Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
78 words
A snubber comprising a flexible tube filled with a viscous fluid, means for collapsing said tube including a roller having a fixed position laterally of said tube on one side thereof, a rotor of irregular shape on the opposite side of said tube, said tube being carried on the periphery of said rotor into engagement with said roller, said rotor being shaped to provide varying amounts of collapse of said tube as said tube moves past said roller.
Claim 2
Dependent Claim
78 words
A snubber comprising a flexible tube filled with a viscous fluid, means for collapsing said tube including a roller having a fixed position laterally of said tube on one side thereof, a rotor of irregular shape on the opposite side of said tube, said tube being carried on the periphery of said rotor into engagement with said roller, said rotor being shaped to provide varying amounts of collapse of said tube as said tube moves past said roller.
Claim 3
Dependent Claim
39 words
The device of claim 1 in which both said roller and said rotor are formed with flange means, said flange means being positioned to engage each other at the end of the desired motion to provide positive stop means.
