Abstract: 246,584. Blaxter, A. P., Chaloner, G. W., and Blaxter, A. P. L., (trading as Barnett & Foster). Oct. 31, 1924. Bottling; ' crown corks' and the like, applying.-A machine for syruping, filling and sealing bottles comprises three units, each performing one of these functions and having its bottle support or supports adapted to raise and lower the bottles from and to a fixed normal level relatively to its head or heads, the machine being provided with means for transferring bottles from one unit to the other in series and with means for raising or lowering simultaneously the heads of all the units relatively to the fixed normal levels of their bottle supports. A hollow stationary column 2, Fig. 3, on a base 1 is surrounded by a rotating sleeve 3 carrying a disc 4 on which bottle supports 5 are mounted. Within the column 2 a non-rotatable shaft 13 is adapted to be raised and lowered by rotation of a worm 18 which engages a threaded worm wheel 17 at the lower end of the shaft. The shaft 13 supports an upper column 20 to which a distributing box 21 for filling heads 22 is secured, the box 21 also carrying syruping and crowning heads 36, 37, Fig. 1, so that movement of the shaft 13 adjusts simultaneously the syruping, filling and crowning units of the machine. Bottles, fed to the machine by hand or mechanically, are transferred singly to the bottle rest 55 of the syruper by a pair of grippers, which simultaneously transfers a syruped bottle to a bottle rest 5. The pair of grippers comprises two bars 60 formed with V-shaped ends and mounted on levers 62 secured to horizontal guard members 54 which ward off any spilt liquid. The guards 54 are secured to sleeves 51 adapted to oscillate about shafts 64<1> and are formed with knuckle levers 64, the bosses 63 of which engage a member 65 adapted to be raised or lowered to open or close the grippers by a rod 69 to which it is connected by a roller 67 and a slotted link. The rod 69 is actuated against the action of a spring 80 by a rocking lever 70 engaged by a cam 72 on a cam shaft 42. The slotted link allows horizontal motion to be imparted to the sleeve 51 and so causes the grippers to move the bottle to or from the rest 55. To effect this, a casing 66 surrounding the member 65 is secured to an arm 76 rigid with a rock shaft 77<1> oscillated through a link 79 by a cam 78 on the shaft 42. During the transference of an empty bottle to the syruper a syruped bottle is transferred to a vacant bottle rest 5 on the filling machine, the rest 5 being supported by its, roller 6, below its normal level on a movable section 38 of a horizontal circular track 7. To raise the bottle rest to the track 7 to force the bottle into the filling head 22, a cam 41 on the shaft 42 raises a pivoted arm 46 on which the section 38 is mounted. The bottle passes around the filling machine to a point opposite the crowning head 37 to which similar mechanism transfers it and eventually discharges it from the machine. The Provisional Specification describes rotary turrets associated with the syruping and sealing units and provided with three sets of grippers for transferring the bottles between the syruping, filling and sealing units. Specifications 183,285, 246,733 and 246,762 are referred to.
