June 13, 1950 L STUEMPGES C. ENGRAVING DESIGNS IN BODIES OF TRANSPARENT PLASTIC COMPOSITION Filed April 26, 1948 INVENTOR.
6/4/94 1.. Sfuempyes Patented June 13, 1950 UNITED STATES PATENT OFFICE ENGRAVING DESIGNS IN BODIES OF TRAN S- PARENT PLASTIC COMPOSITION 8 Claims.
This invention relates to articles, such for instance as costume jewelry, which are formed from bodies composed of a transparent thermo-plastic material and which are characterized by having carved into the rear face thereof a cavity portraying the figure of a flower or other piece of art work arranged and adapted to stand out in relief when viewed from the front through the transparent body of the plastic. The invention has as its object the provision of a method of perfecting the art work in an article of this nature, and such, more especially, as will develop unusual realism in the appearance of the produced figure which the art work portrays.
Generally stated, the invention resides in a novel technique of filling the cavity, and in colortreating both the wall surfaces of the cavity and the fill material, to give to the viewed figure a translucent quality and an appearance of solidity which has been lacking in previous articles of this nature.
The invention consists in the method of manufacturing an article of the described character, and in the product of said manufacture.
In the accompanying drawing:
Figure 1 is a top plan view of a transparent thermo-plastic body produced in accordance with the teachings of the present invention.
Fig. 2 is a transverse vertical sectional view thereof on line 22 of Fig. 1; and
Fig. 3 is a sectional view similar to Fig. 2 showing the cavity carved in the back face thereof prior to the introduction of the filling material thereto.
In the practice of my invention the body of material which is to be carved is denoted generally by the numeral 5 and is or may be a rectangular solid composed of any suitable transparent plastic material as, for example, methylmethacrylate. The carving is performed in the back face of the body, and is such as will produce cavities 6 outlining any desired art figure, the figure which I have elected to illustrate being that of a rose and showing a flower or flowers in association with several clusters of leaves. The produced cavities, and which are usually in a connecting series, are thoroughly cleaned, and I then pour or press therein a filling I comprised of finely granulated particles of a suitable thermoplastic substance, of which one example is the particulated moulding substance composed of Lucite grains and commercially available as Crystal H-7500 HG-l, Fine Gran.
In performing this filling step, the powder need ordinarily be applied only to the cavities which define the flowers, leaving the leaf and stem cavities open, and this may be explained by pointing out that the leaves and the stems, when later tinted to a green color of suificient intensity to give visual realism, retain little of the transparency which characterizes the more delicate pastels which I apply to the flower cavities.
The next step in the process is to apply said coloring. The coloring agent is desirably one compounded by dissolving powdered Ciba dyes (an analine dye) in water and acetone, and this coloring fluid is applied in the instance of both the filled and the non-filled cavities by the use of hypodermic needles. The technique is to touch the point of the needle to the wall surface of the cavity and deliver thereto minute quantities of the various required colors, working progressively over the entire face of the cavity and using different dyes as may be required to obtain the desired color effect, and an artist experienced in performing this work can complete the entire design in a surprisingly short period of time. Within the filled cavities, the needle is perforce inserted through the filler material and there develops a certain amount of bleeding as the coloring fluid diiTuses itself through the compacted mass of granular material, this diffusion being quite beneficial in point of giving to the ultimate picture the translucency fo which the present invention strives. The acetone contained in the coloring fluid performs a desirable bonding function upon the grains Of plastic contained in the cavities. It is here pointed out that the granular particles, while they are preferably in a clear colorless condition when applied to the cavities and are then tinted by .the diffusion action of the injected coloring fluid, might conceivably be introduced as pre-dyed grains although a picture produced by this method might lack the detail of the needle-coloring step and would in any event require unusually painstaking care in the selection and placing of the pre-dyed grains.
The final step of the process is to integrate the granular particles by subjection to heat, and a 45-minute baking interval under a temperature condition approximately 200 F. accomplishes this end. While this heating step securely bonds the myriad grains of plastic filler, the granular form of the component particles is substantially unaffected and it is these thousands of minute grains, which each individually gather and reflect light, which are responsible for giving to the pictured flowers a unique and extremely attractive quality of translucency quite realistic of a express reference is herein made might be satisfactorily used without departing from the spirit of the invention and I accordingly intend that.
