These prior patents are adduced as showing a lever between a yoke and a stopper, and a lever between the bottle neek and a yoke, and as showing in each form the eccentrio action before referred to, and as showing a combination of stopper, lever, yoke, and neck wire still con- nected together and to the bottle after the bottle is unstop- pered, and capable always of moving relatively to eaeh other without disconneotion, and as showing a compound stopper composed of a rigid disk and an elastic disk.
