A brush seal for first and second spaced, adjoining members which are capable of undergoing universal relative displacement, the seal comprising a plurality of flexible bristles having opposite ends, one of which is secured in a clamp causing the bristles to fan outwardly towards the other end. The second member supports a joint defining a space with a throat into which the fan of bristles enter and are resiliently squeezed at the throat. The free ends of the bristles are spaced for free movement in the joint lengthwise of the bristles to accommodate relative movement of the members towards and away from one another. Relative movement of the members longitudinally in their respective planes in taken up by sliding of the bristles within the joint while relative movement of the members transversely in their respective planes is taken up by bending of the bristles at the throat. In the case of all relative movement of the members, the bristles maintain sealing contact with the joint at the throat.

A brush seal for first and second spaced, adjoining members which are capable of undergoing universal relative displacement, said seal comprising a plurality of flexible bristles having opposite ends, means secured to the first member for securing one of the ends of the bristles to the first member in a state in which the bristles fan outwardly from said one end towards the other end and the thickness of the seal increases in a direction away from said one end, and fork means secured to the second member for embracing the other of the ends of the bristles to permit the relative universal displacement of the members while providing sealing between said members, said fork means comprising opposed spaced legs defining a space into which said other end of the bristles extends for relative free movement to accomodate said universal relative displacement of said members, said legs having free ends defining a throat at which the bristles enter said space, said legs being spaced apart by a distance less than the thickness of the fan of said plurality of bristles to apply resilient squeezing force to the bristles and provide sealing between said first and second members in their original positions and when displaced.
