ABSTRACT:
A quick release seal retainer (10,11) adapted for connecting a seal segment (13) to a base (12) has a clamp member (31) positioned within a slot (29) formed between a projection (28) of a mounting block (26) and the base (12). A pair of studs (38) slidably extending through a pair of bores (37) in the projection (28) have one end connected to the clamp member (31) and the other end connected to a bar (39). In one embodiment a cam clamp mechanism (51) is connected to the mounting block (26) for locking the bar (39) and hence the clamp member (31) at a position at which the seal segment (13) is clamped against the base (12). In another embodiment an over-center toggle link means locks the bar (39) and hence the clamp member (31) at a position at which the seal segment (13) is clamped against the base (12). Both the cam clamp mechanism (51) and the toggle link means can be easily actuated to one position to release an old seal segment and to another position to lock the new seal segment in place even when the base (12) is at an elevated operating temperature.
