ABSTRACT:
An invertible timer comprises a closed transparent vessel having upper and lower chambers with a throttle therebetween, said vessel being filled with a transparent liquid in which there is a quantity of granular material, so that such material is protected from being electrostatically charged and its rate of fall is somewhat lessened. As the material fall in the liquid, a comparatively long time indication is obtained, with a small amount of material. A turn wheel in each chamber is turned by the material to show at a distance the states of time counting and termination of such counting.
