IMPROVEMENT l-N GR'AlN-TEST'ERS.
Specification forming, part of Lettere` Patent No. l 70,545, dated November 30, 1875; application filed october 23,1815.
same, reference being had to the annexed' drawings, making a part of 'this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a representation ot' a plan view of our grain-tester, and Fig. 2 is a View of the stopper. Fig. 3 is a longitudinal central sectionalview of our grain-tester, and Fig. 4 is a transverse sec' tional viewthereof.
This invention has relation to instruments which are used for testing grain for the purpose of ascertaining the quality of, andthe amount of impurlties therein.
The nature ot our vinvention consists in two perforated tubes, arranged one inside of the other, and having perforations through them, one row of which is covered with wire-gauze, a removable stopper, and a handle, which is secured to one end of the inner tube, for turning it, as will be hereinafter explained.
In the annexed drawings, A designates a case or cylindrical tube, which may be of any desired diameter and length. This tubeA has two rows of perforations, d h, through it, arranged diametrically opposite 'each other, over one row, h, of which, wire-cloth, or its equivalent, is applied, as shown in Figs. 3 and 4. Inside of tube A is a tube, G, having one row of perforations, g, through it, arranged at the same distance apart as the perforations through the tube A, so that when tube C is adjusted, as shown in Figs. 3 and 4, the perforations g h will register with each other, and impurities in the grain contained in the instrument can be sifted into a conductor, G,
and from it emptied into the gage-cup E, which is marked oft in ounces and fractions thereof. The two tubes A C are held together by, means of a pin, c, which is fixed to tube C and passed through a semicircular slot, b, in tube A. B designates a pointed stopper, which is fitted into the end of the tube A, and which is removable for the purpose of emptying grain out of the instrument after completing a test. D designates the handle ot' the instrument, which is secured into one end of the inside tube C, and used for handling the instrument and adjusting the tube C about its axis. y
The tube A should be properly marked oi' to indicate pounds and fractions of thismeasure.
In practice, the cup E will be made to t on the discharge-orifice of the conductor G.
To use the instrument, the tube Gis turned so that the perforations g d register with each other. The instrumentis then plunged into the grain to be tested, and Worked around. Before withdrawing the instrument from the. grain the inner tube C is turned half around, so as to bring the perforations g h together. The instrument is then held horizontally and shaken, which will cause the foul seeds, Ste., to fall into the conductor G.
What we claim as new, and desire to secure 'by Letters Patent, is-
An instrument for testing grain, consisting of the perforated tubes a c, and wire-clothv coveringthe perforations h, in combination with a conductor, substantially as described.
In testimony that We claim the above we have hereunto subscribed our lnames in the presence of two witnesses.

C. G. MAYBURY, F. D. HYDE.
