Description

  

  Accessoire de potence à chasser les pierres percées.    La caractéristique de l'accessoire de po  tence à chasser les pierres percées selon la       présente    invention est que le piston de gui  dage qu'il comporte, pour la conduite de la  pierre jusqu'au trou dans lequel elle doit être  enfoncée, est pressé     élastiquement    contre une  butée réglable déterminant sa position de re  pos relativement à, la. plaque de base de l'ac  cessoire.    Avec un pareil accessoire, on pourra, sans  le séparer de la potence sur laquelle il est  monté,     adapter    la hauteur du piston de cen  trage à l'épaisseur des planches de pont, res  pectivement, de la platine à l'endroit où la  pierre doit être chassée.  



  Le dessin représente, à titre d'exemple,  une forme d'exécution de l'accessoire selon  l'invention, en coupe par un plan passant par       son    axe longitudinal.  



  L'accessoire représenté est maintenu sur le  plateau d'une potence de construction connue,  au moyen d'une plaque 10 dans laquelle est  chassé un cylindre 11, taraudé en 12 sur la  plus grande partie de sa longueur et .dans le  quel est introduit un bouchon 13, fileté, égale  ment taraudé à, son intérieur.  



  Dans ce bouchon se meut le piston de cen  trage 1.4. Celui-ci sort du bouchon 13 par le  fond 21, traverse le fond du cylindre 11 dans  un alésage 15 et dépasse ledit fond d'une hau  teur 16 qui correspond à celle de la planche  de pont 1 7 dans laquelle la pierre 18 doit être  chassée.    Le piston de centrage 14 possède une par  tie plus épaisse 19 qui est appuyée par un  ressort à boudin 20 contre le fond percé 21  du bouchon 13. Le     ressort    20 entoure une  saillie 22 qui prolonge     axialement    une vis 23,  coaxiale audit bouchon et au cylindre 11 et  qui sert à régler le ressort 20.  



  Chaque fois que le piston 24 de la potence  non représentée pousse la pierre 18, qu'on a  placée sur la pointe 25 du piston de centrage  14, dans le trou du pont 17, le piston de cen  trage suit ce mouvement et s'efface progressi  vement au fur et à mesure de la pénétration  de la pierre à l'intérieur du trou du pont. Une  fois la pierre en place, on relève le piston 24  et le pont 17 est soulevé par le ressort 20, ce  qui facilite son enlèvement.  



  Suivant la hauteur 16 du pont ou de la  platine     dans    lequel il s'agit de chasser les  pierres, il est nécessaire d'ajuster le haut du  piston de centrage pour qu'il dépasse suffi  samment l'objet en travail afin de pouvoir  mettre la pierre en place. Ce travail d'ajuste  ment se fait ici facilement après qu'on ait dé  vissé l'écrou 26 qui sert au blocage du bou  chon 13 à l'intérieur du cylindre 11. En mon  tant et     abaissant    le bouchon     13,    on modifie  la position de la pointe 25 du piston de cen  trage relativement à la surface supérieure du  cylindre pour l'ajuster au besoin du travail en  cours.



  Gallows accessory to drive out pierced stones. The characteristic of the po tence accessory for driving out drilled stones according to the present invention is that the guide piston which it comprises, for driving the stone to the hole in which it is to be inserted, is elastically pressed. against an adjustable stop determining its resting position relative to, the. accessory base plate. With such an accessory, it is possible, without separating it from the stem on which it is mounted, to adapt the height of the centering piston to the thickness of the deck planks, respectively, of the plate where the stone must be chased.



  The drawing represents, by way of example, an embodiment of the accessory according to the invention, in section through a plane passing through its longitudinal axis.



  The accessory shown is held on the plate of a bracket of known construction, by means of a plate 10 in which is driven a cylinder 11, threaded at 12 over the greater part of its length and in which is introduced. a plug 13, threaded, also threaded to its interior.



  In this stopper moves the centering piston 1.4. This leaves the stopper 13 through the bottom 21, passes through the bottom of the cylinder 11 in a bore 15 and exceeds said bottom by a height 16 which corresponds to that of the deck board 1 7 in which the stone 18 must be hunted. The centering piston 14 has a thicker part 19 which is pressed by a coil spring 20 against the pierced bottom 21 of the stopper 13. The spring 20 surrounds a projection 22 which axially extends a screw 23, coaxial with said stopper and with the cylinder. 11 and which is used to adjust the spring 20.



  Each time the piston 24 of the bracket (not shown) pushes the stone 18, which has been placed on the point 25 of the centering piston 14, into the hole in the bridge 17, the centering piston follows this movement and disappears. progressively as the stone penetrates inside the hole in the bridge. Once the stone is in place, the piston 24 is raised and the bridge 17 is lifted by the spring 20, which facilitates its removal.



  Depending on the height 16 of the bridge or of the plate in which the stones are to be driven out, it is necessary to adjust the top of the centering piston so that it protrudes sufficiently from the object being worked on in order to be able to put the stone in place. This adjustment work is done here easily after having unscrewed the nut 26 which serves to block the plug 13 inside the cylinder 11. By measuring and lowering the plug 13, the position is modified. of the tip 25 of the centering piston relative to the upper surface of the cylinder to adjust it to the needs of the work in progress.
