Abstract

A lug nut wrench has a half inch driver for receiving a lug nut socket. The driver is connected to one end of a five inch length of half-inch pipe. The other end of the pipe is welded to a one by two by three-eighths inch plate at a position near one end of the plate. One-half inch studs project from an opposite side of the plate. A solid leverage bar has a sharpened end for lifting off hub caps. Radially mounted on the bar, are holes, nuts or rings which fit over the studs. The 18 inch rod is used to increase leverage. Leverage and torque are varied by extending the bar from either the short or long end of the plate.

Claims

1. Lug nut wrench apparatus having a plate approximately eight inches by one inch by one-sixteenth inch, a pipe approximately five inches in length fixed at one end in perpendicular arrangement to the plate at a position about two inches from a longitudinal end of the plate and six inches from a second longitudinal end of the plate, first and second studs extending from the plate on a second side thereof opposite a first side from which the pipe is extended, the first and second studs being positioned near first and second longitudinal ends of the plate, the pipe terminating outwardly opposite the plate in a driving means for driving a lug nut receiving socket, a leverage bar about 18 inches in length and having a first proximal end tapered to an edge for removing a hub cap cover and having a second distal end and handle means at the second distal end and having a first stud receiving opening near the first proximal end for receiving the first stud and having a second stud receiving opening spaced along the leverage bar from the first opening toward the handle and positioned for receiving the second stud whereby the leverage bar may be connected to the leverage plate with the openings in the leverage bar receiving the studs mounted on the plate for turning the plate, the pipe and a lug nut receiving socket attached to the pipe in a tightening direction when a first side of the leverage bar is adjacent the second side of the plate with first opening receiving the first stud and the second opening receiving the second stud and whereby the leverage bar, plate, pipe and lug nut receiving socket attached to the pipe may be turned in a lug nut loosening direction when a second side of the leverage bar is adjacent the second side of the plate with the second opening near the end of the leverage bar receiving the first stud and the first opening of the leverage bar receiving the second study, whereby in the second loosening position of the leverage bar, the handle is positioned at a greater distance from the pipe than when the leverage bar is in the first tightening position.

2. The apparatus of claim 1 wherein the leverage bar is a flat bar, and wherein the first and second faces of the leverage bar are flat faces, and wherein the first and second openings extend through the leverage bar.

3. The apparatus of claim 2 wherein the first and second openings are round openings centered in the leverage bar.

4. The apparatus of claim 2 wherein the first and second openings extend from near a center of the bar and open oppositely into upper and lower edges of the bar.

5. The apparatus of claim 3 wherein the first and second openings comprise rings welded externally on edges of the bar.

6. The apparatus of claim 5 wherein the first and second rings are mounted respectively on opposite upper and lower edges of the bar.

7. The apparatus of claim 6 wherein the studs extend through the plate and in a direction from the plate parallel to the pipe whereby the first opening may be placed on the extended first stud with an edge portion of the bar bearing on the pipe to turn the plate, pipe and lug receiving socket attached to the pipe in a loosening direction, and whereby the first opening may be placed on the second extended stud with an edge of the bar resting on the pipe to turn the plate, pipe and lug receiving socket in a tightening direction.

8. A lug not wrench apparatus comprising:

a plate having first and second sides and first and second longitudinal ends and being longer than wider and wider than thick;

a pipe having first and second ends, the first end being fixed in perpendicular arrangement to the first side of the plate at a position closer to the first longitudinal end of the plate and further having a driving means for driving a lug nut receiving socket at the second end of the pipe;

first and second studs which extend from the second side of the plate, the first and second studs being positioned near the first and second longitudinal end, wherein the first stud is positioned near the first longitudinal end and is larger in diameter than the second stud;

a torque bar having first and second flattened ends and three stud receiving openings, the first flattened end being shaped to be a lifting edge for removing a hubcap cover and the second flattened edge having the first stud receiving opening for receiving the second stud, the second and third stud receiving openings are centrally positioned on the torque bar, wherein the second stud receiving opening is nearest the second flattened end of the torque bar and receives the second stud, and the third stud receiving opening is nearest the first flattened end and receives the first stud;

whereby the torque bar, plate, pipe and lug nut receiving socket attached to the pipe may be turned in a lug nut loosening direction by first placing the first stud receiving opening over the second stud and turning the torque bar in a lug nut loosening direction to initially loosen the lug nut, the lug nut is further loosened by removing the torque bar from its first placement and placing the second and third receiving openings over the second stud and first stud, respectively, and turning the lug nut in a loosening direction.

9. The apparatus of claim 8 wherein the leverage bar is a flat bar and wherein the first and second faces of the leverage bar are flat faces and wherein first and second openings extend into the leverage bar.

10. The apparatus of claim 9 wherein the first and second openings are round openings centered in the leverage bar.

11. The apparatus of claim 9 wherein the first and second openings extend from near a center of the bar and open oppositely into upper and lower edges of the bar.

12. The apparatus of claim 8 wherein the leverage bar is a round hollow bar and wherein first and second openings extend into the leverage bar and the third opening extends through the leverage bar.
