GASOLINE HOUSE LIGHTING 



Gasoline gas for house lighting is manufactured in a 

 small generator by evaporating gasoline into gas and 

 mixing it with air, about 5 per cent gas and 95 per cent 

 air. We are all familiar with the little brass gasoline 

 torch heater that tinners and plumbers use to heat 

 their soldering irons. The principle is the same. 



There are three systems of using gasoline gas for 

 farmhouse lighting purposes, the hollow wire, tube sys- 

 tem, and single lamp system. 



The hollow wire system carries the liquid gasoline 

 through the circuit in a small pipe called a hollow wire. 

 Each lamp on the circuit takes a few drops of gasoline 

 as needed, converts it into gas, mixes the gas with the 

 proper amount of air and produces a fine brilliant 

 light. Each lamp has its own little generator and is 

 independent of all other lamps on the line. 



The tube system of gasoline gas lighting is similar in 

 appearance, but the tubes are larger and look more like 

 regular gas pipes. In the tube system the gas is gener- 

 ated and mixed with air before it gets into the distri- 

 bution tube, so that lamps do not require separate gen- 

 erators. 



In the separate lamp system each lamp is separate 

 and independent. Each lamp has a small supply of 

 gasoline in the base of the lamp and has a gas genera- 

 tor attached to the burner, which converts the gasoline 

 into gas, mixes it with the proper amount of air and 

 feeds it into the burner as required. Farm lanterns are 

 manufactured that work on this principle. They pro- 

 duce a brilliant light.
