The axles 141 may be rotatably mounted in plates 14, Fig. 6, or may be fixed in the plates and carry the rollers, Fig. 7, not shown, or may have lugs which are fixed in the rebated grooves in one member 10 or B and have rollers on lugs in the other grooves, Fig. 9, not shown. In Fig. 4, not shown, the plates 14 are replaced by a single cylindrical member, and member 10 has a tongue engaged in an annular groove in the wing; the wing may have one or more tongues in grooves in body A.
