PROCESS OF MOUNTING METALLIC ORNAMENTS UPON GLASS, 8w.

SPECIFICATION forming part of Letters Patent No. 479,743, dated July 26, 1892.

Application filed February 13, 1892. Serial No. 421,459. No specimens 1'0 (1 whom it may COIL-(1877b:

lie it known that we, CHARLES ii. llEADLY and JOHN S. (JARRow, citizens of the United States, and residents of Philadelphia, Iennsylvania, have invented an Improved Process of Mounting Metallic Ornaments upon Glass and Similar \Vare, of which the following is a specification.

The object of our invention is to so mount metallicopen-work upon glass.-ind similar material in such a manner that after the article has been plated the solder joints are not exposed, but are plated similar to the body of the material. This object we attain in the following manner, reference being had to the accompanyingdrawings, which illustrate the different steps in the process, and in which Figure 1 is a view ofone form of ornamentw tion as it is cast ready to be shaped to the form of the article. Fig. is aside view of a glass bottle towhieh the ornamentation shown in Fig. l is to be applied. Fig. I is a view showing the n'namentation partially applied to the bottle. Fig. l is a view showing the ornamentation removed from the bottle, but shaped to conform to the body thereof, and ready to be immersed in the whitening-bath. Fig. 5 is a view showing the ornamentation again applied to the bottle and the upper edges soldered together, so that it cannot be removed therefrom; and Fig. 0 isa view showing the bottle with the ornamentation immersed in an electroplating solution.

It will be understood that similar material to glass can be used without departing from our invention, the word similar in this instance meaning any material which can be immersed in an electroplating solution without taking. the electroplating, and it will also he understood that the design shown in the accompanying drawings need not be adhered to in carrying out our invention, and that the shape of the article upon which the ornamentation is mounted is immaterial.

The first step in the process is to mold the open-work ornamentation. This is done by producing a ilat mold of the design required, and the sections a can be made singly or in pairs or cast in a single piece, as desired. The material preferably used is white-metal, which is suflicicntly pliable to enable the manufacturer to bend it and shape it to the article. The design in most instances where a large number of the same article are to he made is made for that one article; but where a small number of a certain article is to be made the open-work ornamentation may he cut from a large casting.

The operator mounts upon the bottle 1 (shown in Fig. 3) the ornamentation shown in Fig. l, soldering the two edges of the ornamentation together at 1,1 and when the ornamentation extends under the bottle, as is the case of the design shown in the drawings, the operator turns the extensions 1/ under the bottle and solders them together, as will be clearly understood by referring to Fig. 1. The extensions 1, however, are preferably left, as shown in Fig. 3, so that the ornamentation after being soldered can he removed from the article, as shown in Fig. t. It isthen dipped into a quicleacting platingsoltltion, and when silver-plating is applied the entire structure is Coated. It is then removed from the 0100 troplatingdiath, and the white coat on the outer portion of the open-work is then removed hy hurnishing. The article is then prepared for the final electroplating-bath, thus leaving the white coating only at the back, as in most cases where glass. is used the back of the tH'iHtlllUlliillltJll can be seen through the glass. The plating covers up or removes any dark spots on the hack of the ornamentation which would otherwise show through the glass and spoil the appearance of the article.

The next step in the process is to mount the ornamentation upon the bottle, turning down the edges (3, as shown in Fig. .1), and curing them together by solder joints at. f, as indicated in Fig. 1, thus securely fastening the ornamentation upon the bottle.

The next step in the process is to immerse the bottle or other article, with the ornamentation secured thereto, in the electroplating solution,as shown in Fig. (I, preferably a slowacting solution, so as to thoroughly plate all of theornamentation,includingthesolderjoints. The article is then removed from the solution and thoroughly cleaned and polished, ready to be placed upon the market.

Thus by our improvement we are enabled to m.-t||n|'.n-tl|re illlltflt'. oi lllt tllill'ili'lt'l' le- Mllllt'tl at a rontparatirol ;small t'osLantl the solder joints will he plated and will haretho saute il|)1)t'ttl;l!itt a the liollyol lho ornamentation,

in some instant-es when opaque glassware or similar material is used the whitening step in the [\t'tn't'ss may he dispensed with.

When large numliers of the same ;llll('l( are to he mounted with the same ornamentation, a dummy or l'ornn-r can he used toshape the ornatm-ntalion in the first place without depart ing from our invention. The ornamen tation, however, is finally seenred to the artiele for which it is intended.

\Ve claim as our in\'eution 1. The withixrdeserihed process of ornamenling glassware or similar material, said process consisting in casting the metallic open-work ornamental design, fitting it to the article to he ornamented, soldering ittogethe: at the joints, sulrjecting it. to an electroplatingsolution, which will plate the metallic ornamentation and the solder joints without plating the artiele, suhstantially as set forth.

2. The within-deserihed proeess of ornainenting, glassware or similar material, said process eonsisting in (tasting the, metallic open-work ornamental design, fitting it to the arti -le to be ornamented in such a manner that it ean be withdrawn from the artjiele, solder ng it together at the joints, removing it from the art iele, sulrieeting it to a plating solntion in order to plate the haek ol' the ornamentation, mounting it again upon the arti- ('l(, turning down and fitting and soldering together the remaining portion of the ornamentation so as to eonline it to the article, and finally immersing the article, with the ornantentattion, in an electroplating solution which will plate the metallicornamentation without plating the article,substantially as specified.

$5. The process herein described of ornamenting glassware or similar material, said process consisting in first casting a design in white-metal and having tapered portions to fit over a shoulder, mounting said ornamentation upon a form, seeuring the edges together by solder, immersing the article, with the ornamentation, in an electroplating bath, whereby the ornamentation and soldered joints are plated without plating the article, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two suhserihing witnesses.
