Patent ID: 7000865

Claim:
A snap-on ball tensioning device for attachment to a right-angle post comprising: a ball tension portion having a yarn traversing chamber extending therethrough with an entry port at one end and an exit port at the other end, one of said ports being lower than the other, an annular ball seat in said lower port, and a yarn tensioning ball seated on said ball seat to apply a tensioning force to a yarn traveling through said chamber, said ball tension portion having a first post engaging surface for positioning against the inner surface of one leg of the right-angle post; a connecting portion formed integral with said ball tension portion and projecting from said first post engaging surface; a leg portion formed integral with said connecting portion extending from said connecting portion and having a second post engaging surface for positioning against the outer surface of said one leg of said post and extending generally parallel with said first post engaging surface at a spacing at an outer end less than the thickness of the one leg of the post; said portions being sufficiently resilient to allow flexing of said leg portion away from said first post engaging surface to permit snapping of said device onto the one leg of a post with said ball tension portion at the inner surface of the one leg of the post; said leg portion has an outer end formed with a retaining lip projecting toward said second post engaging surface at an outward spacing therefrom for engaging the outer surface of the other leg of the post to retain said ball tensioning portion on the post; and an inner retaining rib projecting from one of said post engaging surfaces toward the other post engaging surface and spaced from said retaining lip a distance sufficient to position the one leg of the post therebetween.
