660,553. Batteries. BURNDEPT, Ltd., and RICHARDSON, R. P. Oct. 21, 1947 [June 25, 1945], No. 16165/45. Class 53. [Also in Group XXX] Dry batteries of the layer type are made by first stamping out the zinc cups and then placing them on the platform 7 of the apparatus shown in Fig. 6 and in plan in Fig. 8, which delivers them upside down into carriers 19 which are placed manually on a conveyer 16. The cups are placed mouth upwards on the platform 7 which has a sloping portion down which the cups slide towards a number of tubular or covered shoots 8 at the upper ends of which are rollers 11 which pass the cups singly down the shoots. The rollers 11 are rotated continuously through gearing from a motor 14. The shoots are curved backwards at their lower ends and the cups are therefore inverted when they reach the lower ends of the shoots where they are arrested by loaded hinged stops 13 until picked up by the carriers 19. Fig. 5 shows in section one of the carriers which consists of a frame 2 having a number of V-shaped members 3 for supporting the inverted cups 4. Side members 5 are provided with lugs 6 by which the carrier can be supported in a centrifuge. The conveyer on which the carriers are placed comprises two parallel chains 16 having lugs 18 which sweep over two fixed rails 17. The filled carriers are passed through a station where the bottom surfaces of the cups are coated with the material forming the positive electrodes of the cells. The coating operation may be performed by pouring over the outer surfaces of the cups a suspension of finely-divided carbon in a liquid consisting of drying oils and a dissolved plastic. The carrier with the coated cups is then placed in a centrifuge to remove excess liquid and is then removed and placed on a conveyer and passed through a drier. In order to present the cups mouth upwards to enable the cells to be completed a tray 21 having ribs 22 is placed over the cups in the carrier as shown in Fig. 5 and the carrier is then turned upside down and removed leaving the cups standing in rows on the tray from which they can be fed in single file to apparatus for completing the assembly of the cells. Specifications 579,986, 642,361 and 660,554 are referred to. |
