To @ZZ whom t may concern:

Be it known that I, HILRY BURR NoLEN, a citizen ofthe United States, and a resident of Lamar, in'the county of Walla Walla and State of Washington, have invented a new and Improved Weed-Cutter, of which the folp lowing is a full, clear, and exact description.

This invention relates to weed-cutters such as used on farms for cultivating fields.

The object of the invention is to produce an implement of this class which is of simple construction and provided with a plurality of cutters the position of which may be readily adjusted.

The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan of the machine, the tongue being represented as broken away. Fig. 2 is a side elevation, the tongue being represented as broken away. Fig. 3 is a cross-section taken on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal section taken on the line'4 4 of Fig. l and upon a slightly-enlarged scale. Fig. 5 is a detail illustrating the man'- ner of attaching the cutters or knives to their brackets. This view is a vertical section, and the upper portion of the bracket is represented as brokenaway; and Fig. 6 is a plan view of one of the knives.

Referring more particularly to the parts, l represents the main frame of the implement, which is of rectangular form, as shown, and provided with a main beam 2, which extends longitudinally of the frame and transversely with respect to the tongue 3, which attaches to the forward member of the frame. The tongue 3 is preferably secured rigidly in position by diagonale or braces 4, arranged as shown. At right angles to the main beam 2 a tongue-beam 5 is provided, which is disposed centrally of the machine and virtually constitutes an extension of the tongue 3, attached, as it is, at its forward extremity to a bracket 6 at the rear of the tongue, as shown. The main beam 2 and the tongue-beam 5 are preferably mortised together at their point of intersection, as. indicatedat 7 in Fig. 3. At the extremities of the main beam 2 spindle irons or arms 8 are attached, which project downwardly, as shown, and are attached rigidly to spindles 9 at their lower extremities. Upon these spindles 9 wheels 1.0 are mounted, in connection with which dust# proof boxes 11 are arranged, as indicated. The vertical extensions of the arms 8 afford means for guiding the drop-frame 12, which is of rectangular form, as indicated, and is of substantially the same dimensions as the main frame 1. This frame is provided with a central beam 13, which runs in a front and rear direction directly below the tonguebeam 5, referred to above. Preferably near the point 7, which is the ljoint between the beams 2 and5, there is mounted a quadrant 14, upon which is mounted a main lever 15. This lever 15 is preferably constructed of two bars 16, attached on opposite sides of the quadrant, supporting links 17 at their lower extremities, said links preferably having a common pin 18. These links 17 afford means for supporting the drop -frame, the lower extremities of the said links being attached pivotally to the central beam 13, as indicated at 19 in Fig. 3.

As will appear most clearly from inspection of Fig. 4, the vertical extensions of the spindle-irons 8 lie adjacent to the outer faces of the end members of the drop-frame, and these members are provided with guidebrackets 20, which make a loose lit therewith, as will be readily understood. While this main lever 15 affords means for raising and lowering' the drop-frame for a purpose which will appear hereinafter, other mechan- `ism is provided for tilting the drop-frame intoany position desired. This latter mechanism will be described hereinafter.

It should be understood that the dropframe carries the cutters or knives 2].. In Order to facilitate their attachment, the dropframe is preferably provided with diagonale or diagonal bars 22. These bars are arranged in pairs on each side of the central axis of the implement, extending from thc middle of the machine outwardly toward the rear. These beams are arranged parallel, as shown, and to their under sides the shares or brackets 23 of the cutters 21 are attached. In, the illustration T show five cutters; but there may in practice of course be as many of these as desired. `I prefer, however, to arrange them symmetrically, as indicated. The brackets 23 preferably taper toward their lower extremities and are formed, as indicated most clearly in Fig. 5, with forwardly-projr-xcting toes 24. These toes pre- IOO IOS

sent substantially flat horizontal upper faces to which the cutters 21 attach. The cutters or knives are preferably substantially V- shaped, as shown, the vertex of the V being disposed forwardly and the central axis of the V lying upon the front and rear line. The form of the forward portion of these knives is most clearly shown in Fig. 6. At this part each knife is formed with a notch y25, which is adapted to receive the forward edge of the shank of the bracket to which it attaches. It should be understood that this notch 25 fits the shank of the bracket nicely, so that the rigidity of the attachment is increased, while at the same time the forward portion of the knife is rigidly attached to the toe by a bolt or rivet 26. This construction is considered highly advantageous.

To the forward member of the drop-frame 12 I attach near the central point inwardly converging links 27. These links extend downwardly, as shown, and are attached at their rear extremities to anchor-plates 28, as will be readily understood. Their forward extremities attach to a swingletree 29, which they assist in supporting. ln addition to the links 27 a chain 30 is provided, which extends down from the under side of the tongue, so as to support the swingletree, as will be readily understood.

lt should be understood that the links 17 support the principal portion of the weight of the drop-frame, but arrangement is made for tilting the drop-frame into any angle desired. For this purpose near the four corners of the main frame l attach quadrants 31, with which levers 32 cooperate. From the short arms of these levers links 33 are suspended, the pins of the arms lying in longitudinal slots 34, formed in the links, as shown. The lower extremities of these links attach to the drop-frame pivotally at the points 35.

The lever 15 and all the levers 32 are provided with locking mechanisms 36, including the usual bolt coperating with the teeth 37 of the quadrants. With this arrangement while the links 17 are supporting the dropframe either the forward or rear members of the levers 32 may be locked in a depressed position. If the rear members are locked in l a depressed position with their short arms elevated, they will raise the rear portion of the drop-frame, and vice versa. In this connection it should be understood that there is ample play at the brackets 20, permitting the mode of operation described.

At a suitable point, preferably at the rear of the main frame 1, a seat 3S is mounted, upon which the driver of the implement sits said main frame thereabove,

in driving the horses to which the implement is hitched, and in a convenient position a foot-rest 39 is provided, which attaches to the tongue-beam in any suitable manner.

In the operation of the machine it should be understood that it will pass across the field with the drop-frame adjusted to the proper height to cut the weeds as the implement advances. The cutters or knives 21 would preferably be disposed just below the groundlevel. The extreme width of the knives at their rear is great enough and their arrangement is such that, in effect, every point pass ing beneath the frame is passed over by a cutting edge. ln this connection it should be understood that the outer edges 4() are the cutting edges of the knives.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- 1. ln a machine of the class described, in combination, a substantially rectangular main frame having a transverse beam and a central beam, a quadrant supported near the intersection of said beams, a lever coperating therewith, a substantially rectangular drop-frame below said main frame, means for freely guiding said drop-frame upon said main frame, a link supporting said dropframe from said lever, links attached to said drop-frame and having slots, quadrants carried by said main frame and levers carried by said last quadrants and attached in said slots.

2. In a machine of the class described, in combination, a substantially rectangular main frame having a transverse main beam and a central beam, spindle-irons attached to the extremities of said main beam and having downwardly-disposed extensions, a drop -frame disposed beneath said main frame and having brackets adapted to slide on said extensions, means for supporting said drop-frame from said main frame near the point of intersection of said beams, wheels carried by said spindle-irons, links attached to said drop-frame, quadrants attached to and levers on said quadrants coperating with said links to tilt said frame, said links having slots at which said levers attach.

ln testimony whereof I have signed my the presence of Y name to this specification in two subscribing witnesses.
