WEEDER.

To all whom itmay'concern:

Be it known that 1, DAVID B. WoLroRD, a citizen of the United States, residing at Nolin, in the count'y of Umatillaand State of Oregon,'have invented certain new and useful Improvements in \Veeders, of which the following is a specification.

My invention relates to an agricultural implement and particularly to a weeder.

My main object is to provide a Weeder of simple construction which is capable of manufacture at low cost and which will prove durable and effective in use.

"Specifically, I aim to provide an implement of this type wherein the weeder proper maybe adjusted and maintained atdifferent heights; one wherein arevoluble weeder may be employed which is adapted to be fastened against rotation but which is permitted 'to rotate under certain conditions, and to provide a weeder of such construction that it maybe satisfactorily used in gang formation.

' of one of the 'Weeders; tion of one of the weeders;

With the above and additional objects such as will hereinafter appear, in view, the invention has been'embodied in one preferred form as hereinafter described and illustrated in accompanying drawings wherein z- Figure '1 is a plan view of a plurality of weeders, one of which is shown fragmentarily'; Fig; '2 is front elevation of the weeders of Fig. 1; Fi 3 is a rear-elevation Fig. 4 is a side-eleva'- Fig. Bis a cross section on the line"5-5 of is a perspective view of one of the auxiliary weeders employed; Fig. "7 is a plan View of the abutment or trip means for the turnable weeder; Fig. '8' is a side elevation of'the parts of'Figj'? and'Fig 9 is a cross sectional View onthe line 99 of'Fig. 8.

Referring specifically to the drawings, wherein like numerals designate like or similar parts in the differentifigures, I first provide a suitable sled or truck-whichmay be composed of runners '1 preferably having metallicrunners proper at 2 to directly engage the soil, and a connecting beam 3 mounted on the runners 2 adjacent their front ends and secured to'the runners as by means of bolts 4:.

A superposed supporting frame is generally shown at B for a w-eeder or the like as illustrated at C. Weeder C is turnably mounted by means of a shaft 5 of suitable construction, for instance, of a section of Specification of Letters Patent.

metallic pipe, and is journaledin'side beams f the frame B.

It is to be understood that the weederG may be of any approved form. However,

I find it advisable to use the form illustrated and which consists of'a suit-able number of traction elements or wheels 7 suitably keyed to the shaft 5 and having tangential cutting blades or weeding blades 8 riveted or otherwise'fastened to the traction elements at 9. It'will be noted that theseblades are preferably sharpened to a point at 310 and that their rear edges are blunt as at 11 and are arranged to terminate at diametrically opposite points of the center of the weeder C. However, it is obvious that a greater nuinberof blades maybe provided, if desired. lVeeder C is fastened against undue movement laterally of beams 6 by means of collars 12 secured to the shaft 5.

superposed on the beams6 and extending at right angles thereto, are one or more beams 13 on which rest adjacent the centers .and transversely thereof, short beams '18 Bolts 15 pass through the beams 13,13 and 14. Beams 12L at-their front ends rest upon one or -m0re blocks 15 supported upon beam 3. r

.The frame 'B is capable of movement as a Whole vertically relatively to the truck so as to vary the height of the weeder C. To this end, beams or runners 1 :are connected to the beams 6 by adjustable bolts 16; the beam 3 and-blocks 15 andbeams 14 are connected by adjustable bolts -17, and runners 1,'beams 6 and beams 31 are :connected'by It may be mentioned that'beams-13, 13 and'l t are connected by bolts 19. When bolts 16, 17 and 18 have their'nuts loosened, beams'o may beraiscd on the runners 1 and insert strips 20 inter posed intermediatethe runners 1 and beams on which restcro-wn beams 1ft. 7

in detail in Figs. 7, 8- and '9. This means may. comprise parallel plates '22 disposed intermediate the beams inner faces thereof, being fastened against displacement by bolts 23 and 2 1. Pivotally mounted intermediate the plates 22 and on 14 and against the.

' pedal 31, draws the latch 27 rearwardly and the bolt 23 is an abutment arm 25 adapted to be fastened against or in abutting relation with the bolt 24 and being normally urged into such position by means of a coil spring 26 fastened to the arm 25 and to one of the beams 14 for convenience. 00- operating with the arm 25 is a latch '27 pivoted to the plates 22 by means of a bolt 28, having an angle arm 29 to directly engage the. abutment arm 25 mally urged into such position by a coil spring 30 secured to'the latch and for convenience, to one of the plates 22. Latch 27 is preferably foot operableand to this end is provided with a lateral foot rest or pedal 31, preferably disposed adjacent a suitable operators seat 32 which may be mounted by a bracket 33 from the beams .lt'.

Vfith the parts of mechanism D inthe re lation shown in the drawings, -the weeder (Twill be held against upward turning movement by the abutment of the rear edge with the element of the uppermost blade which is maintained rigid and against movement by bolt 2. 1 011 one side and arm 251 of latch 27 on the other side. desirable, in some instances, to permit the wee'der to make a halt turn, as for instance, when an obstacle in the soil is encountered, ortrash or other material is dragged by the lowermost blade. In such an instance, the root of'the operator by engagement with out of the pathof movement of abutment 25, particularly at arm 29 whereupon "the weeder may turn, swinging arm 25 on pivot 23 as it passes same. After a blade 10 travels past the abutment spring 26 restores the abutment or arm .25 to vertical position, after which the operator removes his toot fromenp'a ement with latch 27 ermitting spring to restore arm 29 of the latch nto engagement therewith as seen 1n Fig. 8 so that whenthe other blade strikes arm'25 it will serve as a rigid abutment.

It is obvious that any suitable draft means may be connected to the implement. r

In some instances, I may prefer to arrange the implements in a connected series or gang as suggested in Figs. 1 and 2. To this end, hinge leaves or bars34exte'nd laterally irom ends of the truck or sled and have register ing eyes receiving horizontal'pivots 35 flexibly connecting the sections for vertical movement. The pivotalconnection enables the different implements'of a gang to better accommodate usage on uneven ground. 7

' 'It will berealized that in the absence or weeding means covering the path intermediate elements C of a gang of implements, such and being nor.-

It. may be in presence of two witnesses. g v I 7 DAVID, BgwoLroR path would remain in its original condition.

In view of thisfact, I provide a plurality of weeders in the form of Fig. 6, each having an angularly disposed scraping blade 36 sharpened at its scraping edge 37 and being 7 Itis preferred that and '36 project a inorder to cut the weeds as the implement is drawn along, at or adjacent their roots.
