Abstract: 818,838. Battery pasting machines. ELECTRIC STORAGE BATTERY CO. Nov. 13, 1957, No. 35413/57. Class 53. A machine for pasting accumulator grids joined together in pairs to form panels which are eventually severed comprises a base 10 on which is slidably mounted a panel feed unit 11 and a fixed paste feed unit 16. The unit 11 can be moved away from unit 16 by a handle 17 and a system of links for the purpose of cleaning and adjusting and replacing parts. The grid panel feed mechanism comprises spaced conveyer chains 27 engaging sprockets shafts 28, 29, the shaft 28 being mounted in adjustable bearings 30. The grid panels are suspended by their projecting lugs between the chains 27 and are carried towards a pair of rotating discs 32 having notches 31 to receive the grid lugs. The panels are delivered by the discs to a flared opening 34 between bars 35, 36 and as the panels are moved downwards they are engaged by oppositely rotating rollers 39, 40, the spacing between which can be adjusted. The rollers feed the panels into the space be. tween a bar 44 and bars 45, 46 and then between paste-applying adjustable rollers 47, 48 and trowelling or smoothing bars 49, 50. The pasted panels leaving the bars 49, 50 drop between conveyer chains 72 which carry them to the rear of the machine. The bar 46 is provided with openings corresponding to the openings in the grid panels and can be replaced by other bars having different openings corresponding to different panels. Paste feeding mechanism.-A hopper 77 filled with paste has an adjustable front wall 80 and a hinged or otherwise removable bottom 81. The wall 80 is biased in a forwardly and downwardly direction by springs 98, 93, and can be adjusted by a knob 91. The lower end of the wall 80 is formed with a foot 100 to which is adjustably secured a scraper 101 which bears against a paste feed roller 105 and against the bar 46. The roller 105 is loosely mounted to permit of upward and downward, as well as forward and rearward, movements. The bearings of the roller 105 are so connected to the wall 80 that the wall and roller move upwardly and downwardly together, so that the scraper 101 always engages the roller 105. The latter may, however, be adjusted independently of the wall 80 and scraper 101 in order to compensate for wear, and to ensure parallelism between the roller and the roller 48. Agitating and paste-feeding paddles 122, 121 rotate in opposite directions within the hopper. Excess paste discharged from the roller 47 accumulates in a trough 133 from which it is removed manually and returned to the hopper. Powder falling from the discs 32 is caught by a shield 135 which directs it on to the roller 47 which rolls it into the paste being applied to the panels. Operating mechanism.-Figs. 1 and 3 show opposite sides of the machine, power being derived from a motor 137, Fig. 3, and speed reducer 139 which drives a main countershaft 144. The various rollers and the paddles 121, 122 are provided with stub shafts that engage in bearings on opposite sides of the machine. The rollers 39, 40 carry meshing gears 145, Fig. 1, so that they rotate in opposite directions, these gears being rotated by a sprocket chain 146, Fig. 3. The rollers 47, 48 carry meshing gears 147 rotated by the chain 146. The gears 147 are of unequal size so that the rollers 47, 48 rotate at different speeds. The paddles 121, 122 are driven by a chain 148, Fig. 3, and the paste feed roller 105 is driven by a chain 151, Fig. 1. The carry-away conveyer chains 72 are operated by a chain 152, Fig. 3, and the discs 32 by a chain 153. Specification 624,963 is referred to.
