Elaborate, geared apparatus for shaking cocktails

Tinkertinker sez, "I am proud to have just finished this mechanical cocktail shaker, called The Post-Imperial Shaker. It is loosely based on a turn-of-the-century machine (the 'Imperial Shaker' of course), although mine is built as a horizontal unit so that it can be mounted on a bar-top. I built this machine for The Touring Pop-up Sideshow Saloon event organized by the Peerless Prodigies of P.T. Barnum. The first Saloon event is this Sunday, May 6th, at the General Beverage Co. in San Francisco. The Post-Imperial Shaker will be there and so will I."
