ABSTRACT:
A feather seal construction that interlocks a pair of feather seal elements that fit into intersecting slots. Each interlocking element is restrained axially but permits relative limited rotary motion. One of the elements is recessed with diametrically opposed slots forming an "H" shaped member and the other is apertured at one end which is then slotted, bent to allow it to fit into the diametrical slots and then joined in the original position. An extruding end adjacent one face of the interlocking element seals in an axial direction giving both radial and axial sealing characteristics.
