Patent Abridgment 1856 242  

242. Chance, K. Jan. 29.

Materials; moulding; firing. — Articles are moulded from pulverized vitreous matter, such as collet or waste glass, with or without the addition of sand or other suitable material. The pulverized material is mixed with water to enable it to hold together, and the mass is then pressed into a mould of the required shape. When released from the mould, the moulded article is carefully dried in a suitable kiln at a low temperature, and, when dry, is immersed in and covered over with sand, to regulate the heat and to support any parts which might give way during burning. The temperature of the kiln is then raised gradually, until the material is partially fused or agglomerated into a compact mass.

283. Chance, J. T. Feb. 1.

Flattening. — Consists in the employment of rollers, in place of wheels, for the beds, to diminish the space occupied by the framework and wheels. The flattening bed rests on two bars a, a, which are carried by flanged rollers r, r rolling on fixed rails b, b. The rollers are kept in their correct position by means of axles c, c and a framework f, f resting upon them with suitable bearings.

Patent Abridgment 1856 580  

580. Chablin, L., and Hennique, A. March 10.

[Provisional protection only.]

Ornamenting. — A glass article is ornamented by painting a design with a pasty mixture of silver chloride and spirits of turpentine, heating the article to a red heat, surrounding it, when cold, with copper wire, and finally depositing silver or gold upon it from an electroplating solution.

Patent Abridgment 1856 609  

609. Rees, G. March 13.

Ornamenting; moulding; rolling; printing.— Ornamental designs, patterns, or inscriptions in relief or intaglio are produced by heating plain, coloured, or ornamental sheets of glass, and pressing them between dies or rollers formed with the desired patterns. The plates are afterwards annealed. Portions of the raised patterns may be removed by grinding, and the backs of the sheets may be ornamented by gilding, silvering, enamelling, painting, staining, &c. The glass thus treated is used for windows or for decorative purposes.
Patent Abridgment 1856 823  

823. Blake, O. April 5.

[Provisional protection only.]

Moulding. — In the manufacture of plate glass, the fused metal is poured from the pot upon a casting table, the sheet being removed while in its soft state into an annealing-kiln ; other sheets are cast in a similar manner until the pot is empty, or until the whole of the metal in pots in a furnace has been used up.
Patent Abridgment 1856 1171  

1171. Cornides, L. May 17.

Transparencies. — Textile and wire-woven fabrics for window blinds, and other transparent decorations, are ornamented by transferring designs printed by lithographic or other means. The print, on transfer paper, is coated with a solution of gelatine, or of gelatine and sugar, in water; and when this has set to a jelly, the print is placed on the textile or wire fabric. After drying, the paper is wetted with a solution of acetate of alumina or with water, and the paper detached. Any parts of the gelatine may be removed by softening with warm water. In place of the above, an elastic medium, prepared as described in Specifications No. 2066, A.D. 1854, and No. 2112, A.D. 1855, may be applied to the fabric and fixed by means of gelatine, as above, or by any other suitable transparent cement. The ornamented surface may be protected by coating with collodion or other transparent varnish.
Patent Abridgment 1856 1204  

1204. Medlock, H. May 21.

[Provisional protection only.]

Materials. — Glass, enamels, and other vitrefied substances are made by fusing a clay, containing from two to ten per cent. of potash or soda, with such a proportion of sand and lime, or carbonate of lime, as will produce with the constituents of the clay definite chemical compounds known as double silicates. For the purpose of reducing contained iron to the lowest oxide, and so improving the colour of the product, black marble, the colour of which is produced by carbon, is substituted for the lime or carbonate of lime. Metallic oxides or ores may be added to produce the required colour and opacity of enamels &c.
Patent Abridgment 1856 1413  

1413. Wright, W. June 14.

[Provisional protection only.]

Moulding bottles &c. — Decanters, cruets, water jugs, cream jugs, &c. are moulded by a plunger which forms the body and neck, the former being open at the bottom. The bottom of the vessel is moulded in a separate piece, and is united to the body while both parts are still pliable.
Patent Abridgment 1856 1515  

1515. Johnson, J. H., [Tassy de Montluc, E. P. T., and Gauthier, L. J.]. June 27.

Materials. — Consists in using barium carbonate, obtained by decomposing barium sulphide in aqueous solution with carbon dioxide in the presence of potash, soda, or other alkali, in the manufacture of glass and crystal, the compound partially or wholly replacing sodium or potassium carbonates in the production of silicates.
Patent Abridgment 1856 1813  

1813. Chamblant, P. M. J. July 31.

Obtaining metal. — Molten glass is mixed and treated by forcing air or gas through it whilst in the melting-pot, by means of a platinum tube B, C, fitted with a rose A and connected by a flexible tube with a compression pump. When air is used, it causes the oxidation of excess of carbon &c, whilst hydrogen, carbonic oxide, &c. cause the reduction of sulphates, phosphates, and other substances. Steam may be used to decompose or volatilize chlorides present in the glass in injurious proportions.

2192. Cooper, W. H. Sept. 18.

[Provisional protection only.]

Cutting glass. — Windows, frames, panelled work and the like glazed with stained, plate, or other glass are formed with each colour in one piece cut out by drilling holes at the corners and completing the design by means of a diamond, with or without fluoric acid.
Patent Abridgment 1856 2344  

2344. Wilkinson, W. Oct. 7. Drawings to Specification.

Moulding. — Hollows or apertures in glass wheels or bowls for castors or other articles may be formed by means of a hollow tool designed to press out or form the required aperture.
Patent Abridgment 1856 2345  

2345. Wilkinson, W. Oct. 7.

Transparencies; transparent and translucent materials. — Transparencies are made by inserting designs, pictures, prints, wax flowers, imitation animals, lace or other textile fabrics, perforated metal or wire gauze, or plaster, alabaster, gutta-percha, metal, or other devices between two glass sheets. An engraving, print, &c. on paper may be first rendered transparent by soaking in oil or oleaginous matter, drying, and immersing in turpentine or spirit. The prepared paper is then cemented to one glass sheet, and tape or the like is cemented to the edge of the glass sheet, after which the two glass sheets are secured together by india-rubber, gutta-percha, or a metal clamp or frame, or by melting the edges. A glass case containing water may be attached to one glass sheet, or may be formed in one therewith. When coloured engravings or prints are employed, spirit wash is applied to the glass sheet, and a drying spirit is brushed over the engraving, after which the engraving is placed on the glass sheet, and a mixture of oil and spirit is applied to the back of the engraving until the design is seen. The oil and spirit are then wiped off, and the second glass sheet is fixed in position.
Patent Abridgment 1856 2931  

2931. Green, J. Dec. 11.

Attaching glass to metal. — Relates to the manufacture of lights for walls, street vaults and other buildings, of deck-lights for ships, and of bearings for heavy machinery, by casting molten glass into metal frames. The frame, heated to dull redness, is placed on a casting plate x, and molten glass is gathered or ladled out of the furnace pots p by means of the ladle j and put into the frame, after which it is transferred to the annealing-kiln. The ladle is suspended by a chain or rod r from a flanged pulley m adapted to run on a bar u, which is suspended by a pivot pin v and two hangers h. The hangers have hooked upper ends u, which slide on transverse slightly-curved bars in the roof, so that, by moving the bar n about the pivot pin v. the ladle can be brought opposite any one of the pots p.

3074. Clark, W., [a communication]. Dec. 26.

Transparent materials. — Fabrics of thin cotton, flax, or silk, after treatment in successive baths of gelatine and tannin, or the like, are rendered transparent by linseed oil, and may be used for window blinds.
