2 Claims. 1
This invention relates to new and useful improvements and structural refinements in grain probes, and the principal object of the invention is to facilitate the gathering of proper specimens or samples of grain at different levels of a storage bin, or the like.
Conventional grain proves customarily embody in their construction a vertically elongated, tubular barrel provided with a row of vertically spaced openings, and a tubular receptacle which is rotatably disposed in the barrel and is also provided with a row of vertically spaced openings which are registrable with the openings in the barrel so that when the probe is inserted into the grain, the receptacle becomes filled with samples of the grain, which are subjected to examination after the probe is withdrawn.
However, inasmuch as various impurities are usually heavier than the grain itself, they tend to gravitate toward the lower strata of the grain and when the conventional probe is inserted in its sampling position, the receptacle of the probe usually fills from the upper strata and impurities in the lower strata often become undetected.
The principal object of the instant invention is to eliminate this disadvantage by the provision of a probe wherein the openings in the barrel and in the receptacle are so arranged that the openings adjacent the lower end of the probe come in register first, that is, so that the openings become registered progressively and successively from the lower end to the upper end of the probe, whereby the receptacle of the probe is filled in the same fashion and accurate gathering of the grain samples is facilitated.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational view of the invention;
Figure 2 is a side elevational view of the tubular receptacle per se; and
Figure 3 is a vertical sectional view taken substantially in the plane of the line 3-3 in Figure 1.
Referring now to the accompanying drawings in detail, the grain probe is designated generally by the reference character and embodies in its construction a tubular barrel l2 having a pointed lower end [4 and an open upper end l6 while the usual tubular receptacle I8 is rotatably disposed in the barrel l2 in the conventional manner.
The barrel I2 is provided with a row of vertically spaced and circumferentially aligned openings 20, while the receptacle I8 is provided with a row 2 of vertically spaced but circumferentially staggered openings 22.
When the device is assembled as shown in Figures 1 and 3, the openings 22 in the receptacle l8 are registrable progressively with the openings 20 of the barrel, in succession from the lower end to the upper end of the barrel. This is best illustrated in the accompanying Figure 1, wherein it will be noted that while the lowermost of the openings 20 is unobstructed, the uppermost of the openings 20 in the barrel is closed by the receptacle 18. As the receptacle is rotated within the barrel in a counterclockwise direction, the openings 20 will become successively and progressively cleared, in an upward direction from the lower end of the barrel, so that when the device is placed in use and is inserted in a body of grain, the receptacle ill will become filled from the bottom to the top. In this manner, accurate sampling will be achieved, and of course, after the receptacle is filled and the probe is withdrawn, the grain may be emptied through the usual open upper end 24 of the receptacle in the conventional manner.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
What is claimed as new is as follows:
1. A grain probe comprising a tubular barrel provided with a row of vertically spaced openings, and a tubular receptacle rotatable in said barrel and provided with a row of vertically spaced but circumferentially staggered openings registrable progressively and successively with the first mentioned openings upon rotation of the receptacle in the barrel.
2. A grain probe comprising a tubular barrel having upper and lower ends and provided with a row of vertically spaced and circumferentially aligned openings, and a tubular receptacle rotatable in said barrel, said receptacle being provided with a row of vertically spaced but circumferentially staggered openings registrable progressively with the first mentioned openings successively from the lower to the upper end of the barrel upon rotation of the receptacle in the barrel.
