Abstract

The Toepler pump has been modified so that it operates continuously and automatically, maintains a high vacuum, guards completely against the inclusion of air in the exhaust gas, and is easily made by the ordinary chemical experimenter. A water pump at M lowers the mercury in E, F and at the same time draws mercury into K through N. Mercury is raised in E, F by atmospheric pressure through N as soon as the surface of the mercury in U is below the lower end of the tube N. Gas from the apparatus is forced out through F, G into a collection apparatus W. The system P, Q, R, S, T is used only in starting the pump.
