Abstract: 128,490. Fraine, H. G. de, and Chamberlain, S. B. Oct. 25, 1918. Record-controlled type-wheel machines.-In a line-printing machine, particularly for addressing envelopes, post cards, &c., of the kind in which a series of type-wheels are set differently by rack- and-pinion mechanism, controlled by a perforated record-card which is arranged over a perforated register-plate, the racks are moved across the record-card and are arrested bv projections on the racks passing into the holes in the register-plate that are exposed by holes in the card. The typewheels 4, Fig. 1, provided with types 5, gear with racks 8 which run on rollers 10, and are formed at the front with a projection 9 for engaging the record-card. Fins 11 on the racks engage grooves in the roller and a comb 12. The type-wheels are mounted loosely on a shaft 6 and are separated by plates 54 which are threaded on rods 55 and are separated by collars 56. The record-card is placed on the perforated register-plate 1, register being ensured by the engagement of pins 3, Fig. 3, with holes in the card. One card is employed for each line of the address. The racks are drawn across the card bv a bar 13 which is formed with bevelled recesses 14, Fig. 5, for engaging projections 15 on the racks. When the projection 9 on any rack reaches a perforation in the record-card. the projection drops into the register-plate and the associated type-wheel is arrested. After the impression-mechanism, described below, has been operated, the bar 13 returns and restores the racks to the normal position, the racks that have dropped being picked up by the engagement of a bevelled edge 22. Fig. 5, on the bar with bevels 23 on the racks. The bar is operated by camlevers 58, formed with slots for engaging pivoted blocks 59 at the ends of the bar. Alining for impression.-An alining-bar 17, Fig. 1, for engaging the gear-teeth 7 on the typewheels is secured to levers 18, connected to an arm 20 which is depressed by a spring 21 and is raised by a rod 61. Platen-impression arrangements.-An impression-roller 16 is mounted in a frame 24, secured to a shaft 25 which is rocked by gearing 30, 29 operated by a rod 26. Envelope and card feeding arrangements.-The envelope &c. is held in contact with the platenroller 16 by endless bands 33 which pass over rollers 31, 32. Line-spacing mechanism; platen rotation for blanking. The platen-roller 16 is rotated to feed the envelope &c. into positions for receiving the successive lines, usually three, of the address, and is then reversed to discharge the envelope by the following mechanism. A pinion 34, Fig. 3, on the platen-roller engages a pinion 35 which is rotatable on the shaft 25 and is secured to a sleeve 36. formed with or secured to a nut engaging a screw 37. The screw is feathered on the shaft 25 and is reciprocated intermittingly by means of a sector 40, on a cam-operated rock-shaft 42. When the frame 24 is in the vertical position, an envelope is placed in or fed into the grip of the tapes 33 and, after the type-wheels have been set, the frame descends and the initial feeding and the printing of the line are effected. For printing the second and third lines, the frame 24 is not raised to the vertical position, and the feeding or line-spacing movement of the platen-roller is effected during the rising of the frame. When the frame again rises to the vertical position the envelope is discharged. Roller inking-arrangements-The type-wheels are inked, after each impression, by means of a roller 50, Fig. 1, which is carried by oscillating levers 51 and transfers ink from a roller 45. Ink is supplied from a trough 43 to a roller 44, and is transferred to the roller 45 by a roller 46 carried by oscillating levers 47.
