    摘要： A tapping tee comprising a body portion defining a drive socket and one or more outlet sockets in communication with the drive socket, and a saddle portion adapted to mate with and be mounted on the exterior of a main pipeline formed of a plastic material or the like. A stem member is mounted within the drive socket for rotatable and axial movement therein, such as by threaded connection. At its inner end, the stem member comprises a cylindrical cutter having a thin annular wall with a downwardly and inwardly, uniformly tapering exterior surface. When the stem member is rotated within the drive socket, such as by a suitable tool engaged with its outer end, the cutter is rotated and advanced inwardly into engagement with the plastic main pipeline. The cutter severs a circular coupon from the main pipeline and this coupon is retained within the cutter, owing to the slight deformation inwardly of the lower portion of the thin annular wall of the cutter as it is advanced through the pipeline. The tapered outer surface of the cutter creates a complementary annular tapered surface defining the opening in the pipeline. The cutter can thereafter be mated with this annular tapered surface of the pipeline to seal the opening cut therein, with the resultant advantage that the cutter can serve as a valve member for sealing the cut opening in the pipeline after the coupon is removed therefrom. A stop member is provided on the stem member above the cutter for the purpose of limiting the upward movement of the stem member and also preventing the cutter from extending too far into the main pipeline.

    摘要翻译： 包括限定驱动器插座的主体部分和与驱动插座连通的一个或多个插座的敲击开口，以及适于与由塑料材料等形成的主管道的外部配合并安装在其上的鞍形部分 。 杆构件安装在驱动器插座内，用于在其中旋转和轴向运动，例如通过螺纹连接。 在其内端，杆构件包括具有薄的环形壁的圆柱形切割器，其具有向下和向内，均匀渐缩的外表面。 当杆构件在驱动插座内旋转时，例如通过与其外端接合的适当工具，刀具被旋转并向内推进以与塑料主管道接合。 切割器从主管道切割圆形试样，并且由于当切割器通过管道前进时，切割器的薄环形壁的下部向内稍微变形，并且该试样保持在切割器内。 切割器的锥形外表面形成了在管道中限定开口的互补的环形锥形表面。 此后，切割器可以与管道的这个环形锥形表面配合，以密封其中的开口，从而得到优点，即切割器可用作阀件，用于在从中除去试样之后密封管道中的切口。 为了限制杆件的向上运动并且还防止切割器延伸得太远进入主管道，止动件设置在切割器上方的杆件上。

    摘要： Apparatus for closing off and insulating a plastic article such as a pipe section extending through a fire-resistant wall or floor to prevent the spread of fire by the progressive burning of the pipe section. The apparatus generally includes a slidably movable gate, preferably metal, which seals the walls of the plastic pipe section to interrupt it when it softens in the presence of fire and before it ignites, and baffle or screen the pipe section, thereby insuring against the spread of fire via the pipe section, such as from the hot side to the cold side of the fire-resistant wall or floor. Such apparatus may be installed on either or both sides of the wall or floor through which the plastic pipe section passes.

    摘要： A valve of the type wherein a valve member having a passageway therethrough is rotatably mounted within a valve body or housing having inlet and outlet passages. The valve body is provided with one or more raised portions on its interior surface which serve to firmly engage or bias the valve member when it is rotated to the closed position, thereby preventing leakage between the valve member and the body. In the manufacture of such a valve in accordance with the method of the present invention, the valve body is formed of a suitable plastic material and is molded about the valve member. The valve member is placed in the open position in the mold and is provided with one or more recessed portions on the outer surface thereof so that complementary raised portions are formed on the inner surface of the molded valve body which serve to firmly engage or bias the valve member when it is rotated to the closed position.
