Description: |
| Abstract: "A speed socket wrench which substantially reduces the work required to remove nuts or bolts is disclosed. The wrench includes a bevel gear and mating bevel pinion mounted respectively on a gear shaft and pinion shaft. A drive shaft is provided on the outer end of the pinion shaft. Interlocking cap elements are provided on the outer end of the drive shaft for releasably locking the drive shaft to prevent rotation thereof. In one embodiment, the cap elements include inner and outer caps which cooperate to provide a locking mechanism. In the locked position of the caps, the wrench can be employed as would any conventional wrench. In the unlocked position, a handle on the outer end of the gear shaft is rotatable by hand, resulting in revolving of the drive shaft. The gears of the present wrench turn freely in either direction and gear ratios and sizes can be varied with wrench size. In a further embodiment, a reversing ratchet mechanism is employed to lock the drive shaft."
