SPECIFICATION forming part' of Letters Patent No. 284,647, dated September 11, 1883.

i Application filed May 3, 15583.k (No model.) 4

fo all whom, t may colmar/'1,

Be it known that I, GEORGE D. MATOHAM, of Pittsfield, in the county of Lorain and State of Ohio, have invented certain new and uscful Improvements in Road-Scrapers, andi do hereby declare the following` to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and uscthe same.

My invention relates to improvements in road-Scrapers; and it consists in certain features of construction and in combination of parts that are hereinafter described, and pointed out in the claims.

The object of my invention is to improve and perfect a former invention for whichl obtained Letters Patent No. 234,834, ,dated November 23, 1830, and reissued September 13, 1881.

In the drawings, Figure 1 is a plan view, and Fig. 2 is a side view, of a scraper embodying my invention. Fig. Sis a planview of a circle or ring and the attached straps. Fig. 4 is aside elevation, partly in section, of the rings and other parts of the device in detail. Fig. 5 is a plan view of a sheet of metal from which to form the body of a scraper, cut and in proper shape for bending. Fig. Gis aview in perspective of the body of a scraper that has been made from a single sheet of metal such as is shown in Fig. 5. Fig. 7 is a side view or detail of an iron that is attached to the bail of the scraper.

A represents the body of a scraper, and A a sheet of metal cut into proper shape for bending and forming into such a body. The bail B is pivoted to the sides of the scraper.

C represents stay-bars pivoted to their respective sides of the bail B, and passing through the staples c, at which points they are provided, respectively, with racks for engaging the bottom ofthe staples, asshown, and connected behind the scraper by the bar C', that also forms a handle.

D is the draft-pole or tongue, and D the double-tree that operates between the tongue and the hammer-strap d. Both the tongue and the hammer-strap are slotted, and the hammerbolt dpasses through the double-tree and operates in these slots.

E. represents a pair of rings provided with numerous holes,that register the one ring with the other, and are fastened tothe tongue by means of straps extending forward from the rings and embracing the tongue. These rings are a short distance apart, so that the bail B'inay operate between them, and are held apart in front by the .tongue and on the back side by the thirnble E, that is secured by a bolt passing through it and the rings. These rings are provided with the straps e, that in turn are provided with a hole that is in the center of its respective ring, and through which passes the bolte, that fastens the rings to the bail, and that forms a pivotal point for the rings and tongue, so that the tongue maybe turned i'n either direction until the thimble E encounters the bail.

The tongue may be secured at any desired angle by placing pins z' in the holes i of the rings, so as to embracel the bail when the tongue is in the desired position; also, the pin may be set back in the holes, so as not to embrace the bail B closely, in which case the tongue can vibrate between certain points or angles that may be fixed as desired. justment of parts, by which the tongue can be set at any desired angle, makes it easy to opcrate the scraper in places-such as against banks-where it was diflicult or iinpracticable to operate the ordinary scrapers heretoforein use.

H is an iron that is attached to the top, side, and center of the bail, and has an offset that spans the nut on the bolt e, and has two ears above, between which is pivoted the lever F. This lever is attached at the other end, by the chains f, to the back end of the scraper. To the central part of the lever is attached the chain or link j", connecting it with the doubletree. By reason ofthe slot in th'e tongue and in the hammer-strap, in which the hammerbolt operates, the draft, by means of the chain f', comes entirely on the lever F, and by the lever is distributed in part to the lchains j' and the balance to the bail B.

If desired, the tongue may be removed, in which case the double-tree is still attached to the chain j".

To thebottom and on each side ofthe scraper are attached the runners J. These runners are each made of ,a flat bar of iron attached This adat each end directly to the bottom ofthe scraper, but separated from the scraper through the central part of the runner by one or more thimbles, through which bolts or rivets pass from the runner to the scraper. When the scraper is in a' horizontal position, these runners raise it from the ground and protect it from wear. The forward part of these runners acts also as a fulcrum, by which the cuttingfedge of the scraper may be pried out and disengaged from contact with the ground. l

In operating the scraper the handles G are raised until the edge of the scraper is in position for engaging the earth or' substance to be removed, in which position the racks on the stay-bars are allowed to engageA their respective staples, which said-engagement prevents the scraper from dumping. When it is desired to dump the scraper, by raising the handle C andbreaking the aforesaid engagement of the racks with the staples by means ofthe draft of the chains f on the back of the scraper, the load will be instantly dumped.

A', Fig. 5, represents a plate that has been eut in the proper shape,and slits cut in it, as required, and on which are seen dotted lines that mark the place where the sheet is to be bent. In Fig. 6 is seen the sheet after it has been bent into the proper form and the different parts properly secured to each other.

The body of a scraper made in this manner will be light, cheap, and durable.

What I claim is- 1. In' a road-scraper, the combination, with the tongue having the plates E secured thereto, of the bail pivoted between said plates, and means for adjustably connecting the bail to the plates, and thereby retain the scraper at any desired angle to the line of draft, substantially as set forth.

2. In a road-scraper, the combination, with the tongue and the plates E, provided with straps e and perforations, of the scraperfbail pivoted to the straps e, and locking-pins for securing the scraper at any desired angle to the line of draft, substantially as set forth.

3. In a road-scraper, the combination, with the tongue, plates E, iron H, and lever F, of the bail B, pivoted between the plates E, and chains f and f substantially as set forth.

4L. The combination, with the bail, of the bars C, pivoted at their forward ends to the bail, and provided with teeth or notches on their rear ends, a handle, C', connecting the rear ends of said bars, and staples e, fastened to the scraper-.body, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE D. MATCHAM.
