GRAIN SAMPLER
Henry K. Holman, Washington, D. 0.; dedicated
to the free use of the Public in the Territory of
the United States of America
Application January 4, 1937, Serial No. 118,980
1 Claim. (01. 83-45)
(Granted under the act of March 3, 1883, as
amended April 30, 1928; 370 0. G. 757)
This application is made under the act of tened to and on opposite sides of the tube I.

lower ends of sleeves 6 and stop. They are of a
scribed to the free use of the Public in the terri
size to prevent their passing through the sleeves.
O tory of the United States of America to take effect
A metal eye bolt l2 attached to and extending 1O
upon the granting of a patent to me.
My invention relates to a sampling device for
obtaining samples of grains stored in bulk in
tanks, bins, or other bulk grain storage contain
1 ers and the object of the device hereinafter de
scribed is to enable one to draw samples of grain
from such containers, without having to climb
down into them. I attain this object by the de
vice illustrated in the accompanying drawing in
2 which Fig. 1 is a detailed view of the entire de
vice showing the valve closed and the metal
point reversed in the tube to facilitate trans
portation and Fig. 2 is another view of the device
with the valve open and the metal point posi
2 tioned to sample grain.
The device consists of a metal tube l, ?tted
at one end with a solid metal point 2. This point
is held in place at the lower end of the tube by
means of two screws 3 on opposite sides of the
30 tube. These go through apertures in the tube,
and into threaded holes in the metal point 2.
When not in use, the screws 3 may be removed
3
and the metal point 2 reversed in the tube to
facilitate the transporting of the device, as
shown in Fig. 1.
4
4 designed and positioned to close and open the
upper end of the tube. The valve is supported by
two rods 5 paralleling the sides of the tube l.
These rods 5 are held in place by two sleeves 6 fas
At the open or top end of the tube is a valve
upwardly from the valve 4 affords a means of
attaching a rope 13. The device, with rope
(one end is held by operator) attached, when
dropped through an opening into a bin contain
ing grain, plunges into the grain. It penetrates 15
beneath the top surface of any grain in a bin
su?iciently deep ordinarily to reach grain that
is not chaify. After maximum penetration has
been attained, the operator gives the rope a steady
pull. This opens the intake valve 4 allowing 20
grain at that point to ?ll the container of the
device through the opening H, shown in Fig. 2.
This requires but a few seconds. Next by means
of the rope the operator withdraws the device
?lled with the desired sample of grain, from the
bin.
Having fully disclosed my invention, I claim:
A grain sampling device comprising a tube, a
removable weighted point ?tted closely into, at
tached to and extending downwardly from one
end of the tube, a valve at the other end of the
tube designed and positioned to open and close
that end of the tube, rod members rigidly at
tached to the valve and slidingly secured to the
walls of said tube, means attached to the valve
to move said rod members along the sides of the
tube and means attached to the tube and rod
members to limit the movement of said rod
members.
HENRY K. HOLMAN.
