摘要： A chop saw pivotably mounted for movement between a raised rest position and a lowered operational position, having a motor driven saw-blade rotatably supported about a shaft, with a saw housing partially encasing the saw-blade and a swinging blade guard which covers the exposed segment of the saw-blade when the saw is in the rest position. When the saw is lowered to its operational position, a linkage system comprising four effective levers and four hinges clears the blade guard, thereby exposing the saw blade to the work piece. To accommodate changing the saw blade while the saw-unit is in its rest position, the effective length of one of the levers can be temporarily reduced, thereby clearing the blade guard from the exposed section of the saw blade. This provides easy access to the saw-blade to be changed.

摘要： A power tool comprising a housing displaceably mounted to a foot plate, a blade, a motor, an electric switch and an interlock for controlling movement of the housing with respect to the foot plate. The interlock has a control button mounted to one of the housing or foot plate which cooperates with a channel fixed in relation to the other of the housing or foot plate. The control button can select between a plunge cut mode wherein the blade can protrude below the foot plate, or a blade change mode wherein the blade is prepared for a blade change operation. The channel comprises a major leg in communication with a minor leg. Cooperation between the button and the major leg selects the plunge cut mode. Cooperation between the button and the minor leg selects the blade change mode. The interlock may also comprise a housing lock and a spindle lock.

摘要： A drilling and/or hammering tool which includes a hollow spindle (1) and a tool holder (10) that can be attached to an end (18) of the spindle and removed therefrom. The toll holder comprises a tool holder body (14) which can be fitted within the end of the spindle and releaseably locked therein by means of at least one locking element (32) and a locking ring (42) for releasably holding the or each locking element in a locked position in which the locking element(s) lock(s) the tool holder to the spindle. The tool holder (10) comprises a manually actuable sleeve (40) for rotating the locking ring (42) in a first direction and for rotating the tool holder body (14) in a second opposite direction, and resilient means (62) for urging the tool holder body to follow the movement of the locking ring in the first direction and the locking ring to follow the movement of the tool holder body in the second direction. The resilient means urges the locking ring and the tool holder body into relative rotational positions in which the locking ring (42) holds the or each locking element in the locked position. The locking ring (42) has an internal radius that varies along its circumference so that rotation of the locking ring about the axis of the tool holder body will move it between a locking position in which it causes the or each locking element (32) to retain the toll holder body in the spindle, and a release position in which it will allow the or each locking element to move radially to release the tool holder body.

摘要： An electric motor driven hand-held tool, such as a drilling, hammering or screw driving tool having a tool housing within which is located an integrated switch unit (6). The switch unit (6) includes an electronic motor control unit (8), a first actuator which is actuated by a manually operable power member (4) and to which the control unit is responsive to power the motor and a second actuator (10) which is actuated by a manually operable forward/reverse member (14) and to which the control unit is responsive to drive the motor in a selected forward or reverse direction. The forward/reverse member (14) is located remotely from the switch unit (6) on a portion of the tool housing which can be seen by a user of the tool during normal operation of the tool. To facilitate this a linkage arrangement (16) is provided for actuating the second actuator (10) in response to a manual actuation of the forward/reverse member (14). The linkage (16) is pivotally mounted on a closed end of a jam pot motor casing (3). The linkage comprises a central annular portion (18) pivotally mounted on a boss (4) formed on the motor housing (3), a first upwardly extending arm (20) on which the forward/reverse lever (14) is formed and a second downwardly extending arm (22) which engages the second actuator (10).

摘要： A dust extraction shroud for a drill, which surrounds a drill bit and which lies adjacent the work surface, comprises a body portion defining a first inlet adapted to engage the work surface and to surround the location at which said bit penetrates the surface. The shroud body further defines a first outlet connected to a source of suction and a third inlet for allowing the bit to pass through said body portion. A first sealing means is arranged in said third inlet for surrounding said bit and resisting the flow of air. Wherein said body portion includes at least one protruding portion defining a second inlet between said protruding portion and an adjacent part of said body, and on a side of said protruding portion remote from the first inlet. The second inlet admits air to enter said body portion and travel to the first outlet.

摘要： A chop saw has a saw unit connected pivotally about a horizontal axis to a turntable mounted rotatably in a base plate about a vertical axis. An indexing mechanism for locating rotational positions of the turntable comprises catch recesses on the underside of the turntable along a circular arc. A leaf spring is mounted on the base plate and has a free end engageable in the catch recesses upon rotation of the turntable. A release element is movably mounted in the base plate and operable to flex the leaf spring to move the free end thereof out of engagement with any catch recess engaged thereby. Advantageously the leaf spring and the base plate may be integrally molded or cast. Also, the catch recesses may conveniently be formed during casting or molding of the turntable.

摘要： A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, a piston slideably mounted within the housing, a drive mechanism that converts rotary output of the motor into a reciprocating motion of the piston, a ram slideably mounted forward of the piston and that is reciprocatingly driven by the piston, and a beat piece support mounted in the housing forward of the ram. A beat piece is slideably supported by the beat piece support. The beat piece is repetitively struck by the ram and that in turn repetitively strikes an end of a tool when the tool is held in the tool holder to transfer the momentum of the ram to a tool. The beat piece support includes a seal that is slidingly engaged by the beat piece. The seal includes an absorbent material.
