WHEELED SCRAPER.

SPECIFICATIONforming part of Letters Patent No. 317,279, dated May 5, 1885.

Application filed March 17, 1884.

To all 1072,0172, it may concern.-

Be it known that we, J OSEPH BAILEY and TIMOTHY REBHOLZ, citizens of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in WVheeled Scrapers, of which the following is a specification.

The object of this invention is to construct a scraper suspended between two carryingwheels in such manner that it can be filled with dirt and then raised free of the'ground, hauled to any desired place and dumped, and then again loaded readily.

Another object is to utilize the power of the team which draws the scraper in raising and also in dumping the load without complicated mechanism; and a further object is to raise the scraper high enough to prevent it from draggingif the wheels cut in the earth.

In the accompanying drawings, two sheets, Figure 1 is a side elevation of our improved scraper in position for filling or scraping. Fig. 2 is a view of same loaded and in position for hauling the load to a spot where it may be dumped, and also indicating by broken lines its position when dumping the load. Fig. 3 is a top view of the scraper. Fig. 4 is a view showing the form of the aXle and scraper. Fig. 5 shows the blank, reduced scale, from which the scraper is formed.

The letter A designates ground-wheels, by which the scraper is supported; 13, a large size scraper; O, a crank-axle, the arms a of which partly turn through lever-hubs a and hangers D,which are attached to the crank part c and support the scraper.

E designates hounds attached rigidly to the tongue F, and having their ends I) curved or doubled back and pivoted to the scraper by means of bolts 0, which are riveted to the scraper B, thereby the machine is drawn. The'curved end allows the side bars, d, of the lever G and the eccentric H to pass between the hounds and the scraper when the scraper is dumped; I

The hook-rod I is attached to the tongue, and is in an upright inclined position,so that its hook e may catch on the loop a at the rear end of the scraper, as shown in Fig. 2.

The lever-bar G has two side bars, (I, each one of which is attached to a hub, a. Be-

(No modelJ yond the hub the end of each side bar is bent at an angle thereto, as at d, and on the inner side of the end which is beyond the hub is a projecting lug, (Z which comes in contact with the crank part c of the axle and keeps the scraper from lowering too much or going too deep while filling, as shown in Fig. l.

H designates the flanged eccentric consisting of curved irons attached to the side bars, d. These eccentrics are adapted to increase the leverage when the lever G is up, as in Fig. l, and decrease it when said lever is drawn down, as in Fig. 2. The chainsf, one at each side, rest in the flanged eccentrics, which latter are attached to the side bars by means of a pivot-bolt, g, at one end and a slotted bar, 71, at the other, and is thereby adjustable, so that theleverage may be increased or diminished. The chains f have one end fastened to the side bars, d, and the other end is fastened, and the hounds E are hinged to the bolt 0, and thus raise the scraper.

J designates two handles fastened to the sides at the rear end of the scraper B. A hook, t, isrigidly attached to the scraperback. Pins 75 project one on each side of the scraper, support the hounds, and balance the tongue F, and are adjustable on the scraper, so as to raise or lower the tongue, as desired. A metal loop, a, is rigidly fastened to the back of the scraper, and serves, when the scraper is dumped, to catch in the hook e, as indicated in Fig. 2.

1? represents a drop link or loop hinged on the lever G, and which catches on hook i to hold the lever in a horizontal position when moving the load, as shown in Figs. 2 and 3. A lug, q, riveted on each side of the scraper, holds the crank part c of axle in a veriical position. (Shown in Fig. 2.) A brace-rod, r, connects the two hounds E, and a similar one is on lever-bars d.

By means of the lever G and eccentric H attached thereto the operator has the greatest power to raise the scraper out of the ground, at the same time throwing the weight of the load onthe ground-wheels A and relieving the crank of weight, thereby utilizing the power of the team to turn the crank up and forward, and working in conformity with the movement of team-that is, the leverage or ability of the eccentrics to raise the load decreases as the power exerted by the team increases at the crank c.

The improved scraper is to be operated as follows: When it is to be loaded the operator swings the drop-linkp out of hook z and lowers the scraper B. He then holds the handles J until the scraper is loaded, the lever G meanwhile being up. Then by drawingdown on lever G until the link 1) catches again on hook '5, the load is hoisted, and in a carrying position. Then by lifting on the lever G until the point I) of the scraper strikes the ground, whereupon it will dump and the hook e will catch on loop a and hold the scraper in tilted position, as shown in Fig. 2. When the hook is detached,it will resume its normal position.

The scraper B is formed of a single piece of sheet metal cut-to the shape shown in Fig. 5. The back end of the blank has a slit, 8, at the center, and rivet-holes t are made each side of the slit. This slit facilitates the formation of the bowl part, as thereby it may be pressed into shape more readily. The sheet metal each side of the slit overlaps in the form of a V, as shown in Figs. 3 and 4, and the holes t then coincide, and rivets t are made fast in these holes and secure the parts together.

Instead of overlapping the metal, a V-shaped piece may be cut out of the blank,so as to allow the two edges to abut, and then a separate piece of metal may be placed on the outer side of the bowl across the abutting edges and riveted. I

Either of the above methods make a good back to the scraper, and thereby the same maybe made of one piece of metal.

The scraper is attached to the hanger D by two bolts, u, passing through each hanger. As two additional bolt-holes are formed-in each hanger, (see Fig. 1,) the scraper may thereby be hung higher or lower.

In practice we contemplate using frictionrollers in the lever-hubs a, through which the axle-arms partly turn.

Having described our invention, we claim and desire to secure by Letters Patent of the United States- 1. The combination, as set forth, of a crankaxle, a scraper supported by hangers attached to the crank part of the axle, a lever-bar on g each side of the scraper attached to the axlearm, and means connecting each side leverbar with the scraper.

2. The combination, as set forth, of a crankaxle, a scraper, a lever-bar on each side of the scraper having ahub attached to the axle-arm, and an end, 6., beyond said hub at an angle to the bar, and provided on the inner side with a projecting lug adapted to come in contact with the crank part of the axle.

3. The combination, as set forth, of a crankaxle, a scraper supported by hangers attached to the crank part of axle, a lever-bar on each side of the scraper having a hub attached to the axle-arm, an eccentric-shaped iron attached to each side bar, and a chain resting on each eccentric and having one end attached to the side bar and the other end to the scraper.

4. The combination, as set forth, of a scraper JOSEPH BAILEY. TIMOTHY REBHOLZ.
