Abstract
Abstract A dual spring support for particular use in supporting a vehicle or tractor cab or the like, and specifically including two co-axially disposed springs extending intermediate two spaced-apart vehicle members which are to be cushion supported relative to each other. An abutment piece is disposed between two ends of the two springs, and abutment surfaces are disposed at the other two ends of the two springs, all so that the springs are opposing in their forces and increase the force at each end of the stroke. Also a shock absorber is shown incorporated in the assembled support.

206 words
A dual spring and shock absorber support assembly, comprising two spaced-apart members which are movable toward and away from each other, a tubular connector being affixed to one of said two members and extending toward and spaced from the other of said members, an enclosure affixed to said other of said members and extending toward and spaced from said one of said members and aligned with and surrounding the extending end of said tubular connector and having two parallel and spaced-apart abutment surfaces, an abutment piece affixed to and surrounding the extending end of said tubular connector and located within said enclosure half way between said abutment surfaces and extending parallel to said abutment surfaces, and being spaced from said enclosure to be freely movable therewithin, two compression coil springs of equal strength co-axially disposed in end-to-end relation respectively between said abutment piece and said abutment surfaces and co-axial with the longitudinal axis of said tubular connector for dampening the movement of said members in both the toward and away directions, and a shock absorber extending in said tubular connector and co-axial with said two springs and being operatively connected at its respective ends with said two members for dampening shocks imposed upon said two members.
