Abstract
An assembly and method for stiffening a flexible member according to which a stiffening member and an adapter surround the flexible member and an insert extends in an annulus between the adapter and the flexible member.
Claims16
An assembly for stiffening a flexible member, the assembly comprising:
- a stiffening member extending over a portion of the flexible member;
- an adapter secured to the stiffening member and extending over another portion of the flexible member in a spaced relation thereto to form an annulus;
- an insert disposed in the annulus;
- and
- a ring connected to an end of the stiffening member, and wherein an end of the adapter is secured to the stiffening member by a weldment extending between the adapter and the ring.
