May 13, 1930. i". M BANSFIELD PICTORIAL REPRODUCTION IN PLAQUE Filed Oct. 24, 1928 Patented May 13, `1930 PArEr OFFICE THOMAS M. BANSFIELD, QF CHICAGO, ILLINOIS IPICTOiR-IAL REPRODUCTION IN PLAQUE Application filed October 24, 1928. Serial No. 314,626.

This invention relates to pictorial reproductions in plaque. The invention has particular reference to the reproduction of works of art in metal, and relates especially to a distinct manner of finishing the surface of the reproduction. The invention is characterized by having the figures of the painting or picture reproduced, embossed or-raised in proper proportion and a distinctive feature of the invention resides in silver-plating the surface, and then using a shadowing material such as lampblack or powdered carbon, for example, to fill in the depressions and accentuate the embossed effect of the charactersor objects.

Thus, the invention is essentially embodied in a metal plaque having the characters or objects embossed or raised proportionately from the surface in the casting or pressing of the plaque, and the distinctive surface finishing which, as above mentioned, inheres preferably in a :precious metal plating by means of which the plaque is rendered much more attractive and also endurable.

Other objects will appear hereinafter.

f' The invention consistsin the combinations andvarrangements o f parts hereinafter described and claimed.

The invention will be best understood by forming a which: y

Fig. I is a face or elevational view ofk a part of this specification, and in typical plaque of the invention mounted in.

, a plaque base is employed which is prefer-r ably composed of copper or other endurable malleable metal. The base relief may be pre-' pared either by a casting or mould process. 'Referring particularly to Fig.,2 theplaque base 4 is mounted in a suitable frame 5 and held in placeby an appropriate backing 6.

reference to the accompanying drawings- As stated, the plaque base is preferably composed of copper or a cop'per alloy and the the silver or precious metal-plating for the surface is indicated at 7. Silver-plating the surface'by electro-plating isthe preferred 55 method and after the surface has been plated a shadow material such as lampblack or very nely powdered carbon, for example, is spread upon the surface as indicated at 8 in Fig. 2 and fills the depressions and crevices 00 to accentuate the embossing of the objects in the reproduction. After this powdered substance has been spread upon the finished surface of the plaque, as explained, it is brushed off, but in this `process the minute grains of G5 the powder adhere to the finished surface of the plaque in the depressions and orevices to produce a shadowing effect which greatly increases the attractiveness of the plaque.

` While I have illustrated and described the preferred form of construction for carrying my invention 'into effect, this is capable of variation and modification without departing from Vthe spirit of the invention. I, therefore, do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of such variations and modificatlons as eome'within the scope ofthe appended claims. l

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The process of making pictorial reproductions rn metal plaque form which consists m preparmg a base member in` embossed relief, having portions raised proportionately to the pictorial reproduction being made, and having depressions formed between the raised portions, plating the surfaceI with a metal coating, covering the plated surface witlra '9o powdered substance to ll said depressions, and then brushing the surface to remove surplus powdered material, leaving said material in the-.depressions to accentuate the relief.

, `2.`The process'of making pictorial repro- (95 ductions in metal plaque form which consists in preparing a base member in embossed relief, having portions raised proportionately to the pictorial reproduction being made,l and having depressions formed between the raised portions, plating vthe surface with a precious metal, covering the plated surface with a powdered substance to fill said depressions, and then brushing the surface to remove surplus powdered material, leaving said material in the depressions to accentuate the relief.

3. The process of making pictorial reproductions in metal plaque form which consists in forming a base member of malleable metal in embossed relief, having portions raised proportionately to the pictorial reproduction being made, and having depressions formed between said raised portions, electroplating the surface with a coating of metal, then spreading .finely powdered carbon or lampblack upon the surface -to fill said depressions, and then brushing off the surplus powdered material but allowing said material to remain in said depressions to accentuate the relief. a

4. The process of making pictorial reproductions in metal plaque form which consists in forming a base member of copper or copper alloy in embossed relief, having portions raised proportionately to the pictorial reproduction being made, and having depressions formed between said raised portions, electroplating the surface with a coating of precious metal, then spreading finely powdered carbon or lampblack upon the surface to fill said depressions, and then brushing off the surplus powdered material but allowing said material to remainin said depressions to accentuate the relief.

In testimony whereof I have signed my name to this specification.
