DlRT-SC'RAPER.

SPECIFICATION forming part of Letters Patent No. 290,410, dated December 18, 1883.

' Application filed April 24,1883. (No model.)

To all whom it may concern:

Be it known that I, DANIEL A. FAULKNER, of Sacramento, county of Sacramento, State of California, have invented an Improved Dirt- Scraper; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful dirt-scraper for leveling land; and it consists in a peculiarly mounted and suspended bow], and in novel means for dumping it, as will hereinafter fully appear.

The object of my invention is to hold the bowl in position firmly and dump it readily.

Referring to the accompanying drawings, Figure 1, Sheet 1, is a perspective view of the scraper, showing the bowl in position to receive a load. Fig. 2, Sheet 1, is a perspective View of same, showing the bowl in position when dumped. Fig. 3, Sheet 2, is a vertical longitudinal section of same, showing the bowl forced back to its limit to receive a large load.

A is a frame mounted on wheels B in the rear and runners B in the front, though I can substitute wheels in front for the runners when desired.

0 is the draft clevis or link.

D is the bowl of the scraper. This consists of a concaved sheet of metal, which may be suitably braced, and is provided with the usual bit or blade, d. It has sides (1.

E E are front side links or strips, pivoted to the sides of the bowl near their tops and to the sides of the frame A below. The links are jointed near their tops at e.

F F are rear links or strips, pivoted to small lugs f, 011 the back of the bowl at its sides or ends, at points a little below the central horizontal line. Their rear ends are pivoted to the sides of frame A near their lower edges. The frame A has a platform, a, upon which is secured a bearing, G. In this is pivoted a le ver, H, having an end turned at right angles, and provided with curved prongs h.

I represents two arms pivoted to the back of the bowl a little below its central horizontal line and on each side of its vertical center. These arms are curved and converge, and are pivoted in the end of the elbow-lever H to its lower prongh, Fig. 2.

Passing down through the sides of frame A are bolts J, the lower ends of which are formed into or have secured thereto stops or hooks j, which extend inwardly and are adapted to limit the downward movement of the rear links, F, Fig. 3. These bolts have nuts K on top.

The operation of the device is as follows;

I/Vhen the lever H is in a vertical position, the arms I extend upwardly and backwardly, the rear links, F, are nearly horizontal, and the front links, E, are inclined rearwardlyto their joints 6. This throws the bowl into position for receiving a load, Fig. 1. In this position the strain against the bit is in a line directly against the rear links, F, and the bowl cannot be forced back. The weight of dirt as it fills the bowl, bearing down upon and against its upper portion, further insures its firmness. To dump the bowl the lever H is drawn back to a horizontal position, Fig. 2. This movement has the effect, first, of raising the bit from the ground, and then of drawing the whole bowl backward, and at the same time turning it to a vertical position. The bowl turns on its front and rear links as pivots, and its movement has the peculiar advantage of not merely turning to allow the dirt to fall out, but of withdrawing itself from it. The jointed front links, E, permit a free movement. The dirt falls out from the bowl when in this vertical position, and the bit of the bowl is raised high enough to scrape or level the dirt as the device proceeds. The object of the stops or hooks j is to enable me to regulate the bowl, as to position, to take a light or heavy load. WVhen the bolts J and stops j are lowered by releasing the nuts K, the bowl may be turned nearer to a horizontal, to receive and carry a larger load. This is done by throwing the lever H beyond a perpendicular. Its upper prong h, fitting over the front edge of the bowl, forces it down until the rear links rest in the stops or hooks, Fig. 3. Now, by adjusting these stops higher up it will be seen that the rear links, F, will meet them sooner and prevent the bowl from moving as far toward a horizontal as before. Accordingly it cannot take as large a load. Thus the device may be regulated to do such work as may be desired, making it adapted for two or more horses.

The mechanism is simple and easily operated, rendering the device an efficient implement or machine for leveling or scraping land.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a dirt-scraper having a frame, the front side links, E, the rear side links, F, and the bowl D, standing between said links when in an operating position, in combination with a means for turning said bowl on said links, substantially as herein described.

2. In a dirt-seraper having a frame, the front side links, E, the rear side links, F, and the bowl D, standing between said links when in an operating position, in combination with the elbow-lever H and the arms I, substantially as herein described.

3. In a dirt-scraper having a frame, the bowl D, the front side links, E, jointed at o, and the rear side links, F, arranged as shown, in combination with the elbmf-lever H and the arms I, substantially as herein described.

4. In a dirt-scraper having a frame, A, the bowl D, the front side links, E, and the rear side links, F, in combination with means for turning said bowl on its links, and a means for limiting its movement, consisting of the vertically-adj ustable bolts J, having stops or hooks j, with which the rear side links are adapted to engage, substantially as herein described.

5. In a dirt-scraper having a frame, A, the bowl D, the front links, E, and rear links, F, in combination with the means for turning said bowl, consisting of the elbow-lever II, having prongs h, the upper one of which fits over the rear top edge of the bowl, the arms I, pivoted to the lower prong, and the means for limiting the movement of the bowl, consistingof the vcrtically-adjustable bolts J, having stops or hooksj, all arranged and operating substantially as herein described.

In witness whereof I hereunto set my hand. 40
