As the widths of the ducts are equal to the widths of the spaces 
between the ducts, it follows that the material falling on the cone is 
separated into approximately equal parts, one-half passing through 
the spaces and the other half passing through the ducts. All of the 
material which falls into the spaces is spouted into one of the recep- 
tacles, while all of the material 
which falls into the ducts is spouted 
into the second-receptacle. 
If it is desired to obtain a smaller 
part of the original amount of ma- 
terial than one-half, it is only neces- 
sary to return to the hopper the 
material which falls into either of 
the receptacles and run such ma- 
terial through the device again, re- 
peating such action as often as it. 
may be necessary to procure asam- 
ple sufficiently small for the purpose 
desired; or the same result may be 
obtained by building up a series of 
superimposed devices of the kind 
described, so that the lower deyice 
will receive only the material which 
is spouted from one of the funnels. 
If it is desired to obtain a small 
sample from a very large quantity 
of material, as, for instance, from 
either a carload or cargo of grain, 
as the grain is bemg loaded into 
or discharged from a car or vessel,

ing one leg placed on the left side halfway be Can be altered by widening the space 
eGo eye eneceDincles between the ducts so that any frac- 
tion of the material entering the hopper can be made to pass into 
the ducts and inner funnel, and by superimposing two or more de- 
vices, one above the other, the portion taken out by the ducts in eacl 
device will reduce the original material very rapidly 
to a sample of any size required. 
The device can also be used for blending two or 
more streams of wheat or other grain going to the 
rolls of a mill or mills. If itis used to blend two or « 
more streams of (say) wheat of different varieties or 
erades, it is only necessary to spout each stream into 
the hopper and to bring the two resulting streams 
together again before the mixture enters the rolls of 
the mill. To supply two sets of rolls with the same me. 6—Top view of 
blend, each stream as it leaves the device should be one gt, the Tevepta. 
run to aseparatesetofrolls. Ifitisdesiredtorunthe material to be sam- 
blend to four sets of rolls, then it would be necessary Po 
to place another device under each spout of the upper device and run the 
grain from each of the four resulting streams to a separate set of rolls. 
Note.—Application has been made for a patent covering this device; if patent is 
allowed it will be donated to the people of the United States.
