For sale is an antique astronomical planisphere antique astronomical device based on an antique clock mechanism. The device is very unusual and likely rare and unique. The device is contained in a nicely constructed oak box which measures 18 1/2" X 18 1/2" X 4 1/2". The device operates automatically a 15 1/2" diameter planisphere made by henry Whitall, a New York and Philadelphia publisher. His planispheres were sold from 1856 until later in the 19th Century.
The Seth Thomas clock movement drives the planisphere by a set of teeth mounted on a frame beneath the planisphere. There are three rods which run from the device to the outside of the case. One is for winding the mechanism, one is for stopping the balance, one is for advancing the planisphere manually.
The device is in working order. The movement runds and winds and the planisphere function seems to work (I am no astronomer). It is ticking away as I write this.
Ask me any questions you might have, and I will be happy to try to answer them. The device consists of the main box with movement attached, the planisphere, the planisphere surround which is nicely hand lettered, and a frame with glass.
