    means key 3. On the mounting ring 2 through eccentric bearings 4 an eccentric 5 is placed, to which, in turn, through the next roller bearing 6, a connecting rod 7 is attached. T 8 of the connecting rod are hinged to noBopo-jHOM. the lever 9, which serves to drive a shaft not shown in detail, while the rod 8 of the connecting rod performs the stroke H from position H to E, To connect the eccentric 5 to the drive shaft 1 or to fix the eccentric 5 on the connecting rod 7 serves a connecting wedge 10, which alternately falls into at least one radial groove 11 connected to the shaft 1 or at least one radial groove 12 connected to the connecting rod 7. Between the radial grooves 11 or 12, the connecting wedge 10 is guided through cam surfaces 13 or 14, which are connected to the connecting rod 7 or shaft 1 and prevent the exit of the corresponding radial groove. The switching sleeve 15, which operates according to the program, serves to control the connecting wedge 10. Regardless of the coupling wedge 10 in the eccentric 5, there is a lock wedge 16 that can move approximately opposite to the direction A of the drive shaft 1, the lock wedge is self-closing and comes with -. Responsible to the position of the connecting wedge 10 at least one locking recess 17 interacting with the drive shaft 1 or locking recess 18 interacting with the connecting rod 7. There are control surfaces 19 and 20 or 21 and 22 on the retaining wedge 16 and / or on the stopping recesses 17 or 18 which allow the wedge 16 to be displaced from one of the recesses when the drive shaft 1 is ahead of the eccentric 5 or the eccentric 5 is ahead of the connecting rod 7 and if, accordingly, the other end of the locking wedge 16 is opposite the recess. Between the side grooves 17 and 18, the stopper wedge 16 is also guided from sliding over the cam surfaces.
    The connecting device is designed in such a way that it makes it possible in two displaced 180 positions to attach the eccentric 5 to the drive shaft 1. According to this, the radial grooves 11 and 12, and the tolls and the stop grooves 17 and 18 are pairwise shifted by 180, respectively.
    The radial grooves 11 and locking recesses 17 interacting with the drive shaft 1, as well as the cam surfaces 14 are located on the radial flange 23 of the installation ring 2 Radial flange, 23 simultaneously serving as a lateral restriction of the roller bearing 4.
    The connecting wedge 10 moves- C into the groove 24 in the eccentric 5. The construction is such that the connecting wedge 10 can move parallel to the radius 25 of the drive shaft 1. The connecting wedge 10 has approximately parallel to the direction of movement 26 the connecting surface 27, which interacts with the corresponding the connecting side surface 28 of the radial groove 11. Then the connecting wedge 10 kmWT facing back surface 29, which interacts with the corresponding surface 30 in the eccentric 5. At the same time edinitelnyr wedge 10 are so removed from the radius 25, that the connecting surface 28 of the radial groove 11 is opposed to the support surface 30 on the eccentric 5 at least approximately perpendicular to and approximately equal to it in magnitude. Due to this, an optimal transfer of forces is achieved and the flexural stress of the connecting wedge 10 is prevented.

    A tension spring 31 is placed between the connecting wedge 10 and the eccentric 5, which presses the connecting wedge 10 to the shaft 1 and makes it possible for the connecting wedge 10 to fall into the radial groove 11 of the shaft 1 when the switching sleeve 15 is in the on position. The radial groove 11, which is attached to the shaft 1, has an approximately tangential inlet part 32, which allows smooth engagement of the connecting wedge 10. The pressure spring 31, which serves to this engagement, contributes to this smooth engagement.
    The connecting wedge 10 is provided with a lateral locking cam 33, which cooperates with a corresponding control cam 34 on the switching sleeve 15, in order to make it possible to disengage the connecting wedge 10 from the radial groove 11 of the shaft 1.
    The switching sleeve 15 further overlaps the path of the gripping cam 33. The switching sleeve 15 then has a guide groove 35 in which the gripping cam rotates. The inner side surface 36 of the guide groove 35 includes a control cam 34. The switching sleeve is installed with rotation on a shaft 37 eccentric to the drive shaft 1, however, with an axis parallel to it. The control means 38 serves to swing the switching sleeve 15 by an amount S.
    The connecting wedge 10, with its end facing the shaft 1, enters radial groove 12, which is attached to 7. This radial groove has in turn approximately a tangential inlet part 39 and a sloped lateral surface 40 that facilitates disengagement. Kulakova surface 13 enters the inlet part 39 and ends at the exit surface 40. The guide lateral surface 40, like vi radial groove 12, is located in the ring 41, which is located on the side of the connecting rod 7 and radially protrudes to the drive shaft 1. The ring 41 serves one TERM for supporting rod 7 n roller bearing 6 on the eccentric ring 5. The bolts 42 and pins 43 connected to a connecting rod 7. The bolts 42 and pins 43 may be formed in kache30

    Cut off fuses that are cut when the wedge is locked 10.
    The locking wedge 16 is also located moving in the groove 44 in the eccentric 5, while the direction of movement in the present example is radial with respect to the drive shaft 1. The front side exit surface 45 of the locking wedge 16, which faces the shaft 1, as well as the rear the surface 46, which faces the connecting rod 7, is inclined at an acute angle to the direction of movement 47 of the stopper wedge 16. Due to this, the stopper wedge 16 creates a wedge action so that any gap is eliminated when connecting the connecting wedge 10, ited 45 facing the shaft 1, cha- STI locking wedge 16 and the surface 48 of the locking recesses 17 at least parallel to the mean radius of the recess 25 between the retainer 17 and the radial groove 11, whereby the optimum distribution of forces is possible. The width B of the locking recess 17 is smaller than the width B of the connecting wedge 10, thereby preventing the jumper of the connecting wedge 10 from falling into the recess of the first 7.
    In an eccentric 5 with jiggle, a latch 49 is installed, which is pressed against a retaining wedge 16 by means of a spring 50. When the retaining wedge 16 pops out of the retaining recess 17, then the latch 49 operates approximately. 51 approximately perpendicular to the retaining wedge 16, created by By this means, friction prevents undesirable movement of the locking wedge 16 in the direction of the locking recess 27 of the shaft 1. If the locking wedge 16 conversely jumped into the locking notch 16, then the spout 51 acts into the recess 52 of the locking wedge 16 and presses the locking wedge 16 to the stopper second recess 17. Thereby prevented undesirable skakivanie You are a locking wedge 16 of stpornoy recess 17. The latch 49 together with the locking wedge 16 and the coupling wedge 10 is held in the eccentric 5 by means of a cover 53. The cover is attached by screws 54 to the eccentric 5.
    The recess notch 18, which interacts with the connecting rod 7, also has 36
    Placed in the ring 55, which is provided on the back side of the connecting rod 7 and is designed respectively to the ring 41, which contains a radial groove 12 of the connecting wedge 10. The ring 55 also contains a cam surface 13 serving as a guide for the wedge 16. hold rod 7, as well as roller bearing 6 on the eccentric 5.
    Unlike the presented form of use, it is also possible to connect the rings 41 and 55 not with the help of the connecting rod 7, but to perform concentrically with the drive shaft 1 and place it motionless on the housing not shown. You can also lock the recess 18 directly combined with the ring 41, which contains a radial groove 12.
    In the connecting device (FIG. 5, shaft 1 rotates freely, and the connecting wedge 10 drops into the radial groove 12, and the stopper wedge 16 — into the stopper notch 18, which are suitably attached to the connecting rod 7. Due to this, the eccentric 5 stops at the connecting rod. 7. The switching sleeve 15 does not need to perform any functions here, since the connecting wedge 10 with its internal end side is adjacent to the shaft 1 and thereby locks out of jumping out of the radial groove 12 on the connecting rod 7.
    , FIG. 1, as well as in FIG. 6-8 shows the preferred control means which is fixedly mounted on the machine bed 56 and connected to the drive roller 57, on which the lever 58 is fixed, installed with the possibility of swinging in time to the machine’s shedding mechanism, which has a bearing surface 59, which interacts with the end 60 of the step of the switching sleeve 15 and moves the switching sleeve against the action of the spring 61 from the first on position S in the X direction to the second on position Sg. On the rocker arm 58 by means of the pin 62, the latch 63 is pivotally attached and just on the diameter of the support surface 59. This latch is opposite the switching sleeve 15 and communicates with the spout 64 with the notch 65 of the switching sleeve 15. The latch 63 has wedges 61, the Switching sleeve 15, thereby geometric clamping is rescued from the possible load on the connecting wedge 10. In this switching on position, the control cam 34 of the switching sleeve 15 releases the connecting wedge 10 | through the gripping cam 33 so that A dividing wedge 10 is included (Fig. 8). The eccentric 5 captures the connecting wedge 10 and the locking wedge 16, as well as the shaft 1, rather than the connecting wedge 10 by means of a switching control cam
    Vuya surface 66, which interacts with the wedge surface 67 of the switching sleeve, when the latch and n-. The switching sleeve is moved relative to the other. Further on the latch 63 there is an oblong hole 68 ,. the pin 69 is connected to the intermediate lever 70, which is mounted on the fixed pin 71 and pressed against the latch 63 by means of the spring 72.
    The intermediate lever 70 interacts with the completed electromagnetic control means 73, which is set relative to the intermediate sleeve 15, is again turned off in the front lever 70 by means of adjusting screws 74. The control pulses are fed to the control means 73 from a pattern-forming device not shown, such as an electronic memory magnetic tape control devices or the like. through the wire 75. The holding force of the electromagnetic control means 73 is greater than that generated by the spring
    72 is clamped on the latch 63 when the intermediate lever 70 is adjacent to the control means 73. However, the tension created by the prulse 72 can be greater or less than the pulling force of the lazy electromagnetic control means 73 when the latch 63 is attached to the switching sleeve 15, i.e. the intermediate lever 70 is distant from the means
    73 controls .35 The swing arm 58 is still connected
    with a stop 76, which cooperates with the protrusion 77 of the switching sleeve 15, if the swing arm 58 and the switching sleeve 15 occupy the first 40 switching position S, (Fig. 9).
    Operates the connecting device as follows.

    H. If the eccentric 5 with the only wedge 10 is in the H position (Fig. 5), the control cam 34 of the switching sleeve 15 would not release the coupling wedge 10 and therefore the connecting wedge remains in the off position. The water shaft 1 rotates open further , (figure 5),
    If the unit now rotates with the possibility of swinging the chamfer 58 to the right, then the switching plug 15 through the thrust surface 59 moves against the action of the spring 6 1 in the X direction to the middle
    (Fig.6). If sreds
    m
    73 of the control is not turned on, then the latch 63, under the action of tensioning the spring 42, abuts the switching sleeve 15 and can, with its nose 64, jump into the recess 65. If the rotary lever 58 rotates further, the latch 63 is opposite to the direction of movement of the switch sleeve 15 moves to the size and, due to which the wedge surface 66 of the latch 63 finds on the Kli a new surface 67 of the switching sleeve 15 and the latch 63 thereby leads the intermediate lever 70 to the attachment to the control means 73 (Fig. 7). If the control means 73 is turned on, the intermediate lever 70 continues to contact the control means and the switching sleeve 15 returns with the reverse rotation of the lever 58 in the direction Y to the first on position S, (FIG.
    In the coupling device (Fig. 45-8), the swing arm 58 and the switching sleeve 15 occupy the first, left, on position S ,. The control means 73 is turned on and holds the intermediate lever 70 against the tension of the spring 50 of the girdle 72, whereby the latch 63 of the lift and the nose 64 cannot interact with the notch 65 of the switching sleeve 15. In this position, the locking stop 76 of the swinging lever 55 55 abuts to the protrusion 77 of the switching sleeve 15 and prevents the switching sleeve from moving away from the supporting surface 59 against the action of the spring 61. The switching sleeve 15 thereby with geometrical clamping is protected against possible loading of the connecting wedge 10. In this the switching position of the control cam 34 of the switching sleeve 15 releases the connecting wedge 10 | through the gripping cam 33 so that the connecting wedge 10 is turned on (Fig. 8). The eccentric 5 is caught by the connecting wedge 10 and the locking wedge 16, as well as by the shaft 1, and the connecting wedge 10 is switched off again by means of the control cam of the switching sleeve 15.
     - bushing sleeve 15 is turned off again.

    H. If the eccentric 5 with the connecting wedge 10 is in the H position (Fig. 5), the control cam 34 of the switching sleeve 15 would not release the connecting wedge 10 and therefore the connecting wedge remains in the off position. The drive shaft 1 rotates further open, (figure 5),
    If the lever 58, which is now installed with the possibility of swinging, is rotated to the right, the switching sleeve 15 through the stop surface 59 moves against the action of the spring 6 1 in the X direction to the middle
    (Fig.6). If a means
    m
    S position
    73 of the control is not turned on, then the latch 63 under the tension of the spring 42 abuts the switching sleeve 15 and can, with its nose 64, jump into the recess 65. If the swing-mounted lever 58 rotates further, then the latch 63 against the direction of movement of the switching sleeve 15 it retreats by and, so that the wedge surface 66 of the latch 63 locates the wedge surface 67 of the switching sleeve 15 and the latch 63 thereby brings the intermediate lever 70 to fit, to the control means 73 (Fig. 7). If the control means 73 is turned on, then the intermediate lever 70 continues to contact the control means and the switching sleeve 15 returns with the reverse rotation of the lever 58 in the direction Y to the first on position S, (Fig. 8)
    If in the middle position 5 "the control means 73 is not turned on, then the latch 63 under the action of the spring 72 falls when the lever 58 reverses the lever 58 into engagement with the switching sleeve 15 so that the nose 64 of the latch
    63 may snap into the recess of the step of the switching sleeve 15. When the lever 58 is swung back to the first switching position S, the latch 63 is out of the intermediate lever 70. Moreover, the intermediate sleeve 15 should not perform swing movements if it is held in the second position.
    there is no oncoming movement and penetrates the j of the inclusion S, i.e. when not on, by coupling with the switching sleeve 15 against the action of the spring 61 to the second closing position S, j, (Fig. 1). By this the connecting rod of the control means.
    The proposed device allows an increase in the reliability of operation due to the simplicity of the connections and the control means with the connecting device.
    H lies in the H position, or remains in the N. position, if it was already in this position before the switching process. The adhesion between the latch 63 through the nose 64 with the recess 65 of the step of the switching sleeve 15 creates a connection with a geometric circuit, which counteracts the possible force of the connection of the connecting wedge 10 so that false inclusions are excluded. 20
    In the exemplary embodiment of the control device (Figs. 1, 6-8), there is an advantage that the decision to switch on occurs in the average switching position 5 so that the turning path of the drive plate 38 can remain small, which has a positive effect on the increase in the working speed.
