Abstract

A device comprising: (a) a first working arm; (b) a shuttle located on the first working arm, and (c) a bias device; wherein the bias device biases the first working arm when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm when the shuttle is in a second position.

First claim

We claim:

1. A device comprising:
a first working arm;
a second working arm;
a first shuttle located on the first working arm;
a second shuttle located on the second working arm; and
a bias device;
wherein the bias device contacts the second shuttle when the first shuttle is in a first position,
wherein the bias device biases the first working arm when the first shuttle is in the first position, and
wherein the bias device is free of biasing the first working arm when the first shuttle is in a second position.

2. The device of claim 1 , wherein the bias device is located on the first shuttle.

3. The device of claim 1 , wherein the bias device is free of contact with the second shuttle when the first shuttle is in the second position.

4. The device of claim 1 , wherein the second shuttle on the second working arm is movable relative to the first shuttle on the first working arm.

5. The device of claim 1 , wherein in the first position the first shuttle and the second shuttle are aligned.

6. The device of claim 5 , wherein in the second position the first shuttle and the second shuttle are misaligned.

7. The device of claim 1 , wherein the bias device comprises a spring.

8. The device of claim 1 , wherein the bias device includes a constrained end coupled to the first shuttle and a free end that is configured to contact the second shuttle.

9. The device of claim 1 , wherein the first shuttle and the second shuttle are longitudinally slidable relative to each other.

10. A device comprising:
a first working arm;
a second working arm;
a shuttle located on the first working arm;
a bias device located on the shuttle; and
a deactivation feature located on the second working arm;
wherein the bias device biases the first working arm away from the second working arm when the shuttle is misaligned with the deactivation feature, and wherein the bias device is free of biasing the first working arm when the shuttle is aligned with the deactivation feature.

11. The device of claim 10 , wherein the deactivation feature comprises a recess in the second working arm.

12. The device of claim 10 , wherein the bias device comprises a spring.

13. The device of claim 10 , wherein the bias device includes a constrained end coupled to the shuttle and a free end that contacts the second working arm when the shuttle is misaligned with the deactivation feature.

14. A device comprising:
a first working arm;
a second working arm;
a first shuttle located on the first working arm;
a bias device located on the first shuttle; and
a second shuttle located on the second working arm;
wherein the bias device biases the first working arm when the first shuttle is aligned with the second shuttle, and wherein the bias device is free of biasing the first working arm when the first shuttle is misaligned with the second shuttle.

15. The device of claim 14 , wherein the second shuttle on the second working arm is movable relative to the first shuttle on the first working arm.

16. The device of claim 14 , wherein the bias device contacts the second shuttle when the first shuttle is aligned with the second shuttle.

17. The device of claim 16 , wherein the bias device is free of contact with the second shuttle when the first shuttle and the second shuttle are misaligned.

18. The device of claim 14 , wherein the bias device comprises a spring.

19. The device of claim 14 , wherein the first shuttle and the second shuttle are longitudinally slidable relative to each other.
