Transformers. 



62,966. Alternating Current Transformer, after Weinhold, can be taken to pieces; Figure; 



for use with open and closed magnet ic circuit (W. D. Fig. 590) 2. 4. 



The transformer has three groups of windings one group of 36 turns of thick wire, and two groups 

 each of 1,000 turns thin wire. The transformer suits Machine No. 62896. The thin winding, however, can be 

 connected for a short time to 100 120 volts when used with iron core. The following ratios can he produced 

 1:1; 1 : 28; 1 : :.:>.
