THE AUTOMATIC CYCLOSTYLE. 



TRE LATEST IMPROVEMENT IN DUPLICATING APPARATUS. 



FUETHER IMPROVEMENTS JUST MADE. 



For printing Reports, Speci- 

 fications, Price Lists, &c., it 

 is invaluable and soon repays 

 its cost. 



A FEW ADVANTAGES. 



1. — No skill required. The 

 work being done by the 

 Machine automatically, a 

 Hovice can at once obtain per- 

 fect copies. 



2. — Great uniformity of 

 eopies. The pressiu-e being 

 constant and regular, the 

 «opies are all alike. 



S. — The process of re-ink- 

 iHg- is made much easier and 



cleaner. One inking suffices 

 for 100 to 200 copies, but 2,000 

 copies may be taken from on« 

 stencil. 



4. — Equally adapted for re- 

 producing written or type- 

 written matter. 



5. — Great speed in taking 

 copies. It is onlj' necessary 

 to turn a handle which hfts 

 and lowers the frame, and time 

 is gained by having a less 

 number of re-inkings. 



6. — The difliculties which 

 frequentljr arise in the working 

 of other duplicating apparatus 

 entirely dispensed with in th« 

 CYCLOSTYLE.
