WITNESSES I INVENTOR HUGH OHARE, OF MOUNT PLEASANT, IOWA, ASSIGNOR TO JOHN F. LEEOH, OF SAME PLACE.

RGAD SCRAPER.

SPECIFICATION forming part of Letters Patent No. 392,567, dated November 6. 1888.

Application filed July12, 1888. Serial No. 279,775. (No model.)

To aZZ whom it may concern:

Be it known that I, HUGH OIIARE, a citizen of the United States of America, residing at Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and usefulImprovements in Road-Scrapers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in road-scrapers, the object thereof being to provide means whereby the angle of the scraper with respect to the draft can be readily changed; and it consists in pro viding the scraper-board, which is pivoted to the draft-beam, with rearwardly and inwardly projecting arms adapted to be adjustably secured to said draft-beam to change the angle thereof, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings Figure l is a perspective view of my improved scraper, and Fig. 2 is a side view.

. A refers to the axle, of ordinary construction, which may be provided with a draft tongue or shafts and with means for pivotally securing thereto a beam, B, to which a scraper,

3, is pivoted centrally by means of a bolt or pivot, a, which is rigidly secured to the scraper 3 5 C and passes through aperforationin the beam 13 to hold the scraper at an angle. The beam B has attached to its upper side a seat, D, upon which the driver sits.

To the ends of the scraper G are attached 4o rearwardly-curved arms E and F, the front ends of which are bent downwardly and secured to the rear side of the scraper by suitable bolts. The ends of the arms E and Fare provided with one or more perforations, 5 through which bolts pass to engage with perforations b in the rear end of the beam 13.

inserting the pivot-bolt in different perforations. By providing the scraper with these rearwardly-curved arms the same is thoroughly braced, and they are not liable to be bent or unduly strained by the earth removed by the scraper and obstructions striking the same, as is liable to occur when the arms extend forwardly above the scraper. In practice I have found that this form of brace-arms gives better results and is more convenient than the forward brace-arms heretofore employed.

Having thus described my invention, I claim I. In a road-scraper, the combination of the truck, the reach pivoted thereto and provided at its rear end with a longitudinal series ofperforations, a scraper provided centrally with a bolt to afford a pivotal connection with the reach, and rearwardly-extending adj ustingbraces secured to the outer ends of the scraper and provided with boltholes arranged to register with the holes of the longitudinal series at the rear end of the reach, substantially as described.

2. The combination, in a scraper, of a straight beam, 13, provided with a seat, D, a scraper, O, centrally pivoted to the beam, rearwardly-extending arms E and F, secured to the ends of the scraper and to the rear portion of the beam B, said arms being of different lengths, so as to be secured to the beam at different points, substantially as shown, and for the purpose set forth.

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

HUGH OHARE.
