Abstract: 24,085. Addressograph, Ltd., [Addressograph Co.]. Nov. 7. Addressing-machines.-The machine is intended to print addresses and other subject-matter from printing-plates 1, Fig. 1, carried by a moving chain 26 from a magazine 10 past inking-devices to a position below a platen 105, which presses the article to receive the impression against the type. The plates 1 then pass into a tray 4, from which they are returned at a future time into the magazine 10. The whole machine is actuated by a footlever 30, pivoted to the frame at a point about midway between the pivot 80 and the upper end. The oscillation of the lever 30 actuates the carrying-chains 26 intermittently through a link 32, the lever 33 on the shaft 34, and the lever 35 with the spring-controlled finger 36, engaging with studs 37 on one of the chain-carrying sprocket-wheels 28 fixed on the shaft 29. The sprocket-wheels are locked in position by spring-controlled arms 42, 46, pivoted at 43 and engaging with opposite sides of one of the studs 37 ; in some cases, one lever, with a V-notch into which one of the studs 37 drops, is used instead. In either case, the wheel is unlocked for further movement by the lever 35 in its lowest position engaging with and depressing the locking- devices. A spring-controlled finger 49 prevents the finger 36 from engaging with a stud 37 until the previous stud has been moved its full distance. The chain 26 has links at intervals, provided with projections 62, 63, the first of which pushes forward the lowest printing-plate in the magazine, while the second prevents the next plate from being fed before the proper time. The chains are supported in suitable guides, and each plate is inked in succession, preferably at the next two stopping- places, by two pads 70, carried by a bar 82 and rocked between the position shown, where they are in contact with stationary inking-pads 71, and a position in contact with the plates, which pass underneath the pads 71, by levers and links 74, 76, 77, 41, 79 actuated from the foot-lever 30. The movement of the pads 70 is in a substantially vertical direction when near either the pads 71 or the type-plates. The plates then pass under a cover 87, pivoted and secured to the framework by spring- pressed latches 88, and having an opening beneath which the plates come to rest. A spring-controlled, sliding pad carried by a rod 91 is brought over the plate, when it is in this pusition, by the backward movement of a pivoted arm 93, actuated by a roller 96 on the lever 35, and is finally depressed on to the type by rollers 100 on levers 101 engaging with cam-pieces 102 on the springy, curved extensions 98 of the pivoted cover 87. On the return stroke, the pad is removed, and the platen 105, moved through the levers 109, 110, 112, 108, and adjustably mounted on the pivoted lever 106, at the same time depresses the envelope, which is laid on the cover 87, on to the type. The plates then pass to a tray 4, between the pivoted packer 116, actuated by a link 118, and the follower 5. A pivoted support 113, held in a tilted position by a catch 115, is provided for the tray 4. When this tray is full, the printing-devices may be again discharged into the magazine 10, which is pivoted at 11, Fig. 9. In doing this, the front 12, Fig. 9, of the magazine is first swung back on its hinges 13, 14. The rear end of the tray is inserted into the bottom of the magazine, and both are tilted into the position shown in dotted lines against the pressure of a pivoted, spring-controlled catch 18. The tray is then removed, the door 12 being still held back by the grooved parts of the pivot 13 engaging together. But, as it is being brought back to its upright position, the pintle 13<1> strikes the top of the catch 18, and lifts the door, against the action of the spring 15 attached to the pintle 16. This spring, which has a torsional as well as a tensional strain, then automatically closes the door 12 as the magazine is lowered. The printing-devices having been discharged into the magazine, the follower 5 is returned to the front end of the tray either by hand, or as described in Specification No. 4382, A.D. 1904.
