r This invention relates to a beet-root gathering machine by means of which first'the beetroot tops are cut off, whereupon the beetroots are loosened by shares and then lifted out of the ground by forkshapedlifters so that they aredeposited at the sides of the liftersto be engaged. by an oblique rake, along which'they roll to. the outer'side where they aredeposited in rows, whereas'the beet-root tops also conveyed to the outer side of the machine are deposited in heaps. I s In the accompanying drawings an en1bodi ment of the invention is illustrated by way of example.

Fig. '1, is a top plan view of the machine.

same; 7

Fig. 3 1s a cross section on l1ne 33 of Fig.1.

The machine has a fixed front axle 1 on which the front wheels are mounted, steered by means of axle swivels?) and a steering rod 4 fromthe drivers seat 5 through the intermediary of a steering wheeler the like.

The rear wheel axle is rigid with'the rear wheels so that it participates in theturning movements of the same. On the front axle twolongitudinal members 8 rest and are v rigidly connected to. the same, said members vcarrying in bearings 9 the rear axle 6.

The machine is fitted with three rows of knives and lifters; It is adapted to be at cached toatractor-at the sideof which it runs and with which it is connected'in a suitable manner.

The three knives 10 for cutting off thebeetroot tops are attached to a transverse beam "'11 ending in rollers 12 which are movable V in guides 13 (Fig. 1). 140

' ing ahead of the'knivesf'so that they move over the beet-root tops whereby to the knives the correct cutting. position is given; The

knivescut therefore only so muchfromthe top end of the beet-roots as is necessary to keep together the beet-root top. By adjusting screws 15 the shoes 14 can be adjusted with regard to the knives 10." These knives 10 are the conveying device 31.

connected to guiderods 16 rigidly connected with the transverse beam 11. The rods 16 end in racks 17 with which spur wheels 18 engage, on. the shaft 19 of which a sprocket wheel 20 is keyed, connected by a chain 21 with a thesame in upward direction, or they drop on to the plate 30 and 29 on which latter they are raised onto the conveyor bands 28, so that the tops can easily be conveyed upwards.

The band 28 has transverse bars that push the tops up the plate 29 and throw them onto The lower shaft of band 28 is suspended in bearings fixed on the main frame of the machine, which bearings are not shown, as they areregarded as of minor importance. The plate 29 is suspended from the same bearings, andits lower end forms an extension of both the bearings.

The small trapezoid in Fig. 2 below sleeve 26 and at the right of the head of the-screw 15. forms a sleeve 26 which receives the screw 15. r

The same sleeve receives the vertical shank 10" of knife 10.

The shoe 14 is rigidly connected to the same sleeve '26" so that the plate 14 controls the knife. The sleeve 26 is provided with a slot-26in the front portion of its wall in which the knifebar can yield towards the front when the plate 14 is raised,-the rod 16 having also according slot 16 inorder to enable the abutment to swing out tofwards the rear. when the plate 14 is being raised. v

The plate is hingedly connected at its front end to the rear ends of the plate. 14.

lMoreover-the plate 30 is connected at its rear end with the front and lower end ofthe, plate.

The plate 29 is connected at its rear end to bearings fixed on the frame 8. H

The cut-ofi tops do not drop onto the conveyor band 28-but ontothe plates 30 and 29.

The beet-root tops drop from the plate/ 29 upon a transverse conveying device 31, from Whichithkeydropinto a box 82 arranged onthe side of the machine. Inthis box 32 a rotatable vane drum 33'is arranged, which is normally locked by a spring-controlled latch 34. When this latch 34is pulled back 7 by means of a pull rod 35 through the intermediary of a lever 36 in easy access from the idriver -"sseat'-5, or by the operation of a pedal lover, the vane loaded with beet-root-tops is released, so that the heap of beetroot-tops resting on said vane dropson the ground. I The next following vaneco'mes at the same time to rest on the latch 34 so that the de- "I vpositing of the beet-roottops in the box 32' v is'not interrupted.
