摘要： A miter saw clamp accessory to facilitate vertical and/or horizontal clamping of a workpiece against a supporting worktable and fence is disclosed. The miter saw clamp accessory includes a pair of extension rods extending laterally outwardly from one end of a frame with a clamp support mounted on such extension rods. A clamp shaft is adapted to be mounted in a top opening of the clamp support for vertical clamping or in a side opening of the clamp support for horizontal clamping of the workpiece. A clamp assembly is mounted on the clamp shaft and includes a connecting arm for adjustable mounting of a clamping arm having a workpiece clamp at one end that is arranged for confronting opposed positioning relative to the frame for vertical clamping or to the fence for horizontal clamping of the workpiece. A miter saw crown molding jig accessory is also disclosed for mounting on a miter saw frame. This accessory includes a shaft mounted immediately adjacent to the worktable fence and a clamp head that is adjustably mounted on the shaft and includes a vertically extending bearing surface and a horizontally extending upper shoulder which overhangs the vertically extending bearing surface. The clamp head is moved on the shaft until the horizontally extending upper shoulder rests on a top edge of the crown molding while the vertically extending bearing surface engages a side edge of the crown molding in alignment with the worktable fence.

摘要： A ceiling fan with retractable fan blades includes an electric motor operable to spin a rotor with a plurality of fan blades attached thereto. Each of the fan blades is operable to move between a closed position and an open position. A rotatable center ring is included on the rotor and connecting rods join each fan blade to the center ring. Rotation of the center ring relative to the rotor moves the plurality of connecting rods and fan blades in unison. The fan blades are spring biased toward the closed position. When the rotor rotates, centrifugal forces acting on the fan blades overcome the spring biasing forces and cause the fan blades to move toward the open position. A governor is positioned between the rotor and at least one of the fan blades to limit the speed of movement of the fan blades between the closed position and the open position. The governor may take the form of a fluid cylinder.
摘要翻译： 具有可收缩风扇叶片的吊扇包括电动马达，其可操作以旋转具有附接到其上的多个风扇叶片的转子。 每个风扇叶片可操作以在关闭位置和打开位置之间移动。 转子上包括一个可旋转的中心环，连接杆将每个风扇叶片连接到中心环。 中心环相对于转子的旋转一致地移动多个连接杆和风扇叶片。 风扇叶片被弹簧偏压到关闭位置。 当转子旋转时，作用在风扇叶片上的离心力克服弹簧偏压力，并使风扇叶片向打开位置移动。 调速器位于转子和至少一个风扇叶片之间，以限制风扇叶片在关闭位置和打开位置之间的移动速度。 调速器可以采取液压缸的形式。

摘要： A compound miter saw with an adjustable/bypassable bevel stop is disclosed. The compound miter saw includes a turntable rotatably mounted on a supporting frame. A power driven saw blade is pivotally mounted to the turntable and moves along a predetermined path from an upper raised to a lower operational position that includes a saw blade slot in the turntable. A bevel adjusting features selectively rotates the power driven saw blade relative to the turntable. The adjustable/bypassable bevel stop includes predetermined bevel stop settings at set angles, for example, such as 0.degree. and 45.degree., as well as an over-riding feature when angles either less than or greater than the predetermined bevel stop settings are desired. The over-riding feature does not require re-adjustment of the predetermined bevel stop settings.
摘要翻译： 公开了具有可调节/可旁路斜面止动件的复合斜切锯。 复合斜切锯包括可旋转地安装在支撑框架上的转台。 动力驱动锯片可转动地安装在转台上，并沿预定路径从上升高到下运行位置运动，该位置包括在转台中的锯片槽。 斜面调整功能选择性地使动力驱动锯片相对于转台旋转。 可调节/可旁路的斜角止挡包括设定角度的预定斜面停止设置，例如0°和45°，以及当希望小于或大于预定的斜面停止设置的角度时的过载特征。 超越功能不需要重新调整预定的斜角停止设置。

摘要： A switch lock-out device to prevent unintended operation of a power tool through inadvertent actuation of a trigger operably associated with a motor as disclosed. The trigger is pivotally mounted in handle grip for energizing the power tool when depressed. An outer free end of the trigger extends within the handle grip. The switch lock-out device includes an integral multiple-armed element that is pivotally mounted within the handle grip. The pivotally mounted multiple-armed element includes a first arm that engages the outer free end of the trigger to prevent actuation, a second arm that includes a manual engageable button that extends outside of the handle grip and a third arm that engages an internal wall of the handle grip in biased and resilient engagement. When the manually engageable button is depressed, a first arm of the multiple-armed element is pivoted out of engagement with the free end of the trigger for actuation of the trigger to operate the power tool. Subsequent release of the manually engageable button enables the third arm biased against an internal wall of a handle grip to return the second arm and its manually engageable button to its normal position for subsequent re-engagement with the free end of the trigger when released.
摘要翻译： 一种开关锁定装置，用于通过无意识地操作与所述电动机相关联的触发器的触发器来防止电动工具的意外操作。 触发器枢转地安装在把手把手中，以在按压时对电动工具进行激励。 触发器的外部自由端在手柄柄内延伸。 开关锁定装置包括枢转地安装在把手把手内的整体多臂元件。 枢转安装的多臂元件包括与触发器的外部自由端接合以防止致动的第一臂，包括延伸到手柄把手外部的手动接合按钮的第二臂和与手柄接合的第三臂 手柄处于偏置和弹性接合。 当可手动接合的按钮被按下时，多臂组件的第一臂与触发器的自由端枢转脱离接合以致动触发器以操作电动工具。 手动接合按钮的随后的释放使得能够将第三臂偏置在手柄的内壁上，以将第二臂和其可手动接合的按钮返回到其正常位置，以便随后在释放时与触发器的自由端重新接合。
