is dropped into the water whenever additional gas isrequired. The feed mechanism F is controlled by the gasometerbell Gy which is buoyed up by the gas it contains. When thesupply of gas becomes low, the descending bell carries with itthe end of the lever F, which is attached to the feed valve;this motion raises the feed valve and allows some of the carbide 300 MECHANICS OF THE HOUSEHOLD to fall into the water. The gas that is immediately generatedpasses into the gasometer through the pipe P, and as the bell israised by the accumulating gas the valve V is closed. The gas as it enters the gasometer passes through a hollowdevice W, that looks like an inverted T, the lower edge of which istooth-shaped and extends below the surface of the water. Thegas, in passing this irregular surface, is broken up and comesthrough the water in little bubbles, in order that it may be washedclean of dust. This device also prevents the return of the gasto the generator tank during the process of charging.

The gas escapes from the bell through the pipe S to the filter D,where any dust that may have escaped the washing process isremoved by a felt filter. It finally leaves the machine by thepipe L, at which point it enters the system through which it isconveyed to the different lighting fixtures. It will be noticed that the tank (6) is divided into two compart-ments, the upper portion containing the water in which the gas-ometer floats. The lower compartment is also partly filledwith water which acts as a safety valve to prevent any escape of GASEOUS AND LIQUID FUELS 301 gas into the room in which the generator is located. The lowerend of the pipes P and S are immersed in the water at the bottomchamber of the tank, from which the gas could escape in case toomuch is generated and finally exit through the vent pipe U tothe outside air. The float A in the tank (a) is a safety device that prevents theintroduction of carbide u
