Adapters For Different-sized Fasteners Patents (Class 81/DIG11)
  • Patent number: 6138538
    Abstract: A finish-protective tool piece and a finish-protective tool piece collar are made from non-marring materials that circumferentially surround and secure a tool piece for rotating fasteners having driving heads. This collared tool piece or collar substantially protects against the marring and damaging of consumer item finishes during final stages of assembly by tool pieces skipping off the fastener heads during operation onto painted or otherwise finished surfaces. The collared tool piece or collar is being adapted for individual tool piece diameters or styles and rotates with the secured tool piece, said tool piece extending therethrough so as to be able to rotate the fastener. This invention has obvious cost advantages as it can prove useful in practically all aspects of consumer item manufacturing including automobiles, appliances, barbecues, furniture, bicycles, etc.

  • Patent number: 5806385
    Abstract: A universal socket is described which is suitable for use upon a myriad of fastening means whereupon at least a plurality of pins are capable of longitudinal axial movement in concert and in conformity with contact with a workpiece. This result is achieved by the incorporation of a biasing mechanism on the pins which biases the pins in a normally extended position, but which permits movement to a second retracted position. In one embodiment, the cross-sectional area of the pins is decreased in either a linear or non-linear manner from the outer periphery to the center of the socket. In operation, as the workpiece is inserted into the socket, the pins are moved in a longitudinal axial direction from their normally extended position to the second retracted position in conformity with the shape of the workpiece.

  • Patent number: 5791209
    Abstract: A self-forming socket having a plurality of retractable pins bundled in parallel within a housing is disclosed. The bundled pins may displace longitudinally and are biased by spring force away from a frame onto which the pins are slidably held. A spacer pin may be positioned at the center of the socket and is similarly biased away from the frame under spring force. When the socket is forced over a fastener, nut, or bolt head, groups of pins are pushed inward toward the frame and into the housing thereby conforming the pins to the contours of the fastener. Applying a torque to the socket transfers the torque through the bundled pins to the fastener. Each pin has a circular cross-section and the interior walls of the housing containing the bundled pins has a hexagonal shape and does not contain any right angles. The pins are packed in a hexagonal arrangement.

  • Patent number: 5157995
    Abstract: A tool having several coaxially disposed socket members housed within each other and corresponding to conventional sizes. The sockets are spring loaded, and each reduces its diameter towards the outer end that prevents the abutting sockets contained therein from falling off as a result of gravity or the spring force of the different spring members associated with each one of the sockets. The springs members urge these sockets outwardly, and the springs members of the sockets that are smaller than the head of the bolt or screw being matched are overcome and retracted, thereby the matching socket cooperatively engages with the head. Corresponding covers provide the necessary support area for the springs to exert their force against their corresponding socket members. An upper master socket assembly is removably mounted to the larger socket member, and it provides suitable engagement for a crank or lever to produce the necessary torque to rotate the socket members.
