SCRAPER.

narices.

Application filed May 6, 1909.

To all whom it may concern:

Be it known that we, HARVEY BINGAMAN and JOHN A. MILLER, citizens of the United States, residing at Harding, in the county of Harding and State of South Dakota, have invented certain new and useful Improvements in Scrapers; and we 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 which it appertains to vmake and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in Scrapers and comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described and then spe cifically defined in the appended claims.

The invention is illustratedin the accompanying drawings, in which Figure l is a perspective view of the scraper. Fig. 2 is a side elevation showing the scraper in a dumping position. Fig. 3 is a top plan view, and Fig. 4 is a sectional view on line 4 4 of Fig. 3.

Reference now being had to the details of the drawings by letter, A designates a frame which is of general rectangular shape and has a handle B at the rear end thereof and a cross piece C. Pivotally mounted in suitable bearings D of the frame are the stub shafts E which project from the opposite sides of the scraper E forming means for pivotally mounting said scraper, the points of mounting being in advance of the transverse center of the scraper. A bail-shaped draft member, designated by letter F, has eyesF formed at its ends and which have bearings upon said stub shafts. Said scraper has a forwardly curved arm H fastened to the back thereof and projecting over the scraper in the manner shown and is provided for the purpose of limiting the forward dumping movement of the scraper, as shown in Fig. 2 of the drawings. Resilient fingers I project from the back of the scraper and are bent to form the yielding hooks J. Mounted upon the opposite side strips of the frame and adapted to move a distance limited by the strapsl K is a sliding bar N which is normally held in such a position that, when the scoop is thrown back to its normal position, said hooks will engage Specification of Letters Patent.

it is moved upon the frame. F iXed to the bar N is the rod O which in turn is fastened to the lever L which is pivoted at L to the frame, and a spring Q is fastened at one end to the cross piece and its other end to said lever and serves to normally hold the latter in its farthest forward limit. A strap or loop R is fastened to one of the longitudinal side pieces of the frame and is adapted to guide the free end of said lever as it is moved backward and forward.

In operation, it will be noted that, when the scraper is in position to receive its load,

y by being drawn forward it will be held by the springs engaging over the plate in the manner shown in Fig. 1 of the drawings. Then it is desired to allow the scraper to dump, the operator may release the movable cross piece N from the hooks by pulling back upon one end of the pivotal lever, allowing the scraper to tilt forward and dump. The forward tilting movement of the scraper is limited by the end of the curved arm coming in contact with the ground. The scraper is returned to its normal position after it has passed the vertical line by vgravity and the resilient fingers will normally engage the cross piece and lock the scraper in readiness for receiving a new load.

From the foregoing, it will be noted that, by the provision of a device as shown and described, a simple and efhcient means is afforded which may be readily attached to ordinary Scrapers and afford means for holding the same for receiving the load and limiting the forward throw of the scraper.

What we claim to be new is l. A scraper, a frame and a draft rod pivoted thereto, hooks fastened to the rear edge thereof, a movable bar mounted upon said frame, straps upon the frame for guiding said bar, a lever pivoted to the frame, rods connectingr said lever and bar, means for guiding said lever, and a curved bar adapted to limit the forward'tilting movement of the scraper.

2. A scraper having angled stub shafts fastened to the opposite sides thereof, a draft bar and a frame pivotally mounted upon said shafts, bars fastened tothe rear end of said scraper and bent to form recesses and their free ends inclined and extending over the rear end of the scraper, a curved bar fixed to the back of the scraper and adapted to limit its forward tilting movement, a bar sliding upon the frame and adapted to engage said recesses to'hold the scraper from tilting, straps upon the frame for guiding said bar, a lever pivoted upon the frame, rods connecting the same with said sliding bar, and a spring fastened at one end to a part of the frame and its other end to the lever and serving to normally hold the latter at its farthest limit toward the scraper.

ln testimony whereof we hereunto affix our signatures in the presence of two witnesses.
