    • A device in which a conic-shaped mantle and a cup-shaped bottom portion are assembled on a conic-shaped pin by a mantle seam sealing operation, and a placement of the bottom portion within the narrower end of the mantle, projecting beyond the pin, in flanged interlocking relationship. In the sealing operation a movable member is associated with the pin to be extensible along the seam line of the mantle which is received over the pin and has a portion extending beyond the pin, so as to provide an abutment surface at this portion against which a pressing member urges the mantle at the seam line. After this movable member is retracted another member places the bottom portion in position in the mantle and a still further member urges the bottom portion and mantle into interlocking relationship.
    • 一种装置,其中锥形地幔和杯形底部通过地幔缝密封操作组装在锥形销上,并且将底部部分放置在地幔的较窄端部内,突出超过销 在法兰联锁关系。 在密封操作中,可移动构件与销相关联,以沿着套筒的接缝线延伸,所述接缝线被接收在销上并具有延伸超过销的部分,以便在该部分处提供抵靠表面, 按压构件在接缝线上推动地幔。 在该可移动部件被缩回之后,另一个部件将底部部分放置在套筒中的适当位置,并且另外的部件促使底部部分和套管互锁。
