As the temperature tem-perature rises, the mercury, expanding expand-ing up the tube pushes the rod and its saw-toothed rack before it The rack, which meshes with a series se-ries of small springs, thus turns the axis to which they are attached. On this axis there is also a large wheel, which in turn meshes with the wheel-work wheel-work of the clock spring, and consequently conse-quently winds It. When the temperature temper-ature goes down, the same rotating takes place; and between the two the clock Is always wound with no trouble to the owner. |
