WEED-CUTTER.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed anuary 30, 1996. Serial No. 298.657.

To all whom it may concern.-

Be it known that I, JOHN T. SHORT, a citizen of the United States, residing at Rossville, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in l/Veed-Cutters, of which the following is a specification.

This invention relates to agricultural implements in general, and more particularly to an improved form of weed-cutter.

The weed-cutter as constructed by me comprises, essentially, a framework having two horizontally-rotating cutters mounted therein, said cutters being located abreast of each other and being adapted to be adjusted vertically independent of each other.

The object of the invention is to so design the weed-cutter that it can be cheaply con structed out of the ordinary forms of structural metal and so that it will be effective and durable in operation.

For a full description of the invention and.

the merits thereof and also ,to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspectiveview of the weedcutter. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation. Fig. 4 is a detail perspective view of one of the rearwardlyextending frames, and Fig. 5 is a similar view of one of the plates employed in connecting the cultivating-shovels to the frames.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In its simple'form the invention comprises, essentially, an axle mounted upon wheels and having a pair of rearwardly-extending frames pivotally connected thereto, said frames being adapted to be moved up and down inclependently of each other and being each provided with rotary cutters.

The numeral 1 designates the axle, which is bent upwardly and arched at an intermediate point, as seen at 2. A beam 3 is connected to the top of the arch 2 and is held in a rigid position with relation thereto by means of the forwardly-extending oblique braces 4, which connect the beam to the axle 1 and are secured to the latter adjacent to the vertical portions of the arch. A wheel 5 of any conventional construction is mounted upon each end of the axle 1, and each of the wheels is provided on its inner face with a sprocket 6, which is shown as held in place by means of the hook-bolts 7, which engage with the spokes. A rearwardly-extending frame 8 is pivotally connected to the axle, at each end thereof, and for this purpose bearings 9 are provided, which are formed in two sections fitting around the axle between the wheel and the oblique braces 4 and held to gether by means of a bolt or other suitable fastening means. Each of these bearings 9 is formed with a block or extension 10, to which the frame 8 is secured.

In the preferred form of the invention, as shown in the drawings, the frames 8 are formed of a single strip of bar metal, which is bent so as to have .an approximately rectangular shape and has its ends secured to opposite sides of the blocks 10, projecting from the bearings 9. However, the essential feature of the frames resides in the two spaced side pieces, between which the rotary cutters 11 are mounted, and the particular shape of the frames is immaterial. It will be observed that the outer side pieces of each of the frames extend directly back from the block 10, while the inner side pieces project inwardly toward each other. The horizontal rotating cutters 11 are mounted upon blocks '12, secured to the lower edges of the side pieces of the frame. In order to enable the blocks 12 to be readily secured in position, the side pieces of the frames8 are formed of two spaced strips of metal, which are separated by means of strips of wood 13. In securing the blocks 12 to the side pieces bolts 14 are employed, which pass through the blocks and the wooden strips 13 in the sides of the frames. The lower faces of the blocks are preferably protected by means of metal plates 15, and similar plates 16 are placed upon the upper portion of the side pieces.

The hub 17 of each of the cutters 11 is provided with a series of radial arms 18, which have their extremities bent slightly forward and connected to the cutting-blades 19. It will be observed that these cutting-blades 19 are bent longitudinally to a slight extent, so that the edges thereof have a sliding contact with the weeds, and the effectiveness of the cutter is thereby greatly increased. The axles 20 upon each of the hubs 17 are 1nounted to project outwardly through the outside block 12 on each of the frames 8 and are provided with sprockets 21, which are preferably smaller than the sprockets 6. These two sprockets on each side of the machine are connected by means of a chain 22,- andthe sprockets preferably bear such a relation to each other that the cutters will make-three revolutions for every revolution of the wheels, although this is immaterial and maybe changed to suit the requirements of various conditions. It will thus be seen that when the machine is drawn over the field the motion of the wheels 5 is transmitted to the cutters 11v through the chains 22.

In order to provide for the vertical adjustment of the frames 8, a lever 23 of the bellcrank type is pivoted upon each side of the beam 3, and one arm of each of the levers is connected by means of a link 24 to the corresponding frame 8. When thus adjusted,

\ each of the frames 8 can be movedup or down by operating the corresponding lever 23, and this movement of each ofthe frames is inde endent of the opposite frame. Racks 25 are coated upon the beam 3, so as to engage with the levers 23 and lock them in the desired position. A cultivating tooth or shovel 26 is connected to each of the frames 8, and the shank bearing the shovel is provided with a series of openings which admit of its vertical adjustment with respect to the frame. These shovels are preferably secured to the inner sides of each of the frames near the forward end thereof, and for this purpose lates 27 are provided. These plates 27 are formed with four flanges, the upper and lower flanges being bent so as to embrace the top and bottom of the side pieces of the frame and prevent-any rotary movement of the plates, while the s ide flanges are bent outward and engage with the shank 28, to which the cultivating-shovel 26 is attached to prevent the same from turning. It will be observed that the same bolt by means of which the link 24 is secured to frame is employed in I connecting the shank 28 thereto, and this feature tends to simplify the construction, and thereby increase the durability of the machine.

In order to prevent any horizontal move- I ment of the frames 8, brace members 29 are provided, which connect the inner corner of each of the frames to the axle 1, the ends of the braces in engagement with theaxle being looped to form an eye, and preferably fitting against the lower end of the oblique braces 4.

The machine is intended to be attached to a cultivator by means of the beam 3, and

when so connected it will be readily understood that both of the cutters can be lifted sition when desired. Another advantageous feature resides in the fact that the machine may be employed with equal facility either upon planted or listed corn.
