LAND-ROLLER ATTACHMENT.

SPECIFICATION forming part-of Letters Patent No. 475,291, dated May 24, 1892.

Application filed March 19, 1891. Serial No. 385,647. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE S. BURR and JOHN M. CUMMINGS, citizens of the United States, residing at Schochoh, in the county of Logan and State of Kentucky, have invented certain new and useful Improvements in Ground-Roller Attachments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention is fully shown in the accompanying drawings, in which- Figure 1 is a plan of a sectional roller provided with ourattachments. Fig. 2 is an end view of the same, one section of the roller and a portion of the frame being removed. Fig. 3 is a view in the direction of the arrow of Fig. 1,showing a portion of the frame with a certain scraper attached thereto.

In the figures, A is a roller-frame, and Bis ashaft rigidly secured thereto. 0 O are rollersections revolubly mounted upon said shaft, and D is a rigid bar fixed across the frame between the roller-sections and serving as a central support for the shaft. Aseat-support F spans the frame above the sections and bears a seat G and a foot-rest H. A scraper E, preferably a steel plate, is hinged to the rear member of the frame on a line parallel to the shaft B and at a distance from the roller less than the width of the scraper. Upon the foot-rest is pivoted a double crank 1, whose outer arm is adapted to receive pressure from the foot and whose inner arm is connected to the scraper by a rod J ,a bell-crank K, and a rod J, the latter having a hinge union with the scraper-plate. Now if the proper crank is pressed by the foot the scraper is drawn toward the surface of the roller, and any accumulation of damp soil or the like is scraped off and dropped in the rear of the roller. When the crank is released by the foot, the scraper swings away from the roller by its own weight, through evidently aspring may aid or replace the force of gravity.

In order that the edge of the scraper may never come into actual contact with the roller and thereby catch upon its surface, it is out partly across at L, and the end lips thus formed are bent forward and upward to form stops M, Whose ends strike the side members of the frame and thus limit the swinging of the scraper.

From the description it is plain that pressure upon the double crank while the roller makes a complete revolution must remove all adhering matter and that thus a common delay and annoyance are wholly avoided.

What we claim is- The combination, with the frame and roller mounted therein, of the scraper-plate hinged at one edge to the frame, cut partially across near its ends and having the end segments thus formed bent upward to strike the side bars of the frame when the plate is swung toward the roller, substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
