摘要： A viewing window for covering an aperture in a hand-held circular saw includes an optically transmissive member adapted to be coupled with the guard. The member is movable between a closed position, wherein the member substantially covers the aperture, and the open position, wherein the member at least partially uncovers the aperture, to allow the cleaning of the member. A structure is provided for biasing the member to the closed position.

摘要： A nozzle assembly for a power tool that generates dust includes a housing surrounding a portion of the power tool, an outlet section of the housing for accommodating the flow of dust away from the power tool and a conduit that is coupled with the outlet section to direct the flow of dust from the housing. During operation of the power tool, the conduit is rigidly coupled with the outlet section in an advanced position in which rotational movement of the conduit relative to the outlet section is impeded. The direction of dust flow out of the conduit may be selectively adjusted by transferring the assembly to a retracted position in which rotational movement of the conduit relative to the outlet section is substantially unimpeded. The outlet section and conduit may be tapered so that the advanced position is obtained through a friction fit. A preferred embodiment of the present invention further includes an arcuate channel disposed along the circumference of the conduit, a tab protruding from the housing and disposed within the channel to couple the conduit with the outlet section, a detent intermediate the channel and the inlet end of the conduit and a flexible collar intermediate the housing and the conduit. The nozzle assembly may also include a dust collection container coupled with the conduit.
摘要翻译： 用于产生灰尘的电动工具的喷嘴组件包括围绕电动工具的一部分的壳体，壳体的出口部分，用于容纳灰尘远离电动工具的流动，以及与出口部分联接以引导 来自外壳的灰尘流动。 在电动工具的操作期间，导管与出口部分刚性联接在一个先进位置，在该位置，管道相对于出口部分的旋转运动被阻碍。 可以通过将组件转移到缩回位置来选择性地调节从管道流出的灰尘的方向，其中导管相对于出口部分的旋转运动基本上不受阻碍。 出口部分和导管可以是锥形的，使得通过摩擦配合获得前进位置。 本发明的优选实施例还包括沿导管圆周布置的弓形通道，从壳体突出并设置在通道内以将导管与出口部分连接的突出部分，通道和入口端的入口端 导管和位于壳体和导管之间的柔性套环。 喷嘴组件还可以包括与导管连接的灰尘收集容器。

摘要： A window assembly is provided for use on a hand-held circular saw. The window assembly has a transparent member that is attached to an upper guard of the saw in a covering relationship with an aperture provided in the upper guard. A projecting rib is provided that is coupled to and which extends outwardly from the guard adjacent the forward edge of the transparent member. The projecting rib substantially prevents light emanating forwardly of the saw from reflecting off of the member.

摘要： A switch lockout mechanism for a power tool includes a handle housing for gripping by a power tool operator. The handle housing is generally elongated in a direction corresponding to the gripping axis of a power tool operator. A switch is attached to the housing and is actuatable between an “on” position and an “off” position. A locking member is rotatably or pivotally attached to the housing. The locking member is rotatable about an axis that generally extends in the same direction as the handle housing in an elongated direction. The locking member has a first rotatable position wherein the switch is locked in its “off” position, and a second rotatable position wherein the switch is actuated to its “on” position. An actuating member allows a tool operator to move the locking member between its first and second positions.

摘要： A high speed thrust bearing assembly is provided for use on a hand-held circular saw. The thrust bearing assembly is held in place within a plastic housing which has a through hole therethrough. The plastic housing further has a first counterbore which is larger than the through hole, and a second counterbore which is larger than the first counterbore. A high speed thrust plate is placed within the plastic housing. The thrust plate has a flange section and a bearing section. The bearing section has an indentation therein. The thrust plate is placed within the plastic housing so that the bearing section is disposed through the through hole of the plastic housing with the flange section being held within the first counterbore. A sleeve bearing is thereafter placed within the second counterbore and surrounds a rotating shaft. The rotating shaft has a terminal end with a cylindrical projection thereon which matingly fits within the indentation of the bearing section in the thrust plate.

摘要： A receptacle (74) in the shoe (12) of a circular saw (14) holds an accessory tool (10) which combines the functions of blade wrench and square. The base (18) of the L-shaped tool (10) is bent to provide an offset bearing surface (52) to facilitate its use as a square. The base (18) also includes a hexagonal wrench opening (46) sized to fit the saw blade retaining nut (48). An interrupted longitudinal groove (26) in the "upright" portion (16) of the L helps guide the tool (10) into the receptacle (74) and hold it there.
