Patent Abridgment 1858 413

413. Newton, A.V., [Le Chatelier, —.]. March 2.

Materials, — In a method primarily for making hydrofluosilicic acid, a mixture of fluor-spar with felspathic rock containing much silica and alkalies is fused in a blast cupola furnace, or the like. The resulting dross has more or less the com­position of common glasses, and may be added to the elementary materials for glass making, or used for blowing glass articles. A method of obtain­ing pure silica, suitable for the manufacture of glass &c, consists in passing carbonic acid through a solution of potassium or sodium silicate. The precipitated silica is collected and washed.

Bottle necks, making; moulding; pressing. — A pair of dies is used to form the lips or rims on the ends of the necks, one of the dies being fixed and the other movable. A ram or presser is fitted to slide in the dies, and on its end is a cone suitable for entering into the neck, and for pressing the plastic metal outwards at the same time that the end of the ram is forcing back the glass at the end of the neck. The ram and the movable die are operated by a lever handle, on the axis of which are two arms, one of which is arranged to act on a lever connected to the movable die by links or straps, so as to close the dies, and then the other arm comes into action on the ram.

Moulding. — Relates to the manufacture of glass finger plates, projecting letters and numerals, rosettes, picture frames, ornamental slabs, escutcheons for keyholes, and the like. Fig. 1 is a plan, and Fig. 2 a vertical section, of the machinery used for finger plates. An iron or brass mould is formed in four sections a, b, c, d, jointed at a1, b1, c1 and forming a space e. Designs for finger plates are engraved at f, g, h, i, and the mould can be opened by the handles k, l, held in position by a catch m turning on a joint at m1 and secured by a screw m2. When closed, the mould is lowered by turning the handle x on the axis w which operates the cam v, Fig. 2, the conical end of the mould entering a recess in the bed-plate n. The top of the mould is partially closed by the plate o turning about a joint p and operated by a handle q, the top being held down by a tooth on the lever r. A series of screws t with conical ends project through the moulds to an extent regulated by plates u of different sizes, and form countersunk holes in the finger plates. Melted glass is forced by a plunger into the moulds, forming a four-sided vessel on each of which is a finger plate in relief. This vessel is removed from the mould, and is fire polished, being supported by attachment to a square disc of glass at the end of a pontil, or, if thin, by an iron plug at the end of a pontil fitting the interior of the vessel. The vessel is annealed, and the finger plates are cut from it, ground, and polished. The vessel on which the plates are moulded may have more than four sides, and each may have any design on it.

Obtaining metal. — Powdered sulphate of barytes, silica, or fine sand, and muriate of soda are calcined together at a strong red heat, until they become a dry powder. The compound thus formed, with the addition of the proper proportion of lime, is then converted into glass. If the glass is required to be colourless, the sulphate of barytes and sand are first purified with acid.

Transparencies. - In the ornamentation of glass with perforated plates of metal &c., for use as window screens, blinds &c, a perforated sheet of zinc, paper, cardboard, gelatine, fabric, or other suitable material is covered on one or both sides with a coat of paint, and over this coating, when dry, a design is applied by block printing, transferring, &c. The design may be produced by block printing in one or more colours, so as to imitate lacework, chintz, &c. The plate so prepared is cut into pieces of any size required, and each piece is mounted for use between two sheets of window glass or plate glass, which are secured together around the edges by strips of paper or fabric and a suitable adhesive. An ornamental border and centre may be applied to the inner surface of one or both glass sheets, or to the perforated plate; or, a design may be printed in gold size, &c. on paper, and transferred to the glass or perforated plate, the transfer being covered with gold and silver leaf, and finished in the usual manner. A coat of arms, name, or professional or business notice &c. may be emblazoned, painted, or printed on the glass or perforated plate, for use in the centre or other pane or panes of the window as a sign &c. For interior use, the perforated plates may be made of gelatine, of such a nature that they will not soften or melt with the heat of the sun.

1946. Newton, W. E., [a communication]. Aug. 27.

Delivering molten metal. — The fused material is run off through orifices at the lower parts of the ovens, pots, or vessels containing it. Stoppers for these orifices are formed of earthy materials, or of hollow metal. Each hollow metal stopper is provided with a hollow handle, through which water is caused to flow, the water being run off through a small pipe, communicating with the interior of the stopper, so as to prevent the stopper from being injured by the fused materials.

2065. Page, H. Sept. 11.

Finishing. — Relates to the manufacture of crown glass without the “bullion” or large bulging piece which usually occurs in its manufacture. A hollow tube, formed with a perforated flat nose which is covered with mica, talc, asbestos &c, is connected by a flexible pipe to an air-exhausting apparatus. A stop-cock is placed in the tube. After the glass has been blown to the usual shape, the workman opens the valve between the tube and the pump, and presents the perforated nose to the glass, which becomes attached thereto. The glass is then flashed in the usual way, and when finished is released from the tube, by closing the valve.

Transparencies. — Relates to a process of transfer-printing and ornamenting on glass or other transparent substance, by which the figures or characters are better developed. A composition of boiled linseed oil and lampblack, or other colouring-ingredient, is transferred on to the glass &c, and then a coating of enamel, cement, or other hardening-material is applied.

Finishing. — Sulphuric acid is applied to metal-working tools, when they are used for operating upon vitreous substances in the manufacture of glass and other vitreous vessels.
Patent Abridgment 1858 2967

2967. Warren, T. Dec. 28.

Blowing; shaping. — Relates to the manufacture of black and similar bottles. The bottle having been blown and saucered in the ordinary way, is wetted off upon a pontil, which is fitted in a case or socket, and caused to revolve by suitable gearing during the formation of the mouth. The mouth is formed by a pair of shears carried by a stand placed near the apparatus carrying the pontil. The lip or ring of the mouth is formed of additional metal taken from a small supplemental furnace at the side of the apparatus. “To avoid the irregularity attending the ordinary “method of ‘wetting off’ the water is made to “issue upwards under a slight pressure from a “semi-circular mouth, and the bottle is laid so as to expose its neck to the issuing water, the rotation imparted to it causing application of the water equally all round the neck.”
