8 Claims.

This invention relates to road disks, and more particularly to an apparatus for disking the surface of a roadway.

An object of this invention is` to produce a road disk in which means are provided for enabling the easy handling and manipulation of road disks vertically with reference to the road surface.

Another object of this invention is to provide a road disk in which means are provided for ad justing the disks and frame of the apparatus relative to the road surface, and which adjustment means includes a spring balanced means for re#- lieving the weight from the adjustment means so that the adjustment may be more accurately and easily accomplished by the operator of the apparatus. Other objects and advantages of this invention it is believed will be apparent frcm the following detailed 'description of a preferred embodiment thereof' as illustrated in the accompanying drawings.

In the drawings:

Figure l is a top plan view of a road disk embodying our invention.

Figure 2 is a side elevation thereof. f

Figure 3 is an enlarged section of the front end adjusting means.

Figure 4 is a sectional view of one of themeans provided for adjusting one side of the frame relative to the road surface at the rear.

Figure 5 is a sectional view taken substantially on the line 5 5 of Figure l.'

. In the preferred embodiment of our invention -I A illustrated in the accompanying drawings, I illustrates a frame to which there are secured by bearing brackets 2 a plurality of gangs of road disks 3. The road disks 3 are mounted in alternate staggered relation in a manner well understood in the art. The frame I is supported at its forward end by means of a caster Wheel 4 and at its rear .end by means of a pair of wheels 5 which are journaled on thespindles 6 of crank axles l.

Means are provided for adjusting the frame with reference to the road surface either so that the road disks 3 may follow the crown of the road or may be adjusted to a horizontal position or may be moved above the road surface to permit the free transportation of the implement without the disks 3 engaging the road surface, which means are herein illustrated as including means (ol. 28o-t central portion rectangular in eifect and is se- Iiv cured to a bracket I). Mounted on the ends of the axle t and the spindle thereof are the road wheels d.

The bracket 9 is vjournaled on a spindle I0,

which spindle is welded to -a plate II. Welded 10 to the upper surface of the plate II is a,` cylinder I2. Secured to the rearward extensionof the plate I I is an adjustment screw I3. Secured to the frame bridge It is a second cylinder I5 which is concentric tc the cylinder I2. The Acylinder I5 l5 is mounted .over the cylinder I2. Interposed between the cylinders I2 and I5 are a plurality of springs I6, I'i and I8, forming a compound spring' structure, the springs being such that they are self-sustaining within thev cylinder I2. For example, the springs I 6 may be right-hand coil, spring I TI, left-hand coil, and spring I8, righthand coil. The springs are supported on the plate il at their lower end and extend upwardly through the cylinder I2 and into the cylinder I5 25 at their upper end where they engage an adjustment plate I0 which is adjustably mounted within the upper portion of the cylinder l5 and held in adjusted position by means of an" adjustment screw "2li which adjusts the initial pressure to 30 which the springs It, II and I 3 are adjusted.- The screw I3 projects upwardly through a guide plate 2l which is secured to the lower end of the cylinder I5 and passes through and is threaded lwithin a bevel gear 22, which meshes with a bevel gearl 23 mounted on the end of the adjustment shaft 25. 'Y

The adjustment shaft 2d extends rearwardly to the rear end of the frame I and is there provided with a wheel 25 for rotation of the shaft 24 to 40 rotate the gear 23 and hence by the direction of rotation to raise or lower the frame I with reference to the forward ground wheels 4. By this construction the weight of the frame I and at` tached parts are relieved from the adjustment means permitting easy rotation of the wheel 25 and an accurate and ne adjustment of the position of the disks 3 with reference to the road surface.

Any suitable or desirable means is provided at the forward end of the implement for moving the implement forward such, for example, as a clevis 26 which is securedy to the forward end of the guide plate `2| and which in turn may be secured to any suitable form of draft tongue 21. Secured to the draft tongue 21 by means of a bracket 28 is a rod 29 which extends forwardly to the tractor or other draft implement to cause the caster wheels 4 to turn with the direction of Vturn of the draft implement. -In order to accomplish this result, a yoke 30 is mounted upon the bar 28 on a roller 3i and extends rearwardly and is clamped adjustment slide 3s is mounted between guides 31 secured to the angles 38 of the frame I. Se-

Icured to the slide,l 36 is an adjustment rod 39Y which extends forwardly and is threaded to a bracket 40 which is securely riveted to the angle 38.

A lock nut 4| is provided for locking the adjusted position of the' slide 36 and thus the initial compression provided in concentrically disposed

springs

42, 43 and 44 mounted'within and between the

cylinders

34 and 35. Secured to crank axles 1 are adjusting arms 45, which arms 45 are pivotally secured to the lower ends of screws 46, which screws 46 are at their upper ends threaded through bevel gears 41. The bevel gears 41 mesh with bevel gears 48 which are secured to the adjustment shafts 49. The adjustment shafts 49 extend rearwardly and are provided with an adjustment handle 50. The, construction of the balancing and supporting means for each of the wheels 5 is the same, so that it is not deemed necessary to describe more than one.

In order to provide for the adjustable mounting of the disk gangs 3 so that these gangs may be adjusted in their angular relation to the surface being worked, the gang rods 60 which carry the disks are journaled in bearings carried by subj frames 6|. The sub-frames 6| are pivotally secured at one end by pivot bolts 62 to the central members of the frame I and at their outer ends are secured by means of bolts 63 to the side members of the frame. 'Ihe bolts 63 are adapted t'o be passed through any one of a plurality of adjustment holes 64 formed in the side frame members.
