SPADER ROLLER.

Application fiIed March 10, 1928. Serial No. 260,604.

The object of my invention is to provide a spader roller of simple, durable, and comparatively inexpensive construction.

A further object of my invention is to provide a spader roller of the type herein disclosed in which a plurality of roller disks are rotatably mounted on a shaft whereby they are independently rotatable on the shaft for preventing them from collecting mud and to allow easy turning of the roller around corners, these roller disks being provided with diagonal projections on their peripheries.

Still a further object is to provide in connection with the roller a suitable frame work for pulling the roller across ground which has been plowed for the pur ose of pulverizing the clods and getting t e ground into better shape for planting.

Still a further object is to provide a second roller in connection with the roller already mentioned with the diagonal projections on the second roller slanting in a direction opposite those on the other one for the purpose of forming depressions in the ground over which the device travels which are broken up into crosses to prevent the formation of small ditches down which rain might wash the soil away.

Still a further object is to provide half the disks on one shaft with the projections in a direction opposite to those on the other half so that the device will not have'a tendency to run toward one side but will maintain a straight course behind the tractor or team be.- ing used as motive power for the device.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more full set forth, pointed out in my claims and illustrated in the accompanying drawings. Although the invention is susceptible of a variety of embodiments, it is unnecessary to fully describe and illustrate more than one in order to give a full understanding of the invention both from its structural and functional standpoints. Accordingly, I have illustrated a preferred and desirable embodiment of the invention in the accompanying drawings in which:

Figure 1 is a plan view of a land roller embodying my invention and illustratin the two rollers journaled on a suitable rame work.

Figure 2 is a side elevation of the. same.

Figure 3 is a perspective view of one of the roller disks a plurality of which are used to form the roller.

. secured to the shaft on which it is mounted.

On the accompanying drawings I have used the reference character A to indicate generally one of the rollers. The other roller is indicated by the reference character B. The rollers A and B are mounted on

shafts

10 and 12 the ends of which are journaled in bearings 14 and 16.

A framework C is provided to which the bearings 14 and 16 are secured. The frame C comprises two symmetrically similar members l8 and 20 which terminate in forwardly projecting arms 22 spaced from each other. A pivot plate 24 is pivoted by means of the bolt 26 to the arms 22. A tongue or draw bar 28 is secured to the pivoted plate 24. The frame work C and the draw bar 28 merely illustrate one embodiment of a suitable frame work for my device and it is obvious that a frame work of any suitable character to suit the conditions encountered may be provided to be substituted for the frame C. For instance in a horse drawn device. it would be desirable to have supporting means for a seat for the driver.

The rollers A and B comprise a series of

disks

30 and 32. Each of these disks consists of a rim 34 having projections 36 extending therefrom. Each disk also has a hub 38 to fit over the

respective shafts

10 and 12 whereby the disks may freely rotate thereon. The projections 36 on the disks 30 slant in one direction and those on the disks 32 slant in an opposite direction.

It will be noted that half of each roller A and B is provided with disks 32 for the purpose of preventing a tendency of the device to run sideways when being drawn across the ground.

It will be further noted that disks 30 are used on the roller B directly behind the disks 32 on the roller A. This results in a row of depressions 42 (see Figure 1), being formed by the roller disk 32 as shown in dotted lines and depressions 44 being formed over the depressions 42 by the roller disk 30. This prevents the formation of ditches and obviates the result of small water ways being formed so that when it rains thesoil will be washed away.

The ground over which the roller travels is pulverized and broken up into a series of crosses which prevent any tendency ofditches depressions which would have a tendency to form ditches. From the foregoing description the ad vantages of my device will be readily apparent.

Some changes may bemade in the'eonstruction and arrangementof the-various parts of my invention, Without departing from the real spirit and purpose of my invention,- and it is my intention to cover by my claims any modified forms of structure or useofmechanical equivalents,- which may be reasonably included Within their scope.

I claim as my invention:

1. A spader roller of the class describe'c comprising a; frame, a shaft thereon, a plurality of roller disks rotatable on said shaft diagonal proj ections-on the periphery of each disk, a second shaft behind the firstone, a-plurality of disksrotatable on said 'seoond shaft,

diagonal roj'eotions} on" said second mentioned disks inclined in direction opposite to the ones on the disks on the first mentioned shaft. V y

2. A spader roller of the class described, comp-rising a frame, a shaft thereon, a pluralityof roller disks rotatable on said shaft, diagonal pr-ojections on the periphery of each disk, a second shaft behind the first one, a plurality of disks rotatable onsaid second shaft, diagonal projections on said second mentioned disks inclined in a direction opposite to the ones on the dfiskson the first mentione d sha ft, the proj ecti'onsonadjacent disks being free to assume staggered relation with respect to each other.

8. A spader roller ofrthe c-l'ass" described comprising a frame, a shaft thereon, a plurality of roller disksrotatable on said shaft, diagonal projections on the periphery" of'ewch disk, a secondi shaft behind the first one, a plurality of disks rotatable on said second shaft, diagonal projections onsaid second mentioned disks-inclined in a: direction opposite to the ones on thedisl'cs on the first mentionedlshaf-t,the projection's on halfi thed'isks being of opposite inclination.
