Abstract: 5996. Ferguson, T. March 12. Bottling.-Relates to turn-over machines of the kind described in Specification No. 17,942, A.D. 1891, for filling internally-stoppered bottles, and comprises particularly the construction of the bottle holders and filling-heads, the arrangement of the filling, syruping, and vent passages, and means for operating the syrup pump. The machine is preferably adapted for filling two bottles, which are mounted in bottling-arms A connected by unions C<2> to the main spindle C<1>. Each bottling-arm comprises a filling-head A<5> and a bottle clamp A'. The clamp A<1> is attached to a loop lever A<4> pivoted to the arm A, and is held in engagement with the bottle by a spring a<5>, Figs. 1<b> and 2. The rear end of the lever A<4> is adapted to receive a wedge A<2>, which works in a slot a<10> of the arm A and is connected by a slotted link b<3> and spring b<4> to a fork lever A<3> pivoted at a to the arm A. In operation, at the completion of the filling operation, the clamp A' is raised to release the bottle by a lever B pivoted in the frame and operated by a cam b<2> on the driving-shaft. C. A tappet b on the lever engages a projection a' on the lever A<3>, and so raises the clamp after the wedge has been freed. The filling-heads A<5>, Fig. 4, comprise rubber seats a<2> held in place by metal rings a<3> and screw caps a". They are provided with central vent tubes a', connected through the main spindle C' to a chamber c<2> attached to the valve-box D, which is stationary. The chamber c<2> contains a valve c<3>, Fig. 10, the position of which is indicated by a finger c' and dial c<5>, to regulate the vent discharge. From the chamber c<2>, a pipe a<9> leads the waste. In a modification, a screw-down vent valve, Fig. 16, may be used. The rubber seats a<2> of the filling-heads fit loosely, in order that the liquid pressure on'their outer walls may assist in seating them around the mouths of the bottles. Each bottling - arm is provided with a kick-off for the filled bottle, consisting of a pivoted arm e operated by a spring e'. Fig. 10 shows a section of the end of the spindle C<1> and the stationary valve-box D, between which a leather washer d<6> is situated. The valve-box is provided with branches D' to receive the syrup pipes, and a branch D<2> for the aerated water. Syrup is fed to the pump through the lower branch D', passages in the end of the spindle, and up through the top branch. It is then led from the pump through the upper branch D'and a passage d<4> in the valve-box which terminates in a slot d<5> adapted to register with a passage leading to the bottle during the rotation of the bottle holders. The piston-rod E of the syrup pump is worked by a pivoted lever E<2> operated by an upper and lower cam on the spindles C, C' respectively. The stroke is adjusted by a screw pin E<4> adapted to come in contact with a lug E<6> on the frame. To prevent the spindle C' from rotating while a filled bottle is removed and an empty one inserted, a pause gear F, F', Figs. 2 and 14, is employed. In a modification of the bottle holders, shown in Fig. 16, a bifurcated lever A<6> is pivoted on the opposite filling-head A<5> and is pressed by means of a spring A<7> on the bottle clamp A'. This form of head may be applied to a single-head filling-machine. A modified form of clamp locking mechanism for a single-head filling-machine is shown in Fig. 17. A spring- controlled lever G is pivoted at g and provided at its upper end with a wedge-shaped lug G<1>and at its lower end with a friction roller G<2> adapted to engage a lug g<1>on the bearing of the main spindle during the rotation of the bottle holders. The lever is adapted to withdraw the lug G<1> from behind the tail-end h of the hand-lever H connected to the clamp A'.
