6 Claims. 1

The present invention relates to an attachment for tractors particularly adapted for use as a scraper for moving or piling dirt or .snow or for scraping the dirt. or snow and movingit to one side of the driveway.

The principal object of the present invention is to provide a device of the character which can beeasily attached. and detached from the tractor, easily adjusted for piling or for scraping to one side either snow or dirt and to provide a device which is lightand. strong andeasily manufactured at low cost.

An object of the present invention is to pro- Vide a frame including an elongated rearwardl-y extending element on which the scraper blade holding head is slidably mounted, so it can be differently positioned, longitudinally and having means whereby the blade may be quickly and easily moved to. different transverse angles or reversed.

One of the objects of the present invention is to so mount the device on the tractor whereby the blade, particularly when in its rearward position, may be raised a considerable distance above the ground or road surface.

Another object of the present invention is tn provide means whereby the blade may be reversed on itsv supporting bracket for pushing operations as. well as pulling.

To these and other useful ends myinvention consists of parts, combinations of parts or their equivalents, and mode of operation, as hereinafter described and claimed and shown in the accompanying drawings in which:

Fig. 1 is an elevational view of my .device attached to a conventional tractor, the near rear wheel of the tractor being removed for obvious reasons.

Fig. 2 is a top view of the device as shown in Figure 1, except havin the blade positioned at an angle, and not showing the retaining plates as illustrated in Figure 1.

Fig. 3 is an elevational, partially sectioned view of the attachment with the blade reversed and set at right angles to the tractor for being pushed into the work.

Figs. 4, 5 and 6 illustrate a modification.

In the drawings the tractor is, in its entirety designated by reference character A; the frame of my device is, in its entirety designated by reference character B and the blade holding mechanism in its entirety, is designated by reference character C. Member A may be conventional and supplied with a hydraulic lift which is generally positioned withinthe frame IU of the-tractor having outwardly extending shafts I'l-ll which protrude through bearings in frame [0 and have mounted on the. endsv thereof, arms I2'|.2', the rear ends of which are operatively connected to. draw-bars .|3.l3 by means of suitable links i l-4 G, whereby .the device maybe hydraulically raised, lowered or held in any desired position, a. manner .too well known to require further .description. or illustration.

Frame l3. comprises pref erably, a relatively large tube 29. having secured to itsforward. end, a depending member 2i preferably, by electric weld as at 22 and having preferably a brace member 23 adapted to. strengthen the structure. Member 21 is. suitably secured to a transverse tube memoer to the ends. of which. the rear ends of members iii are .hingedly mounted as at '25-'25.

.On the. upper forward end of member .20. I secure. a post .25 as illustrated, having a brace. 21. These members are preferably electrically welded togetheriand' to.,member 2d. The'u-pper end of member 2.5 is operatively connected to the tractor by means of alink 28 as. at '29 and 30;, thusmember B will be held in its various positions as shown by full and dotted lines in Figures 1 and 2.

It .wi-llbe. seen. that because of the relative angles of members 13 and 2.8, when member 13- is. lifted to its highest position as. shown .by dotted lines in Figure 1., the. scraper blade, particularly when in itsrearmost position on member 20, be moved a considerable distance above the ground; thus clearly the scraper blade may be caused to clear a large accumulation of dirtv or snow. However it, will be understood that the power lift, being under control of the operator, the height of the. blade. can be manipulated for leveling and for filling pockets in the road surface.

Member Ccomprises preferably a tube 40 which is slid'ably mounted on tube 20', the tube 28' and member 49 having spaced holes for linchpins al -4| so member 48 may be held in the position shown 'in Figures 1 and 2 or in the position shown by dotted lines in Figure 1. It will also be noted that memberdfil may be reversed on tube 20 as i1- lu'str-ated' in Figure 3 for a purpose which will hereinafter appear.

'A plate 42' is preferably electrically welded to member 41) andhas openings through which l-inchpins 4 extend. These linchpin-s may answer as the sole means for holding" member 40in position on member 2-8. However I may supply two bolts 3939-' for holding member 4'0 in its desired position. The blade carrying member comprises a plate-43- having a number of openings 4"? for the reception oi-l-inch-pins M, these openings wear-ing strip being on a radius with a shaft 44 which is secured to plate 42, preferably by electric welding, the shaft extending freely through plate 43. Plate 43 has secured thereto, preferably by electric welding, a tube 45 and being further secured to plate 43 by means of a brace 46. Tube 45 fits loosely over shaft 44 and a collar 48 is secured to the bottom of shaft 44 for the purpose of holding member 45 and its connecting parts into the position shown in Figures 1 and 3.

Thus it will be seen that members 43, 45 and 46 may be turned to three or more positions on shaft 44 and held linchpins 4|; that in addition to the fore and aft positions made available by simply removing members 4| and bolts 39, member 48 may be removed and reversed.

I provide a scraper blade 58 having preferably removably secured to its lower edge, a cutting and Blade 56 is preferably curved, about as shown in Figure 3, the upper edge being flanged as at 52 and suitably secured to member 43, preferably by electric welding, the lower edge being secured to tube 45 by means of a plate 53, preferably by electric weld. I also provide spaced stiffening angle bars 54, their ends being, preferably welded to members 52 and 53. I

Thus it will be seen that by removing collar 48, the scraper blade and its connecting parts may be removed. The advantage of this design is that other types of scrapers or earth engaging means may be supplied. It will be seen that for reversing the scraper blade as shown in Figure 3, member C may be removed by simply removing linchpins 4| and bolts 39; or if desired the scraper blade and its connecting parts may be easily removed from shaft 44 and reversed. V

In gathering and piling snow and dirt it is frequently desirable to prevent accumulating material from escaping around the ends of the scraper blade and for this purpose I provide plates 55 (see Figure 1) having a shape, about as shown, and being detachably secured in any convenient manner to the ends of the blade. v

Figures 4, 5 and 6 illustrate a modification. In this design I illustrate a means for changing the vertical angle of the frame and blade wherein a plate 58 is secured to member 26, having a series of holes 59 to any one of which link 28 may be attached by bolt 29. A sleeve 66 is provided which is secured to member 29 by means of bolts 39, for positioning the head difierently, as illustrated in Figure 1. Bars 62 are welded to member 66 as illustrated in Figures 4, 5 and 6 and a plate 64 is welded to bars 62. An opening 66 in plate 64 is provided for a bolt 61 which acts as an axis for the blade holding frame. Bars '62 provide an opening as shown in Figure 6 for the reception of the head of bolt 61. V

I provide a plate 68 through which bolt 61 extends, plate 64 is provided with slotted openings 69 at each end and plate 68 is provided with three or more openings 10 at each end, openings 18 being on a radius with bolt 61 as its center.

In each opening 69 I provide a bolt 1| having 7 a nut 12 provided, preferably with an extending hand grip 13; thus it will be seen that bolts 1| may be conveniently loosened and moved out of openings 18 so plate 68 may be turned in either direction and securely fastened.

I provide a scraper member 15 which is shaped, about as shown in Figure 4, the upper end 16 extending rearwardly, bolt 61 extending through this member, as shown in Figures 4 and 5. Memin these positions by means of .4 ber 16 is preferably securely welded to member 68. At the lower edge of member 15 I secure a blade cutting member 18 having a rearwardly extending flange 19.

I provide spaced brace members 8680 which are preferably welded tothe outer edges of member 68 and to member 16, the bottom edges being Welded to member 19, as at 8|. These members contact the rear surface of member 15 and are welded thereto. At the ends of members 15, 16, 18 and 19 I provide stifiening braces 8'2 which are welded thereto, to thereby cooperate with members 86 to form a strong blade supporting unit.

It will be seen that the assembly as shown in Figures 4, 5 and 6 may be moved to different positions on member 26 and that by simply loosening bolts 1| and moving them out of slots 18, the blade may be turned to the right or left.

The advantage of this modified design is that it is simple, light, strong, easily manufactured atlow cost and that by simply raising member B the scraper carrying head may be removed, or the scraper blade adjusted to a desired angle or position or reversed on bolt 61 as an axis for use as a bulldozer. 7

It will be understood that links M are easily adjusted as to length so the blade can be angled for terracing or roadway shoulder work and the like. In Figure 2, I illustrate the scraper blade in position for terracing. For this kind of work I secure a land slide plate to the forward end of the blade having a brace 86, plate 85 acting like the land slide of a mold board plow; thus to prevent the side thrust from being transmitted to the tractor or the connecting parts between the blade and tractor. 7
