Abstract
An improved braked or snubbed joint assembly for use for supporting a grapple, clam shell or like device, is disclosed. The present braked or snubbed joint assembly includes a first member including an element defining an elongate cylindrical bore therethrough having a central axis, and first and second outwardly tapered or conical convex axial end faces. A second member having first and second arms defining a space therebetween receives the first member, and an axial pin rotatably joins the first member and the second member. The second member includes an element located in the space which has a correspondingly tapered or conical concave axial end face positioned in spaced opposed relation to the first outwardly tapered or conical convex axial end face and the second arm includes an element located in the space which has a correspondingly tapered or conical concave axial end face positioned in spaced opposed relation to the second outwardly tapered or conical convex axial end face. Frictional brake elements are disposed between the opposed axial end faces for frictionally resisting or braking relative rotation of the first and second members.
