Statistics of Patents. 



MR. J. S. BROWN, of Washington, has recently published a catalogue of all the patents 

 granted by the United States Government up to the commencement of the year 1855. From 

 this we learn that the whole number of patents granted for Grain and Grass Harvesters has 

 been one hundred and eleven; for Plows, three hundred and seventy-two; for Straw- Cutters, 

 one hundred and fifty-three; for Smut machines, one hundred and forty; for Winnowing 

 machines, one hundred and sixty-three, and for Threshing machines, three hundred and seventy- 

 eight. The highest numbers in classes belong to the agricultural department, with the 

 exception of Stoves, on which the enormous number of 682 patents have been issued, and 

 478 for designs, making a total of 1160 patents on Stoves. 



On Air Engines, not one of which is in use, no less than twenty-one patents have been 

 granted. No less than 148 patents have been granted on Steam Boilers; and yet, for all this, 

 there are but few engineers who do not entertain the opinion that many improvements have 

 yet to be made on them. The manufacture of India-rubber goods is but of recent date, and 

 yet no less than forty-two patents have been obtained on such manufactures. Sewing 

 machines are of still more recent date, the first patent having been obtained in 1846, only 

 nine years since ; and yet no less than sixty patents have been granted on such machines. 

 This affords evidence of their popularity and usefulness. The number of Water-Wheel 

 patents is somewhat high, being 327, but that of Washing machines comes nearly up to it, 

 being no less than 309.
