WILLIAM HASL UP,

OF SIDNEY, OHIO.

SPECIFICATION forming part of Letters Patent No. 268,666, dated December 5, 1882.

Application filed June 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM 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.

Myinventionrelates to two-wheeled scrapers or excavators.

The object of my invention is to construct a large scraper pivoted and suspended between two carrying-wheels in such a manner that it can be readily filled, dumped, and at the same time carry a large load of earth, the scraper, being suspended on the axles, riding free of the ground when empty and loaded.

Another object of my invention is to utilize the power of the team in dumping and resetting the scraper, all of which will be fully set forth in the accompanying drawings.

Figure 1 is a perspective view of my improvementin position forfillin'g. Fig. 2 is a perspective showing thescraperjn position for hauling a load to be dumped. I Fig. 3 is a perspective showing the position after it isdumped; and Fig.4. is a detached view, on an enlarged scale, of one of the. notched posts.

A represents the body of a scraper of ordinary construction. J represents supporting-posts bolted rigidly to the sides of the scraper.

M represents a tilting frame, to which the scraper is pivoted by means of posts J and pivot-bolts L.

S represents stud-axles rigidly fastened to the frame M bymeans of brackets s and bolts 8.

B represents the ground-wheels which support the scraper.

(J represents the bail by which the scraper is drawn. Itis hinged or pivoted to the scraper by means of bracket N, bolted to the scraper, and provided with stud-pivot n.

H represents handles rigidly secured to the tilting frame M.

E represents lock-rods, the ends of which work in holes pierced in the cross-pieces H and M of the tilting frame and handles.

F represents a crossbar rigidly attached to lock-rods E.

e-represents a spring inserted between the cross-pieces F and H, so as to hold the lockbars in their most forward position.

I represents supporting-posts rigidly attached to the back of the scraper.

t represents notches into which the lockbars are forced by the spring 6, to hold the scraper in position for filling.

'0" represents catches formed in the supports I, which rest upon the lock-rods when the scraper is in position for haulingaload or ready fordumpiug, the supports I below catches r being cut away, so as to allow the scraper to rise in the act of dumping without withdrawing the rods E.

0 represents lugs attached to the sides of the scraper, which rest on the bail and support the scraper in a horizontal position when loaded. The tilting frame M is a sufficient distance outside the scraper to allow lugs c to pass freely in dumping.

It represents a hook-bar pivoted to the tilting frame M, and adapted to engage with the pin 71. on the bail O to hold the scraper inits inverted position, as shown in Fig. 3.

It will be seen that the fulcrum by which the scraper is hinged to the bail is so far forward that the operator has a powerful leverage to control the scraper in loading and to dump it easily when desired.

R. represents a brace-rod extending from side to side through post J, serving to keep the sides from being drawn together by the weight of the load when the scraper is made of sheet metal.

' The scraper is operated in the following manner: When it is desired to load, the lockrods E are inserted in notches t, as shown in Fig.1, thereby rigidly attaching the scraper to the handles H and frame M, the body of the scraper being allowed to turn freely on the pivots a. The operator can readily tilt the scraper to any desired angle forfillini'g. When the scraper is filled the operator elevates the point out of the ground and withdraws the lock-rods E from notches i, and inserts them under the catches i". The scraper is held in a horizontal position by means of lugs a, resting on the bail G. When th load is to be dumped the scraper iselevated by the handles until the forward point strikes the ground, when the draft of the team completes the dumping by the catching of the point on the ground, the scraper A rising off the locks E and swinging through the tilting frame M until itarrives at the position as shown in Fig. 3, when book 71 is made to engage over pin h, it it is desired to hold the scraper in-that position. When it is desired to revert the scraper to its normal position hook it is released; the draft of the team, acting through pivots n L, tips the scraper back to its normal position shown in Fig. 2, rods E being withdrawn to allow the scraper to be received on the catches.

I claim 1. The combination of the scraper A, the tilting frame M, pivotallyconnected at its forward end with the scraper, and provided with axles on which the ground-wheels are mounted,

' the handles H, connected with the tilting frame and connected by a cross-piece, H, the sliding lock-rods E, passing through the tilting frame, and the notched posts secured to the scraper, substantially as described.

2. The combination of the scraperA, mounted on wheels, the pivoted bail O, the lugscon the scraper for resting on the hail, the tilting frame M, pivot-all y connected at its forward end with the scraper, the handles H H, attached to the tilting frame and united by the cross-piece H, thelock-rods E, passing through the cross-piece of the handle and the tilting frame, the cross-pieceF for sliding the lockrods, and the notched posts on the scraper,with which the rods engage, substantially as described.

3. The combination of the scraper A, the pivoted bail O, the pivoted tilting frame M, provided with axles S, on which the ground-wheels are mounted, the handles H H, attached to the tilting frame and connected by the cross-piece H, and the sliding locking-rods E, carried by the cross-piece of the handles and the tilting frame, substantially as described.

4. The posts I, attached to the scraper, and having the notchesiand catches r,in combination with the pivoted tilting frame M, carrying the axles on which the ground-wheels are mounted, thehandles H H, united by the crosspiece H, and the lock-bars E, carried by said cross-piece and the tiltingframe, substantially as described.

5. The combination, with the scraper Aand pivoted tilting frame M, of the hook h, pivoted to said frame, and adapted to engage a pin, h, on the bail G to hold the scraperin its dumped position, substantially as described.

6. The scraper A, provided at its forward portion with stationary posts J,'the tilting frame M, pivoted to said posts, and provided with axles carrying ground-wheels, and the bail O, pivoted to the scraper, in combination with the handles H H, attached to the tilting frame, and united by a cross-piece, H, the lock-rods E, carried by the cross-piece of the handles and the tilting frame, the cross-piece F for sliding said rods, and the notched posts I, secured to the rear of the scraper, substantially as described.

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

V M. HASLUP.
