' Thesubject of my invention is an improved method of, and machine for, cultivat y ing land.

According to the'new process the ground is mechanically scraped by means of suitable implements, and the soil so scraped is thrown upward." 4 r Thefnfiachine for carrying out the process is furnished with ari-endless" apron, which can be set in motion by ineansof la motor, employed to drive the machine. On' this apron' the operative implements are disposed insuchrman'n'er that-"they can yield in all diY- rections. f l

Certain practical embodiment-tact the invention are illustrated in the accompanying drawing. I r

,Figure 1 is an elevation, showing one torni of constructionof the machine, such parts as are not necessary for explanation ot the inventionvbeing omitted. Fig. 2 is a plan of the 'left-hand portionot' Fig.v 1, a part of the apron being broken away to display underlying parts. Figl is a vertical see tional view illustratinga modified construction of drum withv sieveJf-F ig. i is a front, view of a sinuous sieve. Figs. 5-9a show various forms of implements. Figs. 10-15 illustrate several forms of construction of the endless apron. Fig. 16 illustrates diagramrnatically two ways of disposing the implements upon the endless apron..

Referring to Figs. 1 and 2, there are provided at each side of the traine 1 'of a motorcart-bars 2' whose .upper endsare journaled on the pins 3, while the other endsare connected by a shaft 5. On the one upin '3 there is mounted a` sprocket-wheel 4C, which is driven. by ,the motor, through', thev agency of "5a., ATo tlie.,shat 5 there is also keyed ar speculation bf Letters retener. f

tr`undle-drum 8. Further, there is loos-ely mounted on this shaft 5 the one end of eachof two short frame-'bars 9, while the other ends of these bars are connected by a shaft 10. Between the bars 9 there is mounteda roller 12 loaded with weights 11.' A@n the shaft 10 there is mounted asecond trundledrum 13. Around the two drums 8, 13 there runs an endless apron 14, provided with Scrapers 15. 16 are ropes for elevating the frames 2 and 9, and the dot-and-dash lines in Fig. 1 show the frame 9 in its raised 'posit-ion.' 17 are arms extending rearwardly of the drum 8 for the purpose of sustaining a-sieve. g

When'the sprocket-wheel'4 is driven by the motor, the drum 8 revolves and drags the network 14 lover the ground. The Scrapers thus' dig into the -soil,'rake along the scraped material, and throw it up behind the drum 8. Should there be stones in .the way, the Scrapers will. pass over or around them, as the network admit-s of their yielding in all directions, so thaatthe stones will gradually loosen andbe carried along by the Scrapers. The network during such working .adapts itself to the surface of the ground. If the lattershould be so hard that the momentum of the apron is insuliicient to enable proper operation of the Scrapers, the roller 12 mustbe lowered upon theapron, sol as to load it. It' the soil is to be'scraped to avery considerable `depth, the frame 9 must bedrawn up, whereby the area ofthe scraping-surface is diminished, 4while the ypressure at the place of work is increased.

Referring now to the modifications shown l in Fig. 3, the network 14 is passed around merely a single drum 8, which rotates with the shaft 5. On this shaft, at a suitable disl tance apart, two polygonal disks are-secured, which at their corners are unitedby trundles 19, so thata kind of reel is constituted.- The trundles 19 are held by adjustable brackets 20. Around this reel the network' 14 is applied, and rigidly or resiliently connected with the trundles .19. at suitable places.' 1When thereel 8 rotates, the network'l-t has thetendency to fly out from'the center of'rc tation; 'it thus lhears closely against the ground and scrapes away 'everything that obstructs it.V The material is thrown 11p in .the same manner as in theconstruction with .two drums. In both cases, and also with Qtherarrangements of the scraping-network, individual Vpcmtions of the latter can, if

' and 13). The network may also consist entirely (Fig. 14:) or partly' (Fig. 15) of springs. In the case of sandy soils relativel blunt Scrapers prove adequate. If, however, turf, foliage, stubble, stalks, or the like, havnv `to be out through, such ebstructions mustl first be reduced, that is, the Scrapers must break them through and then cut them, Vloefore they are mixed with the soil. In such cases, Scrapers with cutting-edges, as for example `as those shown in Figs. 5 and 6, should be employed. If the scraping network is to be employedy for various classes of work, the Scrapers must be so secured as to\be readily removable. for instance when the scraper's have also to scrape manure, conveyed by the cart and miX it *with the soil.

In tlf 'present method, the earthA is not f' cut out i cylindrical pieces (as is the case with prior machines, which do not scrape, but rather 'g and pierce), but is removed in a form suited to the resistance offered by the soil, and r eatedly changing.

i The scraped aterial may be thrown upv in the following nner: The remnants of vegetable matter QFig. 1) are overcome by the resistance of the air and rapidly fall to the ground. Fi e, pulverized earth y likewise descends rapndly. Clods and stones e, on the other hand,are hurled to a great distance andfall out on top at the back. In autumn, and in turningover frosty land, this method of'working may be suitable; in warmer countries and fon sowing, it would be suitable, as in such case it is the fine earth that is required on the top. For this purpose sieves 23 (Fig. 3) are stretched between thearms. 17. If these sorting-sieves 23 are` fiat, the scraped material passing through ithem will naturally lie evenly on the land.4

lhe clods and stones being the heaviest -bodies -are vhurled to the highest-part of the sieve, but cannot drop through the meshes and must'therefore return and have a considerable dista-nce to travel. They therefore fall in front of the sieve, at the deepest 'This is requisite,

vplacfffhe pulverized earth y? on the other this manner :naturally only line earth col-4 lects in the furrows, while the ridges are built up of coarse material also. As Fig. 16 shows, different kinds of Scrapers may be disposed at definite parts of the apronr I claim as my invention- 1. A machine for cultivating land, comprising a machine-frame, a roller-frame pivoted to the machine frame, rollers carried ing motion to said rollers, an endless belt or apron passing over said rollers, and Scrapers attached to said endless belt in such a manner direction.

2. A machine for cultivating land, coniprising a machine-frame and roller-frame pivoted to the machine-frame, rollers carried by the said roller-frame, .means for imparting motion to the said rollers, an endless belt or apron passing over said rollers, Scrapers pivotally attached to the said endby the said roller-frame, means for impart-- that they are free to move in any less belt which latter is in the shape of a otally connected to the machine-frame, roll--V ers mounted yin said roller-frame earth engaging means on said rollers, means for actuating the said rollers, and a sinuousshaped sieve located rearward of the said rollers.

In testimony that I claim the foregoing as my invention, I have signed my name in -presence of two subscribing witnesses.
