Specification of Letters Patent.

llatcnteil Oct. 226, 1920.

Application filed October 28, 1916, Serial No. 128,253. Renewed March 19, 1920. Serial No. 367,208.

To all whom it may concern Be it known that I, Louis 0. GRAHAM, a citizen of the United States, residing at Knox City, in the county of Knox and State of Missouri, have invented new and useful Improvements in Beet-l larvesters, of which the following is a specification.

This invention relates to beet harvesters and it has for its object to produce a machine of this class which will possess superior advantages in point of simplicity, durability and general efficiency.

A further object of the invention is to produce a beet lifting or extracting mechanism of simple and improved construction involving the use of a plurality of lifting elements or hooks carried by an endless chain, said elements being of a nature to positively engage and lift the beet roots from the ground.

With these and other ends in view which will readily appear as the nature of the in; vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

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

In the drawings,-

Figure 1 is a side elevation of a machine constructed in accordance with the invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a longitudinal sectional view taken on the line 38 in Fig. 2.

Fig. i is a rear elevation.

Fig. 5 is a perspective detail view of some of the beet lifting elements or units showing also a portion of the chain on which said elements are mounted.

Fig. 6 is a detail view of a portion of the frame showing one of the wheel carrying spindles.

Correspondingparts in the several figures are denoted by like characters of reference.

The frame 15 of the improved machine is supported on a revoluble axle 16, the

transporting wheels 17 being fixed on said axle so that the latter will revolve in its bearings to enable power to be transmitted therefrom for the purpose of driving the moving parts of the device, as hereinafter set forth. The rearward part of the frame is supported on gage wheels 18, the spindles of which, 19, are carried by brackets 20, said brackets being vertically adjustable on the rearward portion of the frame, which latter may thus be tilted so as to raise or depress the forward portion of the frame and the operating elements carried thereby.

The frame at its forward end is provided with forwardly extending convergent arms 21, the front ends of which are secured on the sides of the tongue 22 by means of a bolt 23 that extends transversely through the tongue, the rearward end of the tongue being secured on a cross bar 2% of the frame.

45 is a shaft supported for rotation in the upper portion of the main frame adjacent to the rearward end thereof, said shaft receiving motion through the medium of in termeshing spur wheels 4:6, 47 from a driven shaft 4L8, the intermeshing spur wheels be-.

ing so proportioned as to properly speed the shaft 15. The latter" carries a sprocket wheel 49 over which is trained a chain 50 which will be known as the lifter chain, and the lower portion of which may be guided over an idler 51 on a shaft 52. The lifter chain 50 is composed of U-shaped links each comprising side members 53 which are connected together by a cross bar 55, each side member being provided at the ends thereof with eyes .54: engaging the cross bar or bridge portion of a proximate link. Hingedly supported on the cross bar 55 of each link is a beet lifting element B consisting of an approximately L-shaped hook which is made preferably of sheet metal, such as steel or other material, of suitable strength and resiliency for the purpose for which it is intended. One arm 56 of each hook or element 13 is provided with an eye or eyes 57 hingedly engaging the cross bar 55 of one of the links. Another 58 which extends approximately at a right angle to the arm 56 is provided with a l-shaped notch or recess 59 adapted to engage a beet root which will become wedged between the side walls of said notch by the advancing movement of the machine when in operation. 60 is a beet receiving hopper. Bolted upon or otherwise connected with the wall portion for the purpose of transmitting motion from the main axle of the machine to the various driven shafts, and while such transmission means may be arranged substantially as shown in, the drawings no detailed description of the same is necessary.

In the operation of this device it will be seen that as the machine is drawn over the ground the beet lifting hooks or elements mounted on the lifter chain 50 will engage the beet roots which will become wedged in the V-shaped notches 59, it being understood that the lifting hooks or elements will be disposed closely together so that it will be practically impossible to miss a beet. The roots will be lifted or extracted from the ground partly by the progressive motion of the machin e, but mainly by the lifting action of the chain 50, and the roots as they are elevated will becomedetached by the action of the arms 61 and deposited in the hopper 60. The contents of the hopper 60 may be discharged at any time, formin a pile on the ground which will be convenient of subsequent gathering. 7

Having thus described the invention,what is claimed as new, is

1. In a beet harvester, a beet extracting device comprising a 'driven endless chain having flexibly connected U Shaped links, and beet pulling units hingedly connected with the bridge pieces of the links.

2. In a beet harvester, a beet extracting device comprising an endless driven chain,

unit consisting of an L-shaped member having one arm provided with terminal eyes engaging the bridge piece of a chain link, and another arm extending substantially at a right angle to the first'mentioned arm and having a V-shaped beet engaging notch.

In a beet harvester, a beet extracting device comprising an endless driven chain having flexibly connected U-shaped links,

and beet lifting units'carried thereby, each unit consisting of an L-shaped member having one arm provided with terminal eyes engaging-the bridge piece of a chain link, and another arm extending substantially at a right angle to the first mentioned arm and having a V-shaped beet engaging notch, in combination with a supported member, stationary with respect to the chain and adapted to disengage the beets from the notched arms of the lifting units.

5. In. abeet harvester, a beet extracting device comprising'an endless driven chain having flexibly connected U-shaped links, and beet lifting units carried thereby, each unit consisting of an L-shaped member having one arm provided with terminal eyes engaging the bridge piece of a chain link, and another arm extendingsubstantially at a riglitangle toothe first mentioned arm and having a V-shaped beet engaging notch, in

combination with a supported member, sta- 'tionary with respect to the chain andadapt- LOUIS ORVILLE GRAHAM,
