Abstract: 10,828. Philippoteaux, A. May 12. Blowing and moulding bottles &c.-The parison mould s is made in two halves mounted on two arms q, which are pivoted in the socket m carried by the vertical post g, this post also carrying the revoluble table l and being vertically adjustable in the standard a of the machine. The table l carries at each end a mechanism 2 for conveying the parison to the finishing-mould 60, these mechanisms being used alternately, so that one is being cooled while the other is in use. Each conveyer 2 is mounted on lateral trunnions, one of which is provided with a hand-wheel, for the purpose of turning it from the upright to a horizontal, and then to an inverted, position, the extreme movements being limited by stops. The frame of this conveyer is provided with a tubular spindle 10, Fig. 10, terminating in a socket 11 and a neck, collar, or dish 12, the mandrel 18, which is connected at 19 to a suitable blowing arrangement, extending through the spindle 10, as shown. The halves of the parison mould s fit round the collar 12, when closed by means of their handles v, and are secured in that position by a latch x. When the latch is lifted, the halves of the mould are separated automatically by the springs 80. When the glass has been collected in the closed mould, the mandrel 18 is pushed upwards by the lever 20 actuated by the rod 22 to shape the interior of the neck, and to press the glass outwards against the mould, after which, by the aid of the blowing arrangement, the parison is perforated. The upward movement of the mandrel causes the gripping-pins 26, Fig. 10, to be projected into the neck, to hold the parison while it is being conveyed to, and formed in, the finishing-mould. The pins 26 are carried by slides 36 actuated by the inclined arms 39 coupled to the mandrel. In the modification shown in Fig. 11, the pins are carried by slides 25, having screws 27, which project into cam slots in the ring 29, this ring being partially rotated, to project the pins, by the movable piece 33, 32 actuated by the stud 30 on the mandrel. When the parison mould is opened, the counterweighted block 57, which is pivoted by means of its arms 56 at 55 on the conveyer 2, is moved up to the parison by the latch lever 58, after which the conveyer and block 57 are turned down into a horizontal position, in which the parison is rotated and elongated, by the hand-crank 17 acting through the gearing 81, 82 on the spindle 10, while it is being blown to form. The conveyer and block are then turned into an inverted position. During this movement, the latch 58 is disengaged from the cross-bar 49 of the arms 56, and the block 57 swings away from the parison, leaving the latter suspended from the pins 26 &c., between the separated halves of the finishing-mould 60, which are mounted to slide in the table 84. The finishing-mould is then closed round the parison by the bell-crank levers 67 actuated by the treadle 70, the bottom mould 61 is raised by the lever 71 to support the bottle during its elongation, and the necessary air is admitted through the mandrel 18, while the spindle 10 is again rotated. The hollow or kick in the bottom of the bottle is formed by the plunger 62, actuated by the pedal 77. When the bottle is finished, the mandrel 18 is withdrawn, and retracts the pins 26, after which the halves of the mould 60 are allowed to separate under the action of counterweights, and the spindle 10 is raised by the rack mechanism shown in Fig. 10, or by a fork engaging in the recess 42, Fig. 11, to disengage it from the neck of the bottle.
