    Abstract: A slay operating mechanism for a loom comprises an operating rod adapted to be pivoted at one end to a slay; a bell crank lever, one arm of which is pivoted to the other end of the operating rod and the central portion of which is pivotally mounted on a shaft; a connecting rod pivoted at one of its ends to a second arm of the bell crank lever; an operating lever pivoted at one end to the other end of the connecting rod and at its other end to fixed structure; a beam pivoted intermediate its ends to the operating lever; two cams cooperating with the ends of the beam, each being mounted on a support shaft; a driving shaft for driving the cams; a Maltese cross for each cam and having at least four radial openings evenly distributed about the periphery thereof, each cam having at least one active face which cooperates, directly or indirectly, with one of the ends of the beam; an arm for each cam and rotatable with the driving shaft and axially movable relative thereto, each arm carrying, at its free end, a roller engageable into one of the openings and, a selection mechanism for selectively positioning the roller either in the plane of the Maltese cross or in a plane parallel to the plane of the Maltese cross; and a cam locking device for locking each cam in the selected position, the locking device being operated by the selection mechanism.
