EXCAVATING ANDGRADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 360,539, dated April 5, 1887.

Application filed December 2, 1885. Serial No. 184,412. (No model.)

To all whom it may concern:

Be it known that I, EDOUARD REMILLARD, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Improvement in Excavating and Grading Machines, of which the followingisaspecificalion.

My invention relates to improvements in excavating and grading machines; and it consists in the construction and arrangement of machinery, as hereinafter described, for operating scrapers to elevate earth and discharge it automatically either into cars or through chutes to form embankments. It will be readily understood by reference to the ac companying drawings and the letters referring thereto.

Figure 1 is a side elevation of my inclined earth-elevator with the scraper and draft-cable; Fig. 2, a plan View of the same; and Fig. 3, a perspective view of the same,with the anchor and endless wire rope and machineryfor moving the scraper backward and forward.

A represents the main frame; B, the endless wire rope; G, the scraper; D, the anchor;

draft beam P is held in a rigid position on either side of the anchor by means of a pin, P, which passes through openings in the bifurcated lugs I, arranged on both sides of the anchor.

In some cases the scraper may be operated directly by a single draft-rope carried over suitable sheaves for the purpose, as in Figs.

1 and 2 but in such case the scraper will have to be drawn back for a new load, either by hand or by hitching a team to a rope or chain (not shown) attached thereto.

The following is the construction of the same: I construct the frame A of timber, and the fioor K of any suitable flooring, and cover with such metal strips as will form a good draftway for the scraper C to slide freely upon as it is drawn up the incline. I form the scraper about in the form of the common road-scraper. I construct the rope B of wire similar to other wire rope.

I do not confine myself to any particular mechanism for operating the draft-rope, as animal power or any well-known mechanical power may be employed to draw the scraper backward and forward. I employ any wellknown anchoring device for the outer portion of the cable, so that it allows the scraper to be drawn back the required distance in every part where the excavation is required. The ground may be prepared for scraping by plowing in the usual way, where light work is to be done, although for heavy and rapid work I employ heavy. plows of any required dimensions and operate them by the cable or wire rope.

The following is the operation of the same: In making an excavation the machine is set at a convenient point on the side of the excavation, and the wire rope B is anchoredback over the excavation, so as to allow the scraper to be drawn back to the opposite side of the cut or excavation. As it is drawn forward to the machine, it is dipped and filled in the usual way and drawn up the incline K until it projects over the top of the same. The front of the scraper 0 falls down into the position shown by the dotted lines in Fig. 1, the point passing under the roll L and sliding down the stops N while the rear part of the scraper is raised, thus turning the same bottom upward, and discharging all the dirt through the discharge-opening 0 into a cart or other vehicle, or through any chutes or inclines to fill depressions or form embankments. The upper roll or rest, M, holds the scraper in line and allows it to slide freely while it is drawn down over the roll L, over which it partially revolves, and is turned right-side up and drawn backward down the incline K and out in posi tion to take another load.

In order to render my excavator more portable, I either attach bearing-wheels or place it upon any suitable trucks, according to the situation or condition of the ground.

2. The combination, with a supportingframe, of journaled rollers L M, the guides N N, a scraper, an anchor-sheave connected with the frame and anchor, and a rope secured to the anchor and passing over said sheaves, substantially as set forth.
