    摘要: A portable electric drill including a housing having a motor driven chuck rotatably supported thereon. The chuck is the conventional jaw-type which utilizes a key to open and close the jaws and secure a tool bit therein. A lever on the housing is movable to turn the motor on and rotate the chuck and tool bit, and a novel guard on the housing prevents the chuck from turning should the lever be actuated when the key is in place.

    摘要: A safety lock comprises a locking member (26, 28) which engages a support. An inner lock shaft (30a) actuates the locking member, the inner lock shaft having a first coupling face (35a) at one end thereof. An outer lock shaft (30b) has a second coupling face (35b) which engages the first coupling face when the inner lock shaft and the outer lock shaft are in respective engagement positions relative to each other. A coupling structure (18) moves to prevent engagement of said first coupling face with said second coupling face.

    摘要: A lathe or other rotating machine includes a chuck for holding a work piece or tool. The chuck is operated between engaging and disengaging positions by rotating a chuck key that has been inserted into a key receiving opening in the chuck. A chuck key docking station on the machine includes a sensor to sense the presence or absence of the chuck key at the docking station. The sensor is connected to prevent operation of the machine at speed if the chuck key is not sensed in the chuck key docking station.

    摘要: A radial arm saw guard with operational interlock and adjustable outfeed user barrier is disclosed. The radial saw includes a motor driven saw blade that is mounted on a yoke depending from a supporting arm that overhangs a worktable. The motor driven saw blade is movable relative to a worktable mounted fence in order to enable the motor driven saw blade to be operated for rip cutting of workpieces longitudinally relative to the fence and for cross cutting transverse relative to the fence. A blade guard is mounted in fixed position relative to the yoke for covering at least approximately an upper half of the motor driven saw blade. An adjustable outfeed user barrier is mounted to the upper blade guard for operation between an upper disengaged position exposing the motor driven saw blade and a lower engaged position covering an outfeed end of the motor driven saw blade to protect a user during rip cutting. An interlock prevents rip cutting by the motor driven saw blade unless the adjustable outfeed user barrier is in its lower engaged position. The adjustable outfeed user barrier, in addition to being adjustable for workpieces of different thickness, is also adjustable for accommodating motor driven saw blades of different diameter.
