ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 481,160, dated August 23, 1892.

Application filed September 28, 1891. Serial No. 407,070. (No model.)

T0 a/ZZ whom it may concern.-

Beit known that I, JAMES M. BROOKS, acitizen of the United States, residing at Melena, in the county of Pike, State of Georgia, have invented certain new and usefullinprovernents in Road-Scrapers, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation showing the scraper ready for loading. Fig. 2 is a top or plan view. Fig. 3 is a side elevation showing the scraper loaded, 'and Fig. 4 is an enlarged detail showing the devices for locking the scraper-pan in position when loaded.

My invention relates to road-Scrapers, and more particularly to that class of scrapers in which the scraper-pan is carried 011 wheels and is adapted to be loaded by scraping the earth and is then used for transporting the earth to any point whore it is desired to dump it.

The principal object of my invention is to provide new and improved devices for supporting the scraper-pan and for holding it in a horizontal position when loading, so that it will not readily tilt if it should strike an obstruction.

Another object of my invention is to provide improved devices for retaining the earth in the scraper after it has been loaded, s0 that it may be carried any desired distance and over more or less rough roads without danger of losing its load. I accomplish these objects as hereinafter speciiied, and as illustrated in the drawings.

That which I regard as new will be pointed out in the claims.

In the drawings, 1 indicates wheels which are used to carry the scraper pan, which wheels may be either of wood or metal, as desired. They are journaled upon spindles 2, which are mounted upon the ends of an arched axle 3, as best shown in Fig. 2.

4 indicates the operating-lever,which is connected by means of arms 5 to the arch of the axle 3, as best shown in Fig. 1, the arms 5 being rigidly secured to the arched axle at about right angles to it, as shown. The arms 5 extend a short distance forward of the arched axle, forming extensions 6, to which various other portions of the lifting mechanism are secured. The extensions 6 are preferably curved upward at their ends, as shown.

7 indicates the scraper-pan, which may be of any desired pattern and is preferably made of steel, having a cutting-edge at its front end. The pan 7 is open at the front, so that it will be adapted toscrape .up the earth as it is moved forward.. The pan 7 is supported by means of standards 8, one of which is rigidly secured to each side of the pan 7 and projects upward and is pivoted at its upper end to the extension 6 of one of the arms 5, as best shown at 9 in Fig. 1. The standard 8 is of such length that when the lever 4 is raised to the position shown in Fig. 1 the scraper-pan will rest upon the ground. Then the lever 4 is depressed to the position shown in Fig. 3, the arched axle 3 will be turned into a position more nearly in a vertical line with the spindles 2 and the standard 8 and pan will be elevated.

In order to support the rear end of the scraper-pan, it is provided with a lug 10, which is adapted to be engaged by a hook 11, which is pivoted at such a point to the lever 4 that when the lcver is depressed the hook will engage the lug 10. A handle or arm 12 is provided upon the hook 11, whereby the hook may be thrown out of engagement with the lug when it is desired to raise the lever.

Instead of lugs, other suitable stops may be used.

13 indicates a draft-bail, the ends of which are connected to the scraper-pan at opposite sides, as best shown in Fig. 2. The front of the bail 13 is connected to asuitable tongue 14.

15 indicates bars, which are pivoted at their lower ends to the scraper-pan 7, one being` placed at each side of the front end of the pan and on the outside of the pan. Each bar 15 is provided at its upper end with a hook 16, and each bar is made of such length that its hook 16 will be upon alevel with or slightly higher than the arm of the draft-bail 13, which lies next to it. In order to prevent the bars 15 from being bent out of their proper position, they are placed between the side portions of the draft-bail and the side of the scraperpan, as best shown in Fig. 1.

17 indicates lugs, which are secured to the draft-bail, one being placed at each side in IOO such position that it will be adapted to be e11- gaged by the hooks 1G upon the upper ends of the bars 15, as best shown in Fig. 4.

18 indicates straps, one of which is placed at each side of the scraper-pan, each of which straps is connected at one end to the upper end of one of the bars 15 by pivots 19, and at its other end is pivoted to the end of one of the extensions i3 of the arm 5. By this construction when the lever 4.- is depressed the upper ends of the straps 18 will be raised, throwing' back their lower ends and the upA per ends of the bars 15, thereby disengaging the hooks 16 from the lugs 17. The straps 1S are of such length that when the scraper-pan is resting on the ground in position for loading they will hold the hooks 16 on the upper ends of the bars 15 in engagement with the lugs 17. Tilting of the scraper-pan while it is being loaded will thereby be prevented, as the hooks 1G will then be in engagement with the lugs 17 and the bar 15 ,and standard S will act together to hold the pan 7 in a horizontal position.

21 indicates a sheet-metal hood, which is so shaped that it is adapted to fit over the front end of the scraper pan or box to close that end, so that when the scraper is loaded the dirt will he prevented from spilling. The hood 2l is pivotcd by means of straps 22, se` cured to it at its upper edge, to the sides of the pan 7, the straps 22 being preferably pivoted to the sides of the pan upon the lower portion of the standards 8. The rear portions of the straps are adapted to lie outside of the draft-bail and parallel with it when the hood 21 is lowered, and the forward portion of each of said straps is bent inward and slightly upward, so that the hood 2l will move within the draft-bail and will be supported by it, as the straps 22 will rest upon the upper edges of the draft-bail, as best shown in Fig. 3.

23 indicates connecting-rods, one of which is secured at its lower end to each strap 22 at a point between the pivot of the strap and the hood 2l, and at the other end passes through a hole in a lug 24C, cast or otherwise secured upon the inner portion of the axle 3, near the spindle 2. The rods are adapted to move freely in the holes through which they pass, and are prevented from passing out of said holes by means of nuts or caps 25, which are secured upon their ends. The forward ends of the rods 23 are preferably forked, as shown in Fig. 2, to embrace the straps The rods 23 are of such length that when the lever 4: is raised to the position shown in Fig. 1 the hood 2l will be raised sutliciently to expose the front end of the pan 7', so that the pan may be loaded. The nuts or caps 25 will then bear upon the lug 21 and the weight of the hood will then be supported by the rods 23. Then the lever 4 is depressed to the position shown in Fig. 3, the scraper-pan will be allowed to swin g backward sufficiently to allow the hood 21 to descend to the position shown in Fig. 3, when it will close the front portion of the scraper-pan. lVhen the hood is in the position shown in Fig. 3, the lugs 24 will lie closer to the point where the rods 23 are connected to the straps 22, and the rods will therefore move backward through the holes in the lugs 24 suiliciently to permit the hood 21 to rest in the position shown in Fig. 3.

2G indicates the usual front hook, which is pivoted at its lower end to the rear end of the tongue 14 and extends upward and backward and is adapted to engage a lug 27 on the rear end of the scraper-pan to hold the pan in a more or less perpendicular position when it is being returned for another load after being dumped.

2S indicates the usual handles on the rear end of the scraper-pan, by means of which the pan is operated.

In loading the scraper-pan the lever 4 is raised to the position shown in Fig. 1 and the pan will rest upon the ground and the hood 21 will be raised to expose the front of the scraper, as hereinbefore described. After thc scraper has been loaded the lever -lis depressed until the hook 11 engages the lug 10. The scraper-pan will thereby be raised from the ground sufficiently so that it will swing free from the ground andthe hood 2l will be lowered so that it will close the frontof the scraper and will be in the position shown in Fig. 3. The load may then be carried any desired distance, as the hood 2l will effectually prevent it from spilling.

'lhe scraper is dumped in the usual manner by raising the lever t until the front edge of the scraper-pan engages the ground. The scraper will then be drawn to an inverted position by the team. The hood 21 remains supported by the draft-bail as the scraper is dumped and while the pan is in an upright position, and is returned to its elevated position when the pan is lowered to a horizontal position and the lever 4 is raised, as hereinbefore described.
