Abstract: 1,061,049. Sack filling-machines. BADISCHE ANILIN- & SODA-FABRIK A.G. Dec. 18, 1963 [Dec. 22, 1962], No. 49916/63. Heading B8C. An apparatus for filling sacks comprises a filling tube, sampling means, weighing means above the filling tube and means for inflating the sacks, control means being provided to initiate the operations of clamping the neck of the sack to the filling tube, inflating the sack, emptying the weighed goods from the weighing means into the sack. In one embodiment a pair of levers 8a, 8b are rotatably mounted on bearings 7 on the filling tube 1 which has a tapering hood 2 with an attached pipe 3 for sucking off dust. The levers are connected at one end by a roller 9 and at the other end one of the levers has a catch 10 which holds the lever in the upper or lower position of an arcuate slot 11. Mounted above the lever 8a is a lever 12 actuating a control valve 14. After placing a sack over the filling tube the roller 9 is lifted thus raising the lever 12 which opens the valve 14 and causes compressed air to flow to a diaphragm pressure cell 17. The pressure cell piston causes forward movement of a lever 18 which causes jaws 23a, 23b to clamp the sack against the filling tube. The lever 18 also actuates a switch 20 causing compressed air to be blown into the sack for a short time and the weighing means (not shown) to empty the goods into the sack. When the filling operation has been completed the roller 9 is returned to the lower position causing the clamping jaws 23a, 23b to return to their original position, the filled sack falling from the filling tube by its own weight. In other modifications the clamping jaws are operated by a double piston or two diaphragm pressure cells, each cell forcing one clamping jaw against the filling tube.

Abstract: 1,028,673. Filling bags; shoots. BADISCHE ANILIN- & SODA-FABRIK A.G. March 19, 1963, No. 10742/63. Headings B8C and B8S. A nozzle for filling valve bags has a lower cylindrical portion 5 (Fig. 1) cut-off on a slope at 5 and partly surrounded by a jacket 6, as shown in section in Fig. 2, to provide an air vent, and the nozzle is fed through its upper downwardly constricted end 2 which may contain a pear-shaped baffle 4 to direct the material close to the walls of the nozzle. The nozzle is preferably lined with polytetrafluorethylene. The jacket 6 preferably has a crescent-shaped flange 7 (Fig. 3, not shown) limiting the penetration of the nozzle into a bag. The nozzle may be fed from a feed weigher, and the bags may be supported during filling on an inclined conveyer belt which removes the bags after filling. Preferred proportions are given for the jacket 6.
