4 Claims.
This invention relates to land rollers of the power operated type, the primary object of the invention being to provide a roller including a plurality of roller members, means being provided for operating the rollers to raise the rollers simultaneously facilitating the guiding or turning of the device.
Another object of the invention is the provision of means for mounting the rollers whereby reciprocating movement of rack bars, will operate to raise and lower the rollers.
A further object of the invention is to provide a land roller including a power operated spiked cylinder operating in advance of the rollers of the machine, thereby conditioning the road surface for the rolling operation and insuring a smooth and even surface.
A still further object of the invention is the provision of a machine of this character having -means for adjusting the spiked roller vertically,
regulating the depth of operation of the spiked roller and adapting the machine for use in conditioning various types of roads.
With the foregoing and other objects in view,
which will appear as the description proceeds, the
invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, Without departing from the spirit of the invention.
Referring to the drawings:
Figure 1 is a plan view of a device constructed in accordance with the invention.
Figure 2 is a side elevational view thereof. Figure 3 is an enlarged detail view showing the vertically movable rollers as spaced from the supporting. surface.
Figure 4 is a fragmental sectional view taken on line 4--4 of Figure 1. v
Figure 5 is a sectional view taken on line 5-5 of Figure 1.

line
Figure 12 is a fragmental detail View illustrating the elongated openings in the side bars of the frame of the roller, to permit of swinging movement of the vertical power shafts.
Referring to the drawings in detail, the device comprises a rectangular frame 5 constructed of suitable channel bar material and provided with truss rods 6, for bracing the frame.
The rollers 12, are of diameters equal to the diameters of the roller 9, and are provided with shafts 13 that are disposed in the bearings 14. These bearings 14 are mounted for rotary movement, and as shown are provided with teeth 15.
The shafts 13 that extend into the bearings 14, are eccentrically mounted within the bearings .14, so that the rollers 12 supported thereby, may be raised and lowered at the will of the operator. The bearings 14 operate in bearing housings 16, that are secured in openings formed in the side bars of the frame 5. Mounted above the bearings 14, are arms 17 on which the rollers 18 are mounted, the rollers being provided with spaced flanges, between which the bars 19 operate, holding the bars 19 against lateral movement.
These bars 19 constitute the actuatingbars of the device, and are formed with teeth 20 meshing with the teeth 15 of the bearings 14, and since the shafts 13 are eccentrically mounted, it will be seen that the rollers 12 will be raised and lowered, when the bars 19 are reciprocated.
The reference character designates pivoted scrapers that are supported by the frame of the device, and are urged into engagement with the rollers by means of the coiled springs 26, to the end that the rollers are maintained free of foreign matter.
The side bars of the frame are securely braced. by the brace rods 27 that have their ends connected to the side bars of the frame, thereby lending rigidity to the frame and adapting the device for use on uneven surfaces.
It might be further stated that grease cups such as shown at 28 are used in connection with the bearings, for supplying grease to the bearings and shafts.
Supported at the forward end of the land roller, is a hitch 29, to which a suitable power device not shown, may be connected for moving the land roller over the surface under treatment.
In the modified form of the invention as shown by sheets 3 and 4 of the drawings, the roller is of the self-propelled type and comprises a frame embodying side bars 30 and end bars 31, which bars are of the channel construction, the side bars 30 being supplied with truss rods 32 for adding strength to the structure.
Mounted within the frame is a central roller 33 and a plurality of vertically movable rollers 34, mounted on opposite sides of the central roller 33.
' These rollers 34 are mounted in bearings that in turn are eccentrically constructed, the bearings having teeth to be engaged by teeth of the controlling bars 35, the controlling bars 35 being in turn operated by the shaft 36 that is rotated by the hand wheels 37, the shaft 36 transmitting movement to the bars 35, through the gears 38 that mesh with teeth on the bars 35. Thus it will be seen that due to this construction, the rollers 34 may be raised and lowered by the operator, to
the end that the roller may be turned on the ,engine being supplied with a shaft 40.
end of the shaft 40, is a coupling 41 that accommodates one end of the shaft 42 in such a way that the shaft 42 may slide with respect to the shaft 40, for purposes to be hereinafter more fully described.
The shaft 42 extends forwardly where it connects with the shaft 43, through the universal coupling 44, the shaft 43 being mounted in a bearing at the upper end of the support 45. A horizontal shaft 46 is also supported on the frame and has a pinion 47 meshing with the pinion 48 of the shaft 43 so that rotary movement of the shaft 42 is imparted to the shaft 46.
At one end of the shaft 46 is a pinion 49 that meshes with the pinion 56 disposed at the upper end of the vertical shaft 51 so that the shaft 51 is also rotated, through the pinions and shafts.
As clearly shown, the shaft 51 extends through elongated openings 52 formed in the side bars of the frame, the shaft 51 carrying a pinion 53 at its lower end, that meshes with the gear 54 carried at one end of the roller 55 that has spikes 56 extended therefrom, the spikes being divided to pulverize material that has been loosened by the ,scraper, prior to the rolling thereof.
This roller 55 is supported in the frame 57 that includes front bars 58 and rear bars 59, the bars 58 and 59 being connected to the shafts 60 that are eccentrically mounted in the bearings 61.
' These bearings 61 carry teeth that mesh with the teeth 62 of the bars 63, and are mounted in bearing housings 64 that are bolted to the side bars 30. The bars 63 are held in position by means of the rollers 63 mounted thereabove. The rear ends of the bars 63 are provided with teeth 65 that mesh with the gears 66 carried by the hand Wheels 67, that are rotatably mounted on the shaft 36.
When the hand wheels 6'? are rotated by the operator, the bars 63 will be moved horizontally, rotating the bearings 61, to raise or lower the frame 57, regulating the depth of operation of the roller 55 and the blade or scraper 68.
The reference character 68 designates a scraper which is supported directly in front of the roller 55, and operates to elevate the soil, prior to the pulverizing of the soil by the spikes of the roller, the spikes on the roller being of a length to touch material that does not move over the scraper.
Scrapers '70 are arranged on the side bars of the frame, and operate to scrape material from the rollers, maintaining the rollers in a clean condition at all times.
In the use of the device, the engine is started, which transmits movement to the roller, the spikes of the roller pulverizing loose material that forces back over the blade or scraper.
Supported on the inner surface of the side bars of the frame are stops 71 that lie in the path of travel of the shafts 60, with the result that when the frame 57 has been moved or lowered, the shafts 60 will contact with the steps 71, as pressure is directed against the scraper, thereby restricting further movement of the bearings 61, to the end that the frame 57 will be held in contact with the ground surface.
Having thus described the invention what is claimed is:
1. A land rolling machine comprising a frame, no eccentric bearings mounted within the frame, rollers mounted within the frame and having shafts mounted within the bearings, said bearings having teeth, bars having teeth meshing with the teeth of the bearings, means for operating the bars to rotate the bearings to raise and lower the rollers supported therein, and a central roller for normally supporting the machine.
