 ELECTRIC DRYING OVEN 



With Automatic Temperature Control 



(Patented Jan. 6, J9I4) 



This is the pioneer of moderate-priced ovens in this class, and the hun- 

 dreds now in satisfactory operation prove its success. This end has been achieved 

 by ruggedness of construction, elegance of design and due observance of the 

 scientific principles which are demanded in drying ovens. 



The ventilation is ample and the cold 

 air enters through the bottom and passes 

 upward, being heated by the heating coils 

 before reaching the sample. The heating 

 units are of the simplest construction and 

 may be rewound or replaced by the opera- 

 tor in two minutes. No lamps are needed 

 for setting the control and thus all glass is 

 eliminated. 



Its extreme simplicity precludes the imitation of its patented features 

 and enables it to maintain its position as the best and cheapest apparatus on 

 the market for its purpose.
