17,613. Sowden, A. Aug. 31. Blowing and moulding bottles etc.; r e m o v i n g articles from moulds.- Relates to machines for the manufacture of glass jars, bottles, &c., in which a measured quantity of glass is (1) pressed in a preliminary mould which forms a conical body with a finished neck, (2) transferred to a blowing-mould where the article is finished, and (3) removed from the blowing-mould and delivered to a receptacle which deposits it on an endless belt passing to the annealing-oven. The pressing and blowing moulds are carried on a rotary table 10, Fig. 7, which receives an intermittent motion through the medium of a pinwheel 9 and star-wheel 12. The blow-heads 40 are carried by radial arms 38 turning with the table 10 ; the apparatus for supplying the mould with glass, the press-heads, and the discharging-apparatus are carried by pillars adjacent to the table, so that the moulds are presented to them in turn. The glass is supplied to the press-mould by a ladle or scoop made in two parts so as to divide for the purpose of delivering the glass through a funnel into the mould. The bracket supporting the ladle is splined on a vertical shaft which is adapted to turn through a limited angle, so that the ladle can be swung aside from the funnel and lowered into the tank containing the molten glass. After the mould has received the charge of glass it is brought beneath a plunger 16, Fig. 3, of which there are three, carried by the vertical shaft 17. The pressing-mould is lifted by the plunger 22, and the neck-mould 13<A> is pressed against the die 27. The plunger 16 then descends, and the glass assumes the form shown by the black outline in Fig. 3. The mould now passes to a lifting-device consisting of a pair of fingers which advance and enter into eyes or beneath lugs carried by the neck mould 13<A>. The fingers lift the partly-moulded jar clear of the pressing-mould, and hold it while the table turns through another step so as to bring the finishing or blowing mould beneath it. The blowing-apparatus is shown in Fig. 7. The blowheads 40 are adapted to move radially on guiding-rods 38, so that they may be drawn inwards clear of the mould at the discharging positions. The air valves are automatically opened and closed by means of a curved fixed bar 41<B>, which actuates spring fingers controlling the valves. The depression of the blow-head is effected by a fixed cam surface 47<A>, a cover 42 being then forced tightly down upon the neck mould 13<A>. Air is supplied from the reservoir 46 through pipes 46<A> and rubber tubes. After the blowing operation is completed, the neck mould is opened and removed. The neck mould consists of two halves connected by pins and sockets so as to be capable of sliding apart. A pair of fingers enter the eyes or lugs previously referred to, and open the neck mould so as to release the neck of the jar ; the neck mould is then raised, and the blowing-mould moves on another step. The next operation consists in slightly opening the blowing-mould by the action on two pins projecting from the mould sections of a cam-actuated plate having two inclined grooves. A pair of curved fingers or clips now descend and grip the neck of the jar, which they convey to an open box or receptacle provided with a door. This box is pivoted about a shaft so as to turn downwards and discharge the finished article on to a band, which conveys it to the annealing-oven. The neck mould may be locked, while in position above the blowing-mould, by a pair of catches sliding upon the latter and actuated by suitable levers and cams.
