MANU unsigned prior to 8th April 1726 London, England. DES HAUKSBEE,Francis,Junior. 1714 London, England. DES WHISTON,William. 1714 London, England. This atronomical clock movement was originally called simply 'a train of wheel work' by itsinventors Francis Hauksbee junior and William Whiston. It is constructed using early metalworking techniques which were based on carpentry. The multiplying ratio of the gear train is one-hundred to one i.e. for each turn of the handle the output drive axle rotates one-hundred times as indicated on the revolution counter scale. The machine can also be operated by lead weights attached to the wheels. In the past someone has attempted to do so but have mistakenly used two wieghts of approximately the same value made of lead wire! | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
