  • Patent number: 8919225
    Abstract: The adjustable socket design uses a weave of cables to position six arms which are used to torque a nut. The arms have a gripping surface to torque the nut. The design also allows for a quick and easy size adjustment. When the top of the socket is separated from the bottom, the two parts are twisted relative to each other which moves the arm positions to accommodate different nut sizes. When the top and bottom of the socket are pushed together, they fix the arm positions and the socket is used as a traditional fixed sized socket.

  • Publication number: 20140144294
    Abstract: The invention comprises a ratchet style flare nut wrench which incorporates an assembly to provide a torqueing function and ratchet effect. The assembly includes a wrench body capable of providing torque delivery through three rotating cylindrical cams which contact the nut. The cylindrical cams then rotate when reversing the direction of the wrench assembly so that a cutout portion of the cylindrical cams allows the nut points to pass by. Two cylinder cams are mounted on movable guide blocks which adjust the wrench for different size nuts.

  • Patent number: 8596168
    Abstract: The invention comprises a ratchet style open end wrench which incorporates an assembly to provide a torqueing function and ratchet effect. The assembly includes a wrench body capable of providing torque delivery through two or more rotating cylindrical cams which contact the nut. The cylindrical cams then rotate when reversing the direction of the wrench assembly so that a cutout portion of the cylindrical cams allows the nut points to pass by. In one embodiment, the direction of the ratchet effect is reversible by a reversing arc wire which is activated by use of a lever.
