Application No. 09/407,053
BACKGROUND
The appellant's invention relates generally to springs and is more specifically
directed to devices that dampen lateral rolling motions that occur during the movement
of railroad cars (specification, p. 1). A copy of the dependent claims under appeal is set
forth in the appendix to the appellant's brief. Claims 1 and 15, the independent claims
under appeal, read as follows:
1. A bearing pad assembly comprising:
a first housing having an exterior surface and defining a bore extending at
least part-way through said first housing;
a first load bearing member coupled to said first housing, and defining an
outwardly facing first abutment surface;
a second housing defining a bore of a shape similar to said exterior
surface of said first housing and adapted to slideably receive said first housing
therein;
a second load bearing member coupled to said second housing and
defining an outwardly facing second abutment surface opposite to said first
abutment surface;
at least one slip lining positioned between said first housing exterior
surface and a bore wall defining said second housing bore; and
at least one compression spring positioned within said first housing bore,
said compression spring comprising a solid resilient material having a torus
shape.
15. A bearing pad assembly comprising:
a first housing having a bore extending through said first housing;
a first load bearing member coupled to said first housing and defining an
abutment surface opposite to said first housing;
a second housing having a bore extending through said second housing
adapted to telescopically receive said first housing;
a second load bearing member coupled to said second housing and
defining an abutment surface opposite to said second housing; and
at least one compression spring in the shape of a torus positioned within
said first housing bore.
