Abstract

Claims (34)

1. A coupler, comprising:

a) a single body having a first end and a second end;

b) the single body including a first hole extending from the first end and a second hole extending from the second end, the first hole including a side wall, the first hole for receiving an end portion of a first rod and the second hole for receiving an end portion of a second rod;

c) the single body including a longitudinal first cutout extending into the side wall to expose the end portion of the first rod to be welded to the single body, the single body being single before the first rod to be welded is inserted into the first hole; and

d) the first cutout including a longitudinal first side wall surface and a longitudinal second side wall surface, the first side wall surface being transverse to the second side wall surface.

2. The coupler as in claim 1 , wherein the first side wall surface includes a guide for a thickness of a welding bead to be deposited on the single body.

3. The coupler as in claim 2 , wherein the guide includes a shoulder disposed longitudinally on the first side wall surface.

4. The coupler as in claim 2 , wherein the guide includes a plurality of recesses disposed in the first side wall surface.

5. The coupler as in claim 4 , wherein the recesses are disposed radially in the first side wall surface.

6. The coupler as in claim 2 , wherein the guide comprises a straight line disposed on the first side wall surface at a radial distance from the first hole.

7. The coupler as in claim 6 , wherein the straight line comprises a scored straight line on the first side wall surface.

8. The coupler as in claim 6 , wherein the straight line comprises a shoulder on the first side wall surface.

9. The coupler as in claim 1 , wherein the first side wall surface is perpendicular to the second side wall surface.

10. The coupler as in claim 1 , wherein:

a) the first cutout extends into the first end; and

b) the first cutout is U-shaped.

11. The coupler as in claim 1 , wherein the second hole communicates with the first hole and a sight hole is disposed at a junction of the first hole and the second hole.

12. The coupler as in claim 1 , wherein the second hole includes multiple diameters.

13. The coupler as in claim 1 , wherein the single body includes a second longitudinal cutout extending into the side wall to expose the end portion of the first rod to be welded to the single body.

14. The coupler as in claim 13 , wherein the first cutout is opposite the second cutout.

15. The coupler as in claim 1 , wherein the second hole is threaded.

16. The coupler as in claim 1 , wherein the second end includes a third hole.

17. The coupler as in claim 1 , wherein the second hole is off-center from the first hole.

18. The coupler as in claim 1 , wherein the first hole is coaxial with the second hole.

19. The coupler as in claim 1 , wherein the second hole is axially disposed into the side wall.

20. The coupler as in claim 1 , wherein:

a) the first hole and the second hole are coaxial; and

b) the first cutout is configured for exposing the end portion of the second rod to be welded to the single body.

21. The coupler as in claim 1 , wherein:

a) the second hole is coaxial with the first hole, the second hole including a second side wall; and

b) the single body includes a longitudinal second cutout extending into the second side wall for exposing the end portion of the second rod to be welded to the single body.

22. The coupler as in claim 1 , wherein the first hole extends past the first cutout.

23. The coupler as in claim 1 , wherein the first hole is larger in diameter than the second hole.

24. The coupler as in claim 1 , wherein the single body includes a cylindrical body.
