The demand on belts varies enor- 

 mously. Some must loaf along with 

 light loads ; some run slowly and some 

 run quickly with heavy loads ; and some 

 must contend with trying conditions 

 like steam, fumes, or exposure to heat. 



For each and every set of power re- 

 quirements the Graton and Knight 

 Standardized Series leather belting 

 presents a belt made specifically for 

 this purpose. 



Blower belts that rush along a mile 



a minute must have great elasticity, 

 high surface traction and must stand up 

 under trying conditions. For this ex- 

 acting work, the Graton & Knight 

 Spartan Belt, with its wonderful elas- 

 ticity and pulley-grip, is ideal. It resists 

 conditions of exposure, heat, steam, 

 chemical fumes that cause most belts 

 to disintegrate. 



It is a fine example of the benefit of 

 Standardization applied in belt making.
