Socket Holder

Номер: US20120096993A1
Автор: Edward Cigallio, Nicholas McCullough
Принадлежит: Individual

A socket holder may be designed as part of a socket extension or built into a socket holding end of a ratchet. The socket holder may have a mechanism to hold the socket at a conventional position. However, unlike conventional socket holders, the present invention may allow the socket to push past the holding mechanism, allowing the socket holder to fill an inside of the socket and provide pressure on the head of the bolt being applied by the socket. A magnet may be disposed on the end of the socket holder facing the bolt to help secure the bolt within the socket holder.

A method and a device are disclosed which seek to improve productivity of the installation of fasteners. This improved productivity is achieved by holding a fastener to a driving tool with a mechanical means for a substantial portion of an installation sequence to prevent nuisance disengagement between fasteners and their driving means including dropping of fasteners early in an installation cycle. The productivity of this fastener holding approach is best realized by allowing a streamlined operation with little interaction between the fastener driving device and an operator. Specifically, a fastener installation device is described which requires no direct manipulation of said device during the sequence of loading a fastener into said device, installation of said fastener with said device, disengagement of said device from said fastener to allow complete installation of said fastener, and loading a subsequent fastener.

An apparatus for rapid installation of threaded fasteners is provided. The apparatus includes a drive portion configured for being received by a rotary tool, a bit holder extending from the drive portion and configured for receiving a tool bit, the bit holder defining an elongate portion, and a sleeve configured for translatable movement along the elongate portion. The sleeve has a first extended position in which an end of the sleeve extends substantially beyond the tool bit and a retraction position in which the sleeve does not enclose the tool bit. A spring biases the sleeve into the extended position. Pressing of an end of the sleeve against a working surface imparts translation of the sleeve in a direction from the extended position towards the retracted position. 1. An apparatus for rapid installation of threaded fasteners , comprising:a drive portion configured for being received by a rotary tool;a bit holder extending from the drive portion and configured for receiving a bit driver, the bit holder defining an elongate portion;a sleeve configured for translatable movement along the elongate portion,a locking assembly carried by the sleeve and configured for locking the sleeve relative to the elongate portion;a cylinder extending outwardly around the sleeve, where the sleeve is rotatable relative to the elongate portion;wherein the sleeve has an unlocked extended position in which an end of the sleeve extends substantially beyond the bit driver and a locked retracted position in which the sleeve does not extend beyond an end of the bit driver and the sleeve is locked relative to the elongate portion by the locking assembly,wherein a spring biases the sleeve into the extended position,wherein the sleeve is placed in the locked position by rotation of the cylinder into engagement with the locking assembly;whereby pressing of an end of the sleeve against a working surface imparts translation of the sleeve in a direction from the extended position towards the ...

One embodiment of a fastener holding driver with a shank with a tip , further having a jaw assembly on the shank . The jaw assembly having a jaw , lock washers and lock washer springs . The fastener holding driver can hold a fastener rigidly to the tip 1. A fastener holding driver consisting of:a shank with a tip for engaging a fastener; one or more jaws;', 'one or more lock washers, said one or more lock washers engaging said shank; and', 'one or more lock washer springs, said one or more lock washer springs cause said one or more lock washers to be engaged with said shank; and, 'a Jaw assembly on said shank consisting ofone or more stops to limit the motion of said jaw assembly on said shank;wherein said jaw assembly holds a fastener rigidly on said tip.2. The fastener holding driver of claim 1 , wherein said one or more stops prevents said jaw assembly from being removed from said shank.3. The fastener holding driver of claim 1 , wherein the length of said jaw assembly can be changed to expose more of said shank.4. The fastener holding driver of claim 1 , wherein said lock washers do not rotate around said shank.5. The fastener holding driver of further having an element for manipulating said one or more lock washers and further having a spring to normally keep said element from contacting said one or more lock washers.6. The fastener holding driver of where part of said element extends into the side of said one or more lock washers that is towards said one or more jaws.7. A fastener holding driver consisting of:a shank with a tip for engaging a fastener; one or more jaws;', 'one or more lock washers, said one or more lock washers engaging said shank; and', 'one or more lock washer springs, said one or more lock washer springs cause said one or more lock washers to be engaged with said shank; and, 'a Jaw assembly on said shank consisting ofa Jaw assembly spring for biasing said Jaw assembly in a direction on said shank;wherein said jaw assembly holds a fastener ...

Improved connection techniques are provided. In some embodiments, specialized connectors are provided with both physical fastening and signal-conducting attributes. In some such embodiments, signals related to conditions of a connector are passed through the connector. In other embodiments, multiple-section connectors are included, which may be self-actuating and create remotely-detectable conditions and signals. 1. A connector driving system comprising a sensor and a control system , wherein said control system performs operations to:control driving power based on said sensor sensing change in seating or another condition of a connector; andapply remedial actions;wherein said remedial actions are executed if said change in seating or another condition of a connector is sensed.2. The connector driving system of claim 1 , wherein:the remedial actions comprise reducing or reverse-pulsing power when a substantial decrease in required power to turn a connector is sensed while the system is operating in a connector-tightening direction.3. The connector driving system of claim 1 , wherein:the remedial actions comprise reducing or reverse-pulsing power when a substantial increase in driver tip speed is sensed while the system is operating in a connector-tightening direction.4. The connector driving system of claim 1 , wherein a plurality of sections of a connector head driven by the system are each separately electrifiable or magnetizable and drivable by the driver tip.5. The connector driving system of claim 1 , in which tightness or failure of a physical connection may be determined based on the relative orientation of at least two sections of a multi-sectioned connector.6. The connector driving system of claim 5 , wherein the tightness of the multi-sectioned connector with a connected material is readable at least in part by a remote sensor claim 5 , external to the multi-sectioned connector claim 5 , configured to sense a decreased claim 5 , or at-risk of decreasing ...
