Assembly for concave fitted with material other than grain (MOG) limiting devices
A MOG limiting device, herein described as a MOG limiter, approximates a portion of the curvilinear length of a concave. The MOG limiting device can include a connection point near the middle of a concave, slightly offset from center. A bolt, washer and nut assembly protrudes downwardly from the underside of the concave. Two assemblies are positioned in the middle of each side of the concave. The assemblies cooperate with a mounting plate on the MOG limiters to form an upper concave connection and a lower concave connection in each half of the concave. In the cross frame, insert slots are positioned to receive a hinge point located at the end of each arced member making up the frame (rail supports). The hinge points are slidably inserted into the opening and then rotated upwardly to be positioned adjacent to and in conformity with the curvature of the underside of the concave with the connection assemblies holding the MOG limiter in place.
1. An assembly for a concave fitted with material other than grain (MOG) limiting devices, said assembly comprising:
a series of MOG limiters each comprising:
a frame comprising two arced members;
a plurality of inserts extending between the two arced members; and
an upper concave connection and a lower concave connection; and
wherein the lower concave connection attaches at least one MOG limiter of the series of MOG limiters to the concave near a midpoint of arced members of the concave;
where the two arced members of the MOG limiter comprises prongs at the lower concave connection insertable into a center catch extending between the arced members of the concave.
2. The assembly of claim 1 wherein the upper concave connection and the lower concave connection are each established by a latch assembly.
3. The assembly of claim 2 wherein the latch assembly employs a spring tensioning handle which upon closing draws the MOG limiter up into a position on the underside of the concave.
4. The assembly of claim 3 wherein the latch assembly includes a J-hook.
5. The assembly of claim 4 wherein the position on the underside of the concave is a mounting plate on the concave, wherein the mounting plate further comprises a threaded post extending downwardly therefrom.
6. The assembly of claim 5 wherein the J-hook further comprises a straight, male-threaded end and a female-threaded sleeve directly attached to the handle that allows attachment among the J-hook and the threaded sleeve.
7. The assembly of claim 6 wherein the handle comprises a beam or rigid rod that pivots about a point near the threaded sleeve.
8. The assembly of claim 1 wherein the concave is (i) a ⅝ inch round bar concave having a ¾ inch gap between round crossbars or (ii) a ⅝ inch round bar concave having a ⅞ inch gap between round crossbars.
9. The assembly of claim 1 further comprising a pivot joint to rotatably affix an end of the limiter at or near a center point of the concave, wherein the pivot joint is an insertable T-slot pivot assembly to affix and retain the one end of the MOG limiter at or near the center point of the concave.
10. The assembly of claim 1 wherein the MOG limiter utilizes at least one threaded locking mechanism to fasten the end of the MOG limiter to the end of the concave and to retain the MOG limiter against the curvature of the concave, wherein the threaded locking mechanism of the MOG limiter is pulled or pushed by turning a retention housing and/or one or more retention nuts, thereby moving the MOG limiter laterally as it is positioned on the concave.
11. The assembly of claim 1 further comprising one or more cover plates, wherein each cover plate comprises a curvilinear plate positioned between two parallel arcuate rails of the concave.
12. The assembly of claim 11 wherein each one of the one or more cover plates do not span an entire length of said arcuate rails.
13. The assembly of claim 11 wherein the one or more cover plates comprise two cover plates that in combination are positioned and oriented to span the entire length of said arcuate rails.
14. The assembly of claim 11 wherein the one or more cover plates comprise a plurality of parallelly oriented arced supports.
15. The assembly of claim 14 wherein the one or more cover plates comprise at least one bridge support that covers a horizontal distance between one of the arced supports to the other.
16. The assembly of claim 11 wherein the one or more cover plates comprise a mounting plate.
17. The assembly of claim 1 wherein round bars of the concave are spaced substantially equidistantly from one another.
18. The assembly of claim 1 wherein rub bars of the concave and round bars of a concave alternate, and further wherein the rub bars and the round bars are spaced substantially equidistantly from one another.
19. The assembly of claim 1 wherein rub bars are included in triplets and remaining bars are round bars, and further wherein the rub bars and the round bars are spaced substantially equidistantly from one another.
20. The assembly of claim 1 wherein rub bars are included every third bar and remaining bars are round bars, and further wherein the rub bars and the round bars are spaced substantially equidistantly from one another.
