METHOD OF PRODUb'ING ART-PLAQUES.
Specification of Letters Patent.
Application filed May 27, 1911.
Serial No. 629,775.
To all whom it may concern I Be itknown that I, CHARLES O. HEN- RI UEs, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Method of Producing Art-Plaques, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved method of producing art plaques having a colored picture incorporated in the face of a body of plastic material without the use of a sheet of paper or other carrying medium, thus insuring the production of a highly artistic effect.
In order to produce the desired result, a colored picture on a carrying medium is placed on. the bottom of a mold, and then the carrying medium is floated ofl, after which plastic material, such as plaster of Paris, is poured into the mold and onto the picture, to be embedded in the surface of the plastic material.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a sectional side elevation of the mold. with the picture, its carrying medium, blotting paper, and a weighted plate in position thereon; Fig. 2 is a sectional side elevation of the mold and showing the manner of floating off the carrying medium from the picture; Fig. 3 is a like view of the mold, showing the plaster of Paris poured into the mold and onto the picture; Fig. 4 is a face view of the art plaque; and Fig. 5 is an enlarged cross section of the same on the line 55 of Fig. 1.
In order to produce the art plaque, use is made of a mold A, of silver or other suitable material, and of oval or other shape, according to the shape to be given to the plaque. The bottom of the mold A is provided with a layer B of transparent cream or grease, preferably tallow and a vegetable compound, and on this layer B is placed face down a decalcomania picture, comprising a colored picture C and a sheet of paper C or other carrying medium. The decalcomania picture is rolled down hard in the mold so as to smooth out the picture to the fullest extent, and then saturated blotting paper D is placed on top of the decalcomania picture,to saturate the carrying medium C, use being also made of a heavy plate E resting on top of the blotting paper D to insure saturation of the carrying medium without danger of wrinkling. After the carrying medium 0 is saturated, the weighted plate E and the blotting paper D are removed from the mold A, and then the latter is partly filled with water (see Fig. 2), to allow the carrying medium C to finally float ofl the picture C without disturbing the latter on the bottom of the mold A. The carrying medium C after being floated off is removed from the mold A, and the water is also poured off, and then plaster of Paris F in plastic state is poured into the mold onto the top of the picture C so that the latter is embedded in the under side of the plaster of Paris. After the plaster of Paris has set, say for an hour or so, then the bottom of the mold A is heated over a suitable flame, to melt the layer of cream or grease B and thus allow convenient removal of the plaque from the mold A on turning the latter upside down. It is understood that when the mold A is heated, the layer B of grease or cream melts and thus prevents the colored picture C from adhering to the bottom of the mold.
By making the art plaque in the manner described, the colored particles forming the picture G are not disturbed in their proper relation and are embedded in the face of the plastic material F without the use of the carrying medium, and hence the particles Patented Jan. 9, 1912.
forming the colored picture C are not liable to peel off as they are securely bound in place in the plastic material.
Art plaques produced in the manner described and shown, can be readily used for decorating or advertising purposes, especially as such art plaques can be cheaply manufactured.
'Having thus described my invention, I claim as.new and desire to secure by Letters Patent:
The herein described method of producing art plaques, consisting in applying a layer of grease to the bottom of a mold, then placing a decalcomania picture face down on the said layer of grease, then smoothing the said picture and saturating the carrying medium of the picture while under pressure, then floating off the carrying medium, and leaving the color forming the picture undisturbed in position in the mold, then pouring a plastic material into In testimony whereof I have signed my the mold and onto the top of the colored name to this specification in the presence of 10 picture to embeld tge latter in the face of the two subscribing witnesses.
astic materia t en allowin the latterto set, then heating the mold to r elt the grease CHARLES HENRIQUES' and then removing the plastic material with Witnesses: the colored picture embedded therein from THEO. G. Hos'rER, the mold. PHILIP D. RoLLHAUs.
