BEET-HARVESVTER.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed April 1, 1905. Serial No. 253,236.

To all whom it may concern.-

Be it known that 1, Louis S'riMAR'r, a citizen of the United States, residing at Humboldt, in the county of Brown and State of VVisconsin, have invented a new and useful Beet-Harvester, of which the following is a specification.

This invention relates to beet-harvesters, and it has for its object to simplify and im prove the construction and operation of this class of devices.

WVith these and other ends in View, which will readily appear as the nature of the invention is better understood, the same consists in the improved constructionand novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of embodiment of the invention, it being understood, however, that no limitation is necessarily made to the precise structural details therein exhibited, but that various changes and modifications may be resorted to within the scope of the invention.

The single view illustrates in perspective a beet-harvester constructed in accordance with the principles of the invention.

A beam 1 of ordinary construction is provided at its rear end with guiding-handles 2 2 and at its front end with a slot 3 for the passage of a standard 4, bifurcated at its lower end and provided with spindles for a pair of supporting-wheels 5. The standard 4: is provided with a plurality of perforations 6, whereby it is vertically adjustable upon a supporting pin or bolt 7 which also serves for the attachment of the draft-clevis 8.

Pivotally connected with the beam is a U- shaped yoke 9, the arms of which are provided with registering perforations 10 for the passage of the bolt or pivotal pin 11, which supports the yoke 9. The upper end of the latter is provided with a cross-bar 12, connected by a spring 13 with a fixed point of attachment, such as an eyebolt 14, connected with the beam, the tension of the spring 18 serving to move the upper end of the yoke in a rearward direction.

15 is a V-shaped frame pointing rearwardl y and having the ends of its side members curved upwardly and inwardly to form supporting-brackets 16 and terminating in inturned lugs 17 engaging perforations 10 in the side members of the yoke 9, with which the V-shaped frame may be connected by springing the lugs into place to form a hinge connection, as will be readily understood. Said frame is furthermore secured and the extent of its movement is limited by means of suitably-connected clip-bars 19, engaging the front and rear sides of the side members of the yoke. Therearwardly-convergingsidemembers of the V-shaped frame are provided upon their inner or forward sides with triangular cutters 20, which may be formed integral there- I with, although said cutters may, if preferred, be made separate and connected with the frame in any convenient manner. The side members 16 of the frame 15 are provided with brackets 21, pivotally supporting a roller 22, which is sustained a short distance above the V-shaped cutter-frame.

To the sides of the beam, near the rear end of the latter, are bolted or otherwise suitably secured two colter members 23, which below the'beam are offset or outwardly expanded, as clearly indicated at 24c. The front edges of these colter members, especially at the lower ends of the latter, are to be sufliciently sharp to penetrate readily into the soil and to cut through the latter adjacent to the row of beets which is to be operated upon. These colter members are to be connected with the beam by means of suitable braces 25 26, whereby they will be enabled to resist any strain to which in practice they will be liable to be subjected. Suitably secured to the lower ends of the colter members are the beet-lifters 27, which consist of suitably-constructed subsoiling-blades having beveled front ends 28, terminating in cutting edges 29, whereby they will be enabled to penetrate readily into the soil to the desired depth. The sides of these lifting members are likewise inclined or beveled in order that they may be enabled to cut as close to the beets as possible without danger of injuring them. Suitably connected with the lifters in rear of the colters are rearwardly-extending guides 30, upon which the beets after being loosened and pushed upwardly by the lifters will be elevated, carried rearwardly in a manner which will permit dirttobecomedetache'd therefrom,anddumped in rear of the machine to be subsequently I gathered.

The operation and advantages of this-inven- IIO be crushed by the roller 22 and will be detached about level with the ground by the cutters connected with the V-shaped frame 15. The subsoiling-lifters will loosen the beets and push or lift the same in an upward direction until they become engaged by the guides or carriers 30, whereby they are permitted to pass rearwardly to be presently dumped upon the ground.

The construction of this machine, as will be seen, is extremely simple and inexpensive. The various parts may be readily adjusted so as to cause the crushing mechanism, the topping-knives, and the lifters to operate at the proper depth with relation to one another. Means may be provided whereby the position of the top-crushing roller may be adjusted with relation to the topping-frame; but such means have not been illustrated in the drawing. If any obstruction should be encountered by the topping-frame, the spring 13 will permit said frame to yield in a rearward direction and to swing clear of such obstruction, over which it will be carried, either by the roller 22 or by the runners formed by the curved arms 16, as the case may be.

Having thus described the invention, what is claimed is 1. In a beet-harvester, a beam, a rocking member connected with said beam, and a topper hingedly supported by said rocking member.

2. Abeam, a spring-actuated rocking member connected with said beam, and a topper hingedly supported by said rocking member.

3. A beam, a rocking yoke connected therewith, and a topper connected hingedly and adjustably with said yoke.

4. A beam, a rocking member connected therewith, and a topper having resilient arms pivotally engaging said rocking member.

5. A beam, a rocking yoke pivotally connected therewith, and a topper having resilient arms pivotally connected with the arms of the yoke.

6. A beam, a rocking yoke connected therewith, a topper having resilient arms pivotally and adjustably engaging the arms of the yoke, means for limiting the movement of the topper with relation to the yoke, and spring means acting upon the yoke to move the topper in a forward direction.

7. A beam, a yoke connected pivotally with said beam, a topper connected with said yoke, and spring means acting upon the yoke and normally forcing the topper in a forward direction.

' 8. A beam, a rocking yoke pivotally connected therewith, a topper and a crushingroller adjustably connected with said yoke near its lower end, and spring means connected with the upper end of the yoke for normally forcing its lower end in a forward direction.

9. In a beet-harvester, a pivotally-supported topper-frame having resilient arms provided with bearings. and a crushing-roller supported in said bearings.

10. A beam, a spring-actuated rocking member connected therewith, a topper connected pivotally with said rocking member, and a top-crushing roller supported by the topper.

11. Abeam,aspringactuated rocking member connected therewith, a topper-frame having resilient arms pi votall y engaging the rocking member and provided with bearings, and a top-crushing roller journaled in said bear ings.

12. A beam, a yoke pivotally connected therewith and provided with perforations, and a topper-frame having arms terminating in lugs engaging said perforations.

13. A beam, a yoke pivotally connected therewith and provided with perforations, a topper-frame having arms terminally engaging said perforations, and clip members engaging the yoke and limiting the movement of the topper-arms.

14. A V-shaped topper-frame having arms provided with brackets, and a top-crushing roller supported by said brackets.

15. A triangular toothed topper-frame the side members of which terminate in upwardly and inwardly curved members, pivotal supporting means for the latter, and means for limiting the movement of the topper-frame.

16. A tiltable topper-frame having cuttingarms curved to constitute runners when the frame is tilted.

17. A pivotally supported topper frame having curved resilient arms converging rearwardly and equipped withv cutting means.

18. A pivotally supported topper frame having curved arms, and a top-crushing roller supported by said arms.

.19. A beam,aspring-aetuated rocking member connected with the beam, a tooth-carrying topper-frame connected pivotally with said rocking member, and means for limiting the movement of said topper-frame.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
