Claim 3
Dependent Claim
26 words
Movable fence to control cattle pasturage, according to claim 1, characterized in that the openings of the fence sections are located above the corresponding pushing means.
Claim 4
Dependent Claim
26 words
Movable fence to control cattle pasturage, according to claim 1, characterized in that the openings of the fence sections are located below the corresponding pushing means.
Claim 5
Dependent Claim
28 words
Movable fence to control cattle pasturage, according to claim 3, characterized in that the openings are formed between the pushing frames and the ground on which it moves.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
45 words
Movable fence to control cattle pasturage, according to claim 1, characterized in that the contiguous ends of said connection means are equipped with transverse displacement adjusting means for preventing the longitudinal axis of each contiguous section from forming an angle smaller than a pre-established value.
Claim 8
Dependent Claim
43 words
Movable fence to control cattle pasturage, according to claim 6, characterized in that said transver displacement adjustment means are constituted by a plurality of bolts located on the fence sections and whose inferior extremes can be driven into the ground to predetermined depths.
Claim 9
Dependent Claim
68 words
A movable fence according to claim 1, characterized in that each said section comprises a rectangular frame and at least two angular members one of the arms of each of which constitutes a sliding shoe, and a fastening rod corresponding to each shoe, the ends of said fastening rod being removably attached to a respective arm of said shoe and said fastening rods being fixed to said frame.
Claim 10
Dependent Claim
53 words
A movable fence for the control of cattle pasturage according to claim 1, wherein said connection means comprise telescoping means pivotally connected at the respective ends thereof to the ends of adjacent fence sections, and tension means for limiting the extension of said telescoping means to control relative displacement of adjacent fence sections.
