Abstract

A novel head device generally consisting of at least one aperture that is capable of excepting different sizes of safety wire, at least one cam-locking lever, which may incorporate a spring return mechanism, is disclosed. The body may be rotated by a mechanical means which twists the safety wire. In preferred embodiment, the various elements of the safety wire twister device are each configured with means of limiting torque or twists of safety wire to eliminate possibility of over torqueing or twisting of safety wire.

Claims

1. A method of manufacturing a safety wire twisting system, comprising:

attaching a fastening body to a shaft;

configuring the fastening body to be rotatable about the axis of the shaft;

configuring the fastening body to in incorporate at least one aperture acting as an insertion point for safety wire to be inserted;

positioning at least one cam-locking lever within the fastening body;

configuring first and second slots on either side of the cam-locking lever; and

attaching a torque provider to the fastening body to provide rotation.

2. The method of claim 1, further comprising:

the torque provider acting as a mechanical means of rotation of the shaft.

3. The method of claim 2, further comprising:

positioning a slip clutch within the fastening head; and

the slip clutch acting as a torque limiter that automatically slips or disengages a clutch-fitting once a predetermined threshold of torque is achieved.

4. The method of claim 1, further comprising:

configuring the fastener body to accept one or more free ends of the safety wire.

5. The method of claim 4, further comprising:

the fastener body incorporating one or more apertures which can be locked to accept and secure the one or more free ends of the safety wire.

6. The method of claim 1, further comprising:

a pivoting head allowing use in horizontal or pistol grip configuration of the fastening body.

7. The method of claim 1, further comprising:

locating a quick disconnect collet on the shaft for accepting a predetermined shape coupling of the shaft body.

8. The method of claim 3, further comprising:

configuring the slip clutch to be user-adjustable thereby obtaining a predetermined threshold number of twists per inch of the safety wire.

9. The method of claim 5, further comprising:

locating the one or more apertures in a small diameter end of the fastener body; and

the one or more aperture(s) accepting the one or more free ends of the safety wire.

10. The method of claim 1, further comprising:

incorporating one or more cam-locking levers within the fastening body thereby insuring that the safety wire remains secured within the fastener body during use.

11. The method of claim 1, further comprising:

the shaft being hexagonal.

12. The method of claim 1, further comprising:

determining a desired threshold of resistance to torque from the safety wire through the fastening body; and

configuring and adjusting the compression nut and lock nut to match with the desired threshold of resistance.

13. The method of claim 1, further comprising:

attaching the fastening body to the shaft; and

attaching the shaft to the clutch plate.

14. The method of claim 13, further comprising:

directly attaching the drive plate to a shaft of the torque provider;

wherein the clutch plate selectively engages and disengages with the drive plate.

15. The method of claim 13, further comprising:

wherein when the system is at rest and not in use, the clutch plate being mechanically attached to and moving in mechanical unison with the drive plate.

16. The method of claim 15, further comprising:

affixing the clutch plate to the shaft such that the shaft drives (rotates) the fastening body such that when the clutch plate is engaged with the drive plate, and the torque provider is activated, the fastening body rotates.

17. The method of claim 10, further comprising:

the cam-locking levers incorporating a spring mechanism to return the cam-locking levers back to an engaged position.

18. The method of claim 10, further comprising:

manufacturing the cam-locking levers with an aperture therein for allowing the lever to pivot around a pin affixed to the fastening body.

19. The method of claim 10, further comprising:

one or more top ends of the cam-locking levers are specially positioned to be finger-accessible and thus accessible for being pushed forward.

20. The method of claim 1, further comprising:

the shaft further comprising a groove suitable for securing the shaft into a quick-disconnect collet.
