DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) An embodiment 2 of the inventive tool for manually driving and extracting a T-post 5 is shown in FIGS. 1-5. The inventive tool 2 preferably comprises: (a) a tube 4 having a longitudinal axis 6; (b) an open extraction slot 8 which is formed in the wall 10 of the tube 4; and (c) a pair of handles 12 and 14 which are secured, e.g., by welding or in any other suitable manner, on opposite sides of the tube 4.

(7) The tube 4 comprises a first longitudinal end 16 which is open and a second longitudinal end 18 which is closed. The tube wall 10 extends from the first longitudinal end 16 to the second longitudinal end 18.

(8) When the inventive tool 2 is used for driving the T-post 5 into the ground, the first longitudinal end 16 of the tube 4 will become a lower end of the tool 2, in which the upper end of the T-post 5 will be received, and the second longitudinal end 18 of the tool 2 will be used to contact and drive/hammer the T-post 5 into the ground. However, when the inventive tool 2 is used to extract the T-post 5 from the ground, the first longitudinal end 16 of the tube 4 will become the upper end of the tool 2.

(9) The open extraction slot 8 formed in the tube wall 10 has a lateral opening 22 at the first longitudinal end 16 of the tube 4. The open extraction slot 8 extends from the first open longitudinal end 16 of the tube 4 toward the second longitudinal end 18. The longitudinal length of the open extraction slot 8 is preferably not more than half, more preferably less than half, of the total longitudinal length of the tube 4.

(10) The longitudinal length of the tube 4 will preferably be in the range of from about 20 inches to about 36 inches and will more preferably be from about 24 to about 34 inches. As used herein and in the claims, the term about, when used in reference to a dimensional size or arc, encompasses a range of 10%.

(11) The cross-sectional shape of the tube 4 can be circular, square, rectangular, or any other shape desired. The tube 4 will preferably be cylindrical and will more preferably be formed of a segment of pipe. For a cylindrical tube 4 having a circular cross-sectional shape, the internal diameter of the tube 4 will preferably be in the range of from about 2 inches to about 5 inches and will more preferably be in the range of from about 2.5 inches to about 4 inches. The internal diameter of the tube 4 will more preferably be about 3 inches.

(12) The tube 4 will preferably be formed of metal, more preferably steel, and will most preferably be formed of a segment of 3 inch pipe.

(13) The open extraction slot 8 and the lateral opening 22 thereof are of sufficient lateral width that when the inventive tool 2 is positioned with the closed longitudinal end 18 of the tube 4 oriented downward (i.e., with the closed end of the tool 2 supported on a ground surface) and the first longitudinal end 16 of the tube 4 is tilted toward the T-post 5, the T-post 5 will be received in the open extraction slot 8 such that a portion 24 of the upper edge 26 of the tube wall 10 at the first longitudinal end 16 of the tube 4 will contact the T-post 5 between an adjacent pair 28a and 28b of the stubs which project from the T-post 5. The portion 24 of the upper edge 26 (i.e., the back edge) of the tube wall 10 which is received between the projecting stubs 28a and 28b is positioned opposite the lateral opening 22 of the open extraction slot 20.

(14) For a cylindrical tube 4, the edge 26 of the tube wall 10 at the first open longitudinal end 16 will preferably have a C-shape.

(15) The longitudinal length of the open extraction slot 8 will preferably be in the range of from about 3 to about 12 inches. The longitudinal length of the open extraction slot 8 will more preferably be in the range of from about 5 to about 11 inches and will more preferably be in the range of from about 8 to about 10 inches. The other longitudinal end 30 of the open extraction slot 8, which is opposite the lateral opening 22 of the slot 8, will preferably curve toward the second longitudinal end 18 of the tube 4. The open extraction slot 8 and the lateral opening 22 thereof will preferably have a width which is in the range of from about 1.5 inches to about 2.5 inches and is more preferably about 2 inches.

(16) The handles 12 and 14 of the inventive tool 2 are welded or otherwise attached to the tube 4 so that the handles 12 and 14 do not obstruct the open extraction slot 8. The handles 12 and 14 are preferably positioned (i) about 180 from each other and (ii) about 90 from a longitudinally extending center line 32 of the open extraction slot 8 which is parallel to the longitudinal axis 6 of the tube 4.

(17) The inventive tool 2 can also comprise an extraction adjustment handle 34 which is welded or otherwise attached to the tube 4 at a location which is preferably (i) adjacent to the first longitudinal end 16 of the tube 4 and (ii) opposite the open extraction slot 8. The handle 34 can be used to position or reposition the portion 24 of the first longitudinal end 16 of the tube 4 between any desired pair of the projecting stubs 28a and 28b of the T-post 5 at a desired height.

(18) In addition, the inventive tool 2 can further comprise a slip-resistant surface 36 on the exterior of the tube wall 10 which is preferably located (i) adjacent to the second longitudinal end 18 of the tube 4 and (ii) on the lateral side of the tube 4 which is opposite the lateral side of the open extraction slot 8. When extracting a T-post 5 from the ground, the user can place a foot on the slip resistant surface 36 for greater leverage when pushing or pulling the T-post 5 toward or away from the inventive tool 2. By way of example, but not by way of limitation, the slip resistant surface 36 can compromise boot grooves formed in the exterior of the tube 4 or a strip of sticky sandpaper or other slip resistant material.

(19) In the method of the present invention for extracting the lower end portion of a T-post 5 from the ground, the closed end of the inventive driving and extraction tool 2 is placed on the ground surface adjacent to the T-post 5. Either before, after, or while placing the closed end of the tool 2 on the ground, the T-post 5 is received in the open extraction slot 8 of the tool 2 (e.g., by tilting the first upper end 16 of the tube 4 toward the T-post 5) such that the portion 24 of the first upper end 16 of the tube wall 10 contacts the T-post 5 between an adjacent pair 28a and 28b of the projecting stubs of the T-post 5. The user then pulls or pushes the upper portion of the T-post 5 in a direction toward the tool 2 such that the portion 24 of the first upper end 16 of the tool 2 catches the upper stub 28a of the pair of projecting stubs 28a and 28b, which results in the T-post 5 being pulled upwardly.

(20) Next, the user pulls or pushes the upper portion of the T-post 5 away from the tool 2 so that the portion 24 of the first upper end 16 of the tool 2 falls (ratchets) downwardly to a position between a lower adjacent pair 28b and 28c of the projecting stubs.

(21) The steps of pulling or pushing the upper portion of the T-post 5 toward and then away from the inventive tool 2 are then repeated until the T-post 5 is free from the ground or is at least sufficiently free to allow the T-post 5 to be lifted out of the ground by hand.
