Abstract: 17,626. Lake, H. H., [Richards, G. L.]. Aug. 11. Folding paper; addressing - machines; feeding sheets delivery - apparatus; rotary machines.-Relates to machines for folding, wrapping, and addressing newspapers, magazines, &c., and for assorting and delivering them in lots of predetermined numbers for despatch to different localities &c. Fig. 1 shows a side elevation, and Fig. 3 a sectional elevation, at right-angles to Fig. 1, of a machine without the assorting-mechanism. The papers are placed in piles on elevators consisting of platforms 43 carried by two pairs of endless chains on shafts 45. The platforms 43 on the inner runs move upwardly, and are in pairs on the same level, each pair forming a table for a pile of papers. Each platform has a side extension 43<1>, and these form side guides for the piles of papers. The upper shafts 45 are carried in movable parts 46', of the frames 46, adjustable by screws 46<11> to take up slack of the chains. The lower shafts 45 are driven by screw gear from a shaft 40 driven, through a clutch 42, by a belt 41 from a shaft 34 geared by change gearing 35, 36, 37 from a driving-shaft 32 rotated by a belt and fast and loose pulleys 30, 31 from a source of power. The top papers are fed off singly from the elevator, by fingers 58 on two slides 50, reciprocated on horizontal guide-rods by arms 53 of a shaft 54 rocked by an arm 55 connected by a rod 56 to a lever 57 operated by an eccentric on the shaft 32. The fingers 58 are pivoted, and have needles for engaging the paper, the ends carrying the needles being held raised by a spring latch during the back or return stroke of the feed-slides. At the end of each return stroke the latch is operated to release the fingers by a pin 64 on an arm 63, and the fingers are then drawn down by a spring into engagement with the top paper. They are raised by fixed cam inclines on the framing. The paper is fed between two rollers 67, 68 carrying rapidlymoving tapes 69, 70, extending round pulleys 71, 72, Fig. 5, by which they are driven. The tapes 69, 70 carry the paper under the first folding-blade 84, under which it is stopped by fixed stops. Sets of side tapes 79 keep the sheets in position laterally. The upper tape roller 67 is carried by long arms 73 on a rock-shaft 74 operated, by an arm 75 and cam 76, to lift the roller 67 and tapes as each paper is fed between the tapes. The wrappers are cut from a web 90 passing over a guide-roller 93 to cutting-rollers 94, 95, Fig. 5. The roller 95 has a cutting-slit 120, with which a blade 119 on the roller 94 co-operates. On each side of the blade 119 are sliding blocks 116 pressed outwardly by springs 118. The roller 95 may be provided with a plate for printing the wrappers, such plate being pressed by springs a little beyond the surface of the roller, so that it is inked by the roller 123. The rollers 94, 95 are geared together, and the lower one is driven by gears 112, 113 from a shaft 77 driven by chain and bevel gears 97 from the shaft 32. The chain-wheel 100 is loose on the shaft 77, and drives it through a clutch consisting of a disc fast to the sprocket-wheel and having a pin 103 adapted to engage a pivoted lever 105 on a disc fixed on the shaft. The lever 105 has a projecting part which may be engaged by an operating-lever 106 to stop the rotation of the shaft 77. The operating-lever 106 is connected by a rod 107 to an arm on a shaft 109 having another arm from which depends a tripping-rod engaged by the top of the pile. If no papers are on the elevator, or, if the papers are fed forward too slowly, the tripping-rod operates to stop the shaft 77. The wrapper passes between the tapes 70 and a set of tapes 96, and is carried by these under the fed paper under the blade 84, so that the two are folded together. The tape rollers 71. 72, and 125 are driven by gears 126, 127, 128, 129, 130 from the shaft 77. The roller 72 is lifted, to permit the wrapper to pass under it, by rods 133 and levers 132 rocked by cams 131. On the gearwheel 115 of the roller 94 is a crank-pin to which is connected a rod 135, also connected to an arm loose on the shaft 137 of the arms 63. The loose arm engages a pin on an arm fixed on the shaft 137. When the roller 94 is stopped by the disengagement of the clutch 103, 105, the arms 63 are held with their pins out of the paths of the latches on the feed-slides 50, and the feed of the papers is thereby stopped. The folding-blade 84 is reciprocated in guides 85 by an arm 86 rocked by an arm 88, rod 89, and an eccentric on the shaft 32. The paper and wrapper beneath it are carried down by the blade 81 between guide-rollers 140 into a space between guides 141, and are carried down between these guides, into position for folding by the second blade 150, by feeding-fingers projecting from a pair of endless chains, the fingers engaging in the folds of the paper. The chains are driven from a shaft 149 and shaft 77. In order that the fingers may be withdrawn from the folds of the papers at the proper times, the sliafts of the lower chain-wheels are carried in pivoted arms swung apart at intervals by cam arms &c. The blade 150 is reciprocated horizontally by a lever 158, rod 157, and eccentric on the shaft 32. It folds the papers through rollers 160, and presses them into pockets in an intermittently - rotating carrier 161 on a shaft 163. The pockets are formed by flat springs 165 and plates 164, the latter having curved extensions 175, which receive paste from a roller 176 in a paste reservoir. The carrier .161 is rotated by means of a disc on its shaft having radial slots in which a pin on a rotating spur-wheel engages. A pin on a camoperated lever engages in one of the slots to lock the carrier during each of its periods of rest. A flap of the wrapper projects from the pocket of the carrier, and is pressed down on to the pasted surface 175 by a roller 178 driven so that its surface engaging the surface 175 moves in the opposite direction, and acts to wipe paste from the part of such surface not covered by the wrapper flap. Paste is removed from the roller 178 by a scraper, and passes into a receptacle 254. The papers are removed from the carrier, and placed on endless feed-chains 190, by an ejector 180 reciprocated by a rod 184, lever 183, rod 182, and eccentric 181. The shaft 191 of the chain-wheels is driven from a wheel 167, and the chains have, at intervals, projecting teeth or lugs which engage and carry the papers along over a table and under the addresser 220. To hold the papers flat and compressed while on the chains, they are engaged between two sets of endless moving bands 195, 196. The front rollers of the bands 196 are in arms 207 rocked upwardly to permit each paper to enter between the two sets of bands. The pasted flap of the wrapper is pressed down on to the other part by a brush at the rear of the addresser 220. The addresser applies pasted address slips, which are cut from a strip passing from a supply reel over a feed-roller and a pasting-band running through a paste receptacle. The address slip is cut off and pressed on to the paper by an oscillating cutter blade operated by the eccentric 231, and the cutter blade operates an arm 240 of ratchet mechanism by which the strip is fed forward at each operation. The eccentric 231 is driven, through a one-revolution clutch, similar to the clutch 103, 105, from one of the chains 190. This clutch is engaged, to cause one operation of the addresser, by mechanism operated by each paper as it is moved along by the chains 190. The clutch 42 through which the elevator chains are driven is shown in Fig. 21. The pulley 260 driven by the band 41 is loose on the shaft 40, and is provided with a series of projecting pins 264 adapted to engage the arm 263 of a lever pivoted on a disc 262 fixed on the shaft 40. The other arm 266 of this lever engages a notch in a ratchet ring 261 surrounding the disc 262. The lever is normally pulled by a spring 265 into position to be engaged by one of the pins 264, but, when the ratchet 261 is engaged by a stopping pawl 267, it is moved on its pivot out of the path of the pins, and the shaft 40 is stopped. The pawl 267 is operated by a rod 268 connected to an arm on the tripper shaft 109. When the elevator feeds the papers up too rapidly, the tripper is raised and rocks the shaft 109 to cause the pawl 267 to engage the ratchet 261. In order to prevent the papers from adhering together and more than one being fed at a time by the feeders 58, a blast of air is directed on to them from a perforated pipe connected by a pipe 271 to a fan or blower 270 driven by a belt 273. The assorting- mechanism which may form a part of this machine is shown in plan in Figs, 29 and 30. It is located beneath the delivery end of the conveyer chains 190, which deliver the papers into a shoot or pocket 293, from which they pass into one of a series of mail bags or other receptacle 283 on a rotary carrier 282 on the shaft 281. When a bag 283 has received the required number of papers, the lower end of the pocket 293 is closed by a shutter 295 pivoted on the shaft 281, and the carrier 282 is rotated to bring the next bag 283 under the pocket 293 to receive the papers. This receiving-apparatus is controlled by a chain 296, having projecting pins 307 on some of its links, the number of links from one pin to another corresponding to the number of papers in one lot. The chain is fed, one link for each paper addressed, from a supply spool to a winding-spool, by a sprocket feed-wheel 300 rotated by ratchet mechanism. Each pin 307 engages a pin 309 on an arm 308 on a shaft 310, and moves an arm 311 on the shaft 310 into the path of pins 313 on arms on the shaft 192 of the conveyer chains 190. The arm 308 is thereby moved further, and a pin thereon co-acts with a latch 316 on the hub 315 of the shutter 295, to release the shutter and permit the spring 319 to rotate it under the pocket 293.
