WHEELED WEEDER.

Application filed December 23, 1926. Serial No. 15 ,717.

This invention relates to weeders and particularly to thoseweeders which embody a wheeled supporting bar and a cutting blade mounted upon the bar and extending longitudinally thereof.

The general object of the present invention is to provide a construction of this character with means whereby to secure positive control of the cutting blade in forcing it into the ground and adjusting it to' the required depth of cut, this being particularly necessary where the ground is not. uniformly packed.

Another object is to provide means whereby, when the cutting blade is locked in one position, .it is controlled throughout its entire extentso that every portion of the cutting blade is raised or depressed simultaneously except for the slight'difference due to torsional stress placed upon the beam on which the cutting blade is mounted.

Still another object is to provide 'improved means for supporting the main frame of the weeder and rotating it on the wheel spindles when the cutting bladeis being raised or depressed, thus reducing the weight handled by the lever to a minimum.

till another object is to provide a weeding machine of this character formed in two sections hinged to each other so that one section may be turned over upon the other section, thus making it possible to fold the weeder into compact form formoving, and

another object in this connection is to pro vide a trailersection and so connect the trailer section'by a hinge or pivot to the main beam or frame, that the hinge will turn on the same points or in line with the pivot points of the beam itself.

A further object is to so construct the weeder that the'goose-necks or curved brackets supporting the cutting blade are mounted on top of the beam. which constitutes the main frame, thus giving a much larger throat than is otherwise possible. This has been found of great advantage in reducing the obstruction offered by the goose-necks to the passage of weeds, straw, and the like.

A still further object is to provide a construction of this charac'ter which has relatively few parts,'which is exceedingly simple, which, reducesfdraft, and which permits the weeder to be dumped for its full length with but little effort. I

My invention is illustrated in the accompanying drawings wherein Figure 1 is a top plan view of a weeding machine constructed in accordance with my invention i Fig 2 is a rear elevation of the weedin machine, the bars connecting the trailer wit the main frame being in section;

Fig. 3 is a section on the line 33 of Figure l; i r

Fig. 4: is a fragmentary section 'on the line 44t of Figure l.

Referring to these drawings it will be seen that the main frame of the weeder includes two longitudinally extending beams 10 and 11 which may be of wood or any other suitable material, these beams at their outer ends supporting the wheels 12. To this end the wheels 12 are mounted upon the wheel spindles 13, these spindles extending beneath the beam and being engaged therewithbyf the U-bolts 14. I dov not wish to belimited to this as other means might be used for supportin the wheels.

The inner'endof the beam orfsection 10 also carries a wheel 15 which is mounted upon a wheel spindle 16 which extends beneath the beam and is bolted thereto or otherwise engaged therewith as, for instance, by the U-bolt 17 'Attached to the side faces of the beam 10 are the upwardly and laterally inclined brackets 18 which are divergent withrelationto each other and mounted upon the inner end of the beam 11 are like brackets 19 whose ends overlap the brackets 18 and these overlapping ends are pivoted to each other by means of the bolts,

rivets or pivot pins '20. Thus, it will be tratedin dotted lines in Figure 2, a supporting member 21 being mounted upon the beam 10 adjacent the upper. end thereof and upon which the beam 11 rests when the beam 11 is folded over. 1

Mounted upon the beams 10 and ll are any desired number of rearwardly extending, downwardly curved goose-necks or draw bars 22. These are illustrated as attached to the upper faces of the beams by means of U-bolts or other like means 23. Attached to the goose-necks or draw bars 22 of the beam 10 is a scraper blade 2a and carried by the goose-necks of the beam '11 is a like scraper blade 24. These blades overlap on a plane intersecting the pivot 20 and preferably the meeting ends of these blades are beveled or angled as at 25, see Figure 1, so that the two blades when both are in use, constitute practically one long blade having a length somewhat greater than the combined lengths of the beams 10 and 11.

Disposed rearward of the beam 10 and adjacent the inner end of this beam, is a trailer consisting of a platform 26 having mounted thereon the seat supporting frame 27 and the seat 28 with its foot rest 29. This'platform 26 isconnected to the beam 10 by means of the two downwardly and forwardly extending draft bars 30. These draft bars 1 30 extend downward below the beam 10 and then upward and are pivoted to ears 81 at tached, to the beam and projecting slightly below the same. Thus the beam and the trailer arepivotally mounted to each other so that the beam may rotate on. the axes of the spindles 16 and 13 and obviously an oscillation or rotation of the beam 10 will cause a like oscillation of the beam 11.

vFor the purpose of oscillating the beam 10 I mount upon the platform 26 the lever 32 which is pivoted at 33 and carries an arm 84 projecting forwardly and connected by a link 35 to the arm 36 attached to the under face of the beam 10 and projecting rearwardly therefrom. The lever 82 operates over a rack 37 and the lever is provided with the usual hand operated bolt 38 whereby the lever may be engaged with the arcuate rack vat any desired point. By shifting the lever 32 rearward, the scraper blades 24 and 24 will be raised by tilting the beams 10 and 11, and by shifting the lever forward, the blades will be depressed. Thus the depth of cut may be regulated or the weeding blades may be lifted entirely off the ground and t0 the position shown in dotted lines in Figure 2. It is to be particularly noted that the goosenecks 22 are mounted on top of the beams 10 and ll, to thus leave a larger throat or space between the beams 10 and 11 and the 10 and 11.

the beams 10 and 11, as shown in Figure 4, with the eyes disposed in line with the pivotal center or axis of the spindles 13 so that there is no tendency for the draft to pull the cutting blade either into the ground or out of the ground.

It will be seen that the weeder when being dumped, rotates on the spindles of the supporting wheels. This permits a ready adjustment of the blades without any resistance to their movement. The hinge between the two sections of the weeder frame provides a flexible joint which allows the two blades to adapt themselves to any uneven surface over which they may move but at the same time the two sections are held rigidly in alignment with each other and with reference to the line of draft. The weeder may be made in any length desired up to a practical limit and while I have illustrated a weeder formed in two sections, 1 do not wish to be limited to this as a third section may be added, the middle section under these circumstances being provided with a wheel on each end and a hinge at each end to which the end sections may be connected. In thiscase, the trailer section would be connected to the middle section, preferably at the middle thereof, in a manner similar to that shown in the drawings. It is obvious that many changes may be made in the details of construction and arrangement of parts which I have illustrated without departing from the spirit of the invention as defined in the appended claims.
