Construction of une rouer as well as bus connections betwe

In these figures I havo represented the frame-work as of rectangular shape at A,
and this encloses the rollers B, B, being connected thereto as hereinafter more
particularly described.. I have shown the rollers as two in number but I do not
limit myself in this connection. Each is composed of heads having suitable spokes
with a flanged periphery, the flanges being provided with a series of openings and
these heads are connected by the working periphery of the wheel which is made up
of a series of castings having a central projection a, and a flanged base h. The
flanges at each end are provided with recesses preferably semi-circular and through
the circular opening formed by placing a second casting alongside a headed bolt is.
passed, the head thereof bearing on the flanges while the screw threaded end is
secured by means of a nut after the end is passed through one of the openings in
the flanged periphery of the head.
The periphery of the roller is made up by a continuous series of these castings
held by the beaded bolts as described. In case the roller should be of an unusual
width it may be found uecessary to have an intermediate head arranged centrally
of the two outer heads. The projecting portions of the periphery serve to thoroughly
pulverize the earth and crush the clogs and to put the land into condition for
seeding. Each roller is mounted upon a shaft to which the roller is fixed, and each
end of the shaft is provided with a ball formation which is adapted to sockets in
pivoted bars secured to the frame. At the outer end this bar is shown at c, having
its free end provided with the sockets d, and pivoted at its opposite end to the
underside of the frame being hold by a clip d', adjustably secured by a bolt passing
through the slotted portion of said clip to the under side of the frame, said clip
carrying the pivot of the bar c. It will thus be seen that the roller is not only
free to turn with its shaft by reason of the ball and socket connection at the outer
end but by reason of the pivoted connection between the frame and the bar at each
outer end, the frame is allowed horizontal end wise movement independently of the
rollers. The inner end of each of the roller shafts is also as has been described,
provided with a ball formation fitting a socket in the bars e, f, the bar e, extending
to the rear of the frame where it has pivoted connection with a link 1, so as to swing
horizontally and this link is pivoted to a bracket 2, depending from the frame so as
to have vertical movement. The bar f, extends to the front of the frame and has
a pivoted connection therewith through a link so as to permit of horizontal and
vertical movement also. A bracing arch extends between the front and rear parts
of the frame as at D, at a point intermediate of the two rollers.
It will thus be seen that the frame has independent horizontal movement and also
