ieaaoas.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed March 13, 1920. Serial No. 365,542.

To all whom it may concern:

Be it known that we, CHARLES M. LONG and MARTIN V. LONG, citizens of the United Statearesiding at hleota and Rock Island, respectively, and in the counties of Keokuk and Rock Island and States of Iowa and Illinois, have invented certain new and use ful Improvements in Weeding Attachments for Cultivators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an attachment for Cultivators and an object of the invention is to'provide a device, particularly adapted for corn cultivators for weeding or pushing or pulling down the weeds around and between the hills of corn and to hold the weeds close to the ground until the shovels of the cultivator cover the weeds.

Another object resides in the provision of an attachment comprising crossing or intersecting tensioned members yieldably mounted upon the beams of the cultivator or depending parts thereof, so that the stalks of corn when grown strong enough may pass between and separate the members whereby the lateral terminals of the members may scratch the hills about the base of the corn stalks, and push or tear down the weeds, and hold them down until the shovels cover them with the soil.

A further object embodies supporting means for the support of intersecting or crossing elements, comprising sleeves mounted upon journals of the supports, and to which springs or tensioned coils of the elements or members are mounted, there being lateral terminals or crooked ends on the coils for engagement with slots of the sleeves, whereby the coils may be easily removed.

A still further object resides in the provision of guides or holders for the tensioned elements or members, to hold them in place in combination with means for tightening up on the sleeves, to increase or decrease the tension of the coils of the elements.

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the in vention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a rear view of a corn cultivator, showing the improved attachment as applied,

Fig. 2 is a plan view of the weeding attachment,

Fig. 3 is a sectional view on line 3-3 of Fig. 1, through one of the supports showing how the supporting sleeve of one of the elements is mounted and also showing the guide or holder for the element, and

Fig. i is an enlarged detail view of one of the crossing elements or members and its coil and showing the sleeve illustrating how the terminal of the coil is engaged in the slot of the sleeve to hold and tension'the element in position.

Referring to the drawings, 1 and 2 designate depending supports, which are carried by the cultivator. These supports depend from the cultivator, and terminate at their lower ends in right angle parts 3 extending inwardly toward each other. The weeding element supporting feet 4 are mounted upon the right angle inwardly extending parts 3 of the depending parts 1 and 2, and each of these feet is U-shaped as illustrated. Suitable bolts 5 pass up wardly through the right angle inwardly extending parts of the supports 1 and 2 and between the opposite sides of the feet. In other words, the supporting feet for the weeding elements straddle the bolts 5 there being washers 6 engaging the upper parts of the feet, whereby the nuts 7 which are threaded upon the bolts can engage therewith. By tightening up the nuts, the feet may be clamped securely between the washers and the upper faces of the right angle inwardly extending parts 8. It is obvious that the feet may be adjusted relatively to the inwardly extending parts 3 in order to set the weeding elements in different positions relatively to each other. If desired, the nuts may be loosened, and the feet moved so that the weeding elements can be disposed out of operative positions, for instance as shown in dotted lines in the plan view of Fig. 2. i

Elongated bolts 8 pass through the forward arched ends of the feet, and mounted upon these upstanding bolts are'sleeves 9, which may be constructed in any suitable proportions and from any suitable material.

In fact, the sleeves may if so desired be out i from pieces of piping of suitable diameter. The sleeves, may be any diameter as may be found most convenient. when manufacturing the device for commercial purposes. Engagingthe upper ends of the sleeves 9 are washers 10, and -.which pass over the upper ends of the upstanding bolts 8 there being nuts 11 th eaded upon. the upper ends of said boltsadapted to be tightened down upon the washers to hold the sleeves in different set positions. Alsoengaging between the opposing sides of the feet are additional bolts 12 having nuts 13 threaded thereon, there being washers 14E betweenjthe nuts and the upper faces of the feet. Weeding elements 15 are provided, and each is in the for'mof an elongated rod, which may be any suitable length in. diameter, constructed from any suitable rod material, and having one end formed into coils 16. The coils of said weeding elements may comprise any number of convolutions as may be found necessary. In the present instance, approximately five convolutions have been found most desirable The rear portions of the weeding elements cross or intersect each other, and terminate in lateral protruding weeding or scratching feet 17. These weeding or scratching feet are beyond the intersecting or crossing point of the arms of the weeding elements. The coils'of theweeding elements are mounted upon the sleevesas disclosed in the drawings. The

- crooked ends 18, which engage slots 19 terminals of the coils of the weeding-elements are. provided with lateral lugs 01;:

the sleeves 9, thereby holding the coils position relatively to the sleeves. It is obvious that by removing the nuts 11 and the washers 10 the coils of the weeding elements may be lifted from engagement with the sleeves. Guides or holders for the weeding elements are mounted upon the bolts 12, between their heads and the under parts of the feet 4. These guides or holders 20 are. inthe form of rods havin eyes 21 through which the bolts 12 pass. holders or guides engages one of the edges of thelateral part 3 of the support, thereby A acting to reinforce the guide or holder in position. The other arm of the guide or holder terminates in a hook 22, which is engaged by the rearwardly. extending part of the weedingattachment. When mounting the weeding elements on the bolts 8, the sleeves are first engaged with the bolts, with the lateral terminals or crooked ends of the coils in engagement with the slots of the sleeves. The sleeves are then posine of the the hooks 22 as shown in the rear view of Fig. 1. As shown the arms of the weeding elements are positioned so that they intersect or cross, as shown in the plan view;

This weeding attachment is used in connection with a cultivator when last cultivating the hills about the basesof the corn, particularly when-the'stalks of the corn are strong enough to causethe weeding elements to separate. In the operation, the cultivator traverses the field, so. that the corn stalks will pass between the weeding attachment. The stalks cause the elements to separate, the lateral terminals 17 acting to scratch the hills about the bases of the stalks of corn and .tear or pull down the weeds,

and hold them sutiiciently until they are covered by the shovels of the cultivator working the soil ofthe hills. In: other words, the shovels work the hills and throw the'soil over the weeds. V Referring to the drawings, it will be noted that there are two sets of weeding elements 15 and 15?. The weeding elements 15 are designed to contact with and fell and drag down the thick and more stubborn weeds by engaging their upper portions. This arrangement is designed to relieve some of the strain upon the weeding elements 15, for the reason that the weeding or scratching feet 17 of the elements 15 are closer to the soil or ground. It will be noted that the feet of the weeding elements 15 are considerably higher above and positioned forwardly of the feet of the weeding elements 15 so as to contact with the weeds or the like higher up in order to more readily start them toward falling position. Whenv this is the case, the scratching feet of the elements 15'will act to subsequently engage the weeds and drag them toward the surface of the ground. It isobvious that these elements and their supporting means may be adjusted vertically, and arranged in other adjusted positions. F urthermore, one or the other of the sets of weeding elements may be dispensed with if so desired for it is obvious that it is not the aim of the present case to unnecessarily limit the protectionof the presentinvention,

The invention having been set forth, what is claimed as new and useful is 1. In a weeding attachment for cultivators, the combination with a cultivatorframe,of a depending support thereon, ad-

vjustable feet carried by the lower ends of pins, weeding elements having coils at their forward portions mounted upon the sleeves and fixed relatively thereto, holders or guides for thecultivating elements and carried by the feet, and means for fitting the sleeves in position in order to tension the rearwardly extending arms of the weeding element.

2. In a Weeding attachment for cultivators, the combination with a cultivator frame, of depending supports carried thereby, of rearwardly extending intersecting yieldable weeding elements, said weeding elements having tensioning means on the supports, and means for regulating the ten sion of the tensioning device, and holders for the weeding elements.

3. In a weeding attachment for cultivators, the combination with a cultivator frame, of yieldable weeding elements extending rearwardly and crossing each other, supporting feet having upstanding rotatably adjustable devices, said weeding elements having tensioning means mounted upon said devices fixed relatively thereto, means for holding said devices in different adjusted positions for regulating the tension of the tensioning means, and holders for the rearwardly extending arms of the weeding elements.

4-. In a weeding attachment for cultivators, the combination with a cultivator frame, of weeding elements extending rearwardly toward and crossing each other and provided with weeding feet, supports having sleeve uprights, said sleeve uprights having slots, the forward ends of the weeding elements having tensioning coils provided with crooked ends engaging said slots for fixing the coils relatively to the sleeve uprights, means for holding the sleeve uprights in different adjusted rotated positions, and holders for the arms of the weeding elements, for tensioning the elements.

5. In a weeding attachment for cultivators, the combination with a cultivator frame, of weeding elements extending rearwardly toward and crossing each other, upright sleeves, supports therefor, means for holding the sleeves adjusted relative to the supports, said supports having guides to be engaged by the weeding elements, the support ends of the elements having tensioning means detachably connected to the sleeves but fixed relatively thereto, whereby upon adjusting the sleeves the tensioning of the weeding elements may be increased or decreased.

In testimony whereof we hereunto aflix our signatures.
