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 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 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： 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 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 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.

摘要： A double-insulated portable electric tool has a housing with a pistol-grip switch handle portion and a switch cover portion removably secured to the switch handle portion forwardly thereof. An electric switch is mounted on the back of the cover and is provided with an actuating member. A trigger is mounted on the front of the cover and is coupled to the switch actuating member. The switch is accessible only upon removal of the switch cover from the switch handle; and even unauthorized removal of the trigger will not render the switch accessible. As a result, the switch may be replaced easily without an inadvertent interference with the double-insulating feature of the tool.
