PEANUT BIGGER.

Application filed September 7, 1926.

The present inventionrelates to a peanut digger, and has for its prime object to provide a structure wherein a pair of wheeled frames are connected and have means associated therewith so that the rear frame may be adjusted in relation to the front frame for controlling the depth of the digging element mounted on said rear frame.

Another very important object of the invention lies in the provision of a device of this nature which is exceedingly efficient and reliable in digging peanuts and which will leave the soil in excellent condition for clover, grain, or the like.

A still very important object of the invention lies in the provision of a peanut Vdigger of this nature which is exceedingly simple in its construction, inexpensive to manufacture, easy to manipulatein its adjustment, strong and durable, and otherwise well adapted to the purpose for which it is designed.

Vith the above andnumerous other objects in view as will appear as the description proceeds7 the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of the peanut digger embodying the features of my invention, showing a portion in section,

Fig. 2 is a top plan view thereof,

Fig. 3 is a detail vertical section taken substantially on the line 3-3 of Fig. 2, and

Fig. 4: is a detail perspective View of the digging elements.

Referring to the drawing in detail, it will be seen that the numeral A denotes the front frame and the numeral B the rear frame. The front frame A includes a substantially horizontally disposed plate 5 mounted on an inverted U-shaped axle structure 6 on which are journaled wheels 7. A draft tree 8 is en-` gaged on the front end of the plate 5 by means of a bracket 9. Braces 10 extend from the front end of the plate to the extremities of the axle structure 6. An arcuate slot 11 is formed in the rear of the plate 5 and extends transversely thereof. The rear end of the bracket 9 terminates in a loop 12 whichis engaged in an eye `14; formed in the forward end of a plate 15 slidable on the rear portion of the plate 5.

A bolt 16 extends from the plate l5 Serial No. 133,983.

through the slot 11. The slot 11 is concentric in relation to the loop- 12 so that the plate 15 may swing in an are on the plate 5. A riser 17 is preferably cast integrally with the plate 15 and has a vertical rear portion designated specifically by the numeral 18 and provided with a vertical seriesy of openings 19. A lever 20 is pivotally engaged with one of the openings 19 by means of a pin 21. A pair of curved rods 22 is enlgaged as at25 intermediate their ends with a toothed segment 24. There is one of these rods 22 on each side of the segment 24 and they extend rearwardly and outwardly, and downwardly, as is clear from an inspection of Figs. 1 and 2. The forward ends of the rods 22 straddle the riser 17.

A detent 26 is associated with the lever 20 for engaging the toothed segment 24. Auxiliary rods 27 are engaged between the rods 22 and with the'toothed segment 24 at 25 and extend downwardly and further rearwardly than the rods 20.

Therear frame B includes a pair of parallel spaced beams 28 from which rise sides 29. The forward ends of the sides 29 and the beams 28 are engaged with the lower ends of the rods 22 and 27 as is indicated at 30. A bracket structure 31 includes Va plurality of legs having their extremities attached to the beams 28 and on the upper portion of the bracket structure there is disposed a seat 82.

An axle 33 is fixed as at 34 to the beams 28 to extend transversely under the rear portions thereof and under the seat 32. The beams 28 normally incline downwardly and forwardly in respect to the axle 33. A digging element is denoted generally by the letter D and is in the form of a blade having its longitudinal edges converging from intein mediate points forwardly to a point 35. The rear portion of the blade is bent longitudinally and provided with longitudinally extending slots 86 forming scattering tines 87. The blade is further provided with a pair of openings 38 one adjacent each side edge intermediate the ends thereof for being pierced by bolts 39 which pierce suitable openings in the forward ends of the beams As the implement is being pulled vforwardly, it will be seen that by proper manipulation of the lever 80, the digging element may be adjusted in respect to the ground as may be desired so that the peanuts may be dug therefrom and the peanuts and soil Will be moved upwardly on the blade and somewhat scattered by the tines 37, so that the peanuts may be ,easily gathered from the broken up soil. The machine Will leave the soil in an excellent condition for grain, clover, and the like.

ith this machine, it is only necessary to go over the row once, because the digging element may always be maintained at the proper depth.

It is thought that the construction', operat-ion, and advantages of this invention Will now be clearly understood by those skilled in this art Without a more detailed descrip'- tion thereof. The present embodiment of this invention has been disclosed in detail merely by Way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention andthe above description; It -Will be apparent that numerous changes in the details otl construction, and in the combination and arrangement of parts may be resorted to Without' departing from the spirit or scope of the invention as hereinafter claimed, orV sacrilicing any of its advantages.

Having thus described my invention, What Il claim as new is:-

An agricultural digging device of the class described including in combination, a front Wheeled frame, a' casting on said frame, a lever pivoted to said casting, a toothedrsegment pivotally engaged with said Vlever at an intermediate portion thereof, al detent on said lever engageable With said segment, rods havii'i'g intermediate portions fixed"Y to the seg-ment, their forward enfds straddling the cast-ing, their rear ends' extending dow-n- Wardly and outwardly, a` rear Wheeled 'frame including a pair ot parallel spaced members attached at their forward ends to said' rods7 an aXle extending across the rear portion of said means, and having Wheels journalled thereon, a blade fixed tothe forward portions of themea'ns.

In testimony whereof I aiiix my signature-u ononenn. omar/JARD.
