Description

Patent No. 9530 describes a writing machine device in which a string-stripe ruler is hinged to a plate connected to the top with a spring and a board located on the back side of the same plate, and from the bottom connected with a ratchet cord and moves along the rails pressing the keyboard lever connected by a flexible shaft with the lever carrying the dog. The present invention relates to a modified device of a desk for typewriters, in which the display line is guided by a rod and connected at the top by a spring, and at the bottom by a cable connected to a ratchet, rotated by the action of a button dog.

In the schematic drawing of FIG. 1 is a front view of a proposed writing stand for a typewriter; FIG. 2- side view; FIG. 3-arrangement of the mechanism for moving a string of indicative ruler.

A support 2 is mounted on the stand 1, carrying a support board 3 which is rotatably fixed, provided with its side 4 located on its side, to which a fixed ruler 8 is attached, which serves to secure a rewritable sheet of paper on the board 3 under the action of a spring 5 on a half ring 6 located at the bottom of the board music stand. The row indicator line 7, which moves along the side rod 4, is suspended on a spring 9 connected to the side rod 4 and connected by a cable 10 passed through a flexible pipe 11 attached to the uprights 12 to a grooved ratchet 13, closed from the bottom by a plate 14 preventing the cable from jumping off and having a longitudinal cut in the middle of the ratchet groove; on the axis of the ratchet 13 there is also a shaking plug 15, which is under the action of the spring 16 and enclosing the pawl 17 on the button 18, behind which there is a pawl 19 that serves to prevent the ratchet 13 from rotating arbitrarily.

A rewriting sheet of paper, pressed by the action of the spring 5, is laid on the easel board 3 under the fixed ruler 8. Next, the display line 7 is installed under the first rewritable line and is sequentially moved during operation by pressing, previously raised by the action of the spring 16, together with the fork 15, buttons 18, with the pressure of the pawl 17 of which the rotatable ratchet 13 winds a cable 10 connected to ruler 7 to its chute. To move the string of the indicator line 7 to its original position, PC 18 and dog 19 at the same time tap ts back

and the ratchet 13, under the action of the spring 9, unwinds the cable 10, and allows the ruler V to go up.

Subject patent a,

A variation of the writing stand for the typewriter described in the patent, characterized in that the movable ruler 7 is connected at the top with the spring 9, and at the bottom with the cable 10, passed through the tube 11 and connected with the ratchet 13, for rotation of which serves the pawl 17 on the button, 18 , for the direction of movement of which ruler 7 serves the side bar 4.
