摘要： A line trimmer head is provided including a rotatable drive shaft and a housing mounted to the drive shaft for rotation therewith. The housing has an open end and at least one peripheral aperture formed through the housing. A spool subassembly is positioned at least partially within the housing adjacent the open end of the housing. The subassembly includes a spool having at least one flange extending radially outwardly from the periphery thereof, a cog ring secured to the spool, and a ratchet and pawl assembly formed between the cog ring and spool. The ratchet and pawl assembly allows rotation of the spool in a first direction with respect to the cog ring for winding line around the spool while preventing spool rotation in a second direction opposite the first direction to facilitate line feed bumping and line trimming operations.

摘要： A hand held power tool is disclosed comprising an internal combustion engine, a workpiece driven by the engine, a boom extending between the engine and the workpiece, and an actuator for a kill switch of the engine. The actuator includes a collar disposed around the boom, a fingerpiece connected to the collar and movable with the collar between a first position and a second position, and an extension depending from the collar. Preferably, the fingerpiece and the kill switch are disposed on opposite sides a horizontal plane bisecting the boom. The extension engages the kill switch such that when the fingerpiece is moved to the second position, the kill switch interrupts the flow of electricity to the spark plug. Preferably, the collar, fingerpiece and extension being formed as a unitary piece.

摘要： Parallel tube type, gasoline powered, blower/vacuums with improved versatility are provided. In one possible feature, a flapper throttle adjacent to the housing for controlling the engine is pivotable from side-to-side with respect to an elongate handle. The elongate handle is sufficiently long to allow a plurality of gripping positions, while the flapper throttle is sufficiently long to allow the operator to access the flapper throttle from different gripping positions on the handle. In another possible feature, a pivotable lever throttle is provided at an interface of the handle forward portion and a transverse grip portion at the handle forward portion end. The lever throttle has a first end accessible to the operator when gripping the transverse grip portion, and a second end accessible to the operator when gripping the handle forward portion. In another possible feature, a blower/vacuum is provided with a rear handle that increases blower/vacuum versatility in that the operator has a plurality of gripping choices available to him.
摘要翻译：提供平行管式，汽油动力，提供多功能性的鼓风机/真空吸尘器。在一个可能的特征中，与用于控制发动机的壳体相邻的挡板节流阀可相对于细长的把手从一侧到另一侧枢转。细长手柄足够长以允许多个抓握位置，而挡板节流阀足够长以允许操作者从手柄上的不同夹持位置进入挡板节流阀。在另一个可能的特征中，可枢转的杠杆节流阀设置在手柄向前部分的接口处，并且在手柄前部端部处设置有横向抓握部分。杠杆节流阀具有在抓握横向抓握部分时操作者可接近的第一端，以及当抓握手柄前部时操作者可接近的第二端。在另一个可能的特征中，鼓风机/真空机设置有后把手，其提高鼓风机/真空多功能性，因为操作者具有可用于他的多个夹紧选择。

摘要： A line trimmer head (10) includes a line feed configuration which facilitates reloading the head (10) with new line without requiring removal of the spool (24) from the housing. Line (18) is sequentially fed first into the housing through a peripheral opening (20) in the housing, through a guide channel (84, 86) in the spool, and then out of the housing beyond a lower flange (26) of the spool through an opening in the hub (98) of the spool. Finally, the line is fed into a small opening in a spool flange (94) to secure the line with respect to the spool. Rotation of the spool then 46 causes the line to be drawn into the housing through the peripheral opening and wrapped around the spool. The spool provides separate storage compartments (38, 40) for different lines. Additional payout of line is provided when a bump knob is bumped on the ground surface.

摘要： A plastic plug for protecting an electric cord from damage during shipping when such cord is shipped within separated rigid tubular components of a handle, or the like, comprises two semi-cylindrical half portions of a plug which are pivotally united along axially extending side edges of the half portions. With its half portions pivoted together, the plug defines a channel for leading the electric cord out of, or into either end of its associated rigid tubular component without contact between the cord and the adjacent end edge surface of the rigid tubular component.
