THREADER AND RETHREADING TOOL

Abstract

An elongated threading and rethreading tool (1) having a proximal section (2) for spinning the tool, a cylindrical distal section (3) having a cavity (7) for holding a thread-cutting die (9) and a middle section (4) for collecting debris generated during a threading process. The middle section may have at least one aperture (11) through a circumference for allowing debris to be dispersed from the tool. The distal section may have at least one aperture (6) through the circumference for inserting a set screw (10) to secure the die in the tool.

Claims

1. A threading tool comprising: an elongated rigid tool having three sections, a proximal section, a middle section and a distal section; said proximal section capable of being secured in a device for rotating the tool; said distal section being cylindrically-shaped having an outer circumference and an inner circumference forming a cavity for inserting a thread-cutting die; and said middle section having an internal to the cavity in the distal section for holding debris generated during a threading process.

2. The threading tool of claim 1 wherein the middle section further comprises: at least one aperture from the internal cavity through an outer surface of the middle section to allow debris generated during a threading process to be dispersed from the tool.

3. The threading tool of claim 1 further comprising at least one aperture in the distal section for inserting a set screw to secure the thread-cutting die in the cavity

4. The threading tool of claim 1 wherein the device for rotating the tool is a hand drill.

5. The threading tool of claim 1 wherein the device for rotating the tool is a wrench.

[0016] FIG. 5 is a perspective view of the threading and rethreading tool of the present invention having a debris-disposing aperture; and

[0017] FIG. 6 is a perspective view of the threading and rethreading tool of the present invention having a debris-disposing aperture.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] For purposes of describing the preferred embodiment, the terminology used in reference to the numbered accessories in the drawings is as follows: [0019] 1. threading tool, generally [0020] 2. proximal section [0021] 3. distal section [0022] 4. middle section [0023] 5. inner circumference of die holding cavity [0024] 6. set screw aperture [0025] 7. threading die holding cavity [0026] 8. debris holding cavity [0027] 9. thread cutting die [0028] 10. set screws [0029] 11. debris apertures

[0030] Discussing the preferred embodiments of the threading/rethreading tool of the present invention, reference is made to the drawings. FIGS. 1, 2 and 3 illustrate the threading/rethreading tool 1 in perspective, plan and end views, respectively. The tool 1 has three sections, a proximal section 2, a distal section 3 and a middle section 4. The distal section 3 has a cavity 7 having an inner circumference 5 for inserting and holding a thread cutting die 9 as illustrated in FIG. 3. The distal section 3 may have apertures 6 for inserting set screws 10 which can be rotatably tightened to securely hold the thread cutting die 9 in the tool during a threading/rethreading cutting. The middle section 4 contains an internal cavity 8 which is connected to the cavity 7 in the distal section 3, the purpose of which is to collect debris and hold generated during a threading/rethreading process. The proximal section 2 of the tool 1 as further illustrated in the end view of FIG. 4 may be circular, hexagonal or otherwise shaped to be inserting in a rotating or spinning device such as a handheld drill or socket wrench to perform the threading/rethreading process.

[0031] FIGS. 5 and 6 illustrate the threading/rethreading tool 1 described above further having at least one debris dispensing aperture 11 in the middle section 4 which allows excess debris and shavings generated during a threading/rethreading process to be dispersed from the tool 1. The threading/rethreading tool of the present invention may be made of rigid material, including without limitation metal or plastic.

[0032] It is to be understood that while a preferred embodiment of the invention is described, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and/or drawings.
