Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
134 words
A soil compressing attachment for travel over the ground comprising a roller rotatably mounted on a horizontal axis, said roller including movably mounted peripheral parts, said parts comprising two spaced apart elongated ground engaging elements mounted on rockable arms, said arms extending substantially parallel to a plane which extends perpendicular to the axis of rotation of said roller, said arms having ends and at least one pivot pin between said ends connected to support means on said roller, said elongated elements extending substantially parallel to one another and said elements being connected to said arms on opposite sides of said pivot pin, said arms and said elements being rockable about an axis defined by said pivot pin and said axis extending in a direction substantially parallel to the axis of rotation of said roller.
Claim 2
Dependent Claim
134 words
A soil compressing attachment for travel over the ground comprising a roller rotatably mounted on a horizontal axis, said roller including movably mounted peripheral parts, said parts comprising two spaced apart elongated ground engaging elements mounted on rockable arms, said arms extending substantially parallel to a plane which extends perpendicular to the axis of rotation of said roller, said arms having ends and at least one pivot pin between said ends connected to support means on said roller, said elongated elements extending substantially parallel to one another and said elements being connected to said arms on opposite sides of said pivot pin, said arms and said elements being rockable about an axis defined by said pivot pin and said axis extending in a direction substantially parallel to the axis of rotation of said roller.
Claim 3
Dependent Claim
51 words
An attachment as claimed in claim 1, wherein said two elements form a pair and there are a plurality of pairs of said elements each of which is pivotable about at least one corresponding pivot pin having an axis that is substantially parallel to the axis of rotation of said roller.
Claim 4
Dependent Claim
31 words
An attachment as claimed in claim 1, wherein said roller includes a central cylinder and the rocking movements of said elements are limited in at least one direction by said cylinder.
Claim 5
Dependent Claim
23 words
An attachment as claimed in claim 3, wherein the rocking movements of said elements are limited in two opposite directions by said cylinder.
Claim 6
Dependent Claim
18 words
An attachment as claimed in claim 1, wherein said elements extend across subtantially the length of said roller.
Claim 7
Dependent Claim
28 words
An attachment as claimed in claim 2, wherein each of said pairs is pivotable about pivot pins on support means that projects radially from said axis of rotation.
Claim 8
Dependent Claim
25 words
An attachment as claimed in claim 2, wherein the corresponding pivot axis of each pair is located midway between the two elements of said pair.
Claim 9
Dependent Claim
28 words
An attachment as claimed in claim 7, wherein said elements of each pair are pivotably supported on said support means at a plurality of locations along their lengths.
Claim 10
Dependent Claim
50 words
An attachment as claimed in claim 1, wherein said roller includes a central cylinder and the periphery of said cylinder comprises three movable pairs of said elements, each of said pairs including at least two elements, said three pairs of elements being spaced apart from one another by even distances.
Claim 11
Dependent Claim
12 words
An attachment as claimed in claim 1, wherein said elements are tubular.
Claim 12
Dependent Claim
15 words
An attachment as claimed in claim 10, wherein said tubular elements are circulAr in cross-section.
Claim 13
Dependent Claim
28 words
An attachment as claimed in claim 1, wherein said arms are pivotally mounted on lug supports and said supports are secured to a central cylinder of said roller.
Claim 14
Dependent Claim
16 words
An attachment as claimed in claim 12, wherein said cylinder is of right circular cylindrical configuration.
Claim 15
Dependent Claim
58 words
An attachment as claimed in claim 1, wherein said roller is a rear-mounted part of a soil cultivating implement having a frame and said implement includes a plurality of soil-working members that are rotatable about their respective upwardly extending shafts, said shafts being supported on said frame in a row that extends transverse to the direction of travel.
Claim 16
Dependent Claim
21 words
An attachment as claimed in claim 14, wherein said roller extends throughout substantially the entire working width of said soil-working members.
Claim 17
Dependent Claim
51 words
An attachment as claimed in claim 15, wherein said roller is pivotally connected to a frame of said soil cultivating implement by adjustable arm means having means for fixing said roller in different vertical positions with respect to said frame, whereby the working depths of the said soil-working members are variable.
Claim 18
Dependent Claim
105 words
A soil compressing attachment for travel over the ground comprising an elongated roller rotatably mounted on a horizontal axis, said roller including a centrally positioned cylinder and a plurality of rockable elongated soil contacting elements pivotably connected to said cylinder around the periphery thereof, said elements being spaced apart and extending parallel to one another and to the axis of rotation of said cylinder, said elements being mounted in pairs and each pair being pivotably mounted for rockable movements about pivot pins, said pivot pins being retained by support means on said cylinder, said pivot pins being located substantially midway between each pair of elements.
Claim 19
Dependent Claim
105 words
A soil compressing attachment for travel over the ground comprising an elongated roller rotatably mounted on a horizontal axis, said roller including a centrally positioned cylinder and a plurality of rockable elongated soil contacting elements pivotably connected to said cylinder around the periphery thereof, said elements being spaced apart and extending parallel to one another and to the axis of rotation of said cylinder, said elements being mounted in pairs and each pair being pivotably mounted for rockable movements about pivot pins, said pivot pins being retained by support means on said cylinder, said pivot pins being located substantially midway between each pair of elements.
