To colt whom may concern:

Be it known that I, WILLIAM F. WARREN, a citizen of the United States, residing at Sheridan, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Wheeled 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.

My invention relates to im rovements in attachments for wheeled roa -scrapers, and more particularly to the one set forth in Letters Patent No.-661,094, granted to me November 6, 1900.

The object of the invention is to provide a simple and eflicient scraper-blade attachment of this character which may be readily applied to the scraper and adjusted so that it may be effectively used for repairing roads and for other urposes.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a lan view of my improved attachment a plied to a wheeled scraper. Fig. 2 is a si e elevation of the same, and Fig. 3 is a longitudinal sectional view.

Referring more particularly to the drawings, A represents the carrying-wheels of the scraper, which are journaled upon the ends of a transverse axle B, which has secured upon itcrank-arms c. The scoop D is suspended from the axle and consists of the sides F, a scraper-blade G, which is hinged at its upper rear ends to said. sides, as at g, the draftframe K, and the curved links I, which latter have their lower ends pivotally connected to the upturned ends of the blade G. The draft-frame K comprises the angle metal bars or stra s L, M, and K and has attached to it the raft pole or tongue J and a rearwardlyextending beam M, upon which the seat 0 is secured. The scoop D is sus ended by pivoted arms H and by links if, which latter have their lower ends pivoted upon the sides F of thescoop and their upper ends pivoted to thecranks c on the shaft B. The links it are provided about midway their lengths with recesses h to engage the axle when raisedgto their highest position to assist the Specification of Letters Patent. lip plication filed February 5, 1906.

crank-arms-in holding-the scoop elevated. Upon the shaft 13 is secured alever P, by means of which the scoop may be raised or lowered, as will be readily understood.

The scraper above described is the-same as that set forth in my patent previously referred to with the exce tion that the backboard of the scoop and its operating-lever are omitted. This is done when my improved attachment 1 is applied to the scraper. Ihis attachment comprises a frame 2, consisting of two pivotally-connected sections 3 4. The larger section 3 is pivotally connected to the sides F of the scoop, so that the frame may swing in a vertical plane, and the smaller section 4, which carries a, scraperblade 5, is pivotally connected to the section 3, so thatthe blade maybe adjusted angularly in a horizontal plane. The frame 3 preferably consists of a strap or bar of metal 6,bent in semicircular form and having its ends pivoted upon the sides F of the scoop, as shown at 7. These ends are connected by a cross-bar 8, which has secured between it and a clamp-plate 9 upon its upper face one end of a centrally-disposed longitudinal bar 10. face of its rear end a clamping bar or plate 11. The rear ends of the plates or bars 10 11 are spaced apart to receive the semicircular bar 6, as shown in Fig. 3, and between the intermediate portions of said bars is slidably and adjustably mounted the semicircular bar or plate 12 of the horizontally-swinging frame-section 4. The ends of the bar 12 extend rearwardly and are connected by a cross-bar 13, which is pivoted at its center, as shown at 14, to the bars 10 11. The extreme rear ends of the semicircular bar 12 are bent downwardly, as at 16, and have secured to their inner faces the scraper-blade 5, which latter may be of any desired form and construction. The blade may be secured in an angular position by any suitable means; but I preferably form in the central portion of the curved bar 12 a series of apertures 17, through which and through openings in the bars 10 1]. may be passed a pin or the like 15. When this attachment is applied to the scra er, as shown, and the latter is drawn forwar ly, the earth out by the scraper G passes over the same and is collected by the scraperblade 5 of the attachment. By adjusting the latter angularly the earth may be dis charged upon either side of the machine and The latter has secured upon the upper as rapidly as desired. This attachment renders the machine well adapted for repairing roads and for similar purposes.

From the foregoing description, taken in connection with the accompanying drawings, the.construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An attachment for scrapers comprising a vertically-swinging frame, a horizontallyswinging frame pivotally attached thereto, a blade carried by said horizontally-swinging frame, and means for securing said horizontally-swinging frame in an adjusted position.

2. An attachment for scrapers comprising a vertically-swinging frame, a horizontallyswinging frame consisting of a semicircular bar having downturned ends and a cross-bar, said cross-bar being pivoted at its center to said vertically-swinging frame, a scraperblade upon the depending ends of said semicircular bar, and means for adjustably connecting said semicircular bar to said vertically-swinging frame.

3. An attachment for scrapers comprising a vertically-swinging frame consisting of a semicircular bar having pivot-openings at its forwardly-projecting ends, a cross-bar and a longitudinal bar, a horizontally swinging frame consisting of a semicircular bar having rearwardly-projecting downturned ends, and a cross-bar connecting said ends, the lastmentioned cross-bar being pivoted upon said longitudinal bar, the scraper-blade being secured to said depending ends, and a pin passed through alining openings is said longitudinal bar and in the semicircular bar of said horizontally swinging frame, substantially as described and for the purpose set forth.

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