This rack is engaged by a gearof one arm with its operation explains the wheel 37, rotating with the type-wheel or its 56 other. Shaft 16 is preferably formed of two sleeve 29. Springs 38, hitched to a suitable "too point, say a bar 18, tend to return or hold the type raised or away from the platen and return the driving-levers 19. The rack-race 35 is shown with an arm or segment 44, Fig. 2, and a locking-bail 43 engages this arm to lock the type wheel against tilting toward the platen. When a key-lever is struck, it raises its corresponding pin 18 and swings crossbar 18 with the respective arm 19 to rotate the driving-sleeve 22 with shoulder-piece 21 and rotate segment 24 and type-wheel 1, the gear-wheel 37 rotating with such type-wheel. This gear-wheel slides rack 36 with stop 39 until the latter is arrested by the pin 18,

raised by the actuated key. Rotation of the type-wheel is now stopped. The pin 18 contin uing to press onto bar 18 and the key-lever having lifted the locking-bail 43 out of hook 44, the frame 30 is tilted to bring the typewheel to the platen for a printing stroke, the tubular shaft 22 and rack-race 35 rocking with the frame.

The spacing arrangement maybe of any suit-able kind. In the drawings is indicated the well-known dog 46, with rack 47 on the carriage of roller 2, the dog being actuated by arm or bail 50 at escapement-shaft 51 and engaged by or extended over the key-levers. By omitting a pin 18 the corresponding keylever becomes a spacer and will actuate the feed-dog, but not the type-wheel.

The ribbon or inking device is not shown, as any suitable in k-roller will do.

The case-shift movement of wheel-shaft 27 can be done by a lever-arm 55, Fig. 2, fulcrumed at 56 and having an arm 58, Fig. 1, engaged by or reaching over one or more shift-keys. The keys thus act directly on the shift-lever, so that the construction is simple.

Secured to a suitable part of the machine is an arm 48', Fig. 2, and when the type-wheel is printing the toothed disk 48 engages this arm or born 48, Fig. 7, to further lock the type-wheel to insure accuracy.

The levers 19 when at rest or in normal position rest against screws or stops on frame 30, and a stop 66, Fig. 2, limits the upward swing of the type-wheel-that is to say, the backward swing of arm 41. These stops are practically made adjustable for obvious reasons.

The type-wheel shaft and the driving-shaft 22 are shown at an angle to one another, the type wheel being in convenient striking position to the platen and the driving-shaft having its arm 23 extended toward such typewheel shaft.

As seen in Fig. 5, the driving-levers 19 when at rest hold the shoulder-piece or slotted bracket 21 in what may be called central position or in the position from which the shoulder-piece is to start rotating to the right or to the left. In other words, the piece 21 is .made to extend rearwardly, by which means either of the oppositely-located driving-levers both on its driving and return movement will positively drive and positively return the shoulder-piece or contacting part 21, with which said levers contact, and which contacting-piece moves the type-wheel-driving gear or segment 24 or the rotating member 23, carrying said segment, and which segment is curved or centered about the center 28, about which member 23 rotates. The pivoted key-levers, having their inner ends or the pins 18 of said inner ends arranged under the forward ends or bars 18 of the levers 19, are in convenient position to swing said levers to strike shoulder 20. The typewheel-carrying sleeve 29 being mounted on the rear upper part of shaft 27 allows play to the latter and to the lever 55 for case-shifting, and the rack-driving gear at the front of this sleeve 29 is in convenient position for the application of rack 36.
