GEORGE GREGORY AND GEORGE AUSTIN, OF SKANEATELES, NEW YORK.

ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 250,911, dated December 13, 1881. Application filed July .26, 1881. (No model.)

To all whom it may concern:

Be it known that we, GEORGE GREGORY and GEORGE AUSTIN, of Skaneateles, in the county of Onondaga and State of New York, have invented a new and Improved Road- Scraper, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved road-scraper which can be guided and directed very easily and can be adjusted in its inclination to the road.

The invention consists in a novel construction and arrangement of parts, as hereinafter fully described.

In the accompanying drawings, Figure l is a plan view of our improved scraper. Fig. 2 is a longitudinal elevation of the same. Fig. 3 is across-sectional elevation of the same on the line 00 m, Fig. 1. Fig. 4 is a front elevation of the same, parts being shown in section.

Similar letters of reference indicate correspondin g parts.

In the drawings, the scraper-plateA, which is preferably made of sheet-iron, is provided at its lower edge with a removable scraperblade, B, made of steel. A draft-pole, 0, is pivoted to thejaws D on the front side of the scraper-plate A in such a manner that the plate A will be horizontally inclined'to the pole O, and the braces D and D of unequal length, at the rear end of the pole O; are pivoted to the jaws E E near the ends of the front of the plate A, so that this plate will be held at an angle to the draft-pole. The pole O is provided with a elevis, F, and bolt G, for

' attaching the draft-bar Or whiffletree to the the front apertured end of this rod Linto one of a series of apertures, N, in the draft-pole O.

The operation is as follows: The scraperplate A is inclined more or less to the ground by passing the bolt M through the apertured end of the pivoted brace L and one of the apertures N N in the pole O a greater or less distance from the end of the rod 0, according to the inclination desired. During the operation the scraper is held and guided by the handles K K, which are provided for this purpose. The scraper is held firmly and stiffened by the three braces D, D and L, and cannot be bent out of shape by obstructions that strike against it.

The depth the blade B is to cut into the ground can be adjusted by adjusting the inclination of the scraper,

If the scraper-blade B is dulled, it can be removed very easily to be sharpened or replaced by another blade.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with the scraper-plate A, provided with thejawsD E E and the U- shaped upright H, having handles K, of the draft-pole 0, provided with apertures N, the braces D D of unequal length, rigidly secured to the sides of the draft-pole, the pivoted bracerod L, and the pintle M, substantially as herein shown and described.

2. The combination, with the scraper-plate A, of the hinged draft-bar 0, provided with a series of apertures, N, the U-shaped upright H, the pivoted brace L, and the pintle M, substantially as herein shown and described, and for the purpose set forth.

GEORGE GREGORY. GEORGE AUSTIN.
