FRANK E. rnnnrne'ron, or TOLEDO, ILLINoIs;

LAND-ROLLER.

Application filed May 19, 1909.

10 all whom it may concern:

Be it known that I, FRANK E. PENNING- TON, citizen of the United States, residing at Toledo, in the county of Cumberland and State of Illinois, have invented certain new and useful Improvements in 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 appertains to make and use the same.

My invention relates to new and useful improvements in land rollers and of that class equally adaptable as a clod crusher and my object is to provide a device of this class which will thoroughly pulverize the soil when passed thereover.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1 is a top plan view of the roller complete. Fig. 2 is a sectional view as seen on line 22, Fig. 1. Fig. 3 is a sectional view as seen on line 3, Fig. 2.

Referring to the drawings in which simila r reference numerals designate corresponding parts throughout the several. views, 1 indicates the main frame or reach of my improved roller construction, at the rear end of which is formed a cross bar 2, to the ends of which are attached by means of bolts 3, connecting blocks l. Each of the connecting blocks is provided with a tongue 5, which tongues extend through horizontally disposed slots 6 in auxiliary frame members 7, said tongues also having pins 8 extending from opposite faces thereof, which pins are disposed through vertically disposed slots 9 in the auxiliary frame members, said pins forming a pivot for the auxiliary frame members, as well as limiting the longitudinal movement thereof. The connecting blocks at are also provided with anti-friction rollers 10, said rollers being arranged in pairs and extended above and below the auxiliary frames, the weight of the auxiliaryframes being thus removed from t he'tongues 5 and the friction occasioned by the auxil iary frames reduced to a minimum.

The outer ends of the auxiliary frame members 7 are provided with rearwardly extending arms 11, the free ends of which are provided with bearings 12, in which are mounted shafts 13 of the rollers 14, while Specification of Letters Patent.

Patent-ed Mar. 29, 1910.

Serial No. 496,943.

the inner ends of the auxiliary frame members have rearwardly extending and upwardly curved members 15, which members engage cross plates 16. Dependent from the opposite ends of the cross plates 16 are standards 17, the standards at the inner ends of the cross plates having bearings 18 thereon, which engage the inner ends of the shafts 13, while the standards at the opposite end of the cross plates are preferably formed integral with the bearings 12. The cross plates 16 may also be provided with upwardly extending flanges to form receptacles 19 in which stones or rubbish may be placed when it is desired to remove the same from the field and stones or other objects may be placed in the receptacles to provide additional weight on the rollers.

The peripheries of the rollers 14f are preferably provided with substantially V-shaped corrugations or ribs 20, said ribs being pointed in such manner as to thoroughly pulverize the soil as the rollers pass thereover. The rollers let are normally held in alinement with the cross bar and at right angles to the trend of the frame 1, by means of levers 21, said levers being pivoted to racks 22 and having their lower ends of sutiicicnt length to extend below the frame 1, said levers being secured to the auxiliary frames 7 by means of rods 23 and by providing latch 2% for each of the levers and engaging the same with notches 25 on the 'acks 22, the rollers may be held rigidly in position or by swinging the levers forwardly the rollers may be set at an angle to the cross bar, which is very desirable in extremely rough ground or when cutting stalks.

The forward end of the frame 1 is provided with a socket 26, in which is located a ball 27 carried by the upper end of a standard 28, the lower end of said standard being provided with a clip 29, in which is pivotally secured the squared portion 30 of an axle 31, a bolt 32 passing transversely through the clip and squared portion, thereby permitting the axle 31 to pivot in the clip when the wheels 33 at the ends of the axle engage an obstruction or elevation.

A clevis 3-1 is attached to the standard 28, the upper arm of the clevis extending above the ball 27 and the lower arm below the ball, said clevis extending forwardly from the standard and being provided with an auxiliary clevis 35 to which the usual or any preferred form of double tree is attached, said clevis being provided with openings 36 for adjusting purposes. The clevis 34 is reinforced and made rigid by extending a brace 37 between the clip 29 and outer end of the clevis 3+1, the end of the brace engaging the clevis, being bifurcated and attached thereto by means of a bolt 38, while the lower end of the brace is attached to the bolt 32, said brace forming a rigid connection between the clip and clevis. The frame 1 and cross bar 2 are made rigid by providing suitable brace arms 39 and 40, said brace arms extending from a point adjacent the forward portion of the frame 1 into engagement with the cross bar 2.

It will thus be seen that I have provided a land roller which may be cheaply constructed and at the same time rendered strong and durable and it will also be seen that I have provided means for readily adjusting the parts of the device occasion may require.

that I claim is:

1. A device of the character described, comprising a frame having a cross bar at its inner end, connecting blocks at the ends of said cross bar, auxiliary frame members pivotally and lnovably attached to said blocks, anti-friction devices carried by the blocks adapted to engage the auxiliary frame members, rollers carried by the auxiliary frame members, levers pivoted to said frame and rods connecting the levers to the auxiliary frame, said levers being adapted to control the angle of the rollers.

2. A. device of the character described, comprising a frame having a cross bar at its inner end, connecting blocks at the ends of said cross bar, auxiliary frame-members piv-' otally and movably attached to said blocks, said fran1e-1ne1nbers having longitudinal slots therein, antifriction devices carried by said blocks, said blocks being adjustable by means of said slots, rollers carried by said auxiliary frame-members, levers pivoted to said frame, and rods connecting said levers to said auxiliary frame-members, said levers being adapted to control the angle of said rollers.

3. A device of the character described, comprising a frame having a cross bar at its inner end, connecting blocks at the ends of said cross bars, said blocks having tongues and said auxiliary frame-members having slots therein, said slots receiving said tongues, said tongues also having pins forming pivotal connections for said auxiliary frames, anti-friction devices carried by said blocks adapted to engage said auxiliary framemen'1bers, rollers carried by said aux iliary frame-members, levers pivoted to said frames and rods connecting said levers to the auxiliary frame-members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
