Abstract: 912,215. Feeding sheets. DE LA RUE INSTRUMENTS Ltd. May 15, 1961 [June 9, 1960], No. 20384/60. Class 100 (1). [Also in Group XIX] Separate stacks of bank notes are supported so that any selected stack can be brought adjacent a sheet-separator which removes the sheets sequentially from the stack, and each sheet is then fed by feed rollers through a sheet-counting means. As shown, there are five stacks A . . . E, each stack containing notes of the same value, which value differs from that in the other stacks, and notes in the stack D can be separated by an oscillating sucker 12 which places them between a complete roller 13 and a part-cylindrical roller 14. The notes are then fed by rollers 15 . . . 18 and 21, 22 on to a stacker 23 beneath a driven friction roller 24. Known calliper means associated with the rollers 13, 14 detect doublefeed or crumpled notes, and cause a deflector 19 to divert such notes into a hopper 20. One of the rollers 21, 22 is electrically insulated and a passing note thus breaks the current in a counting system associated with the rollers. Pile-tables.-A frame comprising braced channel rails 25, 26 slidably supports the five stack compartments A . . . E which are formed by two side plates 1, five inclined shelves 2. and upper and lower flanges 4, 5 to support a stack 3 on each shelf. A roller carriage 6 urges each stack towards the flanges 4, 5. The plates 1 have rollers 30 which engage the rails 25, 26, and a tranverse channel 35 on one plate 1 is engaged by a roller 34 secured to an endless chain 31 mounted on sprockets 32, 33, whereby movement of the chain causes vertical up and down movements of the stacks 3. The weight of the stacks is counterbalanced by a weight 55 on a rope 54 attached to one plate 1 and passing over pulleys 52, 53 on the rail 26. A plate 29 secured to the rail 25 supports a motor 40 which drives the shaft 37 of the sprocket 33 through worm gearing 39, 41; a pulley 45 on the motor shaft co-operates with a brake 46 which can be released by a solenoid 48. A vertical control shaft 42, driven by bevel gears from the sprocket shaft 37, is provided with five adjustable cams A 1  . . . E 1 , each arranged to operate three sets of contacts such as 420. On selecting the appropriate switch in the circuit, the motor 40 will automatically position the selected stack compartment opposite the note-separating sucker device 12. Pilot lamps are are illuminated to show which compartment is in position. Of the three sets of contacts in each switch 420, one set is associated with a counter unit (see Group XIX), adapted to record individual monetary values of the particular notes passing through the counting rollers 21, 22; in addition, the counting units provide an aggregate total of all sums of money taken from a number of compartments forming a batch of delivered notes. The counting units may be associated with a relay and a dialling system such that notes are taken from various stacks, the stacks being moved into position automatically. In a modification, the various compartments may be assembled in transversely abutting relationship, or in radial relationship, instead of one above the other. Specification 898,715 is referred to.
