DEVICE FOR SAMPLING GRAIN AND OTHER MATERIAL 



Fig. 3. — Top view of the sampling device with the hopper removed, 

 showing the upper part of the ducts around the base of the cone. 



In the opening at the bottom of the hopper the diameter of the short 

 spout directly under the valve (B, fig. 1) is slightly larger than the 

 diameter just above 

 the valve, so as to pre- 

 vent small seeds, dirt, 

 etc., from being forced 

 into the slot in which 

 the valve fits when it 

 is closed. Fastened 

 to the short spout at 

 the lower part of the 

 hopper is a shield (C, 

 fig. 1), which extends 

 part way down over 

 the cone. This shield 

 prevents the material 

 from bounding out of 

 the apparatus as it 

 falls on the cone from 

 the hopper. 



The apparatus de- 

 scribed may be con- 

 structed from any material which is sufficiently strong and durable 

 to withstand the strain of the operation to which it may be subjected 



in effecting the sampling, mixing, or 

 blending of the material specified. 

 When used for grain, seeds, or ground 

 material, it can be made of brass or a 

 good grade of zinc, both of which metals 

 are fairly rust resistant. 



OPERATION OF THE SAMPLING DEVICE. 



Place the material to be separated 

 in the hopper and open the valve or 

 gate, which allows the material to fall 

 on the peak of the cone in the form of a 

 circular column. The material then 

 spreads on the cone into a line the 

 length of the circumference of the cone 

 at its base, where it is divided into 

 sections by the ducts and the spaces. 

 The material entering the ducts passes 

 through them and falls into the inner 

 funnel and finds an exit through the 

 spout at its bottom, falling into the re- 

 ceptacle (T, fig. 1), which is placed 

 underneath the spout for receiving the 

 material. 



All of the material which enters the 

 spaces between the ducts at the base 

 of the cone falls into the outer funnel 

 and is spouted into the second container (77), which is placed below 

 the spout for that purpose. A top-surface view of the receptacles is 

 shown in figure 6.

 from the inside funnel passes through the
