Abstract

Abstract A self-aligning, wear-resistant seal assembly is provided for a cable rod slidably positioned within a cable conduit. A rigid nylon ring which fits snugly around the rod is held against the end of the conduit by an elastomeric seal. The seal has an end wall which overlies the ring and has an axial bore aligned with the ring adapted for interference fit around the rod. Corresponding serrations on the conduit and seal cooperate to embracingly secure the seal to the rod.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 80 words
A self-aligning cable rod seal adapted to be mounted on a cable conduit having a cable rod slidably positioned therein comprising a relatively rigid ring bearing adapted for close contact with the rod disposed therein, and a resilient seal having an end wall axially overlying said ring bearing and axially restrained to prevent axial movement of the ring bearing, said wall having an axial bore aligned with the ring bearing and adapted for close contact with the rod disposed therein.
Claim 2
Dependent Claim 80 words
A self-aligning cable rod seal adapted to be mounted on a cable conduit having a cable rod slidably positioned therein comprising a relatively rigid ring bearing adapted for close contact with the rod disposed therein, and a resilient seal having an end wall axially overlying said ring bearing and axially restrained to prevent axial movement of the ring bearing, said wall having an axial bore aligned with the ring bearing and adapted for close contact with the rod disposed therein.
Claim 3
Dependent Claim 27 words
The apparatus of claim 1 wherein the end wall overlying the ring bearing is adapted to urge the ring bearing toward the end portion of the conduit.
Claim 4
Dependent Claim 20 words
