Click to enlarge

Structure of mechanism
Function The barometer is housed in a rectangular box, one of whose sides is made of glass. Inside there is a brass cylinder to which a sheet of squared paper is attached. To the side there is a row of aneroid capsules (invented in 1843 by Lucien Vidie). These cylinders are connected to a large needle which traces variations in atmospheric pressure on the squared paper. One week’s data can be recorded before the paper has to be changed.
