Abstract: 26,865. Adshead, G. H. Dec. 5. Baling presses; parcelling newspapers.-Relates to a bundling-press, specially applicable for parcelling newspapers as they come from a printing- machine, the papers being fed in, compressed, and tied up automatically. The papers are deposited in piles upon a table 1, Fig. 3, and are moved forwards beneath the pressing-platen 19 by means of fingers 3, which slide in grooves in the table and are carried by slides 4 working on guides 5, and are actuated by means of connecting-rods 6 and cranks 7 on the main shaft 8. The platen 19 for compressing the pile is carried by four pillars 50, Fig. 9, which slide through guides 51, 52, and are provided with cross-bars 53, 54, the former being rigidly connected to the pillars, while the latter slide upon the pillars and are connected by springs 56 to the cross-bars 53. Each cross bar carries a roller 55 engaging cams 48 on the shaft 45, the cams being shaped to raise the platen to admit the pile of newspapers, and to compress the pile while it is tied up. The shaft 45 receives an intermittent rotary motion by means of a ratchetwheel 47 engaged by spring pawls 46, carried by toothed wheels 10, loose on the shaft 45, and engaging toothed segments 9 loose on the shaft 8. The segments are operated from the cranks 7 by means of pins 11 fixed to the cranks, and quadrant plates 12 each of which has two slots 13, 14 in line with each other. The shaft 8 passes through the slot 13, and pins 15 on the toothed segment engage the slots 14, so that the segments and quadrant plates rotate together, while the quadrant plates may move radially relative to the segment wheels. The pins 11 are so disposed as to engage the projections 16 on the quadrant plates when these plates are at the outward extremity of their travel, but pass clear when the quadrants are at the opposite extremity. The position of the quadrant plates is determined automatically by the presence or absence of a bundle beneath the platen 19 by means of a hinged plate 17 arranged beneath the platen and counterbalanced by a weight 18 so as to fly up when free. Links 20 attached to the plate pass one on each side of the cranks 7, and have slotted ends 22 engaging the shaft 8, and carry pins 23 engaging curved slots 24 in the quadrant plates. When a bundle is in position to be compressed, the plate 17 is held down and the quadrants are held in position to engage the pins 11, which then carry round the quadrants through a certain arc. Stops 25, fixed to the gear wheels 10, force back the driving-quadrants to disengage them from the pins 11. The segments and quadrants fall back against spring stops 26, and the pawls 46 move backwards over the ratchet-wheel without rotating it. The parts are returned to their original positions by means of a spring or weight, or friction mechanism, or preferably by means of a cam on the main shaft driving by means of levers the shaft 30<a> which carries a bell-crank lever and a second lever 30<b>, each of which engage pins fixed to the toothed segments. A spring holds the. levers in engagement with the cam. To prevent buckling or displacement of the sheets or newspapers under operation, the plate 17 is lowered before they reach it by means of an extension 32 on one of the links 20, the extension being pivoted to a lever 33, part of which is curved to engage the crankpin so that the quadrant plates are positively moved into the driving position. The platen 19 carries a pair of knotting-devices of the type used in sheaf-binding and harvesting machines, and shown separately in Figs. 10 and 11. The wheel 65 is driven by spur gearing 67, 68 and bevel gearing from the shaft 45, and has teeth 71 to operate the spindle 72, teeth 73 to operate the retainer spindle 74, and a cam-groove 75 to operate the element which cuts the string and draws the knot off the knotting-device. The jaws 76 are opened at the proper moment by the tail end 77 engaging a cam, and are closed by a spring. The knotters are mounted transversely over slots, and co-operate with a pair of needles carried in needlebars 78 which are operated from the shaft 45 by means of a cam 79, Fig. 12, engaging a roller 81, carried by the rod 82, connected through a spring 84 to a lever 85 on a counterweighted shaft 86, which is connected by a lever 87 and link 88 to the holder 78. The eye ends of the needle-bars are pivoted, and are normally held vertical by a spring. At the top of their travel the bars strike deflectors 92, Fig. 3, which force over the needle points to carry the string across the knotter. In operation, the piles as they are fed into position pull the string from he supply bobbins, the platen next descends upon the pile, and the needles simultaneously rise through the table, carry up the string, and pass it to the knotters. The knotters then turn on their own axes, grip the string below the retainer, and tie the knot. The retainers then rotate and grip the string, and the cutter cuts off the end coming from the knot. The platen then rises, and fingers 93 sliding on bars 94 and connected to the fingers 3 by rods 98 discharge the bundles. The fingers 93 slide on square shafts 94, Fig. 16, journalled at the ends. Slide blocks 95, moving on guides 96, engage the ends 97 of the fingers 93 to traverse them along, while leaving them free to turn with, the shafts 94. On the return stroke, the fingers 93 engage guides 99, which turn them clear of the new pile on the table until they reach their extreme backward position, when they are again drawn forwards by springs on the shafts 94, the motion being limited by pins 101. The fingers 99 during the discharging-stroke are lifted by the fingers 93. In a modified form of the machine, the segment wheels, quadrant plates, and ratchet mechanism are dispensed with, and a spur-wheel loose on the main shaft gears with a second wheel of half the diameter fixed to the second shaft 45, Fig. 3. A clutch piece on the main shaft is operated from the plate 17 and by cam mechanism on the machine frame to rotate the spur-wheel with the driving- shaft as required. In a preferable form of the gear for raising the platen 19, the upper cross-bar 53, Fig. 9, is dispensed with, and the lower bar is rigidly attached to the pillars, and is balanced by a counterweight 60. Links 63 are pivoted to the platen and to links pivoted to the frame, the latter links carrying rollers engaging the cam 48. Shields may be provided to guide the bundles into position for compression, and spring extensions may be arranged on the fingers 3 to engage with and be depressed by guide-strips fixed to the platen, so that the fingers will not be caught in the return stroke by the knotter shaft. All the parts of the machine may be operated from a single cam shaft, or the separate parts may be driven electrically and controlled automatically by closing the circuits in the proper order.
