Having thus described my invention, I claim-- 1. In a machine such as described, the oon1- bination with side frames having oppositelyextending spindles cast integrally therewith, of carrying-Wheels having projecting hubs journaied on the spindles extending from. one side of said frames, a rotary sweeper and adjusting-levers for said sweeper ,ionrnaled on the spindles on the opposite side of said frames and driving-gears for the sweeper journaled onthe carrying-wheel hubs adapted to engage and turn with said huhs when the machine travels forward, substantially as specified.

2. In a machine such as described, the combination with side frames and spindles, of carrying-wheels having projecting hubs journaled on said spindles, the inner end of said hubs contacting said frames, a lateral extcn sion forming an annular recess at the other end of said huh, driving-gears for the sweeper having their hubs journaled on the carrying- .adapted to carry the respective ends ol.

wh eel hnosmith one end contacting; c aid side frames and the other end extending into and closing the open side of said recess, and means in said recess adapted to and drive said gears when the machine travels forward, substantially as specified.

3. In a machine such as described, the coinbination with the side fritines, driving gears and pinions, ot' a rotary brnelti and shaft for same on which said pinions are fixed and 1evers pivoted intermediate of their ends to said frames, one end of said levers 'cingg said shaft, racks on said frames and teeth on one side of the other ends of said levers, a spring on the opposite side and a plate adapted in hold said spring under tension against said lever to force said with said rack.

In testimony whereof I have hereunto set my hand this 24th day of February, 1%. i 1903.
