    The invention relates to a cam looming mechanism and makes it possible to increase the reliability of its operation. In the shedding mechanism of the weaving machine, the swinging movement of roller levers 4 driven by disk cams 10, 11 on shaft 2 is transmitted through push rods 8, deflecting levers 9 on shafts 23. The deflecting levers 9 have one shoulder 13 and 14 on their input and exit side. The shoulders 13 and 14 are bent relative to the bearing of the arms so that the centers of the hinges 15, 16 at the ends of the shoulders 13 and 14 and the centers of the bearing are essentially located on a straight line, as a result of which the transfer forces in the shedding mechanism at the centers of the hinges 15 and 16 occur moments relative to the centers of the bearings, the resultant of which is located on the axis of the bearing 7. Thus, the deflecting levers rest on the axis 7 without distortions; therefore, operation without wear is ensured with little need for lubricant. 1 hp f-ly, 2 ill.

    Claim
    1. The shed forming mechanism of the loom, comprising dialed and fixed, paired disny cams on the shaft, each pair of which interacts with a lever with two rollers mounted ^ with the possibility of rotation and connected by means of a pushing rod to one of the shoulders of a two-shouldered deflecting lever mounted with rotation by means of a bearing located in its central part, at least one of the arms of which is bent from the plane of the bearing, and at the ends of both arms there is one hinge for movement, while the two-shoulder deflecting levers are mounted on an axis in a projection parallel to it, fan-shaped, and the bending of the shoulders is made so that the step between the centers of the hinges of the shoulders associated with the cams is greater than the step between the centers of the hinges of the opposite shoulders and more than the step between bearings, characterized in that, in order to increase reliability in work by preventing misalignment of bearings, straight lines connecting the centers of the hinges of each of the two-shoulder deflecting levers, and a straight line passing through the center of the base the base and the center of one of the hinges of the same lever form angles with the bearing axis that differ from each other by no more than 8 °.
    . 2. The mechanism according to claim 1, with respect to a font and the fact that the angle of inclination of the straight line connecting the centers of the hinges of each of the two-arm deflecting levers,
