Description

In the proposed type of typewriter, a method of applying ink to the letters using a roller instead of a tape device of existing machines and the principle of removable carriages with a single-type skeleton of the machine are applied, so that the carriages of different sizes are easily replaced depending on the desired size of the printed sheets with the help of shtang, located at the carriage, and rollers mounted on the machine frame; at the same time tilting the carriage before removal provides access to the inside of the mechanism, facilitating cleaning and assembling it.

In the accompanying drawings of FIG. 1 - gives a general view in terms of the machine with the keyboard; FIG. 2 - cross section of the maschiny through the signal bell; FIG. 3 is a cross section through the paint roller along the plane of symmetry of the machine; FIG. 4 -15 give details of the device of the machine, and in all the drawings the dotted line shows the working position of the parts of the machine.

In general terms (Fig. 1), the location of the main parts and the methods of work, the proposed type of machine resembles accepted commonly used machines and consists of two parts: a skeleton with a keyboard and a font and a removable carriage with a roller for paper; in either part there are devices for controlling the operation of the machine.

The keyboard of the machine (Fig. 1) includes 45 keys with double characters on each block 20; In the block of the super-xy there are capital letters, numbers and i / i, / 2 and / 4 fractions in finished form, and capital letters and signs below.

When striking any key .I (Figs. 1, 2, and 4), the lever 2 with the letter block 20 is lifted with the help of wire grids 3, 3 (Fig. 2 and 3) and the square 4, rotating its notch 96 on the axis 95 in the slot of the segment 5. When passing the letter lever 2 to the shaft with paper 6 (Figs. 1-4), the letter block 20 encounters a paint roller 23 in its path, which rolls along the block, lubricates the small and large letter, passes the block to hitting the paper, the very same, slippery ends of the axis along the arcuate slits 26 of the frame 24, rises up and

stops above the letter block (Fig. 3, dotted line). During the lifting of the lever 2, its eccentrically rounded end 7 presses and retracts the frame 8 (Fig. 2 and 3), coupled with the swinging machine 9 (Fig. 1, 3 and 8), mounted on two stop bolts 94. In the machine 9 there is two teeth: one fixed 13, the other swinging 14; the teeth are located in planes displaced one relative to another by the thickness of the ratchet 15 located between them, with the tooth 13 located above the tooth 14 and the ratchet is in a quiescent state under the stop of the movable tooth 14. The gear 16 sits on the same axis with the ratchet wheel 15 interlocking with the toothed rack 17, hung in the earrings to the carriage. The carriage feed is performed by the action of the central spring enclosed in the drum 12 (Fig. 1 and 2) with the help of cables attached to the carriage frame. Being all the time under pressure from the spring, the carriage transmits this pressure to the ratchet wheel 15 with the assistance of the rail 17 and the gear 16, which sits on the ratchet shaft.

Lever 2, moving frame 8, down machine tool 9; wherein the ratchet 15, the exit from engaging with the tooth 14, is picked up by the stationary tooth 13 and remains stationary for the entire time the letter is printed. When the pressure on the keys is stopped, the lever 2 goes down, the frame 8 becomes in place, and the machine tool 9 rises up by the action of the spring 21 and the rod 3, and at the time the ratchet comes out of engagement with the tooth 13, the ratchet, under the action of the central spring 12, will rotate by one tooth, since this movement will be limited by the raised tooth 14. Rotation of the ratchet by one tooth will cause the carriage to move to the width of the gap between the centers of the letters. The adjustment of this gap is made by permutation of the screw 19 in the tooth slot. Springs 18 and 56 serve to restore the position of oscillating tooth 14 (Fig. 8, dashed line). When you stop pressing the key, the lever key, under the action of the spring 21 (Fig. 2, 3), comes to the horizontal position and with

t g 3, 3 folds the letter lever 2 on the stand; at the same time, the paint roller 23, by force of gravity, sliding down the slots 26 to its lower position, once again rolled over the letter block, lubricates the letters.

At the moment of impact of the letter pad on the shaft with paper, the beard 26 of the letter lever 2 (Fig. 3) passes through the guide of the letter-driver 25 (Fig. 3 and 4). The dye roller 23 (Fig. 1-4) consists of a main coil and a pack soaked in paint; in case of wear or replacement of the rollers {for working on wax paper, for a hectograph, or for lithography, the roller can be easily removed by unscrewing the side screws.

In the normal position, when striking any key (Fig. 3, 5), the letter block strikes the middle paper shaft for its paper with its lower part with uppercase letters or icons, to reproduce the same capital letters and numbers, the roller with the paper must be raised (Fig. 5, dashed line), for which the keyboard (Fig. 1) is on both sides of the register key 30, denoted by the letters BB. When pressing the keys 30, the end of its lever, coupled with the thrue 31 (FIG. 5), rotates the lever 32, which, by pressing, raises the bar 33 with the platform 34, on which the carriage with the roller 6 for paper lies. Lifting the platform 34 moves the center of the roller to the level of the upper marks of the boat. The accuracy of the lifting of the bar 33 I is regulated by a retained tooth 37 with a slit. When the key 30 is stopped, the platform 34 with the carriage i and the shaft 6, by the action of gravity, is lowered to the normal position.

For a permanent letter in capital letters on the left side of the keyboard: there is a locking device that consists of an additional lever 38 (Fig. 1 and 5) with a pin 39 and a spiral spring 40. When you press j the lever 38, the pin 39 drops into I corresponding the depression of the lever 30 holds it in an inclined position, as a result of which the average production shaft 6 will be raised for printing in capital letters. To disengage the i-pin with a notch, press keys 30; Spring 40 Ott. No lever 38, after which the lever key 30 and the carriage come to the writing position in small letters.

The carriage 11 (FIGS. 1 and 2) represents the metal frame, the carrier shaft for the paper and the printing control means. The carriage is inserted into the machine by pushing the rod 41 between two pairs of vertical rollers 42, 43, with two horizontal rollers 44 supporting the carriage in its extreme positions. The carriage is inserted, the axis of which is served by the rod 41, until the rod 36 is engaged with the four tapered rollers 35 (Figs. 1, 2 and 7), which are seated on the movable platform 34. The carriage is removed by pressing the button 45 (Fig. 2 and 7). ), located at the rear wall of the machine and coupled with the double-shouldered lever 46 and the bar 33, on which the platform 34 with rollers 35 lies; this pressure rejects the bar 33 and frees the bar 36 from being caught by the rollers, after which, by turning the carriage around the bar 41, the carriage can be tilted to the vertical position (dotted line, Fig. 7) and pushed in any direction; when turning the carriage, to pass the rod 36, the front wall of the machine frame deflects on the pins 47; the normal position of the wall is restored by the action of the spring 47.

When typing, the carriage moves progressively to the left; To reverse the carriage by one letter, use the lever 51 (FIGS. 2 and 8) on the right side of the machine frame; the lever axis ends with a shoulder 5G coupled to a pull 53, at the other end of which, on a hinge, a tooth 55 is slid, sliding along the plane of the platform 54. When pressing the lever 51, the sliding tooth advances, relieves from pressing the stop screw 57, abuts , under the action of the spring 58, into the tooth of the ratchet wheel 15 and rotates it by one tooth, as a result of which the carriage moves to the right by the width of the gap between the centers of the letters. With the cessation of pressure on the lever 51, the spring 59 ot no t gu gu 53 with a tooth 55,

which, due to the pressure of the screw 57, comes out of engagement with the ratchet 15.

To move the carriage to the left in the space between words, use a spacer device consisting of a key 90 (Fig. 1 and 3), which lies on two levers having a common axis of rotation with the levers of the letter key; the levers of the key 90 are connected to the rear with a rod mated to the machine 9. Each time you hit the key 90, the machine tool 9 tilts (Fig. 8), the ratchet wheel 15, under the action of the rail 17 and the central spring 12, rotates through one tooth, the carriage passes left by the width of the step between the centers of the letters, as when writing. Repeated blows move the carriage to the desired interval.

To freely move the carriage to the left, press the crank lever 27 (Figs. 1, 2 and 3), which is connected with a link supporting the rail 17; from pressure, the rail disengages from the pinion 16 and allows the carriage to move freely.

After the line has been printed, the carriage moves freely from left to right, the slide of barbell 41 in rollers 42 and 43, and barbell 36 in roller 35, with the oscillating tooth 14 (Fig. 8) deflecting as the teeth of the ratchet wheel 15 pass.

Along the length of the carriage is a shaft 6 (Fig. 1, 2, 3), supporting the paper during printing. The paper is loaded into the machine in the usual way and pressed against the shaft 6 by means of two pairs of rollers 89 (Figures 2 and 12) attached to the pads 86 by means of springs 87. The pads sit on the rods 88 and 88 running the full length of the carriage and mutually interlocked by adjacent teeth 86. Rod 88 is connected to lever 85; when pressed on this lever, both pads, due to the contacting teeth, are deflected in different directions, as a result of which the rollers 89 are pressed from the shaft 6, allowing to insert or remove the bumper or straighten it. With the cessation of pressure on the lever 85, the rollers 89 will press the paper against the shaft by the pressure of the springs 87.

To rotate the shaft 6, there are round knobs 66 on the ends of its axis (Fig. 1). The rotation of the shaft can be done either by sliding movement or at intervals corresponding to the distance between the lines; for this, a gear 62 is fitted on the shaft axis (Fig. 2 and 9), which is covered by two plate springs: with roller 69 and without roller 70; Both springs are attached to a four-sided block 68 with a handle 67 at the right side of the carriage. By turning the knob, the springs 69 and 70 are alternately pressed on the gear 62: in the first case, the spring roller 69, hitting between the teeth of the rack, gives the shaft a turn at intervals, and when the idle spring 70 is pressed, a sliding turn of the shaft is obtained. The flat spring 71, which presses on the edge of the pad, excludes the possibility of the middle position of the pad and the inactivity of the springs.

To rotate the shaft to a new line, there is a lever 60 on the right side of the carriage (figs 1, 10, and 11) with a swinging earring 61 at the end. With this earring, the lever hooks onto the gear 62, turning it by one or several teeth with each pressing down of the lever 60. The distance between the lines is set using a rotating column 63 having two studs 64 located on opposite sides and heights, and a side 65 ; the base of the column is fastened with a triangular nut, which is under pressure from a flat spring. The spikes and the side of the column serve to limit the swing of the lever 60 and, consequently, the rotation of the serrations 62; wherein the lower pinch makes it possible to rotate the gear by one tooth, the second pinch by two teeth, and the protruding rim 65 causes the shaft to be rotated by three teeth, according to which different gaps between the lines are obtained; A flat spring, which presses on the verge of the nut, eliminates the possibility of misplacing the plugs.

To set the stitch length, there is a rail with holes 82 in the back of the carriage (Figs. 1 and 14) and two installer 76 fields. The installers represent the levers 76 (Fig. 15),

one end of the fixed rod 83, which has a flat cut surface from the bottom, and the other end of the installer field ends with the handle 84. In the field of the installer, a screw with a head 77 and a pinch at the other end entering into the rail opening 82 are screwed in. A flat spring is pressed under the screw head, which presses against the cut surface of the rod 83. When pressing the knobs on the field of the 84 sets, pinch them out of the holes of the rail 82 and the box of the installers can be placed at any distance by shifting along the rod 83; when the pressure on the handle 84 stops, the flat spring holds the pinch of the installer in the hole of the rail 82.

To automatically stop the carriage at the ends of the stitch, in the middle of the back wall of the machine there is a swinging arm 71 (Fig. 6 and 14) having a hook-shaped protrusion at the upper end, and at the lower end the lever ends with a swiveling tooth 73 (Fig. 6) interlocking with the tooth 74 of the weights 75. When the carriage moves to the left, when, during printing, the screw head 77 of the right field, the installer will push the hook protrusion of the lever 71 and deflect it to the vertical position, the tooth 73 of the lever will hook onto the tooth 74 of the weights, will roll it when the carriage moves further and free t, when the teeth 73 and 74 are uncoupled, and the weight, by striking the bell chuck 78 (Fig. 2, 6), gives a signal about the end of the line. The movement of the carriage stops due to the stop of the lever 71 in the screw 72. In order to continue the same line a little after the signal, there is a device for pressing the hook protrusion of the lever 71 from the screw of the adjuster box (Fig. 1, 13, 14 and 15), consisting of a bar 81, pressing down the lever 71, when pressed on one of the levers 80 located at the ends of the carriage, the protrusion of the lever 71 coming out of engagement with the floormaster. When transferring the carriage to a new line, the spiral spring 79 deflects the lever 71 to the initial position.

When printing, the carriage moves under the pressure of the central spring.

enclosed in a drum 12 (Fig. 1, 2); adjusting the tension of the spring is performed by pulling it out to the full and turning to one side or the other of the bell cup 78; A bracket 97 with angular ends entering the holes of the center wall of the machine body serves to secure the tension of the spring. The tension force of the central spring is transmitted to the carriage by means of a flexible, non-expandable bond (for example, a cable, a string), reinforced to the frame of the carriage. Due to the use of a removable carriage and a method of connecting the working parts without the aid of screws, the maintenance of the machine is simplified: for example, cleaning and lubrication is done with the carriage folded down or extended; the letter levers are removed by simply removing them from the axle rod 95 and pulling it upwards; the keyboard levers, after uncoupling the coil springs 21, are easily removed from the prisms 91.,
