Sargent's 

 Electric Drying Oven 



With Automatic Temperature Control 



(PATENTED JANUARY 6, 1914) 



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

 in satisfactory operation prove its success. This end has been achieved bj' rugged- 

 ness of construction, elegance of design and due observance of the scientific princi- 

 ples which are demanded in drying ovens. 



Tlie ventilation is ample and the cold air en- 

 ters 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 b}- 

 the operator in two minutes. No lamps are needed 

 for setting the control and thus all glass is elimina- 

 ted. 



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,.
