Abstract: A coupling is provided to hold together a cone and socket joint between items of laboratory glassware. A first annular member is positioned about the cone portion of the joint and has a male threaded end. A second annular member is positioned about the socket portion of the joint and has a female threaded end which may be screwed onto the male threaded end of the first annular member. The first annular member has a seat which engages with an elastomeric sealing ring so that as the first and second annular members are tightened together the elastomeric sealing ring is compressed into the external line of junction corresponding to the outermost circumference of contact between the cone portion and the socket portion of the assembled joint. The second annular member locates indirectly behind the external strengthening lip around the mouth of the socket portion by means of an interjacent ring which has a male frustoconical surface. The second annular member has an inwardly directed flange formed with a female frustoconical surface which cooperates with the male surface of the interjacent ring whereby, in the assembled coupling, the axis of the assembled coupling is aligned with the axis of the cone and socket joint and the interjacent ring is urged radially inwards behind the socket portion of the joint.

Abstract translation: 提供联接器以将实验室玻璃器皿的物品之间的锥形和插座接头固定在一起。 第一环形构件围绕接头的锥形部分定位并具有阳螺纹端。 第二环形构件围绕接头的插座部分定位，并且具有内螺纹端部，该内螺纹端部可以旋拧到第一环形构件的阳螺纹端部上。 第一环形构件具有与弹性体密封环接合的座，使得当第一和第二环形构件被紧固在一起时，弹性体密封环被压缩到对应于锥体部分和 组装接头的插座部分。 第二环形构件通过具有雄性截头圆锥形表面的中间环间接地位于插座部分的口部周围的外部加强唇之后。 第二环形构件具有形成有内截面圆锥形表面的向内指向的凸缘，其与中间环的阳表面配合，由此在组装的联接中，组装的联接件的轴线与锥形和插座接头的轴线对齐， 相邻的环在接头的插座部分的径向向内被推压。
