Abstract
Apparatus and method for a T-shaped wrench having three drive stems including a base drive stem wherein the top portion of the wrench has opposing ends or drive stems which are 30 degrees offset from each other. The angularly offset drive stems of the top portion allow the wrench to be used in tight areas where other wrenches are not usable.
Claims7
A wrench comprising:
- a) a T-shaped body comprising a lower base member having a drive stem thereon and an upper straight cross member having first and second drive stems aligned along a common, straight central axis;
- b) wherein said drive stem of said lower base member, said first drive stem and said second drive stem each are in cross section a polygon with a plurality of equal sides;
- and,
- c) wherein corresponding sides of said first and said second drive stems are angularly offset from each other around said axis.
1 more element
A method for making a wrench comprising the steps of:
- a) providing a T-shaped body having a lower base member having a drive stem thereon and an upper straight cross member having first and second drive stems aligned along a straight, common central axis;
- b) wherein the drive stem of the lower base member, the first drive stem and the second drive stem each are in cross section a polygon with a plurality of equal sides;
- and,
- c) wherein corresponding sides of the first and second drive stems are angularly offset from each other around said axis.
1 more element
A method of using a wrench having a plurality of sides, comprising the steps of:
- providing a T-shaped body having a lower base member having a drive stem thereon and an upper cross member having a first and a second drive stem thereon, wherein the drive stem of the lower base member, the first drive stem and the second drive stem each have a plurality of equal sides, wherein the sides of the first and second drive stems are angularly offset from each other, wherein a user grasps the lower base member in his hand and places the first drive stem of the cross member in the drive socket of a screw, wherein the user then turns the screw a number of degrees, wherein the user removes the first drive stem from the drive socket of the screw, wherein the user rotates the lower base member to 180 degrees in his hand, wherein the user repositions the second drive stem of the cross member in the drive socket of the screw by rotating the lower base member backwardly 30 degrees in a horizontal plane, and, wherein the user places the second drive stem in the drive socket of the screw so that the user can then rotate the screw an additional 30 degrees.
