UNITED sTATES N PATENT oFFIoE.

` C. SGHOFIELD lAND G. J. JOHNS, OF ALBION, ILLINOIS.

SCRAPER.

Specication of Letters PatentNo.

To all whom l? may concern Be it known that we, CHARLES SCHOFIELD and GEO. J. JOHNS, of Albion, in thecounty of Edwards and State of Illinois, have invented a new and Improved Transporting the Formation of Roads and for other Purposes; and we do hereby declare the following to be a full and eXact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l, isa rear elevation, and Fig. 2, a side view of our said invention.

Similar letters indicate like parts in both figures.` i y The nature of our invention consists in so combining and arranging the several parts of a scoop or scraper, as that when the scoop is tilt-ed or tripped, it will revolve suficiently far to allow the earth to slide olf, and then remain in such position, as that the operator, by a slight movement of the handles (which at all times guide and control the machine) in any desired direction, can level down andregulate the quantity of earth or other material to be deposited in any one place, after it has been removed from another, in such manner as to smooth and finish the road or other bank of earth, without the assistance of further labor by To enablel others skilled in the art to make and construct my scraper, I will pro` ceed to describe the same with reference to the drawings.

The beam G, the standard B, and the handles H, H, in shape, and in the manner of uniting them to each other, correspond substantially with similar parts of `a plow.

The scoop A, vis connected to the standard B, and the beam G, in the following manner: the front side of the standard B, is

curved to suit the convex surface of the scoop A, and is faced with a metallic plate C, which terminates in an eye at its lower extremity; a fulcrum pin D, passes through the eye at the lowerend` of C, and its ends are stronglysecured to the convex surface of the scoop A, near its center; tension rods F, F, have their rear ends jointed to the ends of'scoop A, and their front ends are connected to the front end of the beam G, by a strong bolt.

A curved lever E, passes through a mortise in the standard B, and has its front end jointed to the'center of the upper edge of the scoop A; the lever E, has a shoulder on i 7,929, dated February 11, 1851.

its lower edge, which when the lever is drawn back, drops down below the lower end of the mortise on the rear side of the standard B, and holds the scoop in a position to be operated-*the upper or rear portion thereof being pressed againstthe front side of the standard B.

A ring is secured to the rear endof the lever E, which serves to catch and retain the scoop A, in the position shown in Fig. 2.

When the scoop A, has been filled by being drawn forward in the usual manner, it is tilted todischarge its contents, by elevating the rear end, of the lever E, and slightly throwing up the rear ends of the handles H, H; when the scoop A, turns upon its scraping edge, it draws forward the lever E, until the ring at its rear end strikes against the standard B, which will `without any assistance o-r the use of another scraper to finish the road or bank of earth;

the prominent feature in the invention consisting in so combining the severall parts, that the scoop when tripped will stand in the position seen in Fig. 2, A(having turned sufficiently far to allow the dirt to "slide o) `and allow the operator by a slight motion of the scraper at all times `to guide :and control it and thus level down evenly the earth or other material` as heretofore described.

Having thus `fully described our invention what we claim as new and desire to securelby Letters Patent is,-

Thecombination and arrangement of the scoop A, standard B, beam G, arm E, and

handles H, in such manner that when the scoop is tripped, it will revolve sufficiently far to allow the earth to slide o, and then` remain in such position as that the operator,`

by a slight movement of the handles, can level the earth with the scoop, and without the aid of another hand, or another scraper. as herein described and represented.
