Abstract: 11,426. Blaxter, A. P., Blaxter, A. P., and Chaloner, G. W. May 16. Bottling; capsules, 'crown corks,' and the like, applying.-Relates to a revolving-table machine for filling and sealing bottles, and comprises means for preventing waste of liquid, gas, syrup, or seals, such as crown corks in the event of a bottle bursting or being omitted, and for automatically positioning the crown corks in the composite filling and sealing heads. Syrup, gas, and charged liquid are supplied, and snifting is effected all through a central controlling-valve comprising ported disks 23, 24, Fig. 1, while each composite filling and sealing head 9, Figs. 1 and 2, is provided with a rotary auxiliary valve 54 operated only when a bottle is in position. The central valve is connected by pipes 38, 35, 42 respectively with a back-pressure chamber 40, syrup-supply pipe 36, and liquid-supply pipe 43. The syrup pipe is connected to a pump 72 of ordinary construction. An additional port is provided in the central valve for supplying a jet of fluid through pipes 51 to position the sealing- caps in the filling-heads as described below. The pump-rod 73, Figs. 1 and 7, is normally operated by a rotary cam 80, through a pivoted arm 112, the cam being rotated by a roller 83 adjacent each bottle-support. If no bottle is on the support, a tappet 91 mounted on a vertical rotatable rod 92 strikes a lever 90, an extension 89 of which embraces the pump plunger, and so moves the plunger clear of the operating-cam. The tappet 91 is moved into position to strike the lever 90 by means of an arm 96 striking a stationary tappet 116, before the bottle-support reaches position in which an empty bottle is inserted. The tappet is moved into inoperative position by the bottle, when placed in the rest, pressing back an arm 93 and so rotating the rod 92. After the passing of an empty bottle-support, the tappet 91 resets the pump-driving mechanism by striking a plate 97, Figs. 7 and 9, on a lever 98 which engages a recess 100 in the lever 90. Also, a projection 102 on the lever 98 operates a lever 103, Figs. 1 and 7, to project a tripper 107 into the path of the operating-lever 63 of the corresponding auxiliary valve. The tripper 107 is withdrawn by the tappet 91 striking the plate 97. A fixed tappet 117, Fig. 1, ensures each auxiliary valve being turned on after passing it. Auxiliary tappet mechanism is provided to close the corresponding auxiliary valve if a bottle bursts. This comprises a flexible plate in the path of the arm 96. So long as a bottle is on the support it will resist movement of the arm 93 and also of the arm 96, the flexible plate yielding to allow the arm to pass. If a bottle bursts, the arm 93 will be free to move and so the rod 92 will be rotated by the engagement of the arm 96 with the flexible plate and will move the tappet 91 into position to engage a weighted lever and project a tappet into the path of the operating-lever of the auxiliary valve, which is turned off for the remainder of the rotation of the machine. After the passing of the bottle support, the lever and tappet are returned to inoperative positions by the weight. During filling, a tight joint with the bottle is made by a gasket 13, Fig. 2, compressed by levers 17 and hooked arms 19, Fig. 1, operated by a roller 16 and a central cam. After filling, the bottles are further raised into crowniug position by the cam track. Crowns are fed down a shoot 67, Figs. 1 and 2, through blades 144, 145 under control of a lever 142 pivoted at 149 and operated by the crowning-plunger 137 during the rotation of the machine so that no cap is fed unless a bottle is in position. The crowns are positioned against a guard-ring 68, and their rebound is prevented by a jet of water admitted by the pipes 51 under control of the central valve.
