Abstract: 505,582. Filling pots &c. with pasty material. AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. Nov. 12, 1937, No. 31170. Convention date, Nov. 14, 1936. [Class 125 (ii)] In a device for filling pots or like containers 1 with paste and having a filling spout 12, Fig. 2, adapted to be introduced into the container and a cover 17 embracing and being longitudinally movable relative to the spout, 12 and which tightly engages the opening of the container, one or several apertures, e.g. the annular space between the cover and the nozzle 12 or the openings 54, Fig. 5, are provided in the cover for the discharge of air and filled surplus material from the container in combination with means for withdrawing the spout and the container from one another simultaneously as the cover still engages the container and the last part of the material is supplied thereto. The spout 12 may have lateral channels 13 which also serve for the discharge of air and filled material from the container or may have exterior longitudinal slots 52, Fig. 7. The pots 1 are conveyed by a chain 2 stepwise upon a table 3 to the filling device 4, Fig. 1, and then to a device 5 for smoothing the surface. The filling pipe 7 is supplied, e.g. with paste, by means of the pump described in Specification 424,673, [Group XXVIII], and is held within a sleeve 9 rotated by gear wheels 10, 11. The nozzle 12 is mounted within a casing 14 having a discharge pipe 16 and an annular cover plate 17 provided with an elastic packing ring 19. The plate 27 carrying the pot 1 is moved upwards by the cam disc 29 so that the upper rim of the pot tightly engages the packing 19. The spring 22 is compressed until a shoulder 32 on the spindle 26 engages the arm 25 so that the sleeve 24 is lifted, the casing 14 being moved upwards and the filling spout being introduced into the pot. Paste is then forced out of the pipe 7 which is simultaneously rotated and during the filling operation air, and ultimately surplus paste, is, discharged from the pot through the channels 13 and the narrow annular space between the nozzle 12 and cover 17. The plate 27 may be shaken to assist filling. Alternatively the tube 7 may be shaken by a lever 31 actuated by a cam disc 30. At the end of the filling operation the lower ends of the nozzle 12 and cover 17 are at the same level and the arm 25 will rest on the table 33. The conveyer 2 moves the filled pot from the plate 27 on to the table 3 and it is then advanced on to a carrier plate 49 below a smoothing device 5. The plate 49 is mounted on a spindle 67 slidable in a sleeve 68 and is operated by a cam disc 72 to lift the pot 1 so that the upper rim engages a plate 34, Fig. 3, secured to a spindle 40 movable longitudinally within a sleeve 39 which is rotated rapidly by gear wheels 47, 48. The cam disc 72 holds the sleeve 68 at a piedetermined height for an interval, then the arm 44 slowly lifts the spindle 40 and the plate 34 so that the plate 49 ascends until the pin 70 engages the sleeve 68 ; the arm 44 then continues to lift the plate 34 off the pot 1. The plate 49 is then lowered and the pot moved aside while the plate 34 is raised between scrapers 35 which remove adhering paste. The Specification as open to inspection under Section 91 comprises also a modification wherein the cover may constitute a table adapted to support the containers in an inverted position. This subject-matter does not appear' in the Specification as accepted.
