  • Patent number: 4300412
    Abstract: A support apparatus for removing lugs from a vehicle wheel comprises a U shaped base member having a central rod rotatably coupled between the upstanding arms of the U via coaxial apertures in each arm. A T shaped section is located between the upstanding arms and is rigidly secured to the rod. A large lever arm is selectively inserted into the T shaped section to enable a user to develop a large torque while resting his foot and hence, applying his full body weight to the base of the U shaped member which is resting upon the ground when a force is exerted upon the upstanding lever arm. Once the lug is turned, the lever arm may be removed and the user has access to the rotatable rod to further rotate the lug so that it may be completely removed from the wheel.
