Abstract: 17,083. Lee, U. G. July 25. Addressing-machines. - In a hand-operated addressing machine of the kind employing separate address - plates and an ink - ribbon, the address-plates are fed by an endless chain and the ink-ribbon and chain are operated automatically by the movements of the impression arm. Means are provided by which two or three impressions may be made from any one addressplate. The address-plates are fed from a hopper 10 by an endless chain 13<Î>. The chain-wheel 14<Î> is fixed to a shaft 15<Î>, which is intermittently rotated by a ratchet-wheel 19<Î>, Fig. 5, fixed to the shaft 15<Î> and operated by a pawl 18<Î> carried by a drum 17<Î> oscillated by the movements of the pivoted impression arm 4<Î> through the medium of an arm 22<Î>, slotted arm s, shaft t, and gearing u. The ink-ribbon a extends under the table 1<a> at the impression point and then up over angular portions x of the table and again under the table through slots y to spools d fixed to shafts carrying ratchet-wheels 71, 72. A pawl 70 operated by an eccentric pin on the pivot shaft 3x of the impression arm may be engaged with either ratchet-wheel so that the ribbon may be fed in either direction. To permit duplicate or triplicate impressions to be made from any addressplate, a controller ring 60, Figs. 4 and 7, is provided having a notch 61 and two rims 25<Î>, 24<Î> having two and three peripheral notches respectively. Normally the notch 61.registers with a tooth of the ratchet 19<Î> and the controller ring oscillates with the drum 17<Î> through the medium of a friction block 20. By placing a detent 64, Fig. 1, in engagement with either of the rims 25<Î>, 24<Î>, the ring 60 is displaced relatively to the ratchet 19<Î> so that the unnotched periphery of the ring holds the pawl 18<Î> out of engagement with the ratchet and no movement of the chain takes place on the next upstroke of the impression arm. After repeated operations, the notch 61 and ratchet tooth are again brought into registration and the chain is again operated. A feed of the chain takes place at every second or third operation of the impression arm according to whether the detent 64 engages the rim 25<Î> or the rim 24<Î>. The chain may be operated by hand independently of the impression arm by means of a knob 8<Î> on the shaft 15<Î>, a spring- pressed feeler roller e and notched disk f indicating when the address-plates are at the printing position. A spring-pressed brake-roller 21 is provided to prevent the plates being thrown past the printing position by the chain. The impression arm 4<Î> is bent laterally to provide a free passage across the table for the work. Specification 14,464/13 is referred to. The Specification as open to inspection under Section 91 (3) (a) comprises also the machine shown in Fig. 2 (Cancelled). The plates are fed by a pair of chains 12, the driving-shaft 15 of which is intermittently actuated by a ratchetwheel 19, Fig. 3 (Cancelled), loose on the shaft and operating a pawl 18 mounted on a carrier 17 splined to the shaft. The ratchet-wheel 19 is oscillated by means of a gear-wheel 21 and toothed segment 22 carried by the pivoted impression arm 5. The ink-ribbon extends transversely across the table between spools 35 operated through bevel-gearing on a shaft 37, which is intermittently rotated by ratchet gearing operated by connexions 39, 40 from the impression arm. To permit duplicate or triplicate impressions to be made from any address-plate, controller disks 24, 25 are frictionally held against the opposite sides of the ratchet-wheel 19, and the pawl-carrier 17 can be moved along the shaft so that the pawl 18 engages the ratchet-wheel only or the ratchet-wheel and either of the disks 24, 25. The ratchet 19 has four similar teeth and the disk 24 for duplicate impressions is provided with two deep notches 30, Fig. 6 (Cancelled), and two shallow teeth 31. When the pawl 18 engages the ratchetwheel and the disk 24, feed of the chains only occurs when a deep notch 30 and one of the ratchet teeth are in register at the beginning of the upstroke of the impression arm, and this occurs at every second operation of the impression arm thus giving duplicate impressions. The disk 25 for triplicate impressions is provided with two deep notches 32, Fig. 7 (Cancelled), and four shallow teeth 33. To obtain more than three impressions from any address-plate the toothed segment is disconnectably attached to the impression arm by a screw 34. The pawlcarrier 17 is held in its adjusted position by the engagement of notches 28 in the member 27 with a plate 29 on the machine frame. This subject-matter does not appear in the Specification as accepted.
