A.D. 1865.
Patent Abridgment 1865 5

5. Parker, J. F., and Tanner, J. Jan. 2.

Materials. — A residue left in a retort when preparing oxygen, and consisting of a mixture of caustic soda and lime, may be used in glass-making.

Patent Abridgment 1865 12

12, Helsby, W. G. Jan. 3. [Provisional protection only.]

Stained glass. — Coloured opal glass for use in photography is obtained by coating glass sheet having a "body-colour" with a coloured opal or enamel. The surfaces are finally polished.

Patent Abridgment 1865 56

56. Bentley, B. W., and Bailey, W. H. Jan. 7.
Drawings to Specification.

Transparencies. — The Provisional Specification describes a method of forming paper &c. transparencies applicable for window decoration or lamp shades. Dies are employed in an embossing press to produce an intaglio impression in coloured or white paper &c., that can be mounted between two sheets of glass and viewed as a transparency. The dies are obtained by taking a metal casting from the plaster mould of a bichromatized gelatine photographic print.

Patent Abridgment 1865 196

196. Drevelle, A. Jan. 23. [Provisional protection only.]

Elastic supports or buffers. — The extremities, or feet, of furniture, china, glass, or pottery or similar articles may have small pieces of suitably-shaped cork, india-rubber, &c. attached to them, to deaden the sound of the impact of the article with other objects.

Patent Abridgment 1865 497

497. Webb, T. G. Feb. 22.

Blowing; pressing; moulding; ornamenting. — Ornamental glass articles are produced by combining the usual processes of blowing and pressing; for instance, in the manufacture of a wine glass or decanter, provided with an ornamental band, the latter is first pressed to shape in a mould in the usual manner, and, being held in its heated state by pincers or other supports, has inserted into it a parison of the required article, the two parts being united on completing the blowing operation. Ornamental pressed glass, such as medallions, crests &c., may also be secured in a like manner. Preferably, however, these latter are placed in recesses in a mould, into which the wine glass &c. is afterwards blown. In another application, a cup-shaped piece of pressed glass is first formed, and another part blown on to it, which part may constitute the upper portion of a wine glass or decanter.

Patent Abridgment 1865 786

786. Johnson, J. H., [Soc. B. Cresswell, A. Tavernier, and
E. Dodé], March 21. Drawings to Specification.

Ornamenting. — Looking-glasses, mirrors, &c. are made from glass which is platinized by a special preparation. A quantity of platinum foil is dissolved in a mixture of pure nitric acid and hydrochloric acid. The chloride of platinum so formed is evaporated to dryness, and is ground in a glass mortar, and is carefully mixed with essence of lavender, and, after standing for six days, is filtered twice. The filtrate, which contains the platinum in suspension, is mixed with a flux formed of German litharge and lead borate, ground together with essence of lavender. This mixture is applied to the glass by means of a brush, and the platinizing of the glass is completed by heating it in a special muffle adapted to accommodate various sized sheets of glass, and to prevent the glass from being blacked by smoke from the furnace. Instead of allowing the mixture containing the essence of lavender to settle for six days, it may be treated with hot water in a separating funnel, or by other means adapted to free the essence of lavender from free acid &c.

Patent Abridgment 1865 868

868. Williams, J. March 28.

Ornamenting. — Glass articles, especially those having a circular figure in plan, are ornamented by forming on them an annular rim b concentric with the edge of the article and presenting the appearance of an inverted corona. The rim may be left plain, or, after annealing, may be cut, perforated, or otherwise ornamented. The invention is principally applicable to articles made of flint and coloured glass, such as circular dishes, flower-stands and vases, decanters, drinking-vessels, wine glasses, lamp shades and reflectors, and salt cellars.

Patent Abridgment 1865 897

897. Baugh, B. March 30. [Provisional protection only.]

Stained glass. — Manganese oxide is added to the materials used in making glass for lamps and other reflectors, in order to give the glass a purple colour. White arsenic or arsenious acid may also be added, to give opacity. Platinum chloride solution is applied to the glass, which is heated in a muffle.

Patent Abridgment 1865 1220

1220. Emerson, A. H., and Fowler, R. May. 1. [Provisional protection only.]

Obtaining metal. — Alkaline, earthy, or common metal oxides are fused with silica, to form glass, and any well-known colouring materials may be added during the fusion. The materials are heated by a blast of air under pressure, which is gradually raised in temperature up to that of hot blasts used in blast furnaces for iron smelting. Metal obtained by re-melting soda water bottles &c. is used for casting mantelpieces, sinks, wash-hand basins, monumental and other tablets, slabs, coffins, boxes, and other hollow articles and the linings for hollow articles.

Patent Abridgment 1865 1905

1905. Chaudet, J. H. July 21.

Stained glass. — Glass is coloured by means of chromium oxide.

Patent Abridgment 1865 2233

2233. Gore, W. H. P. Aug. 30. Drawings to Specification.

Bottle necks, making. — To pierce bottle necks for cork retaining wires, after the neck is formed, the rotation of the bottle is stopped, and two pins are simultaneously forced through the neck from opposite sides.

Patent Abridgment 1865 2815

2815. Solomons, S. Nov. 1.

Transparencies. — Magic-lantern, phantasmagoria, and like transparent slides are produced by chromolithography, using transparent colours instead of the ordinary colours. An impression is taken upon a sheet of gelatine or other transparent material, which is afterwards mounted upon or between sheets of glass in a frame; or, an impression is transferred to glass and varnished.

Patent Abridgment 1865 3092

3092. Wright, A. J. Dec. 2.

Transparencies. — To apply photographs to glass they are first varnished with Canadian balsam, thinned with turpentine or the like, then attached to the glass by a solution of gum arabic, and, lastly, varnished on the back until sufficiently transparent. If the paper is to be removed, the varnish is washed off with turpentine, and the paper carefully detached by fine glass paper and, finally, by a sponge or silk pad and water. The picture may then be coloured and finished with a coat of varnish. Another method consists in soaking the picture in the varnish previous to affixing it to the glass. Tinted glass may be used.

Patent Abridgment 1865 3325

3325. Newton, W. E., [Wurtz, H.]. Dec. 23.

Transparencies — for lamp and gas shades, lanterns, or reflectors, are made from substances which are produced by heating together aqueous solutions of glue or gelatine, and chromic acid or an alkaline bichromate, and allowing the liquid to gelatinize. Before this treatment, the glue or gelatine solutions may be mixed with heavy powders to give weight to the product, with sand, clay, emery, glass, red oxide of iron, or Tripoli powder to give hardness, or with chopped fibre, such as cotton, hair, spun glass, asbestos, or the like to give strength and toughness. Suitable colouring-matters may be added. Thin sheets are prevented from becoming brittle in dry or cold atmospheres by rubbing them with glycerine, which becomes absorbed by the sheets. Greasy or resinous powders are moistened with dilute alcohol before being added. Alcoholic solutions of castor on other oil, shellac, gum mastic, or the yellow resin of gamboge may be added. In making small articles, the jelly is cast in an elongated cylinder roller in tissue paper, and then enclosed in an elastic network bag, which causes it to keep its shape in drying. The bag may be inelastic, and be weighted. The articles are turned from the cylinders so formed. Masses for making large objects are built up by uniting several layers of material. The dried layers are pressed together by sheets of wire gauze. The composition may be cast in large moulds, and then sliced into sheets, which are dried partially on oily metal plates. When no longer adhesive, the sheets are dried completely between layers of wire gauze.
