No. 216.] 131 



This apparatus is composed of a small steam boiler or generator; 

 a contluctor from which leaJs into a hopper, (or a box opened at 

 top and bottom,) containing numerous small horizontal pipes be- 

 tween which the grain descends; conductors open at the under side, 

 and placed under each of the above steam pipes in such a manner 

 as to take up the evaporations thrown oft from the moist grain — -re- 

 moving it at once from contact, the dijing hopper is elevated above 

 the steam boiler by which the condensed steam is returned immedi- 

 ately back through an exit pipe leading into the same; and by which 

 no waste of water in the boiler is sustained; and as no great press- 

 Aire of steam is required, the apparatus is perfectly safe. 



Through this apparatus a very considerable stream of grain may 

 without interruption descend from a loft above, and be discharged 

 upon a floor beneath with very trifling labor. 



A modification of the same thing is adapted to the drying of meal 

 or flour, equally ingenious and important in its results. 



Your committee deem this apparatus one of the very best things 

 exhibited at the 20th annual fair of the institute — the same is worthy 

 of the notice of millers and merchants dealing in grain, particular- 

 ly of the latter. 



Ship Pump. 



A pump for this purpose was exhibited by Messrs J. W. & J. H. 

 Von Schmidt of New- York, and for which a gold medal was awarded. 



This pump acts upon the centrifugal force principle, and having 

 no valves, is not liable to choke with floating grain or other sub- 

 stances, and is thereby highly adapted to vessels transporting grain 

 in bulk. Articles of much larger size than corn pass through this 

 pump with perfect freedom, the same is capable of discharging a 

 heavy stream, and in all respects a desirable article. 



Cotton Compressing Machine. 



Your committee visited a full size operating press of this kind in- 

 vented by Perry G. Gardiner of the city of New-York, and for 

 which a gold medal was awarded. 



This cotton press is capable of reducing a bale of cotton to about 

 one third the size of a bale as it comes from the plantation press, 

 and is worthy of the notice of ship-owners.
