TITLE
A method of using a highly detailed, three dimensional, original,
jewelry model to produce two different, thin walled, light weight
expendable, thermoplastic replicas, castable in metal.
TECHNICAL FIELD
The technical field of the invention relates to using a highly
detailed, three dimensional, jewelry model to produce two
different, thin walled, light weight, expendable, thermoplastic
replicas of the model, castable in metal, with one replica having
the same direct frontal viewing aspect as that of the model and
the second replica having a direct frontal viewing aspect of
180 degrees opposite to that of the model, a result commonly known
in the jewelry industry as the left and right versions.

BACKGROUND OF THE ART
Presently the jewelry industry uses three main methods to produce
two different direct frontal viewing aspects of a master model.
A brief description of each method follows.
Method one consists of providing a master model with a form and
details having a direct frontal viewing aspect in either a left
or right direct frontal viewing aspect then producing a copy of
the master in a direct frontal viewing aspect of 180 degrees
opposite to that of the master model, using conventional jewelry
productionmethods or mechanical production methods, in each case
it is a very time consuming procedure where reasonably accurate
results can only be obtained with very simple designs.
Method two consist of bonding two sheets of a model producing
material, cutting out two basic forms, altering the forms, filing
soldering, the two forms together and as the first method it is
a very time consuming procedure and is limited to relatively
simple designs.
Method three consists of the production of two separate metal
stamping dies, one for the facing right version and one for the
facing left version and is limited to the production of plain
designs, free of any sharp angles or undercuts, production of
the dies is expensive and can only be justified where the
production of very large volume is involved.

The jewelry industry has spent much time and expense in the
search of an efficient method to reproduce the form and details
of complicated, three dimensional models, in a thin walled,
light weight, replicas of the model, with one replica facing in
a direct frontal viewing aspect as the model and the other replica
facing in a direct frontal viewing aspect of 180 degrees opposite
to that of the model without success.

SUMMARY OF THE INVENTION
The present invention relates to a method of using a highly
detailed, three dimensional, jewelry model and reproducing it's
form and details in two different, thin walled, light weight,
cast metal replicas, with the first replica having the same
direct frontal viewing aspect as that of the model and the second
replica having a direct frontal viewing aspect of 180 degrees
opposite that of the model and the first replica.
The summary will use a model with a selected direct frontal
viewing aspect facing left, however a reader will note that a
model with a direct frontal viewing aspect facing right will
produce identical final results by reversing the'. steps of the
method.
According to one feature of the present invention is that of
using a highly detailed, three dimensional, jewelry model with
a direct frontal viewing aspect facing left 100 of fig.1, and
securing the model on a flat surfaced base 101 of fig. 1.
According to another feature of the present invention is that of
providing a compatible, flexible, interchangeable, upstanding
mold producing frame 102 of fig.2.
According to another feature of the present invention is that of
placing and sealing mold frame 102 on the surface of base 101.
According to another feature of the present invention is that of
filling half of mold frame 102 with a pourable, air exposure
setting, silicone based compound. that produces a pliable female
counterpart mold 103 of fig.2, with a cavity that reproduces the
form and details of model 100 of fig-1, in a recessed, down,
facing left aspect 103.
CA 02597709 2009-10-27
According to another feature of the present invention is that of
withdrawing mold 103 of fig.2, from mold frame 102 and inverting
it from the top edge to the bottom edge then reinserting it into
mold frame 102, that alters the reproduction of model 100 of fig.1
5 from a recessed, down, facing left aspect into a recessed, up,
facing left aspect 104 of fig.3.
According to another feature of the present invention is that of
filling the remaining half free space within the mold frame 102
with a pourable, air exposure setting, silicone based compound
that produces a pliable male counterpart form 105 of fig.3, that
reproduces the form and details of model 100 of fig.1. in a raised,
down, facing left aspect 105.
According to another feature of the present invention is that of
removing the male form 105 of fig.3, from the mold frame 102 and
inverting it from the top edge to the bottom edge then reinserting
it into mold frame 102, that alters the replica of model 100
from a raised, down, facing left aspect 105 of fig.3, into a
raised, up, facing left aspect 106 of fig.4.
According to another feature of the present invention is that of
filling the remaining half free space within mold frame 102 of
fig.4, with a pourable, air exposure setting, epoxy based compound
that produces a rigid female mold that reproduces the form and
details of model 100 of fig-1, in a recessed, down, facing left
aspect 107 of fig.4.

it from the top edge to the bottom edge 108 of fig.5, that alters
the replica of model 100 of fig.1, from a recessed, down, facing
left aspect of 107 of fig.4, into a recessed, up, facing left
aspect 108 of fig.5.
According to another feature of the present invention is that of
forming a thin, expendable, thermoplastic sheeting into the
cavity of mold 108 of fig.5, that produces a reproduction of
model 100 of fig.l. in a recessed, down, facing left aspect 109
of fig.6.
According to another feature of the present invention is that of
inverting the f0xmed model replica 109 of fig.6, from the top
edge to the bottom edge, that alters the recessed, down, facing
left aspect of the model into a raised, up, facing left aspect
110 of fig.7.
According to another feature of the present invention is that of
trimming of any unwanted excess material from the formed model
reproduction 110 of fig.7, that produces an accurate replica of
model 100 of fig.1, in a raised, up, facing left aspect 111 of
fig.8, ready to be cast in metal.
Accordinb to another feature of the present invention is that of
using the silicone based female mold 104 of fig.3, and inverting
it from the left side to the right side, that alters the replica
of model 100 of fig.1, from a recessed, up, facing left aspect
104, into a recessed, down, facing right aspect 112 of fig.9.
