Letter of the Commissioner- of patents to the Secretary of State of 

 the United States. 



Patent Office, May 5, 1835. 

 Sir — In reply to your letter of the 3d 'inst., requesting my 

 opinion^whether or no the stove invented by Jordan L. Mott, for 

 burning refuse anthracite coal is useful and important, I have 

 the honor to state, that in my judgment it is both useful and im- 

 portant. . In my opinion the invention involves a beautiful ap- 

 plication of philospliical principles to the purpose for which it 

 was designed, and was at the time it was made new, and has 

 since proved by practical experiments to be of great utility 



I submitted the matter of your inquiries to the examijjer who 

 has charge of that class of inventions, and he concurs with me in 

 the opinion above expressed, as you will perceive by his report to 

 me herewith enclosed. 



I have the honor to be, . 



with great respect, your ob't serv't, 

 (Signed) EDMUND BURKE. 



Report of the Principal Examiner of Patents. 



Patent Office, May 5, 1848. 

 Sir — In compliance with your request for my opinion as to 

 the utility and importance of the stove invented by Jordan L. 

 Mott, for burning small coal, I have the honor to state that I 

 have for several years been well acquainted with this invention, 

 and regarded it as highly useful and important. It appears to 

 stand quite prominent among the great collection of improve- 

 ments in stoves, as making a disti?ict era in fuel-saving. To the 

 best of my belief and knowledge, the kinds of coal for which 

 this stove was contrived, were considered useless before this in- 

 vention. Respectfully submitted. 



(Signed) CHAS. G. PAIGE, 



Examiner of Patents. 

 Hon. Edmuwd Burke, Commissioner of Patents.
