The object of the present invention is Ito imnot specifically I proveand simplify the hoisting means of a scrap er or the like while maintaining a maximum amount-of'rigidity'therein. I If: The manner in which the above and other-ob jects of the invention are accomplished will be readily understood onreference to the foll owing specification when read in conjunction with the accompanying drawings'whereinz I Fig; -1' is an elevation viewof the scraper apparatus' embodying the present invention and shown in'digging position; I II Fi'gpf2 is a. plain iew :d th scraping ratus; (:1 t

the links 39 provide a'three point support in a verticalplan .which,:due to the II I I II spacing of the axes of the .pins' 36- 3 1 Y40 (and- 42 afiords a maximum amount of rigidity commensurate with .the strength of the various structural-elements involved.

interfering with the I port in a horizontal plane which affords a maximum amount of transverse rigidity for the articulated connection between the scraper body and the post 30.
The forward end of the scraper body is raised and lowered along the post 30 by means of a cable 43 wrapped around and anchored to a small diameter section 44 of a differential hoist drum 45 (Fig. 4). Drum 45 is journaled on a transversely extending shaft 46 supported by brackets 41 depending from the beams l2 and I3. Cable 43, after leaving the small diameter section 44 passes around a pulley 48 rotatably mounted on a bracket at the top of post 30 and is then led around a pulley 49 rotatably mounted in a pulley block 50. Block 50 is pivotally mounted on a pin extending between the beams 12 and I3. On leaving pulley 49, cable 43 is passed over a pulley 52, also rotatably mounted at the top of post 30 and is thence wrapped around and anchored to a large diameter section 53 of the drum 45. A second cable 54 is wrapped around and anchored to a second large diameter section 55 of drum 45 and thence passes under a pulley 56 rotatably mounted in an opening 30' extending through post 30. The cable 54 is preferably operated by a power driven winch (not shown) provided on the tractor and under control of the tractor operator. When the cable 54 is drawn by the winch the drum 45 will be rotated so as to cause a differential action upon the cable 43 to shorten the length of the same and thus draw the scraper body upwardly along the post 30.
The above mentioned hoist mechanism permits a substantial raising and lowering movement to be applied to the scraper body with a minimum rocking movement applied to the post 30. There-. fore, the weight of the scraper apparatus is applied substantially longitudinally of the post 33 throughout the travel of the bearing blocks 34 and 35, thereby reducing complicated stresses occurring in the post and enabling the same to be made as light as possible while forming a simple arrangement of levers to effect the hoistingroperation. Furthermore, this hoist mechanism forms a compact arrangement resulting in a reduction of weight of the apparatus.
