MILTON JOSEPH ANDERSON, OF DUFUR, OREGON.

WEED-DESTROYE'R.

senemmmen forming part of Letters Patent No. 6 0,612. dated October so, 1900.

Application filed January 5, 1900- Serial No. 503. (No model.)

To all whom, it may concern:

Be it known that I, MILTON JOSEPH AN- DERSON, a citizen of the United States, residing at Dufur, in the county of Wasco and State of Oregon, have invented a new and useful Weed-Destroyer, of which the following is a specification.

My invention relates to weed-destroyers of the class disclosed in my prior application for Letters Patent, filed February 18, 1899, Serial No. 704,904.

The present improvements are directed, first, to a novel construction of one of the weed-cutter shares and an improved arrangement of the weed-cutter shares by which the weeds and trash severed by the cutters are thrown in opposite directions in order to lighten the draft on the machine, and, secondly, to an improved construction and arrangement of parts for raising and lowering the cutter-carrying frame without affecting the position of the seat-frame.

With these ends in view the invention consists in the novel construction, arrangement, and combination of parts, which will be hereinafter fully described and claimed.

To enable others to understand my improvement, I have illustrated the same in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a perspective view of a weeddestroyer with one of the carrying-wheels removed, showing the present improvements embodied in the machine. Fig. 2 is a plan View of the machine, illustrating the relation of the oppositely inclined series of single weed cutting knives relative to a doublewinged central cutter. Fig. 3 is a longitudinal sectional elevation taken in the plane indicated by the dotted line 3 3 of Fig. 2. Fig. 4 is an enlarged detail horizontalsectional view of the means for pivotally connecting an arm of the cutter-carrying frame to the seatframe. Fig. 5 is a detail perspective View of a hanger for the cutter-carrying frame. Fig. 6 is a detail perspective view of the doublewinged central cutter detached from the machine. (Shown by Figs. 1 and 2.)

The same numerals of reference are used to indicate like and corresponding parts in each of the several figures of the drawings.

10 designates an ordinary seat-frame conin raising or lowering the cuttercarrying frame; but in the present machine I employ a singleaxle which extends the full width of the seat-frame to have the wheels supported directly on the ends of said axle, and the cutterframe is connected pivotall y with the seat- .frame by devices which turn on centers afforded by the axis of the Wheeled axle.

The axle 13 is a single bar of metal, square or polygonal in cross-section, except at its ends, Where the axle is made of cylindrical formation to produce the Wheel-spindles 14, and the length of this axle and its spindles exceeds that of the seat-frame in order that the end portions of the polygonal or squared length may extend beyond the end rails of the seat-frame. The carrying-wheels lo are fitted loosely on the spindles to occupy a spaced relation to the end rails of the seat frame. construction and confined on the wheel-spindles by any usual devices.

. The cutter-carrying frame 16 is similar to the machine of the former application, and

'it consists, preferably, of a metallic bar having its ends bent to form the forwardly-ex- These wheels may be of the usual.

tending arms 17, said frame arranged to lie at the rear portion of the seat-frame for its arms to extend toward the axle 13. I resort to the employment of the frame-hangers 18 (shown more clearly by Figs. 4 and 5) to "connect the cutter-carrying frame to the seatframe and the axle 13. Each hanger is cast in a single piece of metal to form a sleeve 19 and a shank 20, the axis of the sleeve being at right angles to the length of the shank. This sleeve is provided with a longitudinal polygonal opening 21, the cross-sectional area 4 of which corresponds substantially to that of the polygonal section of the axle, and this Y sleeve is furthermore provided with an annnlar groove 22, which forms the spaced shoulders or collars 23. The shank of the hanger is formed with a longitudinal groove 24 in one of its side faces, said groove terminating in an abrupt shoulder 25 at the line where the shank joins the sleeve. The hanger has its shank applied to the free extremity of an arm forming a part of the seat-carrying frame in a manner for the arm to be received in the groove 24, the extremity of said arm abutting solidly against the shoulder 25. Bolts 26 are passed through the grooved hangershank and the arm of the cutterframe in order to make the hanger fast with the cutter-frame arm in a very substantial and secure manner, and in this connection it is to be observed that the flanges and the shoulder formed on the shank by the provision of the groove 24 therein serve to relieve some of the strain on the connectingbolts 26. The circumferentially-grooved por tion of the hanger-sleeve is received loosely in the axle-bearing 12 in a manner for the shoulders or collars 23 to bear against opposite sides of the axle-box, whereby the hanger is loosely connected to the box in order to turn or rock freely therein, and at the same time the shoulders restrain the hanger-sleeve from endwise displacement in said axle-box. The polygonal part of the axle passes through the polygonal opening of the hanger-sleeve, so that the hanger is made fast with the axle for the purpose of making the axle and hanger turn in the axle-box on the adjustment of the cutter-carrying frame. 1

Any suitable operating means may be employed for the purpose of raising and lowering the cutter-carrying frame on its pivotal connection with the seat-frame without changing the position of the latter. As one means for thus adjusting the cutter-frame I employ a lever 27, which is fulcrumed to the drafttongue by a bolt 27, said lever carrying a latch 28, adapted to engage with a notched segment 28, which is fixed to the drafttongue. The lower end of this lever is shown by Fig. 3 as having a link 29 pivoted thereto, said link being pivoted to one end of an auxiliary lever 30. Said lever 30 is fulcrumed on the rear bar of the seat-frame to have its rear extremity linked to the cutter-frame at the middle thereof; but it is obvious that the axle 13 may be provided with an arm and the lever arranged to be connected with said arm in order that the axle may serve as the means for raising the cutter-carrying frame, because the hangers 18 are made fast with the axle and the frame and are mounted so as to turn in the axle-boxes of the seat-frame.

the present invention resides in a dou'ble winged central cutter 33, which is carried by the middle cutter-hanger 31, and in connec tion with the central cutter 33 I employ two series of reversely inclined single cutterblades 34 35, arranged as shown more clearly by Figs. 1 and 2 of the drawings. struction of the central cutter 33 is represent ed by Fig. 6 as consisting of the blades 36 37, arranged in divergent positions so as to meet in a prow at the front middle part of the cut ter, each wing or blade of the double cutter having a lower cutting edge. The wing or blade 36 of said double cutter is provided with an upwardly-extending moldboard 38; but the other wing or blade 37 has its ends bent to form the flange 35-9, the latter being applied against the inner face of the wing 36 and fas= tened thereto by the bolts 40. The ends of the wings or blades where they meet are beve eled and inclined upwardly and rearwardly to form the cutting edge 41 at the front extremity of the double cutter, and as each wing or blade has a cutting edge it will be seen that the double cutter is adapted to sever the roots of any weeds which may lie in its path, whereby the cutter is adapted to sever a comparatively wide swath and to deflect the weeds or trash inopposite directions from the central line of the machine.

The series of single blades 34, carried by the cutter-hangers on one side of the machine, are arranged in positions oblique to the line of draft and substantially parallel with one blade of the double central cutter; but the other series of single cutter-blades 35 are inclined to the line of draft in reversed relation to the single blades 34, and thus arranged to lie substantially parallel to the other blade of the double central cutter. It is therefore to be understood that the two series of reverselyinclined single cutter-blades are adapted to act on the roots of the weeds and other vegetable growths within the area of the cutterframe, and these single blades are disposed in such relation to the double central cutter as to coact therewith in deflecting the weeds and trash in opposite directions to the line of draft,

whereby the draft of the machine is materially lightened. I also contemplate providing each of the single cutter-blades with an upwardlyextending moldboard 42, and each cutter of the series has the curved fingers 43 arranged .to extend in front of the cutter-hanger forassisting the cutters in deflectin g the weeds and trash to the rear of the cutter mechanism, thereby minimizing the tendency of the operating devices to become clogged by accumulations of refuse.

Changes may be made in the form and proportion of some of the parts while their essential features are retained and the spirit of the invention embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Although I have shown and described two The con series of reversely-inclined single-blade cutters on opposite sides of a double central cutter, I would have it understood that the machine may be equipped with a continuous series of double bladed cutters each constructed in accordance with the double cutter of the type shown by Fig. 6 of the drawings.

Having thus described the invention, what I claim is 1. In a weed-destroyer, the combination with a seat-frame, and acuttercarrying frame, of a Wheeled axle extending across the seat-frame, frame-hangers sleeved on said axle and secured rigidly to the cutter-carrying frame, said hangers being mounted in the seat-frame to turn freely therein.

2. In a Weed-destroyer, the combination with a seat-frame, and a cutter-carrying frame, of a polygonal wheeled axle extending. across the seat-frame, frame-hangers sleeved on said axle and secured rigidly to the cutter-carrying frame,said hangers being mounted in the seat-frame to turn freely therein, and means for adjusting the cutter-carrying frame, substantially as described.

3. In a weed-destroyer, the frame-hanger cast in a single piece and comprising the shank and the sleeve arranged substantially at right angles one to the other, said sleeve having a polygonal axle-opening and the external annular collars, substantially as de scribed.

4. In a Weed-destroyer, a frame-hanger consistin g of the right-angularly-arranged sleeve and shank, said shank provided with a lon gitudina] groove, and the sleeve having an annular groove bounded by the spaced collars, substantially as described.

5. In a weed-destroyer, the combination with a seat-frame,of the axle-boxes,the frame= hangers having grooved sleeves fitted loosely in said boxes, a cutter-carrying frame secured firmly to the hangers, an axle passing through the sleeve of said hangers, and means for adjusting said cutter-frame, substantially as do scribed.

6. In a Weed-destroyer, a double cutter consisting of blades meeting one another and united together at the center of the cutter, the meeting ends of said blades being beveled and inclined to form a sharpened prow, and the blades being formed to diverge rearwardly from a point in the rear of the sharpened front edge of the prow and one of the blades being continued upwardly at its front end to form a colter, and curved fingers attached to the colter with their upper ends extending away from and over the blade of which the colter forms a part.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
