Chicago, 111;, a corporation of Illinois Application July 2, 1938, Serial No. 217,301 a 1 Claim. 7 (Cl. 41-18) In the form shown, the surface. finish of the present invention is applied to a metal recep-.

t'acle in. the form of. a hopper which. constitutes the ash receiving portion of a, smoking stand,

although the principles of the present invention may be employed in connection with receptacles intended for other uses In the construction of smoking stands it is desirable to provide a converging hopper down which the ashes are directed, which hopper will ordinarily be closed by a trap door leading to a waste can in the interior of the smoker, and in view of the uses to which the device is put it is desirable to impart to the surface of the hopper a hard metallic stainless finish which will not be subject to scratching or discoloration by heat, or by the lodgment of ashes, cigar butts or the like, andfor this purpose it has been customary to employ a chromium finish for these portions of the ash receptacle. Although the chromium finish, in a high degree, possesses the physical properties which well adapt it for the purpose stated, nevertheless, its glaring white and somewhat harsh metallic appearance may render its use on the more prominently exposed portions of the smoker objectionable as offensive to the taste of those who prefer a softer or warmer finish in an article intended for use in association with.

room furnishings.

In order to meet these requirements, the receptacle of the present invention is constructed of chrome finished metal, which exposesthe metallic surface on the interior of the hopper bowl but which is overlaid around the margin, and upon surfaces exposed to the exterior of the bowl, with a tinted lacquer finish in the form of a thin film of transparent colored lacquer tinted to a golden color, and which is practically indistinguishable in appearance from gold plating, so that the resulting hopper bowl around its margin and upon its exterior presents the appearance of a gold plated article having the soft warm color tones of gold, while upon the interior of the hopper bowl the metallic chromium surface is exposed.

The lacquer coating film is transparent and of such extreme thinness that there is no discernable break or offset along the edge of the lacquer surface which forms the margin line between the lacquered and unlacquered portion of the receptacle, with the result that the line of demarcation is indicated solely by the transition in color rather than by any apparent change in texture which either the hand or the eye can detect, The lacquer surface, therefore, presents no break or. irregularity. in the smoothness of the interior contour of the bowl, whichif present, might afforda ledge or shoulder for the accumulation ofashes. or. refuseand which will. thus be objectionable for practical as well. as aesthetic, '5 reasons. a v v Further objects. and. details will appear from the description of the invention in conjunction with the accompanying drawing, wherein Figure 1 is a perspective view of a smoker em- 10 'bodying the features of the present invention;

and

Fig. 2 is an enlarged sectional detail taken through the hopper wall and showing the lacquer coating applied to the margin thereof, it being 15 understood, however, that the thickness of the coating is necessarily greatly exaggerated, and that in practice the film of lacquer is much too thin to permit its accurate illustration in the drawing.

As shown, the receptacle of the present invention is in the form of a hopper iii, closed at its discharge outlet by a trap door H which may be operated in any convenient manner. The hopper as a whole is preferably formed of chrome g5 plated metal, although nickel plated metal may be employed as a substitute therefor. However, in view of the fact that it is desirable, Within the interior of the hopper bowl, to expose the metallic surface to meet the conditions of use, it is 30 desirable to employ a finish which will not tarnish or discolor, and for this purpose chromium is admirably adapted, since it will retain its brilliance indefinitely, while nickel, if exposed to the atmosphere, will tend to tarnish or become dull 35 within a few days.

The chromium (or nickel) surface is buffed I throughout to secure its characteristic brilliant finish, after which a lacquer finish, in the form of a thin film I3, is applied to the upper margin of the bowl l4 and around the exterior wall l5, aswell as to the handles 15 or other portions of the smoker which are intended to display a bright metallic appearance.

The lacquer employed is preferably of the clear or transparent synthetic baking enamel type to which a golden yellow dye or pigment has been added to afford the required color tone, so that the brilliance of the underlying chrome finish, transmitted through the transparent colored lacquer, affords a perfect simulation of gold plating and one whch it is impossible to distinguish by reason of variations in surface texture or the like, or by reason of any perceptable break along the edge of the lacquer coating. The smoker thus finished displays the appearance of one having a bowl chrome plated on its interior, with a gold plated margin stripe and gold plated exterior trimmings which are indistinguishable in appearance from an exposed metallic gold surface.

The softened color tones added by the lacquer finish lend themselves admirably to the finish of the smoker as a,- whole, since the Warmer tone of the gold color employed in the metallic trimmings blends admirably with the color tone for the remainder of the smoker, which will ordinarily be finished in fiat or non-lustrous colors or shades which contrast efiectively with the brilliance of the lacquered metallic trimmings.

By employing a lacquer finish throughout a limited portion only of the hopper bowl, and by exposing the metallic surface within the interior of the bowl, we are enabled to utilize the durable qualities of the metallic surface where such surface finish is desirable or necessary and at the same time to enhance the appearance of the marginal and exterior portions of the bowl and trimmings in a manner which in no sense detracts from the serviceability of the smoker for its intended use, and at the same time adds greatly which the chrome finish would not properly harmonize, or within which it might be offensive to the taste of certain discriminating users.

Although for purposes of adequate description the present receptacle has been described as the hopper of a smoking stand, it will be understood that a receptacle, similarly lacquered around its margin, might be advantageously employed for other uses in which a metallic exposure is desired upon the interior in order to increase its serviceability under conditions similar or analogous to those heretofore described.

We claim:

In a device of the character described one face of a section thereof having a brilliant metallic lustre throughout composed of a plurality of contrasting adjacent color tones characteristic of different metals, one of said color tones comprising a highly lustrous base surface of polished chromium and the contrasting adjacent color tone comprising a thin film of transparent yellow-tinted lacquer superposed on said highly lustrous chromium base surface over a limited area thereof, said lustrous base surface reflecting light through said lacquer and imparting thereto the color characteristics of gold.
