8 Claims.

My invention relates to improvements in jewelry ornaments particularly of the type having a portion actually simulating a gem or a cluster of gems, as often referred to in the trade as pav or gem paved.

As stated and shown in my joint Patent No. 2,246,399 for Jewelry ornament, when lmaking such gem simulating surfaces in the prior art, said gems have only been simulated by providing indentations in the ornamented surface. An indentation is the complement of what is actually seen in a gem and an indentation therefore never gives the perspective eiect provided by a gem. I may simulate a gem by providing a, gem simulating mound comprising a multi-faceted frustopyramidal mound with the facets of the mound inclined similarly to those of the gem to be simulated. While these may be manufactured by the casting method shown in said patent and as shown herein, it is obvious that such a type of ornament is new no matter how made.

A further feature of my invention is that I provide a gem simulating portion comprising a center portion consisting of a plurality of similarly inclined facets arranged in pyramidal, preferably frusto-pyramidal, formation. Said formation comprises a cavity or a mound and a border portion consisting of a plurality of similarly inclined facets arranged in reverse frusto pyramidal formation around said center portion with the facets of the center and border portions being similar to the gem being simulated, whereby the upwardly and downwardly tilted facets may visually cooperate with each other to simulate a gem. So far as I am aware, I am the rst to provide a gem simulating ornament covering this combination of reversely inclined center and border facets and it is apparent that this combination much more accurately simulates a gem than a mere indentation as shown in my joint Patent No. 2,246,399.

A further feature of my invention resides in the fact that the arrangement of center portion and border portion actually simulates the facets on an actual stone for perspective effect, a feature not possible in prior art structures.

A further feature of my invention is to provide a plurality of such portions, each plurality being closely nested together as to provide a pav or a gem paved surface regardless of how it may be made.

Further features of my invention relate to improvements in the apparatus for and method of making my improved ornament.

These and such other objects of my invention as may hereinafter appear will be best understood from a description of the accompanying drawings which illustrate embodiments thereof.

In the drawings, Fig. 1 is a plan View of a jewelry ornament con-- structed in accordance with my invention in which the facets of the border portion project n outwardly to form mounds and the Vfacets of the center portion incline inwardly to provide cooperating indentations. l

Fig. 2 is a sectional view taken along the line 2--2 of Fig. 1. l

Fig. 3 is a perspective View of a single gem simulating mound.

Fig. 4 is a sectional view similar to Fig. 2 of an ornament constructed in accordance with my invention wherein the facets of the border portion are inclined inwardly and the facets of the center portion are inclined outwardly.`

Fig. 5 is a :perspective view of a single gem forming portion constructed as shown in Fig. 4. Fig. 6 is a perspective view of'an alternative type of ornament constructed in accordance with my invention. i

Fig. 9 is a sectional View taken through the front plate of my improved mold along the line 99 of Fig. 3 with a single facet forming pin removed. g l

Fig. 10 is a cross-sectional View of the front and back plates of the mold and also showing the ornament in section after the ornament has been formed by the cooling of the metal poured in between the mold plates in the manner shown in said patent and showing the back die :plate being removed from the front die plate containing the cast ornament. i a

Fig. 11 is a cross-sectional view of a front die plate `capable of producing the article shown in Fig. 4.

In the drawings, wherein like characters of reference generally indicate like parts throughout, 2l! and 20v generally indicate an ornament constructed in accordance with my invention. Although as stated I obtain good results by casting my improved ornament, it is believed the sub.- ject matter thereof is novel no matter how made whether by casting, stamping, burnishing or otherwise. Said ornament is provided with a gem simulating ornament surface'22. While said surface may comprise that of a single gemas shown at 22a in Fig. 6, it preferably comprises a gern paved surface extending throughout a substantial predetermined area of the ornament surface as the surfaces 22 shown in Figs. 1 and 6. Said surface Y22 whether comprised of a single gem or a plurality of gems has either a single gem simulating portion 24 or a plurality of gem simulating :portions 24 making up a gem paved ornament surface 22. Each gem simulating portion comprises a center portion 26 and a border portion 28. The border portion 28 consists of a plurality of similarly inclined facets 32 arranged in frustc-pyramidal formation. In the embodiment shown in Figs. 1 to 3 the facets project upwardly in true frusto pyramidal formation providing a mound. In the embodiment shown in Figs. 4 and 5, the facets 32 of the border portion 28' incline inwardly to form the reverse frustopyramidal formation or indentation 2G. As stated hitherto, so far as I am aware it is new to provide the pyramidal mounds 28 hitherto described.

As also'stated, a main feature of' my invention consists of providing a center portion 26 comprisinga plurality of similarly inclined facetsS arranged in reverse frusto-pyramidal formation to thatV of the facets 32 of thev border portion. Thus, in the embodimentl shownin Figs. 1 to 3, said .facets'30 form a cavity or concave crater having preferably a flat center portion 34 and in the embodiment shown in Figs. 4 and 5, said facets 30 form a mound 26' preferably having a flat center portion 34. Said center portions therefore comprise the preferably flat centerportions 34 and 34' and the facets 30 andr30' arranged around the center portion in frusto-pyramidal formation Whether the facets incline d-ownwardly to form indentations 26 as shown in Figs. 1-3 or upwardly to form center mounds 26 as shown in Figs. 4 and 5. It is thus obvious that in either embodiment the facets 30 or 30 of the center portion 28 or 28 incline in reverse frusto pyramidal formation to those 32 or 32 of the border portion 26 or 2S'. The gem simulating portions 24 or 24', where Aa pav surface-22 is desired, are preferably the highly reflective brilliant border facet forming surfaces 36 and center facet forming surfaces 38 may be readily transferred from the highly burnished facets 40 forming the border portion 42 of a die, said facets in said border portion being formed as mounds 42 in the embodiment shown in Fig. 1l or as cavities 42 in the embodiment shown in Fig. right in the die itself. The facets of the center portion 26 may as shown in said application be transferred from the highly burnished facets 44 on the ends 46 of suitable pins 48 projecting through suitable holes 5D in spaced reso closely nested as to have the outer walls of It is thus obvious that this double set of facets 3l) and 32 or 3D and 32 more closely simulate the gem than any prior gem simulating portion in a gem simulating ornament.

The gem simulating portions 24 or 24 may be arrangedgin stripes, scrolls, circles, leaves or any other well known design known in the art.

It is apparent that the pav surface 22 maybe formed .in regular hexagonal relationship all over the pin surface 22 as shown in Figs. 1-3 or it may comprise the irregular pav surface of a leaf as shownin Fig. 6.

As also stated, the idea of providing mounds in gemv simulating` portions ofV this description is broadly new no. matter how made and the combination` of oppositely inclined facets making up the center and border portions is also broadly new however made.

I have found, however, a convenient method of manufacturing such ornaments is by casting as shown in my joint Patent No. 2,246,399 in which lationship within a die 52 shaped as hereto described to form the outer border facets 32 or 32', as shown in Figs. 9 and 10 and thus the ends 4S of the pins 48 project upwardly in frusto pyrami- .dal formation. As shown in Fig. 1l the center facets project downwardly to form an indentation 46 in the upper end of each respective pin 48.

A suitable respective front plate 52 is shown in Fig. 8 and a suitable respective back plate 54 is lshown in Fig. '7. Said plates are provided with hemi-funnel indentations 56 extending from the upper ends 58 thereof and arranged in suitable relationship to guide molten metal into the mold cavity 68 formed in the front die plate. Thus when the front and the back plates are arranged in juxtaposition, a conduit will be provided leading to the mold cavity 6D. The front die plate 52 is provided with suitable aligning projections 62 adapted to project into suitable aligned cavities 64 in the back die plate to keep the plates in alignment as the metal is cooled in the mold cavity 60. It is apparent that an ornament 20 or 20 is cast within said cavity and may be suitably removed from said cavity after the relative movement of the back plate 54 away from the front plate 52 as illustrated in Fig. 10. If desired, the outer wall of each pin 48 is preferably corrugated as shown at 66 to provide a plurality of spaced grooves for the withdrawal of air from the cavity as the molten metal is being inserted as shown in said patent. It is apparent that thefacets 40 or 40 and 44 or 44 of the cavity form cooperating facets 32 or 32 and 30 or 30' of the border and center portions resectively of each gem simulating portion 24 or As also stated, the ornament may be made of any desired shape and the gem simulating portions may be made to simulate any shaped gem and arranged in any desired shape or relationship. Facets may be so formed as to simulate different cuts or forms of gems. Where the ornament is made by casting, any suitable type of low melting point metal or plastic may be employed. -A typical meta1 may therefor comprise 90 per cent tin and remainder of antimony, cadmium and/or lead in suitable proportions.

It is understood that my invention is not limited to the specific embodiments shown and that various deviations may be made therefrom without ldeparting from the spirit and scope of the appended claims.
