IMPROVED FIRE COLLAR
A fire collar including: a mounting defining an opening adapted to receive a conduit therethrough; a layer of intumescent material supported by said mounting adjacent said opening; actuating means operatively connected to said mounting for movement from a non-operating mode proximal to said layer of intumescent material to an operating mode in which it moves in a longitudinal plane through said opening relative to the conduit to force at least a portion of said layer of intumescent material to at least partially obstruct said opening in response to the temperature reaching a predetermined level. 18 ' 19 20 Fig. 1
