THE AUTOMATIC CYCLOSTYLE, 



THE LATEST IMPROVEMENT IN DUPLICATING APPARATUS. 

 FURTHER IMPROVEMENTS JUST MADE. 



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- 

 lng is made much easier and

recommend this Machine to 



Scientific Societies and others 



fold copies of notices or 



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-inkings. 



6. — The difficulties which fre- 

 quently arise .in the working 

 of other duplicating apparatus 

 entirely dispensed with in the 

 CYCLOSTYLE.
