  Class Definition for Class 267 - SPRING DEVICES
Spring device including a compartment or material adapted to contain a fluid to be applied to relatively moving portions of the device to reduce friction therebetween.
Device in which one of the diverse springs is a metallic member and another of the springs comprises a fluid containing compartment having a restricted or valved orifice to regulate the flow of fluid into or out of the compartment, and the flow of fluid through the orifice dampens the movement of the metallic spring.
Device wherein the panel is composed of a series of spiral springs, arranged with the axes of the spirals parallel to each other and aligned in the direction the load is received, and in which the spiral springs are of the type which receive the load in compression.

The static equilibrium between the springs 11,12 is thereby upset and the first spring 11 is also expanded, thus causing the supporting rod 8 and the plate 9 to be moved forward from the neutral position to a first position P 1, downstream relative to the neutral position N2 and the vessel's forward direction.
The first compression spring 11 is thereby compressed, with the result that the plate 9 is moved backwards, past the neutral position N2 to a second position P2, upstream relative to the neutral position N2.

 spring locking device
Stan - springs have a known restoring force and the force a spring exerts is proportional to how much its compressed/expanded.
As you apply torque the drive is attached to the ramp that applies the force (from the torque) to the spring.
At some point the force applied by the ramp is greater than the spring so the ramp is allowed to move and when it does it releases from the drive so the drive can freewheel.

The lower court granted summary judgment in favor of Traffix holding that MDI could not establish secondary meaning in its alleged trade dress because the dual spring design was functional and there was an absence of source/good recognition by consumers.
In earlier litigation, MDI argued that the springs in a very different-looking dual-spring design device fell within the claims of MDI’s patents under the doctrine of equivalents.
Traffix’s dual-spring device would have been covered by the claims of MDI’s expired patents in its earlier litigation, thus providing further evidence of functionality.
