ALEXANDER L. GRIFFITH, OF BEALLSVILLE, OHIO.
ROAD GRADER AND SCRAPER.
SPECIFICATION forming part of Letters Patent No. 276,393, dated April 24, 1883. Application filed October 31, 1882. No model.)
To all whom it may concern:
Be it known that I, ALEXANDER L. GRIF- FITH, of Beallsville, in the county of Monroe and State of Ohio, have invented a new and Improved Grader and Scraper, of which the following is a full, clear, and exact description.
My invention relates to grading and scraping machines to be employed forroad-scraping, ditching, and for leveling ground generally; audit consists of improvements in the con. struction and arrangement of several of the details of such machines, as hereinafter fully described, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor-' responding parts in all the figures.
Figure lis a perspective view of a grader and scraper as improved by me. Fig. 2 is a plan view, and Fig.3 is a side elevation with a part of the mold-board cut out.
01- represents the landside, and b the moldboard or scraper. I propose to apply ashar'eplate, 0, to the front side and lower edge of the mold-board, having its lower edge, (I, curved forward of the plane of the upper portion, the
said curved portion being wider at the point than the rest and gradually diminishing in width to the heel, and, together with said curved edge, I construct the point of said share in the curved form represented at c, the same being substantially like a gouge with a beveled end, whereby it takes 0d uneven places left in the bottom of the ditch by the plow better and makes the draft lighter, and the greater width of the shareat the point enables it to shear off the strips of the bank left by the plow and pass under the earth better, and also enter it better at the start, besides making the scraper run easier and enabling it to make the bank smoother.
In order to control the direction of the scraper by the draft, I propose to employ an eye or staple, f, located near the point, to bitch on the team when it is desired to have bothsides of the scraper incline alike, or nearly so, to the line ofthe draft; and for gaging it to cause the landside at to run along the furrow to throw the earth to one side only by the mold-board b, I have another hitching eye or staple, g, located at a suitable distance along the moldboard from the point-say about midway between the middle of the mold-board and the to allow the whiffletrees to swing clear of the point of the scraper. These eyes may consist of a rod or bar bent at the center of its length to form an eye, and its ends bent to form eyes,
.and then secured to the board, as shown in the drawings; or separate eyes or staples may be used.
Near the front end of the landside I have arranged a roller, Z, in a lever, on, pivoted to said side at 0, and ranging-along through the guard 19 and over the cross-bar or foot-board q of the frame, where it can be pressed down by the foot of the driver on the arm a to raise the scraper on the roller for loosening up the point when it becomes wedged hard in solid ground and to carry the point around above ground when desired. The lever may be fastened in different positions by the pin t when desired.
Near the rear end of the laudsideis a dished spur-wheel, u, with teeth or spurs v to enter the ground for a guide to control the direction of the machine, and also for a carrier to that part of the machine when not pressed into the ground, which it isintended to be at times, when required, by the weight of an attendant sitting on the spring-board seat 10, provided for the purpose, and also serviceable as a means of lifting up the side a when it may be required for turning the machine and otherwise adjusting it. The wheel a is pivoted to the side of the landside, and its teeth are pointed by beveling them from the opposite side toward the landside, besides beveling them between each other, thus insuring points that will enter the hardest ground to some extent, and such that with the aid of the weight of the attendant on the seat to will insure the running of the board a, on the ground.
The roller 01:, at the rear of the mold-board I), is mounted on a lever, y, pivoted at z, and having a handle, a, extending upward suitably for the driver to raise the mold-board with his right hand at the same time that he raises the point of the scraper by his foot, and
in order to hold it in position to carry the moldboard for a time a ratchet-pawl, I), is pivoted to it to engage the catch 0.
Under the front portion of the landside a, I arrange a shoe, d, of metal, for -a wearingplate, the same being a narrow plate or bar projecting below the edge of the scraper and mold-board to form and run in a groove below the surface scraped over by the scraper.
The yoke e is a rod attached to the landside and mold-board for employment in shifting the machine about by hand.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. vThe combination of hitching-eyes f, g, and h with a scraper, a, 1), eye f being located near the point of the scraper g, midway from said point to the middle of the mold-board and h at the middle of the mold-board, or thereabout, substantially as specified.
2. The combination, with the landside a and the foot-board q, of the spur-wheel u, journaled to the rear end of the landside, and the springseat to, having its forward end secured to the said foot-board and its rear end projecting beyond the landside, substantially as herein shown and described.
3. The combination, with the landside a and mold-board b, of the wheel 1, journaled in the lever m, pivoted to the forward end of the landside, the spur-wheel u, journaled to the rear end of the landside, and the roller w, journaled in the lower end of the lever y, pivoted to the rear end of the mold-board, substan- 5 tially as herein shown and described.
ALEXANDER L. GRIFFITH.
