BEET-TOPPING MACHINE.

Application led May 7, 1925. Serial No. 28,683.

My invention relates to improvements in ing wheels 12 at its ends, one `or both of these beet topping machines of the type in which wheels having ratchet connections (not the topping means are carried by an auXilshown) with the axle. iary fiaine inovablyrconnected with the main Loosely mounted upon the axle 11, isa

use, or to permit detachment thereof, for instance when it should be sharpened. rlhe means for springing the legs of the frame outwardly or inwardly preferably consist of a transverse bar 42 arranged between the legs as shown in Fig. 3 of the drawings and the respective ends of which have a right and left hand threaded engagement with said legs. On the projecting ends of the bar nuts may be screwed. Draught links 43 are lpivoted to and extend forwardly from the legs of the frame 38, and the front ends of these links may be connected with the frame 30 in any desired manner. showing, one of the links is pivoted to an arm 44 projecting downwardly from a transverse shaft 44 which passes through openings in the side bars 31, and the other link 43 is pivoted to the lower end of a vertical bar 45 which is secured between its 4ends to the shaft 44. I have shown the upper end of this bar 45 connected with one of the side bars 3l by a strap 46, so that said bar 45 and the shaft 44 are held against movement with respect to the frame 30.

At 47, a shoe is shown in front of the frame 38 and under the frame 80, and in the present showing, this shoe 47 is provided with a pair of longitudinally extending, plate-like arms 48 whose front ends are piveted to a transverse rod 49. This rod is carried by crank arms 50 and 5l which project downwardly from a transverse rock shaft 52 carried by the front end portion of the auxiliary frame 30. The arm 50 is 4preferably formed by the lower end of a hand lever 53 which is secured to the shaft 52 for turning it, so as to move the shoe 47 forwardly or rearwardly, as occasion may demand. An appropriate pawl and rack 54 may well be provided for holding the lever 53 in adjustcd position.

Two rods 55 rise from the shoe 47 at the rear portion of the frame 30 and pass slidably through guide ears 56 carried by a hand lever 57 which is fulcrumed at 58 to a short standard 59 rising from the bar 34. The upper ends of these rods are provided with nuts G0 providing shoulders which engage the upper sides of the ears 56, and the lower sides of these ears are in contact with coiled compression springs Gl which surround the rods 55. rlhe lower ends of the springs Gl may either be connected to the rods 55, or may abut the upper side of the slice 47. ln either instance, when the lever 57 is swung in the proper direction to compress said springs, they will yieldably force the shoe 47 downwardly and will permit slight vertical yiel'ding thereof during operation of the machine, whereas swinging of the lever 57 to the other direction will cause the ears 56 to engage the nuts 60, thus elevating the shoe 47 to the desired adjusted relation, with respect to the blade 41. For holding the le- In the presentr knife 68 has been shown, said knife beingcarried by the lower end of a vertical shaft G4 whose upper end is provided with a pinion meshing with a beveled gear G6 on the shaft 21. rlhe shaft 64 has been shown rotatably mounted in an upper bearing 67 i and a lower bearing (38. rllhe bearing G7 is carried by the center of a transvers-n bar GS) whose ends are preferably bent rearwardly and secured to the bars 28. The hearing 68 is carried by a second transverse bar 7 O whose-ends are forwardly directed as at 7l and connected with the bars 28. The shaft (34 is provided with an appropriate sl'ioul'dcr or shoulders engaging its bearing means to hold it against descent, and it will be seen that by mounting this shaft in the manner shown, vertical adjustment of the auxiliary frame 30 will not affect said shaft or its driving connection with the shaft 2l.

For raising and lowering the frame f as occasion may demand, I have shown a chain 72 whose lower end is connected with the shaft 44, while its upper end is connected with a crank arm 73 on a transverse rock shaft 74 suitably mounted at one side of the main frame, said shaft 74 having an appropriate operating lever 7y o which may be locked in adjusted position by a pawl and rack 7 6.

Preferably used with the parts above described, are two disks 77 which straddle a row of beets to be topped, said disks leing suitably mounted on a transverse bar 78. which is connected by links 79 with crank arms S() and Sl on a transverse rock shaft which is appropriately mounted on the front end of the main frame l. The shaft provided with an upstanding arm S53 connected by a longitudinal link 84 with the lever 75, so that operation of this lever to raise the frame 3l and the beet topping means carried thereby, will also operate the shaft 82 to raise the disks 77. The bar 7S carrying the disks is preferably connectedl with the frame by inclined bars S5 secured to the former and pivoted to the latter.

During the operation. of the machine, the initial topping` knife removes mest of the foliage from the beet tops, the shoe 47 then engages the beets and as it rides over them. it swings the auxiliary frame 30 to properly position the knife or blade 4i'. with respect thereto, and this blade 4l which is being' reciprocated by the frame 3S and pitinan 40, effectively removes all remaining tops freni the beets, leaving them in r adiness to be dug.

Excellent results may be obtained from the general construction disclosed, and it is therefore preferably followed. However,

within the scope of the invention as claimed, modifications may of course be made.
