Abstract: 3146. Wilzin, A. March 3, 1914, [Convention date]. Blowing.-Relates to an automatic bottleblowing machine in which means for automatically filling me panson or measuring mould from below are combined with means, such as are described in Specification 20,299/13, for varying at will the duration of the parisonstretching period so as to adapt it to the varying conditions of heat and composition of the glass. The blowing-mechanism is suspended from wheels 22 running on rails 23. The mould and operating parts are mounted on a framework which can be raised and lowered relatively to the wheels. The machine is driven by an electric motor 30 which rotates the controlling- disk 43 continuously and also intermittently rotates two cam-disks 40, which actuate the moulds and blowing-devices, through a clutch 36, which is operated periodically by a dog 48 on the controlling-disk 43. The dogs 48, 50 may be moved around the disk 43 and fixed at any desirable points. The halves of the parison mould 66 are carried by pivoted arms 61, which are connected by links 63 to a reciprocating slide 65. The finishing-mould halves are pivoted on a pin 74 and are connected to the links 63. A bent lever 77 pivoted on a hollow column carries the bottoms 78, 79 that co-operate with the parison and finishing moulds respectively. The lever 77 has a short vertical reciprocation and oscillates horizontally to clear the bottom of the moulds. The neck mould 55 is carried by a slide 54 that moves horizontally and stops at three places, where it is connected to the air exhausting or blowing devices. In the exhausting position, shown in Fig. 1, glass is drawn into the parison mould, the air supply being controlled by a valve 99 operated by a dog 100 on the plunger 95, which forms the depression of the top of the parison. The halves of the parison mould 66 being opened, the neck mould and the parison are moved into the second position below a valve box 103, the valve being operated by the oscillating arm 102 that operates the plunger 95. In this position, the parison is partly blown, while the bottom mould 78, carried by the lever 77, shapes the lower part. The mould 78 is moved away, and the neck mould conveys the parison to the third position beneath the valve box 105, also operated by the arm 102, where the parison is enclosd by the finishing- mould. Here the parison stretches to its full length by its own weight and is completely blown. The valves 103, 105 may also be operated by dogs on the controlling-disk 43. After the bottle is blown, the bottom 79 is moved away from the finishing-mould, the mould then opens, and pins projecting from it engage and open the halves of the neck mould, thus allowing the finished bottle to fall into a cooling-pot 82. Finally, the cooling-pot is swung about its trunnions 82 and a knock-out pad 89 receives a blow from a lever 90 and ejects the bottle on to an incline 91 which leads to the annealing-oven. Gathering molten metal.-A supply of molten metal is lifted from the furnace into contact with the bottom of the measuring-mould 66 by means of a ladle 17, which is reciprocated vertically by means of a crank-pin on a wheel 11. The wheel is driven from a driving-shaft 2 through a clutch 6, which is thrown into operation when a catch 7 is pushed to one side by a rod 9 actuated by a dog 50 on the controlling- disk of the blowing-machine. The ladle has a hole 121 in the bottom through which the glass runs when the ladle is raised, thus preventing an accumulation in the ladle of glass that has been in contact with the mould and air. A modified form of gathering-device, shown in Fig. 7, consists of a vertical movable tube 123, the lower end of which always dips into the glass, while the upper end is lifted periodically into contact with the lower end of the mould 66. Cu.tting off excess of metal.-A cutting-blade 69, mounted on an arm 67 pivoted to one of the arms 61 of the parison mould, separates the glass in the mould from that in the ladle, and at the same time closes the bottom of the mould. With the gathering-device shown in Fig. 7, an annular chamber is formed between the bottom of the mould 66 and the upper part of the tube 123. Compressed air is allowed to enter the space 125 and separates the glass in 66 from that in the tube beneath. The drawings accompanying the Specification as open to inspection under Section 91 (3) (a) appear to show also an alternative form of gathering-device and a device for controlling the amount of glass sucked into the mould; this subject-matter does not appear in the Specification as accepted.
