UNITED STATES PATENT OFFICE.
REUBEN W. OLIVER, OF EAST AURORA, NEW YORK, ASSIGNOR TO R. W. OLIVER AND H. HOYT.
ROAD-SCRAPER.
Specification of Letters Patent No. 13,810, dated November 13, 1855.
To all whom it may concern.'
Be it known that I, REUBEN WV. OLIVER, of East Aurora, in the county of Erie and State of New York, have invented certain new and useful Improvements in Road- Scrapers, which I have described in the following specication and illust-rated in the accompanying drawings with sufficient clearness to enable others of competent skill to make and use my invention.
The nature of my invention consists in, first, supporting the forward end of the scraper upon two adjustable levers each of which levers has hung upon it a wheel which wheel acts as a fulcrum for the lever, said levers extending to a position back of the scraper to be conveniently operated, and the back end of the scraper resting upon a xed bearing as hereinafter set forth; second, in hanging the bottom of the scraper to the sides in such a manner that the back edge of it will when a catch that hooks it is released be forced down by the weight of the load and thus allow the dirt to escape, and, third, in causing the bottom of the scraper to assume its place for loading with certainty by connecting it to the levers above mentioned as hereinafter described.
In the accompanying drawings, Figure 1 is a-side elevation of my improved scraper in the proper position for moving it from place to place or carrying the dirt away when loaded. Fig. 2 is a. plan of the same. Fig. 3 is a side elevation with the parts in the posit-ion for loading. Fig. 4L is a sectional elevation of some of the parts, showing more clearly the bottom of the scraper and the catch which holds it.
A is a caster wheel which supports the back part of the scraper. It is hung on a bearing O which turns in a socket N attached to the back D of the scraper.
B, B are the front wheels. They are hung to the'levers F, the outer bearing being supported by brackets G attached to the levers F for that purpose. The sides C of the scraper are hung to the levers by bearings R. The levers F are connected together at the back end by a cross bar H.
Q Q are loops to draw by.
E is the bottom of the scraper strengthened by iron bars running lengthwise of the scraper. Said bottom terminates as usual at t-he forward end in the iron M.
The scraper as before stated is represented in Fig. 3 in the position for loading. When it is filled, the cross bar I-I is pressed down so as to raise the forward end of the scraper and bring the parts to the position represented in Fig. l in which position they are held by the catch J which is attached to the back of the scraper, catching upon the bar H for that purpose. The end of this catch J is kept in place and guided by the staple I and kept from being drawn out of this staple by the pin T.
rIhe operation of dumping is performed by lifting the lever K which unhooks the spring catch L, which holds up the back end of the bottom E. This bottom is hung on a bearing at S to the draft loops Q, and being free to turn on this bearing, the weight of the load being principally behind the bearing presses the back part of the bottom down as soon as the catch L is removed and allows the dirt to escape. The rod which forms the bearings at S must extend across the scraper and be riveted or otherwise secured at each end to keep the sides C from spreading apart. When the dirt has slid olf the bottom, the weight of the iron M will in ordinary cases bring the bottom back to its place, but to provide against its failing to do so, in muddy or past-y ground, I attach one end of a chain P to each back corner of the bottom E, and the other end of these chains I fasten to the levers F, so that when the back end of these levers is thrown up to place the parts in a position for loading, the weight of the scraper upon the forward end of the levers will draw the bottom E up to its place. A
I do not claim making the height of the scraper adjustable upon a frame supported upon wheels, as this has already been done, but
I claim- 1. Supporting the forward end of the scraper upon levers which rest upon the wheels B or their equivalent, as a fulcrum and extending back of the scraper for the purpose of operating conveniently the back end of the scraper resting upon a fixed support as herein set forth.
2. I claim hanging the bottom of the scraper to the sides as herein set forth.
3; I claim securing the return of the bottom E to the posit-ion for loading by the chains P or their equivalent attached to the said bottom M and to the levers F as herein set forth, or in any other manner substantially the same.
REUBEN W. OLIVER.
