Abstract: 18,634. Fairweather, W., [Sheldon, E. P., and Story, W. B.]. Aug. 29. Addressing-machines. - In a machine for addressing envelopes and other wrappers, the paper for forming the wrapper is fed from a roll 95, Fig. 1, to continuously-driven feed-rolls 97, 98, actuated by a friction disc 141 which is pressed outwardly by a spring on a shaft 142 to engage with a friction wheel 143, driven through gearing 145. 146, 148, 149, 129 from the main shaft 90. It then passes around a roller 99 and a roller 100, the bearings of the latter having springs 101 to take up the slack caused at intervals by the intermittent feeding-apparatus driving the roll 108. This feeding-device, which pulls the paper past the roller 102 through devices for printing addresses and punching at 162 and over a roller 104, is driven from the main shaft 90 by gearing 129, 128 actuating a variable crank 127, which drives a rod 124 having a rack at the outer end, gearing with a pinion 120 loose on the shaft and driving a spar-wheel 115 intermittently through a ratchetwheel and pawl. The wheel 115 drives through gearing the rollers 107, 112, which support and drive the roll 108 of addressed wrappers. The bearings 110 of the roll shaft 109 slide on pillars 111 at each side of the machine. The type representing the names and addresses is set up in groups or lines, with spaces between, in long galleys 35 Fig. 3, which are fed into the machine at the front end, and pass under inking-rollers 75 in a frame 76 at the front end of the main fiame 11. These rollers are normally rotated and inked by the feed and distributing roller 77, which gets its motion from the driving-pulley 180 and grooved pulley 179 through driving-belts 89, 86, 83, 79. When a galley is introduced, it bears on the roller 174, Fig. 1, and, through the levers 175 and links 177, lifts the frame 178 carrying the rollers 77, thereby allowing the rollers 75 to roll on and ink the type in the galleys. The galleys are guided by bars 14, the left-hand galley being arrested by the end of a sliding bar 16 (shown broken in the plan, Fig. 3, where the upper part of the machine is removed), and the right - hand galley by a bar 17. The driving-pulley 180 is loose on the shaft 90, which it drives through a pin 190 engaging a spring- controlled pivoted stop 189 on the shaft, normally held out of gear with the pin by a finger pivoted on a shaft, having a lever actuated by one end of a rod 21. When this roll is pulled at the front of the machine, it moves the finger out of engagement with the. stop 189, allowing the shaft 90 to be driven, and at the same time releasing a brake on the shaft. It also shifts the bar 16 out of the way of the left-hand galley through the links and levers 20, 19, 18, allowing that galley to be fed forward by one of the pawls 22. A spring connection between the lever 18 and the bar 16 allows the bar to be pulled out of the way of the galley by a hook 199, without starting the machine, and also allows the machine to be stopped if necessary while the left-hand galley is being fed through. The feeding-pawls 22 are mounted on reciprocating slides 23 actuated through links 19 and cranks 26 from a shaft 27 reciprocated by an arm 29, Fig. 1, having a tumbler at the end engaging with a cam-race 30. Their positions are so controlled by eccentric pins 25, Fig. 3, actuated through links 50, 51, 52, that only one galley is fed forward at a time, the pawl engaging with the sets of type and feeding them forward one at a time. Pawls 37, 200 prevent the galleys from returning. When the left-hand galley has been fed through, the end 45 of the galley engages with the pawl 37, and pulls it forward, thereby shifting the position of the pivoted cross 40, controlled by a spring 53 ; the pawl 37 is then disengaged from the ridge 45 by a pin sliding on the inclined part of the pawl. By shifting the cross 40, the left-hand pawl 25 is put out of, and the right-hand pawl into, engagement with their respective galleys, and also the bar 17 is shifted from in front of the right-hand galley to behind the left-hand galley, where it holds another left-hand galley in readiness to be fed when the right-hand one is finished, and so on, each side being used alternately. The used galleys are pushed by those in operation on to rollers 15<a> carried by levers 55 pivoted on a shaft 60, and supported at the other end by levers 61, Fig. 1. When the galley has been pushed sufficiently far, it engages stops at 66, and thereby, through the links 64, pivoted levers 63, and links 62, displaces the levers 61. The levers 55, being released, lower the galley on to a travelling band 68 passing over pulleys 69, 70, and the galley is thereby returned to a table 71 at the front end of the machine. The levers 55, relieved of the weight of the galley, are returned by springs 72 to their normal position, as are also the levers 61. The printing is effected by spring-controlled vertically-reciprocating platens or blocks 155, which press the web in its stationary periods on to the inked type groups in the galleys. The paper is also perforated with two or more holes, for use in a wrapping and folding machine, by punches working in the hollow frame 162, and actuated by a spring 165 adjustably carried by the bar 152, which also carries the blocks 155. The punchings are cleared out of the hollow frame 162 by a blast of air from a bellows 168, worked by a lever 171 and crank 170 from the shaft 27. The bar 152 receives a vertical reciprocating motion through the side rods 151 from cams 150 on the main shaft 90.
