BUA1D-SURAPEEL Application filed. August 18, 1908.

To all whom it may concern:

Be it known that l, Josnrrr T. BLAND, a citizen of the United States, residing at Pittsboro, in the county of Chatham and State of North Carolina, have invented new and useful Improvements in Road-Scrapers, of which the following is a specification.

This invention relates to im rovements in road scrapers, the ect of the invention being to provide a simple, efficient and inexpensive type of device of this character which is equally well adapted for leveling ground, building terraces and scraping out roadv ditches, and in which the scraping blade is adjustable for these different operations.

The invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompm nying drawing, in which Figure 1 is a perspective view of a road scraper embodying my inventioi i 2 is a side elevation of the same showing dr 'ent positions of adjustment of the blade in full and dotted lines.

The frame of the implement comprises a pair of rearwardly diverging bars or beams i, suitably connected at their forward ends and provided with any preferred type of draft clevis 3 are provided for Handle bars guiding and controlling the implement and are connec ed at their forward ends to the side beams by bolts These bolts are adapted to be passed through front or rear sets of openings 5 and 6 in the beams to secure the handles at different positions of adjustment.

A transverse scraping blade 7 is arranged beneath the rear ends of the side beams 1 and is formed with a lower forwardly curved scraping edge 8. This blade is supported by a frame comprising a pair of hanger bars or strips 9 reinforced at their upper ends by cross brace 10. Preferably, the hanger bars are composed of strips of metal having their upper portions arranged edgewise in the longitudinal plane of the machine and their lower portions disposed cdgewise transversely of the machine by quarter twistin the strips at the points of intersection of said portion, the blade being secured in any preferred manner to the lower portions, as shown. The hanger bars are pivotally con- Specificaticn of Letters Patent.

nected to the rear ends of the beams 1 by pins or bolts 11 and are also pivotally connected with the handle bars 3 by pins or bolts l2. By this construction the blade and its supporting frame may be swung forwardly or rearwardly on the beams 1 for adjustment to incline the blade at a rearward or forward working angle, as shown in dotted and full lines in Fi 2. The bolts 4 are passed. through the front set of openings 5 to secure the handle bars and scraper in the dotted line position and through the rear set of openings 6 to secure the same in the full line position. The blade may thus readily and conveniently set for ordinary leveling, for terrace building work and fo ditch clearing or scraping, thus rendering the implementadaptable for general work.

It will be noted that the construction is simple and adapts the device to be manufactured and sold at a low cost, and that the adjustment of the blade requires merely the engagement of the securing bolts l with one or the other of the sets of bolt openings.

Having thus fully described the invention, What is claimed as new, is:

1. A scraper comprising a main frame, a hanger frame pivotally mounted upon the rear end of the main frame and extending above and below the same, a transverse scraping blade mounted upon the lower end of the hanger frame, handle bars pivotally connected with the upper end of the hanger frame, and means for adjustably securing the forward ends of the handle bars to the main frame.

2. A scraper comprising a main frame including rearwardly diverging bars, hanger bars pivotally mounted upon the rear ends of the diverging frame bars and extending above and below the same, a transverse scraping blade secured to the lower ends of the hanger bars, handle bars pivoted to the upper ends of the h anger bars, and means for adj ustably securing the front ends of the handle bars to the diverging frame bars.

3. A scraper comprising a frame including rearwardly diver ing side bars rovided with front and rear sets of openings, hanger bars pivotally mounted upon the rear ends of the frame bars and extending above and below the same, a transverse scraper blade secured to the lower ends of the hang r bars, a brace In testimony whereof a'l'fix my signature in presence of two witnesses.
