Abstract: 241,637. Gibbins, G. M., and Hayward, Tyler, & Co., Ltd. July 26, 1924. Bottling; " crown corks," applying. - In a rotary bottle filling and crown-corking machine. comprising a bottle feeding and holding device having an intermittent rotary motion, the crowning head is mounted on a vertically guided column reciprocated by means of a crank and connecting-rod, an eccentric, or cam device on a shaft driven continuously from the driving or main shaft. A driving shaft w, Figs. 1 and 7, mounted in a standard 5 on a base a rotates through gearing 6, 7, 10 a crank shaft s mounted in a hollow standard b and adapted to reciprocate a pillar 12 upon the top of which a crown-corking head 14 is adjustably mounted. The standard b supports a table f above which a feed wheel i is keyed to a sleeve d surrounding a column c extending upwardly from the standard b. To rotate the feed wheel intermittently the crank shaft s rotates a vertical shaft r continuously through mitre gearing t, u and a one-toothed pinion or crank arm g engages a star or spur wheel e on the sleeve d. The feed wheel i is formed with pockets or recesses 24, Fig. 3, each provided with a pair of pivoted gripping arms or levers 25, 35 which are urged by springs 27, 37 to maintain the closing position in which they grip the bottle. As the feed wheel rotates, a fixed cam 30 beneath the wheel engages one arm 29 of the lever 25 and opens the grippers to allow a bottle to be placed therein, the arm closing and gripping the bottle when the cam is passed. The feed wheel moves the bottle along the table f, on to one of the bottle rests 52 of a rotary filling machine mounted on the standard 5. At this point an adjustable stationary cam 31 releases the lever 25 and a lever 38 actuated by a cam 41, Fig. 1, on the shaft s releases the lever 85 35 from the bottle. To allow bottles of different diameters to be centred on the bottle rest, the feed wheel i is provided with four key ways 43 .. 46 which may be different distances apart. and any one of which may be registered with a keyway 47 on the sleeve d. A hollow column 65 on the standard 5 supports a casing 51 carrying bottle rests 52 and secured to a member 49 which is rotated continuously through worm gearing 50, 98 by the driving shaft w. A fixed cam 100 on the standard 5 depresses the bottle rests to the level of the feed table f as they approach it and thereafter allows them to raise the bottles to the filling mouthpieces. To adaptthe filling mechanism for adjustment to bottles of different sizes, it is supported on a non- rotatable pillar 54 which is screw-threaded at its lower end to engage a threaded worm wheel nut 55 rotated to raise or lower the pillar by a worm 56 on a shaft 57 provided with a hand wheel 58. At its upper end the pillar carries the rotary portion 78 of a face leather distributing valve, the fixed portion 74 being secured to a non- rotatable ring 59 made adjustable in unison with the pillar 54 by mounting it on similar pillars. 113 adapted to be raised and lowered by worm wheels 115, 116 operated by worms on the shaft 57. Syrup is supplied through an inlet 79 to the part 74 of the distributing valve by a pump 105 mounted on the ring 59 and actuated by an articulated arm 102, 103 carried by the support 13 of the crowning head 14. A pin which keeps the articulation rigid may be removed to allow the operating end of the arm to be disconnected from the piston rod 104 of the pump 105. A second inlet in the part 74 admits aerated liquid. Mouthpieces 61 are connected to the rotating part 78 of the valve by pipes 77 in which filling valves 76 are disposed, the valves being actuated at the correct times by cams or tappets 95 secured to the ring 59 and acting through levers, 90. The pivot 91 of each lever 90 is mounted in a slot in the mouthpiece bracket 92 and a spring 93 draws inwards its lower end. When a bottle is in position it forces the pivot 91 to the inner end of the slot and the lever actuates the filling valve; otherwise the play allowed by the slot prevents its actuation. Each mouthpiece 61 is provided with a snift valve 88 actuated by a cam on the underside of the ring 59. Guards 96, 97 prevent injury from a bursting bottle. The filled bottle is presented to the feed wheel i, the arm 25 being moved outwards to receive it by a cam 32, Fig. 3, and is moved beneath the crowning head 14 where it rests upon a support k upheld by four weak springs l, to give a less harsh crowning action. To adjust the crowning head for bottles of different heights, a worm-wheel nut 19, mounted in bearings on the head but restrained from axial movement relatively to it, engages a thread on the column 12, rotation of a hand wheel 23, on a shaft 20 carrying a worm which engages the nut 19, raising or lowering the crowning head.
