Description

The proposed typewriter is designed to print Tjino text in a graph font; for which it is equipped with a replaceable drum to reinforce on its surface a letter of a corresponding size, and below this drum there is a shaft composed of iodine spring segments, width B4) din printing point, serving for printing a drum on them, and for dragging typed garbage In the image of the stitched and printed on the segmental shaft stitch on paper - to the line of the 5th page. The paper tape is specially designed for special rollers. For washing off the paint after imprinting the stitching from the segments, the axial sponge rollers, which are lowered by half, are used.

In FIG. 1 shows a schematic cross section of a machine; FIG. 2 g-longitudinal section of the shaft with ogmentami; FIG. 3 — device for carriage advancement; FIG. 4-pshemu; FIG. 5-Band colorful playground; fngpb - view of the washing table; FIG. 7 and 8 is an insertion circuit for the use of a drum with letters. -

As can be seen from the diagrams depicted on the front panel, the machine consists of the following basic parts: from 1 to the font of a certain point; shaft 2, perceiving the impression, with a mechanism that turns off the line; a printing mechanism 3 transferring a line to a paper or other material written on a shaft; Nekhanizma 4 - an employee for moving the shaft across the width of the cast,) s, n paint apparatus. Drum 1 is mounted on barbell 6 and can be quickly removed from it. A beech and signs5 are on the drum in three rows. The letters in the drum can:; leave with him one single, or be fixed in special cells. The bar-6 at the other end has a counterweight of 7 soft iron, allowing rotation of the bar, and dial 9, through which the handle 8 directly connected to the shaft 8 walks. The bar of the 3 soft iron, which is included in the electromagnet 12, is attached to the bar 6. The heel of the rift is given to the drum by the support 10, around which the rod 6 can move up and down.

The dial (Figs. 1, 4 and 7) consists of a series of 14 cells with raised tailpieces 15, giving a strictly center pp; the position of the handle 8. In the cell, the decimal places correspond to their location on the drum 1. At the bottom of the cell there are two spring-loaded brad 16- (above) and 17 (below). Moving the knob 8 to the appropriate cell 14, simultaneously turn the drum 1, let it accurately set against shaft 2. When the knob 8 is lowered into cell 14, MjuKiieTCsi through it and pin 17 current on the electromagnet 12, which pulls

the rod 11 at a certain depth and causes the drum 1 in contact with the shaft 2 and transmits to it the imprint of the letters from the drum.

When the rod 6 is raised, then the rod 11 by the plate 18 closes the current of the electromagnet 13 (Fig. 8). With the start of movement of the rod 11, the current is disconnected, and the counterweight 7 departs, and with the transition of the knob 8 to another cell, the current to the electromagnet 12 opens, and the rod 6 by the electromagnet 13 and the counterweight 7 is fixed in the initial position. The rotation of the drum can also be performed by the keyboard (by pressing the button, by a rotating mechanism. The bar is turned and all other mechanisms are turned on); If a drum is required during a change

The big size, the drum and the mechanism connected with it can be lifted by the SCREW 71. The working part of the shaft 2 is made up of metal segments, each widening in one tiaographic point. The length of the usable area Vlla7-Zkvadra. Comrade Shaft 2 in the longitudinal direction forms four sections consisting of segments 25, and interposed solid sections 20 between them, mounted on ridges 70 of axis 22 of shaft 2 (Fig. 2).

All segments are connected to the bottom of the axis, and at the top of the rod 23, ending screw thread and screw 24. The axis, the rod 23 and section 20 provide a stable position segments 21 for aligning the line. Each segment has

spring 26. Being screwed by screw 24, all segments form a continuous groove (Hyk) surface. Screw release,

due to the presence of springs 26, segments

the section is wiped out by a tiny amount,

and so the string is brought to

the length of the desired size.

: This device allows you to turn off the line independently of / font and size with the maximum point and, when proofreading, compress the line) The segment above represents the area, the size and size of which corresponds to the largest size the machine is designed for. The number of seitions is due to the following processes. The printed line, by the movement of the axis 22 (by a conventional electromagnetic device), is always turned to ONE and: The same value is set against the printing mechanism 3 and gives an imprint of a ribbon on the boom. At the next turn of the a-lane, the line advances to the mountaineer 27 and the wiper 34, after which the surface of the shaft 2 returns to its original position. The axis 22 is fixed motionless on the support 69. Each movement of the axis 22 of the shaft 2 through an eccentric gear ly 35 drives the paper reel 38. The coil's jaw (interline g) is adjusted by a screw 36, and the device 37 rotates the transmission and allows the shaft 2 to rotate independently or coils, 1g 38; From the axis 22, a rubber roller 39 is set in motion, pressing the paper against the shaft 2 with a rolling motion.

Shaft 2 is adjoined to shaft 2 (Figs. 1 and 6), which consists of two three toothed rollers 28, 29, 30 rotating in troughs with a paint-dissolving liquid. This fluid is gradually updated by the base vessel 33 by the mechanism described in the inking apparatus. Roller 54 rubs shaft. A narrow mirror 40 is fixed above shaft 2, which is pressed downwards by pressing down the lowering drum 1, and when the letter oinenaTaHa.i then its reflection is visible in the mirror. On the shaft 2 of the Ogtl, the letters reach the base up and from left to right. The line printed and turned off on the shaft 2 is transferred onto the paper with the help of mechanism 3, consisting of a roller 38 with a ton of b-magic, a rubber roller 39, pressing the paper against the shaft and rolling it, and a spring roller 41 on which is wound typed text. To the coil attached paper consumption counter. ,

The whole mechanism after installation acts automatically, i.e. while one line is imprinted, the next one starts to be dialed. The movement of the shaft to a distance corresponding to the width of the letter is provided by the mechanism 4, and the carriage with the shaft is moved in the usual way. The pitch of the grid provides a cone 42 (figure 3, -Ch). According to the calculations, deep cuts 43 were made on it. Having set the cone with the screw 44 according to the pointer 45 to the corresponding position to the delaying dog 47, the carriage step is determined in relation to the size of the selected font, t, e. the distance is determined on which the cone of the retractable-tip carriage will turn. Within a single point, movement to different widths of the letter is governed by the time it takes for the dog 47 to move away from the cone.

The design of this mechanism is based on the following considerations. If one and the same letter is of the same size, different fonts, then the thickness of the letter (it is the letter, not the width of the point) can be made up of a number (almost the ratio remains constant for different letters). This, that, taking into the installation on some middle letter Hdpustim, N), we can give a step to the carriage by the movement of the cone, which will correspond (in width) to the place of the desired font in the general scale of the fonts .-.

In the limits of each font, the thickness can be limited to eight groups, i.e. the time for the dog to move away from the cone should be varied so that, while maintaining the average pitch taken for the font, the individual shaft steps can be varied.

Since practically the letters of one size (in thickness) also form a series of repeating coefficientsI, then, taking into some basic type (common divider) for eight groups and drawing from this calculation in-depth cuts along the cone, can be obtained from the cone vertex to the base, the correct increment of the carriage step for each of the eight groups; This step corresponds to the given letter given within the bounds of the font. The point will always be in the center of the place allotted to him and, therefore, the correct distance between a number of STANDING letters will be ensured. .

The time of departure of the 47 from the cone, 42 is regulated by the following meldism: in the cell 14 of the dial 9 (..4 - in. 7)

or in the button cell with a keyboard, there is a prominent spring-loaded piece of ftik 16 located above the shaft 17. The bolt 16 moves in the cylinder 52, and on the wall of the cylinder 52 there is a movable contact 53 held by the spring in a horizontal position; its bottom surface is covered with insulating material. There is a contact pad 51 on the pin 16. The handle 8 presses the pin 16 with a pin 51-53 and closes the current to the rheostat and electromagnet 50. When the pin 16 moves in reverse, there is no current closure. E.1, the electromagnet 50 draws in the rod 49 of the pawl 47 to a depth proportional to the strength of the passing current, which is regulated respectively by eight rheostats connected to the corresponding cells. Because of this, the time of the 47-h48 dog's distance from the teeth 43 of the cone 42, and, consequently, the step size within the limits of the pin, changes. The whitespace cells have contact 16 only on the dog, i.e., the shaft movement without impression. The shaft is reset to its original position by the usual mechanism, but not by hand, but by foot.

The inking unit (Fig. 1 and 5) consists of a roller 56, movably mounted on a stand 58-60; The drum 1, lowering, hits the roller 56 with a letter, rolls paint onto the letter and pushes the roller onto pad 54, reinforced at the part-time 60. There are several rubbing rollers 55 on the pad and a series of versions 67 through which paint is applied to the pad. The movement of the rollers is guided transversely by a plate attached to them. Spring 68 returns the rollers to their original position. The inking roller 56, colliding with the rollers 55, runs down some distance and resumes on a layer of paint. The paint is applied to the pad from the tube 66 with a working ink supply. The tube 66 via the coefficie tube 65 with a rubber balloon 64. The cylinder is compressed with the screw 63 through the transmission bar 61. and the gear 62 each time the roller 56 pushes towards the platform: 54, the transmitter, 59, is set in motion.

First, a drum with the required font and the desired size is mounted on the bar 6, and the screw 44 g. 3) install the shaft stroke on the Font and the font, while screw 36 (Fig. 2) installs Fasto nyyo between the line, put the hand into the desired cell; 14 on the dial9; at the same time, the shaft 2 is moved to an area equal in width to the printed sign, and the drum 1 is lowered onto the shaft 2, rolling along the road. According to the pKOHMiaHHT-word, line alignment is done, and when the line comes to an end, an 11/2-G square is given a sound or light signal. The screw 24 turns off the line, after which the shaft 2 is turned by pressing the button. The roller 39 presses the paper to the shaft 2 and presses it, and the reel 38 moves the printed line upwards by the set line spacing 10. At the next turn, the line with the text on the shaft goes into the washing the apparatus is cleaned and dried. Proofreading can be made on the shaft in the process of writing, namely: individual

letters can be corrected by looking at the wrong letters and putting new ones in their place; if the new letter is wider than the old one, then the screw 24 expands the gap, and if it does, it narrows. Replacing whole lines occurs by moving to a new line. On paper, proofreading is carried out on a special proofreading table, with either an erroneous letter cut out and pre-laid (stencil) enclosed, or an erroneous line is cut out and a newly-written one is enclosed.

The layout, depending on the nature of the text, can occur either in the process of the letter itself, using instructions from the ShE counter to the shaft and the bar, or from the edges prepared on the machine. For illustrative purposes, either the space is left in advance, or the next assembly is carried out.
