A hand-lever 11 pivoted point or fulcrum fixed in the hangeris secured upon the bail, which, extending block the draft acts constantly to draw the 5 forward, is adapted to be engaged by a spring forward edge of the pan into the soil, so that latch 12, and thereby secured to retain the with such construction one man may easily scraper-pan in elevated position to'carry its operate the scraper in taking theload.

' I mount standards 21, upon which are mounted spiral springs 22, which springs are connected with the scraper -pan conveniently by a link 23 on the spring engaging an eye bolt 24, secured to the pan. The effect of this construction is that when the pan is let down to take its load'the spring is extended and under high tension, and when the loaded pan is to be lifted the action of the spring facilitates the operation to such extent that one man can easily do the work that without the spring would require the united exertion of two or three men. A further efficient function performed by said spring is to relieve the strain or downdraft on the necksv of the team attached to the scraper, besides and carrying the tongue in this wise. It will be seen that the bail is mounted on the hangerblock in advance of the axle, so that when theload is taken and lifted up the weight of the load, as well as the weight of the men on the platform required tooperate the scraper, is carried on the tongue and bears down upon the necks of the horses. This is a very seriously objectionable feature in this type of scrapers. By providing a connection with the scraper-pan to the rear of the axle, as herein shown and described, the load may be balanced over (or under) the axle to a very great nicety. Said connection is made adjustable by connecting the spring with an eyebolt 25,

passing through an extension 26 on the standard 21 and provided with an adjusting-nut 27. Another important advantage gained by the use of the spring is in'making the dump or dumping the load from the pan. In the usual construction when the dump is to be made the pan is let down; but the greater part of the weight of the load being carried to the rear of the point of suspension of the pan on the bail the rear of the pan, with its load, must be lifted up until the forward edge of the pan is brought into contact with some obstruction sufficiently solid to stop the pan and cause it to turn on its axis. device herein set forth when the pan is let down the tension of the spring will hold up the rear of the pan to such extent and in such manner that a very slight obstruction will be sufiicient to tilt'the pan, thus very greatly facilitating the work of dumping.

If desired,and particularly with the smallersized scrapers, the links 18 may be connected with the bolt carrying the doubletree, as shown in dotted lines in Fig. 6, the tongue in such case being slotted, as shown in dotted lines at 28, to permit movement of the doubletree to accommodate the movement of the With the 4 pan as it is raised andlowered, and thus,

when a'single team is used is gained the advantage of the application of the draft directly to the pan, and the leverage due to the relation of the draft-bars 15 to the bail, as hereinbefore set out.

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

1. In a wheeled scraper of the character described, a bail pivotally mounted in advance of the axle, a scraper-pan pivotally hung on said bail to the rear of its point of suspension, a brace-bar connected with the axle and supporting the rear of said pan, and the draft appliances connected directly to said pan whereby as the draft is applied the leverage of the bail tends to thrust said pan into the soil; substantially as set forth.

'2. In a wheeled scraper having its scraperpan carried by a for wardly-extending bail suspended from the axle, and provided with a brace-bar supporting the rear of said pan, draft-bars'conuected with said pan, and arranged in such manner that as the draft is applied the bail will act to thrust said pan into the soil, substantially as set forth.

3. In a wheeled scraper having its scraperpan carried by a bail suspended from the axle and provided with a brace-bar supporting the rear of said pan,draft-bars connected with said pan, and links connected with said draft-bars for the application of the draft directly to the pan; substantially as set forth.

4. A wheeled scraper comprising the wheels and axle, side bars connected with the axle and carrying the tongue, a platform mounted on said side bars, a brace-bar supporting the axle, a bail provided with a hand-lever suspended from the axle, a scraper-pan hung on said bail, a brace-bar connected with the axle for supporting the rear of said pan, a latch arranged to engage said hand-lever when the scraper is raised up, and the draftappliances connected with said pan whereby as the draft is applied said bail will act to thrust said pan into the soil, substantially as set forth.-

5. In a wheeled scraper having its pan carried by a bail suspended from the axle and provided with a brace-bar connected with the axle for supporting the rear of said pan, draftbars connected with said pan, links connected with said draft-bars, and a draft-rod connected with said links for the application of a snatch-team; substantially as set forth.

6. In a wheeled scraper having its pan carried by a bail suspended from the axle, and a platform carried by side bars connected with the axle, draft-bars connected with said pan, links connected with said draft-bars for the application of the draft, and drop-bars pivotally mounted in brackets secured upon said platform for supporting said draft-bars; substantially as set forth.

7. In a wheeled scraper having its pan carried-by a bail suspended from the axle, a rigid support stationarily mounted on said axle, and a resilient connection between said support and the scraper-pan; substantially as set forth.

8. In a wheeled scraper having its pan carried by a bail suspended from the axle, a rigid support stationarily mounted on said axle and extending rearwardly therefrom, and a resilient connection extending from said support to said scraper-pan at the rear of the axle; substantially as set forth.

9. In a wheeled scraper having its pan carried by a bail suspended from the axle, and provided with a brace-bar supporting the rear of said pan, a resilient connection between the axle and said pan; substantially as set forth.

10. In a wheeled scraper having its pan carriedby a bail suspended from the axle, standards mounted upon the axle and springs connected with said standards and with said pan; substantially as and for the purpose set forth.

11. In a Wheeled scraper having its pan .pan, to the rear of the axle, substantially as and for the purpose set forth..

12. In a Wheeled scraper having its pan carried by a bail suspended from the axle, standards mounted upon the axle, springs connected with said standards and with said pan, and means for regulating and adjusting the tension of said springs; substantially as and for the purpose set forth.
