NEW BATTERY JAR COVER. 



tery jar cover, illustrated liertwitb, is made 

 j|)cr. The outside lower edges are formed 

 in the shape of a chan- 

 nel that fits over the 

 top of the jar. This 

 method of construction 

 adds greatly to the 

 stiffness of the jars, 

 thereby reducing the 

 danger of breakage. A 

 little scaling compound 

 is used to make tlie 

 connection between the 

 cover and jar perfectly 

 tight and acid proof. 

 The cover is easily re- 

 moved when necessary 

 by simply heating the 

 joint with a gasolene 

 torch. [Victor Storage
