To all whom t may concern:

Be it known that I, JOEL W. HUTTON, a citizen of the United States, residing at Tony, in the county of Carbon, State of Montana, have invented certain new and useful Improvements in Land-Levelers; and I 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 make and use the same.

This invention relates to devices for leveling land and more particularly to that class of such devices which includes wheeled scrapers.

The primary object of the inventionis to provide an implement of this character including a blade of such construction that it may be utilized as a scraper or as a leveler, as is desired and according to the condition of the ground,

Furthermore, a novel compact means is provided for raising and lowering the blade into and out of engagement with the surface of the ground and a novel means of mounting the blade is lalso provided.

With the above and other objects in view, the present invention consists in the construction and arrangement of parts, shown in the accompanying drawings, in which:

Figure 1 is a side elevation of the invention, one of the wheels being omitted to more clearly show the parts the same being in their elevated position. Fig. 2 is a similar view of the opposite side of the implement showing the blade in its lowered position. Fig. 3 is a rear elevation of the implement. Fig. 4 is a top plan view thereof, and, Fig. 5 is a detail vertical sectional view through the scraper and leveling blades.

Referring more specifically to the drawings, the numeral 6 denotes a tongue upon the opposite side of which and adjacent the rear end thereof is journaled an axle 7 upon the ends of which are mounted wheels 8, and secured at its forward end upon the tongue 6 is the usual spring seat standard 9 carrying a seat 10.

Pivoted as at 1], to one side of the tongue 6 is the forward end of a lever 12 and pivoted to the said lever at a point directly in rear of the rear end of the tongue 6 is a blade standard 13. As shown in the drawings, the said blade standard is of practically the same width as the tongue 6 and is pivoted to the lever 12 in such a manner that it depends therefrom directly in rear of the rear end of the said tongue and hence serves to hang the blade directly centrally of the implement.

The lower end of the blade standard 13 abuts the upper edge of a leveling blade 14 and is secured in this position by means of a pair of plates 15 which are bolted or otherwise secured to the front and rear faces of the standards 13 and the blade 14. The upper edge of the leveling blade 14 is slightly beveled to cause the blade to lie at an obtuse angle to the standard 13. In order to brace the blade in its proper position, I provide a pair of brace-rods 16 which are bent at their forward and rearward ends to form eyes 17 and 18, the forward ends of the brace-rods being engaged with the axle 7 and the eyes at the rear ends of the rods being loosely connected with eye members 19 secured to the upper edge of the leveling blade 14. As shown in Fig. 4, the rods 16 diverge rearwardly and hence hold the blade 14 rigid under all circumstances.

Throughout the entire length of its lower edge the blade 14 is beveled as at 20 and bound with a strip of metal 21 which lies against the bevel-face 2O of the blade and has iianges 22 and 23 extending upwardly therefrom and lying against the front and rear faces of the blade, the object of the said strip being to prevent injury to the blade when in use. The said blade 14 is also provided with a series of bolt openings 24 through which may be engaged bolts 25 for the purpose of securing a scraper blade 26 to the leveling blade 14 when it is desired or becomes necessary by reason of the hardness of the ground and it will be readily understood that by providing this detachable scraper blade, the implement is adapted for use under any conditions of the soil.

One end of a plate 27 is bent laterally at right angles as at 28 and secured to the upper face of the tongue 6 at the rear end thereof and the said plate extends upwardly from this attaching portion 28, is curved rearwardly and thence extends downwardly as at 29, the forward edge of its downwardly extending portion 29 being in spaced parallel relation to the extreme rear end of the tongue 6 and arranged for the reception therebetween of the said'tongue of the blade standard 13. Along its rear edge the downwardly extending ortion 29 is provided with a series of rac teeth 3() and mounted upon the lever`12 in position for co-opera IIO tion With the ratchet teeth 30 is a pawl 31 which. may be retracted by means of the usual hand-lever.

What is claimed is: y

l. An implement of' the class described comprising a frame, a lever mounted in the frame, a blade standard connected With the lever and depending therefrom, a blade carried by the standard, means for holding the lever in adjusted position, and brace-rods connected with said blade and said frame and arranged to brace the blade in its various adjusted positions.

2. An implement of the class described comprising a tongue, a lever pivoted to the tongue, a blade standard pivoted to the lever and depending therefrom, a blade carried by the standard7 a rack plate mounted upon the tongue and arranged for the reception olE the blade standard therebetween and the tongue, and a pawl mechanism carried by the lever for eo-operation with the rack-plate.

In testimony whereof7 I aHiX my signature, in presence of tWo Witnesses.
