摘要： A spark unit for an internal combustion fastener-driving tool comprises a spark plug body mounted within a boss portion of the tool cylinder head, and a spark unit cathode electrode is mounted within the spark plug body in such a manner that the tip portion of the spark unit cathode electrode projects below or away from the bottom or under-surface portion of the cylinder head mounting boss. In this manner, the tip portion of the spark unit cathode electrode is not disposed within a recess or pocket region so as not to tend to accumulate dirt or oil deposits which can tend to foul or otherwise adversely affect the sparking and ignition charactreristics of the spark plug assembly and the operation of the fastener-driving tool.

摘要： A non-sealing, lubricating piston ring for lubricating the cylinder wall of a piston housing in a combustion tool is disclosed. The lubricating piston ring is made from a lubricating material such as polytetrofluroethylene (PTFE). The shape of the PTFE ring is designed to optimize the lubricity of the piston housing, while allowing enough friction for the piston to operate properly within the piston housing during reciprocating cycling movement. The PTFE ring may have radial fins extending from an outer surface thereof that are angled to promote ring rotations, such that the ring moves easily along and efficiently lubricates the inner cylinder wall of the piston housing. The PTFE ring does not form a seal between the piston and the housing. Instead, the PTFE ring is positioned above or below a sealing ring, such as a steel piston ring which forms the seal between the piston and the piston housing.
摘要翻译： 公开了一种用于润滑燃烧工具中的活塞壳体的气缸壁的非密封润滑活塞环。 润滑活塞环由诸如聚四氟乙烯（PTFE）的润滑材料制成。 PTFE环的形状被设计成优化活塞壳体的润滑性，同时允许足够的摩擦使活塞在往复循环运动期间在活塞壳体内适当地运行。 PTFE环可以具有从其外表面延伸的径向翅片，其具有成角度以促进环形旋转，使得环容易地沿着并有效地润滑活塞壳体的内筒壁。 PTFE环不会在活塞和外壳之间形成密封。 相反，PTFE环位于密封环的上方或下方，例如在活塞和活塞壳体之间形成密封的钢活塞环。

摘要： A fastener driving tool includes a power source including a cylinder, a piston with a driver blade reciprocating in the cylinder, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, and a magazine housing a supply of the fasteners. A magazine feeder mechanism is associated with the magazine for sequentially feeding fasteners into the nose, and the feeder mechanism includes a reciprocating feed piston. A conduit is connected between a port in the cylinder and the feed mechanism for diverting combusted gas for activating the feed piston. The port is disposed in the cylinder a specified distance below a piston prefiring position, and the distance is reflective of a delay of feeding the gas to the feed piston at least until engagement between an end of the driver blade and a head of a fastener in the tool nose.

摘要： The front idler roller of the belt sander is mounted by a yoke for swinging movement in a plane containing the axes of both the drive and idler rollers and for shifting movement along a path generally toward and away from the drive roller. A transversely disposed shaft mounted by the tool housing has a cam formation at one end thereof received within an opening formed in the yoke; the cam is captured in this opening formed in part by a cam follower. The shaft is mounted for axial and rotational movements. Rotation of a first knob on the other end of the shaft causes the latter to move axially thereby to swing the idler roller for centering of the belt. Rotation of a second knob, concentric with the first knob and also mounted on other other end of the shaft, causes the shaft to rotate thereby activating the cam for shifting the idler roller toward the rear roller for easy belt replacement.
