摘要:
A retainer for an adjustment device for an over-centre fastener for securing and clamping two parts (11, 12) together by applying a pulling force between said parts by means of a lever (14). The adjustment device includes an externally threaded member (17a) and an internally threaded member (19) rotatable relative to one another. The internally threaded member has a friction increasing insert (24) preventing unintentional relative rotation between the externally threaded member and the internally threaded member.

A closure assembly 10 contains positive and/or vacuum pressure within a pressure vessel 16 having a neck 12 . A circumferential locking member 22 supported on a door 20 locks the door to the neck, and is radially moveable between an open position and a closed position. A seal 26 between the neck and the door maintains fluid-tight integrity. A lever or other hand powered operator may be used for moving the locking member between the open position and the closed position. The locking member may include locking segments interconnected to form the circumferential locking member.

A closing ring (23) for a container and lid combination for securing the lid to the container includes a ring body (24) having first and second free ends to be drawn together in order to secure the lid to the container. A link clevis (32) and a lever clevis (34) are welded to the free ends. A link (33) is pivotally connected to the link clevis. A lever (35) is pivotally connected to the lever clevis. The link is connected to the lever at a third pivot connection that travels in a lever slot. The linkage arrangement is completed by the addition of a pair of closing links (36) that are pivotally connected together and connected to the lever at the lever clevis location and to the lever at the third pivot connection.

Apparatus for securing a door (1) against rotation relative to a support frame comprises a lever (4) and an articulated arm (7,8), each pivotally mounted to the door (1). The lever (4) and articulated arm (7,8) are also pivotally coupled together at coupling (6). A pair of housings (11,13) are provided on the support frame of the door (1), with a first housing (11) being configured to receive protuberant part (10) of lever (4) and a second housing (13) being configured to receive protuberant part (12) of the articulated arm (7,8), as lever (4) is pivoted around pivotal mounting (5) towards pivotal mounting (9).
摘要:
A feeder tube assembly for a feeder bowl of a glass melting furnace forehearth. The feeder tube assembly has an horizontally extending elongate support arm, and a feeder tube that is carried by the support arm at a location near an end of the support arm. The feeder tube is rotatable about its longitudinal central axis with respect to the support arm, and the support arm carries drive elements for rotating the feeder tube about its longitudinal central axis. The support arm is supported on a vertically extending servo motor actuated linear actuator, and the elevation of the support arm is adjustable by actuation of the linear actuator, a releasable brake being provided to prevent rotation of the servo motor when it is desired to prevent a change in elevation of the support arm. The position of the support arm relative to the linear actuator is independently adjustable both longitudinally of the support arm and transversely of the support arm, and the support arm is rotatable with respect to the linear actuator when it is desired to replace a feeder tube carried thereby or the feeder bowl directly below it.

A closing ring for a container and lid combination for securing the lid to the container includes a ring body (24) having first and second free ends (37, 38) to be drawn together in order to secure the lid to the container. A link clevis (32) and a lever clevis (34) are welded to the free ends. A link (33) is pivotally connected to the link clevis. A lever (35) is pivotally connected to the lever clevis. The linkage arrangement is completed by connecting the link to the lever at a third pivot connection (39a). A movable locking projection (36) is assembled to the lever clevis for engaging the lever during an opening attempt wherein the engaging prevents the opening of the ring body until the movable locking projection is moved out of its engaging position relative to the lever.
