  • Publication number: 20230083569
    Abstract: A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

  • Publication number: 20170064937
    Abstract: A fishing device, for use with a reel and rod combination having fishing line with attached terminal tackle, includes a base, an indicator device, a trigger mechanism, and a line device. The base has a hole and slot configuration to allow a fishing line to feed through the base. The indicator device is coupled to the base and is configured to indicate the presence of a fish. The trigger mechanism is configured to cause the indicator device to pop up when the trigger device is activated. The line device attaches to the fishing line and is configured to activate the trigger mechanism. When a fish pulls on the terminal tackle, the line device activates the trigger mechanism that causes the indicator device to pop-up indicating to a user the presence of a fish.

  • Patent number: 9347774
    Abstract: An improvement in workpiece-engageable devices for accurate workpiece angular formation including a plurality of spirit vials and an engager of a workpiece which establishes an intended bending plane. The plurality of spirit vials includes formation-angle vials adjacent to one another and supported in a respective plane parallel to the intended bending plane and in an orientation corresponding to a respective one of intended angles with respect to a base plane. At least one control vial is supported in a body of the device and aligned in a plane parallel to the base plane. The formation-angle vials may include four formation-angle vials each oriented at one of angles 10°, 22.5°, 30°, 45°, 90° and in some embodiments 60° with respect to the base plane.
