Abstract

A nail channel for a fastening tool. The nail channel can be a unitary piece or have a variety of parts. The nail channel can have a first portion provided by a fastener magazine and a second portion provided by a nosepiece insert. The nail channel can be formed when the nosepiece insert is reversibly engaged with a nose end of a nailer magazine. The nail channel can also position a fastener, such as a nail, for driving into a workpiece. Methods of forming and using the nail channel are also disclosed.

Claims (43)

1. A fastening tool, comprising:

a fastener driving channel having a first portion reversibly engaged to a second portion, the second portion having a nosepiece insert;

wherein the fastener driving channel has an internal circumference that is substantially circular and the nosepiece insert has a nosepiece insert channel arcuate angle in the range of 3% to 95% of the arcuate angle of the internal circumference.

2. The fastening tool according to claim 1 , wherein the driving channel is a nail driving channel adapted for driving a fastener.

3. The fastening tool according to claim 1 , wherein at least a portion of the nosepiece insert is investment cast.

4. The fastening tool according to claim 1 , wherein the nosepiece insert comprises aluminum.

5. The fastening tool according to claim 1 , wherein the nosepiece insert comprises steel.

6. The fastening tool according to claim 1 , wherein the fastener driving channel comprises a fastener stop.

7. The fastening tool according to claim 1 , wherein the fastener driving channel comprises a blade guide.

8. The fastening tool of claim 1 , wherein the fastener driving channel comprises a blade guide, and the fastening tool has a driving blade that partially overlaps a portion of the blade guide.

9. The fastening tool according to claim 1 , wherein the fastener driving channel comprises a nail stop having a nail stop length of 50 mm or less.

10. The fastening tool according to claim 1 , wherein the nosepiece insert comprises a nail stop.

11. The fastening tool according to claim 1 , wherein the fastener driving channel has an internal circumference that is substantially circular.

12. The fastening tool according to claim 1 , wherein about 50% of an inner circumference of the fastener driving channel is provided by the nosepiece insert and about 50% of the inner circumference of the fastener driving channel is provided by a magazine interface.

13. The fastening tool according to claim 1 , wherein the nosepiece insert channel arcuate angle is in the range of 10% to 80% of the arcuate angle of the internal circumference.

14. The fastening tool according to claim 1 , wherein the nosepiece insert channel arcuate angle is in the range of 33% to 66% of the arcuate angle of the internal circumference.

15. A method for positioning a nail head for driving, comprising the steps of:

providing a fastener driving channel wherein about 50% of an inner circumference of the fastener driving channel is provided by the nosepiece insert and about 50% of the inner circumference of the fastener driving channel is provided by a magazine interface;

said fastener driving channel having a first portion reversibly engaged to a second portion, the second portion having a portion of a nosepiece insert adapted to receive a nail and to position the nail head;

feeding the nail to the driving channel; and

positioning the nail head with a portion of the nosepiece insert.

16. A fastening tool, comprising:

a fastener driving channel having a first portion reversibly engaged to a second portion, the second portion having a nosepiece insert;

wherein about 50% of an inner circumference of the fastener driving channel is provided by the nosepiece insert and about 50% of the inner circumference of the fastener driving channel is provided by a magazine interface.

17. The fastening tool according to claim 16 , wherein the driving channel is a nail driving channel adapted for driving a fastener.

18. The fastening tool according to claim 16 , wherein at least a portion of the nosepiece insert is investment cast.

19. The fastening tool according to claim 16 , wherein the nosepiece insert comprises aluminum.

20. The fastening tool according to claim 16 , wherein the nosepiece insert comprises steel.

21. The fastening tool according to claim 16 , wherein the fastener driving channel comprises a fastener stop.

22. The fastening tool according to claim 16 , wherein the fastener driving channel comprises a blade guide.

23. The fastening tool of claim 16 , wherein the fastener driving channel comprises a blade guide, and the fastening tool has a driving blade that partially overlaps a portion of the blade guide.

24. The fastening tool according to claim 16 , wherein the fastener driving channel comprises a nail stop having a nail stop length of 50 mm or less.

25. The fastening tool according to claim 16 , wherein the nosepiece insert comprises a nail stop.

26. The fastening tool according to claim 16 , wherein the fastener driving channel has an internal circumference that is substantially circular.

27. A method for positioning a nail head for driving, comprising the steps of:

providing a fastener driving channel wherein the fastener driving channel has an internal circumference that is substantially circular and the nosepiece insert has a nosepiece insert channel arcuate angle in the range of 3% to 95% of the arcuate angle of the internal circumference;

providing said fastener driving channel has a first portion reversibly engaged to a second portion, the second portion having a portion of a nosepiece insert adapted to receive a nail and to position the nail head;

feeding the nail to the driving channel; and

positioning the nail head with a portion of the nosepiece insert.

28. The method for positioning a nail head for driving according to claim 27 , further comprising the step of:

providing the nosepiece insert channel arcuate angle in the range of 10% to 80% of the arcuate angle of the internal circumference.

29. The method for positioning a nail head for driving according to claim 27 , further comprising the step of:

providing the nosepiece insert channel arcuate angle in the range of 33% to 66% of the arcuate angle of the internal circumference.
