LAND-ROLLER.

Specification of Letters Patent.

Patented April 20, 1909.

. Application filed July 6, 1908. ScrialNo. 442,045.

Land-Rollers; and I 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 appertainsto make and use the same.

My invention relates to improvements in land rollers, and more particularly to reversible scrapers for reversible land rollers, and its object is to provide a reversible scraper to engage the roller and remove adhering material therefrom when the roller revolves in either direction, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims.

The device consists essentially of a flat plate journaled in the frame near the roller adapted to alternately engage the respective edges of the plate with the surface of the roller, and a weighted lever adjustably attached to the late and adapted to alternately and yiel ingly maintain contact of the respective edges of the plate with the roller, and in various details of construction and arrangement, as will more fully appear by reference to the accompanying drawings in which;

Figure 1 shows a portion of a roller with my device attached; Fig. 2 a detail partially in vertical section, and adjusted with the lower edge of the plate in contact with the roller; Fig. 3 the same adjusted out of actionand with the roller omitted; and Fig. 4 an elevation at right angles to Fig. 3.

Like numbers refer to like parts in all of the figures.

1 represents the roller and 2 the frame of a land roller such as shown in my Patent No. 894,430, granted July 28, 1908, on land rollers.

3 is a rock shaft journaled in the frame near the outer surface of the roller and spaced apart therefrom, said shaft having a flattened middle portion to which is attached a flat steel plate 4 having its respective edges projecting above and below the shaft a suitable distance to alternately engage the surface of the roller as the shaft is oscillated about its axis To shift this shaft and yieldingly hold the edge of the plate in contact with the roller, I provide an upwardly projecting arm 5 fixed on the shaft and carrying a slotted segment 6. Pivoted to this arm near the shaft 3 is a lever 7 extending through the slot of the segment and traversing the same, on the upper end of which lever is adjustably mounted a weight 8;

To hold the arm 5 in vertical position with the plate 4 vertical and out of contact with the roller, I provide a sliding bolt 9 mounted on the frame 2 and adapted to engage an opening 10 in the arm, and thus lock the same in vertical position.

In order to engage the l{plate 4 at pro er angle for scraping the su ace of the ro er, the shaft 3 has but a limited movement about its axis and is close to the roller. The slotted segment 6 afiords a greater angular movement to the lever 7 than has the shaft and plate, whereby the lever shifts to a greater distance from the vertical position than does the arm. The weight is thus rendered more effective, and will not unintentionally shift from side to side.

When the roller is reversed in operation, the position of the weight and lever 7 is re versed in the segment and this change re versesthe plate 4 with its other edge in contact with the roller, and thus properly adjusts it for the reversed movement of the roller. When locked in vertical position by the bolt 9, the plate is out of contact with the roller and inoperative.

What I claim is 1. A land roller, comprising a roller, 2. frame in which the roller is rotative, a plate journaled in the frame and ada ted to alternately engage its respective e ges with the surface of the roller, and a weight connected to the plate and shiftable to opposite sides of the vertical plane of the pivots of the plates.

2. A land roller, comprising a roller, a frame in which the roller is rotative, a plate journaled in the frame and ada ted to alternately engage its respective e ges with the roller, an upwardly projecting lever connected to the plate and shiftable to oppositely inclined positions, and a weight attached to the lever.

3. A land roller, comprising a roller, 2. frame in which the roller is rotative, a rock shaft journaled in the frame and extending near the surface of the roller and spaced apart therefrom, a plate attached to the rock shaft and alternately engaging the roller at its respective edges, an arm fixed on the shaft and extending u ward there from, a segment on the arm, a ever pivoted near the shaft and traversing the segment, and a weight attached to the lever.

4. A land roller, comprising a roller, a frame in which the roller is rotative, a rock shaft journaled in the frame, a plate attached to the shaft and alternately engaging the roller at its respective edges, an arm fixed on the shaft and extending upward therefrom, a bolt engaging the arm to lock the same in vertical position, a segment on the arm, a lever pivoted on the arm near the shaft and traversing the segment, and a weight attached to the lever.

in a land roller, the combination of a roller, a frame in which the roller is wrotati've,

.a rock shaft journaled in the frame and h aving a flattened portion opposite the roller, a

fiat plate attached to said portion and alterto the arm near the shaft and traversing the slot in the segment, a weight 011 the lever, and a slidable bolt on the frame and engaging the opening in the arm to lock the arm in vertical position.

In testimony whereof I affix my signature in presence of two witnesses.
