Abstract

A rope termination device. The device includes a cylindrical body having a first opening in a first axial end of the body. A second opening in an opposed, second end of the body is connected by a passageway through the body to the first opening. At least one circular channel is in communication with the second opening. A continuous helical groove is provided around a circumference of the cylindrical body. An attachment connector is provided near the second end of the body.

Claims (27)

1. A rope termination device which comprises:

a cylindrical body having a first opening in a first axial end of said body;

a second opening in an opposed, second end of said body connected by a passageway through said body to said first opening;

at least one circular channel in communication with said second opening;

a continuous helical groove around a circumference of said cylindrical body; and

an attachment connector near said second end of said body.

2. The rope termination device as set forth in claim 1 wherein said at least one circular channel comprises a pair of adjacent circular channels.

3. The rope termination device as set forth in claim 1 wherein said attachment connector comprises an eye having an axis perpendicular to an axis of said body.

4. The rope termination device as set forth in claim 1 wherein said attachment connector comprises a clevis extending from said at least one circular channel.

5. The rope termination device as set forth in claim 1 including a transition groove joining said at least one circular channel and said continuous helical groove.

6. The rope termination device as set forth in claim 1 wherein a rope is threaded into said body from said first opening, through said passageway, and out of said second opening of said body, threaded around said at least one circular channel and thereafter in said continuous helical groove with an end of said rope inserted beneath windings of said rope in said continuous helical groove.

7. The rope termination device as set forth in claim 1 including a post extending radially from said body and a further groove transverse to said continuous helical groove.

8. The method of terminating a rope, which method comprises:

threading a rope into a first axial opening in a cylindrical body, through a passageway through said body, and out of an opposed second end of said body;

thereafter passing said rope around at least one circular channel; and

thereafter winding said rope around a continuous helical groove around a circumference of said cylindrical body in a corkscrew pattern to form windings while inserting an end of said rope beneath said windings.

9. The method of terminating a rope as set forth in claim 8 wherein said step of passing said rope around at least one circular channel comprises passing said rope around two adjacent said circular channels in sequence.

10. The method of terminating a rope as set forth in claim 8 wherein said step of inserting an end of said rope beneath said windings includes inserting said end in a further groove transverse to said continuous helical groove.

11. The method of terminating a rope as set forth in claim 8 including providing an attachment connector near said second end of said body.

12. The method of terminating a rope as set forth in claim 11 wherein said attachment connector comprises an eye having an axis perpendicular to an axis of said body.

13. The method of terminating a rope as set forth in claim 11 wherein said attachment connector comprises a clevis extending from said at least one circular channel.

14. A rope termination device which comprises:

a cylindrical body having a first opening in a first end of said body, and a second opening in an opposed, second end of said body connected by a passageway therethrough for receipt of a rope; and

a rope self-tightening mechanism having a continuous helical groove around a circumference of said cylindrical body in a corkscrew pattern to receive said rope therein to form windings with an end of said rope beneath said windings of said rope.

15. The rope termination device as set forth in claim 14 including an attachment connector near said second end of said body.

16. The rope termination device as set forth in claim 15 wherein said attachment connector comprises an eye perpendicular to an axis of said body.

17. The rope termination device as set forth in claim 15 wherein said attachment connector comprises a clevis.
