Abstract: 6012. Koenig, C. J. March 12. Blowing and moulding bottles; removing articles from moulds; gathering metal; shearing. - Relates to that type of apparatus for producing glass hollowware in which molten glass is sucked up into parison moulds and subsequently blown to the final shape in finisbing- moulds. The finished articles are then automatically removed from the moulds. Six arms 24, Figs. 6 and 6<a>, are fixed to a collar 6, which is rotated intermittently about a central column 4 by gearing driven from a central shaft 110. A frame F is arranged to slide vertically on the end of each of the arms 24, and is formed with a rack 166 which engages a toothed wheel fixed on a shaft 180<b>, mounted on the head 24. A toothed wheel 180<c>, also fast on the shaft 180<b>, engages a screw 180<a> driven through a clutch 90 from a shaft 89, which receives motion from the shaft 110 through a reversing clutch 102 and the gear 108, 109. The clutches 90, 102 are controlled by a lever 94 and a spring rod 98, respectively, both being operated by cams on the column 4. A vertical shaft 38, mounted in the frame F, is driven from the shaft 89 by bevel-gear 60 and the universal joints shown. The parison-mould halves 143, arranged to form three blanks simultaneously, and the finishing-mould halves 142 are hinged to a plate 150 carried by the frame F, and are opened and closed by the vertical movement of bars 46, 44 the middle parts of which engage a screw 36. At the beginning of the operation, the frame F is lowered by the action of the gear described on the rack 166 until the parison-mould dips into the metal in the working-tank. A port at the head of the column 4, at the same time, places the vacuum pipe 181 in communication with a pipe 25 which is connected by passages 147, Fig. 8, with ports 148 in the neck rods U. The molten metal is thus drawn up into the moulds, the neck rods being rotated meanwhile by gearing 144. The gear is then reversed by the clutch 102 and the frame F rises to its normal position. A knife 16 is swung round by cam mechanism in the ,base of the machine and cuts off the excess of metal. The screw 36 is set in motion by clutchcontrolledgear; the lower portion 36<b> being right-handed lowers the bar 44 and closes the finishing - moulds 142, while the upper part 36<a> being lefthanded raises the bar 46 and opens the parison-moulds 143. While the moulds are both open, the plate K, Figs. 7 and 8, which supports the triple neck mould 0, is turned through ninety degrees by gearing on a shaft 55. The finishing-moulds 142 close round the suspended parisons, which are then blown by air admitted through the pipe 25 from a port in the column 4 communicating with a compressed-air pipe 183. The gearing is then reversed by the clutch 102, and the finishing-moulds open. While the finishing-moulds and parison moulds are both open, a table 133, Fig. 6<a> mounted on links 134, 135, is raised automatically to receive the finished bottles &c., and the two halves O, Figs. 6 and 7, of the neck mould are separated by a cam L which is rotated by a spur-wheel 130 on the end of a flexible shaft 129, Figs. 7 and 6<a>. The table 133 then descends with the finished ware which is removed to the leer. The parison moulds close completely, and the above series of operations is repeated during each succeeding revolution of the arms 24.
