  • Publication number: 20250389158
    Abstract: Improvements in a ladder securing device for a tree, or a pole to safely secure a ladder to a tree or pole from the ground before a user ascends the ladder. The securing device is loosely fastened around the tree or pole and then lifted with the ladder to the highest position. This ensures that all the ladder raising, and rope or strap positioning is performed from the ground level. An additional tightening feature may be placed at or near the top of the ladder or at one or more positions of the ladder so the user can make any additional adjustments as they ascend, and the position of a tree may change based upon the load of the ladder on the tree. The user releases rope cord or strap from the ground after they are no longer on the ladder.

  • Patent number: 9498878
    Abstract: Improvements in an insulated high voltage extension for a socket wrench is disclosed. The extension provides electrical isolation between an operator located at one end of the insulated extension and a nut or bolt located at the other end of the insulated extension. Due to the potential for high voltage electricity to jump between conductive elements the insulated high voltage extension provides electrical isolation to reduce or prevent electrocution of an installer when the installer is working with high voltage power transmission lines. The extension can have a universal joint option that allows an operator to be slightly out-of-alignment with the nut or bolt. The extension can have a sacrificial torque limiter to prevent an installer from continuing to tighten or loosen a nut or bolt beyond a limit that can cause damage to the extension.

  • Patent number: 7607849
    Abstract: An improvement to a writing instrument with stylus, a pocket clip and an integrated letter-opening blade. The improvement consists of locating the letter-opening blade in the pocket clip of the pen. The blade is prevented from cutting the pocket of the user due to a blade protector that is mechanically linked to the mechanism that extends and retracts with the marking or writing tip. In an alternate embodiment, the blade is located on the opposite side of the pocket clip. The extending and retracting mechanism can be a variety of types including twists press, sliding. The stylus provides input to a PDA, touch screen or other tactile input device. Another embodiment includes a letter opener with a stylus.
