Abstract

A cushioning device for soft, reboundless braking of an intermittently operating, movable part of a mechanical mechanism of a photographic camera or like precision apparatus in which a double lever is journaled adjacent its center, one arm of the double lever is actuated to rotate the double lever about its journal by the movable part, a return spring is attached to the other arm of the double lever and is tensioned by the rotation of the double lever by the movable part, a brake link is journaled at a point offset from the first journaling point, extends toward the first journaling point and has a zigzag groove formed therein and a pin on the other arm of the double lever engages the zigzag groove and causes the brake link to oscillate with an amplitude which increases as the pin approaches the first journaling point when the double lever is rotated by the movable part.
