Abstract: 12,924. Haley, J. June 25. Blowing and moulding bottles &c.-Relates to presses for making bottles, jais, &c. Fig. 4 shows a front view of one press, several of which may be arranged side by side on the same machine, and Fig. 3 shows a plan of the table of a machine with three presses. The table 1 carries vertical standards 5, on which slide crossheads 6, these crosshaads being reciprocated by connecting rods 8 actuated by cranks on an axis driven by compressed air, or steam engines fixed to the base of the machine. Each crosshead 6 carries an adjustable threaded tube 32, on which is mounted a second crosshead 35, in which slide rods 46 carrying a plunger, which is also connected to a rod 41 passing axially through the tube 32 and acting against a spring 43 above, the tension of which can be regulated by a screw 39. The neck mould 100 is supported by rods 48 sliding in the crosshead 35. A rim mould 50 is similarly supported by rods fitted with springs 52 and sliding through a collar 54 fixed to the tube 32. The neck-mould is made in sliding sections, which can be separated by turning a plate provided with slots engaging pins in the sections. All the crossheads &c. are slotted, where necessary, to allow the rods 8 to work freely. The table 1 is fitted with guides to receive sliding plates 66 actuated by hand. Each plate has a recess 69 to receive the parison mould 70, and a pair of hinged carriers 76 for the blowing-mould, these carriers working on a plate 73 fitted in a circular opening in the slide and resting on a table supported by a counterweight. The carriers have pins engaging slots 74 in the plate 73 and diverging slots 65 in the table &c. The air for blowing is supplied through a disc carried by a pivoted arm, which is swung into position at the required time by the movement of the slide 66. The mechanism for each press can be put in action by a lever, and is automatically disconnected when the plunger has descended and returned to its raised position. The operation of the machine is as follows :-A suitable quantity of glass having been placed in a mould 70 in position on the slide 66, the slide is pushed back to bring the mould under the plunger, the machine is then started, the plunger descends, bringing the neck-mould and rim mould down on to the mould 70, and the further descent of the plunger moulds the parison. The plunger then rises out of the mould, and carries up the neck and rim moulds, the latter having the parison suspended from it. The slide 66 is drawn forward so as to bring the blow-mould, which is placed on the carriers 76 into position, the action of the slots 65 causing the closing of the mould. Simultaneously an arm (not shown) is revolved, and brings a disc having a conduit connected with the compressed-air supply above the neck of the parison, the supply being cut off by a valve in this disc. The descent of the plunger opens the valve so as to blow the bottle &c., the plate 73 carrying the mould being depressed below the level of the table against the action of the counterweight. On the rise of the plunger, the parts are brought up again, and the neck mould is opened and the slide is pushed back, leaving the completed article standing in the opened mould.
