To all whom it may concern.

Be it known that I, JOHN E. MILLER, a citizen "of the United States, and resident of lVashington, in the county of lVashingtofore been accomplished both by pressing and by cutting. When pressed, the configuration is impressed in the surface of the article simultaneously with pressing the latterl As such articles are ordinarily firepolished, the pressed configuration must be sufficiently deep or pronounced to maintain its form notwithstanding the appreciable melting of the surface incident to fire finishing. It is not practical to impart fine or very shallow ornamentation by pressing for the reason thatit is diflicult to maintain in the mold sharp and clear lines of fine or shallow character, and for the further reason that the, operation of fire finishing tends to blur and efface such fine or shallow configuration. Hence, the only efi'ective way to apply the latter is to cut the same. into the surface of the glass after the article has been fire polished.

The primary purpose of the present invention is to utilize and so combine these two methods of embellishing a glass article as to provide a grade of ware intermediate so-called pressed glass andcut glass wherein those portions of the embellishment that are unimpaired by the fire finishing operation are given their. ultimate form simultaneously with pressing the article, and then after the latter has been fire finished the remainder of the embellishment, i. 6., those portions too shallow or too delicate to with stand the fire finish, are cut into the surface. And in those types of ornamentation in which both forms of embellishment are utilized in the same configuration, the

one into the other in suchmanner as to cut surface white or opaque, and the process of-grindingand polishing the cut surfaces to restoretheir transparency and to develop the luster characteristic of cut glass is a laborious and expensive operation. WVith the kind of ornamentation herein proposed, the pressed portion of the configuration is not dimmed or blurred at any time, but on the contrary, its luster is increased by the fire finishing operation. It is, therefore, only necessary to grind and polish the lighter and shallower portions of the configurations that can be effectively formed only by cutting. And as to these, some or all may remain opaque in accordance with the decorative scheme that may include more or less of the frosted or opaque effect.

- duce prismatic effects and in which the formation of lines liable to be blurred by the fire-finishing operation are, as far as pos sible, avoided. While the invention is not limited in this regard, the best results are had when the precautions noted are observed.

For the purpose of illustrating the invention, I have shown in Fig. l of theaccompanylng drawings a portion of a" shallow nappy or plate in which the relatively deep portions of a decorative scheme are shown' in the o'uter surface thereof,'the same'having been pressed simultaneously with pressing the article, the mold, not shown, being of proper configuration. Fig. 2 is a similar view of the same portion of the article showing the finer or more shallow portions of the ornamentation which have been applied by the ordinary processes of cutting. Figs. 3, 4c and 5 are fragmentary sectional views taken'on-lines 33, 1- 1: and 55, respectively, of Fig. 2.

Referring to, the drawings, 2 designates a portion of a glass article to be embellished, and 3 are parts of the configuration that are of such form and of sufiicient depth to permit of being formed by pressing. -The article 2, commonly known as a .blank, and

.the pressed configuration 3 are formed by on. In the most economic practice the out portions are the finer or shallower parts of.

the configuration, such for instance as stems '4: for the pressed leaves or petals 3 of the ornamentation here illustrated. Also, the embellishment maybe elaborated by cutting the flower-like figures, such as shown at 5, the same being provided with a cut stem 4 to harmonize with the combined spray and flower design.

The operation of cutting leaves the cut surface opaque or of a frosted appearance which is represented by the shading of the petals of flower or blossom 5. And the same frosted effect is characteristic of all of the cut lines 4 here shown, the frosting having been obliterated by subsequent grinding and polishing. vIt will be of course understood that the frosted effect may be permitted to remain in any out portion of the design in which such effect is desired, and to that extent decreasing the cost by eliminating the grinding and, polishing necessary to remove it.

It is characteristic of the invention that those portions of the configuration that are not blurred or harmfully affected by the fire-finishing operation are produced and given final form by the initial pressing step and require no further work, and that only such portions of the configuration are cut as will not effectively withstand the heat of the glory hole. /It will be understood, however, that deeper portions of the design may be formed entirely by cutting, at the option of the manufacturer.

By utilizing'bot-h pressing and cutting in the production of a siirface configuration, a highly decorative grade of ware 1s produced at comparatively small cost in which the major portion of the work is accomplished in the mold and in which the effective charactertistics of both pressing and cutting are so combined as to produce a comparatively inexpensive glass article of high artistic quality.

I claim 1. A glass blank having fire-polisheddepressions so located as to form the deeper portions of an incomplete decorative figure which may be completed by cutting.

2. A glass article embellished with a pressed decorativefigure, the deeper'portions of which have fire-finished surfaces andthe shallower portions of which are-cut.

3. A glass article having ornamental depressions of diiferent depths, the surfaces of the deeper depressions being fire-finished and the surfaces of the shallower depressions being cut, the deeper and shaller depressions combining to produce a complete described of dec the said depressions and with said depressed and cut surface portions combined in the same decorative figure.

6. The method of forming and embellishing a glass article consisting in shaping the article and simultaneously forming depressions in the surface thereof, fire-polishing the article including said depressions, and completlng the embellishment by cutting other depressions in ,such surface which combine .with the fire-polished depressions to complete a decorative figure.

7. The method of forming a glass article and embellishing the same with depressed configuration having relatively deep and relatively shallow portions, consisting in shaping the article and; simultaneously forming therein the relatively deep portions of the configuration, and then completing the embellishment by cutting the relatively f shallow portions of the configuration.

8. The method of forminga glass article and embellishing the same with surface configuration, a portion of the-configuration being of'a character to withstand fire-finish /pleting the-embellishment by cutting the JAMES I. BROWNSON.
