- a hooking nut forming at least two surfaces intended to cooperate with the contact surfaces of the mortise member, this nut being provided with a through hole for passage of the transmission and reception element, with the possibility of rotation, nut; a sleeve provided with a central bore for passage of the transmission element and capable of driving the nut in rotation around the element. transmission, through the drilling of the nut and
- the dimensions of the nut can be provided so that its surfaces intended to cooperate with the mortise member are relatively large, while the adjustment of the longitudinal position of the tenon member does not impose not to make the nut undergo a rotational movement around the threaded rod constituting the transmission element, which would not be compatible with the usual implantation density of frames in a loom.
- the nut and the sleeve make it possible to obtain the adjustment of the position of the nut along the element of transmission without inducing rotation of this nut, the nut thus being able to maintain a suitable orientation with respect to the mortise element carried by the frame.
- the device incorporates one or more of the following characteristics:
- the nut and the socket are provided with reliefs of corresponding shapes allowing interconnection of the nut and the socket.
- the socket is provided with a polygonal section head, which allows it to be driven in rotation by means of a usual wrench.
- the piercing of the nut comprises two internal shoulders respectively facing the two outlets of this piercing and intended to cooperate respectively with corresponding surfaces of the nut and of the socket. These two internal shoulders make it possible to control the position of the nut along the transmission element using the nut and the socket.
- the nut is provided with at least one protrusion adapted to be engaged 'in the slot of the mortise member. This protuberance ensures a suitable positioning of the nut relative to the mortise member and the environment of the frame.
- the nut is provided with an extension directed opposite the mortise member when the tenon member is in place in 1 Mortise member, this extension being able to be engaged in a guide and retaining slide of the post-organ.
- this extension advantageously has a generally T-shaped cross section.
- the invention also relates to a drive assembly for heald frames of a loom which comprises at least one device as described above and a set guides capable of each receiving an extension of the nut of such a device, each guide having, in cross section, a shape such that it opposes extraction of the extension in a direction generally perpendicular to the direction of sliding of the extension in the guide considered.
- the guide is movable according to a direction generally perpendicular to the sliding direction, which makes it possible to control a movement of introduction / extraction of the organ-tenon relative to one organ-mortise.
- the invention finally relates to a weaving loom equipped with a device or assembly as described above. Such a loom is easier to use, especially during changes of frameworks which must be regularly carried out during the use of such a loom.
- the invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a device and of an assembly in accordance with its principle implemented in a loom also in accordance with the invention, given solely by way of example and made with reference to the appended drawings in which:
- Figure 1 is an exploded perspective view of a device according to the invention

- FIG. 3 is an exploded perspective view, on a larger scale and with partial section, of the tenon element
- FIG. 4 is a section along line IV-IV in Figure 2 and
- FIG. 5 is a schematic representation of principle of part of a weaving loom according to one invention.
- a heald frame 1 of a loom M is intended to be driven by a dobby 2 by means of movement transmission elements which comprise a connecting rod 3 for connection between the dobby and an elbow lever 4, this lever and this connecting rod being connected by a synchronism bar 5 to a second bent lever not shown and arranged on the other side of the loom M.
- the bent lever 4 is connected by a connecting rod 6 to a slide 7 guided by rails 8 and 8 '.
- the slider is itself connected to an elongated force transmission element which is formed by a threaded rod 9 on at least part of his height .
- the upright 12 is cut by a longitudinal groove 13 with a rounded bottom allowing the reception of the rod 9.
- the upright 12 is also provided with three through holes 14 allowing the mounting of a fastener 20 forming a mortise and which consists of two vertical flanges 21 and 22 between which is a spacer 23.
- the flanges 21 and 22 are provided with three holes 24 provided to be aligned with the holes 14 during mounting of the fastener 20 on the frame 1. Screws 25 or rivets make it possible to immobilize the fastener 20 on the frame 1 by crossing the orifices 14 and 24.
- Each flange 21 and 22 is cut out from a notch 26 lr respectively 26 2 , oriented on the side of the groove 13 when the fastener 20 is mounted on the frame 1.
- the main direction of the lateral upright 12 of the frame is noted XX ′.
- the notches 26 x and 26 2 are respectively d bounded by the lower edges 27 and upper edges 28, these edges 27 and 28 being generally perpendicular to the direction XX ', that is to say generally horizontal, in use configuration the art.
- the volume defined between the flanges 21 and 22 is noted 29. This elongated volume constitutes a slot for partial reception of the rod 9, as is apparent from the explanations which follow.
- a set 40 forming a tenon is provided to be mounted on the rod 9 and partially introduced into the notches 26- L and 26 2 to interact with the edges 27 and 28.
- This assembly 40 comprises a nut 41 intended to be screwed onto a threaded part 9a of the rod 9.
- This nut 41 has an external radial surface 42 which is generally cylindrical and has two teeth 43 and 44 each extending in a direction generally parallel to a central axis X 1 of the rod 9 when the nut 41 is in place on this rod.
- the assembly 40 also includes a nut 45 provided with a through bore 46, which is not tapped and the dimensions are such that the nut 45 can freely slide around the threaded part 9a.
- the internal radial surface of the bore 46 is provided with a flange 47 defining two shoulders 48, 49 respectively oriented towards the lower outlet 46a and towards the upper outlet 46b of the bore 46.
- the shoulder 48 is supported on the upper surface 41a of the nut 41.
- the nut 45 is provided with a protrusion 50 whose width L 50 is slightly less than the width 1 29 of the slot 29, so that this protuberance 50 can be engaged in the slot 29 of the fastener 20.
- the protuberance 50 is interrupted by the bore 46.
- On either side of the protrusion 50 are defined two surfaces 51 and 52 intended to come into abutment against the upper edges 28 of the notches 26 1 and 26 2 .
- the length L of the surfaces 51 and 52 is relatively large which allows a distributed support of the nut 45 on the edges 28.
- the lower surface 53 of the nut 45 that is to say the surface opposite to the surfaces 51 and 52 , constitutes a bearing surface on the edges 27 of the notches 26 ! and 26 2 .
- the nut 45 is also provided with an extension 54 with a generally T-shaped cross section which is intended to be engaged in a guide in the form of a slide 100 defining a groove 101 with an internal section generally in a T shape.
- the minimum width 1 101 of the groove 101 is less than the maximum width 1 54 of the extension 54, so that once engaged in the groove 101, the extension 54 cannot be moved in the plane of the frame in a direction YY 'perpendicular to its direction X 2 of sliding in the guide 100.
- a bush 55 also belongs to the assembly 40 and is provided with a central bore 56 of sufficient diameter to allow the bush 55 to slide around the part 9a of the rod 9.
- the sleeve 55 is provided with an external radial flange 57 intended to come into abutment against the shoulder 49 when the lower part 58 of the flange 57 is engaged in the bore 46.
- the part 58 is provided with teeth 59 and 60 able to come into engagement with the teeth 43 and 44 of the nut 41, through the bore 46, which allows the elements 41 and 55 to be joined in rotation.
- the socket 55 is also provided with a hexagonal head 61 allowing it to be maneuvered using a conventional key.
- a lock nut 62 is also provided in the assembly 40 to be screwed onto the part 9a of the rod 9 in order to block the socket 55 against the nut 45 and the nut 41.
- the tenon member 40 therefore comprises a formed assembly elements 41, 45, 55 and 62. Thanks to the dimensions of the surfaces 51, 52 and 53, the support of the tenon member 40 against the mortise member 20 is distributed over relatively large areas, which avoids a matting of surfaces 51 to 53 or edges 27 and 28. •
- the adjustment of the position of the assembly 40 along the rod 9 is micrometric and carried out by means of the nut 41 on which the sleeve 45 rests.
- the adjustment of the longitudinal position of the assembly 40 relative to the rod 9 takes place without the nut 45 being rotated, which keeps the extension 54 in place in the guide 100 and avoids interference between adjacent tenon members in a loom.
- the elements 50 and 54 both have the function of guaranteeing the correct positioning of the nut 45 relative to the slot 29 and, as a variant, only one of these elements can be used on a nut ' of a device according to the invention.
- the invention has the particular advantage that, in the case where a limited number of heald frames is used for weaving a piece of fabric, the rods 9 which are not associated with frames are kept in positions substantially vertical by the cooperation of the extensions 54 and the guides 100, so that they cannot fall or catch on.
- each guide 100 can be mounted on a support 102 articulated around an axis 103 relative to an element 104 of the frame of the loom M, which makes it possible to envisage a transverse movement F by relative to the direction X-X ', that is to say a movement of approach or distance of the guides 100 and of the members 40 of the loom relative to the mortise organs 20 according to the direction YY'.
- a single support 102 can be used for all the guides 100 of a loom.
- the guide rails 8 and 8 ′ can be supported by the support 102 which allows each rod 9 to pivot over its entire length.
- a frame drive assembly in the weaving loom in accordance with the invention allows easy and simultaneous positioning of the tenon members associated with the movement transmission elements in the mortise members associated with different frames , possibly with the assistance of an engine.
- the invention has been represented with a positive dobby, it is of course applicable with a negative dobby, as known, for example, from EP-A-0 297 003 and, more generally in any weaving loom in which the frames of rails must be set in motion, for example with a cam mechanism.
