Abstract: 127,226. Marks, E. C. R., (Adriance Machine Works Inc.). Jan. 21, 1918. Bottling; capsules, applying.-In a machine for filling and sealing bottles and like containers, a continuously-operating driving-means operates an alternating advance-and-pause motion power-transmitting means which is adjustable to vary the ratio of its advances and pauses independently of the driving-means, and the power-transmitting means actuates coacting means for exerting pressure upon the container during the filling operation, or the affixing of a closure, or actuates means for feeding the containers into position, or actuates both of said means. The filling and sealing means move up and down at the front of a housing b, Figs. 1 and 2, carried by a pedestal a, 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 &c. 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 and hermetically sealing the same from the atmosphere. A pause of variable extent in the downstroke takes place during the filling operation, and the closure is affixed during the remainder of the stroke. The bottles are fed to a turret q carried by a shaft which is mounted in a vertically adjustable bracket e, Fig. 14, and operated through ratchet mechanism k, n from a crank 136 on a vertical shaft 135 which is rocked by a cam 132 on a shaft 127 driven through clutch gearing from the driving-shaft 123. A stop r at the end of a shaft s operated by a handle t holds the pawl n between the teeth of the wheel k at the end of its throw. The filling and sealing head 32 is carried by a compensating-slide 31 in a carrier or main slide y, z which is actuated by a lever 134 operated by cams 131 on the shaft 127. As the main slide y, z descends, pivoted pawls 34 run off plates v and engage teeth 33 on the slide 31, after which the two slides descend together. A tubular plunger 39, 40 in the slide 31, and connected at 41a to the liquid supply, is normally depressed by a spring 44 and has a tubular extension 43 with a seat for a valve 52. A spring 54 carried by an arm 55 projecting from the part 37 of the slide 31 engages the spindle 53 of the valve. 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 rela. tively to the plunger, the hook catches under the shoulder 41b. After the pause, the lever 84 is rocked by the shaft 135 and the plunger raised to close the valve. The vertically movable mouthpiece 63 carries a sealing-gasket 64, a ring 65 with a ledge 65a for supporting the closure, and an appliance 66 for affixing the closure. At the top of its stroke, the head 32 lifts a check 89 in the feed-shoot 88 and admits a closure to the inlet 67, and when the slide 31 pauses, a gate forces the closure on to the seat 65a. A clutch member 130 secured to the shaft 127 carries a spring-pressed latch which engages in pockets in a member 126 carried by a wheel 125, which is loose on the shaft 127 and driven by a worm 124 on the driving-shaft 123. A pivoted retractor 144 to engage the latch is operated by a pin 150 on a spring-pressed dog 149, which, by means of a screw 148, can be moved laterally to engage projections of different lengths on the member 126 and thereby produce varying periods of rest in the shaft 127. In a modification, Fig. 10, in which provision is made for longer periods of rest, the projecting parts of the clutch member are carried by a loose ring 154 having a notch 158 to receive a latch 157 on the worm-wheel 151. A spring pin 157b of the latch is engaged by the ring 159<a> of a controller having a thrust-piece 159<b> which passes through the bearing 161 of the shaft 127 and engages a cam-shaped notch 162 in a crank 29 on the shaft 127 under the pressure of a spring 163. When the controller is held back by means of a lever 165, the ring 154 remains locked to the parts 151, 152 and the pause depends only on the position of a dog 149. When the controller is released, the latch 157 unlocks the parts 131, 152. The parts 29, 127, 131 remain stationary during the next revolution of the latch 157, after which the latch 157 engages the notch 158 and picks up the ring 154. After a further pause, depending on the position of the dog 149, another latch 156 picks up the parts 29, 127, 131, and these complete a full revolution before the next pause. A spring pin 164 stops the ring 154 unless positively moved by the latch 157.
