Abstract
Abstract A resilient bushing assembly comprises inner and outer tubular members spaced by an elastic bushing under sufficient pressure to extrude a yieldable detent portion thereof through a radial opening in the inner member and into a detent receiving groove of a bolt located at a detent position within the inner member. The ends of the bolt extend axially beyond the bushing assembly to ride within a pair of guide slots in a corresponding pair of brackets and to seat in supported and predetermined located relationship at the slot bases. A bolt head and nut oversize with respect to the slots and spaced axially outwardly of the brackets at opposite ends of the bolt enable assembly of the bushing assembly and bolt at the detent position by movement of the bolt to its seated position through open ends of the slots whereupon the nut is tightened to draw the bolt from the detent position to clamp the bushing assembly between the brackets. Axial movement limiting flanges of the brackets overlie the bolt head and nut at the tightened position, but freely clear the flanges axially outwardly thereof during assembly when the bolt is at the detent position.
