CHARLES A. SLAUGHTER, OF JACKSONVILLE, ILLINOIS.

ROAD SCRAPERAND GRADER.

SPECIFICATION forming part of Letters Azatent N o. 718,029, dated January 6, 1903.

Application filed April 1. 1902. Serial No. 100,925. (No modeLl To all whom, it may concern.-

Be it known that LCHARLES A. SLAUGETER,`

a citizen of the United States, residing at Jacksonville, in the county of Morgan and State of Illinois, have invented cert-ain new and useful Improvements in Road Scrapers and Graders; `and I do declare the following to be a fu1l,rclear, 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in road Scrapers and graders of the drag type.

The improvement comprehends a structural arrangement of elements to level a road as the apparatus is draggedover the surface and at the same time deiects any surplus material not utilized when at first encountered by the grader in such direction that it will be again subjected to another grading action and finally deliver what is left toward the center of the road-bed or, better, toward the center of the line of draft.

It is also'my purpose to construct a sectional grader which can be conveniently elevated should an obstruction be met with- In the drawings, Figure l is a perspective view of my improved road scraping and grading apparatus. Fig. 2 is a front elevation of the same to more clearly disclose the arch connection between the drags. Fig. 3 is a top plan view, and Fig. 4 is a side elevation.

The same numerals refer to like parts throughout all the figures.

l and 2 indicate lwhat I shall term, respectively, front and rear drags. Disposed intermediate the two drags are spaced-apart `the opposite ends of the beams 9 9 are connected tothe rear of the beams 3 3 by similar braces 12 12.

By referring more particularly to Fig. 3 it will be observed that the forward ends of the beams 9 extend considerably in advance of the rear of the beams 6 and that this eXtension may be changed to accord with varying circumstances; also that the angle of the rear drag may be altered I provide a series of openings 13 in each beam 9, and bolts 14 pass through openings in the ends of the braces l1 and 12 and selected ones of the openings 13. It will be further noted that the rear ends of the beams 9 do not come together. It is to adj ust this space also that the openings 13 and bolts 14 are used.

The .parts thus assembled, the operation is substantially as follows: The scraper and grader is drawn over the ground in the direction of the arrow 15 in Fig. 3, and by reason of the steel wearing or cutting plates being on the front of Jthe beams 6 a cutting edge is formed which readily scrapes or shaves the surface of the road smooth. In so doing the dislodged earth is carried along, and if ruts or other hollows are present such loosened earth lls them up; but should more earth be dislodged than there are ruts to fill, or if by some reason the ruts do not receive a suffe cient quantity of earth to pack them tight, the operation is repeated-that `is to say, by the peculiar arrangement of the two drags the surplus earth from the front drag is deiiected toward its outer ends and against the extended portions of the ends of the beams 9 of the rear drags, so that now the direction of the' travel of the earth is changed, although the i operation and function of the drag is identical with that of the front drag.

Any unevenness omitted by the front drag is IOC forthwith obviated by the rear drag, and correspondingly the earth is dislodged and gathered, and ruts, &c., treated as at first are sure to be packed and filled by the rear drag.

In an apparatus of this type there is almost to a certainty to be a final surplus of earth, and various expedients have been employed to direct it in some cases toward the center,A

others again away from the center of the machine, and others have endeavored to spread it. By my improvement I combine all of these various methods of disposing of vthe surplus earth, enabling me to reduce to a minimum any excessive amount of final surplus and yet gather and to a degree separate any rubbish and stones and deliver them in a row in approximately the center of the line of draft.

Should any unevenness be presented in the road, the hinge connection between the drags will allow the various beams to accommodate themselves. Hence the grading will not be effected by such conditions. Moreover, the arch-braces will serve to make a further resilient connection and assist to insure the road being thoroughly scraped.

My invention therefore possesses many decided advantages over the present state of the art, and it is thought its advantages and merits will be fully comprehended by those skilled in the art to which it appertains.

What I claim as new is l. A scraping and grading apparatus comprising a front drag, and a rear drag, arranged at an angle to each other, substantially as described, whereby the material scraped by one drag is thrown into the field of the other drag.

2. A scraping and grading apparatus comprising a front drag arranged atan angle, and a rear drag arranged at a different angle than the front drag, the front of the rear drag extending in advance of the termination of the front drag, substantially as described.

3. A scraping and grading apparatus comprising a front drag arranged at an angle, a rear drag arranged at a different angle, the

Afront of the rear drag extending in advance of the terminal of the front drag, and archshaped braces connected to the front and rear drags to form a space between the two drags, substantially as described.

4. A scraping and grading apparatus comprising a front drag, a rear drag arranged at a different angle, the front of the rear drag extending in advance of the terminal of the front drag and means adjustably connecting the two drags for changing the angles thereof, substantially as described.

5. A scrapingand grading apparatus comprising a front drag composed of a pair of angularly-arranged beams, a pair of beams intermediate said drag, a hinge connection between the said beams, hinges connecting the intermediate beams and the beams of the drag, a rear drag composed of a pair of angularly-disposed beams which extend forwardly beyond the terminal of the front drag, means connecting the frontdr'ag and the rear drag, means connecting the rear drag-beams and the intermediate beams, and means for changing the angle between the two drags, substantially as described.

6. A scraping and grading apparatus comprising a pair of beams,hinges securing said beams together, a pair of beams hinged at or near the front end of the aforesaid beams, forming a front drag, and a pair of beams positively secured at or near the rear end of the first-named beams forming a rear drag, the forward ends of the beams of the rear drag extending beyond the terminal of the front drag, substantially as described.

7. A scraping and grading apparatus comprising two sections exibly connected, each section being composed of an angularly-arranged front bar, a rearwardly-extendingbar which is at a dierent angle than the front bar, means for supporting the rear end of the rearwardly-extending bar, means connecting the latter bar and the front bar whereby a space is formed between the two, and means for maintaining a space between the ends of the rearwardly-extending bars when the two sections are secured together, substantially as described.

8. A scraping and grading apparatus comprising a front, approximately A-shape drag, a rear approximately A-shape drag,said drags diverging in opposite directions, the rear drag extending at its front end beyond the rear of the front drag while the rear end of the rear drag is open, and means connecting the two drags together, whereby a space is formed between them, substantially as described.

9. A scraping and grading apparatus comprising means for scraping and grading the earth and simultaneously forcing the surplus earth from the plane of action, means for simultaneously gathering the said surplus earth and scraping and grading in the plane of the first-named means, but in an opposite direction thereto, substantially as described.

l0. A scraping and grading apparatus comprising means for scraping and grading the earth and simultaneously forcing the surplus earth outwardly, means for simultaneously gathering said surplus earth and scraping and grading in the plane of the firstnamed means but toward the center, substantially as described.

1l. A scraping and grading apparatus comprising a diverging drag, and a converging drag, the end of one drag extending beyond the other drag, substantially as described, whereby the material scraped by one drag is thrown into the eld of the other drag.

In testimony whereof I aliix my signature in presence of two witnesses.
