Abstract

A slip and cone arrangement including a slip having a centrally located cone interconnection feature, and a cone having a slip retention feature engageable with the interconnection feature. A slip including a body, the body having a T section, and an engagement section, the engagement section having a centrally located cone interconnection feature.

First claim

What is claimed is:

1. A slip and cone arrangement comprising:
a slip having a centrally located cone interconnection feature including a bifurcation of a body of the slip and a track flange medially thereon; and
a cone having a slip retention feature engageable with the interconnection feature.

2. The arrangement as claimed in claim 1 wherein the cone interconnection feature is slidably engageable with the slip retention feature such that the slip is movable relative to the cone in selected directions and prohibited from movement relative to the cone in other directions.

3. The arrangement as claimed in claim 1 wherein the bifurcation creates two legs.

4. The arrangement as claimed in claim 1 wherein the bifurcation is dimensioned positioned and configured to slidingly receive and engage with the slip retention feature.

5. The arrangement as claimed in claim 1 wherein the slip retention feature is a finger emanating from a ramp surface of the cone.

6. The arrangement as claimed in claim 5 wherein the finger includes a track groove receptive of a track flange centrally located on the slip.

7. The arrangement as claimed in claim 5 wherein the finger includes a stop.

8. The arrangement as claimed in claim 1 wherein the slip retention feature is a recess.

9. The arrangement as claimed in claim 8 wherein the recess is a dovetail.

10. The arrangement as claimed in claim 9 wherein the dovetail includes a relatively narrower gate and a relatively wider track.

11. A slip and cone arrangement comprising:
a slip having a centrally located cone interconnection feature; and
a cone having a slip retention feature engageable with the interconnection feature, wherein the interconnection feature comprises a nose disposed at a longitudinal midline of the slip.

12. The arrangement as claimed in claim 11 wherein the nose is complementary to the slip retention feature.

13. The arrangement as claimed in claim 11 wherein the nose protrudes from the slip.

14. A slip comprising:
a body, the body having:
a T section; and
an engagement section, the engagement section having a centrally located cone interconnection feature, wherein the engagement section includes a nose configured positioned and dimensioned to interact with a recess in a cone.

15. The slip as claimed in claim 14 wherein the engagement section includes a bifurcation.
