Abstract
An apparatus in a form of a tool are disclosed to pre-form bezel wire, which is used for gem stone settings or the like. The tool utilized herein is comprised of a metal block through which is formed an opening for drawing a soft metal wire against a cutting tool positioned orthogonally to the opening. The opening is characterized by larger openings at entrance and exit locations of the opening for ease in fabricating the groove. Collar means are also provided to adapt the opening to different gauge wires.

An apparatus for forming a groove in a length of jewelry metal, said apparatus comprising:
- a. an elongated body having at least upper, lower and end surfaces;
- b. at least one vertical first opening through said body between said upper and lower surfaces and perpendicular to an axis extending through said body along its largest dimension;
- c. said first opening having a larger cross-sectional opening at said upper surface than at a location whereat said axis extends through said body;
- d. a second opening extending into said body and substantially perpendicular to said first opening;
- e. a metal grooving tool positioned in said body such that it is secured within and extending through said second opening wherein the groove cutting portion of said tool extends into said first opening a desired distance to intersect the movement of jewelry metal through said first opening and for removing a track of jewelry metal and forming a desired depth groove in said length of jewelry metal as it progresses through said vertical first opening.
An apparatus for forming a groove in a metallic article, said apparatus comprising:
- a body portion having upper, lower and end surfaces;
- a vertical opening extending between said upper and lower surfaces, said vertical opening having a larger diameter at the upper end thereof than at the middle portion thereof;
- a second opening perpendicular to and in communication with said vertical opening;
- and
- a metal grooving tool positioned in said body portion within said opening and extending into said vertical opening wherein the grooving tool extends a desired distance to intersect the movement of metal through said vertical opening and for continuously removing a portion of metal and forming a continous groove in said metallic article.
