SPECIFICATION forming part or Letters Patent No. 605,185, attenuante lees.

Jersey, have invented certain new and useful Improvements inrushes, Mirrors, dto., of which the following is a full and true description, reference being had to the accompany'- ing drawings. Y

The object of my invention is to provide articles, especially those wholly or partlycom-.

posed of plastic material, with ornamental trimmings of metal, which may be readily and economically applied to the articles.

My invention may be practiced in connection with many dierent articles, among which may be mentioned brushes, mirrors, picture-frames, paper-cutters, blotter-holders, ornamental glassware, calendar-holders, thermometerframes, penholders, knife and fork handles, 85o. In the accompanying drawings I have illustrated its use in connection with brush-backs- Figure 1 is a top vieW of a brush-back made by following out my invention. Fig. 2 is a longitudinal sectional View of the same, showing part of the silver trimming in perspective. Fig. 3 is a longitudinal sectional view of the metallic ornalnental trimming to be applied, partly shown in perspective. Figs. 4 and 5 are longitudinalsectional views of the top half-shell and lower half-shell of the brushback before they are assembled, Fig. 4 being partly shown in perspective.

In carrying out my invention in connection with brushes I provide the lower half A of a brush-shell, (as it is technically knowm) in which the bristles have been inserted, and then cover the ends of the bristles within the shell with a waterproof composition B. Over this I place the upper half C of the brushshell. This half C is composed of a molded material and is securely attached to the lower half A of the shell in any of the usual Ways. Preferably, however, both halves are composed of a compound of pyroxylin and are securely united by an interposed cement, also composed of a pyroxylin composition placed between the meeting edges of shellsA and C, all the parts being further united under pressure.

Appneaiai mai rtru'ny' r2, isdn serai Nt. analogs. idro moda In order to insure a proper fitting of the half-shells A and C, there is a recess a formed in the part A and coacting lug c formed on the edge of part C. The outer surface of the half C isV irregularas distinguished from a substantially evenV and smooth surface, and this irregularity may constitute va design in 'r `laliel;`.A 1n `practice the design` may be given to'thesurface of ,thehalfshelLC at the time ,that said half-shell is molded; but, if desired, the irregularities on the surface maybe made after the half-'shell is made and before, during, or after its attachment to the lower half A of the shell. The intention being to hide the surface of the half-shell C, it need not be carefully nished or ornamented, the object of the depressed and elevated portions on the surface being to support corresponding de-` pressions and elevations formed upon the in ner surface of an applied metallic trimming D. It is not necessary, however, that theindentations and raised portions of the applied trimming D shall correspond exactly with the raised and indented portions of the half-shell C, but they should (in order to achieve the object of my invention) correspond sufficiently to furnish the required support.

The metallic trimming may cover the Whole or any portion of the surface of the half-shell C. The trimming is formed ofthin sheet metal-silver, for instancewith its outer surface ornamented by figures or foliage in relief, the opposite side of the sheet being formed with depressed and raised portions, the depressed portions of one side of the metal being opposite the raised portions of the other side. The depressions of the inner side of the metallic trimming fit approximately upon the elevated portions of the surfaceof the halfshell C, which thus supports the thin `shell and causes it to retain its shape While being used. A f

If desired, the surface of the half-shell C may exactly iit the inner surface of the trimming, in which event the metal may be eX- ceedingly thin.

The metallic trimming is secured to the surface of the article in any Well-known manner-by means of a cement or, as shown in Fig. 2, by overlapping the edges of the brush- IOO back. If a cement is used, it should be one which readily adheres to both the metal trimming and the brush-back. If the back is composed of a pyroxylin compound, the cement should also, for the best results, be a pyroxylin cement.

In the drawings I have shown the attachment of the trimming by bending the edge E down under the half-shellA. In addition to this the cement may be used.

- I am aware that it has been proposed to apply metallic trimmings to molded articles by securing the same withl a cement or tacks. If the trimming is quite thin and even and has an ornamental surface in relief, it has been found that the unsupported parts soon become dented or depressed, and the appearance of the trimming is marred. This defect I overcome by providing the molded article with raised portions which support the ornamental trimming at all points.

My invention is also quite distinct from the molding methods heretofore practiced. In those methods the operator has attached the trimming to the article by the aid of pressure; but it has not been possible to use thin trimmings Without marring the design. In addition, the use of such processes could not be extended to include many common articles, including finished brusl1es,because the shapes of such articles prohibited the use of pressure at all points.

The new method of manufacture which I have discovered is also advantageous as compared with the processes of electroplatin g heretofore practiced. Aside from the facts that many moldable compositions are inj uriously affected by the plating solutions and that brushes have to be treated with great care in the bath, my invention dispenses with all of the nishing operations necessary to make the electroplated articles satisfactory to the trade.

My invention is not coniined to the use of pyroXylin compositions, but includes supports made of any material which have their surfaces formed with raised or depressed p01'- tions which support the depressed and raised portions of the trimming.

What I claim is- A back for brushes, consisting of (l) an upper half-shell which has suflicient raised portions to support a metal covering on its eX- terior surface, and (2) a lower half-shell into which the bristles are drawn or attached; both half-shells being composed of a pyroXylin compound and secured together at their meeting edges; in combination with an upper thin sheet of metal which approximately fits over the raised portions of the surface of the upper half-shell and has its edges folded over` upon the edges of the lower half-shell and is secured thereto, substantially as described.

In Witness whereof I have hereunto signed my name this 11th day of February, 1897.
