Claim 1

IN A MACHINE FOR THE AUTOMATIC ASSEMBLY OF SHEETS OF PAPER, SAID MACHINE INCLUIDING A FRAME, THE COMBINATION OF: A MAGAZINE COMPRISING ADJACENT PIGEON HOLES EQUAL IN NUMBER TO THE NUMBER OF SHEETS TO BE ASSEMBLED IN ONE BOOKLET, EACH PIGEON HOLE BEING ADAPTED TO RECEIVE A PARCEL OF SHEETS OF A SINGLE PAGE OF THE BOOKLET IN THE ORDER THEY ARE TO FOLLOW IN THE BOOKLET, SAID PIGEON HOLES BEING INCLINED WITH RESPECT TO THE VERTICAL BY AN ANGLE COMPRISED BETWEEN 15* AND 45*, SAID PIGEON HOLES BEING DIVIDED IN HEIGHT INTO TWO TELESCOPIC PARTS, THE UPPER PARTS OF WHICH ARE FIXED TO THE FRAME WHILE THE LOWER PARTS, CONNECTED BY SIDE BARS, CAN BE RAISED OR LOWERED AS A UNIT WITH RESPECT TO SAID UPPER PARTS TO ADAPT THE EFFECTIVE HEIGHT OF THE PIGEON HOLES TO THE SIZE OF THE SHEETS TO BE ASSEMBLED, SAID MAGAZINE ALSO COMPRISING MOVABLE HORIZONTAL BARS ARRANGED SYMMETRICALLY WITH RESPECT TO THE LONGITUDINAL MEAN VERTICAL PLANE OF THE MAGAZINE, WHICH BARS CONSTITUTE THE LATERAL WALLS OF THE PIGEON HOLES, WHICH HORIZONTAL BARS ARE SYMMETRICALLY MOVABLE TOWARDS OR AWAY FROM SAID MEAN VERTICAL PLANE SO AS TO ADAPT THE EFFECTIVE WIDTH OF THE PIGEON HOLES TO THE SIZE OF THE SHEETS TO BE ASSEMBLED; AN ELEVATING DEVICE ADAPTED TO MOVE SHEETS ONE BY ONE FROM EACH PIGEON HOLE IN ORDER TO PRESENT THEM SIMULTANEOUSLY TO THE ASSEMBLING DEVICE, SAID ELEVATING DEVICE COMPRISING AS MANY FINGERS AS THERE ARE PIGEON HOLES, ONE END OF EACH FINGER RESTING ON THE UPPER SHEET IN EACH PIGEON HOLE, EACH FINGER BEING ATTACHED BY ITS OTHER END TO A HORIZONTAL LONGITUDINAL MEMBER, LEVER MEANS TO MOVE SAID HORIZONTAL LONGITUDINAL MEMBER PERIODICALLY UPWARDS AND DOWNWARDS, MEANS BEING ATTACHED TO SAID MEMBER AND ROTATING ABOUT AN AXIS FIXED IN RELATION TO THE FRAME AND PERPENDICULAR TO THE LONGITUDINAL VERTICAL AND SYMMETRICAL PLANE OF THE MACHINE, A ROTATING CAM FOR ACTUATING ONE OF SAID LEVERS, THE PROFILE OF SAID CAM CAUSING UPWARD AND DOWNWARD MOVEMENT OF SAID LONGITUDINAL MEMBER SO THE MOTION IS TRANSFERRED TO SAID FINGERS, THE AXIS OF THE CAM BEING FIXED WITH RESPECT TO THE FRAME, THE FINGERS BEING PROVIDED WITH TILTING SKIDS WHICH ARE ADAPTED TO MOVE THE UPPER SHEET UPWARDS DURING THE UPWARD MOVEMENT OF THE FINGERS, AN ASSEMBLING DEVICE WHICH SUPERIMPOSES THE SHEETS IN THE DESIRED ORDER AND CONVEYS THEM TO THE RECEIVING DEVICE, SAID ASSEMBLING DEVICE COMPRISING A GRIPPING MECHANISM ARRANGED ABOVE EACH PIGEON HOLE OF THE MAGAZINE WHICH GRIPS THE SHEET RAISED BY THE ELEVATING DEVICE AND PROPELS IT TOWARDS A RECEIVING DEVICE, SAID ASSEMBLING DEVICE BEING FORMED SUBSTANTIALLY OF TWO ROLLERS TURNING FREELY ABOUT TRANSVERSE SPINDLES AND BETWEEN WHICH THE UNDER STRAND OF ENDLESS BELTS PASS, SAID BELTS BEING DRIVEN TO PRODUCE A CONTINUOUS LONGITUDINAL MOVEMENT, THE SPINDLE OF THE LOWER ROLLER BEING FIXED ADJACENT THE UPPER END OF A CORRESPONDING PIGEON HOLE WHILE THE SPINDLE OF THE CORRESPONDING UPPER ROLLER IS CARRIED BY TWO LEVERS ARTICULATED TO A FIXED PIVOT, SO THAT THE UPPER ROLLER CAN OSCILLATE DOWNWARDS SO AS TO WEIGH ON BELTS AND APPLY THEM FIRMLY TO THE LOWER ROLLER OR ON TO SHEETS ENGAGED BETWEEN THE LOWER ROLLER AND THE BELT; AND A RECEIVING DEVICE IN WHICH THE SUCCESSION OF BOOKLETS THUS CONSTITUTED ARE STACKED, SAID RECEIVING DEVICE CONSISTING OF A VERTICALLY MOVABLE COMPARTMENT COMPRISING A BOTTOM PLATE TO RECEIVE THE BOOKLETS TO BE STACKED, AN END WALL PLATE AGAINST WHICH THE BOOKLETS ARE STACKED AS THEY LEAVE THE ASSEMBLING DEVICE, AND VERTICAL SLIPPING GUIDES SECURING THE BOTTOM OF SAID COMPARTMENT TO THE OUTLET FACE OF THE FRAME SO SAID COMPARTMENT IS LOWERED AS BOOKLETS ARE ADDED TO THE COMPARMENT, SO AS TO MAINTAIN THE TOP OF THE PILE OF BOOKLETS BETWEEN TWO PRESELECTED LEVELS.
