Abstract: 15,651. Marks, E. C. R., [Montague Mailing Machinery Co.]. July 5. Addressing - machines. - In an addressing- machine of the kind in which the magazines or the like to be addressed are traversed across the line of travel of the address - plates, the magazines are fed to the printing position by fingers 4 on one set of continuously-moving chains 1, and, after a momentary stop, are removed by another set 6 having fingers 9, which carry the magazines against pivoted fingers 12, whereby they are inverted as they are taken by delivery chains 11. The address - plates are fed across the printing position by an intermittently-actuated chain 25 from a hopper 29. Means for stopping the machine in case an address-plate sticks, or when no magazine is fed by the chains 1, are provided. The platen 13 is reciprocated through links 19 and levers 18 from a rock-shaft 17 actuated from a shaft 93 through a clutch, which is normally out of operation but is coupled by a magazine when fed along the chains 1, lifting the finger 95 and thereby actuating the clutch-operating lever 94. The address-plates travel in a path across the path of the magazine, and have depressed margins engaging with grooves in the table 5 to guide the plates. One of the grooves is made sufficiently deep to carry the driving-chain 25, which has lugs 28 to engage one margin of each plate, the plates being pressed down on this side by a spring-pressed strip 46. On the other side the plates are held down at the printing position by a bevelled guide-wheel on a vertical spindle mounted in a spring-pressed frame. The chain 25 is driven intermittently through a shaft B on which a free-wheel clutch 93 is mounted. Round the loose part of this clutch a chain 82<1> is partly wrapped, and attached at the other end to a spring 82. Another chain 83 is wrapped round the loose part in the opposite direction, so that when a lever on the shaft 17, to which the chain is attached, pulls the chain 83 downwards, the spring 82 is extended, but on the upward movement of the chain 83 the spring 82 turns the clutch, and through the pawl 92<Î> drives the shaft B unless an addressplate sticks and thereby prevents the movement of the clutch. In this case, the chain 83 slackens and allows two portions of the operating-lever on the shaft 17 to move relatively to each other and close an electric circuit, by which the machine is stopped. If it is desired to print more than once from each address-plate, a pawl G<1> is turned into engagement with a ring a<2> mounted on the loose portion of the clutch 93, and having a recess in which a roller a<5> on the tail of the pawl 92<Î> normally passes. If, however, the ring a<2> is held by the pawl G' while the clutch is being set, then, on the return movement of the loose clutch portion, the pawl 92<Î> does not drive the shaft B until, by repeated operations, the recess in the ring a<2> is brought into position for the tail of the pawl to drop into it. Two series of notches may be provided on the ring a<2> to engage with either of two pawls G' to cause double or treble printing of each address. The plates after printing are delivered into a curved trough 47 by which the pile is turned from a vertical into an horizontal position. The ink ribbon, as shown by a dotted line in Fig. 2, passes from a spool 24 over guide-rollers between the magazine and the address-plate to a spool 21<1>, and preferably is operated by mechanism described in Specification 2515/12, [Class 100(iv), Typewriters &c.].
