Firing pin actuation and reset mechanism for a powder actuated setting tool and method
Disclosed herein is a method that relates to resetting and firing a powder actuated setting tool. The method includes resetting the tool by torsionally urging a portion of a firing pin into axial alignment with a finger of a barrel of the tool and compressing the barrel of the tool toward a housing of the tool. The resetting further includes the finger urging the portion of the firing pin to a ready position in response to the compression of the barrel. The method further includes firing the tool by rotating a rotator and the firing pin to a position where the portion of the firing pin is unsupported by the finger.
1. A method for resetting and firing a powder actuated setting tool comprising:
torsionally urging a portion of a firing pin into axial alignment with a finger of a barrel of the tool;
compressing the barrel of the tool toward a housing of the tool, the finger urging the portion of the firing pin to a ready position; and
rotating a rotator and the firing pin to a position where the portion of the firing pin is unsupported by the finger.
2. The method for resetting and firing a powder actuated setting tool of claim 1 wherein a spiral torsion spring provides the torsional urging.
3. The method for resetting and firing a powder actuated setting tool of claim 1 wherein the rotating of the rotator is against the torsional urging.
4. The method for resetting and firing a powder actuated setting tool of claim 1 wherein the torsional urging automatically reverses the rotation of the rotator and the firing pin.
