WEED EXTRACTOR.

Application filed May 27, 1927, Serial No. 194,791, and in Canada April 13, 1827.

This invention relates to improvements in weed extractors and the objects of the invention are to provide a strong, simple and din-ably coilstrinzted mechanism of this descriptiim of light weight and of light draft that will more efficiently perform the funciions reipiiriul of it than weed extracting machines of a similar character heretofore and at present in use.

This invention relates to weed extractors, the essential features of which are substan- 'kelcton rotating drmns including end plans and intermediate plates and a plurality of weed extracting elements in staggered relationship to one another connecting said plates, and means for adjustably securing the weed entracting elements to the plates.

'lcfcrring now to the drawings in which like characters of reference indicate correspomling parts in each figure,

Figure 1 is atop plan view of the machine.

Figure 2 is an end elevation.

Figure 3 a plan view of one of said weed extracting cable elements.

Figure at is an enlarged elevation of the cable partly in section.

Figure .3 is a plan View of one of the discs.

Figure 6 is an enlarged section through the chain tightener.

Figure? is a side elevation of the centre bracket and bar.

Referring more particularly to the drawings, in WlllCll a preferred example of my invention is disclosed, 1O designates the machine frame supported on wheels 11 and 12 in turn mounted on rotatable stub axles 13 and 14; journalled in the frame. These axles carry gear wheels 15 and 16 connected by chains 17 to the gears .18 keyed on a transi ersely extending shaft 19 and said chains intermediatcly travelling over an adjustable tightener 20 consisting of a slotted upright 21 rigidly connected to the frame 10 and having a screw-threaded spindle 22 adapted to move upwardly and downwardly therein and to be retained in position when adjusted by the loclonnts 23. On the other end of this spindle is a sprocket wheel 24 engaging with the chain 17 so that as the spindle is moved upwardly the chain will be tensioned (see Figure 2) and on being moved downwardly the chain will slacken.

Substantially midway of the width of the machine is mounted a supporting bracket 26 of special formation (see Figure 7) connect ed to which is a bar 27 to which the hitching means 29 and 30 are connected in any well known manner at 31 and Rigidly mounted on the shaft 19 and adapted to rotate therewith are the weed extracting elements forming an essential feature of my invention comprising plates 33 and 34: and 35 and 36, the end plates and 36 being adjacent the outer ends of the frame 10 and the plates 3% and 35 being adjacent to the centre bracket 26.. Intermediate of these pairs of plates are intermediate plates 37 and 38 with peripheral openings therein similar to openings 40in the end plates.

Connecting the end plates and intermediate plates and adapted to be anchored in the openings in the end plates and intermediate plates are the weed extracting means comprising wire, cables, chains or rods 41 and formed, as itlusirated in Figure 3, with nip pics 42 brazed or otherwise connected onto the end of the cable, one of the nipples being screw-threaded at 43 to engage with a retaining nut 4%, the other nipple engagim with the peripheral openings in the em plates 33, 34, 35 and 36 (see Figure 1). In this way the members 41 can be tensioned or slackened at will.

A feature of the arrangement of these weed extracting members 41 is that they are in longitudinal alignment and in staggered relationship to one another so that they are al-.

ways in operation in contact with the ground to more efficiently perform the functions required of them.

In operation and as the machine moves forward the sprockets 15 and 16 are rotated through the chains 17, the sprockets 18 on opposite ends of the shafts l9 rotating the latter and with it the different sections of skeleton drums of the weed extracting means. Due to the sprocket ratios the skeleton drums make one revolution for every three. and a half revolutions of the wheels 11, thus giving the cable extracting means a retarded action so that they enter the ground with a forward motion, remain in the ground for a (listance of approximately six feet and then emerge from the ground behind the skeletion drums and deposit the weeds on the surface.

If desired the weed extracting members may be provided with auxiliary means in the form of teeth or spurs or any other suitable device for engaging with and collecting the weeds.

hen it is desired to throw the shaft and the weed extracting members out of gear the clutch 45 on the stub axles 13 and 14: may he brought into action.

From the foregoing it will be seen that my improved weeding machine is of simple and durable construction, of light weight and draft and adapted to ellieiently perform through its different eo-ordinating parts the functions required of it.

As many changes could he made in the above construction and many apparently widely dillerent embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter eontained in the aemmpanying s 'iecilication and drawings shall he interpreted as illustrative and not in a limiting sense.

hat I claim as my invention is:

1. In a machine of the elmraeter described a rotatable shaft, a plate rigidly mounted at each end of the shaft and formed w'th. peripherally spaced openings therein adapt ed to engage with a wire or the line, a pair of oriliced supporting plates rigidly mounted on the shaft substantially midway there of, orificed plates rigidly mounted on the shaft intermediate of the pair of supporting plates and the end plates, the peripheral openings in the last inentii'med. plates being in staggered relationship to the openings in the end plates a plurality of flexible weed extract/iire elements such as wire anchored. at one end in the end plates and at the other end adjustahly engaging; with the plates hetween the end plates and the supporting plates, a plurality of weed e\traciting ele ments mliustahly eonneeted to the plates be tween the end plates and the supporting plates and extending through the supporting, plates, and retaining nuts "For said elements.

The intention arrording to claim 1 in Which the ad iustahle e1 rinp; means for the weed extracting elements comprise threaded i'iipples-i on the ends of said elements adapted to engage with the openings in the different plates and to he retained in position hy means of nuts or the like.

In witness whereof l have hereunto set my hand.

RITQSELTJ MILLS.
