ABSTRACT:
An elastomeric bumper restricts movement of large objects such as diesel engines to .+-.0.5" along the bumper's axis. The bumper includes a solid elastomeric button, an elastomeric sleeve spaced therefrom by a gap, and a rigid, tight fitting cup which surrounds the sleeve and limits the outward bulging of the elastomer. The button has an axial length which exceeds the length of the sleeve by an amount which defines a first volume of elastomer. That volume is designed to be equal to the volume of the gap. When the movement of the large object has caused the equivalent of the first volume of elastomer to flow into the gap, additional movement of the object is resisted by bulk loading of the elastomer which behaves as an incompressible fluid and resists additional motion with the full weight of the support to which the bumper is attached.
