 STEAM ENGINE 



THE Rotary Steam Engine has 

 attracted the best thoughts of 

 inventors and students for many 

 years. All interested should read 

 carefully the very complete in- 

 formation found in the files of the 

 Scientific American Supplement. 

 Every class and type of rotary 

 engines and pumps is described 

 and illustrated.

 travels entirely around an annular cylinder. 



Scientific American Supplement 1524 describes 

 Rotary Engine on the intermittent-gear principle. 



Scientific American Supplement 1534 contains 

 a valuable column on the difficulties of rotary en- 

 gine design. 



Scientific American Supplement 1821 contains 

 an article describing many new forms of rotary 

 engines of the most modern design. 



Scientific American, No. 23, Vol. 102 contains a 

 full description of the recent Herrick Rotary En- 

 gine, an eccentric type with swinging abutment.

 incorporated in the sliding-valve design. 



Each number of the Scientific American or 

 the Supplement costs 1 cents. A set of 

 papers containing all the articles here men- 

 tioned will be mailed for $2.00. They give 

 more complete information on the subject 

 than a library of engineering works. Send
