Abstract: A drawing system for controlling the heddle frames of weaving machines of the negative type wherein a cable associated with a clip element of a spring register is connected to a cable which moves the heddle frame by a tension lever mechanism carried by an oscillating lever whereby the springs of the register may be released from tension in order to facilitate the withdrawal and repositioning thereof.

Abstract: A rotating dobby for weaving looms wherein the oscillating rods which are connected to the heddles are positively and instantaneously retained in a fixed position upon the disengagement of the coupling hooks by way of which the rods are normally engaged with a rotating drive disk.

Abstract: A displacement coder of the differential type wherein, in order to reduce the dimensions thereof, a first disk is rotatably connected to a principal shaft coupled to the shaft which controls the displacement of a mobile member being monitored and a second disk which is coaxially mounted on the principal shaft but which is rotated in a ratio of slightly less than 1 to 1 with respect to the first disk through a driving connection which includes a common pinion and two tooth wheels which wheels are also mounted along the principal shaft.

Abstract: In negative dobbies of the type incorporating swinging lever assemblies to which lever elements are connected and which lever elements support two articulated hooks, retaining members are provided in the form of pivotable locks placed between the bearing face of each hook and the pivot pins by way of which the hooks are mounted to the lever elements.

Abstract: Heddle frames in which each upright includes an opening and a pair of spaced bearing surfaces and wherein each horizontal crosspiece includes a fixed and a movable jaw which extend outwardly therefrom and which jaws are engageable with the bearing surfaces upon adjustment of the movable jaws to thereby secure the horizontal crosspieces to the uprights.

Abstract: A tool-gripping device for remote manipulators, industrial robots and like assemblies which includes a sleeve provided with a movable locking element having an opening therethrough which is traversed by a stepped pin member associated with each tool and wherein the locking element is resiliently urged and operable to engage the pin member at an angle with respect to the longitudinal axis thereof to thereby force the tool into close proximity with the gripping device.

Abstract: Levers with double roller assemblies for positive cam mechanisms for controlling the heddle frames of weaving looms wherein each roller assembly comprises a rotating ring supported on a plurality of roller bearings retained relative thereto on a fixed support mounted to or on extension of the levers. The rings and supports are thus capable of penetrating between the cams of the weaving loom without modifying the axial dimensions of an assembly of such cams.

Abstract: A connection device having two interfitting support pieces for simultaneously connecting multiple fluid circuits. One of the pieces, which bear the male and female elements of the multiple fluid connections to be joined, is provided with a lock capable of rotating and compressing axially against a spring. This lock bears two lateral pins which cooperate with ramps made in a bushing carried by support the other support piece.

Abstract: The present invention relates to dobbies incorporating double swinging levers for weaving looms. In order to simplify the construction of the reading device in the case of synchronized dobbies capable of operating both in reverse motion and in forward motion, there is associated with each selection hook a releasable retaining member which immobilizes it in one or the other of two stable positions of operation, so that the reading device need exert only a fleeting action (pulse) on one or the other of two heels of the hook, whereby no sustained action of the reading device is necessary.

Abstract: The present invention relates to draw lever assemblies mounted on the dobbies and other mechanisms for forming the shed on weaving machines. Between the levers born by the fixed pin there are interposed axial stops, each of which includes two discs profiled to form between them a raceway for balls. The assembly is subjected to a constant axial pressure, furnished for example by an elastically deformable washer.

Abstract: The present invention relates to a hooking device for the semi-automatic connection of the heddle frames of weaving looms with the levers for controlling them. A locking ring is rotatably mounted and has a hexagonal or octogonal profile so that, once correctly oriented by abutment against a ramp, it is closely applied against corresponding bearing surfaces made in the opening of the opposed hook.

Abstract: The present invention relates to fast-fit unions for removably joining pipes, wherein a tubular lock element loaded by a spring carries on its inner wall three teeth offset axially of the union with respect to one another, the central tooth being provided opposite the other two so that, to unlock the two elements of the union, two successive inward displacement maneuvers must be exerted on the lock element, consequently allowing the compressed fluid time in which to be evacuated to the atmosphere.

Abstract: The invention relates to improvements in mechanisms for driving regulators of weaving looms. Between the shaft of the dobby and the chain pinion which drives the regulator of the loom there is interposed a differential reverser whose satellites are borne by a race axially moveable coil. The latter is moveable through the unweaving circuit so that the reverser is automatically actuated during unweaving and causes the regulator and the woven fabric to move backwards while the dobby continues to rotate in the same direction (electronic program).

Abstract: The present invention relates to electromagnetic devices for controlling dobbies and other weaving systems, wherein the control unit which contains the electro-magnets is borne by an oscillating frame on which is mounted an equal number of selectors associated with a spring which tends to move them away from the associated poles of magnetic attraction. Each selector acts selectively on the actuating hooks of the dobby, and a fixed stop ensuring its return into applied position against the magnet upon return into a non-actuating position. The device is applicable to the control of a dobby with double swinging levers or to the control of a rotating dobby.

Abstract: The present invention relates to improvements in rotating dobbies. The control of the coupling pawl for connection to the driving shaft is effected by one of two right-angled pivoting levers actuated in the same zone by push elements of the reading device of the dobby. When a lever engages in a notch in a plate fixed to the eccentric, the nose of the engaged one of the pivoting levers pushes a catch on the pawl which pivots the pawl causing the withdrawal of its finger to release connection with drive from the shaft.

Abstract: The present invention relates to an adjustable fastener for fastening pulling cables to the suspension levers of textile dobbies of the negative type, said fastener being constituted by two parallel side elements which support a pin for the pivoting connection of the fastener to the end of the corresponding suspension lever, a curved lower guide, and an upper stop provided with two forks which are traversed by threaded end pieces fixed to the pulling cables and which form support for adjusting nuts.

Abstract: The present invention relates to safety valve unions wherein the rotating plug is shaped so as to retain when it is in open position the terminal end of the male element which is released when said plug has been brought into closed position. The opposite faces of the boss and of the pivoting lever are shaped to provide an intermediate position in which the plug is closed, the downstream pipe of the male element is decompressed through a channel and a vent in register, and the terminal is still locked in the bore. The invention is more particularly applicable to the hydraulic or pneumatic accessory industry.

Abstract: The invention relates to multiple unions of the type comprising two plates which carry elementary unions and which are brought close together or spaced apart, by force, with the aid of at least one maneuvering device of the rack and pinion type. Initial latching of the two plates is ensured by a bolt-pillar mechanism, the pinions having on the shaft an angular clearance enabling them to remain immobile and to allow unlocking when the handle begins its movement for the separation of the two plates. With this handle are associated locking means which ensure retention thereof in locked position.

Abstract: The present invention relates to the system of angular connection of the eccentric of each element of a dobby either with the shaft or with the corresponding arm. This connection is ensured by a double hook borne by the eccentric and mounted to rock so that one or the other of its noses engages in a notch made in the periphery of a driving device fixed to the shaft, or in a notch in a bead of the arm.
