Description

The proposed writing machine is an improved machine, described in the main author's certificate No. 37716. Improvements consist in the fact that the letter E drum moves only in the horizontal direction, and for the production of the impression the segment roller moves in the vertical direction and presses against the drum. In addition, the inking apparatus and the device for adjusting the line spacing have been changed.

In FIG. 1 shows a general view of the car; FIG. 2-view of the segmental shaft; FIG. 3 — device for setting the step of moving the carriage; FIG. 4 shows the connection of the machine with the drum, the inking machine and the segment shaft; FIG. 5, b, 8-colorful apparatus and its location near the drum; FIG. 7-washing machine; FIG. 9 is a device for adjusting the line spacing.

As can be seen from FIG. 1, the drum is fixedly mounted on the bar 6, with which it is easily removed from the JOO's tongues, where it snaps into place (16)

a movable position, with the WS 708 being inserted through the slots from above. Two drums can be simultaneously mounted on one bar, i.e. one can write simultaneously with two fonts or two pins of the same font.

On the drum 7 in three rows, the letters and signs of the IOL Keyboard 7Y2, are placed. consisting of a devil with a key, is located in six rows and corresponds to three rows of symbols on the drum.

Register translation, respectively, to the number of characters on the reel is performed automatically, simultaneously with pressing the key of the corresponding letter, as described below. The letters on the drum are one with it, since they are cast simultaneously. The drum, as well as the platform on the shaft 2, on which the impression is obtained, is calculated on the maximum skittle, accepted for this machine.

With a size of 16, the radius of the drum with spaces between the letters of 100% of their width and with 90 signs is 3 cm, and with a size of 28, respectively, 5.5 cm. The width of the drum / with a size of 16-4 cm

and with a size of 28-6 cm. All signs on the drum are spaced apart from each other at the same distance, counting from the center of the sign, and all the drums for all fonts and pins for a given machine size are the same radius and the same width for the maximum size.

The drum / in the sinuses WO is reinforced in such a way that, while remaining completely stationary for movements in the vertical plane, it allows the following two types of movements: rotational, allowing you to install the desired letter against shaft 2 and in the horizontal plane, allowing you to install q characters W1.

The letters W1 are mounted on the drum / in such a way that they come against the front edge and not against the middle of the shaft. Imprinted letter is separated from the edge of the shaft no more than the height of half a point. Rotational motion of the drum passes when the / 02 button is pressed, through the transmission mechanism from the rods 103, J04, onto the gear 105, located on the rod 107, which is a continuation of the rod 6. This provides a fixed opposition to the shaft 2 of the letter indicated on key. The transmission mechanism is two-way, so that the rotation of the drum occurs either to the right or to the left, which shortens the time of the first run and accelerates the work. The sinuses 100, in which the ends of the rod 6 are fixed, are located in plates 108, ending with soft iron cylindrical rods 107, moving in electromagnets 109, 109. At the end of the rod 107 closest to the keyboard, the gear shaft 105, whose rotation is from key 102 gives the drum a turn / around the axis. When the key 102 (Figs. 1 and 4) is pressed, even before the gears 104-105 start to move, the current on the electromagnet 109 (front or rear) closes and the rod 107 is drawn into it and brings the plate 108 to the electromagnet 109, thereby providing the corresponding movement drum and the installation of the desired number of signs against the shaft 2.

The contact of the shaft 2 with the drum / after installation it is carried out

The following mechanism: the key 102 (Fig. 4) moves in the cylinder 52. During the movement of the key 102, there are two spring pins 16 (above) and 17 (below). When pressing the puff 77, contact pads closing the current only in one direction close the current to the electromagnet 115, lifting shaft 2. To the handle 22 of the shaft 2 on both sides there is attached on the coupling rod 112 with a fork 113, to which an iron cylinder 114 is attached (FIG. 2 and 4). This cylinder walks inside the electromagnet 115, closing through the bolt 77. Razviliny 775 moves to the runner x electromagnet 775, which provides a solid position for the entire device.

When the current closes when the key is pressed after the installation of the letter 101 against the shaft 2, the electromagnet 775 engages the cylinder 77 and lifts the shaft 2 to the drum 7, and the shaft takes a step, respectively, in size and font, as explained below.

By adjusting the strength of the current, you can provide the desired force of onslaught. The shaft is separated from the drum at a small distance, so that the pressing is quick and gentle at the same time.

Returning the key to its original position, which occurs when you remove your finger from it, brings the entire system to its original position.

The movement of the axis 22 of the shaft 2 (Fig. 1) is associated with the movement of the roll 38 of paper or other material of the printing mechanism.

The roll pitch for creating distances between the rows is provided by the following mechanism: the roll 38 (Figs. 1 and 9) springs back and is restrained in its movement by the dog I which goes to the electromagnet 725. The current passing through the electromagnet is controlled by a rheostat 130 with a movable contact. The closure of the current occurs by the hook 134 on the shaft 2 (Fig. 9). At that moment, when the shaft 2 with the line written becomes against the printing mechanism 3, the roller 55 is pressed against the shaft 2 and rolls the paper onto the written line. When the shaft 2 moves to the washer, it will, by hook 134, close the contact to the pawl 129 and allow the roll 38 to rotate for the required distance.

A moving contact on the rheostat 130 makes it possible to regulate the amperage, and hence the distance between the lines. If a thick layer of thin paper is wound on a roll 38, then as the paper is drawn, the distance between the lines may change. To prevent this, there is a fixture, namely: a row counter for a roll 38 (not shown in the drawing) after counting a certain number of lines, according to the paper thickness, introduces parallel 129 resistance and thereby automatically changes the resistance value and, therefore, the distance between the lines remains constant.

When proofreading, the reel 38 by depressing the pawl 129 by hand can move to the right place. In order to ensure against the possibility of reverse dragging onto the shaft with a small size of paper, while rolling the roller 39, the drum lettering is not against the center of the shaft, but closer to the front end. Under this condition, even if the roller 39 from the inside out passes over the line already dragged onto the paper, it will not cause this line to touch the shaft 2.

The inking unit (Fig. 4, b, 8) should ensure a uniform inking of paint only on the sign, which at the moment should receive an imprint, and in the quantity corresponding to the size of the font taken. To this end, the colorful roller 56 should only be suitable for the type of letter that is currently being printed. This is achieved by the following device. Due to the fact that the drums for all pins of the same diameter and letters are located around the circumference at the same distance from the center of one letter to the center of the other, the pin can not be taken into account in the process of rolling paint. Roller 56 approaches drum 7 and becomes at the moment when the next letter should be painted in the gap between two adjacent letters (Fig. 6). Upon further rotation of the drum 1, the letter presses against the spring-loaded colorful roller 56 and the paint rolls on it with a rolling motion. This will take place .dl all letters, regardless of the size.

only at small pins, the roller will wait longer for the letter to arrive, and at large pins, x-less. In order for the roller 56 to be opposite the bottommost letter around the circumference of the drum in a place opposite to shaft 2, there should be 2-3 free slots on the drum, i.e., not occupied by letters. Then even the very low letter itself, when turning the drum, will meet a colorful roller. In order for the roller 56 to approach the desired letter, the rod 120 of the key 102 closes the contact pads 121, 122 (FIG. 4) on the electromagnet 123. The contact pads are located for each key at a different height and, therefore, the short circuit also occurs at different times depending on how much time is required for the drum / letter to become the zone of action of the paint roller 56. Sites 121, 122 are of the same length and, therefore, the current is closed and the roller 56 is always moved to the same place equal to the distance between the middle of the two letters. When the pads 122-121 have been passed by key 702, the letter has been rolled and the ink roller 56 returns to its original position, as the current on the electromagnet 725 opens. During the reverse movement of the key 102, the platforms 722-121 are not connected, since the rod 120 does not give the contact when moving backward. The translational movement of the roller 56 is caused by an electromagnet 725, which pulls the rod 72 made of soft iron, attached by means of the handles 725 to the roller 56, rotating around its axis 726. When the spring returns to its original position, the roller 56 contacts the rubbing roller 55 in independent rotational motion. A change in the force of the knurling can be obtained by changing the current in the coil 725. Paint is supplied to rollers 55 from reservoir 64-66. The amount of paint supplied is adjusted according to the font size by the following mechanism: the paint is supplied from the tube 66 (Fig. 1, 5) with a working ink supply. The tube 66, laid within the site 75.5 in its wall by means of

tube 65 is connected to a rubber balloon 64 or a cylinder within which a piston runs. The cylinder is compressed by screw 63 as follows. A screw 63 (Fig. 8), fitted with a spring, is kept in the initial position by the pawl 757 entering the teeth of the screw 63. The pawl’s departure is associated with current closure during movement of the handles 725 associated with the return of the paint roller 56 to the initial position with the platform 755, closing current in only one direction. By setting the rheostat 727 to the desired point of resistance, adjust the time of departure of the dog through the electromagnet 752 and thus the degree of rotation of the screw 63, and hence the amount of paint squeezed onto the roller 55.

The inking unit is located on both sides of the drum 7 and the ink is applied only to the printing mark.

The work of the maschina is performed as follows. Through the slots of the plates 708 in the WO sinuses, the drum / font is fixed and the pin, then the screw 44 (Fig. 3) sets: the shaft 2 stroke on the pins and the font and by contact in the rheostat the amount of paint supplied according to the pitch, then the rheostat 730 sets the distance between the lines, and then, when pressing on the desired key 702, the following processes simultaneously and sequentially occur: a) the drum 7 becomes opposite shaft 2 with a series of characters, b) the shaft 2 moves a distance equal to the width of the printed mark, ) drum The en 7 is turned by the required letter to the shaft 2, d) the paint roller 56 comes up at the appropriate moment and rolls paint onto the letter, e) the shaft 2 rises and presses against the rolled letter. At the end of the word, the corresponding gap is made by the action of a special key giving only the movement of the shaft 2, and when the line comes to an end, a signal is given (ringing, light), then the screw 24 turns off the line and the shaft 2 is turned by pressing the button. The roller 39 presses the paper (or material) to the shaft 2 and rolls it, and the roll 38 moves the imprinted line for the set interline distance, after which the line with text traces on the shaft enters the washing machine, is cleaned and dried.
