Tousey & Reed's Chronometer Steam Engine. 



No. 15. — Chronometer Steam Engine. 

 Tousey & Reed, 95 Maiden Lane. This impro-vement consists 

 in letting the steam in and out on both sides of the cylinder, and 

 cutting it off close to the piston. By this means the pressure 

 and friction is entirely removed from the valves. It also dis- 

 penses with the friction and weight of excentrics, cross-heads, 

 connecting rods, and rock shafts. It is well adapted for portable 

 purposes when attached to the boiler. [^ silver medal atoarded. 



JVo. 1968 — Oscillating Steam Engine. 

 Darlington & Co., Centre cor Franklin st., is the best oscillating
