page_text: I, WILLIAM JONES, of Caffins Heanton, Lynton, in the County of Devon, Farmer,
do hereby declare the nature of this invention to be as follows
My invention relates to land-rollers or clod-crushers of that class which is composed
essentially of a number of wheels, rings, or sections placed side by side upon a central
axle.
In the use of a roller of this kind it is found that, owing to the wear of the central
holes in the sections and to their short bearing surfaces, the rings or sectious gradually
assume a position inclined to the axle, especially so, when working on the least hill-
side land, thereby increasing the draught of the implement by reason of the excessive
friction.
My invention has for its object to prevent the wheels, rings, or sections of a land-
roller or clod-crusher from falling over or becoming inclined to the axle, and to this
end it consists essentially in arranging the sections in groups in the novel manner
hereinafter described.
The groups at the two ends of the roller preferably consist of three sections each,
the outermost section of all having an elongated boss which fits upon the central axle
and forms a long bearing surface. The other two sections of the group are mounted
upon the said boss and are free to rotate thereon:
Between the two end groups I place a series of other groups of sections according
to the width of the roller. Each of these groups preferably consists of five sections,
the central section being provided upon both sides with an elongated boss so that it
can carry two other sections upon each side of the central section of the group. It
will thus be understood that each group has a broad bearing upon the axle.
Between the series of groups I can place one or more sections on the central axle
according to width of roller.

page_text: I, WILLIAM JONES, of Caffins Heanton, Lynton, in the county of Devon, Farmer,
do hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in. and by the following
statement:
My invention relates to land-rollers or clod-crushers of that class which is composed
essentially of a number of wheels, rings, or sections placed side by side upon a central
axle.
In the use of a roller of this kind it is found that, owing to the wear of the central
holes in the sections and to their short bearing surfaces, the rings or sections gradually
assume a position inclined to the axle, especially when working on the least hill-side
land, thereby increasing the draught of the implement by reason of the excessive
friction.
My invention has for its object to prevent the wheels, rings, or sections of a land-
roller or clod-crusher from falling over or becoming inclined to the axle, and to this
end it consists essentially in arranging the sections in groups in the novel manner
hereinafter described.
In the accompanying drawing,
Figure 1 is a sectional view showing three groups of sections arranged according to
my invention.
Figures 2 and 3 are an elevation and vertical section respectively of one of the
sections and,
Figure 4 is a sectional view of another section.
Figures 5 and 6, 7 and 8, and 9 and 10, are respectively sectional views and
elevations of other sections.
According to my said invention the groups at the two ends of the roller preferably
each consist of three sections a, a, a². The outermost section of each of these groups
has an elongated boss b upon one side which boss fits upon the central axle and
forms a long bearing surface. The other two sections a¹, a² of the group are mounted
upon the said boss and are free to rotate thereon. As shown, the sections a¹ are much
narrower than the sections a² for the purpose of cutting fine lines on the soil but this
is inmaterial provided the boss b is of sufficient length.
Between the two end groups I place a series of other groups of sections according
to the width of the roller. Each of these groups preferably consists of five sections
the only difference between it and the end sections being that the central section c of
each group is provided with an elongated boss c¹ projecting from both its sides so that
it can carry two sections.a1, a2 upon each side of the central section c. It will thus
be understood that each group has a broad bearing upon the axle while every section
revolves independently of the others.
Between the series of groups I can place one or more alternately broad and narrow
sections d on the central axle to suit any special width of roller required.

page_text: Although in the drawing I have only shown three groups of sections it is to be
understood that any other desirable number of groups may be employed according to
the width of roller required.
I wish it understood that I do not limit my improvements to rollers having sections
of the kind shown, as it is obvious that they are equally applicable to rollers the
sections of which are plain or toothed or otherwise formed on the peripheries.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1 A land-roller or clod-crusher comprising a number of groups of wheels, rings or
sections, one section of each group having an elongated boss or bosses upon which
the other sections of the group are mounted, substantially as described.
2. A land-roller or clod-crusher having a series of groups of wheels, rings or
sections, substantially as herein before described and illustrated in the accompanying
drawing.
3. The manufacture and use of wheels, rings or sections for land-rollers or clod-
crushers adapted to be arranged in groups, substantially as hereinbefore described and
illustrated in the accompanying drawing.
