"The Pullinest Belt" 



The men in a certain munitions shop 

 were on piecework. There always was 

 a howl" when a new belt was put on. 

 They claimed no new belt would pull 

 like an old one. 



As an experiment SparOak Belting 

 was installed. Immediately the "howF* 

 ceased, because production increased 

 and, of course, the operators received 

 more pay. 



Today there is never a complaint when 

 a new belt is installed, providing it is one 

 of the pullinest" kind, as they call 

 SparOak.

SparOak Belts grip from the start. A two- 

 ply belt, the pulley side is G & K Spartan, a 

 leather with the greatest pulley-gripping power 

 ever attained in a belting material 5 the outer side 

 is the finest quality G & K oak-tanned stock. 



The oak-tanned outer ply gives rugged endur- 

 ance to withstand the severest service condi- 

 tions. The Spartan leather next the pulley 

 insures a firm grip.
