Description

La présente invention a trait aux ratières et autres mécaniques pour la formation de la foule sur les machines à tisser, et elle vise plus par­ticulièrement l'accouplement des cadres de lisses sur les câbles ou au­tres éléments de transmission destinés à leur manoeuvre.The present invention relates to dobbies and other mechanical devices for training the crowd on weaving machines, and it relates more particularly to the coupling of heald frames on cables or other transmission elements intended for their operation.

On sait que dans les mécaniques associées à un système de tirage du type négatif tel que schématiquement illustré à la fig. 1 du dessin annexé, l'une des extrémités de chacun des câbles de manoeuvre a est générale­ment amarée à l'un des leviers oscillants de tirage b de la mécanique c, tandis que l'extrémité opposée est reliée, à travers un secteur pivotant d, à un registre de ressorts e propre à ramener le cadre de lisses correspondant f à la position de repos après qu'il ait été positivement déplacé par ladite mécanique c. Entre ses deux points de fixation, le câble a, renvoyé par une poulie inférieure de détour g, présente un brin orienté de manière substantiellement verticale qui longe le montant du cadre f envisagé.We know that in the mechanics associated with a negative type pulling system as schematically illustrated in FIG. 1 of the accompanying drawing, one end of each of the operating cables a is generally moored to one of the oscillating draw levers b of the mechanism c , while the opposite end is connected, through a pivoting sector d , to a register of springs e suitable for bringing the heald frame corresponding f to the rest position after it has been positively displaced by said mechanism c . Between its two fixing points, the cable a , returned by a lower detour pulley g , has a strand oriented substantially vertically along the amount of the frame f envisaged.

Dans certains cas, chaque cadre de lisses f est suspendu à ses deux sec­teurs pivotants latéraux au moyen de biellettes articulées, mais dans d'autres applications c'est le montant du cadre qui est fixé au brin vetical du câble a, sans aucune articulation, à la manière illustrée en fig. 1. C'est à ce dernier mode de montage que se réfère la présente in­vention.In some cases, each heald frame f is suspended from its two lateral pivoting sectors by means of articulated links, but in other applications it is the amount of the frame which is fixed to the vetical strand of the cable a , without any articulation, as illustrated in fig. 1. It is to this latter mounting method that the present invention refers.

L'expérience démontre que les opérations de montage et de démontage des cadres de lisses sont malaisées. Les montants de chaque cadre sont géné­ralement fixés aux cables par des mécanismes de colliers ou de brides à vis qui sont de manoeuvre difficile. On a bien proposé des systèmes d'assemblage faisant appel à des organes mâles et femelles en forme de tenon et de mortaise, mais les solutions structurelles adoptées restent encore de mise en oeuvre relativement complexe et de fiabilité réduite.Experience shows that the assembly and disassembly operations of heald frames are difficult. The uprights of each frame are generally fixed to the cables by mechanisms of collars or screw flanges which are difficult to maneuver. Assembly systems have been proposed using male and female bodies in the shape of a tenon and a mortise, but the structural solutions adopted are still relatively complex to use and of reduced reliability.

C'est à ces inconvénients qu'entend principalement remédier la présente invention, laquelle consiste, dans le concept d'un assemblage à l'aide d'organes en forme de tenon et de mortaise qui sont rendus solidaires les uns du câble, les autres des montants du cadre afin de se faire face suivant un même plan orienté de manière substantiellement verticale, à avoir recours à des organes qui sont fendus parallèlement au plan du cadre afin de ménager, de part et d'autre du câble, des surfaces de contact entre les tenons et les mortaises pour la transmission des efforts.It is to these drawbacks that the present invention mainly intends to remedy, which consists, in the concept of an assembly using tenon-shaped and mortise-shaped members which are made integral one with the cable, the other uprights of the frame in order to face each other in the same plane oriented substantially vertically, to have recourse to members which are split parallel to the plane of the frame in order to provide, on either side of the cable, surfaces of contact between the tenons and the mortises for the transmission of forces.

On conçoit qu'une telle structure évite tout porte-à-faux entre les ef­forts et les surfaces d'application de ces efforts dans le système d'ac­couplement, de telle sorte que les deux organes conjugués en forme de tenon et de mortaise ne nécessitent aucune fixation réciproque, leur emboîtement à jeu réduit étant suffisant pour assurer à lui seul la transmission des efforts de tirage.It is understood that such a structure avoids any overhang between the forces and the surfaces for applying these forces in the coupling system, so that the two conjugate members in the shape of a tenon and a mortise do not require no reciprocal fixing, their interlocking with reduced clearance being sufficient to ensure the transmission of pulling forces on its own.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

En fig. 2 à 5, la référence 1 désigne l'un des deux montants d'un cadre de lisses classique. Contre ce montant 1, on a rapporté une fourche 2 dont l'ouverture 2a est orientée horizontalement vers l'extérieur du cadre. Cette ouverture 2a définit deux branches superposées, chacune de ces branches étant découpée d'une fente verticale 2b dont le fond pré­sente en section un profil semi-cylindrique.In fig. 2 to 5, the reference 1 designates one of the two uprights of a conventional heald frame. Against this upright 1, a fork 2 has been reported, the opening 2 a of which is oriented horizontally towards the outside of the frame. This opening 2 has defined two superimposed branches, each branch being cut a vertical slot 2 b whose bottom has in section a semi-cylindrical profile.

On comprend que cette fourche 2 constitue un organe femelle en forme de mortaise, propre à accueillir dans son ouverture 2a un tenon formé par l'extrémité 3a d'un organe mâle 3, creusé d'un logement vertical 3b ouvert à ses deux extrémités. Dans ce logement 3b sont montés un mors 4 et deux poussoirs 5 reliés l'un à l'autre par une vis de serrage 6 ; comme mieux montré en fig. 4, le mors 4 présente, à l'oppose d'une face verticale d'appui 4a à section semi-cylindrique, deux facettes obliques opposées 4b qui sont destinées à coopérer avec une rampe 5a prévue sur le côté de chaque poussoir 5.It is understood that this fork 2 constitutes a female member in the form of a mortise, suitable for accommodating in its opening 2 has a stud formed by the end 3 a of a male member 3, hollowed out of a vertical housing 3 b open to its two ends. In this housing 3 b are mounted a jaw 4 and two pushers 5 connected to each other by a clamping screw 6; as best shown in fig. 4, the jaw 4 has, opposite a vertical support face 4 a with semi-cylindrical section, two opposite oblique facets 4 b which are intended to cooperate with a ramp 5 a provided on the side of each pusher 5.

L'un des poussoirs 5 est creusé d'un alésage vertical 5b traversé par la vis 6 qui vient coopérer avec un taraudage vertical analogue 5b du se­cond poussoir, de telle sorte que la manoeuvre de cette vis 6 assure le rapprochement desdits poussoirs qui tendent ainsi à chasser horizontale­ment le mors 4 à l'intérieur du logement 3b.One of the pushers 5 is hollowed out with a vertical bore 5b crossed by the screw 6 which cooperates with a similar vertical tapping 5b of the second pushbutton, so that the operation of this screw 6 ensures the bringing together of said pushers which thus tend to expel the jaw 4 horizontally inside the housing 3 b .

Ce logement 3b est traversé par une tige verticale 7 qui, à la façon en soi connue dans les systèmes du type négatif pour le tirage des cadres de lisses, interrompt au niveau du dispositif d'accouplement le câble attaché à l'un des leviers de la ratière ou autre mécanique analogue, les extrémités de ladite tige 7 étant serties aux deux extrémités du câble envisagé. On conçoit que si cette tige 7 est insérée entre le fond du logement 3b et la face d'appui 4a du mors 4, la manoeuvre de la vis 6 assure le blocage axial et latéral de ladite tige sur l'organe en forme de tenon 3, tout en permettant le réglage précis de cet organe vis-à-vis de l'ouverture de la fourche 2.This housing 3b is crossed by a vertical rod 7 which, in the manner known per se in systems of the negative type for pulling heald frames, interrupts at the level of the coupling device the cable attached to one of the levers dobby or other similar mechanical, the ends of said rod 7 being crimped at the two ends of the envisaged cable. It is understood that if this rod 7 is inserted between the bottom of the housing 3 b and the bearing face 4 a of the jaw 4, the operation of the screw 6 ensures the axial and lateral locking of said rod on the member in the form of pin 3, while allowing precise adjustment of this member with respect to the opening of the fork 2.

On observera que le rayon du fond des deux fentes 2b de cette fourche, celui du fond du logement 3b qui est tourné en direction de l'extrémité 3a de l'organe mâle 3, et celui de la face d'appui 4a du mors 4 sont substantiellement égaux, à un très léger jeu près, au rayon de la tige 7, comme cela apparaît bien en fig. 2 et 3. Par ailleurs, les bords horizontaux de l'ouverture 2a de la fourche 2 sont orientés de manière strictement parallèle et leur écartement est égal, à un très léger jeu près, à la hauteur de l'extrémité 3a de l'organe mâle 3.It will be observed that the radius of the bottom of the two slots 2 b of this fork, that of the bottom of the housing 3 b which is turned towards the end 3 a of the male member 3, and that of the bearing face 4 has jaws 4 are substantially equal, with very little play, to the radius of the rod 7, as can be seen in FIG. 2 and 3. Furthermore, the horizontal edges of the opening 2 a of the fork 2 are oriented in a strictly parallel manner and their spacing is equal, with a very slight clearance, at the height of the end 3 a of the male organ 3.

Dans ces conditions, cette extrémité 3a vient s'engager de manière étroite à l'intérieur de l'ouverture 2a, pratiquement sans jeu. La tige 7 s'applique parfaitement dans le fond des fentes 2b qu'elle traverse verticalement, si bien qu'on obtient un emboîtement précis et stable, dans lequel l'effort transmis passe substantiellement par le centre des surfaces en contact, lesquelles surfaces de contact, mises en relief en fig. 5 par des parties en grisé, sont disposées de part et d'autre de l'axe de la tige 7. On évite de la sorte toute création de couple de basculement, si bien qu'on peut se dispenser d'une fixation mutuelle des organes 2 et 3 à l'aide de vis ou autres pièces séparées, et ce quelle que soit l'importance de l'effort à développer pour la manoeuvre verti­cale du cadre de lisses envisagé.Under these conditions, this end 3 a engages narrowly inside the opening 2 a , practically without play. The rod 7 is applied perfectly in the bottom of the slots 2 b which it crosses vertically, so that a precise and stable interlocking is obtained, in which the transmitted force passes substantially through the center of the contact surfaces, which contact surfaces, highlighted in FIG. 5 by shaded parts, are arranged on either side of the axis of the rod 7. This avoids any creation of tilting torque, so that one can dispense with a mutual fixing of organs 2 and 3 using screws or other separate parts, regardless of the amount of effort to develop for the vertical operation of the heald frame envisaged.

En vue d'éviter tout déplacement latéral parasite de l'organe mâle 3 au cours du fonctionnement du métier à tisser, on fait comporter à cet organe, à l'opposé de l'extrémité 3a, un talon 3c dont la queue est engagée à jeu réduit à l'intérieur de l'ouverture 8a d'une coulisse verticale 8 à section en U, fixée à demeure contre la structure du métier sur chacun des côtés des cadres de lisses de celui-ci. Cette coulisse 8 est positionnée de façon à ne pas gêner le montage et le démontage des cadres de lisses sur les tiges 7, ces opérations étant effectuées en déplaçant vers l'extérieur les câbles qui supportent lesdites tiges, à la manière illustrée en fig. 6 et 7. Bien entendu, ces opérations se trouvent simplifiées du fait qu'elle ne nécessitent aucune manoeuvre de vis ou autre organe de fixation au niveau de chaque dispositif d'accouplement.In order to avoid any parasitic lateral displacement of the male member 3 during the operation of the weaving loom, this member is made to have, opposite the end 3 a , a heel 3 c whose tail is engaged with reduced clearance inside the opening 8 has a vertical slide 8 with a U-section, fixed permanently against the structure of the loom on each of the sides of the heald frames thereof. This slide 8 is positioned so as not to hinder the mounting and dismounting of the heald frames on the rods 7, these operations being carried out by moving the cables which support said rods outwards, in the manner illustrated in FIG. 6 and 7. Of course, these operations are simplified by the fact that they do not require any operation of a screw or any other fixing member at the level of each coupling device.

Le dispositif suivant l'invention permet de diminuer dans une mesure considérable le porte-à-faux existant entre chacun des montants 1 du cadre de lisses et l'axe du câble qui assure le déplacement de celui-ci. On peut encore réduire ce porte-à-faux pour l'amener à sa valeur minima­le, en adoptant la variante de mise en oeuvre illustrée en fig. 8, dans laquelle chaque montant 1 est constitué par une pièce à section en C contre le voile ou fond duquel est fixée la fourche 2, si bien que la tige 7 vient elle-même se loger à l'intérieur du C.The device according to the invention makes it possible to reduce to a considerable extent the overhang existing between each of the uprights 1 of the heald frame and the axis of the cable which ensures the displacement thereof. We can further reduce this overhang to bring it to its minimum value, by adopting the implementation variant illustrated in FIG. 8, in which each upright 1 is constituted by a piece with a C section against the web or bottom of which the fork 2 is fixed, so that the rod 7 itself is housed inside the C.

On comprend en outre (cf. fig. 9) qu'on peut inverser la disposition ci­dessus décrite, en fixant la fourche 2, équipée d'un talon 2c introduit dans la coulisse 8 et d'un mécanisme de mors 4-5-6, contre la tige 7 afin de coopérer avec un organe mâle 3 rendu solidaire du montant 1 du cadre de lisses. Il va de soi qu'en pareil cas, le mors 4 présente la forme d'un étrier pour permettre à l'organe mâle 3 de pénétrer dans l'ouverture 2a, lequel organe est lui-même fendu verticalement pour embrasser la tige 7, le tout comme illustré en fig. 9.We also understand (see fig. 9) that we can reverse the above described arrangement, by fixing the fork 2, fitted with a heel 2 c inserted in the slide 8 and a jaw mechanism 4-5- 6, against the rod 7 in order to cooperate with a male member 3 made integral with the upright 1 of the heald frame. There will in such cases self, the jaw 4 is in the form of a bracket to allow the male member 3 into the opening 2a, which member is itself slotted vertically to embrace the rod 7 , all as illustrated in fig. 9.

On conçoit en outre qu'en certains cas il est possible de se dispenser de la tige 7, le mécanisme de mors 4-5-6 assurant la fixation directe de l'organe femelle 2 ou de l'organe mâle 3 contre le câble de tirage ou autre élément de transmission qui assure la manoeuvre du cadre de lisses considéré.It will also be understood that in certain cases it is possible to dispense with the rod 7, the jaw mechanism 4-5-6 ensuring the direct fixing of the female member 2 or of the male member 3 against the cable. draft or other transmission element which ensures the operation of the heald frame considered.

Il convient encore d'observer que l'invention est applicable aux systè­mes de tirage du type positif dans lesquels les cadres sont commandés positivement dans les deux sens. Comme illustré en fig. 10 chaque élé­ment de transmission est ici formé, non plus par un câble, mais par une tige 9 à section polygonale dont l'extrémité inférieure est attelée par une biellette 10 à un levier de renvoi 11 qui est lui-même relié par une bielle 12 à l'autre levier de renvoi 11 et par une bielle 13 au levier oscillant de tirage correspondant de la mécanique. Chaque tige 9 est donc comparable à la tige 7 des formes de réalisation précédentes ; son orientation angulaire correcte est assurée par un guide vertical 14 qui est fixé à la structure 15 du métier par un mécanisme qui permet le recul dudit guide 14 et de la tige 9 en vue des opérations d'assemblage et de désolidarisation des organes mâle et femelle du dispositif d'ac­couplement associé à chaque montant 1 du cadre envisagé.It should also be observed that the invention is applicable to pulling systems of the positive type in which the frames are controlled positively in both directions. As illustrated in fig. 10 each transmission element is here formed, no longer by a cable, but by a rod 9 of polygonal section, the lower end of which is coupled by a link 10 to a return lever 11 which is itself connected by a link 12 to the other return lever 11 and by a connecting rod 13 to the corresponding mechanical swing lever. Each rod 9 is therefore comparable to the rod 7 of the previous embodiments; its correct angular orientation is ensured by a vertical guide 14 which is fixed to the structure 15 of the loom by a mechanism which allows the recoil of said guide 14 and of the rod 9 with a view to assembly and separation operations of the male and female organs of the coupling device associated with each upright 1 of the envisaged frame.
