PROVISIONAL SPECIFICATION.
Improvements in Agricultural Clod Crushers or Ring Rollers.
I, THOMAS JAMES BAKER, of Eastdon, Starcross, in the County of Devon,
Machinist, Wheelwright, &c., do hereby declare the nature of my invention of
IMPROVEMENTS IN AGRICULTURAL CLOD-CRUSHERS, OR RING ROLLERS," to be as
follows:-
"
My invention has for its objects―
To steady the rings and prevent them spreading or swaying from side to side.
For this purpose, I use an elongated bearing for each ring by forming on it a "boss"
or "sleeve," and by fitting one set on the axle and the remainder on the first set,
each ring being thus provided with a bearing much longer than usual, while retaining
the power to turn independently of the others. At each end of the axle I also fix
rigidly on the axle a stop" or guide" carrying special friction rollers, which also
tend to prevent the rings spreading or swaying froin side to side, but are so fixed as
to allow the rings to turn with little or no friction. This "stop or "guide" is also
provided with a sleeve" which answers the double purpose of steadying the " 'stop
or "guide" and of lining the axle, thus relieving it from wear.

COMPLETE SPECIFICATION.
Improvements in Agricultural Clod Crushers or Ring Rollers.
1, THOMAS JAMES BAKER, of Eastdon, Starcross, in the County of Devon,
Machinist, Wheelwright &c. 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 has for its object to steady the rings of a clod crusher or ring roller,
and prevent them from swaying from side to side or spreading, thereby ensuring less
friction and greater durability.
To do this I use an elongated bearing for each ring, by forming on it a "boss" or
"sleeve" and by fitting one set on the axle, and the remainder on the "sleeves" or
"bosses" of the first set, each ring being thus provided with a bearing nearly double
(in some cases, quite double) the length obtainable when each ring is fitted on the
axle thereby ensuring greater steadiness and prolonged wear, while each ring retains
its power to turn independently of the others.
At each end of the axle, I fix rigidly on the axle a "stop" or "guide," carrying
special friction rollers, which also tend to prevent the rings spreading or swaying
from side to side, but are so fixed as to allow the rings to turn with little or no
friction, according to whether the clod crusher is moving in a curvilinear or straight
line. These "stops" or "guides" are also provided with "bosses"
"sleeves'
which answer the double purpose of strengthening & steadying them, and of lining
the ends of the axle, thus relieving the latter of wear.

Fig. 1 shows a part back elevation, and part longitudinal section, and Fig. 2 the
side elevation. The rings marked a are made to fit on the axle, on which they are
able to turn with ease, independently of each other; they are all provided with
bosses or sleeves of the maximum length. The ring 6 is rigidly fixed to the
axle. The rings marked c are also provided with "bosses" or "sleeves," but, instead
of being fitted on the axle, are fitted on the "bosses
marked a and b thus obtaining the elongated bearings.

which steadies and strengthens the stop, and relieves the end of the axle of wear.
These "
stops or guides are fixed to the axle and are provided with special
friction rollers which tend to diminish friction when the clod crusher is moving in a
curvilinear line by revolving, against the ring adjacent to each, on the pins g. One
of these pins in each stop is made sufficiently long to fix the stop to the axle ;
the remainder need only be tapped into the inner part of the stop for a short
distance.
When the clod crusher or roller is moved in a straight line the axle, rings, and
stops carrying the friction rollers all revolve together, the only friction being between
the "bosses or "sleeves" of the stops and the "ends" of the frame, where means for
lubrication are provided.
When the clod crusher is moving in a curvilinear line the rings on the outer side of
the curve revolve at a greater rate than those on the inner side of the curve (these
latter may sometimes revolve in the opposite direction) and the axle, revolving with
the central ring, carries with it the stops, whose friction rollers then revolve against
the adjacent ring and allow the different rings to revolve at their various degrees of
velocity with a minimum amount of friction and without spreading or swaying from
side to side.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be applied, I declare that what I
claim is
1. The use of elongated bearings for the rings, of a "clod crusher" or "ring
roller" to prevent them leaning on each other, or swaying from side to side, by
forming on them "bosses" or sleeves and by so arranging them as to use the
"sleeves" or bosses of one set as an axle for the remainder, substantially as herein
described.
2. The use of a stop, at each end of the axle, carrying special friction rollers, which
tend to keep the rings from spreading or swaying, and at the same time allow them
to turn independently of each other, with a minimum amount of friction, substantially
as herein described.
