  • Stagger stick
    Patent number: 12023966
    Abstract: Generally, a device to measure the circumference of circular objects. Specifically, a device including a pair of slidingly engaged members disposed between a pair of arms configured to be engaged with tread on a tire at about the midline of a wheel, an electrical circuit which varies in output voltage based on the distance between the pair of arms, and a processor communicatively coupled to a non-transitory computer readable medium containing a program which correlates the output voltage of the electrical circuit to a unit measure of distance between the pair of arms and calculates tire circumference.
    Type: Grant
    Filed: June 30, 2022
    Date of Patent: July 2, 2024
    Assignee: Wehrs Machine & Racing Products, Inc.
    Inventors: Chad Larry Wehrs, Dan Fredrickson
