  • Patent number: 5560480
    Abstract: A socket holder for a set of wrench sockets can be magnetically attached to any metal surface while firmly securing the sockets therein. The socket holder has individual sleeves, each capable of receiving a socket, and a radial contracting member secured to each sleeve within the holder for the purpose of gripping the socket as it is placed within the sleeve. In one embodiment of the invention, the radial contracting member is in the form of a resilient gasket attached to the inner walls of each sleeve. In another embodiment of the invention, the radial contracting member is a foam pad secured between the outer shell and a spacer plate, wherein the foam pad has pre-cut holes to align with the socket holder sleeves.

  • Patent number: 4991470
    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. A reversing ratchet mechanism is employed to lock the drive shaft. The specific construction and arrangement of components provides a socket wrench has been found to substantially reduce the work required to remove nuts or bolts, as compared with conventional wrenches. The present invention provides an improved T-handle for use with a tool having a shaft which rotates about its longitudinal axis.

  • Patent number: 4680994
    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.
