Patents by Inventor Rollin Woodruff

Rollin Woodruff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7862008
    Abstract: A winch has a color area or other indicium that indicates whether an elongate member extending from winch spool is or is not tensioned. The winch includes a biasing member between a winch drive system and the spool that allows only limited rotation of the spool relative to the drive system. Movement of the drive system relative to the winch spool causes the indicium to signal that the elongate member is under tension.
    Type: Grant

  • Publication number: 20060133905
    Abstract: A manually operated winch system secures cargo to a transport vehicle. The winch system has a shaft rotationally mounted relative a frame. A ratchet drive mechanism controls rotation of the shaft. A handle received in the drive mechanism can be used both to control rotation of the shaft and to control operation of a pawl. The drive mechanism is configured such that tilting the handle moves a member axially. Sufficient axial movement of the member causes the pawl to disengage mating ratchet teeth and thereby allows the shaft to rotate freely.

  • Patent number: 6558092
    Abstract: A manually operated winch system secures cargo to a transport vehicle. The winch system has a shaft rotationally mounted relative a frame. A ratchet drive mechanism controls rotation of the shaft. A handle received in the drive mechanism can be used both to control rotation of the shaft and to control operation of a pawl. The drive mechanism is configured such that tilting the handle moves a member axially. Sufficient axial movement of the member causes the pawl to disengage mating ratchet teeth and thereby allows the shaft to rotate freely. In some embodiments, an adjustment mechanism limits the extent to which the member can move axially.
