Abstract
Abstract A process and the resulting article of mass producing low cost fanciful ornamental figures for jewelry and jewelled articles and objects of art which involves the use of selected electrolytic ''''trees'''' or random metallic deposits made in an electroplating operation as a master in preparing a jeweler''s mold, then casting inexpensive metal or plastic material in the mold to produce reproductions of the master.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
92 words
In the art of manufacturing jewelry having a free-formed configuration, jewelled articles, and objects of art, the steps comprising: forming in a free-formed configuration metallic growths as a phenomenon of an electroplating process adjacent apertures in the insulation of a cathode conductor, selecting a particular one of such growth specimens, using the particular specimen as a master in preparinG a mold thereof, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental figure corresponding in form to the master.
Claim 2
Dependent Claim
92 words
In the art of manufacturing jewelry having a free-formed configuration, jewelled articles, and objects of art, the steps comprising: forming in a free-formed configuration metallic growths as a phenomenon of an electroplating process adjacent apertures in the insulation of a cathode conductor, selecting a particular one of such growth specimens, using the particular specimen as a master in preparinG a mold thereof, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental figure corresponding in form to the master.
Claim 3
Dependent Claim
100 words
In the art of manufacturing jewelry, jewelled articles, and objects of art having a free-formed configuration, the steps comprising: providing an electrolytic bath with an aperture in the insulation of a cathode conductor immersed in the bath, providing a random deposit of metal at the position of the aperture in the insulation of the cathode conductor to produce a three-dimensional free-form master, taking the master and forming a mold thereof, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental figure corresponding in form to the master.
Claim 4
Dependent Claim
100 words
In the art of manufacturing jewelry, jewelled articles, and objects of art having a free-formed configuration, the steps comprising: providing an electrolytic bath with an aperture in the insulation of a cathode conductor immersed in the bath, providing a random deposit of metal at the position of the aperture in the insulation of the cathode conductor to produce a three-dimensional free-form master, taking the master and forming a mold thereof, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental figure corresponding in form to the master.
Claim 5
Dependent Claim
64 words
In the art defined in claim 2, creating concurrently a multiplicity of deposits of non-precious metal on a free-formed basis through the electrolytic bath, selecting particular ones of the deposits for artistic quality and mechanical adaptability for the end product to be made, using the selected deposit or deposits as a master or masters, and following for each such master the remaining steps defined.
Claim 6
Dependent Claim
20 words
In the art defined in claim 1, forming the mold of rubber or rubber-like material, and casting pot metal therein.
Claim 7
Dependent Claim
20 words
In the art defined in claim 2, forming the mold of rubber or rubber-like material, and casting pot metal therein.
Claim 8
Dependent Claim
15 words
In the art defined in claim 4, the additional step of plating the ornamental figure.
Claim 9
Dependent Claim
15 words
In the art defined in claim 5, the additional step of plating the ornamental figure.
Claim 10
Dependent Claim
18 words
In the art defined in claim 1, introducing a plastic into the mold to produce the ornamental figure.
Claim 11
Dependent Claim
18 words
In the art defined in claim 2, introducing a plastic into the mold to produce the ornamental figure.
Claim 12
Dependent Claim
17 words
As an article of manufacture, an ornamental figure made in accordance with the process of claim 1.
Claim 13
Dependent Claim
17 words
As an article of manufacture, an ornamental figure made in accordance with the process of claim 2.
Claim 14
Dependent Claim
14 words
As an article of manufacture, an ornamental figure made in accordance with claim 3.
Claim 15
Dependent Claim
129 words
In the art of manufacturing jewelry, jewelled articles, and objects of art, the steps comprising: providing an electroplating bath with a cathode conductor having an outer insulation and a plurality of apertures in the insulation, passing an electrical current through the bath to produce growth specimens of a metal in free-form configurations at the apertures, selecting particular ones of the growth specimens in accordance with the appearance of their free-form configuration, arranging the selected specimens in the form desired for the finished article, soldering them together in such form to make a master, preparing a mold from such master, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental article corresponding in form to the master.
Claim 16
Dependent Claim
129 words
In the art of manufacturing jewelry, jewelled articles, and objects of art, the steps comprising: providing an electroplating bath with a cathode conductor having an outer insulation and a plurality of apertures in the insulation, passing an electrical current through the bath to produce growth specimens of a metal in free-form configurations at the apertures, selecting particular ones of the growth specimens in accordance with the appearance of their free-form configuration, arranging the selected specimens in the form desired for the finished article, soldering them together in such form to make a master, preparing a mold from such master, removing the master from the mold, and introducing into the mold a material in liquid condition which will harden to produce an ornamental article corresponding in form to the master.
Claim 17
Dependent Claim
46 words
The process defined in claim 13 which includes the preliminary step of obtaining the metallic growths by causing random deposits of metal through the electrolytic bath to be made in the region of the apertures in the insulation of the cathode conductor immersed in the bath.
