Abstract: 130,352. Marks, E. C. R., (Adriance Machine Works, Inc.). Jan. 21, 1918. Bottling; capsules, applying.-Relates to machines for filling and sealing bottles and like containers and of the type in which the flow of liquid to the container is controlled by means of the upward pressure of the container against the filling- head. The filling and sealing means are adapted to co-operate with one another for exerting pressure on the container to control the flow of liquid to the container and affix a closure thereto. The syrup delivery, filling, and sealing means are carried by a vertically reciprocating slide, and the bottles are advanced step by step to position them with respect thereto. On the down-stroke, one bottle receives syrup and another is filled with carbonated water and capped or sealed. Means are provided for compensating for bottles of varying heights and for forcing the filling and sealing head over the bottle to seal it hermetically from the atmosphere. A pause in the down-stroke takes place during the filling operation, and the closure is affixed by continuing the down-stroke after the pause. The bottles are fed to a turret q, Figs. 1 and 13, carried by a shaft j which is mounted in a vertically adjustable bracket e on the pedestal a and operated through ratchet mechanism k, n. A stop r, at the end of a shaft operated by a handle t, holds the pawl between the teeth of the wheel k at the end of its throm. The slide y, z, Figs. 5 and 17, carries the syrup delivery, filling, and sealing means, the receiver 12, 13 of the syrup-dispensing device being reciprocated in a guide u by a friction grip 16 operated by the slide y, z. On the downstroke, the spring-pressed mouthpiece 17 engages the bottle, and a valve 22 is opened against the pressure of a spring 23 to permit syrup to be delivered from a pump. The pump has a yielding piston operated by an adjustable crank-pin, and a valve 21 prevents back-flow of syrup on the up-stroke. As the main slide y, z descends, pivoted pawls 34 run off plates v and engage teeth 33 on a slide 31 which carries the head 32, after which the two slides descend together. A tubular plunger 39, 40, Fig. 5, in the slide 31, and connected at 41<a> to the liquid supply, is normally depressed by a spring 44 and has a tubular extension 43 with a seat for a valve 52. The extension 43 contains a screw 45, Fig. 8, with an angular port 45b discharging into a chamber 46 which contains a hollow foam-retarding capsule 47<a>. The chamber 46 receives liquid evicted from the bottle and is provided with a screwadjusted outlet 47. A spring 54, carried by an arm 55 projecting from-the part 37 of the slide 31, engages the spindle 53 of the valve 52. When the plunger engages the bottle and the slide 31 is subsequently depressed relatively to the plunger, a spring dog 58 operates the spindle 53 and opens the valve. A lever 84 on the extension 37 has a depending hook 86 pressed against the part 41 of the plunger by a spring 87, and when the slide 31 moves relatively to the plunger, the hook catches under the shoulder 41<b>. After the pause, the lever 84 is rocked and the plunger raised to close the valve. The vertically movable mouthpiece 63, Fig. 8, carries a sealing-gasket 64, a ring 65 with a ledge 65<a> for supporting the closure, and an appliance 66 for affixing the closure. The mouthpiece is held up, with the gasket compressed, by means of spring-pressed rods 69 passing through tubes 68 slidable in the bracket u. For releasing the gasket after the filling and sealing operations, rollers 73 on the rods 69 bear against a forked lever 74 which engages a notch 75a, Fig. 5, in a rod 75 slidable in a block 77. The rod 75 descends with the head 32 until it is stopped by toothed dogs pressed against a toothed surface on the rod by a lever 83, Fig. 1, whereupon the lever 74 is operated to force the mouthpiece downwards. At the top of its stroke, the head 32 lifts a check 89, Fig. 5, in the feed-shoot 88 and admits a closure to the inlet 67, and when the slide 31 pauses, a spring pusher forces the closure on to the seat 65a. The closures are fed from a hopper x by a rotating disk 106 having a groove 108 registering with a rib 113 at the end of the sloping bottom 105 of the hopper. The disk is flanked by a concentric flange 111 and carries two concentric sets of agitators 115 engaging its holes. Any closures caught between the groove 108 and rib 113 are dislodged by the outer set of agitators, while any that would clog the outlet are advanced along the flange 111 back toward the hopper by a toothed agitator 116 gearing with the disk 106. The means for effecting properly timed movements of the various parts of the machine are described in Specification 127,226.
