Abstract: A device for connecting a heddle frame to a reciprocating lever in a weaving loom which device includes a hook defining a housing in which a ring is selectively seated. The ring is mounted to either the heddle frame or the lever and includes surfaces for cooperatively engaging bearing surfaces defined by the housing of the hook. A lock is provided which is pivotally mounted to the hook and is engageable to retain the ring within the housing of the hook.

Abstract: A connecting device for connecting a motion transmission element to a heddle frame in a weaving loom wherein the connection device includes a tenon member and mortise member which are cooperatively engaged with respect to one another. The tenon member includes a nut mounted to the transmission element, an anchoring block through which the transmission element extends and which cooperates with surfaces of the mortise member, a bush through which the transition element passes and which bush cooperates in rotation with the nut and which also includes a counter-nut for securing the bush against the anchoring block.

Abstract: This device comprises a male member forming tenon screwed on the transmission element and a female member forming mortise fixed on an upright of the frame.

Abstract: This hooking device comprises a ring of substantiAlly polygonal section and an open hook, provided with bearing surfaces arranged to cooperate with the section of the ring and fast with the lever or frame, certain bearing surfaces of the hook being parallel to one another and adapted to ensure, by cooperation with surfaces of the ring likewise parallel to one another, the essential of the transmission of effort between the lever and the heddle frame. The hook is equipped with a member for locking the ring in position engaged in the hook, the bearing zone of the locking member on the ring being located substantially between an axis of articulation of the ring on the frame or on the lever and an axis of articulation of this member on the hook. The locking member is constituted by a lock forming a pivot pin received in a cavity formed in the thickness of the hook, this lock presenting a surface adapted to interact with the ring, of width substantially equal to the width of the ring.

Abstract: A connector for a drawing mechanism including at least one tubular connecting rod of flattened cross section for connecting the connecting rod to a rocking lever of a heddle mechanism wherein the connector includes two cheeks adapted to be disposed on opposite sides of the lever and where at least two generally parallel pins include first ends which are welded to inner faces of the cheeks. The pins include second ends adapted to be connected within the connecting rod and which second ends are spaced from the first ends by a deformable portion of each pin.

Abstract: The ends of two cables associated with a suspension lever in a negative dobby for controlling a common held frame are fixed in a ferrule of an eyelet which is shaped to engage a fastening section provided on a terminal edge of the lever.

Abstract: Adjustable clip elements for assembling oscillating arms of a weaving central system with engaging rods of a drawing system associated with heddle frames of a weaving loom. Each clip element includes a frame having pairs of lateral guides for two pairs of jaw assemblies provided in a slide block and associated with moveable wedges. The wedges are controlled with an adjusting mechanism arranged to urge one wedge towards the base of the slide block while urging the other wedge in the opposite direction.

Abstract: In a dobby drawing device in a weaving loom, the vertical displacement of a heddle frame is obtained with the aid of a single cable which is guided over first and second actuating levers to a set of springs. Two support shafts selectively support the actuating levers so the device may have a lifting or descending action.

Abstract: A drawing mechanism incorporating rocking levers interposed between a weaving mechanism and the heddle frames of a weaving loom wherein each of the rocking levers for coupling the connecting rods includes a lateral element which defines a lubrication conduit joining the interspace of the ball bearings to an opening made in the levers for mounting to a coupling pivot.

Abstract: A drawing device for actuating the heddle frames of a weaving machine of the negative type including rocking levers which guide cables extending from the heddle frame to a return spring system. The rocking levers are mounted on shafts which are shiftable within elongated slots to thereby relax tension on the cables and spring system.

Abstract: In a spring system for dobbies and other weaving mechanisms of the negative type which includes hooking elements, each of the hooking elements includes, parallel to its edges which face the springs, a row of omega-sectioned openings which receive, by a lateral displacement along the axis of the opening, an endpiece of a shape to be seated within the openings.

Abstract: In a spring system for a dobby in a weaving loom, the mobile hooking element which is fixed to a cable for moving a heddle frame includes laterally spaced plates which are slidably engageable with plates of adjacent spring systems to thereby prevent contact of the springs of the adjacent spring systems.

Abstract: A modulator mechanism for actuating textile dobbies in looms which include a cage driven in rotation by the drive shaft of the loom and which have at least two oscillating supports provided with rollers which roll in contact with a fixed cam which is connected to the principal shaft of the dobby. Connecting rods are pivotally attached to the supports and to a web fixed to the dobby shaft so that the dobby shaft is intermittently driven in rotation as the connecting rods are oscillated by the supports.
