Description

La présente invention concerne un appareil pour la coupe en biseau d'une pièce telle qu'une planche, une moulure, etc..The present invention relates to an apparatus for bevel cutting of a part such as a board, a molding, etc.

Pour la coupe en biseau de pièces allongées, telles que les moulures destinées à former un cadre, on utilise généralement une boite à onglets qui présente une section droite en forme de U et dont les parois latérales sont percées de part en part de fentes coplanaires définissant plusieurs plans de coupe inclinés de divers angles par rapport à l'axe longitudinal de la boîte à onglets. Ces boîtes à onglets permettent généralement d'effectuer des coupes suivant des angles de 30, 45 ou 900 par rapport à l'axe longitudinal.For bevel cutting of elongated parts, such as moldings intended to form a frame, a miter box is generally used which has a U-shaped cross section and whose side walls are drilled right through coplanar slots defining several cutting planes inclined at various angles to the longitudinal axis of the miter box. These miter boxes generally allow cuts to be made at angles of 30, 45 or 90 ° relative to the longitudinal axis.

Ces boites à onglets présentent divers inconvénients. En premier lieu les valeurs des angles suivant lesquels peuvent être effectuées les coupes sont limitées et prédéterminées. Autrement dit, il n'est pas possible de couper une pièce suivant un plan de coupe faisant, avec un plan de référence, un angle autre que les angles prédéterminés par les fentes de la boite à onglets (30, 45 ou 90e). Par ailleurs les boîtes à onglets connues ont une largeur fixe et relativement réduite, ce qui limite leur emploi à la coupe de pièces relativement étroites telles que des moulures.These miter boxes have various drawbacks. First of all, the values of the angles at which the cuts can be made are limited and predetermined. In other words, it is not possible to cut a part along a cutting plane making, with a reference plane, an angle other than the angles predetermined by the slots of the miter box (30, 45 or 90 e ). Furthermore, the known miter boxes have a fixed and relatively reduced width, which limits their use for cutting relatively narrow parts such as moldings.

La présente invention concerne un appareil permettant de régler à volonté l'angle de coupe par rapport à un plan de référence et par ailleurs de couper des pièces de largeur variable.The present invention relates to an apparatus making it possible to adjust the cutting angle at will relative to a reference plane and moreover to cut parts of variable width.

A cet effet, cet appareil pour la coupe en biseau d'une pièce présentant une surface de référence par rapport à laquelle doit être incliné, de l'angle désiré, le plan de coupe, est caractérisé en ce qu'il comporte deux flasques verticaux parallèles dans lesquels sont prévues respectivement deux fentes de guidage d'une lame de scie, ces deux fentes étant parallèles et débouchant dans les chants des flasques pour définir le plan de coupe, des moyens de liaison des deux flasques verticaux parallèles pour les maintenir à distance l'un de l'autre suivant un axe transversal commun, un support monté, sur chaque flasque, orientable autour de l'axe transversal et présentant une face d'appui supérieure, les deux faces d'appui supérieures parallèles définissant un plan d'appui pour la surface de référence de la pièce à couper, et des moyens pour bloquer chaque support sur le flasque associé de manière que sa face d'appui fasse, avec la fente de guidage du flasque correspondant, un angle égal à l'angle de coupe désiré.To this end, this apparatus for bevel cutting of a part having a reference surface with respect to which the cutting plane must be inclined by the desired angle, is characterized in that it comprises two vertical flanges parallel in which are provided respectively two slots for guiding a saw blade, these two slots being parallel and opening into the edges of the flanges to define the cutting plane, means for connecting the two parallel vertical flanges to keep them at a distance from each other along a transverse axis common, a support mounted, on each flange, orientable around the transverse axis and having an upper support face, the two parallel upper support faces defining a support plane for the reference surface of the workpiece , and means for locking each support on the associated flange so that its bearing face makes, with the guide slot of the corresponding flange, an angle equal to the desired cutting angle.

Suivant une caractéristique complémentaire de l'invention les moyens de liaison entre les deux flasques verticaux parallèles sont prévus pour permettre un déplacement mutuel des deux flasques l'un en direction de l'autre, en vue d'assurer le serrage et le blocage de la pièce à couper entre les faces en regard des deux flasques. Ces moyens de liaison et de serrage sont avantageusement constitués par une tige filetée montée à rotation et bloquée en translation dans l'un des flasques et qui est vissée dans un taraudage prévu dans l'autre flasque.According to an additional characteristic of the invention, the connecting means between the two parallel vertical flanges are provided to allow mutual displacement of the two flanges one towards the other, in order to ensure the tightening and blocking of the piece to be cut between the facing faces of the two flanges. These connecting and tightening means are advantageously constituted by a threaded rod mounted for rotation and locked in translation in one of the flanges and which is screwed into a thread provided in the other flange.

L'appareil représenté sur le dessin est destiné à permettre de couper en biseau une pièce 1 qui peut être constituée par une planche, une moulure, etc. de largeur quelconque. L'appareil comporte essentiellement deux flasques verticaux parallèles 2, 3, entre lesquels s'étend la pièce à découper 1. Ces flasques 2, 3, d'épaisseur réduite, présentent une périphérie de forme quelconque délimitée par leurs chants respectifs 2a, 3a. Dans ces flasques 2, 3 sont prévues respectivement des fentes 4, 5 parallèles l'une à l'autre et qui débouchent dans les chants 2a, 3a. Ces fentes sont destinées à guider une lame de scie 6 (figure 3) pendant l'opération de coupe en biseau.The apparatus shown in the drawing is intended to make it possible to bevel a piece 1 which may consist of a board, a molding, etc. of any width. The device essentially comprises two parallel vertical flanges 2, 3, between which extends the part to be cut 1. These flanges 2, 3, of reduced thickness, have a periphery of any shape delimited by their respective edges 2a, 3a. In these flanges 2, 3 are provided respectively slots 4, 5 parallel to each other and which open into the edges 2a, 3a. These slots are intended to guide a saw blade 6 (Figure 3) during the bevel cutting operation.

La pièce à couper 1 prend appui sur deux supports 7, 8 montés à rotation sur les flasques respectifs 2, 3 autour d'un axe transversal commun xy. Les supports 7, 8 peuvent être constitués part des chapes comportant des âmes 7a, 8a parallèles aux chants 2a, 3a des flasques 2, 3 et dans lesquelles sont vissées des vis de blocage 9, 10 dont les pointes peuvent venir en contact avc les chants 2a, 3a. Les âmes 7a, 8a sont prolongées, à l'intérieur, c'est-à-dire dans l'espace compris entre les deux flasques 2, 3, par des ailes 7b, 8b de grande longueur et, à l'extérieur, par des ailes 7c, 8c beaucoup plus courtes. Ainsi chacun des supports 7, 8 en forme de chape coiffe en quelque sorte le flasque 2, 3 qui lui est associé. Les ailes internes 7b, 8b de grande longueur sont traversées par une tige filetée 11 matérialisant l'axe transversal commun xy. Ces ailes 7b, 8b présentent, sur leurs faces supérieures respectives 7e, 8e, des encoches 7d, 8d permettant l'engagement dans celles-ci du bord inférieur coupant de la lame de scie 6.The piece to be cut 1 is supported on two supports 7, 8 mounted for rotation on the respective flanges 2, 3 about a common transverse axis xy. The supports 7, 8 can be made up of yokes comprising webs 7a, 8a parallel to the edges 2a, 3a of the flanges 2, 3 and into which are screwed locking screws 9, 10 the tips of which can come into contact with the edges 2a, 3a. The cores 7a, 8a are extended, inside, that is to say in the space between the two flanges 2, 3, by wings 7b, 8b of great length and, outside, by wings 7c, 8c much shorter. Thus each of the supports 7, 8 in the form of a yoke covers in a way the flange 2, 3 which is associated with it. The internal wings 7b, 8b of great length are crossed by a threaded rod 11 materializing the common transverse axis xy. These wings 7b, 8b present try, on their respective upper faces 7e, 8e, notches 7d, 8d allowing engagement therein of the lower cutting edge of the saw blade 6.

Comme on peut le voir sur la figure 2 les ailes internes 7b, 8b des supports respectifs 7, 8 sont montées à rotation sur des moyeux internes 2b, 3b, c'est-à-dire dirigés l'un vers l'autre, des deux flasques 2, 3. La tige filetée 11 qui traverse ces moyeux 2b, 3b, est montée dans l'un des flasques, en l'occurrence dans le flasque 2, en étant bloquée en translation par rapport à celui-ci, tandis que cette tige filetée est vissée dans un trou taraudé percé de part en part dans l'autre flasque 3. Une poignée de manoeuvre 13 est prévue à l'une des extrémités de la tige filetée 11.As can be seen in Figure 2 the inner wings 7b, 8b of the respective supports 7, 8 are rotatably mounted on internal hubs 2b, 3b, that is to say directed towards each other, two flanges 2, 3. The threaded rod 11 which passes through these hubs 2b, 3b, is mounted in one of the flanges, in this case in the flange 2, being blocked in translation relative to the latter, while this threaded rod is screwed into a tapped hole drilled right through in the other flange 3. An operating handle 13 is provided at one end of the threaded rod 11.

Par ailleurs, comme on peut mieux le voir sur la figure 1, les ailes externes 7c, 8c des supports respectifs 7, 8 constituent des index mobiles en regard de graduations circulaires 14 tracées sur les faces externes des flasques 2, 3.Furthermore, as can best be seen in FIG. 1, the external wings 7c, 8c of the respective supports 7, 8 constitute movable indexes facing circular graduations 14 traced on the external faces of the flanges 2, 3.

Pour effectuer la coupe transversale en biseau d'une pièce 1 telle qu'une planche, suivant un angle a prédéterminé, on oriente tout d'abord les supports 7, 8 dans une position telle que leurs faces supérieures d'appui 7e, 8e fassent, avec les fentes de guidage 4, 5, un angle a. correspondant à l'angle désiré pour la coupe en biseau de la pièce 1. Cette orientation est obtenue en déplaçant les ailes courtes 7c, 8c formant index en regard des graduations circulaires 14 et en bloquant les supports 7, 8 au moyen des vis 9, 10 dans les positions appropriées correspondant à l'angle; a désiré. Les faces supérieures 7e, 8e des supports 7, 8 définissent ainsi un plan d'appui P (Figures 1 et 3) sensiblement horizontal pour la pièce 1 à couper. Ensuite on place la pièce 1 à couper entre les deux flasques 2, 3 et on la serre entre ces deux flasques en faisant tourner la tige filetée 11 au moyen de la poignée 13, de manière à rapprocher mutuellement les deux flasques 2, 3 jusqu'à ce que ceux-ci serrent étroitement entre eux les chants de la pièce 1, comme on peut le voir sur la figure 2.To make the bevel cross section of a part 1 such as a board, at a predetermined angle, the supports 7, 8 are first of all oriented in a position such that their upper bearing faces 7e, 8e make , with the guide slots 4, 5, an angle a. corresponding to the desired angle for the bevel cut of the part 1. This orientation is obtained by moving the short wings 7c, 8c forming an index facing the circular graduations 14 and blocking the supports 7, 8 by means of the screws 9, 10 in the appropriate positions corresponding to the angle; desired. The upper faces 7e, 8e of the supports 7, 8 thus define a support plane P (Figures 1 and 3) substantially horizontal for the part 1 to be cut. Then the piece 1 to be cut is placed between the two flanges 2, 3 and it is tightened between these two flanges by rotating the threaded rod 11 by means of the handle 13, so as to bring the two flanges 2, 3 together until so that they tighten the edges of part 1 tightly together, as can be seen in Figure 2.

Une fois la pièce 1 ainsi bloquée, il est alors facile d'engager la lame de scie dans les deux fentes de guidage 4, 5 et de scier transversalement la pièce 1, suivant le plan de coupe Pl (figures 1 et 3) qui est incliné, par rapport au plan d'appui P, de l'anglea déterminé par la position relative des fentes de guidage 4, 5 et des supports 7, 8.Once the part 1 thus blocked, it is then easy to engage the saw blade in the two guide slots 4, 5 and to cut the part 1 transversely, along the cutting plane P1 (FIGS. 1 and 3) which is inclined, relative to the support plane P, of the angle determined by the relative position of the guide slots 4, 5 and the supports 7, 8.

On voit, d'après ce qui précède, que l'appareil suivant l'invention permet de cuper la pièce 1 suivant un angle a ayant une valeur quelconque.Par ailleurs l'appareil permet de couper des pièces 1 ayant des largeurs aussi quelconques puisque les deux flasques latéraux 2, 3 peuvent être plus ou moins distants l'un de l'autre.We see from the above that the device according to the invention allows to cut the piece 1 at an angle a having any value. Furthermore the device allows to cut pieces 1 having any width as the two lateral flanges 2, 3 can be more or less distant from each other.

Les figures 4 et 5 illustrent diverses formes d'exécution des pieds pouvant être associés aux flasques 2, 3 pour leur permettre de prendre appui sur un plan approprié 15 pendant l'opération de coupe.Figures 4 and 5 illustrate various embodiments of the feet which can be associated with the flanges 2, 3 to allow them to rest on an appropriate plane 15 during the cutting operation.

Dans la forme d'exécution illustrée sur la figure 4, chacun des flasques latéraux 2, 3 est percé, dans sa partie inférieure, qui est opposée aux fentes 4, 5, d'une succession de trous 16 répartis sur un arc de cercle centré sur l'axe transversal xy et dans lesquels sont engagées les extrémités coudées 17 de pieds 18 en fil de fer ou matière similaire. Il est possible, en choisissant d'une manière appropriée les deux trous 16 dans lesquels sont engagées les extrémités coudées 17, de faire en sorte que, pendant la coupe, les supports 7, 8 et la pièce 1 à couper soient sensiblement horizontaux, comme il est illustré sur la figure 4.In the embodiment illustrated in FIG. 4, each of the lateral flanges 2, 3 is pierced, in its lower part, which is opposite to the slots 4, 5, with a succession of holes 16 distributed over a circular arc centered on the transverse axis xy and in which are engaged the bent ends 17 of feet 18 of wire or similar material. It is possible, by appropriately choosing the two holes 16 in which the bent ends 17 are engaged, to ensure that, during cutting, the supports 7, 8 and the part 1 to be cut are substantially horizontal, as it is illustrated in figure 4.

La figure 5 illustre une variante d'exécution dans laquelle chaque pied 19, constitué par une plaque verticale ayant par exemple une forme trapézoïdale, est rendu solidaire du flasque associé 2, 3 au moyen d'organes de liaison 20, tels que des billes, engagés dans deux trous 16 corres- pondans du flasque 2 ou 3.FIG. 5 illustrates an alternative embodiment in which each leg 19, constituted by a vertical plate having for example a trapezoidal shape, is made integral with the associated flange 2, 3 by means of connecting members 20, such as balls, engaged in two holes 16 corresponding to the flange 2 or 3.

La figure 6 illustre une adaptation de l'appareil suivant l'invention au cas où l'on désire conserver une largeur sensiblement constante entre les deux flasques 2, 3 pour un travail répétitif, tout en maintenant le serrage. A cet effet des cales intermédiaires rigides 21 sont disposées entre les deux flasques 2, 3 de manière à s'étendre sur la totalité de l'espace prévu entre ces deux flasques, avec additionnellement une cale éalstique 22 pour assurer le serrage. Les cales 21 peuvent avoir des largeurs différentes de manière à permettre de prérégler l'appareil pour diverses largeurs de travail. Toutes les cales rigides 21 et la cale élastique 22 sont percées d'un trou central pour le passage de la tige de serrage et de blocage 11. Ces cales présentent également de préférence, sur l'une de leurs faces frontales, des ergots 23 qui viennent s'engager dans des encoches correspondantes 24 prévues dans l'autre face frontale de la cale voisine. Les cales 21 restent ainsi légèrement emboi- tées les unes dans les autres, par suite de l'engagement des ergots 23 dans les encoches 24, lorsque l'appareil est desserré et que la cale élastique 22 est détendue. Des ergots particuliers 25 s'étendent à travers la cale élastique 22 et sont engagés dans des encoches des éléments voisins et plus particulièrement de la cale rigide 21 voisine et éventuellement dans des encoches 26 prévues dans l'un des supports 7, 8 voisins.FIG. 6 illustrates an adaptation of the apparatus according to the invention in the case where it is desired to keep a substantially constant width between the two flanges 2, 3 for repetitive work, while maintaining tightness. For this purpose rigid intermediate wedges 21 are arranged between the two flanges 2, 3 so as to extend over the entire space provided between these two flanges, with additionally an elastic wedge 22 to ensure tightening. The shims 21 may have different widths so as to allow the device to be preset for different working widths. All the rigid wedges 21 and the elastic wedge 22 are pierced with a central hole for the passage of the clamping and locking rod 11. These wedges also preferably have, on one of their front faces, lugs 23 which come to engage in corresponding notches 24 provided in the other end face of the neighboring wedge. The wedges 21 thus remain slightly nested one inside the other, as a result of the engagement of the lugs 23 in the notches 24, when the apparatus is loosened and the elastic wedge 22 is relaxed. Particular lugs 25 extend through the elastic shim 22 and are engaged in notches of the neighboring elements and more particularly of the adjacent rigid shim 21 and possibly in notches 26 provided in one of the neighboring supports 7, 8.

L'appareil de coupe en biseau représenté sur les figures 7 à 12 permet de couper des pièces de formes divere telle qu'une planche 1 (figure 11) ou une moulure d'angle 31 (figure 12), de largeur quelconque. L'appareil comporte essentiellement deux flassques verticaux parallèles 32, 33 entre lesquels s'étend et est maintenue serrée la pièce à découper. Chacun de ces flasques 32, 33 comprend une partie circulaire 32a, 33a prolongée, sur une partie de sa périphérie, par un bras 32b, 33b 's'étendant vers l'extérieur, les deux parties circulaires pouvant tourner autour d'un même axe commun xy. Par ailleurs des fentes 34, 35 de guidage d'une lame de scie, parallèles l'une à l'autre, sont ménagées dans la partie centrale circulaire 32a, 33a et dans le bras correspondant 32b, 33b des deux flasques 32, 33.The bevel cutting device shown in Figures 7 to 12 allows to cut pieces of different shapes such as a board 1 (Figure 11) or a corner molding 31 (Figure 12), of any width. The apparatus essentially comprises two parallel vertical flanges 32, 33 between which extends and is held tight the part to be cut. Each of these flanges 32, 33 comprises a circular part 32a, 33a extended, on a part of its periphery, by an arm 32b, 33b 'extending outwards, the two circular parts being able to rotate around the same axis common xy. In addition, slots 34, 35 for guiding a saw blade, parallel to one another, are provided in the circular central part 32a, 33a and in the corresponding arm 32b, 33b of the two flanges 32, 33.

Les deux flasques 32, 33 sont montés à rotation sur des supports respectifs 36, 37 constitués par deux plaques verticales parallèles, de forme rectangulaire, présentant respectivement des faces d'appui horizontales supérieures 36a, 37a pour la pièce à couper. Les deux plaques supports 36, 37 qui peuvent être fixées, à leur partie inférieure, sur une table ou un établi,présentent également, dans leurs faces externes 36b, 37b, des évidements semi-circulaires 36c, 37c dans lesquels sont logées respectivement les parties circulaires 32a, 33a des deux flasques rotatifs 32, 33.The two flanges 32, 33 are rotatably mounted on respective supports 36, 37 constituted by two parallel vertical plates, of rectangular shape, respectively having upper horizontal bearing faces 36a, 37a for the part to be cut. The two support plates 36, 37 which can be fixed, at their lower part, to a table or a workbench, also have, in their external faces 36b, 37b, semi-circular recesses 36c, 37c in which the parts are housed respectively. circular 32a, 33a of the two rotary flanges 32, 33.

Les deux plaques supports 36, 37 portant les deux flasques rotatifs associés 32, 33 sont reliées l'une à l'autre par l'intermédiaire de la tige filetée 11 matérialisant l'axe transversal commun xy autour duquel tournent les deux flasques 32, 33. Cette tige filetée 11 est montée à rotation dans l'une des plaques supports, par exemple la plaque 37, en étant bloquée en translation par rapport à celle-ci, tandis que cette tige filetée est vissée dans un trou taraudé percé de part en part dans l'autre plaque support 36. Les deux flasques 32, 33 sont montés librement à rotation autour de l'axe commun xy, sur leurs plaques supports respectives 36, 37, et ils peuvent être bloqués sur ces plaques supports dans toute position angulaire désirée par rapport à ces plaques, position dans laquelle les fentes de guidage 34, 35 font, avec les faces d'appui supérieures 36a, 37 des plaques supports 36, 37 un angle suivant lequel doit s'effectuer la coupe en biseau.The two support plates 36, 37 carrying the two associated rotary flanges 32, 33 are connected to each other by means of the threaded rod 11 materializing the common transverse axis xy around which the two flanges 32, 33 rotate. This threaded rod 11 is rotatably mounted in one of the support plates, for example the plate 37, being locked in translation relative to the latter, while this threaded rod is screwed into a tapped hole drilled right through. share in the other support plate 36. The two flanges 32, 33 are mounted to rotate freely around the common axis xy, on their respective support plates 36, 37, and they can be locked on these support plates in any angular position desired with respect to these plates, position in which the guide slots 34, 35 make, with the upper bearing faces 36a, 37 of the support plates 36, 37 an angle at which the bevel cut must be made.

Pour permettre facilement le repérage de l'angle de coupe, chacun des flasques 32, 33 présente, sur sa face externe et le long de sa périphérie, une échelle graduée circulaire 38 défilant devant un index 39 solidaire d'un bouton de blocage 41 porté par la plaque support correspondante. Ce bouton 41 permet de bloquer le flasque correspondant dans la position angulaire désirée, lorsque l'index 39 se trouve être placé en regard de la graduation désirée de l'échelle 38 portée par le flasque. Dans les faces supérieures horizontales d'appui 36a, 37a des plaques supports 36, 37 sont prévues des découpes 42 qui se trouvent toujours alignées, si on regarde dans une direction parallèle à l'axe commun de rotation xy, avec les parties extrêmes des fentes 34, 35 de guidage de la lame de scie. Les deux découpes 42 sont situées à proximité immédiate de la tige filetée 41 matérialisant l'axe de rotation xy.To allow easy identification of the cutting angle, each of the flanges 32, 33 has, on its outer face and along its periphery, a circular graduated scale 38 scrolling past an index 39 secured to a locking button 41 carried by the corresponding support plate. This button 41 makes it possible to block the corresponding flange in the desired angular position, when the index 39 is found to be placed opposite the desired graduation of the scale 38 carried by the flange. In the horizontal upper support faces 36a, 37a of the support plates 36, 37 are provided cutouts 42 which are always located aligned, if one looks in a direction parallel to the common axis of rotation xy, with the end portions of the slots 34, 35 for guiding the saw blade. The two cutouts 42 are located in the immediate vicinity of the threaded rod 41 materializing the axis of rotation xy.

Les plaques supports 36, 37 présentent, à la partie supérieure de leurs faces internes 36d, 37d, des appuis respectifs 43, 44 dont les surfaces supérieures sont à fleur avec les faces d'appui horizontales 36a, 37a et qui sont constituées par des languettes horizontales s'étendant transversalement, c'est-à-dire parallèlement à l'axe xy. Les languettes d'appui 43 de la plaque support 36 s'étendent en direction de l'autre plaque support 37 et inversement les languettes d'appui 44 de cette plaque support 37 s'étendent en direction de l'autre plaque support 36. Dans l'axe de ces languettes 43, 44 sont prévues, dans la plaque support opposée, des fentes dans lesquelles ces languettes d'appui 43, 44 peuvent s'engager, à savoir des fentes 45 ménagées dans la partie supérieure de la face interne 36d de la plaque support 36 et qui débouchent dans la surface d'appui supérieure 36a, et des fentes 46 ménagées dans la partie supérieure de la face interne 37d de la plaque support 37 et qui débouche dans la suface d'appui supérieure 37a.The support plates 36, 37 have, at the upper part of their internal faces 36d, 37d, respective supports 43, 44 whose upper surfaces are flush with the horizontal bearing faces 36a, 37a and which are constituted by tongues horizontal extending transversely, that is to say parallel to the xy axis. The support tabs 43 of the support plate 36 extend in the direction of the other support plate 37 and conversely the support tabs 44 of this support plate 37 extend in the direction of the other support plate 36. In the axis of these tongues 43, 44 are provided, in the opposite support plate, slots in which these support tongues 43, 44 can engage, namely slots 45 formed in the upper part of the internal face 36d of the support plate 36 and which open into the upper support surface 36a, and slots 46 formed in the upper part of the internal face 37d of the support plate 37 and which open into the upper support surface 37a.

En regard des fentes 45, 46 les deux flasques 32, 33 présentent, sur leurs faces internes en regard, des rainures circulaires 47 qui sont centrées sur l'axe de rotation xy des deux flasques.Opposite the slots 45, 46 the two flanges 32, 33 have, on their facing internal faces, circular grooves 47 which are centered on the axis of rotation xy of the two flanges.

On voit, d'après la description qui précéde, qu'il est possible de serrer une pièce à découper telle qu'une planche 1, entre les deux flasques 32, 33, tant que ces pièces ont une largeur supérieure à 2x, x étant la largeur des surfaces horizontales d'appui supérieures 36a, 37a délimitées par les évidements 36c, 37c d'une part et les faces internes 36d, 37d d'autre part. Les languettes 43, 44 qui s'étendent transversalement, contribuent à l'appui des pièces devant être découpées et si ces pièces ont une faible largeur, elles s'engagent dans les fentes 45, 46 et éventuellement dans les rainures 47 des flasques 32, 33.We see, from the above description, that it is possible to clamp a piece to be cut such as a board 1, between the two flanges 32, 33, as long as these pieces have a width greater than 2x, x being the width of the upper horizontal support surfaces 36a, 37a delimited by the recesses 36c, 37c on the one hand and the internal faces 36d, 37d on the other hand. The tongues 43, 44 which extend transversely, contribute to the support of the parts to be cut and if these parts have a small width, they engage in the slots 45, 46 and possibly in the grooves 47 of the flanges 32, 33.

Si la pièce à découper a une largeur inférieure à la valeur 2x précitée, il est alors nécessaire de faire appel à une cale intermédiaire 48 telle que représenté sur la figure 9. La cale 48 comporte une âme verticale 49 de faible épaisseur, destinée à venir se loger entre les deux plaques supports 36, 37 et qui se raccorde, à sa partie supérieure, à une embase horizontale 51 de section carrée ou rectangulaire laquelle est à son tour prolongée vers le haut par un bras vertical 52. La partie supérieure de l'âme 49 et l'embase 51 présentent une découpe 53 de forme appropriée permettant d'engager la cale intermédiaire 48 sur la tige filetée 11, lorsque cette cale est utilisée. Par ailleurs des fentes 54 sont prévues dans la partie supérieure de l'âme 49 juste en dessous de l'embase 51, pour permettre l'engagement, dans ces fentes, des languettes d'appui 43, 44 portées par les plaques supports 36, 37. Les positions des fentes 54 et leur nombrecorrespondent respectivement à celles des languettes d'appui 43, 44. Le bras 52 présente par ailleurs une lumière verticale 55 dans laquelle peut coulisser un boulon 56 assurant le blocage d'une butée 57 constituée par une petite équerre. La lumière 56 présente deux parties de largeur différente à savoir une partie 56a de largeur relativement grande dans laquelle coulisse la tête du boulon 56 et une partie plus étroite 56b dans laquelle coulisse la tige de ce boulon.If the piece to be cut has a width less than the aforementioned 2x value, it is then necessary to use an intermediate shim 48 as shown in FIG. 9. The shim 48 has a vertical core 49 of small thickness, intended to come be housed between the two support plates 36, 37 and which is connected, at its upper part, to a horizontal base 51 of square or rectangular section which is in turn extended upwards by a vertical arm 52. The upper part of the 'core 49 and the base 51 have a cutout 53 of suitable shape for engaging the intermediate wedge 48 on the threaded rod 11, when this wedge is used. In addition, slots 54 are provided in the upper part of the core 49 just below the base 51, to allow engagement, in these slots, of the support tabs 43, 44 carried by the support plates 36, 37. The positions of the slots 54 and their number correspond respectively to those of the support tabs 43, 44. The arm 52 also has a vertical opening 55 in which a bolt 56 can slide to ensure the locking of a stop 57 constituted by a small square. The light 56 has two parts of different width, namely a part 56a of relatively large width in which the head of the bolt 56 slides and a narrower part 56b in which the rod of this bolt slides.

La figure 10 illustre l'utilisation de la cale intermédiaire 48 pour la coupe en biseau d'une barre 58 de largeur a inférieure à 2x. Dans ce cas la cale intermédiaire 48 est montée sur l'une des plaques supports, par exemple la plaque support 37. La cale intermédiaire 48 vient se plaquer contre la face interne 37d de cette plaque support 37, les languettes d'appui 44 de cette plaque support s'engageant alors dans les fentes 54 de l'âme 49 de la cale intermédiaire. La cale intermédiaire peut être maintenue par un téton 58 solidaire de l'âme 49 et perpendiculaire à celle-ci, ce téton venant s'engager à force dans un trou 59 percé dans la partie inférieure de la plaque support 37, parallèlement à l'axe xy.L'embase 51 de cette cale vient prendre appui sur la surface horizontale supérieure 37a de la plaque support 37 et le serrage de la pièce 58 s'effectue alors entre le flasque opposé 32 et la face verticale en regard de l'embase 51.FIG. 10 illustrates the use of the intermediate shim 48 for the bevel cut of a bar 58 of width a less than 2x. In this case the intermediate shim 48 is mounted on one of the support plates, for example the support plate 37. The intermediate shim 48 comes to be pressed against the internal face 37d of this support plate 37, the support tabs 44 of this support plate then engaging in the slots 54 of the core 49 of the intermediate wedge. The intermediate wedge can be held by a stud 58 integral with the core 49 and perpendicular thereto, this stud coming to forcely engage in a hole 59 drilled in the lower part of the support plate 37, parallel to the xy axis. The base 51 of this wedge comes to bear on the upper horizontal surface 37a of the support plate 37 and the clamping of the part 58 is then carried out between the opposite flange 32 and the vertical face opposite the base 51.

La figure 12 illustre l'utilisation de la cale intermédiaire 48 pour la coupe en biseau d'une moulure d'angle 31. Dans ce cas cette moulure 31 est maintenue inclinée entre la surface d'appui supérieure 37a et les languettes d'appui 44 de la plaque support 37 et la butée 57 de la cale intermédiaire 48 qui est alors plaquée contre la face interne 36d de la plaque support opposée 36. La butée supérieure 57 est bloquée dans la position appropriée correspondant aux dimensions et à la forme de la moulure d'angle 1 devant être coupée.FIG. 12 illustrates the use of the intermediate shim 48 for the bevel cut of an angle molding 31. In this case this molding 31 is kept inclined between the upper bearing surface 37a and the support tongues 44 of the support plate 37 and the stop 57 of the intermediate shim 48 which is then pressed against the internal face 36d of the opposite support plate 36. The upper stop 57 is locked in the appropriate position corresponding to the dimensions and to the shape of the molding angle 1 to be cut.
