GRADING-MACHINE FOR BUILDING AND REPAIRING ROADS- Specification of Letters Patent.

Patented May 28, 1907.

Application filed February 15,1907. Serial No- 357,526-

To all whom, it may concern: y

Be it known that I, WALTER ATLAs J owes, a citizen of the United States, residing at Coolidge, in the county of Thomas and State of Georgia, have invented a new and useful Grading-Machine for Building and Repairing Roads, of which thefollowing is a specification.

This invention relates to grading machines for use in building and repairing roads.

The object of the invention is to provide a novel arrangement of disk plows for loosening the soil.

A still further object is to provide powerful and efficient means adapted to be readily operated manually. for directing the disks toward or away from the surface of the ground so as to make the cuts of various de sired depths.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of the machine; Fig. 2 is a plan view thereof; Fig. 3 is a section on line x-x, Fig. 2; and Fig. 4 is a section on line y-y, Fig. 2.

Referring to the figures by characters of reference, 1 is a frame of suitable proportions mounted on supporting wheels 2 in the usual or any preferred manner and pivotally connected to the sides of the frame adjacent the rear end thereof are depending arms 3 con-,

nected to opposite portions of a diagonally arranged scraper blade 4. One of the arms 3 extends upward to form a lever 5 carrying a spring pressed dog 6 adapted to engage a toothed sector 7 so as to lock the scraper in any desired position. A supporting bar 8 is pivotally connected to one side of the frame and has a hooked end 9 adapted to extend under one of the arms 3 so as to hold the blade 4 out of contact with the ground when the same is not in use. Although the scraper has been shown and described it is to be understood that the same constitutes no part of the present invention and that other constructions than that shown may be employed if desired.

Guide strips 10 are secured longitudinally upon the sides of the frame 1 and slidably mounted between these strips and the sides of the frame are guide plates 11 formed at the ends of a cross strip 12 extending under the frame. These guide plates have inwardly extending flanges 13' at their upper edges which bear upon the sides of the frame 1. The cross strip 12 has a rack bar 14 secured transversely thereon adjacent one end and this rack is engaged by a sector 15 formed at the lower end of a lever 16 which is fulcrumed upon one side of the frame 1. A toothed sector 17 is disposed adjacent the lever and is adapted to be engaged by a spring pressed dog 18 so as to hold the lever in any position to which it may be adjusted. Hangers 19 are rigidly connected to the cross strip 12 and extend downward therefrom preferably at an incline. The lower ends of these hangers are slotted as shown at 20 and are provided with retaining strips 21 which are bolted or otherwise fastened thereto and serve to close the lower ends of the slots.

Arms 22 are pivoted to the sides of the frame 1 and extend downwardly therefrom and journaled within the lower ends of these arms is a shaft 23 which is normally diagonally disposed in relation to the frame 1. Arranged on this shaft is a plurality of disks 24 each of which has a sleeve 25 rotatably mounted on the shaft. These sleeves serve to hold the disks spaced apart desired distances. Shaft 23 and certain of the sleeves thereon are seated within the slots 20 and are designed to work longitudinally of the slots when the arms 22 are swung upon their fulcrums. 7

It is of course understood that when the parts are disposed as shown in Fig. 3 it becomes impossible for the arms 22 and the shaft thereon to swing because they will be held against movement by the hangers 19. These hangers can only be shifted with the cross strip 12 and said strip is normally locked against movement by means of the dog 18 and the sector 17. When it is desired to swing the disks 24 downward so as to increase the depth of the cut into the soil the lever 16 is swung toward the rear of the machine and as a result the mutilated gear 15 will force the rack bar 14 forward. This movement of the rack bar will cause a corresponding movement of the cross strip 12 and the hangers 19 will press against the rotatable element therein and cause the arms 22 to swing forward and downward thereby carrying the disks 24 therewith. Of course the arms 22 are incapable of moving independently of the hangers 19 and when the hangers l thereto, a shaft ournaled within said ch are once locked against movement by means of the sector 17 and dog 18 the disks 24 become fixed in relation to the frame 1. Should it be desired to raise the disks from the ground the movement of the lever 16 is reversed and this will cause the hangers 19 to pull downward onj'shaft 23 and as aresult the arms 22 will be swung upwardly and rearwardly. It will be seen that by providing lever 16, rack bar 14 and hangers 19 a powerful leverage is obtained upon the arms 22 and therefore the disks 24 can be readily forced into the soil and easily raised therefrom. Of course as the disks are arranged diagonally in relation to the frame 1 it is apparent that as they move forward they will out furrows within the ground and the scraping blade 4 which follows the disks will gather the loosened soil and deflect it laterally from the machine.

Importance is attached to the particular means devised for adjusting the disk plows because of the powerful leverage which is obtained and also because of the compact and durable nature of said mechanism.

What is claimed is:

1. A machine of the character described comprising a portable frame, a plurality of earth engaging devices, pivoted supports therefor, and slidable means for actuating the supports.

2. The combination with a portable frame; of a plurality of earth engaging devices, pivoted supports therefor and suspended from the frame, and slidable means for actuating the supports to raise or lower the earth en gaging devices.

3. The combination with a portable frame; of a shaft, earth engaging devices connected thereto, shaft supports pivotally connected to the frame, and slidable means engaging the shaft to swing the supports.

4. The combination with a portable frame;
