Description

Patent No. 6806, issued to the author, describes a row indicator for writing and the like machines, in which a rack and a gear wheel are used to move the index line of the music rest. In the proposed modified line indicator, instead of a toothed rack connected to the index ruler and hooking it to the toothed wheel, a roller is used, equipped with a gear and connected by a cord with a ruler moving along the rack; In addition, a plate attached to the shoulder is used for hanging the originals in a modified line of the pointer, and a tube with clips is used for copying from the book. To move the pointer, in a modified form of the proposed line, the key with a pawl is used and there is an additional tube with a spring, and to adjust the amount of movement a screw is installed on the bracket with a counter-knob.

In FIG. 1 shows a front view of a modified row of the indicator; FIG. 2 is a rear view of the top of a tubular rod with a roller; FIG. 3, 3 and front, top and side attachments for hanging originals; FIG. 4, 4 and in front, top and side of the device for rewriting from the book; FIG. 5 - front view of the modified lines of the display in a different form of implementation; FIG. 6 is a rear view of the parts of the string located on the top of the tubular rod.

The proposed modified string indicator consists of a rod 1, on which the tube 4 of the ruler 2 can move, having notches 3; the rod 1 is fixedly connected to the tube PS; the tube 4 is connected to the cord 5 wound on the roller b (Fig. 1) and attached to it. The roller 6 rotates in the supports 10 and is provided with a gear (Fig. 2), the teeth of which abut the dog 8c with the handle 9. The dog rotates on the fork 7, which in turn rotates on the axis 26 and has a spring 15. A cable 16 is attached to the fork 7, passing through the flexible sleeve 14, which is attached to the tube 11 by a string 13 (Fig. 2). The lower end of the sleeve 14 is connected to the stand 17, and the cable 16 coming out of the tube is attached to the push lever 18. The latter can rotate around an axis fixed on the base 20. The turn of the lever is limited by a screw 19, screwed on or unscrewed on the base 20. To strengthen the row indicator in a vertical position, it is sufficient to screw the tube 21 into the IT tube, which is fixed in the tube 22 of the bracket by means of a stop screw 23; the bracket is screwed to the table with a screw 25 (Fig. 1).

Suspension of originals is carried out by means of a device consisting of a plate 27 (Figs. 3, 3 and 3), having an opening 30 for insertion of the rod 1 into the folded end and a bracket 28 for fastening with the latter. If it is required to rewrite from a book, then a device is used having a tube 31 with ribs 33 and brackets 32 (Fig. 4, 4 and 4).

When copying from a horizontal sheet, rod 1 without tube 21 is placed on paper that is attached with tweezers to the folded end of rod 1. Then the handle 9 of the dog 8 is pressed and, setting the ruler 2 to the required line, release the handle 9, and then rewrite the line. After rewriting the line, press the lever 18, which causes the cable 16 to swell, and with it the fork 7 with the dog 8, which, in reverse, moves the wheel b to the corresponding angle. The amount of movement of the ruler depends on the angle of rotation of the ratchet 6, which, in turn, depends on the depth of pressing the lever 18, adjusted by the screw 19 (Fig. 1 and 2). If rewriting is done from a book, a tube 31 is put on the end of the rod (Fig.

4, 4, and 4), which, with its edge 33, engages over the edge of the book, and with the clip, 32 onto the edge 1.

The ruler 2 described above does not fall down when the rod 1 is in a vertical position due to the fact that its end is on the weight and is connected with the spring 70 (Fig. 1) abutting the rod 1.

In the modified form, the% fulfillment of the line shown in FIG. 5, there is a key 41 with a spring 47, pivotally connected to the pawl 8 abutting the pinion 6. When the button is pressed, the ruler 2 moves along the rod 1, and the amount of its movement is adjusted by screwing in the screw 43 in the bracket 42 having a counter-slide 44, abutting the drum rack b. The dog 44 is supported by the spring 45 and serves to prevent the roller 6 from rotating backwards. In addition, a tube 40 is additionally mounted on the rod 1, which is in contact with the ruler at one end and connected to it by the spring 70. The dog 8 (Fig. 6) is pressed against the spring 46 instead of spring 15

(Fig. 2).

The subject of the patent.

1. Variation of the string indicated in patent No. 6806, characterized by the use of a rod 1 supporting a ruler 2, which is moved by a roller 6 connected by a cord 5 with a ruler and fitted with a gear, to which the dog 8 is pressed, connected to a plug 7 connected by a cable 16 in the flexible sleeve 14 with the push lever 18, supported by the screw 19 adjusting the amount of movement of the ruler (Figs. 1 and 2).

2. When the line indicator, referred to in paragraph 1, is a device for suspending originals, consisting (Fig. 3, 3 and 3) of a plate 27 equipped with a tube 30, for hanging it on a folded shoulder 12

Bar 1, and staples 28, for scraping with rod.

3. When the indicator line, referred to in paragraph 1, is a device for rewriting from a book, consisting (Fig. 4, 4 and 4) of a tube 31 with edges 33 and brackets 32.

4. The form of execution of the row indicator specified in clause 1 is distinguished by; what to move

line 2 serves as a key 41, connected to the pawl 8, and to adjust the amount of movement on the bracket 42 supporting the counter-slide 44, is set to int 43 (Figures 5 and 6).

5. With the indicator line indicated in clause 4, the use of an additional tube 40 on the rod 1, connected to the ruler 2 by the spring 70 (Fig. 5).
