Abstract
A jewel setting method comprising the steps of: making a hole in an elastic object; forming overhangs around the top circumference of the hole; and press-fitting a jewel into the hole by causing the overhangs to be yieldingly withdrawn, allowing the girdle of the jewel to pass through the space delimited by the surrounding overhangs, and then, allowing the overhangs to return to their original positions, thereby catching the bezel of the jewel. Examples of such materials are plastic, ivory, horn, wood and metal.
Claims9
A method of setting at least one jewel in an object which is of an elastic material comprising the steps of:
- making in the object, a hole which corresponds to the jewel in shape, but is somewhat smaller than the largest diameter of the jewel;
- making a circumferential slot on the inner wall of the hole just below the top circumference of the hole opening, the slot having a diameter larger than the largest diameter of the jewel;
- and press-fitting the jewel in the hole by causing the outer perimeter of the hole to be yieldingly enlarged and then, allowing the perimeter of the hole to return to its original shape and size, thus causing the jewel to be caught in the circumferential slot on the inner wall of the hole.
A method of setting at least one jewel in an object which is of an elastic material comprising the steps of:
- forming a plurality of projections on the circumference of a position where a hole is to be made in the object;
- making in the object, a hole which corresponds to the jewel in shape, but is somewhat smaller than the largest diameter of the jewel;
- making a circumferential recess at least in part in an inner wall of the hole and in an inner wall surface of said projections, the recess having a diameter larger than the largest diameter of the jewel;
- and
- press-fitting the jewel in the hole by causing the projections to be yieldingly withdrawn and then, allowing them to return to their original position, thus causing the jewel to be caught by the recess in the circumferential projections around the hole.
A method of setting at least one jewel in an object which is of an elastic material comprising the steps of:
- forming an annular projection on the circumference of a position where a hole is to be made in the object;
- making in the object, a hole which corresponds to the jewel in shape, but is somewhat smaller than a largest diameter of the jewel;
- making a circumferential slot at least in part in an inner wall of the hole and in an inner wall surface of said annular projection, the slot having a diameter larger than the largest diameter of the jewel;
- press-fitting the jewel in the hole by causing the annular projection to be yieldingly expanded;
- and
- allowing said annular projection to return to its original shape and size, thus causing the jewel to be caught by the annular ring around the hole.
