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.

[ What is claimed is:] [1.] A bumper for limiting the movement of a large object when mounted adjacent a lateral extent of said large object, said bumper comprisinga) a central button of solid elastomer said button having a first axial extent;b) an elastomeric sleeve interconnected to and surrounding said button and having a second axial extent which is less than said first axial extent;c) a rigid cup enclosing said elastomeric sleeve and limiting its outward expanse;d) a backing plate received in said rigid cup to which said central button and elastomeric sleeve are bonded:e) a gap surrounding said central button and creating a space which extends for substantially all of said second axial extent and defines a first volume; said first axial extent exceeding said second axial extent by an amount which defines a second volume of elastomer, whereby if a large object traverses in a lateral direction into engagement with said bumper with sufficient force, said large object is capable of causing a volume of elastomer equal to said second volume to bulge outwardly to substantially fill said first volume whereby further movement of said large object will be resisted by bulk loading of said elastomer both in said central button and in said elastomeric sleeve due to the confinement thereof by said rigid cup.
