Abstract
A method of making a compressible elastomeric spring including at least one compressible elastomeric pad enclosed by a pair of metal plates includes the steps of forming plates with a center aperture and a plurality of prongs positioned about a peripheral edge thereof, forming each end of the pad with an axial projection and abutting groove, aligning the plurality of prongs with each respective projection and respective groove and applying axial force to one end of the spring to frictionally interlock the plurality of prongs with such projection and groove. The method also provides for making a multi-tiered stack of pads separated by plates in the above described manner and pre-shortening the spring prior to installation into the conventional yoke. The above described method additionally improves axial straightness and lateral stability of the multi-tiered spring assembly.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
