Abstract: 17,889. Brearley, B. J. Aug. 18. Annealing; blowing and moulding bottles; bottle necks, making.- Apparatus for blowing and moulding bottles with either plain or threaded necks, and for annealing the finished articles, is shown in Fig. 1. On a tubular spindle is mounted, so as to rotate, a frame A which is provided on either side with parison moulds F, neck moulds D<1>, and core rods D. The parison moulds are lined as at F<4>, Fig. 6, and made in two halves, each of which is mounted on supporting-arms F<3>, which are pivoted to spindles A<4> held by flanges on the frame A. The supporting- arms are geared together at their pivoted ends by toothed wheels F', which are adjustably connected to the arms by set-screws F<2>. To lock the moulds, a threaded spindle z, which passes through eyes F<5>, F<6>, in each half of the casing, is turned by a handle G so that a projecting part on the free end of the spindle embraces the edges of a slot in the eye F<5>. Wear is taken up by passing the spindle through a nut in the eye F<6>, the position of the nut in the eye being adjustable and determined by a fixing-screw z<2> threaded into the side of the eye. The neck moulds are independent of the parison moulds, and carry arms that are hinged to pins in guide brackets A<2> on arms A', the arms A' being integral with the frame. The core-rods D are pivoted to bell-crank levers J, the free ends of the latter taking into a cam groove in a wheel fixed to the shaft on which the apparatus rotates. Each rod is thus thrust into the mould when in the charging position, shown in the right-hand half of Fig. 1, the molten metal flowing under pressure of fluid forced through a pipe N<1> into the cavity round the rod and forming the neck. On being rotated into the position shown on the left-hand side of the Figure, the rod is drawn out of the mould and the bottle blown by fluid forced in through a pipe Q. This pipe is connected with the guide-bracket A<2>; or, the arms A<1> may be made tubular to form a passage way for the fluid. The pipe N<1> is connected by a universal or radial joint with the front end of the tubular shaft, and the fluid flows through the latter to N<1> from a pressure pipe connected to the other end of the shaft. The flow of fluid in the pressure pipe is controlled by a stop valve actuated by a pivoted bell-crank Lever M. This lever also depresses a pivoted bar R by means of a link R<3>. The bar is normally pressed upwards to act as a locking-device for the rotating frame, a recess in it engaging with a pin adjustably fixed in a slotted hole in the frame. The pipe N<1> is formed with a bayonet-joint and swivelling handle N<3>, by which it can be connected with either of the parison moulds. An independent pressure pipe P supplies fluid to blow the bottle proper. A control valve P<1> in it is actuated by a knee-lever P<2>, and the pipe is connected to a passage P<4>, Fig. 10, in the stationary part of the machine. In the two working positions of the frame A, the passage P<4> coincides with one of the pipes P, and fluid is thus delivered to the parison mould. The parison mould having been swung round into blowing position shown on the left-hand side of Fig. 1, the tube N<1> is removed, and an end cup mould U is raised up by levers U<1>, U<2>, U<3> and a handle U<5> to complete the parison mould. The bottle is blown in the complete mould, and both sections and the bottom of the mould removed from the bottle, which then hangs from the neck moulds D<1>. Finishing-moulds T pivoted similarly to the parison moulds on a standard S are then swung round to embrace the bottle, an end disc mould V raised to complete the finishing-mould by a rod V<7>, chain, and wheel V<4>, and the bottle fully blown. The parts of the finishing-mould are then removed, and a disc W on an arm W<1> is swung round on its supporting shaft W<2> and lifted vertically to take the bottle from the neck mould D<1>, which is opened to release it. A radiating casing X, consisting of a metal tube with radiating vanes or ribs and either loose or fixed to the end of the arm W<1>, surrounds the bottle as it cools on the disc W. A rod X<1> is raised vertically by a weighted chain X<4> and wheel X<8>, and lifts the bottle neck into a hood Y, which is heated by a ring gas burner Y<1>. When bottles are being made with screwthreaded necks, the levers J are dispensed with, and the brackets A<2> are screw-threaded. To screw in the neck core-rods, a hand-wheel may be used ; or, the periphery of the cam-wheel on the hollow mainshaft may have teeth which rotate the rods by means of bevel-wheels and chain gearing.
