Abstract: 10,323. Nowak, E. May 6. Type - writers.-The types are in several parallel rows on a segment 1 attached to a shaft 3 mounted to rotate and slide longitudinally in ball-bearings 2, to bring the proper type opposite the hammer 14 when a key 9 is depressed. The key levers 11 are pivoted at 10 and each has two projecting arms 12, 13 for engaging rods carried by pairs of arms on the shaft 3. A spring 4 returns the sector to normal position. The arms 12 rotate the shaft 3, and the arms 13 engage the rod and stop it in the proper angular position. The shaft 3 is moved longitudinally to bring the proper row of types into printing position by two arms 52 engaging the opposite ends of the shaft, and projecting from a lever 50 on a central vertical pivot. Two other arms 53 project laterally in opposite directions from the lever 50, and each arm is engaged by a spring pin 58 on a bent lever 54 pivoted at 10. The levers 54 are at the opposite sides of the machine, and each carries a transverse rod 55 projecting under half of the key levers 11. The hammer 14 is opposite a central line or space on the segment 1, and there are two rows of types on each side of this space. When a key 11 is depressed, one of the arms 53 is moved against a stop 60 and the shaft 3 is moved longitudinally to bring one of the inner rows of the types opposite the hammer. To bring either of the outer rows into printing position, a shift key lever 64 is depressed and a projection 66 on this lever depresses the stops 60 out of the path of the arms 53, and the shaft 3 can then move further. The hammer 14 is pivoted at 15 and is connected by a short link 17 to a lever 19 pivoted at 18 and having a roller 20 running on the teeth of a crown-wheel 21. On the shaft of the crown-wheel is a pinion 22 in gear with a rack 45 on the carriage 43, which is drawn along by a spring drum. On the lower edge of the crown wheel are ratchet teeth 25 engaged by an escapement anchor operated by a link 28 connected to an arm 29 on a universal lever frame 30, having two bars 31, 32 extending over all the levers 11. The carriage runs on rollers 41, 42. At each depression of a key, the escapement is operated and the carriage is fed and the hammer operated. The space key lever 37 has a projection 38, which prevents the fall of the hammer when this key is depressed. The rack 45 is pivoted and may be depressed to disengage it from the pinion 22 by a hand-lever on a shaft 49 having a finger engaging the rack. In order that the key levers may be moved further down, after their projections 13 engage the rod 8, to operate the hammer after the segment has been set, one arm of each pair is loose on the shaft 3 and is connected to the other arm by springs strong enough to overcome the spring 4. After the setting of the segment further depression of the key extends these connecting-springs, compresses the springs of the pins 58, and rocks the anchor far enough to release the wheel 25. The segment may be rocked in one direction by one half of the keys and in the opposite direction by the other half, the rods and the arms 12, 13 being arranged accordingly.
