 >092 T Falja's Hopper, for determining the weight per bushel of cement. 



This machine is arranged so that the hopper into which the cement to be weighed is put has no direct communi- 

 ation with the bushel measure which is placed under it, but by turning a handle the cement is wormed to an 

 pening immediately over the centre of the measure, and the cement therefore falls into it at a uniform pace, 

 nd fills it to a uniform density, thus ensuring an absolute comparative determination between the weights of 

 ifierent cements.
