| 20080202292 | Apparatus for use in and method of setting the tension in a drive belt of a motorcycle - A specially configured wrench is fitted to the fork structure of the rear wheel of a motorcycle to transmit rotational torque to the axle and move the rear wheel axle and sprocket to adjust and accurately set the tension in the drive belt of the motorcycle to a desired level. Further, a method is disclosed for reducing slack, changing, and/or setting a desired tension in the flexible power transmission mechanism of a motorcycle, the mechanism exemplified by a chain or drive belt having upper and lower reaches wrapped about respective of a rotatable forward motor drive sprocket and a rotatable rear wheel drive sprocket and used in cooperation with a fork structure for mounting the rear wheel and a cam-operated structure for repositioning the rear sprocket and associated axle. | 08-28-2008 |
| 20080289451 | Mechanized Wrench Adapter - A box wrench, also known as a ring spanner, to tighten or loosen nuts and bolts that can be attached to a screwdriver capable of taking different screwdriver bits or to a power tool such as a cordless screwdriver, corded screwdriver, pneumatic wrench etc. | 11-27-2008 |
| 20090090220 | REMOTE OPERATED CLOSED-END WRENCH - A powered wrench is configured to rotate fasteners and includes a drive and a closed-end wrench. The closed-end wrench includes a wrench case, a socket rotatably mounted in the case, and a driveshaft rotatably mounted in the case and attached to the drive. The driveshaft includes a worm gear drivingly connected to a toothed external face of the socket so that rotation of the driveshaft by the pneumatic drive causes rotation of the socket. | 04-09-2009 |
| 20090126535 | POWER WRENCH - A power wrench includes a body, a connecting element, a drive motor and a protection circuit. The connecting element is axially rotatably disposed inside the body and protrudes out of the body. The drive motor is for rotating the connecting element. The protection circuit is for controlling a power supply of the drive motor according to a value of a drive current of the drive motor. When the drive current of the drive motor is over a critical current value, the power supply of the drive motor is cut off. | 05-21-2009 |
| 20100288081 | LOW PROFILE WRENCH - A wrench for rotating a member comprises an elongate body having a head portion. The wrench may include a drive mechanism mounted to the head portion. The drive mechanism may comprise a drive gear and a clutch gear. The drive gear may include a drive element for engaging the member. The clutch gear may be operatively coupled to the drive gear and may be rotatably supported by a unidirectional roller clutch. | 11-18-2010 |
| 20120260776 | SOCKET AND HANDLE TOOL SET - A socket and handle tool set facilitates the access of the socket to an obstructed fastener. Each socket provides a fastener receptacle to grip the fastener upon which the socket operates. Each socket splits open vertically along a vertical hinge. Specific embodiments provide a selectively latchable and unlatchable socket latch. Gear teeth are disposed around the circumference of at least a portion of the external perimeter of each socket. The gear teeth engage complimentary gear teeth that are disposed within the handle of the handle component of the tool set. The handle provides a socket holder and a socket drive mechanism disposed in the socket holder to engage the gear teeth of the socket. Additionally, the handle component of the tool set provides a driver tool receptacle distal from the socket handle to receive a driver tool to operate the socket drive mechanism. | 10-18-2012 |
| 20140190315 | Gear head socket tool - A non-ratcheting socket tool for loosening or tightening nuts or bolts, especially when the nut or bolt head is located in a crowded area where there is inadequate space to pivot or rotate a handle of a wrench or ratchet. The gear head socket tool includes a slim streamlined housing including a straight beveled gear coaxially arranged around a sleeve or ring having a plurality of internal nut/bolt gripping wrench teeth, wherein the straight beveled gear teeth mate with beveled pinion gear teeth perpendicular thereto. An extension bar is inserted into the end of the gear head housing perpendicular to the gear head. Rotation of the extension bar with a ratchet, a breaker bar, strong arm or a power tool such as a pneumatic or electric impact wrench, or drill motor provides perpendicular torque to drive the gear head socket rotating the teeth turning the nut or bolt. | 07-10-2014 |
| 20150027276 | WRENCH - A wrench includes a body having a working end which has a first toothed portion, a first room, a second room, a third room and a first pivot cavity. The second and third rooms open through the top of the body. A driving unit is pivotably connected to the working end and has a first recess and a second recess for receiving a first pawl and a second pawl therein. The first pawl has teeth engaged with the first toothed portion, and the second pawl has teeth engaged with a second toothed portion of a first teeth disk in the first room. A second teeth disk is pivotably located in the second room and has a forth toothed portion which is engaged with a third toothed portion of the first teeth disk. A shaft is pivotably located in the third room and is connected to the second teeth disk. | 01-29-2015 |
| 20160031067 | Mechanised Spanner - A mechanised spanner for driving a nut along a threaded rod includes a housing and a drivetrain. The drivetrain has an input shaft and an output member mounted for rotation within the housing. The input shaft rotates the output member during use. An insert is attachable to and rotatable with the output member of the drivetrain and has a jaw for receiving and engaging a nut. The insert is attachable to and rotatable with the output member by a clip, which clips to an insert retainer in the output member and includes an elongate member protruding from the insert which terminates in a detent. The insert retainer has a clip cavity and a moveable retaining wall for bearing against the detent of the clip; retaining the insert in the output member. The insert may be replaced with a different insert for receiving and engaging a nut with different dimensions. | 02-04-2016 |
