DEVICE FOR SAMPLING GRAIN AND OTHER MATERIAL. 3 
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. Thisshield 
prevents the material 
from bounding out of 
the apparatus as it 
falls on the cone from 
the hopper. .

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.

ue aa 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 
7 circular column. The material then 
spreads on the cone into a line the 
L| length of the circumference of the cone 
at its base, where it is divided into 
sections by the ducts and the spaces. 
iN The material entering the ducts passes 
<I through them and falls into the inner 
9 1 me funnel and finds an exit through the 
spout at its bottom, falling into the re- 
g ceptacle (7, fig. 1), which is placed 
underneath the spout for receiving the
