ROAD-SCRSAPERJ SPECIFICATION formingpart of Letters Patent No. 700,594, dated May 20,1902.

Application'filed August 9,1901; Serial No. 71,472. N m l- To (all whom it may concern:

Be it known that I, THOMAS TILSON, a citizen of the United States, and a resident of Meyers Falls, in the county of Stevens and State of Washington, have invented a new and Improved Road-Scraper, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a road-scraper of such construction that a main and an auxiliary draft-beam are employed capable of such adjustment relative to each other and to the blade or shovel that the dirt may be directed either to the right or to the left hand side of the implement and so that in ordinary ground the ground need not be turned up prior to the passage of the scraper over it, as the scraper will act as a plow as Well as an evener.

A further purpose of the invention is to provide means whereby the scraper will remove dirt from a hillside without the necessity of driving the team close to the hill or bank.-

The invention consists in the novel con-' struction and combination of the several parts, as will be hereinafter fully set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improved s'craper adjusted and fitted for working upon a hillside. Fig. 2 is a similar view of the scraper arranged for leveling aroad or street, and Fig. 3 is a vertical transverse sec-' tion through the blade or shovel at the point where the extra draft-hook is applied when the implement is to be used for hillside-work.

The blade or scraper A may be made'inone piece, but, as illustrated, it is usually made in two sections an upper sectionlO and a lower section 11-the two sections at their abutting longitudinal edges being brought close together. The lower edge 12 of thelower section 11 of the blade or shovel is curved forward and upward to a greater or less extent. A back board or support B is employed, upon the front face of which the sections of the shovel or blade A are bolted or otherwise secured. This back support B for the shovel or blade is inclined downward and forward at the bottom portion of its back face, as is illustrated at 13 in Fig. 3, so that the curved edge'12 of the blade or shovel, which is the cutting edge,--is left unobstructed and free to act. Handles 14, which resemble plow-handles, are secured in suitable manner to the back support B atits rear face, and the back support B and shovel or blade A extend be yond the outer side faces of the handles to a greater or less extent. The ends 15 of the back support are beveled in direction of the blade or shovel, as shown in Figs. 1 and 2. Straps may be employed for attaching the blade or shovel at its central portion to the back support, and straps may likewise be attached to the back of the blade or shovel, which latter straps when used are carried upward and secured to the forward faces of the handles 14;.

A hook 16 is located at each end of the blade or shovel A, extending beyond the ends of the blade or shovel, as shown in Figs. 1 and2, and these hooks may be individually secured to the back support B or may be formed at the ends of a single strip of metal attached to said support B, as shown in Fig. 2.

An aperture 17 is made in the upper section of the blade or shovel A and in the back support B about centrally between the top and bottom and between the center and righthand end, as is shown in Fig. 2. When the implement is to be used for hillside-work, the shank 18 of a hook 19 is passed rearward through this aperture 17, and the shank is held in position on the body of the implement by means of a pin 20 or its equivalent attached to the body by a suitable length of chainfor example, as is illustrated in Fig. 3.

When the implement is to be used for hillside-work, an auxiliary blade or shovel A is employed, preferably made in one piece. This auxiliary blade or shovel A is secured by bolts 21 or their equivalent to the front face of the main bladeor shovel A at its right-hand end and extends beyondthe righthandend of the main blade orshovel and usually beyond theihook 16 at such end.

In connection with the bod-y of the implement just described a main draft-beam O is employed and an auxiliary draft-beam 0'. Each of these draft-beams is provided with beam 0 is at all times connected with the left-hand hook 16 of the body of theimplement. for leveling upon a straight road, the eye of the auxiliary draft-beam is attached to the right-hand hook 16 on the body; but when the implement is to be used for hillside-work an additional hook 19 is added to the body and also the auxiliary blade or shovel A, and the inner end of the auxiliary draft-beam O is then connected with the added hook 19, as is also shown in Fig. 1.

At the right-hand side of the main draftbeam 0 a series of sockets 23 is longitudinally arranged. These sockets extend from a point near the center of the main draftbeam to its forward end, and at the forward end of the main draft-beam O a clevis 24 of any desired type is located. The auxiliary draft-beam O is provided with a hook 25 at its forward end, and this hook is adapted to enter any one of the sockets 23, formed upon the main draft-beam.

When the implement is to be used for leveling a road, for example, the parts are assembled as shown in Fig. 2 The main beam 0 is connected with the left-hand. end of the shovel or blade A, and the auxiliary beam at its rear end is connected with the opposite end of said blade or shovel, while the forward end of the auxiliary beam is connected with any one of the sockets 23 that may be required to give the blade or shovel A an inclination toward the right or toward the left, as demanded by the character of the work to be done, or the said shovel or blade may be made to travel more or less straight by connecting the auxiliary draft-beam O with one of the central sockets 23 on the main draftbeam. When the implement is to be used for work on a hillside, the right-hand hook 16 is not employed; but in its stead the auxiliary hook 19 is secured to the main blade or shovel A, near its right-hand end, as shown inFig. 1, and the inner end of the auxiliary beam 0 is connected with this auxiliary hook 19, while the forward end of the auxiliary beam 0 is connected with the main beam 0 through the medium of one of the forward sockets 23. The auxiliary blade or shovel A is bolted to the main blade or shovel, and this auxiliary blade or shovel is used only for hillside-grading or to plow out a hillside in the road.

The implement is adapted to be worked by two men, one acting as a driver and the other serving to guide the implement through the medium of the handles 14.

Having thus described my invention, I claim as new and desire to secure by Letters Patent When the implement is to be used 1. The combination of the scraper-blade, a main and an auxiliary draft-beam, means for connecting the auxiliarybeam to the main beam, and means for connecting the rear of the auxiliary draft-beam at different points along the blade, whereby to adjust the said auxiliary beam transversely of the direction of draft.

2. The combination of the scraper-blade, a main draft-beam connected therewith,an auxiliary draft-beam, means for connecting the forward end of the auxiliary draft-beam with the main beam at diflerent points along the main beam, and means for connecting the rear end of the auxiliary draft-beam with the blade at different points along the blade, whereby to adjust said'rear end transversely of the direction of draft.

3. In road-scrapers, the combination, with a blade or shovel, handles connected therewith, draft devices located at the ends of the blade or shovel, a main draft-beam connected with the draft device at one end of the blade or shovel, and an auxiliary draft-beam having adjustable connection with the main draft-beam and a connection with the draft device at the opposite end of the main blade or shovel, for. the purpose set forth.

4. In road-scrapers, the combination, with a main blade or shovel,handles attached thereto, and draft devices located at the ends of the said main blade or shovel, of an auxiliary draft device connected with the main blade or shovel, an auxiliary or extension blade or shovel attached at one end to the main blade or shovel, a main draft-beam con nected with one end draft device of the main blade or shovel and an auxiliary draft-beam having adjustable connection with the main draft-beam and with the auxiliary draft device carried by the main blade or shovel, for the purpose set forth.

5. The combination ofa scraper-blade, a main draft-beam connected with one end of the blade, an auxiliary draft-beam connected with the main beam, a connection for the aux-' iliary draft-beam and blade at that end of the blade opposite to that with which the main draftbeam is connected, and a second connection for the auxiliary beam and the blade at a point intermediate the ends.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses;

THOMAS WILSON.
