additional security against the explosion of steam boilers. The 

 judges are of opinion, however, that the guage cocks should in 

 all cases be an appendage to a boiler. 



Patent Governor Valve. 

 Junius Judson, Rochester, N. Y. This is a good and efficient 

 arrangement for controling the quantity of steam upon the steam 

 cylinder when the power is thrown off, or on thus rendering the 

 motion more uniform. 



Fire Proof Iron Safes. 

 Those exhibited by Silas E. Herring, from No. 135 Water St., 

 were deemed the best by our judges, who observe that many from 

 Jhe same manufactory have proved themselves most valuable. ^ 



Iron Burglar Safes. 



From the World's Safe Co., Troy, N. Y. These are made of 

 chill'd cast iron 1^ to 2 inches thick, making it almost impossi- 

 ble for a burglar to enter it by the sides. The greatest objec- 

 tion to it is its great weight. It is worthy of a' trial, and may turn 

 out an important improvement. The inventor deserves credit. 



Bulkleyh- Electro Magnetic Enunciator 

 This is a very beautiful thing in theory, and although the 

 committee are not fully satisfied as to its practical value, they 

 consider it a very ingenious device for getting rid of the trouble 

 and cumbrous arrangements attending the ordinary Bell Hang- 

 ing fixtures, and the effort, whether successful or not, deserves 

 commendation. 



Steam Pressure Guages. 

 Joshua Lowe's, J. S. Pirsson, agent. A well made article, and 

 an improvement upon those in former use, especially for locomo- 

 tives, to which we should consider them a very good and useful 

 appendage. Show at all times the exact pressure much more 

 nearly than can be known by the spring balance attached to the 

 safety valve. 



Self-centering and self-releasing Lathe. 

 Thomas W. Bailey, Lockport, N. J. This lathe possesses 

 valuable features which may well claim attention, and which 

 are adopted to make it useful in turning wood of irregular forms.
