EA RTH-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 257,773, dated May 9, 1882, Application filed January 20, 1882. (No model.)

To all whom. it may concern:

Be it known that I, PHILIP SMITH, of Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Im provements in Earth-Scrapers, of which the following is a full, clear, and exact description.

The object of my invention is to provide an earth-scraper which shall be light, durable, and of easy draft; and to this end my invention consists principally of a steel blade struck up at the sides to form the body of the scraper, the blade being stiffened and protected by runners secured upon the bottom of the blade, and the end of the body closed and stiffened by an I5 iron or steel end plate having flanges and riveted to the sides and bottom of the body.

The invention also consists in the manner of securing the handles to the body, and of the construction of 'the runners, and of the arrangement and combination of the parts of the scraper, all as hereinafter fully described.

Reference is to be had to the accompanying drawings,forming part of this specification, in which similar letters of reference indicate cor- 2 5 responding parts in all the figures.

Figurel isaperspective view of niyiinproved earth-scraper. Fig. 2 is a sectional elevation thereof, taken on the line 90 w of Fig. 1; and Fig. 3 is a similar view taken on the liney y of Fig. 2.

A represents ablade of steel, whichis struck up to formthe sides B B of the scraper, and 0 represents the end plate, which may be of iron or steel, and which is formed with the side 3 5 flanges,a a, and the bottom flange, b, through which flanges the rivets c 0 pass for securing the end plate to the bottom and sides of the body of the scraper, as clearly shown in the drawings.

40 The runners D D of the scraper are secured upon the under side of the bottom of the blade,

at a suitable distance from the edges of the scraper, by means of the screws 01 01. These screws are preferably inserted from the inside of the scraper, as shown in the drawings, and the openings in the blade through which they pass and enter screw-taps in the runners are countersunk to receive the heads of the screws. By this manner of attaching the runners the endsofthe screws are subject to the same wear as the wearing-surfaces of the blade and the 1 runners, and hence will never project beyond such surfaces nor permit the runners to become detached or loose. The runners are beveled off at their ends, as shown at e a, Fig. 2, and are preferably concaved or have gutters along their under side, as clearly shown in Fig. 3, so

as to form the sharp edges or projections f f, which projections cut into the ground when the scraper is in use and cause the scraper to run steady and prevent it from sliding and sluing around.

The handles E E are secured to the outside of the sides B B of the scraper by means of the staple-plates F F, the points i t of which pass through suitable perforations in the sides of the scraper, and by the bolts g, which pass through the sides of the scraper from the inside, through the handle, and through the staple-plates, and receive the nuts j j outside of the staple-plates, as clearly shown in Figs. 1 and 3. The openings in the sides of the scraper through which these bolts 9 pass are countersunk to receive the heads of the bolts, as shown clearly in Fig. 3. By this means of attaching the handles, should the handles become loose from shrinkage, use, or wear, they may be tightened by simply applying a wrench to the nuts j, which can be easily done, the nuts being upon the outside of the scraper.

The draw-bail G of the scraper may be attached in any suitable manner, preferably by means of the hook-plates h, riveted or otherwise secured in proper position upon the outside of the sides B of the scraper, as clearly shown in Fig. 1.

The runners secured to the bottom of the blade in the manner shown and described not only act as runners to guide, support, and protect the bottom of the scraper, but serve to 0 stiffen and give the requisite rigidity to the blade, and to give sufficient strength to the scraper to enable it to stand all the uses to which such implements are put 5 and the end plate, G,besides olosin g theend of the scraper, 5 serves also to strengthen and stiffen the sides and bottom of the scraper, thus making the scraper efficient for its work and durable, strong, and very light.

Instead of riveting the plate 0 in the scraper with its flanges standing inside or toward the front of the scraper, as shown in the drawings, its position may be reversed so-that its flanges will stand outward, if desired; but the plan shown is preferred,as the capacity of the scraper is not diminished, as it would be if the flanges were turned outward.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An improved earth-scraper, consisting of the blade A, struck up to form the sides B,the end plate, 0, and the runners D, substantially as herein shown and described.

2. In combination'with an earth-scraper,the runners D, guttered upon the under side or conoavcd to form the projectionsff, substantially as described.

3. In an earth-scraper, the combination,with the sides of the plateand the handlesE,of the staple-plates F, provided with points i, entering perforations in the said sides, and the bolts g,

passing through the sides of the blade, the handle, and the staple-plates, and provided with 20 nuts j, substantially as herein shown and described, whereby provision is made for taking up the shrinkage or wear of the handles, as set forth.

4. In an earth scraper, the end plate, 0, formed with the flanges a. and b and riveted to the bottom and sides of the scraper, substantially as described. I

5. The body of the scraper, formed of the steel bladeA and sidesB B,in combination with the 0 guttered runners D D, end plate, 0, and adjustable handles E E, substantially as described.

PHILIP SMITH.
