To allfwwm t may concern.'A f v Be fit' knownthat I, JOHN Kurz, a citizen of the United States, residing-atfSublimity, in the county offlvfarionand` State of Oregon, have invented a andy useful Improvement in Combined Graders and Drags, ofwhich'the followingis'a specification, reference .beingl had panying drawings.

My invention relates to that class of devices ordinarily vand chiefly used for graders and drags for the making of roads.

The object of my inventionk is to provide a deviceof this kind in which an ad justable part is arranged by means of which the soil can be shifted to a desired grade or be scraped or `dragged to level a surface. I attain these objects,v as well as other advantages, by the construction, combination and arrangement of parts illustrated in the accompanying drawings which formv a part hereo 1 Figure 1 is a side elevation of `the device.

Fig. 2 is a plan view of the same.

adjustable grader or scraper on the line 3-3 of Fig. 2.

Like letters and numerals refer to like parts throughout the figures.

A is a sled having namely, one runner B and a shorter runner B. The runner B is faced with ay metal l side 4 and both runners are beveled at their respective ends 5 5. A transverse brace 6 connects the runners in a suitable position in the sled frame. A forward transverse brace 7 connects the runners at the end. Means 8 are provided to attach to some suitable motive power means. A plow bar eX- tends from the beveled end 5 of the runner B below the brace 6, its forward end being rigidly secured to the runner B. It is rigidly secured near its other end below and to the brace 6. It must extend diagonally from the frunner B at an angle of degrees thereto.

The plow bar 9 is faced with metal 10. i

A moldboard 11 Ahaving a metal face l1' is secured to the rear end of the runner B by means of straps 12 having bolts 13-13. The bolts 13 are nearest the free end of the board 11 which has within itvertical slots or spaces 14 which allow a play of the bolts therein when the board is moved upwardly or downwardly. A brace 15 has one end secured to the runner B near its end and the l other end of the brace 15 issecured in a i suitable to the accom-f vstiltbar 17 has Fig. 3 is a sectional view of a part of the parallel runners,

brace 15 is ofsonie suitable material which will Y' allow an upward movement of :its end secured to. the moldY board. It: extendsat a right angle from therunner B. vUpon the end of the brace 15, over the runner B, a rounded saddle 16 is rigidly-secured. A one end resting upon the seat of the saddle 16 and is retained there in adjustedy position by means of the hand nuts,18. rIhe other end of the bark 17 is rigidly secured upon the mold board 11 in a position which retains lthe `bar at a right angle tothe board. The mold board 11 is arranged at a suitable angle to the runnerI Bl a suitable angle in relation of the plow bar 9.

It will now be seen that when it is desired to grade a road for example, or to shift the soil along longitudinal lines with the direction of movement of the machine, the bar 17 isadjusted so kthat the mold board has its lower edge practically i on the same plane with the lower edges of the sled runners. Upon drawing the sled, the soil is shifted by the plowkaround its end in the direction of the arrows 19. It then passes against the mold boardand is by it shifted outwardly between and must also be arranged positively at to the direction the Vfree end of the board and the rear end the nuts 18 and by reason of the play given theboltsl. The board 11 is secured at a desired height by adjusting the nuts 18. This position is shown by dotgd lines in Fig. 1. When the board 11 is thus raised the soil coming on' the plow as before is allowed to pass below the mold board and thesoil is scraped or dragged to an even surface longitudinally with the movement of the sled.

The simple construction of my device and the facility with which the mold board can be adjusted enables the operator successfully and completely to grade or drag, as he may desire, with the least loss of time.

positionV onthe ymold board 11.. 4 The device accomplishes by reason of the arrangement and construction oli' the mold board and related parte which l contend are dierent from any other devices for similar obj eats.

Having fully described my device l Claim: machine of the Character described, eomprieing a sled'franie having one'runner suiably Shorter than the other runner B, a vertical plow rigidlT secured Within the frame ,in a position "extending inwardly from the forward end of the runner B ai: an angle of l5 degrees thereto and its opposite end vcernlinating` at a predetermined distance from the runner B, a vertioel mold Copies of this patentvmay be obtainedfor five cents board having one end attachedto the rear end of the runner B and secured to the runner B by a brace so that theposition of said mold board is at a suitable angle with relation to said plow bar, a saddle secured uponvthenrnnner B near its rear end, a bar 17' rigidlyfseoured at one end to the mold board, its opposite end being seourable in an adjusted position over said saddle, substantially as described.
