The invention covers a mechanical device for moving, upwardly and downwardly, the lifters of a weaving machine and comprises two horizontal bars provided, at the respective adjacent sides, with a series of cantilevered parallel teeth inserted into one another and with vertical guides sliding in respective seats fixed to the side walls of the device. Each horizontal bar is connected to a connecting rod which is eccentrically pivoted to a rotating disc by means of a plate. The rotating disc is provided with a graduated sector having a radial slot so that it is possible to vary the movement of the two horizontal bars. Vertical bars are fixed to the horizontal bars and the free end of the vertical bars slides in a guide which is provided on each side wall of the device. The guides have a slanted vertical axis. The vertical bars are preferably of "T" shape.
