5328-5339 



Dial Rheostat, new pattern, for accurate measurements, fitted with trough for increasing 

 the ampere capacity by insulating the coils with oil, which gives the box a greater carrying 

 capacity. 



In this form the dials can be rotated in either direction, and the ends of the brushes are so bent that 

 they do not lie tangent to the circle in which they travel, and only cause a minimum amount of wear on the blocks.
