摘要： Several embodiments of tachometers generators for use in controlling the speed of electrical motor driven tools. In each embodiment a toothed rotor (28, 52, 72, 92, 122) is fixed for rotation with the motor armature shaft (23, 53, 73, 93, 124) and a sensor (31, 55, 75, 96, 126) is juxtaposed to the rotor. The sensor is comprised of a core (32, 56, 76, 98, 127) having a first end portion (33, 57, 77, 99, 128) juxtaposed at a first location relative to the rotor and a second end portion (36, 58, 78, 101, 129) that is juxtaposed to the rotor at a second, spaced location. A permanent magnet (37, 59, 79, 102, 131) is interposed between the second end portion and the rotor with one of its poles aligned with a second end portion and the other of its poles aligned with the rotor. A coil (38, 61, 81, 103, 132) is wound around an intermediate portion (34, 62, 82, adjacent 99, adjacent 128) of the core so that a voltage will be generated in the coil by the alternating magnetic flux passing through the core during rotation of the rotor, which voltage is indicative of the speed of the armature shaft. The compact construction facilitates installation in close places and the device provides a strong signal and exhibits a high signal to noise ratio.

摘要： The invention is directed to a cutterhead for a portable power planer. The cutterhead includes a cylindrical body having a substantially cylindrical surface and defining a rotational axis about which the cylindrical body rotates during normal operation of the power planer. A solid elongated cutting member is provided and has a channel formed therein to define at least two cutting edges. The cylindrical body has an elongated recess formed therein for holding the cutting member. The recess extends in a direction parallel to the rotational axis of the cutterhead and defines a longitudinal aperture in the surface for accommodating one of the cutting edges. The recess has a recess wall extending inwardly away from the aperture to surround and hold the cutting member against the centrifugal forces acting thereupon during the rotation of the cylindrical body. Positioning pins arranged in the cylindrical body engage the cutting bar to angularly fix the cutting member so that the one cutting edge penetrates the aperture at a predetermined angle of elevation with respect to the surface of the cylindrical body. A screw mounted in the cylindrical body directly engages the cutting member to tightly seat the latter against the recess wall.

摘要： The invention is directed to a foldable, portable workbench having a work table and a support structure for supporting the work table. The support structure includes a pair of mutually spaced leg assemblies and each of these leg assemblies, in turn, includes a pair of legs pivotally connected at one end thereof to the work table. Articulated linkages pivotally interconnect, respectively, the two legs of each pair of legs to each other and at least one of the legs to the work table. The articulating linkages are connected so that the work table and leg structures are stacked in juxtaposition to each other when the workbench is in its folded position and, so that the other ends of the leg structures are spread apart from each other with the work table substantially transverse to the leg structures when the workbench is in the erected position.

摘要： The invention is directed to a chuck for grasping a tool such as a drill bit or the like and adapted to be tightened with the aid of a chuck key. The chuck includes a hollow body defining a longitudinal axis and having a front end for receiving the tool therein. A plurality of elongated jaws are movably mounted in the hollow body. A sleeve is rotatably mounted on the body and threadably engages the jaws to move the jaws in the body to clamp and release the tool whereby substantial radial forces are transmitted to the body by the jaws when the jaws are tightened on the tool. The sleeve extends in the direction of the longitudinal axis of the hollow body to surround the hollow body at the region of the jaws for supporting the body against the radial forces. A gear is provided for coacting with the chuck key to actuate the sleeve to move the jaws for tightening the jaws on the tool.

摘要： A radial arm of a radial arm saw comprises a lightweight metal casting of inverted U cross-section and having opposing longitudinal grooves in the inner faces of the side walls of the inverted U. A metal strip of resilient arcuate cross-section is press fitted into each groove to form guides for supporting and guiding a power saw unit movable along the radial arm. The lighter weight of the radial arm is particularly advantageous for a portable radial arm saw, and the inserted metal strips form inexpensive durable guides.

摘要： The invention is directed to a disconnect and overload bypass arrangement for a hand-held portable tool equipped with an electric motor supplied from a source of electrical energy and a manually operable on-off switch for switching the tool on and off. The arrangement includes a self-reclosing disconnect switch operatively connected to the motor to temporarily disconnect the same from the energy source in response to an overload condition; and, circuit control means for supplying energy to the motor at a reduced level when the disconnect switch is open whereby the motor will continue to operate at reduced torque pending self-reclosure of the disconnect switch and thereby provide the operator of the tool with an audible and visual indication that the motor has not been deactivated by manually actuating the on-off switch.

摘要： A portable machine tool, comprising a base structure, a work surface supported by the base structure for supporting, in use, a workpiece, and a column pivotally connected to the base structure and being pivotal between an upstanding operative position in which the column extends upwardly above the work surface and a lateral inoperative position. An operating unit is attached to the column and is supported thereby above the work surface in the operative upstanding position for operating, in use, on the workpiece. A locking arrangement releasably secures the column in the operative upstanding position. Preferably the column is pivoted behind and to the rear of the base structure, and a part of the work surface is removable to expose a space inside the base structure in which the operating unit is at least partially housed when the column is pivoted to the inoperative lateral position. In this way the machine tool, which is preferably a radial arm saw, is made more compact for transporting and/or storage.
