    PERFECTIONNEMENTS   AUX   GARNITURES     POUR¯BOITES   A   PRESSES-ETOUPES   
Pour rendre étanches les boîtes à presses-étoupes, on les a pourvues de garnitures en graphites et.charbons avec des adjonctions d'huiles ou de graisses comme liants et comme moyens de graissage.

   Afin d'augmenter l'étanchéité qui était entravée par certains inconvénients des compositions tels que      durcissement et carbonisation des matières graisseuses, on a ensuite supprimé l'adjonction de tout métal et de tout' liant, organique ou anorganique, particulièrement de toute matière graisseuse, et on a composé des garnitures de charbon amorphe, comme par exemple du graphite, et .d'amiante pulvérisée ou en fibres, auxquelles on a avantageusement ajouté, suivant l'emple de la suie, de la poudre de talc ou du verre pulvérisé. Ces compositions, bien que correspondant déjà mieux aux qualités exigées, ne donnaient néanmoins pas entière satisfaction,leur élasticité et leur résistance aux hautes pressions étant toujours limitées. 



   La présente invention répond à tous les besoins par des perfectionnements aux garnitures pour boîtes à presses-étoupes caractérisés par le fait qu'outre le charbon amorphe, comme par exemple du graphite, et l'amiante de préférence en fibres, les garnitures comportent de la laine de verre. En outre, des sili- cates et/ou des sulfates y sont ajoutés. On emploie avantageu- sement de la laine de verre très fine ainsi que des silicates 

 <Desc/Clms Page number 2> 

 et sulfates pulvérisés.

   Les garnitures pour boîtes à presses- étoupes sont de plus confectionnées et préparées en différentes formes comme, par exemple,en tresses, cordes, plaques ou toute autre forme désirée, et particulièrement comme bagues d'étan- chéité permettant une application sans bague de fond et/ou   bagus     couverte   généralement faite en amiante et/ou métal. 



   Des garnitures pour boîtes à presses-étoupes suivant la présente invention possèdent et conservent une élasticité beau- coup plus grande que celles connues jusqu'ici, grâce à l'ad- jonction de la laine de verre et à l'élasticité qui est propre à cette dernière. Les silicates et sulfates qui, en état pulvé- risé, se mélangent parfaitement au charbon amorphe et à l'ami- ante, maintiennent les surfaces des parties mobiles et à rendre étanches (par exemple arbre) polies et lisses et en conséquence à l'abri de toute corrésion. En outre, par l'adjonction de sili= cates et sulfates finement pulvérisés,toutes les fissures des garnitures sont efficacement bouchées de sorte que ces garni- tures résistent aux pressions les plus élevées.

    IMPROVEMENTS TO THE PIPE GASKETS WITH PACKING PRESSES
To make the cable gland boxes watertight, they were provided with graphite and charcoal gaskets with additions of oils or greases as binders and as lubricants.

   In order to increase the seal which was hampered by certain drawbacks of the compositions such as hardening and carbonization of fatty materials, the addition of any metal and any binder, organic or inorganic, particularly any fatty material, was then eliminated, and fillings of amorphous carbon, such as for example graphite, and pulverized or fiber asbestos, to which soot, talcum powder or pulverized glass have advantageously been added, according to the example. These compositions, although already corresponding better to the required qualities, were nevertheless not entirely satisfactory, their elasticity and their resistance to high pressures still being limited.



   The present invention meets all the needs by improving the linings for cable gland boxes characterized by the fact that in addition to amorphous carbon, such as for example graphite, and asbestos, preferably in fibers, the linings include glass wool. In addition, silicates and / or sulfates are added thereto. Very fine glass wool as well as silicates are advantageously used.

 and pulverized sulphates.

   The gaskets for cable glands are furthermore made up and prepared in different shapes such as, for example, in braids, ropes, plates or any other desired shape, and particularly as sealing rings allowing application without a bottom ring. and / or covered ring generally made of asbestos and / or metal.



   Packings for cable glands according to the present invention possess and maintain a much greater elasticity than those known heretofore, thanks to the addition of glass wool and to the elasticity which is characteristic of the invention. the latter. The silicates and sulphates which, in a pulverized state, mix perfectly with the amorphous carbon and the asbestos, keep the surfaces of the moving parts and to be sealed (for example shaft) polished and smooth and consequently to the safe from any corrosion. In addition, by the addition of finely powdered silicates and sulphates, all cracks in the gaskets are effectively sealed so that these gaskets withstand the highest pressures.
