MACHINE FOR SCOURING CEREALS.

Application filed January 27, 1919.

To all whom it may concern Be it known that I, GUSTAV E. FRrnDRroH, a citizen of the United States, residing at Grand 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 machines for scouring and cleaning cereals, and its objects are: First, to provide a means whereby the scouring and cleaning may be done rapidly and inexpensively; second, to provide a means whereby the quantity of cereal to be cleaned may be automatically governed by the cleaner; third, to provide a means whereby the scoured cereals may be conveyed to, and deposited into any desired receptacle as fast as scoured.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a transverse vertical section of the operating cylinder practically on the line 33 of Fig. 8. Fig. 2 is an elevation of the scouring arms and shaft. Fig. 3 is a sectional elevation of the scouring cylinder practically on the line 11 of Fig. 1. Fig. 4: is a plan of the machine complete.

Similar numerals indicate similar parts throughout the several views.

"approximately as shown in Fig. 3. This case or cylinder is provided with a receiving hopper 10 into which the cereals are delivered to be carried into the case by means of any available form of conveyer, as indicated at 11.

To complete the operative machine I mount a shaft 8 upon the supporting frame 1, and provide this shaft with a driving pulley 7 by means of which it may be made to revolve by any of the well known means in use for this purpose. Upon the suspended end of this shaft, and within the cylinder or case 2-%16, I mount a set of diverging arms 4, each arm having a number of laterally projecting studs 6 Specification of Letters Patent.

that are so distributed as to be made to pass alternately between the rows of studs, 5, on the sides or disks 2 and 3 for the purpose of gradually moving the mass of cereals ever upwardly and outwardly toward the spout or discharge 12. Thus, with the arms 4 made to revolve in the direction indicated by the arrows in Figs. 2 and 3 it will be readily understood that cereal entering at 11 will be made to move to the right as it enters the cylinder, and will be carried around in this direction over the lower surface of the cylinder and upwardly to the discharge spout 12, and during all of its travel the movement of the studs 6 among the studs 5 will cause the cereal grains to constantly rub upon, and intermingle with each other, and with the surfaces of the studs, thus effectually removing foreign matter by constant and repeated friction.

The conveyor 11' is made to revolve from the shaft 8 by means of any available form of belt connection, as indicated at 9 in Fig. 1. The discharge of the cereal from the machine, after scouring, is governed by the gate 13, which is pivotally mounted in the spent 12, as at 17, and arranged to stand, normally, closed and to be forced open by the pressure of the cereal as it is being forced upwardly and against the gate, and the pressure of the gate against the approaching cereal is governed by the weight 14 which may be moved toward, or from v the gate upon the arm 18, to increase or diminish the pressure against the cereal and control the discharge of cereal accordingly.

The discharge tube is placed upon, or near the vertical center of the cylinder so that the grain will be thoroughly intermingled and scoured as it is forced down one side of the machine and upwardly at the other side of the machine to the discharge pipe.

15 indicates braces for supporting the arms 4.

I prefer that the studs 5, especially those located back of the arms 4, be formed and supported upon a separate disk, as indicated at 19 in Figs. 1 and 3, and the disk secured to the cylinder plate 2 by means of screws, bolts, or other available means, as indicated in Fig. 3, as by this means I am enabled to remove the disk and studs for repairs, when necessary, and thus avert the necessity of constructing an entirely new cylinder in case of accident to the studs. Furthermore, by this means the studs may be cast integral with the disks,

thus avoiding the unnecessary expense of otherwise attaching them to, or connecting them with the disks.

What I claim as new in the art, is

In a machine for scouring cereals, a receiving cylinder having laterally disposed studs extending inwardly from each side of the cylinder, a shaft concentrically mounted in the cylinder, arms mounted upon said shaft within the cylinder, studs extending at right angles from each side of the arms and arranged to pass between the rows of studs on the sides of the cylinder, a hopper and a conveyer for feeding cereals into the cylinder, a discharge spout upon the periphery of the cylinder opposite from the inflow side of the cylinder and near the horizontal center line of the cylinder, a gate pivotally mounted in said spout, an arm connected with the gate, and a weight mounted upon the arm and arranged to govern the outflow of the scoured cereals by increasing or diminishing the pressure of the gate against the cereal by the position ofthe weight on the arm. 7
