GRAIN TESTER.

Application led May 18, 1925.

The invention relates to improvements in grain testers and an object of the invention is to provide a tool whereby a person, such as a grain merchant, can quickly and effectively test a sample of grain.

A further object of the invention is to previde a. simply constructed, inexpensive, durable and easily operated tool and one which can be readily adapted for testing various kinds of grains.

With the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claim, reference being had to the accompanying drawing in which:

Fig. 1 is a perspective view of the tester with the knife in Open position.

Fig. 2 is a vertical sectional view longitudinally and centrally through the tester and with the knife open.

Fig. 3 is a plan view of one end of the tester with the knife open and the pressure 25 disc removed.

Fig. 4 is an inverted plan view of the parts appearing in Fig. 3.

In the drawing like characters of reference indicate corresponding parts in the several `figures.

The tester comprises four main parts; a cup 1, a knife 2, a holder 3 and a pressure disc 4. The cup, knife and holder are all supplied with handles 5, 6 and 7 respectively, the handles being pivotally connected together by a fastening bolt 8 fitted with a nut 9.

It is to be observed that the knife operates between the cup and the holder and that the knife handle can swing in between the other handles, a space 10 being reserved for this purpose between the handles 5 and 7. The ends of the handles 5 and 7 are fitted with opposing complementary stop plugs 11 and 12 which stop the said handles from turning in one direction after they have been brought to the position shown best in Figure 1.

The knife 2 might be called a circular or Serial No. 31,225.

shearing knife and it is arranged to cutv across the face of the holder 3.

The cup 1 is provided with a perforated bottom as indicated at 13 and the yholder 3 is supplied with perforations 14 forming pockets opposing the perforations 13 when the tester is closed. The perfo-rations and pockets are forme'dwith due regard t0 the particular grain which is to be tested.

At the side opposite pin 8 the cup 1 is provided with a retaining finger 1 shaped to t beneath and support the adjacent edge of the holder 3 when the'latter is in closed position as shown to advantagepin Figure 2.

In the present instance a sample of wheat 15 is being tested and the perforat-ions 13 are of such a nature that they will allow the wheat kernels to press through in an end on position and the pockets 14 are such that they will receive and support the lower ends of the said kernels, it being understood that Ehe knife is at this time in the open posi` ion.

When one wishes to test a sample of wheat he puts the sample in the cup and then shakes the cup to cause a quantity of the kernels to take anend on position with their lower ends seated in the pockets, the knife blade being at this time open. He then inserts the pressure member o-r disc 4 and whilst pressing down on it he draws the handle 6 inwardly between the handles 5y and 7, such resulting in the cutting in two by the knife blade of the kernels caught in the pockets. After cutting he swings the knife blade and cup to the side and this exposes the horizontally cut kernels held in the pockets. One can then examine these for toughness, frost or vermin as is customarily done.

In connection with the tester I might remark that I will make sets of cups and, holders having the perforations and pockets designed for various kinds of grains so that with a set of these one could test the vario-us grains as desired.

What I claim as my invention is: y

In a grain tester, a cup for receiving the sample t0 be tested having a perforated bottoni and provided with un extending handle, a holder normally located beneath the cup and having pockets therein opposing the perlorations, said holder being provided with an extending handle, n cutting knife interposed between the Cup and the holder, seid' cutting knife being provided with an extending handle, a pin pivotnlly connecting the handles together, :i Weighted disc loosely inserted Within the cup und u re- 10 taining linger carried by the cup at the Side reinote iti-oni the pin and receiving the :xdjncentedge of the closed holder.

Signed :it Vrlinnipeg this 30th day ol -pril, 1925.
