Abstract
A method of making a lifting grommet provides a connector body that is specially configured. The body has opposed end portions and a centrally positioned open area or gap. Each end portion of the body has a bore. A length of wire is provided having a pair of rope end portions. As part of the method, a bore and a centrally positioned opening or gap is engaged with a wire rope end portion. Once an end portion extends to the bore or gap, it is frayed, spread apart or unraveled. As part of the method, each portion of the wire rope is enveloped with a mass of adhesive filler material such as epoxy.
Claims25
A method of making an endless loop lifting grommet, comprising the steps of:
- a) providing a body having opposed body end portions and a centrally positioned open area;
- b) each shaped end portion having a bore with first and second cylindrically shaped sections wherein the first section is of a larger diameter than the second section;
- c) providing a length of wire rope of metallic material having first and second wire rope end portions, each said wire rope end portion having an outer diameter, said wire rope being comprised of a plurality of individual wires;
- d) engaging a first said bore with the first wire rope end portion;
- e) engaging a second said bore with the second wire rope end portion;
- f) connecting the wire rope end portions to the body to form an endless loop grommet by adding a filler to the first section of each of the bores via the centrally positioned opening to envelope said rope end portions with a mass of adhesive filler material;
- g) wherein in step “f” neither wire rope end portion forms a knot and the said bores each provide a larger diameter section, each larger diameter section having an internal diameter that is larger than the outer diameter of the wire rope end portion that occupies the said bore;
- h) wherein in steps “d” through “g” the wire rope end portions are spaced apart with the body centrally positioned open area in between the rope end portions.
A lifting grommet, comprising:
- a) a body having opposed end portions and a centrally positioned open area;
- b) each end portion having a bore, wherein the said bores each provide a larger diameter section that is next to the open area and a smaller diameter cylindrically shaped section spaced away from the open area;
- c) a length of wire rope having first and second rope end portions, each wire rope end portion having an outer diameter and engaging said bore and extending to a position next to the centrally positioned opening so that a filler material can be added to the larger diameter sections via the centrally positioned opening, each larger diameter section having an internal diameter that is larger than the outer diameter of the rope end portion that occupies the said bore;
- d) the wire rope end portions being individual wires that are spread apart, each extending end portion to the centrally positioned opening wherein the said rope end portions extend to the opening;
- e) a mass of adhesive filler material that occupies the larger diameter sections of the bores, enveloping each of said rope end portions;
- f) wherein neither said wire rope end portion forms a knot;
- g) wherein the wire rope and body form an endless loop;
- h) wherein the wire rope end portions are spaced apart with the body centrally positioned open area in between the rope end portions.
