DEFINITION

Classification: 29/506

Securing cup or tube between axially extending concentric annuli:

(under subclass 505) Process of assembling a first tubular member with second and third relatively short tubular members wherein the second is smaller in diameter than the first and the third is larger in diameter than the first, comprising telescoping the members, i.e., assembling the members so that they share a common axis and that a plane normal to the axis passes through each of the members, so that the first member is fastened by deformation between the second and third members.

(1) Note. The "second member" and the "third member" may be concentric tubular portions of a single annulus or may be distinct members.

(2) Note. Included herein is securing a hose connector to the end of a hose and securing a bearing seal of resilient material between inner and outer metallic rings.
