EXCORIATING GONVEYER.

Application filed October 27, 1923.

The improvements relate to conveyers for wheat and other grain, and more particularly to conveyers in which the grain is propelled by moving blades or the .like mounted in a-suitable casing, or conduit, through which the grain is conveyed, and in which it is secured or excoriated.

Among the objects of the improvements are'to provide a conveyer of the character described with strong, durable and efficient means for propelling and scouring the grain, before the milling operation, which may be easily manufactured, assembled, and operated, and will not become clogged or otherwise impaired by the grain, dirt, hulls, or other matter removed therefrom, will do its work quickly and thoroughly, and will not have an injurious action thereon.

In the accompanying drawings, Figure 1 is a side elevation of a scouring conveyer embodying the improvements, the box or casing enclosing the operating parts being broken away at one end to expose the interior; Fig. 2 is a plan of the same with the top of the casing removed; Fig. 3 is a transverse vertical section on the line 3-3 of Fig. 2, looking in the direction indicated by the pointers in that figure; Fig. 4 is an enlarged longitudinal section of the discs on which the blades or flights are mounted, with the shaft, one of the flights and mounting rods in full lines taken substantially on the line -1--1 of Fig. 5, looking in the direction indicated by the pointers in that figure; Fig. 5 is a transverse section of the shaft showing the parts illustrated in Fig. fc in end elevation.

The shaft 1 is driven by a pulley 2 and is mounted. in suitable bearings 3 and 1 in the ends 8 and 9 of the conveyer box. On the opposite end it is provided With a gear 5, which meshes with the gear 6 on the shaft 7, so that the said shaft is driven therefrom and rotates in the opposite direction. The box has sides 10, bottom 11, and a cover 12 secured to the ends to form a housing or conduit, and at one end a charging conduit or hopper 13 is provided at the top while at the other end at the bottom, a dis charge conduit 14 is located.

At the charging end a flanged collar 15 is keyed to each shaft, and is held against longitudinal movement thereon by a shoulder 16 where the shaft is reduced in dian1- eter. Near the opposite end similar collars Serial No. 671,224.

17 are keyed on the shafts, and between the collars at the ends of the shaft rods 18 are mounted, by having their ends passed therethrough and nuts 19 threaded thereon. Disks 20 are also keyed on the shafts, and through apertures in these disks the rods 18 pass, and as each disk is provided with an annular spacing flange 21 at its inner periphery, they are all securely clamped together in spaced relation by means of the nuts 19 on the ends of the rods.

Strung on the rods 18 at suitable intervals and arranged circumferentially of the shaft are flights 22, and 22, which are mounted to oscillate on the rods and are flights 22 'The object of this is to provide for a slight backward movement of the grain 'unner the influence of the flights 22, as

the pitch of one set of flights is the opposite of the pitch of the other. A stirring and commingling movement is also imparted to the grain by this arrangement, and as the flights on the respective shafts lap one another, the grain will be constantly thrown by one set of flights against the others, so that a more thorough scouring will be effected.

The number of the flights, and their pitch or twist may be varied to suit the circumstances, and the character of the grain which is being treated. The method of mounting them on their shafts may also be varied. For instance, the ends of the rods 18 may be set in notches in the end flanges, and the outer edges of the notches peened over, or they may be received in eyes threaded into the periphery of the collar. Other details of construction may also be changed without departing from the spirit and scope of the invention.

The flights 22 are provided with radial corrugations 23, which will greatly increase their frictional action, and provide for a quicker and more thorough scouring. It will also be noted that the flights are held in positions radial to the shaft by centrifugal action, and that should any jamming of the grain or other obstruction of their path occur they can move inwardly to pass til) thereover, without injury to themselves or to the grain.

The dirt and other matter removed from the grain may be taken off by any suitable means, as, for instance, by the air current of a standard machine, which will take the grain immediately on discharge from the excoriating conveyer, or a special device with fan suction may be employed.

In operation the grain is fed into the upper part of the box or conduit at one end, is propelled therethrough by the flights 22 and discharged through the outlet spout in the bottom at the opposite end, its progress being retarded to a certain extent, and the continuous flow being interrupted and given a reverse movement by the flights 2%, so that it is thoroughly excoriated. The hulls and other impurities are then removed by a suitable blower or other device, and the grain is then ready for the milling operation.

The parts 22 and 22 have been termed flights, as this is the term usually applied to devices designed for similar purposes in the art, but this term is intended as a convenient description, and not as a limitation. The said devices may be termed wings, blades, or vanes, or otherwise designated; and in the appended claims the term flight is intended to include the devices described and shown or equivalent devices.

ll hat I claim is:

'1. The combination of arotatable shaft, flights mounted thereon to rotate therewith and extending radially therefrom in normal position, said flights being individually movably connected with said shaft and being sul'istantially flat with corrugations on one side and disposed in position angular to the plane of their rotation.

2. The combination of a rotatable shaft, flights mounted thereon to rotate therewith and extending ralially therefrom in normal position, said flights being movably connected with said shaft, spaced rods mounted longitudinally of said shaft and arranged circumferentially thereof, upon which the said flights are mounted.

In combination with the parts specified in claim 2 disks secured to the said shaft in spaced relation to one another, through which the said rods pass, the flights being positioned and held against movement longitudinally of the shaft by the said disks.

4-. The combination of a rotatable shaft, flights mounted thereon to rotate therewith and extending radially therefrom in normal position, said flights being movably connected with said shaft, disks mounted on said shaft, said disks being arranged thereon in longitudinal series and provided with means for holding them in spaced relation to one another, and clamping means for securing the said disks and preventing longitudinal movement thereof.

5. In the combination specified in claim l, said clamping means comprising members secured to the shaft at the ends of the series of disks, flanges and rods extending from one flange to the other, one of said. flanges being movable longitudinally of the shaft.

6. In the combination of claim 2 said flights being provided with ribs forming irregular surfaces, the said irregularities being disposed at an angle to their path of rotation.

7. In the combination specified in claim 1, the said co *rugations being radially arranged.

S. In the combination of claim 1, the said movable connection of the flights being such as to permit them to have oscillatory movements in a plane normal to the longitudinal axis of the shaft.

9. In combination with the parts specified in claim 1, a second shaft geared to and rotating with the first shaft in the opposite direction, and similar flights mounted on said second shaft.

10. The combination of a rotatable shaft, flights mounted thereon to rotate therewith and extending radially therefrom in normal position, a second shaft geared to and rotating with the first shaft in the opposite direction, similar flights mounted on said second shaft, the flights having the form of blades disposed at an angle to their path of rotation, the angle of disposition of the blades on one shaft being the reverse of that of the blades on the other shaft.

11. In the combination of claim 10, blades on one shaft lapping blades on the other shaft.

1:2. In the combination of claim the blades onone shaft being less numerous than the blades on the other shaft, and the blades on each shaft having a twist or pitch different from those on the other.

Witness my hand this 19 day of March, 1923, at the city of Salina, in the county of Saline and State of Kansas.

JOHN IV. CORNELIUS.
