Abstract: A device having a pair of hollow, shell-like members pivotally coupled to each other for movement into and out of positions adjacent to each other. When the members are adjacent to each other, they form a hollow space for receiving the cork in the neck of a champagne bottle, the members having flanges for defining an opening for receiving and surrounding the neck and underlying the annular lower extremity of the cork. A pair of resilient tabs are secured to the opposite ends of the members for releasably holding the same in their closed positions. A handle on one of the members is provided to allow for an outward force to be exerted on the members away from the bottle to move the cork out of the bottle when the cork is in the closed space formed by the members. The device can be formed of metal or plastic.

Abstract: A rotatable platform assembly having upper and lower frames coupled together for rotation of the upper frame relative to the lower frame and about a first and fixed vertical axis. A large diameter ring, having its center at the first vertical axis, is mounted on the lower frame and has a cylindrical vertical outer surface and an annular horizontal track surface. The upper frame has a plurality of rollers in rolling engagement with the track and a chain sprocket mounted thereon and rotatable about a second vertical axis. A standard roller chain is trained around the ring and chain sprocket and the ring is provided with fixed chain-engaging pins and adjustable pad members engageable with the chain to take up chain slack between pins. A manually-operable, lockable and impact-releasable drive means is provided in the upper frame for rotation of the chain sprocket, so that the upper frame rotates about the first vertical axis with the rotating chain sprocket orbiting around such axis.
