BEET-CLEANER.

Application filed December 18, 1914.

To all w/wmit may concern Be it known that I, ABRAHAM GUDMuND- sun, a citizen of the United States, residing at Payson, in the'county of Utah and State of Utah, have invented a new and useful Beet-Cleaner, of which the following is a specification.

The present inventionappertains to a machinefor cleaning beets or other vegetables or articles, and aims to provide anovel and improved contrivance for separating beets or other articles from'rocks, sand, pieces of wood, or other trash and refuse.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in its preferred embodiment in the accompanying drawings, wherein z- Figure 1 is a plan view of theimproved apparatus. Fig. 2 is a side elevation thereof. Fig. 3 is a longitudinal section of the machine, Fig. 1 is an enlarged fragmental section of the drum.

In carrying out this invention, there is provided a supporting frame including a pair of standards or uprights 1 at one end, and a pair of standards or uprights 2 at the other end, the standards 1 and 2 at the opposite sides being connected by longitudinal beams 3 which are inclined at a slight angle from the standards 1.

Disposed between the standards 2 at the upper ends of the beams 3, is a roller or pulley wheel 4, the shaft 5 of which is journaled through the standards 2. A similar roller or pulley wheel 6 is disposed between the standards 1 at the lower ends of the beams 3, and its shaft 7 is journaled through bearings 8 slidable within vertical slots 0r guides 9 provided in the standards 1. The bearings 8 are yieldably supported by means of coiled wire expansion springs 10, whereby the lower roller or pulley wheel 6 may yield downwardly when necessary. An endless conveyor belt ll is trained around the rollers 4: and 6, and its upper run is disposed between the beams 3, to form with Specification of Letters Patent.

the beams, a trough for receiving the beets or other vegetables or -articles to be separated.

Transverse shafts 12 are terminally journaled through the beams 8 below the upper run of the conveyor belt 11, and are rovided with eccentrics 13 between the beams 8 and upon which the upper run of'the con veyer belt rests. The shafts 12 of theeccentrics 13 are opei'atively connected byany suitable means 14, to the shaft 5 of the roller 4, whereby when the conveyer belt is uperated,the eccentrics 18 in rotating will vi brat-e the upper run of the belt, to separate or scatter the beets, in order that they will not remain piled upon each other when passing to the lower portion'o'f the conveyor belt, it being understood that the conveye'r belt is so actuated "that its upper run moves downwardly or toward the standards -1 "to carry the beets therewith.

A drum 15 is mounted between the standards 1 above the lower roller 6 of the conveyer belt, and includes a pair of hubs 16 secured upon a shaft 17 which is journaled through the standards 1. The drum 15 also includes a relatively wide rim 18, and opposite sets or series of spokes or rods 19 terminally secured to the respective hubs 16 and the edge portions of the rim 18. The spokes 19 are arranged in pairs at the opposite sides of the drum, to provide slotted radial guides. The lower portion of the drum 15 is just spaced sufliciently above the lower. rollers 6 of the conveyer belt, to enable the beets and trash to pass conveniently between the drum 15 and roller 6.

An annular series of radial rectangular open frames 20 are disposed within the rim 18 of the drum 15, between the opposite spokes or guides 19, and the side bars of the frames 20 are provided with inner and outer lugs 21 engaging the guide slots formed by therespective pairs of spokes 19, and whereby the frames '20 are guided for radial movement. A plurality or series of plungers 22 are slidable through theouter and inner cross bars of each frame 20, and the outer ends of the plungers 22 are 'arranged to project outwardly through suitable apertures 23 provided in the rim of "the drum, the outer ends of the plungers 22 having reduced tips 24. (lollars'25 are fsecured upon the 'plunger's '22 adjacent the outer cross bars 'of't'he frames 20, and are Patented Sept. 11, 1915.

'seatable against the outer cross bars of the carrying the plungers 22 having the beetengaging tips or pins 24, a pair of cam rings 27 are disposed between the sides of the drum 15 and the standards 1, and are secured in any suitable manner to the standards. The rings 27 are each provided with an endless approximately annular cam slot 28, and the concentric sections of each ring 27 are connected byv outwardly projecting yokes 29 which permitthe outer lugs 21 of the frames to pass readily around the cam slots 28 through which the said outer lugs 21 extend. Those portions of the cam slots 28, directly above the conveyer belt 11 and between the upper and lower portions of the rings 27, are concentric with the shaft 17 of the drum, as at .31, and those portions designated 33 of the slots 28 between the portions 32 and the top of the rings 27, are curved inwardly slightly. This inward curvature of the portions 33is to be taken with respect to the curvature of the portions 31 about the shaft 17 as a center.

The shaft 17 of the drum 15 is rotated by i a prime mover or driving means of any sort,

whereby the drum 15 is rotated vcounterclockwise, as seen in Figs. 2 and 3. The shaft 17 of the drum and shaft 5 of the roller 4 are operatively connected by means of a belt or any other suitable means 34, whereby the conveyor belt will be actuated when the drum 15 is rotated.

A'chute 35 is attached to the standards land extends downwardly from the lower V roller 6 of the conveyer belt, and a chute 36 extends from the upper end of the chute 35 fromla point below the outer portion of the drum 15. a I r JIn operation, supposing the drum 15 to be rotated properly, whichwill also drive the'conveyer belt, the sugar beets are discharged or dumped onto the upper run of the conveyer'vbelt between the beams 3. The upper run ofthe conveyer belt in moving toward and under the drum 15'will carry the beets and trash therewith, and the eccentries '13 in rotating will kick or ar the beets so that they will scatter throughout the area of the conveyor belt to prevent the beets passing under thedrum 15 while piled one upon the other. In this manner, a single layer of the beets is carried under the drum 15. Now, as'the drum15 is rotated to carry the frames 20 therewith, the outer lugs 21 of the frames 20 in passing through the portions 31 of the cam slots 28 will cause the frames 20 to be moved outwardly sufficiently to project the tips or pins 2% and shoulders of the plungers 22 through the apertures 23 of the drum rim 18, and as the tips or pins 2e move downwardly toward the conveyer belt, they will enter the beets and will cause the beets to cling to them. \Vhen the frames 20 move adjacent the conveyer belt, the plungers 18 are projected, as seen in Fig. 4, so that the tips or pins 2% and shoulders of the plungers are projected beyond the rim 18 of the drum, and thus when the beets are engaged by the tips or pins 24 of the plungers they will seat against the shoulders of the plungers to force the plungers inwardly or outwardly against the tensions of the springs 26. Then, when the frames 20 pass along the portions 32 of the cam slots 28, the beetsbeing carried away from the conveyer belt, will enable the plungers 22 to spring outward to space the beets from the rim 18 of the drum, and to thereby enable any sand or foreign matter between the beets and rim 18 to drop downwardly through the refuse chute 35. Finally, as the frames 20 move along the portions 33 of the cam slots 28, the frames 20 will be moved inwardly to retract'the pins 24 within the rim 18 of the drum, and to thereby release the beets and enable them to drop into the chute or receptacle 36. In this manner, the pins 24 engage and carry with them, the beets, but let the rocks, wood and other trash or refuse remain on the conveyor belt so that they will be discharged down through the refusechute 35 when they pass over the lower roller 36 of the convcyer belt.

The lower roller 6 being yieldably supported, may move downwardly when the beets or trash render it necessary. to prevent clogging or the crushing of the beets. The pins 24 being of less diameter than the plungers 22, provide shoulders at the butt ends of the pins 24, against which the beets rest when the beets are engaged by the pins. The plungers 22 being yieldably projected. under the influence of the springs 26, may yield inwardly when they encounter rocks or other unyielding objects upon the conveyer belt. a

It is thus possible, with the present contrivance, to continually pour the sugar beets onto the conveyer belt, in order that the beets may be separated from the refuse and trash by a continuous operation. The present device is adapted particularly for separating or cleaning sugar beets, although it may be employed with success for cleaning or separating other articles as well. The present apparatus thus enables the beets to be delivered into the cutting machine, without the liability of refuse or foreign matter.

being delivered into the cutting machine with the beets, which wo-uld-be liable to'dull or clog the cutters.

If desired, rollers may-be mounted upon the outer lugs 2-1 of the frames 20, to work within the cam slots, for reducing the friction.
