  Scie circulaire pour longrines et pièces de bois analogues. 



   La présente invention a pour objet une scie circulaire pour longrines et pièces de bois analogues du type comportant une lame de scie circulaire montée sur l'arbre d'un moteur de commande et un chariot mobile de support de la pièce, pouvant se déplacer parallèlement, le long de la lame de scie. 



   Cette scie circulaire est remarquable notamment en ce que le moteur de commande est monté avec la lame de scie circulai- re sur une plaque mobile dont le trajet de mouvement est paral- lèle à celui du chariot, la plaque mobile et le chariot étant ac- couplés entre eux par un dispositif de transmission de mouvement de façon telle que le mouvement du chariot dans un sens provoque obligatoirement le mouvement de la plaque mobile dans l'autre sens. La plaque mobile et le chariot exécutent ainsi un mouvement relatif, duquel il résulte que le chariot et la pièce qu'il suppor- te ne parcourent qu'un trajet égal   à x pour   une longueur de coupe 
2 égal àx.

   Au dessin ci-joint, donné uniquement à titre d'exemple: 
Fig. 1 est une élévation latérale ; 
Fig. 2 est une vue en plan, et 
Fig. 3 est une vue de face d'une forme de réalisation de la scie circulaire suivant   l'invention.   



   Suivant la forme de réalisation représentée, le bâti de support a de la scie circulaire comporte deux bras de support al dirigés en avant et supporte deux rails de guidage b qui ser- vent à guider un chariot c de support des longrines. Les traver- ses du bâti de support a de la scie supportent deux autres rails de guidage d, dirigés parallèlement aux rails b et un peu plus bas qu'eux. Cette seconde paire de rails sert à guider une pla- que mobile e sur laquelle est monté un moteur électrique de commande f . Une lame de scie   circulaire   est fixée sur l'arbre de ce moteur, de telle sorte que le chariot.±. peut également se déplacer parallèlement devant elle. A la hauteur de la surface de support du chariot.±. est disposée une planche de support h, au-dessous de laquelle se déplace la plaque mobile sur laquelle est monté le moteur.

   Une poulie à gorge i, pouvant tourner autour d'un axe vertical, est montée sur chacune des extrémités du rail intérieur de la paire de rails de guidage b . Un câble sans fin il, passant sur ces deux poulies, est attaché par son brin posté- rieur à la plaque mobile ± et par son brin antérieur au chariot c, de telle sorte que lorsque le chariot avance dans un sens, la plaque avance obligatoirement à la même vitesse dans l'autre sens. 



  Il est facile de voir que, dans ces conditions, la longueur to- tale de la machine devient beaucoup plus courte puisque, pour une longueur de coupe,   chacun   des deux chariots n'a à parcourir que la moitié x du trajet, ainsi qu'il ressort de la Fig. 1. 



   Naturellement, l'invention n'est pas limitée au mode de réalisation décrit et représenté, qui n'a été donné   qu'à   titre d'exemple; c'est ainsi que le mécanisme de transmission de mouve-

  Circular saw for outriggers and similar pieces of wood.



   The present invention relates to a circular saw for beams and similar pieces of wood of the type comprising a circular saw blade mounted on the shaft of a control motor and a movable carriage for supporting the workpiece, able to move in parallel, along the saw blade.



   This circular saw is remarkable in particular in that the drive motor is mounted with the circular saw blade on a movable plate whose path of movement is parallel to that of the carriage, the movable plate and the carriage being ac- tivated. coupled together by a movement transmission device such that the movement of the carriage in one direction necessarily causes the movement of the movable plate in the other direction. The movable plate and the carriage thus perform a relative movement, from which it follows that the carriage and the part which it supports only travel a path equal to x for a cutting length.
2 equal to x.

   In the attached drawing, given only as an example:
Fig. 1 is a side elevation;
Fig. 2 is a plan view, and
Fig. 3 is a front view of an embodiment of the circular saw according to the invention.



   According to the embodiment shown, the support frame a of the circular saw has two support arms a1 directed forward and supports two guide rails b which serve to guide a carriage c for supporting the outriggers. The cross-sections of the support frame a of the saw support two further guide rails d, directed parallel to the rails b and a little lower than them. This second pair of rails serves to guide a movable plate e on which an electric control motor f is mounted. A circular saw blade is attached to the shaft of this motor, so that the carriage. ±. can also move parallel in front of it. At the height of the support surface of the carriage. ±. is arranged a support board h, below which moves the movable plate on which is mounted the motor.

   A grooved pulley i, rotatable about a vertical axis, is mounted on each end of the inner rail of the pair of guide rails b. An endless cable il, passing over these two pulleys, is attached by its posterior strand to the movable plate ± and by its front strand to the carriage c, so that when the carriage advances in one direction, the plate necessarily advances at the same speed in the other direction.



  It is easy to see that, under these conditions, the total length of the machine becomes much shorter since, for one cutting length, each of the two carriages only has to travel x-half of the path, as well as it emerges from FIG. 1.



   Of course, the invention is not limited to the embodiment described and shown, which has been given only by way of example; this is how the movement transmission mechanism

 <Desc / Clms Page number 3>

 By means of grooved pulleys and cable can be replaced by a chain sprocket mechanism and chain or by a rack mechanism.
