    • A pneumatic fastener driving tool includes a return system for efficiently and rapidly returning a drive piston to the static position and effecting a fastener feeding operation. A housing defines a pressure fluid reservoir connected by a pneumatic control system to a first side of a drive piston to move a driver blade through a drive track in a drive stroke. A pressure fluid actuated fastener feed assembly advances fasteners along a feed path to the drive track. Following a drive stroke, the return system connects the reservoir to the second side of the drive piston for moving the drive piston and driver blade in a return stroke. The return system also connects the reservoir to the fastener feeding assembly for feeding of a fastener. The return system includes two separate return valves operable at different flow capacities and fluid pressures for drive piston return and for fastener feeding.

    • A compression tacker for driving fasteners includes a frame defining a nose portion and a grip portion. A front jaw is pivotally and removably mounted on the nose portion to define a drive track. A plunger is reciprocated in the drive track. The front jaw includes a locking mechanism that upon actuation by the operator of the tool, unlocks the jaw from the frame and allows it to be pivoted relative to the frame to expose the drive track. A handle for actuating the plunger is mounted on the frame and includes a bearing about which a spring is mounted. A workpiece engaging jaw may be removably fastened to the nose portion. The workpiece jaw includes upper and lower surfaces for engaging different workpieces.
    • 用于驱动紧固件的压紧粘合剂包括限定鼻部和抓握部的框架。 前颚枢转地和可拆卸地安装在鼻部上以限定驱动轨道。 柱塞在驱动轨道中往复运动。 前钳口包括锁定机构,该操作机构在操作者致动时,将卡爪从框架解锁,并允许其相对于框架枢转以露出驱动轨道。 用于致动柱塞的把手安装在框架上,并且包括一个轴承,弹簧围绕该轴承安装。 工件接合爪可以可拆卸地紧固到鼻部。 工件夹爪包括用于接合不同工件的上表面和下表面。

    • A tool for driving uncollated nails includes a tool body with a nose portion defining a drive track wherein a driver blade moves in drive and return strokes. A magazine carried by the body supports a row of nails, and a pusher urges the nails along a feed path toward the drive track. The magazine is adjustable for tailoring the feed path width to the nail size. Individual nails are advanced from the magazine to a drive position in the drive track by an escapement mechanism operated in timed relationship with the driver blade, and an advanced nail is held in the drive position by a magnet assembly supported by the tool nose portion. Nails are positively advanced and are properly oriented by the escapement mechanism independently of the number of nails, the pusher force, or other conditions in the magazine. The tool magazine is quickly and conveniently loaded with nails supplied in an oriented condition from a loading chute. The loading operation is automatic in response to engagement of the magazine with the chute, and does not require awkward manipulation of the pusher. Coupling members on the magazine and on the chute are mated by means of ramp and guide structures. In the mated position, stops in the nail path are opened to permit nails to slide from the chute into the magazine.
    • 用于驱动未折叠钉子的工具包括具有限定驱动轨道的鼻部的工具主体,其中驱动器刀片在驱动和返回行程中移动。 由身体携带的杂志支撑一排指甲,并且推动器沿着沿着驱动轨道的馈送路径推动指甲。 这个杂志是可调整的,用于根据钉子尺寸调整进给路径宽度。 单个指甲通过与驱动器刀片定时关系操作的擒纵机构从刀库前进到驱动轨道中的驱动位置,并且先进的钉子由由刀尖部分支撑的磁体组件保持在驱动位置。 钉子是积极进取的,并且由擒纵机构适当地定向,独立于钉子的数量,推动力或杂志中的其他条件。 工具箱快速方便地装载从装载滑槽以定向状态提供的指甲。 响应于料仓与滑槽的接合,加载操作是自动的,并且不需要对推动器的笨拙的操纵。 杂志和滑槽上的耦合元件通过斜坡和引导结构配合。 在配合位置,指甲路上的停止位置打开,以便指甲从滑槽滑入料仓。

    • An electric nailer includes a body and a fastener magazine pivotally connected thereto. The nailer also includes a switch for energizing the nailer that is engagable by a safety to prevent actuation. The safety is moved out of engagement with the switch upon pivoting of the magazine. The magazine includes a pusher assembly defined in part by portions of an elongated tube joined together to define a gap. A pusher is slideably mounted within the gap and biased to push fasteners toward the nose of the nailer. The magazine also includes a fastener track that includes a reduced portion and an enlarged portion to accommodate fasteners of different sizes. A shoe may be releasably attached to the bottom portion of the magazine and in one embodiment is V-shaped including a raised portion at one end. In another embodiment the shoe has a flat workpiece engagement portion.
