SU33968A1 - Writing machine - Google Patents

Description

In the work of each typewriter, the printing process itself usually consists of two main points: the filing of the corresponding mark on the line and the stroke to imprint this mark on the paper. In existing machines, this is accomplished by the same mechanism, which with the help of a system of levers produces and feeds the signs and performs a blow, and such a mechanism is available for each sign.

In the proposed typewriter, feed and punch are performed by separate mechanisms. The printing of the printed mark is made using a rotating hollow drum (poTOJpa), which has 3HS (Kff. Ozar) on the circumference, in special sockets, which are made by a special striker, the latter can strike any sign, with a drum, alternately passing under it.

The drawing shows a writing machine in schematic form.

The proposed writing machine consists of a rotating drum / equipped with two rows of openings for spring-loaded lettered rods. On the axis of the drum, the gear wheel b ,, is attached to the index wheel of the drum 7 interlocking with the gear wheel 5 on the axis 7. The gear 5 engages with the internal tooth (43). ;

The handwheel j of the manually rotated jaw is set to place the letter under the striker 2, controlled by the keyboard lever 3. To set the striker 2 under the head letter of the drum / serves. cam part // and keyboard lever / 2. The spider mechanism 9, 10 and the trigger lever 13 are used to move the machine to the letter distance.

To set the machine in motion, it is moved to its original left position; at the same time, the spring 10 is twisted and thereby accumulates energy for further, independent movement to the right. Then the handwheel is rotated with the right hand, as a result of which the teeth 5 and (5 are rotated and the drum / and pointer 7 are set in motion. the required mark is pressed on the lever 5, which, in turn, presses the firing pin and a blow to the letter is received, the latter jumps out of its slot and makes an impression on the paper through the tape. the pawl of the mechanism P neither typewriter, moves the whole cart on one letter right. Simultaneously with this, the printed letter when POM1DI springs returns

back to your nest. Further pbvto, p is the same with another sign. .

Dp of receiving large capital letters, the drum shaft with the help of the device, which represents a special lever, moves to the left, the supply itself, under the striker next to a large font. At the same time, the pointer is moved accordingly.

This machine can be electrified by inserting a small electric motor into the mechanism for rotating the rotor & and electromagnets for the percussion mechanism and motion control of the machine.

Applying Latin and Greek alphabets on the bukvoneschy drum, except for Russian, it is possible to produce technical texts with formulas. Alphabets can either be placed on the same drum or have interchangeable drums.
