Title: Improvements in methods of making glass vessels with neck from a tube
IPC: C03B23/11
Filed: 1927-04-01
Abstract: 274,765. Meyer, F. April 1, 1927. Forming articles from tubular blanks.-A method of making a glass vessel with a tapered extension, such as a vial or ampoule with a pointed neck, consists in forming a bottom on the end of a glass tube and then pushing out the bottom, while the glass is still hot, by means of a tool inserted in the tube. A tubular blank is heated at the middle by means of a blowpipe and is divided into two shorter tubes a<1>, a<2>, Fig. 3, on which a bottom is formed. A tool b<1> with a conical point is inserted in each tube and the hot glass at the bottom is pushed out to form a pointed extension c, Fig. 4. The ends of the necks are opened and the two tubes are reversed and fused together at their open ends, as shown in Fig 5. The tube may then be divided again at the join and formed into two vials having flat bottoms, as shown in Fig. 6. Instead of fusing the two tubes together, the open ends may be heated, drawn-off, and then flattened out by means of a suitable tool. If the neck is to have a constriction to facilitate opening, it is formed with a tool g<2>, Fig. 12, having a wide point. This tool is then replaced by one having a finer point, as shown in Fig. 14, and the glass is softened and allowed to collapse and form a constriction i. A tube may be constricted at any part of its length by closing one end with a stopper k‹, Fig. 16, heating the part of the tube to be constricted, and then inserting a rod and pressing it against the stopper so that the heated part of the tube stretches and becomes narrower. Instead of using the stopper k‹, the end of the tube may be closed and afterwards cracked-off. The tools may be of skeleton formation, or they may be made hollow and provided with slits or recesses, in order to prevent them from chilling the glass and thereby producing strains which may result in breakage.
