EARTH-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 278,953, dated June 5 1883.

I Application filed September 12, 1882. (No model.) 7

To all whom it may concern Be it known that I, XVILLIAM HASLUP, a citizen of the United States, and a resident of Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Earth-Scrapers, of which the following is a specification.

My invention relates to a twowheeled earthscraper.

The object of my invention is, first, to employ an oscillating crank-axle, on which the supporting ground-wheels journal, and upon the oscillating arms of which axle the scraper is suspended, with levnconnections of the scraper with the crank-axle for raising, lowering, or tilting the scraper by oscillating the axle.

Other objects of my invention will be fully explained in the description of the accompanying drawings, in which Figure 1 is a perspective view of my invention, showing the scraper lowered to rest on the ground, ready for scraping. Fig. 2 is a central longitudinal vertical section of the same in position for hauling a load. Fig. 3 is a similar sectional view, showing the scraper in position when elevated to dump a load. Fig. 4 is a detailed view of the rack and lever devices. Fig. 5 is a-perspective view of a modified form of lever devices.

A represents the body of an earth-scraper; B, the ground or supporting wheels; C, a crankaxle; c, the crank or bent ends, and c the spindles on which the wheels journal.

D D represent ears bolted firmly to the sides of the scraper, and pierced with holes, through which pass the shaft or oscillating part of the crank-axle, so as to pivot the scraper to the axle.

E represents a draw-bail; e, pivot-bolts connecting it to body A of the scraper.

(Z represents astop, preferably formed by bending up thelower end of cars D, and against which the projecting ends of the forked bailhounds E strike to act as stops and hold the scraper level when loaded.

F represents a coupling-reach bolted to the end of the scraper and extending forward and swiveling around the oscillating shaft of the axle C. It is shown made of two parts, with an open space between the parts, so as to afford a firm support for the lifting and tilting lever G, which is journaled in the open or slotted portion of the reach.

Grepresents the tilting-lever, having on its front end a segment of gear, g, and pivoted to reach F by bolt f.

I represents a segmental gear keyed or firmly attached to the arm of axle O, and meshing with gear of tilting-lever G. The preferred form of constructing and attaching these gears is shown in Fig. 4.

H representsa catch engaging over bolt h to lock the lever to hold the scraper-body A in position for carrying or dumping.

K represents a coupling arm pivotally mounted on bolt 9. It is shown made of two parallel limbs united at the front end, and with a hook, k, at its forward end, which engages on the brace-rod S to hold the scraper in a vertical position, as shown in Fig. 3. The fork or throat of the slot or opening in the arm K acts as a stop to limit the forward movement of the lever G and the backward movement of the crank-arms 0, thus regulating the furrow or cut of the scraper.

i represents pin-holes pierced through the arms K, through which a pin may be inserted to regulate the point of stop or movement of lever Gr.

K represents an extension of one of the arms K for releasing or engaging the hook k.

L represents handles bolted to the sides of the scraper A. used, as the scraper is mainly manipulated by means of lever G, handle L being used as an auxiliary thereto, and may in many instances be dispensed with entirely. Vhen the scraper is in the position shown in Figs. 2 and 3 the lever G rests on bolt g, which acts as a back stop to the movement of said lever.

Fig. 5 shows a modified form of lever-connections of the oscillating axle with the scraper body A for raising, lowering, or dumping the same.

-N represents a forked lever pivoted at the front ends of the fork N to the ends of the crank- In practice only one will be arms 0, the fork N. being slotted, as shown, and i scraper is manipulated by the reverse motion of the lever to that shown in the other figures specific features are made the subject of additional clauses of claims.

The scraper is operated in the following manner: The lever G is elevated as shown in Fig. 1, which movement carries the crankarms 0 forward and upward, and, advancing the wheels B, thus-lowers the scraper A till it rests on the ground. The scraper maybe tilted in posi tion for filling by lifting on the lever G; or on one of the handles L. 'When the scraper is filled, the lever G isbrought down and locked in place, as shown in Fig. 2. V hen the load is to be dumped, lever G, locked to the body A, is elevated, the front point of the scraper catches the ground, when the draft of the team will assist in bringing the scraper into the position shown in Fig. 3, and the load is fully dumped. The scraper then may be returned to the position shown in Fig. l. or Fig. 2. as desired.

I claim 1. An earthscraper suspended on two wheels by means of an oscillating crank-axle to which the scraper is swiveled, and having a reach connecting the hail of theaxle with the end board of the scraper, upon which reach the tiltinglever is fulcrunied, substantially as herein set forth.

2. An earth-scraper suspended on a crankaxle and supportingwheels by means of the cars D and reach F, attached to the rear end of the scraper and swiveling upon the arm of the oscillating axle (l, substantially as herein set forth.

3. An earth-scraper suspended and j ournaled upon a crank-axle by means of the ears D and reach F, in combination with a lever, G, fulcrumed 011 said reach and connected to the axle, so that the scraper may be raised, lowered,or tilted by said lever, substantially as herein set forth.

l. An earth-scraper suspended on an oscil-- to the axle and an oscillating lever, G, fulcrumed thereon, in combination with a slotted stoppingarm, K, substantially as herein set forth.

6. In an earth-scraper, the suspendingreach F, and lever G, fulcrunied thereon, in combination with the oscillating arm K, acting as a stop for the lever G, and having a hook for securing the scraper in a vertical position, substantially as herein set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

\VILLIAM HASLUP.
