Abstract: 26,262. Pierpont, F. H. Nov. 28. Blowing and moulding bottles &c. - Relates to machines of the types described in Specifications Nos. 4143, 4144, 4145, and 10,095, A.D. 1902, and more particularly to that form of machine described in Specification No. 4145, A.D. 1902, but the invention is also of general application. Fig. 1 shows a side elevation of the machine. The invention consists, firstly, of means for raising the mouth-casting nipple out of the bottle neck on the neck mould being swung back to release the bottle. For this purpose, a lever t is pivoted, at one extremity r<1>, to the sleeve upon which the mouth-casting nipple is secured, and, at its opposite extremity r<2>, to the rotating carrier-bracket c upon which the parison and neck moulds d, e are carried. An arm t<1> of the lever is provided with a pin or roller t<2> for engagement with a box cam t<3> formed upon the boss of a holder e<2> of one of the neck-mould parts, so that, upon the opening of the neck mould, the lever is tilted at the extremity r<1> and lifts the nipple out of the bottle. Secondly, of means for automatically locking and unlocking the two parts e<2>, Figs. 1 and 6, of the holder of the parison mould as the handles e<3>, e<7> are moved towards or away from each other. A lever e<21> pivoted to one part of the holder has at one end a catch e<211>, and at the other the handle e<3>, in which is a rod e<4> pressed by a spring against a stop x, the surface of which is so shaped that when the handles are moved towards each other, the catch e<211> is engaged with a projection e<22> on the other part of the holder e<2>, and when the handles are moved apart, the catch is automatically disengaged. Thirdly, of an air valve, through which air under pressure is admitted into the parison. The valve, Fig. 8, is provided with a plug u<1> mounted loosely in its barrel and provided with a recess u<3> in communication with the air supply and having mounted therein a spring u<10>, by which and the air pressure a segmental piece u<4> is pressed tightly against the barrel and prevents the passage of air until turned by the handle u<2>, Fig. 1, from the position shown. Fourthly, of means for spraying oil on to the mouth-casting nipple to cool it. The oil is contained in a reservoir v<1>, Figs. 1 and 10, which is in communication with a hole v<8> in a plunger v<5>. This plunger is pushed inwards until the hole v<8>, which is full of oil, comes into conjunction with a port v<61> in communication with the air reservoir, whereby the oil is forced out through a port v<7> down to a perforated pipe encircling the nipple. Fifthly, of screws g<2>, g<3>, Fig. 1, by which the rods g, on which are mounted the brackets carrying the finishing- moulds m, are adjusted so as to bring the moulds m to the required position. Sixthly, in making the parison and neck moulds separate from the brackets by which they are carried and in which the locking-devices are mounted, so that the mould parts may be replaced without difficulty. Seventhly, in causing the plunger q<2>, Fig. 1, to be operated by a lever q, which is placed in notches in a post k according to the operation to be performed, i.e., in the notch w<11> for casting the parison, in the notch w<111> for the plunging of the parison, and in the notch w<1> for blowing the finished bottle. Lastly, when making jars, of a mushroom head fixed upon the plunger, and an in wardlyprotruding part upon the neck-moulding ring, for the formation of the mouth of the neck of the jar.
