Abstract: 4124. Blaxter, A. P., Blaxter, A. P., and Chaloner, G. W., [trading as Barnett & Foster]. March 3. Bottling; stoppering.-Relates to machines for filling screw-stoppered bottles with beer, or aerated waters, &c. Fig. 2 shows the machme as employed for bottling frothy liquids, and Figs. 3, 4, and 8 show the filling-head and valve mechanism in detail. The bottle with the stopper in position is placed on the rest G, and is raised by the weighted lever H until the mouth enters the filling-head a, where the stopper is gripped by a chuck on the end of the screwed spindle B, b. The spindle is operated by the nut C, which consists of a frame having two antifriction rollers engaging opposite sides of the screw b. The screw is connected by the link n to the operating-lever D on the cam shaft E. On the upward movement of the lever, the nut C is raised, and rotates the spindle B to extract the stopper, after which the nut engages the collar h and raises the stopper clear of the bottle mouth. After the bottle is filled, the stopper is reinserted by a reverse movement of the lever, the stoppering- spindle being forced down by a spring. Prior to the insertion of the bottle, the stoppering-spindle is raised slightly by the forked lever g, actuated by the stud r on the cam F engaging a projection on the rod s. The downward movement of the spindle under the action of the nut C is thus made larger than its upward movement, to ensure the tight insertion of the stopper. The rod s also serves to release the spring-controlled brake y, which holds the bottle-rest immovable during the filling and stoppering operations. The cam F acts through a forked lever L on the gland q<1>, Fig. 3, which tightens the elastic collar p<1> around the neck of the bottle in known manner. The liquid is delivered into the bottle through the annular cove or channel a<1>, Fig. 3, so that the liquid assumes a gyrating motion and flows down the sides of the bottle. The liquid-supply and snift passages b<1>, c' communicate respectively with the passages d<1>, e<1> in the boss f<1>. The passages n<2>, d' are put in communication through the passage k<2>, Fig. 8. in the valve disc g<1>, to admit the liquid. The displaced air and the fob or froth are discharged through the passages e', l<2>, the reduced passage m<2>, and the passage o<2> into the receiver h<1>, the pressure in which can be regulated by the adjustable relief valve i<1>. When an empty bottle is inserted and its stopper removed, the fob from the previous bottle is returned to the empty bottle through the passages o<2>, l<2>, e<1>. When a filled bottle is stoppered, the pressure in the filling-head is relieved through the snift passage p<2>. The movement of the valve g<1> is effected by means of the projections j<1>, m<1> on the cam J engaging with the notches in the weighted rod K, which is connected to an arm on the valve. For filling bottles with aerated waters, the channel a' is omitted, and the valve mechanism is replaced by an ordinary supply valve. A collar p<1>, Fig. 3, may be employed with the bottle-rest shown in Fig. 20, which consists of a support pivoted at x<1> on an adjustable bracket, so that it can be turned into the position shown in dotted lines, to permit the insertion of the bottle. In the case of stoppers having heads of chisel (or thumb-bit) shape, the bottle neck is pressed against an elastic collar in the filling-head. Fig. 29 shows a syrup pump, the operating-lever y<1> of which is provided with an adjustable stud b<2> for operating the liquid-supply valve. The pump piston has a pin-and-slot connection f with the pivoted segment e<3>, which has also a pin-and-slot connection with the lever y'. The connection f<2> enables the stroke of the pump to be regulated, or the pump to be put out of action.
