tion I provide a plurality of cutting edges which ma be selectively employed and in order to prevent rapid drying out of the ground I provide a roller which is adapted to cooperate with the cutting edge employed. My structure allows of various working combinations which will be evident from the following detailed description with reference to the accompanying drawings in which:

Fig. 1 is a side elevation of the weeder reattached to'a hand cultivator frame,

Fig. 2 is a top plan view of the weeder,

Fig. 3 is a longitudinal section of same on line 33 of Fig. 2 and,

Fig. 4 is an end view of the weeder showing the knives in a different relation.

Referring to the drawings, 1 represents the wheel of the cultivator and 2 the handles carried thereby. A depending tongue 1:3 is provided and is attached by bolts l to the handles and is braced by means of a member 5 attached thereto at 6. At its lower end the tongue consists in the usual manner of two spaced elements as shown at 7, Fig. 2. The U frame 8 which serves for supporting the weeder elements is adapted to be attached to the depending tongue elements 7 by means of a bolt 9 insertable there between. I also provide a coupling element 10 having the claws 11 which cooperate with the tongue in order to'provide a rigid connection between it and the frame 8. As will be seen from the drawings the member 10 is held by bolt 9 with its claws ll resting on the edge of the frame element 8 so that no relative twisting movementbetween the two is possible. Pivoted to the frame 8 near its shoulders by means of bolts 12. are the arms 13 and-M which are preferably integral with the horizontal knives 15 and 16 respectively. As will be seen the arms 13 are longer than arms let anc the knife 15 is longer than the knife and both of the latter are provided with double edges. In its operative position the frame 8 is of course substantially horizontal and as will be seen from'Figs. l and 3 one of the knives is disposed above frame 8 and the other below the same. The position of the knives is determined by the rigid spacers 17 and 18 connectingthe frame with arms 13 land 14 respectively. In order to vary the angular position of the arms 13 I and let relativetothe frame 8 the spacers l7 and 18 are provided with a plurality of spaced apertures whereby by means of the bolts 19 and 20 they may be variably attached to the respective arms. Pivoted at the end of the frame 8 by means of bolts 21 are the depending arms 22 attached at their other ends to the axle 23 of a roller 24. The bolts Qialso serve for attaching arms 17 to the frame 8.

The device is shown in Fig. l with the knife 15 inworkmg p0s1tion,.that is, in a lower position relative to theframe 8, and

.thus. its forward edge is in a position to effect a sub-surface cutting action- At the same time roller 24: depends from frame 8 in a position immediately behind the knife 15. Now if it is desired to adjust the weed er for a narrower swathe the bolt 9 is loosened and the frame 8 turned through 180. This will bring the knife 16 into opcrating position and at the same time by force of gravity the roller 24 will come into a position to cooperate with this knife. If it is desired to accomplish a plural weeding action the knives maybe brought into the parallel position shown in Fig. 4. The fact that arms 1% are shorter than arms 13 allows this relative positioning of the two knives; otherwise, and if it is not desired to use double cutting edges, the two sets of,

arms may be made of equal length or in any desired proportion.

It is evident that with the weeder assembled in the manner described onl the for ward edge of each of the knives will come into use. However, when these edges become dull. by merely removing bolts 19 and 20 the arms 13 and let may be swung so that the disposition of knives l5 and 16 relative to the frame 8 is reversed and thus the other edge of each of the knives will be presented in working position. 7

Having thus described my invention I claim:

l. The combination of a weeder comprising a plurality of horizontal knives, a common carrying-member for said knives, said carrying-member being swingable on a horizontal axis transverse to the longitudi nal direction-of the knives for bringing the latter selectively into working position, and
