Abstract: 7050. Hilde, H., and K§gler, E. March 23. Blowing; moulding.- Two divided multiple moulds b, b<1>, one of which is shown in section in Fig. 12, are mounted on the ends of square slides g, g', which pass through holes in a rotatable block h and are connected by a rope k passing over a pulley i. The mould halves are carried by sliding frames 35, 36, which are connected by short levers 37 pivoted at 38 to the slides g, g', so that the frames 35, 36 move in opposite directions. To close the mould, a cam 40 is rotated by hand to the position shown on the left of Fig. 2 and moves the frames 35, 36 in opposite directions. The molten metal is poured into the upper chamber 45, Fig. 12, of the mould b, and is then blown into the lower chamber 45<1> by compressed air from a nozzle t, which is brought down by the compressed-air gear shown in the ordinary way. In descending, the rods s, Fig. 1, to which the nozzle t is attached, carry with them a rack x, which being supported by loose links w, moves over the teeth of an adjacent wheel z without causing rotation. The nozzle t is then raised and carries with it the rack x, which engages the wheel z, causing it to rotate and actuate a rope r<11> passing over a pulley on the same shaft with the wheel z. The rope r<11> also passes round a pulley r on the block h and, by rotating it, swings the mould b over on to the other side of the machine table T and under another nozzle t'. The mould b<1> is at the same time swung to the left side of the machine, the table being cut away at the back to allow of this. The nozzle t<1> is then brought down, after the neck of the blank has been enclosed by a mould f, and in its descent brings down a rack 5 engaging a pinion 6, which, through the rope gearing 14, 17, 18, 19 and pinion q, moves a rack o towards the back of the machine. A projection n on the rack o engages a catch m on the slide g'. The ware is then blown by compressed air from the nozzle t<1>, which is then raised, carrying with it the rack 5 and a rack 23 similar to the rack x. The pinion 25, engaging the rack 23, is thus rotated and, by means of the rope gearing 27, 30 and the bevel-gear 32, rotates a short lever 34 in a counter clockwise direction. The lever 34 strikes a lever 44, with which the cam 40 is connected by a link 41, and moves it and the frame 36 to the position shown in Fig. 10, thus opening the mould b. The upward movement of the rack 5 draws the rack o to its former position and, by reason of the engagement of the catch m with the projection n, draws the mould b<1> under the nozzle t. The glass articles are removed from the open mould b and taken to the finishing-moulds where the blowing is completed as usual. The above cycle of operations is then repeated. Forming vessels of standard capacity.-In order to insure that the same quantity of glass is used in the formation of vessels of this kind, a slide 47, Figs. 15 and 16, is inserted between the chambers 45, 45<1> of the moulds. By moving the slide 47, the metal in the chamber 45<1> is cut off from the excess remaining in the chamber 45. This may be repeated after blowing. The two halves of the slide 47 are formed with inclines 51, which engage with rollers 52 at the end of the stroke and press the two parts into close contact. The two parts are connected by dowel pins 49.
