Title: Improvements in the parison forming mechanism of a bottle making machine
IPC: C03B9/36
Filed: 1919-11-10
Abstract: 145,336. Berger, T. Nov. 10, 1919. Blowing.-Relates to the pump mechanism of a bottle-making machine of the type in which the metal is sucked down into the parison mould by a hand-operated pump which also serves to blow up the parison. The pump cylinder 1, Fig. 1, is secured below the mould of the machine, and its piston is moved by means of a hand lever 35. The pump communicates by a pipe 21 with an airspace 49 in a casing 20 which enclose the rod 16 of the plunger 17 that forms the mouth of the bottle. The rod 16 slides through a gland 18 which is connected to the casing 20 by means of a bayonet joint in order that it may be detached easily when splinters, of glass have to be removed. This rod is connected to a pivoted arm 11 which is drawn upwards by a spring 9 to a point controlled by a screw 7. The rod 29, Fig. 2, of the piston 28 slides through a cross-piece 46 upheld by springs 43 surrounding guidte-rods 41, 45 secured to the cross-piece. The rod 41 operates a. piston valve 39 controlling the admission of air above the piston. A shaft 5, journaled in a bracket 27 in the cylinder 1, carries an elbow lever 6<1> the lower end of which rests on a bracket 31 secured to the lower end of the piston-rod. An arm 6, secured to the shaft 5, has a recess 48 which can engage the arm 11. In use, metal is dropped into the parison mould 23, Fig. 1, and the pump operated to suck the metal down into the ring mould around the plunger 17. At a point in the downward movement of the piston, a nut 38, Fig. 2, screwed on to the piston rod 29 strikes the cross-piece 46 and moves it backwards, thus opening the valve 39 to admit air above the piston. The rod 41 also moves the lever 11 and withdraws the plunger 17 from the parison, the lever 11 being finally engaged and retained by the arm 6. A reversal of the movement of pump lever moves the piston upwards and closes the valve 39 so that the piston forces air into the parison. The bracket 31 finally moves the arms 6<1>, 6 so that the lever 11 is released and the plunger 17 and restored by the spring 9 to its normal position.
