Description

Apart from the reverse direction, the difference between the Tatar letter and the European one is that the letters in the words are not only written but also printed, and this is necessary ((The length of different widths for letters of fonts is one size in a certain proportional dependency) .IOSTI.

The present invention aims at adapting a typewriter for Aatar writing. In addition, there are devices for use, in parallel with the main one, of a different type, which differs in size from both the Tatar and European ones. The introduction of an additional, larger font is necessary, in the absence of capital letters in the Arabic-Tatar alphabet, replacing the second font in the European typing machines for selecting text.

FIG. 1 shows a section along AB of FIG. 4, in FIG. 2 - spring dogs; in FIG. 3 shows a section along the CD of FIG. 4, in FIG. 4 is a top view of the device for moving the carriage by any value; FIG. 5 is a diagram of the keyboard device and in FIG. 6 - movable plate with notches.

Common in all writing machines. Ratchet 7 (Fig. 1. 3 and 4), compelled to intermittent rotation of the main spring machine, interacts with several dogs 2, 3. 4, 5 ((-lt. 1, 2, 3, 4) located in a row on the bridge, rocking in a plane, almost perpendicular to the rotation xpanoBiMKa 7. Clinging to these dogs, the ratchet tooth 1 moves them away And, when the bridge moves, it moves from one dog to another, due to which the wheel turns on the angle required to move the carriage by a certain amount. Dogs that serve as an upset for snoring 7, 8, 9 (Fig. 1 and 2) in the direction opposite to the pressure of the toothed wheel 6. Ratchet 7, on the press on the dog underneath and pulling the eei to the fullest, is placed its closest teeth between the end of the neighboring not yet pressed dog, and upon further movement of the bridge

allows it to advance to the indicated, interlocking, for delaying the next following the tooth that has descended from the dog. ; The marked dogs 2, 3, 4, and 5 have a form of plates (Fig. 1, 2. 3, 4) (each with a tooth-like tip at the upper end) moving with their two longitudinal notches along its length along the axis m / O. , 77, 72 (Fig. 2) and separated from each other by spacers 73, 74, 75 (Fig. 2). Axles for dogs and adjacent gaskets between; dogs turned from one piece | in the for.ch there are washers and are mounted on axial screws 76, 77 (fig. 1, 2), with which: the axes of the dogs are fastened with the plates of the bridge 78 and 79 (fig. 1. 2, 3). |

The movable bridge 18, 79 consists of two plates (Figs. 1, 3 and 2), fastened on the upper edge with the indicated: above axial screws, and on the lower edge - screwed to the bar 20 (Fig. 1 and 3) of the axis of the bridge; the axis is clamped in the centers 27: and 22 (Fig. 1), placed on the crowns, mattes 23 and 24 (Fig. 1) of the machine frame. The lever 25 is screwed to the same axis from one side (Fig. 1 and 3). i by means of which tga 26 (fig. 1: and 3) priv: the whole bridge is swinging into motion. j

The crawl} 27 (Fig. 3) is mounted on i of the bridge described above and is forced by the spring 28 (Fig. 1 and 3) to move along the row; dogs 3, 4, 5, and the slider, when the latter are not pushed back by the ratchet 7, rests on the front edge of the nearest dog. When moving the same | As the 7 ratchet moves the ratchet away, the GEOStepvno slider moves forward to each doggie opening space and, keeping all the time directly, but following the ratchet 7, is positioned in front of the dogs it covers, up to dog stop 29 (Fig. 3) and holds, thus, the tips of the dogs in the distanced position. B. Instead, pushing its upper edge 30 (figs. 3 and 1) on the nose, is level with the tips of dogs, the slider serves as a stop for the teeth of the ratchet 7, instead of dogs covered with them,

1solso. the slippage along the edge 30 of its m. tooth, remains unchanged in the continuation of the entire bridge displacement time. On the reverse side of the slider 27 is provided with a protrusion 37 (Fig. 1). abutting against one of the delays 32, 33, 34 (Figs. 1 and 4). Having met with a delay put forward from their number on their way, the slider ceases to follow the bridge and stops, revealing the corresponding number of the dogs that have successively protruded from the slider with further movement of the bridge. The movement of the slider in this case is carried out by strengthening it on the rod 35 (Fig. 1 and 3), the lower end of which, in the form of a hole 36 (Fig. 1 and 3), is put on the axis of the bridge 37 (Fig. 1 and 3). in order to avoid warping when moving the entire system. The thickness of the upper edge of the slider and the tips of the dogs should be proportioned so that they fit together freely between the teeth of the ratchet 7 and, moreover, the dog 2 must be different in order from the other dogs 3. 4 and 5 with longitudinal cutouts for so that the ratchet tooth 7, resting on its tip, would be positioned in front of the edge of the po-chzuna. B initial.m to the south of the bridge, the slider 27 is in front of the pawns 3, 4 and 5 put aside and rests with its front edge on the pawl 29 (Fig. 3), which is located in front of the inner side of the pawl 2; the same bridge is pulled away by a spring 38 (fig. 2 and 3) until the rear edge of the pozun meets the adjusting bolt 39 (fig. 3) fixed on the machine frame at such a height, at which the first dog is mounted on the bridge exactly under the snoring tooth / ka 7.

In the first stage of the machine’s operation, when parts of the mechanism begin to move forward, the UUSTIK also begins, in front of V Igats, in the direction opposite to the initial position, with the first doggie supported by the ratchet 7 in its original position, and in place of the dog there is a slider 27; ratchet 7, remaining

in its unchanged position, it passes with its tooth “and the slider, slips along its“ upper edge 30 during the whole displacement of the bridge, up to the imprint of a letter, i.e. hitting the letter sign on the paper. At the same time, the slider, after moving the ratchet tooth 7 to its edge, touches with its lugs 31 for one of the delays 32, 33, 34, which protruded from the row, and stopped; upon further movement, the bridge releases a certain number of dogs moving out from under its transmission.

In the second stage of the work, the mashes, by imprinting a letter, when parts of the mechanism return to their original position, the bridge, under the action of the spring 38, moves in the opposite direction, with the tooth, than the ratchet 7, resting its tooth on the edge of the slider 30, slides along him, up to its front edge, abutting against the last of the dogs that had previously emerged (in forward motion). At the same time, the tip of the dog is positioned before the subsequent tooth of the ratchet 7, with further movement of the bridge, the ratchet 7, leaving the edge of the ram, passes to the indicated tip of the dog with its emitting tooth and moves it away. Further, in the same way, the transition to the next dog, the ratchet 7, turning at a certain angle, returns to its initial position - the first dog. At the same time, the slider 27, from the moment of the ratchet 7 moving from the edge 30 to the dog, was always moving with its front edge directly behind the ratchet 7, to the street on the next co6ai4ku, and simultaneously resting its rear edge against the rear edge Uyushy bolt 39, is moving along a row of 7 dogs pushed back by a ratchet and reaching from the top to a protrusion in front of the first dog 29. At the same time, the possibility of one Time to pick up more than one dog is eliminated by the fact that the slider touches its front edge of the advanced part closest to the n When the dog is under the ratchet 7, P1 goes with its opposite end into the head of the adjusting bolt 39, as a result of which the bridge stops, "the ratchet tooth 7 cannot touch the adjacent dog while it is pressed on the dog. When the ratchet 7 has removed the proper dog, the slider 27. all the time left directly behind the NSh1, is no longer holding anything. under the action of the springs 28 and 38. advances along the row of dogs, and the bridge gets the opportunity to continue its movement until it touches the crawler with its front edge of the cedar} just 1 dog; At this point, the next dog is located exactly under the next tooth of the ratchet 7.

Delays 32. 33, 34 (Fig. 1 and 4) hold & slider 27 when moving the bridge, in order to release the required number of dogs protruding from under it. They are mounted on the frame of the machine and represent a series of springs 40, 41 under the action of the m. 42 (Fig. 1) cranked rocker arms, swinging in the special grooves of the box 43 (Fig. 1 and 4) on the common axis 44 (Fig. . one). The delays, in the number equal to the number of dogs without one, are placed parallel to each other at a distance corresponding to the distance between the dogs, and are connected to the keyboard by means of keys 45. 46. 47 (Figs. 1, 4 and 5). When lowering the end of one of the delays 32, 33. 34, the first one (connected to the tractor), moving in its groove, takes a certain position, jutting forward with its other end on the path of the follower 37 of the ram 27. When turning the ratchet 7 only 1 prong, that does not occur from the first pawl 2 to the edge 30 of the ram and returns to the same pawl, when it is retracted, which has already stood out and located under the next ratchet tooth 7 (in the STO..I case, delays do not work). When pivoting the ratchet 7 into two or more teeth, simultaneously with the beginning of the bridge movement, it protrudes from the CBOHIX niasoB first or one of: following the order of the delays 32, 33, 34. due to which the slider is retracted by a certain amount, when which the second or subsequent dogs get the opportunity to come out from under, him, and ratchet /, | when returning to the initial position of the bridge, stepping successively along them. Returns to the first dog: takgm izvolt. the ratchet 7 is rotated by two or more teeth, depending on the number of loosening dogs. One or another number of dogs acting in this case (the first, denoted digits 2) depends on the one that is set in motion from the delays and left the progress of the slide, i, as a result of which the intervals between delays 32, 33. 34 exactly the same with the same between; dogs 2. 3. 4, 5.

To bring the running gear; In interaction with the rest of the machine, In addition to the usual ms. in typewriters, additional devices are introduced; the names / names are op-nick and: above changes in the design of the walking mechanism. ; namely;

So that when printing any; letters could be drawn from the carriage: by an appropriate amount, each key must be associated with one of the other delays that regulate the movement, retk11. For this purpose, under the keyboard, along the entire keyboard there is a series of moving ones. slats 4S, 49, 50 (Fig. 5), lowering when the lever is pressed on them: key: machine heads, and each heat serves only one corresponding IB from delays and therefore is pressed only by certain keys, which I read letters of equal size, which have the same space in the line, the poet (Mu 48, 49, 50 if-hme against the letters of other groups from above cutouts 52 (Fig. 6), so that the lever of the keyboard: ISH1I with a letter of other sizes did not reach before it when pressing. At both ends of the slats there are holes 53 (Fig. 6), es which extend rods 5 / (FIGS. 5 and 6), the retaining straps in parallel

initially 1m position when lowering and raising. In addition, each strip 48. 49. 50 has, at the ends, a bracket 54 (Fig. 5 | I 6) with which it is connected a lever; azh 55 (Fig, 5) attached to rods swung at its centers. 56, 57, 55 (figs. 5 and 6), the purpose of which is to eliminate the possibility of skewing the slats 48, 49, 50 under the action of the side 1 key machine. The rods 56, 57, 58. located another | under the other and. Swinging on the centers fixed in the sideframes of the typewriter serve as a transfer of the movement to the crank levers 59, 60. 67 (Fig. 5), the other end attached to the t 45, 46, 47, coming from delays 32, 33, 34. All levers for letters and. characters equivalent in width to the place occupied during printing and the carriage movement required for this, are connected by a transmission mechanism, with a corresponding one or another delay, through joint action ia one common bar 48, 49, 50. As a result, / 1I of all the described parts of the mechanism, each click on the key will correspond to turning the ratchet 7 by one or another certain number of teeth.

In order to receive letters of any exact dimension on the machine, an additional gear 64, 65 (Fig. 1 and 4) of double width is inserted between gear 62 (fig. 3, 4) ratchet 7 and gear rack 63 (fig. 1 and 3) of the carriage. , with such a ratio of teeth, which the lava would be able to move the carriage to any value necessary for the letter mark, not determined by the smallest carriage head. It was also necessary to introduce this in order that, depending on the font, it would be possible to freely change the gear itself, keeping the remaining parts of the mechanism unchanged.

In the proposed machine, a second font is introduced which differs from the main one only by the height of letters (as the capital letters of European letters differ from upper-case letters, but also by the length of the line. The changes necessary for this purpose in the carriage transfer are achieved as follows: 64 and 65, of different diameters (Figs. 1 and 4), by which the electronic movement of the machine mechanism is adjusted to the desired value, along with it (Fig. 1 and 5), connects to the same gear 62 of the ratchet 7 (from the opposite side) at a pair of torus similar to the sameStepHOK 66, 67 (Fig. 1 and 4) with the same relative sizes AKajvieTrov. so that, when turning the ratchet 7 at the same angular values, the carriage would move accordingly to the second font spacing. the other pair is designed to engage the carriage rack and are flush with the rail, but in different parallel planes, p to 1M, one next to the other, as shown in FIG. 4 and 1.

Moving the toothed rack 63 of the carriage when changing the register is achieved by hanging it on two brackets 68 (Fig. 3 and 1) attached to the centers on the centers of the rod 69 (Fig. 3), which serves to eliminate warping (and roller when changing In the event of a register change, the rod 69 rotates on its axis at an angle, with m. The arms 65 with the toothed rack 63 move somewhat, due to the fact that the grip of the lath with one of the leading gears 65 or 67 is achieved (Fig. 4) , depending on the font. So They press the register-changing key simultaneously with the carriage underneath it, it clings to the drive gear, which sets the stroke of the upper-register carriage.When the key is released from the press, the roller goes to lower case and Simultaneously Ho with this rack engages with the lower gear drive gear 65.

For use on a typewriter in parallel with the Tatar font a lot of font that you need to write in

the reverse (than in Tagar) type, the described adaptations for the second Tatar font are somewhat modified, namely: the double gearbox 66, 67 connected to gear 62 is removed, and (removed) with the same gear wheel through The above-mentioned gear 64 (which is intermediate) interlocks the new double gear 70, 71, depicted in the figure in FIG. 4, in compliance with all the above conditions for moving the toothed rack of the carriage from gear 65 to the gear of the new pair 77 when the register is changed. Thus, the double gear 70 and 77 will rotate in the opposite direction to the gear 64 and 65, as a result of which, when the carriage rail engages with the gear 77, the carriage can move in the opposite direction. In addition, to move the carriage, optionally in the forward and in the opposite direction, all the way around, move the point of attachment of the main machine spring from the carriage to one of the parts of the chassis. In this case, this is done in a farm located on a spring drum 72 (depicted by the dotted line in Fig. 4) of the gear 73 (Fig. 4) of a slightly larger diameter than the drum. The drum 72 is mounted on the frame of the machine in such a way that its gear 73 would engage with gear 77, on the other side of gear 70, and the machine spring, driven by a running gear, would also move the carriage. With such a clutch, the possibility of excessive load is removed when moving the drawer of the arm by hand to plant the spring and drive the carriage in the process of writing to the beginning of a new line.
