    摘要： A pneumatic torqueing tool, particularly a pneumatic wrench, has a housing in which a pneumatic motor is mounted that is rotatable in two mutually opposite directions. A fluid conduit system is provided including a fluid passage which supplies pneumatic fluid to the motor when the same is to rotate in one of these directions. An adjustable throttle valve controls the flow of fluid through this passage and includes a valve member a portion of which is movable into and out of an orifice in the passage. A first arrangement mounts the valve member so that it can be gradually adjusted relative to the orifice whereby the portion of the valve member varies the effective cross section of the orifice. Another arrangement is provided for rapidly withdrawing the valve member with its portion entirely from the orifice in order to expose the maximum effective cross section thereof.

    摘要： A toy device which is a full-size replica of an electric power tool, particularly of a portable electric drill. Its housing is at least partially transparent to permit observation of the assembled parts and/or the operation of its motor which is connectable only to a source of low-voltage current. The tool spindle of the toy device can carry a chuck, a gear, a grinding wheel, a pulley or it can be connected to another torque transmitting or receiving component, for example, to the driven part of another toy device such as a toy saw, a toy grinder, a toy fan or the like. The housing of the toy device carries markings to facilitate the laying of conductors. When taken apart, the components of the toy device are stored in the compartments of a box.

    摘要： A SUPPORT FOR PORTABLE DRILLING MACHINES COMPRISES A COLUMN EXTENDING UPWARDLY FROM A WORK SUPPORTING BASE, A CLAMP MOVABLE ALONG THE COLUMN, AN ARM MOVABLE ALONG THE COLUMN WITH REFERENCE TO THE CLAMP AND HAVING MEANS FOR HOLDING A DRILLING MACHINES SO THAT THE TIP OF THE DRILLING TOOL EXTENDS TOWARD THE BASE, AND A FEED DEPTH SELECTING DEVICE INCLUDING AN EXTERNALLY THREADED GAGE IN A VERTICAL BORE OF THE ARM AND A LOCKING BOLT HAVING THREADS WHICH NORMALLY MATE WITH THE THREADS OF THE GAGE. THE BOLT CAN BE DISENGAGED FROM THE GAGE IN RESPONSE TO APPLICATION OF FINGER PRESSURE AND THE GAGE ABUTS AGAINST THE CLAMP WHEN THE ARM MOVES THE MACHINE TO THE LOWERMOST POSITION IN WHICH A WORKPIECE MOUNTED ON THE BASE IS FORMED WITH A HOLE OF DESIRED DEPTH. A SCALE ON THE ARM COOPERATES WITH AN INDEX ON THE CLAMP TO INDICATE THE POSITION OF THE ARM WITH REFERENCE TO THE CLAMP.

    摘要： A speed control arrangement for electrically operated power tools in which an electronic control circuit within the housing of the tool regulates the speed between no-load and full-load operation of the tool, so that the speed is held substantially constant. The rotor of the motor within the tool is mounted in combination with bevel gears so as to form an angle polishing machine for portable applications. A terminal block mounted within the handle of the portable tool interconnects the wiring between the motor and the electronic controlling circuit. The electronic circuit provides for the operation of the tool from a single-phase utility outlet, and will disconnect the motor from the line when the maximum allowable speed is exceeded.

    摘要： An electrical manicuring apparatus comprises a housing and a cover detachably connectable to the housing for closing an open end of the latter. A motor is arranged in the housing and receives its energy from a self-contained source of electrical energy. A plurality of manicuring tools are removably received in the cover and can be selectively connected with the output shaft of the motor when the cover is removed so that the device can then be used as a manicuring apparatus. In addition to this, the apparatus is provided with an electrically operated device on the cover which is operatively associated with the source of electrical energy when the cover is connected with the housing so that, in this connected state, the apparatus is usable for purposes other than manicuring, for instance as a flashlight or the like.
