Abstract
Abstract A harvester-thresher has a frame adapted to be pulled along the ground and formed with a forwardly-opening slot which is flanked by a pair of flailing elements that are displaced back and forth relative to this slot without cutting or pulling up this crop in order to thresh grain or the like from a crop passing upwardly through the slot. The flailing elements can be a pair of vibratorily reciprocal elements operated by a crank arrangement. It is also possible to use a pair of rotatable supports which each carry a pair of polygonal-section rollers that are orbited next to the slot and are themselves rotated about their own axes to flail the grain off the crops. The two assemblies are interconnected by a pair of gears and the individual rollers are themselves rotated by means of a V-belt or an internal gear connected to the ends of these rollers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
A harvesting machine for a grain-carrying standing crop, said machine comprising: a frame adapted to be displaced along the ground in a horizontal transport direction and formed with an upwardly and rearwardly inclined platform with a forwardly opening slot; a pair of flailing elements on said frame to either side of said slot; drive means on said frame for displacing said elements horizontally back and forth relative to said slot for threshing grain from crop projecting upwardly through said slot; an upwardly and rearwardly extending collector conveyor on said frame including at least one belt on said frame below said slot for catching grain threshed from said crop; and a cropper for said grain below said platform at the rear thereof for receiving grain from said conveyor.
Claim 2
Dependent Claim
127 words
A harvesting machine for a grain-carrying standing crop, said machine comprising: a frame adapted to be displaced along the ground in a horizontal transport direction and formed with an upwardly and rearwardly inclined platform with a forwardly opening slot; a pair of flailing elements on said frame to either side of said slot; drive means on said frame for displacing said elements horizontally back and forth relative to said slot for threshing grain from crop projecting upwardly through said slot; an upwardly and rearwardly extending collector conveyor on said frame including at least one belt on said frame below said slot for catching grain threshed from said crop; and a cropper for said grain below said platform at the rear thereof for receiving grain from said conveyor.
Claim 3
Dependent Claim
65 words
The machine defined in claim 1 wherein said drive means includes a rotatable disk carried on said frame, an eccentric pin on said disk, and a link connecting said pin to said disk, and a link connecting said pin to said flailing elements, said elements being slidable on said frame transversely to said slot whereby rotation of said disk reciprocates said elements on said frame.
Claim 4
Dependent Claim
39 words
The machine defined in claim 2 wherein said flailing elements are parallel to and flank said slot, said drive means including guides at the front end of said elements for displacement of said front ends orthogonally to said slot.
Claim 5
Dependent Claim
48 words
The machine defined in claim 1 wherein said drive means includes a pair of supports pivotal about respective axes parallel to and flanking said slot, said elements each being at least one elongated roller carried on a respective support and orbital about and parallel to a respective axis.
Claim 6
Dependent Claim
28 words
The machine defined in claim 4 wherein said drive means includes means for rotating said elements about their own axes as said elements orbit about the support axis.
Claim 7
Dependent Claim
26 words
The machine defined in claim 4 wherein said means for rotating includes a pair of belts each spanned over a respective roller and a respective support.
Claim 8
Dependent Claim
32 words
The machine defined in claim 4 wherein said means for rotating includes a pinion carried on each roller and a gear carried on the respective support and meshing with the respective pinion.
Claim 9
Dependent Claim
13 words
The machine defined in claim 7 wherein said gear is an internal gear.
Claim 10
Dependent Claim
29 words
The machine defined in claim 4 wherein each support is a rod and carries a pair of such flailing elements parallel to and diametrically opposed across the respective axis.
Claim 11
Dependent Claim
23 words
The machine defined in claim 9 wherein said drive means includes a pair of meshing gear wheels each carried on a respective support.
