EARTH-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 308,372, dated November 25, 1884:.

Application filed January 14, 1884. (No model.)

T0 at whom it may concern:

Be it known that I, CHARLES E. OUTH- \VAITE, a citizen of the United States, residing at Huron, in the county of WVayne and in the State of Michigan, have invented new and useful Improvements in Earth-Scrapers, of which the following is a specification.

My improvements relate to earth-scrapers the body of which is a plank of wood; and the objects of my improvements are, first, to so change the form of said earth-scraper as formerly used as to make it easy to handle when in use, and to adapt it to use in connection with my improved draw-bars; second, by the use of my improved draw-bars and the formation of an edge on the lower side of the body of said scraper-body, at an exact angle of forty-five degrees with the face side of said scraper-body, to reduce the power required to move said scraper when loaded, as well as the labor of handling said scraper when in use, to a minimum; third, by the use of a cuttingedge formed on the under side of said drawbars, to divide sods or other like obstructions when they interfere with the use of said scraper. I attain these objects by means of mechanism illustrated in the accompanying drawings, in which- Figure 1 is arear view of the entire machine. Fig. 2 is a side view of my improved drawbar disconnected from said earthscraper. Fig. 3 is a partial transverse section taken through one of the staples.

Similar letters refer to similar parts in all th figures.

The body of my improved earth-scraper is represented by A, Fig. 1. It is composed of a wood plank from three to five feet long, eight to twelve inches wide, and two inches thick. In the middle of the upperside of A, I attach a board to the handle-supports C C, as shown by B, the upper side of which is shown by b b b. The lower edge of A is beveled backward from the front or face side of A to an angle of exactly forty-five degrees, and the front side should be faced at the lower edge with a strip of iron or steel about four inches wide by one-eighth inch thick. Said bevel is shown by shaded lines F, Fig. 1.

from the end (Z, Fig. 2, an elliptical hole, h,

Fig. 2, oneinchbytwoinches, ismadethrough said draw-bar for the passage of a staple, {1, Fig. 1. Through the straight end of said draw-bar a hole is made, (shown at 7c, Fig. 2,) for the purpose of attaching a team. Faceplates E, Fig. 1, four inches by eight inches by half an inch thick, of iron, are firmly fastened to the back side of said scraper-body, as

shown in Fig. 1. In the center of each of said face-plates a socket or depression is formed one-half inch deep by two inches diameter,

for the reception of the end of the draw-bar d, Fig. 2, when said scraper-is put in position for work, (shown at f, Fig. 1.) A staple made of three quarter -inch round bar-iron with sides four inches long is passed through opening h, Fig. 2, and firmly fastened horizontally into said face-plates, as shown at g, Fig. 1. Said face-plates must be placed so that when the draw-bars D are placed in position over the top of said scraper-body they will clear it it by one inch space. On the under side of saiddraw-bar D, I form a cutting-edge, (shown at H, Fig. 2.) It is about eighteen inches long, and begins just over the top of the scraperbody and runs forward far enough to cut any turf thrown up in loading the scraper.

My improved handle for said earth-scraper is formed of two uprights, two inches thick, three inches wide, and about three feet long, (shown at.C C, Fig. 1.) Said uprights are firmly fastened to the back side of A, Fig. 1, as shown, and a crossbar, I, Fig. 1, two inches square and three to four feet long, is firmly fastened to the tops of said uprights G O, as shown in Fig. 1. Said uprights O O serve also as a support for the board B, Fig. 1, as above described.

I am aware that earth-scrapers made of Wooden plank have been in use for a long 2. A cutting-edge formed on the under side time. I therefore do not claim such a eombiof draw-bars D, as shown at H, substantially nation, broadly; but as set forth, and for the purpose specified.

hat I do claim as my invention, and de- 5 sire to secure by Letters Patent, is CHARLES E. OUTHNAITE.
