摘要： A clamping band for clamping a resilient gasket against an opening within a wall to provide a fluid-tight seal therebetween. The clamping band is generally circular-shaped and has an elongated slot extending inwardly from one free end of the clamping band and cooperates with an elongated projection of reduced cross section as compared with the nominal cross section of the clamping band and which is provided at the opposite end of the band. The projection is inserted into the slot, the clamping band is placed against the gasket arranged within the aforesaid opening and the gasket is expanded a predetermined amount by an hydraulic expander to exert the desired clamping pressure upon the resilient gasket. One surface of the projection is provided with a series of teeth. An opening communicating with said slot receives a wedge fitted into said opening and having several teeth along one surface thereof, which teeth conform to the teeth of said projection. Insertion of the wedge inter-engages the teeth of the projection and the wedge locking the clamping band in the desired position with the requisite amount of the clamping pressure. The wedge is preferably tapped into the locking position and is also removable for whatever purpose and is reusable. The teeth may be replaced with openings in opposite sidewalls of the slot and in the projection. The insert is replaced by drive pins inserted into cooperating openings in the projection and sidewalls.

摘要： Method and apparatus for providing inserts, such as lift inserts and step inserts, in cast members. The inserts have breakaway tabs mounted in receiving slots in either a reusable holder or disk-shaped member. The assembled insert and holder are inserted through a collar on the outer jacket of a mold assembly and a locking pin passes through cooperating openings in the holder and collar to retain the lift insert/holder in place during the casting operation. The disk-shaped member is fixed to a jacket of the mold assembly. The breakaway tabs break away from the insert when the cast member is separated from the mold assembly, the breakaway tabs being discarded and the holder (disk-shaped member) being reusable many times for subsequent casting operations. The slots, in one embodiment, have a locking shoulder to lock the tabs in their slots. In another embodiment, a cam surface on the tabs lock the tabs in the slots. In another embodiment, one slot and one tab differ in radial or circumferential length from the other tabs and slots to permit alignment between the slots and tabs in only one position to assure that the tabs are properly mounted in the holder.
