Abstract
Abstract A motorless harvester thresher is coupled with a multi-purpose vehicle by means of a coupling rod and a coupling linkage extended between the vehicle and the thresher and pivotally mounted to a lateral side of the vehicle and to a laterial side of the thresher. A driven front axle of the vehicle supporting the front wheels thereof coupled with a non-steerable front axle of the front wheels of the harvester thresher by means of the coupling rod connected to a clutch which can be engaged to or disengaged from the coupling rod so as to ensure the axial alignment of front axes of the vehicle and the machine so as to provide for a stable lateral position of the thresher relative to the vehicle in the traveling movement thereof.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
166 words
In a machine for agricultural works, a combination comprising a multi-purpose vehicle including a driven front axle with front wheels and a rear axle with steerable rear wheels, a motorless agricultural machine coupled to said vehicle and including a non-steerable front axle with front wheels and a rear axle with steerable rear wheels; and means for selectively connecting said agricultural machine to said vehicle in one position in which said agricultural machine is disposed laterally of said vehicle for operation on a field and another position in which said agricultural machine is disposed behind said vehicle for transportation along a road, said connecting means including a connecting rod connectable between said vehicle and said agricultural machine to maintain them in said first position, a coupling linkage pivotally interconnected between said vehicle and said agricultural machine, and means for coaxially aligning the front axle of the agricultural machine with the front axle of the vehicle when the vehicle and the agricultural machine are in said first position.
Claim 2
Dependent Claim
166 words
In a machine for agricultural works, a combination comprising a multi-purpose vehicle including a driven front axle with front wheels and a rear axle with steerable rear wheels, a motorless agricultural machine coupled to said vehicle and including a non-steerable front axle with front wheels and a rear axle with steerable rear wheels; and means for selectively connecting said agricultural machine to said vehicle in one position in which said agricultural machine is disposed laterally of said vehicle for operation on a field and another position in which said agricultural machine is disposed behind said vehicle for transportation along a road, said connecting means including a connecting rod connectable between said vehicle and said agricultural machine to maintain them in said first position, a coupling linkage pivotally interconnected between said vehicle and said agricultural machine, and means for coaxially aligning the front axle of the agricultural machine with the front axle of the vehicle when the vehicle and the agricultural machine are in said first position.
Claim 3
Dependent Claim
72 words
The machine of claim 1, wherein said coupling linkage is adapted to pivot between an operative position in which it is pivotally connected to the agricultural machine at one side thereof and a transporting position in which the coupling linkage is pivotally connected to the agricultural machine at two opposite sides thereof and acts as a pulling means between the vehicle and the agricultural machine when they are in said second position.
Claim 4
Dependent Claim
14 words
The machine of claim 2, wherein said coupling linkage is of a fork-like configuration.
Claim 5
Dependent Claim
36 words
The machine of claim 3, wherein said coupling linkage has at three ends thereof three pivots, one of said pivots being connected to the vehicle and two of said pivots being connected to said agricultural machine.
Claim 6
Dependent Claim
64 words
The machine of claim 4, wherein said vehicle at a rear end thereof is provided with a first cantilever, said one pivot vertically pivotally connected to said first cantilever, the machine being provided with a second and third cantilevers spaced from each other along one side of the agricultural machine, said two pivots being vertically pivotally connected to said second and third cantilevers, respectively.
Claim 7
Dependent Claim
77 words
The machine of claim 5, said agricultural machine being provided with a fourth cantilever positioned at the side of the machine oppositely to said second and third cantilevers, said coupling linkage being adapted to pivot so that after disengaging the one of said two pivots from the third cantilever this one pivot is rotated toward said fourth cantilever and arrested therein to provide repositioning of said agricultural machine relative to said vehicle for transportation along a rod.
Claim 8
Dependent Claim
25 words
The machine of claim 6, wherein the front wheels of the vehicle have approximately the same diameter as the front wheels of the agricultural machine.
Claim 9
Dependent Claim
36 words
The machine of claim 7, said front axle of the vehicle including a first drive shaft, at least one front wheel on the front axle of the agricultural machine being driven from said first drive shaft.
Claim 10
Dependent Claim
19 words
The machine of claim 8, further including a differential gearing on the vehicle, which actuates said first drive shaft.
Claim 11
Dependent Claim
47 words
The machine of claim 9, said aligning means including a clutch connected to the front wheel of the vehicle facing the machine, said first drive shaft extending through said front wheel, and a coupling shaft interconnected between said clutch and the front wheel of the agricultural machine.
Claim 12
Dependent Claim
26 words
The machine of claim 10, wherein said front wheel of the vehicle, connected to the clutch is engageably and disengageably connected to said first drive shaft.
Claim 13
Dependent Claim
33 words
The machine of claim 11, further including a second drive shaft extending through the front wheel of the machine facing the vehicle, said coupling shaft being disengageably connected to said second drive shaft.
Claim 14
Dependent Claim
42 words
The machine of claim 12, the front wheel of the agricultural machine facing the vehicle being loosely mounted on said another drive shafts, the front wheel of the machine facing away from the vehicle being rigidly connected to said another drive shaft.
Claim 15
Dependent Claim
47 words
The machine of claim 8, wherein both front wheels on the front axle of the vehicle are driven so that the front wheel of the vehicle facing the machine is connected with the front wheel of the agricultural machine facing the vehicle immediately through said coupling shaft.
Claim 16
Dependent Claim
20 words
The machine of claim 13, further including a driver cabin arranged in front of said front axle of the vehicle.
Claim 17
Dependent Claim
12 words
The machine of claim 15, wherein said coupling shaft is longitudinally adjustable.
Claim 18
Dependent Claim
