WHEELED SCRAPER.

SPECIFICATION forming part of Letters Patent No. 694,561, dated March 4, 1902.

Application filed September 7:1901. Serial No. 74,687. (No model-l i To aZZ whom it may concern.-

Be it known that I, WINFIELD 'S. LIVEN- GOOD, a citizen of the United States, residing at Kansas City, in the county of Jackson, in the State of Missouri, have invented certain new and useful Improvements in Wheeled Scrapers,of which the following is a full,clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention relates to certain new and useful improvements in wheeled scrapers, having more particular relation to the application of the draft appliances to the scraperpan and also to the construction and arrangement of the brace-bar by which the rear of the scraper-pan is connected with the axle. I-Ieretofore in scrapers of this type in which the scraper-pan is hung'by a bail from the axle the draft-bars have been connected with the axle in such manner that the draft is applied to the axle and thence through the bail to the scraper-pan. In such construction when thescraper-pan is let down to take its load it hangs at a considerable distance below the axle and below the point of direct application of the draft, and the point of connection of the bail with the scraper-pan is to the rear of the point of application of the draft. The draft is thus applied at a very great disadvantage and has no tendency or at most very little tendency to draw the scraper-pan into the soil. It hence requires very arduous labor on the part of the operator, usually two men being required to hold the scraper-pan in position to take its load. With my improvements by connecting draftbars with the bail in such manner that the draft is applied directly to the scraper-pan and in such relation that the scraper-pan is drawn into the soil, whereby the arduous labor is very much relieved, in so much, indeed, that one man may easily operate the scraper, even to the extent of causing the pan to enter the soil below where it may have been previously plowed,-which before could scarcely be done by two men.

To accomplish this and other objects, as will appear, my invention consists in certain features of novelty hereinafter described, and set out in the claims.

Figure 1 represents a plan view of a wheeled scraper embodying my invention and improvements. Fig. 2 represents a plan View, somewhat enlarged,0f ascraper, partly broken away, showing more in detail the draft appliances and the folding rear brace-bar. Fig. 3 represents a side elevation showing the draft appliances from the inner side, the View being taken substantially on the line as a; of Fig. 1. Fig. 4 represents a side elevation of the scraper. Fig. 5 represents adetail view showing the manner of connecting the draft appliances with the scraper. Fig. 6 represents a detail View of the hanger by which the bail and push-bars are supported from the axle.

Similar numerals refer 'to similar parts throughout the several views.

1 represents the wheels, and 2 an arched axle of the usual construction. Upon said axle are mounted hanger-blocks 3, carrying a hanger 4, which are formed by forwardlyextending arms 5, 'on which are provided pockets 6 by inner flanges 6. In said pockets are seated the push-bars 7 and the bail 8, said push-bars being rigidly secured to said "arms 5 and said bail being pivotally mounted in said pocket. By this construction a very great advantage is gained in that in the usual construction the bail and the bars 7, which in 'such usual construction are the draft bars, are connected to the arm simply by passing bolts through the same and through the arms 5, an'dsaid bolts not being supported at the inner ends the weight and pull of the scraper when at work tends soon to loosen the bolts and cause objectionable loosening and disorganization of the parts, While by seating the bail and bars in the pocket and.

ICO

Upon said yokes are mounted the draft-bars 13, the point of connection of said draft-bars with the yokes being to the rear of the pivotal point or fulcrum of the bail on the hangers,the relation being such that as the scraperpan is let down to take its load said point of connection will pass from above to below the fulcrum of the bail, and as the loaded scraper is raised said point will pass from below to above the fulcrum. The efiect of this is that when the scraper is let down to take its load the draft being exerted on the bail between its fulcrum and the scraper-pan acts with a very great leverage to draw the pan into the soil, so much so that it will cut into and enter the soil below where it has been previously plowed, cutting to some depth below the level of the wheels, as shown in Figs. 3 and 4.

The draft-bars are connected with a draftbeam 14, suspended by links 15 from the platform, and said draft-beam is connected by draft-rods 16 with the doubletree 17, which is carried upon a bolt 18, which works in a slot 19 in the tongue, so that as the scraper-pan is raised and lowered the doubletree is permitted alongitudinal movement to accommodate the movement of the pan.

The bail is provided with the usual handlever 20, by which the scraper-pan is raised and lowered, and the usual spring-catch 21 is mounted upon the platform and arranged to engage said lever to retain the scraper-pan in elevated position. In Fig. 3 the parts are shown in heavy lines with the pan lowered to take its load and in dotted lines with the pan elevated to carry its load.

A brace-bar 22 is provided between the axle and the platform to retain the axle in vertical position.

The rear of the scraper-pan is supported by a folding brace or stay-bar of peculiar construction, consisting of a bar 23, pivotally mounted between ears 24 on the pan, and bars 25, pivotally connected with the axle, said bars being hinged together at 26, so that when the scraper-pan is turned up in position to travel upon the road said bars will be folded together, as shown in Fig. 4, a book 27 being provided and arranged to engage the rod 36 at the rear of the pan upon which the bar 23 is mounted and retain the pan in position when turned up, said rod also extending beyond the ears to form a handle 36, by which the rear of the pan is lifted up. An extension 28 is provided upon the bar 23, and a stirrup 29 is mounted upon the bars 25 and arranged to be turned over said extension and lock the bars against folding when the scraper-pan is carried in operative position, as shown in Fig. 3.

Upon the axle between the hanger-blocks 3 and the wheel-hubs are mounted caps 30, bearing against said blocks and provided with sleeves 31, embracing the axle and having lugs 32 at the outer ends, and caps 33, bearin g against the wheel-hubs, are provided with sleeves 34, telescoping said sleeves 31 and having a recess 35, arranged to be engaged by said lugs, whereby is provided a very convenient and effective construction to retain the Wheels in proper position upon the axle.

The draft being applied directly to the scraper-pan, it is manifest that the wheels and axle or frame of the machine are pushed forward by the connection of the bail with the push-bars 7.

Having thus fully described my improvements, what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a wheeled scraper having its pan carried by a bail suspended from the axle, the draft appliances connected with said bail, whereby the draft is applied with a leverage upon said bail to draw the pan into the soil in taking its load; substantially as set forth.

2. In a wheeled scraper havingits pan carried by a bail suspended from the axle, yokes on said bail, and draft-bars connected with said yokes and with the doubletree; substantially as set forth.

4. In a wheeled scraper havingits pan carried by a bail suspended from the axle, yokes having their ends mounted upon said ball upon opposite sides of the point of suspension, and draft-bars connected with said yokes and with the doubletree, and arranged in such manner as to pass the point of suspension as the pan is raised and lowered; substantially as set forth.

5. In a wheeled scraper having its pan car-' ried by a bail suspended from the axle, the combination substantially as described, of the push-bars connected with the axle and with the scraper-tongue,a platform mounted thereon, a draft-beam suspended by links from said platform, yokes mounted upon the bail, draftbars connected with said yokes and with said draft-beam, a doubletree slidably mounted upon the scraper-tongue, and draft-rods connected with said draft-beam and with said doubletree.
