Description

The main patent No. 8014 describes a string indicator for typewriters in which folding screw pins and rollers covered with rubber are used to grip the rewritable original; a ratchet connected to a drummer is used to pull the original for a row distance; A wire arc is used to pull back the bottom of the original, and the paper feed is adjusted by means of the sliders and the key mechanism.

In the proposed indicator row, using a spring-loaded foldable ruler and an axis with rollers fixed on the bracket, it is intended to clamp the rewritable original, move the latter by means of a ratchet mechanism with cables, levers and a key and keep it from falling attached to the same bracket by an arc.

In FIG. 1 depicts the front row view; FIG. 2 is a side view of it.

Along rack 1 (Figs. 1 and 2), bolt 2 moves bracket 3 with shield 4 fixed on it with slots 5, 6, through which rollers 7, 8 pass on axis 9, rotating in bent bearings 10, 11, 12, 13. Equipped with forward bent bearings 14, 15 on axles 16, 17 and a ruler 18 deviating from this bracket, the ruler 18 carries an axis 22 swinging on a stud 21 or rotating in bearings and attached to it. the stem 48, which abuts against the spring 49. The axis 9 ends with the gear 23 and the pawl 24, to A cable 25 is attached, passing through a flexible tube 47, ending with two washers 26, 27 on a common axis, moving along a cutout 28, and connected to a two-arm swinging axle 29, which is in contact with another lever 30, also swinging on axis 31 and having a key 32 at the end. The levers 29 and 30 are fixed on the plate 33 with two ears 34 and 35, serving to rest it in the upper and lower part of the side cheek of the typewriter frame 36. On the plate 33 there is a bent shelf 39 with a thread, into which a screw 38 is inserted, abutting the same shelf 37 on the lever 30. On the crozstein 3, the ends of a curved wire 41 in the form of an arc 41 are inserted into the hole 40, which prevents the original 42 to be corresponded, missed between the rollers 7, 8, 19 and 20. The arc 50, draped hooked end on the axis 9, with its other end holds the arc 41 in the indicated in FIG. 2 position. The handwheel 51. On the axis 9 moves the paper manually, and the arc 43 with the screw 44 ending with the washer 45 serves to attach the keypad A to the cheek B of the typewriter frame.

A string indicator is placed behind the typewriter, while the keyboard mechanism A is applied to the cheek of the machine, fastened at the bottom with an arc 43 and screwed to it with a screw 44. Between the ruler 18 folded forward (see dashed line in Fig. 2) and the shield 4, the original 42 to be reprinted is entered, then under the action of the spring 49, the ruler 18 presses against the appendix 48 on the shield 4, as a result of which the original will be clamped by the rollers 12 and 13 of the ruler 16 and the rollers 7, 8 projecting into slots 5, 6 of the shield 4, and the device is ready for action. If necessary, submit the original 42 up, the typist presses

the key 32, while the lever 30, swinging on the axis 31, will lift with its short shoulder a swinging lever 29, which, having a reinforced cable 25 on its free shoulder, doesn’t have it; The last sweat is not behind the dog 24, which, having sunk into the teeth of the teeth 23, will turn the axis 9, and with it the rollers 7 and 8; with this movement of the rollers the original rises. The lift of the original is adjusted by a screw 38 on the keyboard device A, by reducing or increasing the distance between the end of the screw 38 and the flange 39 of the lever 30.

The subject of the patent.

1. Change of the string index described in patent No. 8014, characterized in that a folding spring-loaded ruler 18 with an axis 22 for rollers 19, 20 and an axis 9 with rollers 7 and 8 are used for clamping the original, for which in shield 4 are made slots 5 and b, for turning which axis 9, there is a ratchet mechanism connected by a cable and levers 28, 29 and 30 with a key 32, and a screw 38 supporting the lever 30 serves for adjusting the cable travel.

2. With the indicator line specified in item 1, use arc 41 to keep the original from falling.

3. With the indicator line indicated in item 1, use of an arc 43 with a screw 44 for attaching the key device A to the cheek L of a typewriter. to the additional patent of E. O. Burkovsky m s. M. Dvoretsky 18782
