    The invention relates to the improvement of the Gatersley helix carriage designed to form the throat during the operation of the loom. Closest to the invention to the technical essence is a locking carriage of a weaving machine, comprising a balance bar, a hinge connected in the middle part with an exit arm connected kinematically connected with the heddle frame of the machine, installed with the possibility of alternately contacting the ends with movable and stationary stops and the hinged link with a hook. mounted and disengaged with fixed and movable blades, the latter of which are connected with the drive and mounted with the possibility of swinging The arc is relative to the horizontal axis, located at an equal distance from the keys, and the means of rotating the movable and stationary knives for selecting and forming a gap during the switching period between knives and hooks. The lack of a carriage is the unreliable operation of the means for rotating the movable and stationary knives, ensuring the formation and selection of the gap when switching between hooks and knives. The aim of the invention is to increase the reliability of the carriage in operation. This object is achieved in that Remy zopodemnoy carriage comprising a balance bar pivotally connected in the middle of a kinematically communication zannm a heald frame machine output arm and mounted for alternately contacting ends with movable and Nepo vizhnmi stops and pivotally communication Zannah hook mounted with the possibility of engagement and disengagement with fixed and movable blades, the latter of which are connected with the drive and are installed with the possibility of swinging along an arc about a horizontal axis, are located at equal distance from the hooks, and means of rotation of the movable and fixed knives to select and form a gap during the switching period between knives and hooks, each of the means of turning the corresponding knives is made in the form of a hinged 822 parallelogram and has a shaft connected to the drive with attached to one end with one shoulder levers, intermediate one shoulder levers, 3aKpenjreHHHe with one end on the respective knives, and rods, each of which is hinged at its ends with the free ends of the corresponding single-arm levers, with the length of each bar being shorter than the distance from the basements of the controls of the fixed and movable knives mounted coaxially adjacent to one another. I-, FIG. 1 shows a diagram of a heald carriage; in fig. 2 lever mechanisms for rotating movable knives; in fig. 3 - lever mechanisms for rotation of motionless knives; in fig. A is a device for moving the helix carriage hooks. The remisable lifting carriage is a mechanical arrangement by which the base of the warp is formed during the operation of the loom in accordance with the interlacing pattern specified by punched tape, interacting with the read needles. The device (Fig. 1) contains a readout node A, a control node B and a perforated paper tape C. The read node A contains reading needles 1, stop rods 2, pressure rails 3 and swing levers A. The control node B contains vertical control rods 5, kinematically associated with horizontal needles 6, which are in contact with the swinging arms 4 and their springs spring-loaded in the direction. The vertical bars 5 have hook-shaped upper ends 8 for engaging the stops 9. In addition, the bars 5 are kinematically connected with hooks 10 pivotally connected at points 10 with the ends of the balance bar 11, which in turn is pivotally connected at point 11 with an output lever 12, connected by means of a system of 13 levers with a heddle. Hooks 10 are installed with the possibility of interaction (engagement and disengagement) with fixed knives 14 and movable knives 15, as well as with the possibility of interaction with lowering strips 16 and lifting lugs 17 fixed on vertical rods 5. Movable knives 15 have a power drive ensuring their movement axes along circular arcs with a center located on the axis of shaft 18, which is the output element of said power drive. The knives 14 and 15 are equipped with lever mechanisms to form and select a gap between them and the hooks 10 during the switching process. The lever mechanisms (Fig. 2) serve to form and select a gap between the movable knives 15 and the keys 10. These mechanisms consist of rigidly connected knives 15 single-shouldered levers 19, which are connected to single-armed levers 21 fixedly fixed by knives 20. on coaxially mounted shafts 22 and 23. At the same time, these mechanisms take the form of a hinged parallelogram with vertices located on the axes of the hinges of connecting pipes 20, knives 19 and shaft 18. Levering mechanisms (Fig. 3) serve to form and select ores between fixed knives 14 and hooks 1 These mechanisms consist of 14 single-arm levers 24 rigidly connected to the blades, which are connected with single-arm levers 26 fixed to the shafts 22 and 23 and attached to levers 24. Lever mechanisms 24–26 also form a wavy joint of a parallelogram. This design of lever mechanisms in the form of articulated parallelograms simplifies manufacture and ensures reliable operation. The device (Fig. 4) serves to lower the hooks 10. In this device, the slats 16 are attached to the rods 27 located in vertical guides (not shown in Fig. 4). On the shafts 22 and 23, the one-arm levers 28 are fixedly attached, which by means of the pullers 29 are hingedly connected to the two-arm levers 30 rotatably mounted on the shaft 18 and pivotally connected to the rods 27. The slats 16 are covered with impact-resistant material 31 for contacting with hooks 10. During the operation of the loom, the shafts 22 and 23 at certain times according to the cyclic diagram make swinging movements around their axes. This movement through the levers 21, the ti gi 20, the tillers 19 are transmitted by the movable knife 15, which also make a turn about its axis, forming a gap, which is necessary to engage or disengage the hook 10 with the said knife. After the switching process, the knife is rotated in the opposite direction to select this gap in order to provide maximum gaps in the power kinematic chain during the period of the heddle movement. Similarly, using the shafts 22 and 23 of the levers 26, tg 25 and the levers 24, the fixed knives 14 are rotated, and the same targets, i.e. improving the dynamics of the carriage. In addition, from the shafts 22 and 23. .l jf j acijiL ji f. l, p hp using the levers 28, t g 29 levers 30 and vertical rods 27, the movement is transmitted to the flames 16, which act with their shock-resistant lining 31 on the hooks. 10, withdrawing them from 3 engagement with stationary knives 14 and engaging with lodvizhnimi knives 15 The comparative simplicity of the design allows the effective carriage to form gaps between hooks and knives before x engagement and during disengagement, as well as a full sampling of this azor for the duration of the working engagement. rS G5 C / 4 70 ig.2
