazine includes a feeding tray adapted to be secured to a powered nail-driving tool and to accommodate stacked layers of nails, a gate member slidably disposed on the feeding tray to urge the lowermost layer of nails toward the tool, a nail-supplying member disposed over the feeding tray and having a stacking opening which is communicated with the feeding tray and which receives the layers of nails, and a separating member interposed between the nail-supplying member and the gate member. The separating member is coupled to the gate member so as to be movable therewith away from the stacking opening in a retracting course of the gate member for loading of the nails into the feeding tray, and to be moved underneath the stacking opening in an advancing course of the gate member.
