DlRT-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 320,055, dated June 16, 1885.

(X0 model.)

To all whom it may concern:

Be it known that we, FRANK DUsY and Aswan MCOALL, of the city of Selina, county of Fresno, State of California, have invented an Improvement in a Dirt-Scraper; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to certain improvements in dirt-scrapers; and it consists of a bowl, the front edge of which is adapted to scrape up the dirt and deposit it within the bowl, ends to the bowl having the front formed into arc-shaped runners upon which the device may be tilted and drawn along, connectinglinks by which the end pieces are united to the axle of a pair of wheels situated in front, and chains connecting the same axle with the central portion of the arcs before mentioned, so as to provide adjustable draft for the scraper when turned upon these arcs, and a jointed or divided axle for the wheels, by which the draft, when three or more horses are used, may be equalized, and in certain details of construction, all of which will be more fully described by reference to the accompanying drawings, in which Figure l is a perspective view of a scraper. Fig. 2 is an end section, showing the scraper in position to load itself when drawn along. Fig. 3 is an end view, showing the scraper in position to discharge gradually. Fig. 4 is a view showing the scraper in position to discharge the load at a single point. Fig. 5 is a plan view showing a modification of the axle.

This invention is especially applicable to what are known as dump-scrapers and to what are known as lnick-scrapers. In the dump-scrapers power of the horses is applied to drag the scoop-shaped scraper filled with dirt to its destination, and then, partly aided by the driver, the scraper is upset, leaving its load at a single point. In the buck-scraper power is applied to drag a vertically-placed board or plank along the ground, so that it scrapes dirt in front of it to its destination, where it upsets so as to leave the load.

In our invention A represents the bowl or scoop portion of the scraper, which is of the proper shape to hold the dirt, and is provided with a handle or handles, 0, extending backward from the rear portion. The front edge is of such shape and material that when in the proper position, as shown in Fig. 2, the scraper will take up the dirt as it is drawn along the ground until it is filled.

B B are the ends of the scraper. The ends have their front portion curved, as shown at H, into the form of a circular segment, the arched portion of which projects beyond the front or cutting edge of the scraper, and its lower portion is slightly above the level of the edge, so as not to interfere with its cutting the dirt and loading itself when drawn along. Vhen the scraper is filled with dirt, and it is desired to discharge by raising up the handles, it will be seen that the scraper will turn up on the curved runners ll, more or less, so as to discharge its load, and to hold it in the proper position when it is turned up to dis charge its load. It is connected with the axle D of the pair of wheels E, as follows:

F F are links, the rear ends of which have pivot-bolts securing them to the ends B at a point near their center, while the front ends of these links are connected with the axle D by a sort of clevis or fork, as shown. The front ends of these rods are closer together where they are attached to the axle D than at the rear ends, where they are attached to the ends of the scraper, and as the horses are. attached to the axle by double-trees at points near the ends, this construction will allow one horse or a pair to start considerably before the others without materially changing the position of the scraper, thus keeping it equally behind the team. which is an important point in loading or unloading.

G G are chains extending from the axles to points near the center of the circular arcs H, which are formed at the front of the scraper ends, as before described. These chains are attached to hooks upon the axle, and may be taken up or let out a link or two whenever desired.

The operation of the scraper will then be as follows: Horses being attached to it, and the scraper being held in position shown in Fig. 2, the links F connect it with the axle and act to draw it along when the horses are in motion until it is loaded with dirt, the chains G being in the meantime slack. \Vhen the scraper has reached its destination, if it is desired to unload it gradually, it is done by shortening up the chains, as shown in Fig.3.

ICO

2 szoess The handle 0 is then turned up, thus tilting the scraper until it rides on the curved runners H, and the length of the chain G determines the position in which it will be drawn.

If the chain is short, as shown in Fig. 3, the edge of the scraper willbelifted a little above the ground, and the dirt will spill out gradually and be spread over considerable space, and if it is desired to dump it all at once the chain is let out, as shown in Fig. 4, when the scraper will be drawn farther over, and the draft then comes upon the chain, drawing it upon the runners, the edge of the scraper being so high above the ground that the dirt will be discharged at once. WVhile the scraper is being drawn upon the runners by the chains, the rods or links F, which are flexibly con nected between the axle and the scraper ends, serve as braces to prevent its being turned entirely over upon theteam, and after its load is discharged it may again be turned down into place for another load.

When another team is to be attached, as in some cases, at or near the center of the axle D, the axle may be made in two parts, and a curved yoke, I, may be united to them by means of links or flexible joints at J. If it is desired to support the inner ends of the axles at this point, a wheel, K may be supported upon an axle, L, between the sides of the curved yoke I, as shown. In this case another double-tree, M, would be connected with the front of the yoke, having the usual single trees for the attachment of another pair of horses.

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

1. In a scraper, the scoop or bowl having the ends provided with curved runners on the front portion, wheels and axle to which the draft-animals are attached, links flexibly connected with the axle and extending to the middle of thescraper ends, and chains extending from the axle to the curved portion of the runners, as herein described.

2. In a scraper, the scoop or bowl having ends provided with curved runners at the front, said ends being flexibly connected by links with an axle mounted upon wheels to which draft-animals are connected, and flexible chains adjustable in length extending from the curved runners to the axle, whereby the amount of tilt given the scraper may be'regulated, as described.

3. In combination with the scraper having the ends with curved runners, as shown, the connected chains extending from the runners to the axle of the draft-wheels, and the links or rods flexibly connected with the axle at points nearer to each other than the ends of the scraper to which their opposite ends are connected, substantially as herein described.

4. In a scraper, a wheel-axle to which a scoop or bowl is attached, as shown, said axle being divided in the center and having connecting-yoke I flexibly attached to its adjacent ends, and a means for attaching the draft-animals thereto, substantially as herein described.

5. In a scraper, a wheelaxle having a scoop or bowl connected thereto, as shown, said axle being divided in the center, having its adjacent ends connectcd by a yoke, I, and a supporting-wheel, K, journaled to said yoke, to gether with a means for attaching draft-ant mals thercto,substantiall y as herein described.

In witness whereof we have hereunto set our hands.
