Abstract
Abstract The invention relates to a device for collecting and lifting groups of straw bales comprising a frame and members arranged beneath said frame for gripping the straw bales, said gripping members being formed by rods, spaced apart from and parallel to one another and adapted to move towards and away from one another in a direction transverse of the rods, in a manner such that straw bales dispersed on the field can be picked up one by one and be collected into groups for further transport.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
In a vehicle for picking up bales, a device for collecting groups of bales, comprising a horizontal frame and gripping members depending from said frame for gripping the bales, the gripping members being formed by a plurality of generally horizontally rod-shaped elements disposed in spaced, parallel relation to one another and the members being movable towards and away from one another in a direction transverse of the direction of the rods, means for driving at least one outermost gripping member in said transverse direction, and at least that intermediate gripping member adjacent the movable outermost member being pivotally mounted on the frame so as to be swingable inwardly and stop means for limiting outward return movement of said intermediate gripping member to a substantially vertical position.
Claim 2
Dependent Claim
126 words
In a vehicle for picking up bales, a device for collecting groups of bales, comprising a horizontal frame and gripping members depending from said frame for gripping the bales, the gripping members being formed by a plurality of generally horizontally rod-shaped elements disposed in spaced, parallel relation to one another and the members being movable towards and away from one another in a direction transverse of the direction of the rods, means for driving at least one outermost gripping member in said transverse direction, and at least that intermediate gripping member adjacent the movable outermost member being pivotally mounted on the frame so as to be swingable inwardly and stop means for limiting outward return movement of said intermediate gripping member to a substantially vertical position.
Claim 3
Dependent Claim
40 words
In a vehicle as claimed in claim 1, wherein a central gripping member is rigidly secured to said frame at the center thereof, and two outermost gripping members are arranged so as to be movable inwardly in a transvers direction.
Claim 4
Dependent Claim
39 words
In a vehicle as claimed in claim 2, wherein the foremost parts of said rod-shaped elements are bent outwardly, the angle of bending being larger than the greater distance of said rod-shaped elements from the center of said frame.
Claim 5
Dependent Claim
19 words
In a vehicle as claimed in claim 2, wherein said intermediate gripping member is releasably coupled with the frame.
Claim 6
Dependent Claim
25 words
