THE AUTOMATIC CYCLOSTYLE. 



THE LATEST IMPROVEMENT. IN DUPLICATING APPARATUS. 



For printing Reports, Speci- 

 fications, Price Lists, etc., it is 

 invaluable and soon repays its 

 cost. 



A FEW ADVANTAGES. 



i.— No skill required, The 

 work being done by the 

 Machine automatically, a 

 novice can at once obtain per- 

 fect copies. 



2. — Great uniformity of 

 copies. The pressure being 

 constant and regular, the 

 copies are all alike. 



3.— The process of re-ink- 

 ina is made much easier and 



cleaner. One inking suffices 

 for 100 to 200 copies, but 2,000 

 copies may be taken from one 

 stencil. 



4.— Equally adapted for re- 

 producing written or type- 

 written matter. 



5. — Great speed in taking 

 copies. It is only necessary 

 to turn a handle which lifts and 

 lowers the frame, and time is 

 gained by having a less number 

 of re-inkines. 



6.— The difficulties which fre- 

 quently arise in the working 

 of other duplicating apparatus 

 entirely dispensed with in the 

 CYCLOSTYLE.
