COUNTY on YORK, ENGLAND.
METHOD OF MANUFACTURING INLAID ARTICLES.
SPECIFICATION forming part of Letters Pate-nt No. 285,619, dated September`25, 1883.
Application tiled June 20, 1883. (No model.) Patented iniEngland Juno 2, 1880, No. 9,253, and in France October 5, 1580,
To @ZZ whom it may concern:
Be it known that I, GoD'EREY HrRsr, of Whitby, in the county of York, Englandkhave invented a new and Improved Method of Manufacturing Inlaid Articles, of which the following is a full, clear, and` exact description.
My invention relates to a new or improved method of manufacturing various inlaid articles; and it consists of producing ornamental, useful, or decorative articles by a process wherein plastic material is cast` upon and around a design or device of jet or other ma, terial.
The invention also consists of the improved inlaid article.
In practicing my process I make use of a mold of the form of article to be imitated, and also of a templet cut to receive and hold the device or design in the mold; or in place of the templet I may cut or form the design or device in the bottom of the moldwhere the material of the mold will permit, all as hereinafter described.
Reference is to be had to the accompanying drawings, forming part of this speciiication, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a perspective view of themodel of the object to be imitated. Fig. 2 is a perspective view of the templet. Fig. 3 isa perspective of a star-shaped deviceor design of Fig. 4 is a sectional elevation, showing the method of `making the mold from the model. Fig. 5 is a sectional elevation of the mold, having the templet showing both the templet and device or design placed in the mold ready to receive the plastic material. Fig. 7 is a sectional elevation of the same after the plastic material has been put or poured in the mold. Fig. S is a sectional elevation of the plastic material and design removed from the mold. Fig. 9 is a sec/Y tional elevation of the same, showing the-plastic material coated with varnish, enamel, or other surfacing. Fig. 10 is a plan view of the completed ornament, and. Fig. l1 is a sectional elevation, showing a modification.
In carrying out the invention I proceed as follows: I first take an outline model, a, in
Fig..6 is a sectional elevation,-
Iplace the design d, which may be made of 6o one or more suitably-shaped slabs or pieces of j et, (in this instance I have shown the design in starshape,) in the mold at the place pref pared in the templet or mold to receive it,
and when requisite I also place the metallic mounts usually employed in j etornament manufacture in the mold. I then fill the mold with any suitable plastic material e-such, for istance, as gypsum, or any of its preparations,
cement, caoutchouc, celluloid, or the like, col- 7o ored as may be desired-and employ the usual means to insure the proper and complete lling of the'lines and corners of the deviceor design, such as brushing, shaking, or pressing. I then allow the cast to set or harden. y
Vhen the cast is removed from the mold, the jet forming the device or design will be found to project above the surface of the plastic material e, as shown in Fig. 8, a distance equal to the thickness of the templet c of the depth of 8o the device cut in` the metal mold. This difference in level is intended to allow of a coating or a number of coats of any suitable varnish or enamel of the color required being applied to the body of the article, as shown at f, Fig. 9, S5
and when sufficiently covered I smooth and level the surface by means of sandpaper, and
finally polish with rotten stone, or with whiting.
-ticle may be electroplated. Vhen caoutchouc is employed, it is vulcanized after the lines of the design are iilled. Y
In another arrangement or modification I take a slab or piece or a number of slabs or pieces of jet, g, Fig. l1, and engrave upon it or thereon any device or design d I desire, and I ll the spaces cut out by the engraving with enamel e', caoutchouc, celluloid, or the like, of the colored desired, after which I sub roo Into this mold 55 Instead of enameling or varnishing, the ar- A9o init the article to a gentle heat, or to both heat and pressure combined, as may be requisite or necessary. After the drying, or both drying and dressing, is or are complete, I grind off any superfluous portions of the filling on an ordinary grindstone, and polish the article in the usual Way. rlhese slabs or pieces of j et so prepared may be embedded in any usual matrix and employed for ornamenting various articles; or each piecel may be used as an ornanient for personal Wear.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A method of making inlaid articles, which consists in iirst making an outline model of the article to be imitated and forming a mold thereof; secondly, covering the mold-bottom with a templet representing the intended design and the suitably-shaped slabs or pieces of 2o jet; thirdly, forming the body of the article in the mold out of plastic material; fourthly, coating said body with varnish or enamel of the desired color; and, lastly, smoothing and leveling the surface of said body, as described. 25
