380,801. Galvanic batteries. BUMKE GES., H. A., 8, Chausseestrasse, and AUTOM SPEZIAL-MASCHINEN GES., 5, B³lowstrasse, both in Berlin. June 15, 1931, No. 17396. Convention date, Aug. 5, 1930. [Class 53.] In a machine for making dry batteries which places the covers on the zinc containers, caps the carbon rods and solders the pole wires to the containers, a conveyer is employed which moves in a straight line and which comprises a movable part 20 which embraces a fixed part 19. The movable part slides on the outer faces of the fixed part and is mounted on arms 21 which are rotatable on crank pins 22 projecting from discs 23 which are rotated by worm wheels 25. The movement of the arms 21 first lifts the conveyer, then advances it and then lowers it again. The cells normally rest on the fixed member 19 but are lifted by the upward movement of the part 20 and are carried forward until the part 20 is again lowered when the cells are again laid on the part 19. Both edges of the movable part are formed as racks to receive the ends of the cells which are first conveyed to a centring device 2 which centres the carbon rod in the zinc container of each cell before the cover is put on. The cell is then conveyed to the device 3 which punches out covers from a cardboard strip and places them on the containers over the carbon rods. The covers are pressed tightly into position by a device 4 and the cells are then conveyed to a capping device 5 and finally to a conveyer disc 11 of a soldering device. The disc 11 carries the cells first past a device 12 for wetting the containers with spirit and then to a device 13 which draws the pole wire into position for soldering and cuts off pieces of the required length. The cells with the wires held in the correct position are then brought up to the soldering device 14 which automatically solders the wires in position. Specification 380,475 is referred to. |
