MACHINE FOR SCOURING CEREALS.

Specication of Letters Patent.

Patented J an. 21, 1919.

Application filed August 5, 1918. Serial No. 248,478.

To all whom t may concern.'

. Be it known that I, GUs'rAv E. FRIED- RICH, aA citizen of the United States, residing atjGrand.Rapids,in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Machines for Scouring Cereals, of which the following is a specification.

My invention relates to improvements in implements for scouring wheat and other cereals, and its objects are: first, to provide for removing any smut, mold or other unsanitary microbes from the wheat or such other cereal as may beunder treatment. Second, to provide a means whereby the scouring element may be used and re-used any desired number of times, and successively. Third, to provide a means whereby all microbes taken from the cereal under treatment will be absolutely removed and carried 0H during the process of scouring, and

fourth, to provide a means whereby every vestige of the scouring element, as well as the foreign matter removed will be absolutely separated from the cereal.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a front elevation of the machine. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional plan on the line 3-3 of Fig. 2. Fig. 4 is a plan of the machine. Fig. 5 is a back elevation showing the relative positions of the several driving elements of the machine, and, also, showing the hopper and scouring boxes in section on line 5--5 of Fig. 4, to show the several elements that are more directly connected with the scouring process. Fig. 6 is a detached elevation of the two scouring plates. Fig. 7 is a sectional end view of the sieve boxes, sieves and sand removing board. Fig. 8 is a. sectional side elevation of the sand removing board and spout, and Fig. 9 is a plan of one of the grain sieves.

Similar reference characters indicate similar parts throughout the several views.

The construction of this machine requires the use of a supporting frame 1, a hopper 2 and scouring boxes 3. The scouring boxes 3 are supported upon the girts 4 of .the frame 1 by means of rods 6 that are made to slide freely in their bearings on said girts so the boxes 3 may be made to reciprocate horizontally, in opposite directions by means of the eccentrics and .connections shown at 25, connecting the main shaft 2O with the scouring boxes 3 so each box will move independently of the other, and always in the opposite direction. 12 shows the driving,"and the loose pulley on the driving shaft 20, which are of such common use in like connections as to require no further description here.

'Ihe hopper 2 is divided by a partition a into two compartments, c and d. The compartment cl is for the rece tion of a properly clarified and sterilize scouring element, as sand, and is provided with a gate or trap b that may be so pivoted to the hopper, at f, that the end g may be placed close to, or removed from the partition a to increase or diminish the flow of the scouring element over the gate and through the opening e to the scouring plates 24. The grain enters into the compartment c of the hopper and iows, with the scouring element, through the opening e between the scouring plates 24. The plates 24 are pivotally mounted upon the supporting rods 6 in the scouring boxes 3 and may be adjusted to increase or diminish the distance between their lower ends, by means of adjusting screws 14, and are made to reciprocate horiz ontally with said boxes, in opposite directions, so the wheat, or other cereal,and the sand or other scouring element will be made to intermingle, backward and forward, so constantly and thoroughly that every particle of the surface of the cereal, including the .grooves in wheat, barley, rye, and other grains will be thoroughly scoured, and all foreign matter absolutely removed. The scouring plates 24 are serrated, as indicated in Fig. 6, in such a manner that the serrations will lie in opposite directions to insure the perfect distribution of the cereals and scouring elements over the entire surfaces of the plates. The discharge opening below the plates may be regulated by means of the gates 19 actuated by the screws 15. The said gate b is actuated by the screw 13.

The s( niring element is stored, in small quantities, in the elevator shaft 7 whence it is carried upward and discharged into the spout 17 and into its compartment of the hopper, whence it passes through between the scouring plates 24, and, with the cereal, onto the upper surface of the upper sieve 27, whence the scouring element passes directly through both sieves and into the receiving hopper 8, and through the spout 9 back into the lower end of the elevator shaft to be iio again taken up and carried back into the hopper 2, thus working. 'the same scouring. element continuously and repeatedly as the cereal is passed through the machine'. The elevator is operated by the belt 29, from the pulley 28 on the main shaft 20, over the pulley 28, in the usual way. As this form of elevator is common, well known, and does not really form an element of invention at this date, 1 do not deem it necessary tofenter further into details of construction or operation. rlhe sieve holder 5 isA suspended from the lower girts 4 by means of springs 10, in such a manner that they may be made to reciprocate horizontally to thoroughly sieve the particles of scouring material, and remove bacteria after the cereal has been properly scoured and before the cereal has beendischarged from the machine. Thehacteria or smut, rust, mold and other foreign matter is removed from the si'eves'v by meansl of a blower 1S sucking said foreign matter l"through the conductor pipe 16, the blower 18 being driven from the counter shaft 22 by means of the belt 23, in the usual manner, the counter shaft 2Q being driven by the belt 21, from the main shaft 20. The oscillating, or horizontally reciprocating movement of the sieves,and the sand hopper 84-9 Ais produced by means of an eccentric 26 on the .counter shaft 22. This movement is given to insure the proper movement ofthe cereal, 11, over, and of the sand' l1 through the sieves 27. 112, in Fig. a, represents the discharge of smut, &c., from the blower 18.

rlhe removal of the scoured cereals from the machine may be provided for by any of the well known means provided in this class of machines, as, for instance, by the use of a sieve 30 and a discharge spout 31, so arranged that when the cereal has passed over the sieves 27 and the scouring element and refuse have been disposed of the cereal will be made to pass out of the machine, thoroughly cleaned, over the spout or plate 31 into any desired receptacle. I give this simply as an available means, but not as an essential means for bringing about this necessary result.
