| 173164000 | Means to hold and relatively rotate sections of tool shaft | 6 |
| 20090126960 | Portable Power Tool with Drive Shaft Lock Means - A portable power tool with a rotation motor ( | 05-21-2009 |
| 20100200258 | TOOL WRENCH ASSEMBLY - A tool wrench assembly for a blasthole drill includes a fork pivotally fixed relative to at least one actuator that moves the fork between an engaged and a disengaged position. | 08-12-2010 |
| 20100224382 | NOISE ELIMINATION BRAKE FOR AUTOMATIC SPINDLE LOCKING MECHANISM - A rotary power tool of the invention has a motor, a motor shaft driven by the motor, an output shaft coupled to the motor shaft via an automatic spindle locking mechanism, a housing portion surrounding the output shaft, and a braking member that is non-rotatable relative to the housing portion. The braking member exercises a braking torque on the output shaft whenever it rotates. | 09-09-2010 |
| 20100252292 | SPINDLE LOCKING ASSEMBLY - A locking assembly for the spindle of a tool includes a locking member, a biasing member interconnected with the locking member, and a collar surrounding a portion of the spindle. The spindle includes a spindle slot that receives the locking member to lock the spindle with respect to the tool housing. The collar may be rotated into an unlocked position in which the biasing member holds the locking member out of engagement with the spindle slot. The collar may also be rotated into a locked position in which a cam surface in the collar acts on the biasing member to apply a biasing force on the locking member toward engagement with the spindle slot. The biasing member may deflect to accommodate rotation of the collar into the locked position with the spindle slot not aligned with the locking member. | 10-07-2010 |
| 20110214892 | HAND-HELD MACHINE TOOL HAVING AUTOMATIC SHAFT LOCKING - A hand-held machine tool device, in particular, for a screwdriver ( | 09-08-2011 |
| 20160059401 | POWER TOOL - It is an object to provide a novel technique for releasing an intervening member of a driving member. A representative screwdriver is provided with a motor and a driving mechanism. The driving mechanism has a spindle, a lock sleeve, rollers, a driving gear, a retainer and a spring receiver. When driven with the rollers held between the lock sleeve and the driving gear, the spindle is rotated in a normal direction. The lock sleeve has an inclined part and the retainer has an inclined part. The lock sleeve and the retainer move with respect to each other in the axial direction and the circumferential direction by sliding contact between the inclined parts. This relative movement in the circumferential direction is utilized to release the holding of the rollers. | 03-03-2016 |
