Abstract

A design for a jewel mounting structure employing a moveable setting. A jewel or other stone to be exhibited is set upon a mounting sleeve which is adapted to slideably move along a curved guide surface having a predetermined radius of curvature. A connector depends radially inwardly from the sleeve and is journeled about a shaft which lies at the center of curvature of the guide surface. Affixed to the journaling element opposite the connector and sleeve is a weighted enclosure which will cause the sleeve to rotate about the shaft until gravitational forces maintain the weighted enclosure at the lowest point of its circular arc. The jewel or other stone being exhibited will be capable of slideably moving across the guide surface but will tend to be maintained at a location based upon the positional relationship of the weighted enclosure.

Dependent claims

A jewel mounting structure comprising:

(a) a housing having an internal cavity and a substantially longitudinal opening at the top thereof;
(b) a shaft secured within the cavity of said housing and being disposed perpendicular to the longitudinal opening in said housing;
(c) a mounting guide including a guide portion having a uniform radius of curvature, said mounting guide being coupled to said housing within the opening therein, the interval between the guide portion and said shaft being equal to radius of curvature of said guide portion;
(d) a jewel mounting sleeve having a top and bottom surface and an opening therein, said opening being disposed about the guide portion, said sleeve being adapted to slideably move along the guide portion;
(e) pivot means for journeling said sleeve about said shaft, said means secured to the bottom surface of said sleeve;
and
(f) weighted means for counterbalancing said jewel mounting sleeve, said weighted means being coupled to said pivot means on the diametrically opposed side of said shaft.

A jewel mounting structure comprising:

(a) a housing defining an internal enclosure, said housing being substantially oval along both its major and minor axis, said housing including a substantially rectangular opening in the top thereof, the longitudinal axis of said rectangular opening being aligned with the major axis of said housing;
(b) a shaft secured within the enclosure of said housing across the minor axis of said housing and being perpendicular to the longitudinal axis of the rectangular opening;
(c) a mounting guide comprising a central guide surface having a uniform radius of curvature and bounded by parallel edges, said mounting guide being coupled to said housing, the edges of said guide surface being spaced from the edges of the rectangular opening in said opening, the interval between said shaft and said central guide surface being equal to the radius of curvature of said central guide surface;
(d) a jewel mounting sleeve having a top and bottom surface and an opening therethrough, the central guide surface being disposed through the opening in said jewel mounting sleeve, said sleeve being adapted to slideably move along said central guide surface;
(e) pivot means journeling said jewel mounting sleeve about said shaft, said pivot means secured to the bottom surface of said jewel mounting sleeve;
and
(f) weighted means for counterbalancing said jewel mounting sleeve, said weighted means being coupled to said pivot means on the opposite side of said shaft from said pivot means.
