  BREVET D'INVENTION

  
Les poches de coulée pour les métaux en fusion sont articulées sur un harnais de support de manière à pouvoir pivoter pour verser dans des moule* le métal fondu qu'elles contiennent. En raison des variations 'brutales de températures auxquelles sons exposés ces dispositifs, ils subissent des déformations pouvant donner lieu à des grippages rendant l'opération de 'basculement pénible et parfois dangereuses La présente invention a pour but de supprimer  oes inconvénients* 

  
Conformément à l'invention, la liaison entre la poche proprement dite et ses pivote ou tourillons est réalisée par l'intermédiaire d'organes présentant entre eux un jeu approprié et adaptés pour permettre des mouvements de la poohe par rapport aux tourillons,

  
 <EMI ID=1.1> 

  
entre eux, à la manière des axes d'un joint de cardan.

  
D'une part, le jeu freine la transmission de la chaleur entre la poohe et les tourillons et, d'autre part, les déplacements relatifs autorisés entre la poohe et les tourillons absorbent les déformation* de la poohe, sans que oellea-oi soient transmise. aux tourillon., dont le pivotement dans le support de la poohe reste facile*

  
La description qui va suivre, en regard des dessins annexés, donnée à titre d'exemple non limitatif, fera bien comprendre les différentes particularités de l'invention et l'art de les réaliser, toute disposition, ressortant tant du texte que des figures, rentrant bien entendu, dans le cadre de la présente invention.

  
La figure 1 est une vue en élévation aveo ooupe partielle d'une poohe de coulée et de son support dans un premier mode de réalisation de l'invention. La figure 2 est une coupe partielle de la <EMI ID=2.1> 

  
Sur les figures 1 et 2 on voit en 1 la poche de coulée et en 2 le harnais auquel elle est suspendue et par rapport auquel elle doit pouvoir pivoter autour de l'axe A-A pour le déversement du métal fondu. La poohe est munie à cet effet de deux tourillons 3 qui peuvent tourner dans des paliers 4 portés par des bras verticaux 5 du harnais. Quand on a libéré le verrou 6  <EMI ID=3.1> 

  
de la poche est commande au moyen d'un volant 7 qui  agit sur l'un des tourillons par l'intermédiaire d'un réducteur contenu dans une boite 8.

  
. Les tourillons 3 s'engagent par une tête 13 à l'intérieur de deux ferrures 14 qui sont fixées sur .la poche. Chacune des têtes 13 présente deux surfaces <EMI ID=4.1> 

  
d'un joint de cardan et à permettre de petites rotations

  
 <EMI ID=5.1> 

  
du dessin, les deux surfaces arrondies sont deux portions de cylindre. Une portion 15 est à génératrices verticales,

  
 <EMI ID=6.1> 

  
culaires au plan de la figure 1. Pour chaque tourillon une broohe 17 traversant la tête 13 et des boutonnières 
18 de la ferrure 14 correspondante, assure le maintien en plaoe des tourillons tout en permettant les mouvements .relatifs entre la poohe et les tourillons. Le montage est <EMI ID=7.1> 

  
20 entre chaque tête 13 et la ferrure 14 correspondante*

  
On oomprend que oe dispositif permet les déformations de la poche, sans que les tourillons en soient affectés.

  
Tous les efforts provenant des déformations de la poche lors de son échauffement quand on la remplit de métal liquide ou lors de son refroidissement sont

  
 <EMI ID=8.1> 

  
que forment les surfaces arrondies 15 et 16 et la broche
17 montée aveo jeu dans les boutonnières 18. Les tourillons restent donc parfaitement alignés et le pivotement de la poche est toujours facile.

  PATENT

  
Pouring ladles for molten metals are hinged to a support harness so that they can pivot to pour the molten metal they contain into molds. Due to the sudden variations in temperature to which these devices are exposed, they undergo deformations which can give rise to seizures making the tipping operation painful and sometimes dangerous. The object of the present invention is to eliminate these drawbacks *

  
According to the invention, the connection between the pocket proper and its pivots or journals is produced by means of members having between them a suitable clearance and adapted to allow movements of the pocket relative to the journals,

  
 <EMI ID = 1.1>

  
between them, like the axes of a universal joint.

  
On the one hand, the play slows down the transmission of heat between the poohe and the journals and, on the other hand, the relative displacements authorized between the poohe and the journals absorb the deformation * of the poohe, without oellea-oi being transmitted. to the trunnions, the pivoting of which in the support of the poohe remains easy *

  
The description which will follow, with reference to the appended drawings, given by way of non-limiting example, will give a clear understanding of the various particularities of the invention and the art of making them, any arrangement, apparent both from the text and from the figures, falling within the scope of the present invention of course.

  
Figure 1 is a partial view in elevation aveo ooupe of a casting poohe and its support in a first embodiment of the invention. Figure 2 is a partial section of the <EMI ID = 2.1>

  
In Figures 1 and 2 we see at 1 the casting ladle and at 2 the harness from which it is suspended and with respect to which it must be able to pivot about the axis A-A for the discharge of the molten metal. The poohe is provided for this purpose with two journals 3 which can rotate in bearings 4 carried by vertical arms 5 of the harness. When lock 6 has been released <EMI ID = 3.1>

  
of the pocket is controlled by means of a handwheel 7 which acts on one of the journals via a reducer contained in a box 8.

  
. The journals 3 engage via a head 13 inside two fittings 14 which are fixed to the pocket. Each of the heads 13 has two surfaces <EMI ID = 4.1>

  
a universal joint and allow small rotations

  
 <EMI ID = 5.1>

  
in the drawing, the two rounded surfaces are two portions of a cylinder. A portion 15 has vertical generators,

  
 <EMI ID = 6.1>

  
culars to the plane of figure 1. For each journal a pin 17 passing through the head 13 and buttonholes
18 of the corresponding fitting 14, maintains the pins in plaoe while allowing the relative movements between the poohe and the pins. The mount is <EMI ID = 7.1>

  
20 between each head 13 and the corresponding fitting 14 *

  
It is understood that this device allows the deformation of the pocket, without the pins being affected.

  
All the forces resulting from the deformations of the ladle during its heating when it is filled with liquid metal or during its cooling are

  
 <EMI ID = 8.1>

  
formed by the rounded surfaces 15 and 16 and the spindle
17 ascent with play in the buttonholes 18. The pins therefore remain perfectly aligned and the pocket pivoting is always easy.

  
 <EMI ID = 9.1>

  
usual belt connecting the journals to the pocket being removed.

  
Of course other embodiments

  
 <EMI ID = 10.1>
