Abstract: 1620. Faris, I. Jan. 20. Index type - band machines for printing tickets. -A machine for printing railway tickets &c. comprises index - set typebands for printing variable matter on the tickets and on recordstrips. The band or chain 61, Fig. 3, for printing on the tickets and on a record-strip 127 passes over rollers 63, 64, and is set by a handle geared to the shaft 67. The roller 64 is tensioned downwards by a spring. A band similar to the band 61 is provided for printing on record-strips in connexion with a numbering- mechanism. Alining for impression. -The roller 63, Fig. 3, is formed with recesses adapted to receive spring- pins 70. The roller 63 is also formed with recesses to receive the hinge-pins of the links of the band or chain. Paper - supports. - The ticket is received by a spring - mounted support 41, Fig. 3, which is formed with an aperture 60<a> through which the types on the band can pass, the support being pressed upward by springs 42 and guided by pins 43. Hammer-impression arrangements.-The platen 44<a>, Fig. 3, that presses the ticket on to the support 41 may be forced with a spring - pressed bottom 112, which normally bears lightly on the support 41 ; when printing is to be effected, the platen is depressed by a reciprocating cross - head 52 operated by link-work from cams on a crankoperated shaft 4, a spring 53 transmitting motion to the stem of the platen, and a sleeve 58 being provided between the cross-head and nuts 59 on the stem to permit adjustment and prevent wear of the cross-head. The platen may be provided with printing-surfaces if desired. Ink-ribbon mechanism.-(1) An ink-ribbon 169, Fig. 3, for inking the types 61 and types 40 for permanent matter, passes from a spring-braked drum 170 and is led over the printing-surfaces to a tensioning roller 178 mounted on weighted bellcranks, and to a winding-drum 171 driven by a ratchet gear and a cam on a shaft driven by chain gearing from the shaft 4. (2) An inli-ribbon 476, Fig. 25, for use in connexion with the total-printing mechanism, passes from a spool 477 over guiderollers and between record-strips, and is wound upon a spool 480, which is actuated by a ratchetwheel 482 and a double pawl 483 on a reciprocating link 473. The spool 477 is fitted with rightangled slots 488 in its side, and a pin carrying a roller 490 is normally maintained by the wound ribbon in a recess in the axle of the spool. When the ribbon on the spool 477 gives out, the pin of the roller 490 falls down slots 488, and as the roller rotates it pushes back a spring-controlled arm 494 fitted with a pawl 498, which after the roller passes the arms returns and forces a bar 486 to the left. A projection 484 then engages the right-hand edge of a U-shaped slot 485, and the pawl is reversed so as to engage ratchet 481. Detents hold the rod 486 from moving except as described, and pins engaging slots guide the bar in its horizontal movements, these slots being undercut to prevent movement of the bar in the normal actuation of the pawl 483. (3) The ink-iibbon for the item - printing mechanism is similarly actuated except that the bar similar to the bar 486 is provided with studs and reverses the actuating- pawl by engaging recesses on opposite sides of the pivot of the pawl.
