Abstract: 3122. Vernay, J. B. Feb. 13. Blowing and moulding bottles &c.-Relates to a machine for simultaneously making four bottles. The main features of the invention are as follows : -(1) Placing the molten metal in a vessel which is independent of the machine, but which is placed in a support attached thereto, the molten metal being injected by air pressure into the neck moulds. (2) The neck and ring moulds are not inverted. (3) The initial hollowing of the glass is caused by the insertion of a rod, not by blowing. (3) The parison mould is fitted with movable shoulders to allow the collar to be made of any required size. (4) The bottle is finished in two moulds, which are successively employed. (5) Special moulds &c. for softening the glass, forming inscriptions and ornaments on the bottles, and detaching the bottle from the neck rod. (6) Apparatus for conveying the bottles to the annealing-furnace. (7) Arrangements for supplying the air for Mowing. Fig. 1 shows in elevation, and Fig. 6 in plan, a general view of the apparatus. A central standard carries a four-armed crosshead 90, which is capable of being raised and lowered and is also movable in successive steps of 90‹ so as to bring the glass under the operation of four sets of moulds. The operation of the machine is as follows :-The receiving- mould 1, having been filled with molten metal, is placed in the support 4, the crosshead 90 is then lowered, and the two pairs of divided neck moulds, enclosed in the casing 129, are brought down to the mould 1. The moulds are automatically closed, a rod descends into the glass, and air is admitted through the pipe 9 so as to force the metal into the neck moulds. The crosshead then rises and turns through 90‹, bringing the glass above the parison mould enclosed in the casing 224. Meantime, the lower parts of the neck mould have opened. The crosshead then descends, and the glass enters the parison mould, which is formed with a separate upper part. The parison mould is closed and rotated, a blow tube enters the glass, and air is admitted. The crosshead again rises, and carries the parison over the finishing-moulds &c., into which it is lowered. The finishing- moulds consist of two pairs of half moulds 250, 251 and 254, 255, arranged at right-angles, in which the bottle is successively shaped by blowing. The moulds and their bottoms are independently rotated during the operation, and a punch raised from below forms the depression in the base of the bottle. The next movement of the crosshsad carries the shaped bottle to a re-heating mould 373, 374, fitted with suitable gas burners, which re-heat the neck so as to separate it from the rod and also soften the part of the bottle to be imprinted with ornaments &c. There-heating mould is then opened and withdrawn, its position being taken by the inscription mould 375, 376, and air is supplied to cause the bottle to take the inscription. Finally, the mould opens, the base supporting the bottle is tilted, and the bottle falls upon a carrier band 446, by which it is conveyed to the annealing-furnace. Four bottles are simultaneously in process of manufacture, one being held by each of the sets of neck moulds 129, 130, 131, &c. on the respective arms of the crosshead, the bottles being thus in successive stages of formation. The various parts of the machine are automatically operated from the main shaft 206 carrying the driving- pulley 207.
