Specification of Letters Patent.

Application filed February 14, 1911.

Serial No. 608,517.

To all whom it may concern:

Be it known that I, HENRY E. BERcoT, a citizen of the United States, residing at Everett, in the county of Snohomish and State of Vashington, have invented a new and useful Beet-Blocker, of which the following is a specification.

This invention has relation to beet blockers and consists in the novel construction and arrangement of its parts as hereinafter shown and described. I

The object of the invention is to provide a simple and an effective machine to operate upon two rows of beets at the same time for the purpose of removing excessive plants from the row. The machine is of such structure that the chopping knives may be adjusted toward or away from each other in order that they may properly operate upon the plants irrespective of the space between the rows also the machine is provided with means whereby the knives may be raised or lowered so that they may operate upon the plants at the surface of the soil or a desired distance below the surface.

In the accompanying drawingsFigure 1 is a top plan view of the beet blocker. Fig. 2 is a side elevation of the same. Fig. 3 is a detailed side elevation of a portion of the same showing adjacent parts in section.

Fig. 4 is a transverse sectional view of an axle forming a part of the blocker. Fig. 5 is a front elevation of the knives used upon the blocker.

The beet blocker includes a frame 1 which is provided at its sides with brackets 2. An axle 3 is j ournaled in the said brackets and traction wheels 4 are mounted upon the end portions of the said axle 3. The hubs of the traction wheels 4 are provided with escapement devices indicated at 5 and these devices are of any usual pattern and are designed to cause the traction wheels 4 to rotate the axle 3 when the said wheels are rotating in a forward direction but should one of the wheels 4 rotate in a rearward direction while the other wheel 4 is rotating in a forward direction, the said devices 5 permit the said wheels to have this rotation without affecting the axle 3. The forward portion of the frame 1 is pivotally mounted upon a truck 6 which in turn is provided with shafts 7. Plates 8 are fixed to the intermediate portion of the axle 3 and are provided at their end portions with elongated slots 9 which are radially disposed with relation to the axle 3. Sleeves 10 are loosely mounted upon the axle 3 adjacent the plates 8 and at their peripheries are non-circular in transverse section. Plates 11 are fixed to the ends of the sleeves and are provided at their opposite ends with slots 12. The slots 12 upon the plates 11 are adapted to register with the slots 9 provided in the plates 8 and when in register bolts 13 are passed transversely through the said slots whereby the sleeves 10 are made to rotate with the axle 3. When the said bolts 13 are removed it will be understood that the axle 3 is free to rotate without rotating the sleeves 10. Chain sheaves 14 are provided at their centers with non-circular openings which snugly receive the non-circular portions of the sleeves 10. The sheaves 14 are con strained torotate in unison with the said sleeves 10 but the sheaves 14 may slide longitudinally along the said sleeves.

An I-beam 15 extends transversely across the frame 1 and at its end portions is connected with the opposite sides of the said frame. Blocks 16 are slidably mounted upon the I-beam 15 for motion longitudinally thereof but are constrained against relative lateral movement upon the said beam. The said blocks 16 are provided with vertically disposed channels which receive the forward flange portions of I-beams 17 which are vertically disposed. Blocks 18 are slidably mounted upon the rear flanges of the I-beams 17 for mo tion longitudinally thereof but are constrained against lateral movement with relation to the said beams. An I-beam 19 is located under the frame 1 and is secured at its ends in brackets 20 which depend from the side portions of the said frame. The blocks 18 are provided with horizontally disposed channels which receive the forward flange of the I-beam 19 whereby the said blocks 18 may slide longitudinally along the said I-beam 19 but are constrained against lateral movement upon the said beam. Arms 21 are carried by the blocks 18 and levers 22 are fulcrumed upon the intermediate portion of the beam 15. Connecting rods 23 operatively connected the levers 22 with the blocks 18 and therefore it will be seen that by swinging the levers 22, the rods 23 will be moved longitudinally whereby the blocks 18 may be shifted along the I-beam 19. Gear segments 24 are mounted upon the I-beam 15 adjacent the levers 22 and each lever 22 is provided with a spring pawl 25 which is adapted to engage the teeth of the gear segments 24 whereby the said levers 22 are held in adjusted positions. Levers 26 are fulcrumed upon the blocks 18 on the arms 21 carried thereby and the working ends of the said levers are connected by means of members 27 with the beams 17. By swinging the levers 26, the said members 27 are moved longitudinally and thus means are provided for raising or lowering the beams 17.

lVhen the machine is used for blocking beets bearings 28 are secured to the lower ends of the beams 17 and shafts 29 are journaled in the said bearings. Chain sheaves 30 are fixed to the shafts 29 and radially disposed arms 31 are also fixed to the said shafts 29. The arms 31 carry at their outer ends spirally disposed blades 32 which when the machine is being drawn along the rows of plants and the said shafts 19 rotate, chop out the superfluous plants in the row.

Brackets are mounted upon the opposite side portions of the frame 1 and shafts 34: and 35 are carried by the said brackets. The said shafts 34: and 35 extend transversely across the frame 1. Chain sheaves 36 and 37 are loosely journaled upon the shafts 34 and 35 and are free to move from one end portion of the shafts toward the other end and vice versa. Brackets 38 are fixed to the inner sides of the beams 17 and carry chain sheaves 39. Brackets l0 are fixed to the outer sides of the said beams 17 and carry chain sheaves 4L1. Endless chains 42 are trained around the sheaves let and 30 and over the sheaves 36, 37, 39 and 411 and are adapted to transmit rotary movement from the sheaves 14: to the shafts 29. Therefore it will be seen that means are provided for spreading the beams 17 apart and for raising and lowering the same. By making provision for spreading the beams they may be so positioned as to carry the knives 32 over the adjacent rows of plants irrespective of the distance between the rows. By providing means for shifting the beams 17 vertically, the knives 32 may be caused to operate upon the plants at the surface of the ground or any desired distance below the surface thereof.

Having described the invention, what I claim as new and desire to secure by Letters Patent is:

1. An agricultural machine comprising a wheel mounted frame, beams carried by the frame and lying transversely thereof, blocks slidably mounted upon the beams, means for shifting said blocks along the beams and securing the same in adjusted positions, vertically disposed beams slidably mounted in said blocks, lever mechanisms for shifting the last mentioned beams longitudinally within the blocks and securing the same in adjusted position, rotating members carried at the lower portions of the vertically disposed beams, and means for opcrating the rotating members from the supporting wheels of the frame by way of the said vertically disposed beams.

2. An agricultural machine comprising a wheel mounted frame, beams carried thereby and extending transversely thereof, blocks slidably mounted upon the said beams, lever mechanisms mounted upon the frame and operatively connected with said blocks to adjust the same along the said beams, vertically disposed beams slidably mounted within said blocks, lever mechanisms operatively connected with the vertically disposed beams, and adapted to shift the same longitudinally and secure the same in adjusted positions, rotary members ournaled at the lower ends of the vertically disposed beams, brackets located at the upper portions of the vertically disposed beams, sheaves carried by said brackets, sheaves journaled upon the frame of the machine, sheaves mounted upon the axle of the machine and adapted to receive rotary movement from the same, and chains trained around the said sheaves and adapted to transmit rotary movement from the axle to the rotary members at the lower ends of the vertically disposed beams.

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