IMPERIAL

PATENT OFFICE.

CLASS IS: Printing.

The present invention relates to innovations in typewriters, namely both on the general facility, as well as on a type moving device, which is particularly distinguished by its simplicity from other coristruction, as well as to a simplified paper feed device on the same.

A machine with the new facilities is shown in the accompanying drawing, in which

Fig. Ι a basic outline and

FIG. 2 follows the line 2-2 of FIG. 1 guided cut is.

Fig. 3 is a longitudinal section along the line 3-3 of Figs

FIG. 4 is a plan view of the type levers in the direction of that shown in FIG. 1 Arrow. . ".

Above the base plate carried by feet A ¹ is the sickle-shaped cover plate B, which carries the type levers D in special small bearing blocks C. E is a curved frame which carries the ink pad E ¹ and is held above the cover plate -B by stands e. The ink pad advantageously consists of a layer of felt e ¹ covered with muslin.

The key levers F are mounted radially in a known manner and each of them is connected at _ / ² by a rod / 'to the associated type lever D and guided in a slot in the curved guide plate A ^2.

E) he space lever G ² provided with key g is arranged on a shaft G mounted under the base plate in G ^1.

H are springs that push the key levers and the space lever upwards.

The shaft G also carries a lever / which, with a curved head plate P , engages under all key levers in such a way that when each of them is depressed, it is moved along with it, thereby causing the carriage to continue.

A rotatable shoe K is attached to the upper end of each type lever D at \ , to which the type head k is connected. This type head carries the types, for example three, k ¹ k ² k ^s , which are arranged in such a way that they lie exactly against the ink pad. .

A link L is also connected to each shoe K , the other end of which ^{engages the one arm C 1 of} an angle lever C ¹ C ² attached to the cirri bearing block C. A leaf spring c ^{l is} connected to the bearing block C, which presses on the other arm of the lever C ¹ C ² and gives way as soon as the shoe K with the type lever D has reached its horizontal position. The arrangement of an elastic link would be the-. serve the same purpose.

The compliance of the handlebar in the last stage of the movement of the type lever is necessary to avoid impure pressure which would otherwise arise at that moment the type of shoe is rigidly connected to .. the lever D and thus preventing it from turning.

M is the carriage in which the roller M ¹ , as usual with a fluted handwheel M ' ²

and rear derailleur Af ³ M ^ , 'is mounted. This carriage is guided in a slotted tube 0 through the intermediary of the rod M ^{5 carried by the arm 1} ; on the other hand, it is carried by the roller m ² , which is mounted in the arm m ³ and runs on the rail Q ¹ . On the rod to ⁴ connected to the carriage, the paper guides m ⁵ m ^e are arranged adjustably through the intermediary of the slide m ¹ , so that they can be moved on the rod m ⁱ , which makes it possible to adjust the paper guides depending on the width of the to descriptive paper against each other.

One paper guide m ^e is provided with the pawl m ⁸ which actuates the bell R and which is held by the pin m ^{9 in} such a way that it strikes against the arm r of the bell lever mounted ^{in r 1 as the slide moves forward.} However, when the slide is retreating, the pawl m ⁸ slides over the arm r.

S ¹ is the switching rod, which is connected to the slide and is moved further by the amount of a type width by means of the spring stored in the spring housing U ¹ \ by special switching teeth j ^l β both when the space lever is actuated and when each type lever is hit.

The slide is mounted in a frame P, which is pressed forward by a spring ν 'mounted on the rod V , with the mediation of a locking lever X and button w

equipped

Lever's WW can, however, be moved all the way back or in a middle position.

If, for example, three types are stored in each shoe, then the rearmost, middle or foremost position of the frame P, whether the uppermost, middle or lower Type of shoe in question comes to the service.

Claims (2)

'Patent claims: 1. A typewriter, characterized in that the types respectively. special type-wearing shoes (K) on the one hand (at %) are hinged to the type levers (D), which are rotatably mounted (at d) and influenced by the key levers by rods (f ^[ ) , and, on the other hand , are articulated to handlebars (L) , in such a way DAF's, the latter rotates about \ to coloring of the types in the upright position of the lever type, the shoe (K) during the lowering beating, wherein the link L is spring-mounted or on the arm of a lever beeinflufsten by Federe ¹ C ¹ C. ² 2. At the in claim ι. Typewriter marked the paper guides (m ^ m ^6), which (* m) are adjustably arranged on a carried by the paper slide bar and the width can be moved to be described, the paper according to the same of, said, a supply (m ^a) simultaneously Pawl (m ^% ) carries which, by means of a lever (r), causes the bell to stop at the end of the line. For this purpose ι sheet of drawings.
