rMPRovni ROAD-SCRAPER.

The Schedule referred to in these-Letters Patent and making part 0f the Same' To all whoi'n it ana/y concern:

Be it known thatI, JAMES F. Wlsonnnn, of Springfield, in the county, of Clark, and State of Ohio, have invented certain new and useful improvements in Road- Scrapers and I do hereby declare that the following is t a. full, clea and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to Jcholet-ters of reference marked thereon, like letters indicatingxr like parts where# ever they occur. .l y

To enable others skilled in the art to construe f use my invention, I -will proceed to describe it.

My invention consists in a novel construction of a sciaper for moving earth, usually denonihlated a roadscraper, as hereinafter explained.

Figure l is a perspective view,

Figure 2, a side elevation, and

Figure 3, a bottom plan view of myiinproved scraper.

In making my improved device, I construct the scraper proper with a bottom, A, and sides, B, as represented in the thawings, the sides being` made circular on their upper and rear edges, as shown in fig. 2..

About midway of the sides, I form a journal, c, by which the body of the scraper is pivoted to a frame,

consisting of two side-bars, C, united by a cross-bar, T

and a rod, F, which latter serves as a handle for holding, guiding, and operating the scraper.

To form the bearings or boxes for the journals c, I cut a circular notch in the lower corner-of the bars C, and then secure them therein by means of a met-al strap, a, which passes around the end of the bar C, and is fastened thereon by a bolt, passing through the bar Y (l and both ends of the strap a', which latter thus serves not only to hold the j cin-nals in place, but also to prevent the end ofthe bar C from splitting` or becoming injured.

Upon oneof the sides, B, I attach securely an inclined stop, -i, near the front, and, near the rear, two similar stops, m. and n, Iset iu opposite directions, with a space between these latter, sutiicient to receive and hold the end of a lock-bar, D, pivoted to the under side of the-bar C, as represented in iig. 3.

A spring, Z, is applied to the bar l), iu such a manner as to cause it to press inward, and lockagaiust thc stops 7i, or -m and ylaas the scraper is revolved on itsjouruals, and thus to lock the frame rigidly to the scraper.

The stops m and ln maybe made separately,- and secured b v bolts, or they may both be made in one piece,with n notch at the cent-re, ibrthebar I) tolock into. In either ease, the) shouldbe made adjustable, by means oi' a slot or a series ot' holes, so that the angle of the frame or handle may be adjusted as desired, to adapt it to be used conveniently by persons of different heights; and they should be set dia'lgonallly, or one in advance ot'thc other, on the side-plate B, so as to prevent the possibility of a stone getting between them, and preventing the lockinglbar from operating, as might be the rase if they `were placed diri-.etly opposite each other.

A chain or cord, E, is attached, at one end, to one ofthe bars (l, and at its opposite end 'to the lock-bar 1), so that, by pullingr on said chain, the lock will be released, and tlul scraper permitted to turn on its journals, while the frame is held in position.

A bail, is attachedtothe journals, as shown in fig. 3, for attaching the team.

.By this construction, it will be seen that I produce a scraper that can bc operated with ease a-nd rapidity. The operator can sta-nd erect, and having the long, frame for a handle, can raise or depress the front of the scraper with far greater ease and facility than when constructed in the usual manner.

By making the sidcson a circle, as shown, it will be seen thatI the scraper, when turned upside down, as shown in red in iig. 2, as it must; be to empty its contents, will rollover as soon as the lock-bar D is released from the stop i., which is simply to hold it in that position while beinr drawn along empty.

As it tlms rolls over, the bar I) will automatically lock against the stops lmv il, and thus hold the frame rigidly in position, while the scraper is being iilled and moved along.

Not only can it be operated'with much greater ease and eiiiciency than the ordinary kind oi'seraper, but the handles are kept from being soiled, as they need never touch the ground.

Having thus described my invention,

1. lhe pivoted lever l), in combination with the frame, arrimged to lock against the stops in, 92,' and li, and provided with the chain E for operatingl it, substantially as described.

2. The stops m, n, and arranged to operate as de scribed, for the purpose ot' holding the scraper in the different positions, as set forth.

3. Providing, the scraper. with tle adjustable stops for adjusting,- the handle at various angles or heights, substantially as and t'or the purposes set forth.

4. 'lhe manner o1l securing,r the frame to the scraper, by means ofthe notch in the corner of the bars (flA and metal strap a, arranged as described.
