WHEELED SCRAPER.

Specification of Letters Patent.

Patented Aug. 18, 191 .1.

Application filed June 26, 1913. Serial No. 775,003.

To all whom it may concern:

Be it known that I, JOHN EDGAR STEELE, a citizen of the United States, residing at Terra Bella, in the county of Tulare and State of California, have invented certain new and useful Improvements in Vheeled Scrapers; and I do 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 make and use the same.

This invention relates to improvements in wheeled scrapers.

One object of the invention is to provide a wheeled scraper which is designed particularly for forming banks or checks for irrigating ditches.

Another ob ect is to-provide a machine of this character having means whereby the scraping scoop may be readily supported in position for forming banks or ditches, and which is provided with means whereby either side of the machine may be raised or lowered, thus enabling the scraping scoop to cut and scrape deeper on one side than on the other.

In the accompanying drawings: Figure 1 is a side view showing the scoop arranged for forming checks or ditch banks; Fig. 2 is a top plan view thereof; Fig. 3 is a vertical cross section of the machine taken on the line 55 of Fig. 1; Fig. 4 is a detail perspective view of the scraping scoop as arranged for leveling purposes; Fig. 5 is a similar view of the scoop when arranged for forming ditch banks; Fig. 6 is a detail perspective view of the standard for supporting the front end of the scoop when arranged for forming banks; Fig. 7 is a similar view of the standard for supporting the opposite end of the scoop.

In the embodiment of the invention, I provide a supporting frame comprising parallel side bars 1 and intermediate bars 2 which are connected at their forward ends by a front cross bar 3 and near their rear ends by a pair of parallel angle iron cross bars 4 and 5 which are spaced a suitable distance apart and are extended a considerable distance beyond the side bars 1 as shown. Revolubly mounted in suitable hearings on the side bars and front cross bar are crank axles 6 to the inner ends of which are rigidly connected axle adjusting levers 7 and revolubly mounted on the outer cranked ends of the axles are supporting wheels 8. By

means of the levers 7 the axles 6 may be rocked in their bearings thus swinging the cranked ends thereof upwardly or down wardly thereby raising and lowering one or both-sides of the machine as will be readily understood. The levers 7 are provided with spring projected pawls 9 which are adapted to engage the teeth of segmental racks 10 whereby the axles are locked in their adjusted positions for supporting the machine at the desired elevation.

The intermediate longitudinal bars 2 are extended beyond the ends of the side bars and have their outer ends connected by a rear cross bar 11. Secured to the rear ends of the bars 2 are short upwardly projecting posts 12 to which are pivotally connected the forward ends of an upper yoke 13, a similar yoke 14 having its ends fixed to a rock shaft 15 which is journaled in the ends of the bars 2 as shown. The rear ends of the yokes are pivotally connected to the upper and lower ends of a bearing sleeve 16 in which is revolubly mounted a caster wheel standard 17. On the lower end of the standard 17 is an offset head 18 to which is connected a fork 19 in which is revolubly mounted a caster wheel 20 which supports the rear end of the machine.

Fixed on one end of the rock shaft 15 is an upwardly projecting hand lever 21 which is disposed within convenient reach of the drivers seat 22 secured to the upper end of the sleeve 16. The lever 21 is provided with a spring projected pawl 23 which is adapted to engage the teeth of the segmental rack 24 whereby the lever is locked in its adjusted positions. By means of the lever 21 the shaft 15 may be rocked and the sleeve '16, caster wheel standard and the caster wheel connected thereto may be raised or lowered thereby supporting the rear end of the machine at the desired elevation.

Carried by the frame of the machine is a scraping scoop 25 which is preferably construoted from a curved metal plate having secured to its lower edge a sharp steel cutting and scraping blade 26. This scoop is to be employed for forming checks or banks for irrigating ditches, trenches and the like, the same is arranged at an angle across the frame as shown in Figs. 1 and 2 of the drawings. The scoop is supported and attached to the frame of the machine at its forward end by a standard 32 comprising a curved scoop engaging lower portion 33 and a rearwardly extending substantially horizontal upper portion 34-. The rearwardly projecting upper portion 3 10f the standard passes over the front cross bar 3 of the supporting frame and has its rear end flattened and bolted beneath the front angle iron cross bar at. The lower curved portion 33 of the standard is detachably secured to the rear side of the scoop near the upper edge there of by substantially U-shaped clips 35 and at its lower end said curved portion of the standard is bolted to the scoop as shown. The rear end of the scoop is detachably secured to the frame of the machine by a curved standard 36 which is secured at its forward end to the under side of the front angle iron cross bar t by a boltor similar fastening. The upper portion of the standard is also detachably secured to the lower side of the angle iron cross bar 5-by a clip, and the curved lower portion 36 is detachably secured. to the scoop by the clip 30 and a bolt 31. The standard 36 has its upper extremity detachably secured by a clip, to the lower side of the angular cross bar 5, and its lower curved portion detachably secured to the scoop 25 by the clips 30.

The machine is provided with a draft tongue or pole 39 to the rear end of which is secured a cross bar 4E0 the ends of which are connected to angle iron draft bars 41. The forward ends of the bars 41 are secured to the opposite sides of the pole and the rear,

ends thereof are adapted to be detachably and adjustably connected to the front cross bar 3 of the frame by hooks or other fastening devices which are engaged with a series of apertures formed in said bar 3. By thus attaching the pole to the front cross bar of the frame or to one side of the center of the machine as clearly shown in Fig. 2 of the drawings, I overcome any side draft which may be caused by the diagonal arrangement of the scoop. I

By providing a scraping scoop and means for detachably securing the same obliquely to the frame of the machine as herein shown and described, it will be seen that the dirt when scooped up is continuously discharged from one end of the scoop thus forming the bank. By providing the cranked axle for the front supporting wheels of the machine it will be seen that one or both sides of the front end thereof may be lowered to a greater or less extent to cause the scoop to cut more or less deeply and that by lowering the machine on one side and raising the same on the other the scoop will be caused Having thus described my invention, what I claim is:

The herein described scraper comprising a wheeled frame including cross bars, a scoop disposed obliquely across and beneath said frame, a standard having a curved rear portion secured behind the rear end of the scoop and a horizontal upper portion secured to one of said cross bars, and a second standard having a curved forward portion secured behind the forward end of the scoop and a horizontal upper portion extending from its curved portion rearwardly and passing over one of said frame bars and secured to it and to another frame bar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN EDGAR STEELE.
