4 Claims.

My invention relates to beet handling devices and has for its lobject to provide a new and eicient method of lifting beets from any suitable plow and carrying them through a series of belts to place them at the topping knives at a proper level so that each beet will be topped evenly with no waste and with no crown left thereon.

A further object is to provide means for handling beets which will be highly efcient, and which will raise the be-et so that when it is topped it will be correctly topped, thereby, eliminating much expense to the present method of handling beets and eliminating the costly labor of topping the beets after they have been plowed.

A still further object is to provide a device for handling beets vby the tops or leaves so that when the beet has been raised and is ready to be topped,

the tops or leaves of the beet will be so held that A the crown of the beet will be in the proper position for the cutting knives.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims. g

In the drawings I have shown my machine as a frame work-A, suspended on an axle I with wheels B to support the axle, and extending front from the axle I provide a frame work C with the front end thereof curved upward to a front support bracket 2, with wheels 3 supporting the bracket 2 on an axle 4.

The front end of the frame work A is suspended between the frame work C and is connected adjustably thereto by a link bar 5 and level adjusting or raising and lowering lever 6, with a knotched rack and dog to control and'hold the` frame work at the desired level. Y

At the front end of the frame work A I provide two depending bracket frames 8 and 9 on each side ofk the frame work A extending'inwardly to near the center of the machine, one frame on each side. The ends of these two frames are bifurcated alike and as each frame is identical, I will describe but one. The inner faces of each leg of the bracket frames 8 and 9 are made of channels Ill to carry laterally movable U-shaped brackets II and I2 therein. The brackets II and I2 are provided with balls I3 on which the brackets ride within the channels I0, some of the balls being on the underside of the brackets and some of them being along the sides, so that the brackets move laterally in the channels of the frames 8 and 9 and each bracket is provided with a retention spring I4 carried on a rod Ida to normally hold the brackets toward each other at the center of the machine. Through the brackets Ithen mount the vertical shafts E5 and I6 on which the two'sheave wheels Il and I8 are mounted and carried with the ends of the shafts rotating in the sockets in the brackets in which they are mounted. Thus, the two sheave wheels Il and I8 are mounted for rotation and at the same time mounted for lateral or side movement integral with the side movement of the brackets. These two wheels carry belts E and F therearound preferably of asquare type as shown in the drawings. These two belts extend back parallel to the ground and front end of the frame work A and spaced apart guide rollers I9 and 20 and rider wheels 2| and 22 are provided to turn the belt up at an incline G as shown in Figures 1 and 10. There the belts are passed over the top of other spaced apart rider wheels 23 and 24, 55

cutting knives; at the proper level so that no waste 76...' bfrlsts 8.1.-. are ihren from Meer and guide rollers 25 and 26 and again parallel to encircle two sheave wheels 21 and 28. Onto the frame work A I then mount flanged plates 3|) and 3|, one on each side of the incline and bent at the top end to be parallel to the belts. Through these flanges on plates 3|) and 3| I pass shafts 40 with the inner ends of the shafts carrying pressure guide flanged rollers 4|, said rollers to ride with and hold the belts continuously in frictional contact, and springs 42 are carried on each shaft 4Q betweenV the flanges on the plates 39 and 3| to normally hold these two belts together during the upward travel on the friction` engaging portion of their travels during their use as beet top lifters. Thus, by this construction the engaging portions of the two belts E and F are held together in frictional contact with each other at all times by the ligrfgsstire alger-texil by the springs. Also the two front sheave wheels |1 and I8 being mounted with spring pressure behind them @is in holding, the belts together during their upward travel.

The two back sheave wheels7 2l and 2 ,8 are also spring held as will be later described to normally hold them in frictional contact.

The beets are dug from the ground o r loosened therefrom by any suitable plow as indicated by dotted lines a in Figure 1 and are in such a raised position that when the two., front sheaves pass thereover, they engage some of the leaves and as the belt engages the. leaves it raises the beet through the spacev behind the belt and to its highest point of elevation with the beet suspended down from the tops. As the position of the beet in relation tothe tops will vary and as the. belt may grasp. the top at different distances from the beet theyV are then leveled offto a uniform position at the. rear. of the machine by passing through a series of; endless belts` and gripped by lingers to finallyY make each` beet pass into the willy take` place.

Thesebelts areshown as endless belts and commence with sheave wheels 516 and 5| being mounted on or formed on the shafts 52A and 53K: of the sheave wheels 2.1v and 28, just below the level of thewheels 21 and 28:.;and another-pair of coacting and corunning wheels 5 4 and55is mounted rearwardly of the machine on shaftsl 56 and 5] on a plane level with. the wheels 5.0 and 5 The belts 58I and 59. arie then carried on the vslzlgieelsr5|lV and 55, and 5|. and 575A. respectively.

Qn the shafts 56 and 5,1 under the. wheels 54 and 5,5` I then provide another pair of like Wheels 66 and 6|i and back of this pair of wheels on the same leyel there is` another like pair of sheave wheels', 62, and. 6 3 with endless belts 64 and 65 running around the wheels 60. and 62p, and 6|.

and 63 respectively. These wheels 621. and 63-y aeortshafts 66 and 61 andy on these shafts under the wheels 6 2,v and'Y 63( there is another pair of like sheave wheels; 68 and69. Another pair of Wheels 18`aind1| are mounted: on the same levell as the wheelsl-and 69` on shafts 12 and 13 and endless belts 1A and. 15 encircle these two pairs of Wheels. In like manner` two more sets of wheels and belts are,4 provided tov lower the beets to the cutting knivesof the machine. The lastset of endlessk b=;1t, ;.'|s.` and 11. carni-.ciV on the wheels 1.a and so, and. 19 andA 8| are those belts/Which en d. the carrying, o f the, beet and bring: it intocontact with thex `cui'tingl knives. The cutting knives 8 2:` and 83; are mounted onE vertical shafts 84 and 85V, driven. by sheave wheels 86 aus supported by cross drive shaft S mounted transversely of the frame work A and near the rear end of the machine with a drive chain SI driving the shaft from the main axle sprocket 88 on the axle and with a sprocket 89 on the shaft S to transmit the power thereto. The power is transmitted from the shaft S to vertical shafts 9|) and 9| through bevel gears in the housing 92 and the power from the Vertical shafts is transmitted to the shafts 84 and 8,5, by sheave wheels, and belts4 92a transmit the power to the sheave wheels 86.

The power for moving the train of endless belts and the main belt is transmitted from the vertical shafts and 9| by sprocket wheels 93 and 94 carrying Chains 95 and 96 to the sprocket wheels Ql arid 33, on the top ends of the shafts 66 and 61 and this power is then transmitted through the chain of; endless belts.

Each s et of double sheave wheels and the front set of sheave wheels 21 and 28, and 56 and 5| is carried in li-shaped brackets T, shaped similar to the. brackets and |.2 at the front end of the machine, the only difference being that the center portion of the brackets is longer and the` legs are shorter. These brackets are each alike except that the center `portion of each set of two is longer as. the rearv end of the machine is reached to place the belts in the step like lowering positions. Two of these brackets are shown in Figures 8 and 9.` These brackets T have suitable bearings or balls |03 on which they can run and each` bracket is provided with a horizontally extended shaft |64 extending outwardly therefrom and these shaftsv are supported in. bearings |05 with springs |116 carried between the bearings to normally hold the brackets toward the center of the machine and. therefore hold the belts in frictional Contact at all times.

The bearings. are mounted on vertical spaced apart support boards V, securedA in place by longitudinal struts- Qr anglev irons, and the other supports. necessary tov properly brace the frame work A and the. component parts of theV machine. The brackets through which, the shafts 6 6 and 6,1 are vertically extendedfor the drivey sprockets 91 and 9.8, have the shafts passed up therethrough with the longitudinal'strutsrslotted at |01 to allow the side motion of the shaftscaused by the top of the beets. passing along-their path of travel between the endless belts.4 The brack-f ets 'II are Carried in tracks, |311I extendingv wardly toward the center of the. machine. and each bracket is, supported fromQthe top and bottom ends alike. The tracks are; mounted in thev frame workA by suitable supports.

In order to bring` theT beets'allV to, al common level at the introduction tothe topping knives I then provide a. belt ||0 on each side of the. machine which-` ,belt is carried. back along the machine from a front sheave wheel |||,}'tora rear sheave wheel. H2, thence front horizontal with. the ground parallet to, the bottomI of the frame over an idler sheave wheel ||3 and back upto` the, wheel This makes two` triangular endless, belts on` each side, of the machineand each belt is then provided with Li-shaped brackets ||,4 onv the outer. side. thereof each bracket being` formed with` 'li-shaped openings through the legs thereof through which aligning knife edge. fingersorrods.` lare carried: and; operated. These fingers are made with ther top, beet engaging endi T-,shaped, with theI top, cross barof the T. rounded on the topsurfaceand. with the, bottom leg of the 1I Shaped tocutdown through the leaves.- ,coinbiorf draw each, beetdown; to

the level of the next engaging section of endless f belts or to the level of the knives. When the base portion ||8 of the fingers engages solid beet it cannot cut down any farther and therefore holds the beet at that level and as the top section of the endless belt is slanting down toward the rear of the machine, this naturally draws the beet tops down through the belts should the beet be too high or, will hold the tops rigid until the next step in the endless conveyor belts engages the beet top taking a grip thereon at a lower level.

The rear end of each of these fingers is provided with a ball ||9 and with a rotatable ring |29 with the ball and ring to run within and operate in a guide rail |2|, there being twolike guide rails on each side of the machine. These guidel rails are bent to bring the fingers into contact with beet tops after they have been engaged between the two belts 58 and 59 at the front end of the machine and to be disengaged from the tops at the rear of the machine just before they engage cutting knives. The rails are supported on boards |22 which are a part of the frame work A and as additional support for the belt I provide support guide rollers |23 carried under the belt along the top from the front sheave to the rear sheave wheel to properly support the belt and hold it in alignment. These rollers are carried on shafts |24 which are also mounted onto the boards |22. Aligning bars |25 and |23 are secured to the frame work to engage the top side of the knife edge rods H5 and hold them to a line sloping downwardly toward the rear of the machine parallel to the belt and to prevent vibration of the rods H5.

As an additional tension means for the endless belts which are used to convey the beets back to the rear of the machine, I provide guide and tension rollers |21 supported by pairs of bracket rods |28 which in turn are supported on the same boards to which the support members for the sheave wheel brackets are supported. These bracket rods |28 extend back through vertical plates |29 with springs |30 carried on each bracket to normally hold the rollers |21 engaging the back side of the engaging face of all of the friction engaging endless belts in the step down flight.

The operation of the device is as follows:

The beets are picked up at the front by engaging the endless belts E and F with the tops and at the same time the beets are loosened in the ground. The endless belts E and F then elevate the beets to the top horizontal stretch of the belts where the tops are then engaged by the belts 59 and 58 and from this point back the beets are carried in the endless conveyor belts from one downward step to the next until the beets engage the topping knives. As an aid to the belts the fingers engage the tops and the crown of the beets and either hold them in the position in which they are being carried or lower them down, depending upon just where on the tops the belts are engaging. The belts and fingers then lower the crown or adjust the crown of the beet to meet the topping knives 82 and 83 at the proper place at the crown of the beet. This operation is continued as the machine is drawn fo-rward along a row of beets.

Having thus described my invention, I desire to secure by Letters Patent and claim:

l. In a beet topper, the combination of a suitable framework suspended on wheels; means to adjustably support the front end of the frame work; a pair of co-acting frictionally engaging endless belts mounted with the front end parallel to the ground and with the rear end raised and parallel to the ground with the belts to run from front torear where they are frictionally engaged in the middle of the framework; pairs of steplike descending series of belts mounted for friction Contact between pairs rotating in like manner to the first mentioned belts, the step-like pairs of belts to lower or raise the beet to a common level at the rear of the machine; and rotating disk knives for cutting off the tops of the beet when they have been brought tothe common level desired.
