HAND BEET TOPPER Filed July 5, 1933 Patented Aug. 28, 1934 PATENT; OFFICE a 1 UNITED STATES This invention relates to a hand operated sugar beet topping device. The usual sugar beet harvesting operation consists of first lifting or plowing the beets from the ground so that they lie in 5 rows thereon. The topper then moves along the row lifting each individual beet and cutting the top therefrom with his topping knife. The topped beets are left lying on the ground until loaded into the wagons for delivery to the factories. The topped beets arethus exposed to the air and sun for relatively long periodsof time which greatly reduces their moisture content and weight. This reduction correspondingly reduces the beet growers income since he is paid according to the weight of the beets when delivered.

The principal object of this invention is to provide a hand operated topping device which can be conveniently and rapidly employed to top the beets while they remain in the ground so that the beets need not be dug until the grower is ready .to deliver them. This eliminates the usual exposure of the topped beets to the air and sun and the corresponding reduction in weight.

Another object of the invention is to provide a hand operating beet topping device which will make it unnecessary for the operator to pick up the beets, thereby eliminating a motion on the part of. the operator and increasing his capacity.

A further object is to so construct the device that it will automatically determinethe amount of top that is to be cut from each beet.

A still further object is to provide means for ejecting the beet top from the device after it has I been removed from the beet.

Other objects and advantages reside in the detail construction of the invention, whichis designed for simplicity, economy, and efiiciency. These will becomemore apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying 1 drawing which forms a part hereof. Like numerals refer to like parts in all views of the draw- 1 ing and throughout the description.

In the drawing: Fig. 1 is a perspective view illustrating the invention as it would appear in use.

Fig. 2 is a front elevation of the improved topper illustrating it in the open position.

Fig. 3 is a similar view illustrating the topper in the closed position. A

Fig. 4 is a detail section taken on the line 4-4, Fig. 2.

Fig. 5 is a side elevation of the improved topper showing the handles in the closed position.

The invention comprises: a pair of knife arms 10 and 11 which are hinged at their upper extremities between two yoke plates 12. The lower extremities of the knife arms 10 and 11 carry knife blades 16 and 17 respectively. The yoket plates 12 are placed on each side of a vertical guide member 13. A guide pin 14 passes through the yoke plates and through a vertical slot 15 in the guide member 13 so as to allow the plates 12 to move vertically thereon.

A bent, handle member 18 is pivoted on each face of the guide member 13 by means of a common pivot pin 19. Thelower extremity of one of the handle members 18 is hinged as shown at'20 to the blade arm 10. The other handle member e is hinged as shown at 21 to the blade arm 11. The upper extremities of the handle members 18 terminate in handles 22, preferably secured to the handle members 18 by means of ferrules 23.

It can be readily seen that, as the handles 22 are 7 swung apart, they will cause the handle members 18 to swing the blade arms 10 and 11 apart. As the blade arms 10 and llswing outwardly they will, owing to their fixed pivot 19, raise the yoke members 12 on the guide member 13. The slotted 2. hole 15 allows for this upward movement. Since they move outwardly simultaneously and equally, however, they will lift the yoke members verti- 'cally so that the pin 14 will always be maintained over the pin 19 and the guide member will remain vertical at all times.

The lower portion of the guide member 13 is preferably formed into a spindle 24 which terminates in a pointed extremity 25 at its bottom. A set collar 26 may be set at any desired position on the spindle 24 by means of a suitable set screw 2'7. A's lidable sleeve 28' is supported on the lower extremity of the spindle by means of a vertical spring 29. The bottom of the sleeve 28 is provided with a gage flange 30. g

The inner edges of the blades 16 and 17 are sharpened, preferably on their upper sides only so that their lower surfaces will be continuousto the extreme edges. The sharpened edges are notched, as indicated at 31 to fit about the pointed extremity 25.

In use, the operator grasps one of the handles 22 in each hand, suitable hand grips 32 may be provided to facilitate the gripping operation. He then opens the handles and drops the point 25 of the spindle into the top of a beet. This causes the gage flange 30 to strike the beet and forces the sleeve 28 upwardly on the spindle 24 until it strikes the set collar 26. 1 This limits the amount said spindle and'adjustable to any 'fixed'position "by means of aset screw therein.

of insertion of the point and determines the place where the knives will enter the beet.

The handles are then closed to bring the knives together and sever the top from the beet. The topper is then lifted and opened. The spring 29 then expands and throws the severed top from the spindle 24 and the device is then ready for the next beet. If it is found that the top is being cut totoo greata depth, the set screw 27 may be loosened'and the collar 26 lowered the desired distance, or vice versa.

The topped beets can be left in the ground until desired for delivery so that they will not onlyibe protected from loss of moisture but .willgather additional moisture so that they will not lose weight while awaiting delivery.

It will be noted that the operator always tains an upright position and'is never-required to stoop to pick up a beet or its top. This, greatly relieves the strain upon the operator and the labor involved, ibesides: speeding up :theuwork and increasing-the output encapacity-of the operator.

' The-spindle 24'not only serves to gagethe depth of :the .cut'but'also servesto center and hold the device firmlyin-position during the topping oper- .ation.
