PAUL GROBECKER, OF ARTERN, SAXONY, GERMANY.

APPARATUS FOR TESTING GRAIN.

SPEGIFIQATEON forming part of Letters Patent No. 381,469. dated April 17, 1888.

Application filed September 14, 1887. Serial No. 249,616.

(No model.) Patented in Germany November G, 1886, No. 39,622; in

England November 29, 1836, No. 15.569, and in Austria-Hungary Aprile, i887, No. 46,594 and No. 11,700.

To all whom it may concern:

Beit known that I, PAUL Gnonnciinn, of Artern, Saxony, Germany, have invented certain new and useful Improvements in Apparatus for Testing Grain, (for which Letters Patent have heretofore been granted to me in Germany, No. 39,622, dated November 6, 1886; in Great Britain, No. 15,569, dated November 29, 1886, and in Austria-Hungary, No. 46,591 and No. 11,700, dated April (i, 1887,) of which the following is a specification.

The object of my invention is to provide a new and improved apparatus for cuttinggrains transversely, so as to obtain a clean-cut crossseetion of the same to facilitate examining them.

The invention consists in the combination, with a cup or receptacle having tapered apertures in its bottom, of a plate hinged to the under side of said cup and provided with cor. responding apertures, and a cutter pivoted between the cup and the plate.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is alongitudinal sectional elevation of my improved device for cutting grains, the handles being shown in elevation and the cup and the plate being so adjusted that their apertures coincide. Fig. 2 is a plan view of the same, the cutter or blade being swung from below the receptacle, parts of the receptacle being in section. Fig. 3 is a cross-sectional view of the plate and a hinged check-plate on the under side of the same on the line x m, Fig. 2. Fig. 4 is a cross sectional view on line y y, Fig. 1.

l Similar letters of reference indicate corresponding parts.

The cup-shaped receptacle a, which has a handle, a', is provided in its bottom with aseries of apertures, a2, which are tapered from the upper to the lower surface of the bottom of the said cup-shaped vessel a. The plate b is of the same diameter as the cup a, and is provided with a handle, b', which is pivoted to the handle a by the pivot c, and said plate b is provided with a series of apertures, b2, co-

inciding with the apertures of the cupa, which apertures b2 also taper from the upper to the lower surface of the plate b, the upper diameters of the apertures()2 being the same as the lower diameters of the apertures a?.

The handles a b are preferably made of spring metal, and the handle b is provided at its free end with a nose, g', which can pass into the notch g2 in the bent end of the handle b' for the purpose of holding the plate bin such a position in relation to the cup a that the axes of the several aperture a2 b2 coincide, the spring-tension ot' thehandl'es keeping the nose g in the notch g2.

A disk-shaped blade, h, is mounted to turn on the pivot c, and to swing in between the under side of the cup a and the upper-surface of the plate b, said disk-shaped blade 7L being provided with a handle, h', arranged-between the handles a b. the edge with a downwardly-projecting screw, e, on which a lug, d', is mounted to turn, said lug projecting downward from a plate, d, at the edge, which plate d is provided diametrieally opposite to the lug d' with a spring-catch, j', the free end of which is adapted to engage a notch, f, on the plate b. The plate d is also provided at its upper side with tapered apertures d2, which coincide with the apertures a? and b". As the lug d is mounted on the screw e, it is evident that by turning the plate in one direction it is moved from the under side of the plate b and by turning it in the other direction it is moved toward the plate Z1, thus permitting of adj usting the plate d at a greater or less distance from the under side of the plate b. This'is necessary, as the grains have various lengths.

The operation is as follows: The plate d is adj usted, in the manner set forth, a greater or less distance from the under side of the plate b, according to the length of the grains, and locked in place by the springf. The blade or cutter h is swung from under the cup a into the position shown in Fig. 2, and a quantity of grain placed in the cup a, which cup is then shaken, so that the grains pass into the apertures a2 b2 d2 and stand vertically in the same. The handle h of the cutter h is then swung in the direction of the arrow w, Fig. 2, so as to The plate b is provided at 7 IOO lwith a handle pivoted to the handle of the cupshaped vessel, which plate is also providedwith tapered apertures in line with those of the vessel, and a blade pivoted between the two handles to swing between the upper surface of the plate and the under side of the cup-shaped vessel, substantially as shown and described.

2. The combination, with a cup-shaped vessel having tapered apertures in its bottom, of a plate pivoted to the under side of the cupshaped vessel and also provided with apertures coinciding with those in the bottom of the vessel, a check-plate pivoted to the under side of the abovementioned plate and also provided with tapered apertures the centers of which coincide with those of the apertures in the other plate and the cup-shaped vessel,

. invention I have signed my name in and a blade pivoted between the cup-shaped vessel and the plate pivoted to it, substantially as shown and described. l

3. The combination,with the cup shaped vessel a, having tapered apertures a2 and the handle a', of the plate b, having tapered apertures b2 and handle b', the pivot c, by which the handles a b are pivoted together, and the blade'h, mounted on the pivot c at the under side of the cup a, substantially as shown and described.

4. The combination, with the cupshaped vessel a, having the tapered apertures a?, of the plate b, having the tapered apertures b2, the plate d, provided with the lug d, the screw e, projecting downward from the plate b, on

which plate the-lug d is mounted to turn, the

catchy, and the blade h, pivoted between the cup-shaped vessel and the plate b, substantially as shown and described.

In testimony that I claim the foregoing as my presence of two subscribing witnesses.
