EDWIN M. LAMBSON, OF W'ALLA VVALLA, VVA'SHINGTON.

WEED CUTTER.

SPECIFICATION forming part of Letters Patent No. 794,361, dated J ul y 11, 1905.

Application filed June 14,1904. Serial No. 207,145.

To (LZZ 1071 0777, it may concern:

Be it known that I, EDWIN M. LAMBsoN, a citizen of the United States, residing atWalla WValla, in the county of Wallawalla and State of Washington, have invented certain new and useful Improvements in Weed-Cutters; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved weed-cutter for clearing fields of weeds prior to seeding; and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of one section of my improved weed-cutting machine. Fig. 2 is a similar view showing the sections connected together. Fig. 3 is a side elevation. Fig. 4 is a detail view of one of the cutters. Fig. 5 is a detail sectional view.

My improved weed-cutting machine consists of a plurality of sections, here shown as three in number, the inner section being designated as 1 and the outer sections as 2. Each section has a frame 3. The side beams 4 and center beam 5 of each frame are each composed of a pair of metallic bars or strips 6, spaced apart, as shown, by means of spacerblocks 7 at their front ends and at or near their centers.

Runners 8 have their front and rear ends upturned to form standards 9, which are placed between the spaced bars of the beams and are provided with adjusting-openings 10. Bolts 11 12, respectively, secure the front and rear standards of the runners to the beams, and the openings 10, with which said standards are provided, coact with the said bolts to adapt the runners to be vertically adjusted with reference to the frame, as will be understood.

A cross-bar 13 connects the front ends of the beams of each frame. Its ends are downturned and secured to the outer sides of .the outer beams by bolts 14:. Its center is secured on the center beam by an eyebolt 15, the eye of which is between the bars of which the center beam is composed and is engaged by a bolt 16.

Between the center and side beams of each frame are braces 17, each of which comprises members 18 19 20. The members 18 are obliquely disposed and have their front ends secured to the center and side beams by the

bolts

14 and 16. Said members 18 converge rearwardly, and between the rear ends of each of them is a spacer-block 21. The members 19 are bent to form forwardly and rearwardly extending arms 22 23, respectively, at their outer and inner ends. Said arms 22 are bolted to the inner and outer beams, and the arms 23 of said members are bolted to the rear ends of the members 18 by the bolts 2t, that also secure the spacer-blocks 21 in place. The rear members are disposed obliquely,

as shown, have forwardly-extending arms 25 at their inner ends, which bear on the arms 23 of the members 19, and have arms 26 at their outer ends, which bear against the inner and outer beams at the rear ends thereof.

In connection with each section I employ cutters, here shown as five in number, disposed in two rows, one in advance of the other. Each cutter 27 comprises a standard 28, having a forwardly-extending arm 29 at its upper end and a foot 30 at its lower end. The foot has oppositely-inclined upwardlyconverging sides 31, which extend forwardly and converge to a point 32. Under the foot and secured thereto is a cutter-plate 33,

which is V- shaped and the rearwardly -diverging arms 34 of which extend rearwardly from the foot.

The cutters of the front row, carried by the outer frames 2, and the cutters of the rear row, carried by the center frame 1, have their arms secured between the arms 23 of the brace members 1.9 by the bolts 35, which secure said arms to the arms 25 of the rear brace members 20. The other cutters have their arms secured between the members of the center and side beams by bolts, as shown. Hence the cutters of the front row are disposed in the spaces between those of the rear row, and the width of the cutter-plates is such that they are disposed in overlapping relation, so as to out all of the Weeds standing in a space equal to the width of the machine. The side or outer beams of the inner section 1 are shorter than those of the outer sections to preserve the proper overlapping relation of the cutters in the rows entirely across the machine.

The sections are respectively secured by links or other suitable connections 36 to the sections 37 of a draft-tree 38, the sections of which are pivotally connected or hinged together, as at 39.

When the machine is in operation, the runners run upon the surface of the ground, and the plates of the cutters operate at a slight depth below the surface of the ground and serve to cut the weeds at their roots, so as to effectually destroy the same. By vertically adjusting the runners by the means hereinbefore described the plates of the cutters may be caused to operate at any required distance below the surface.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A weed-cutting machine having a frame provided with longitudinal beams each comprising sections which are spaced apart, runners having standards secured between the spaced sections of the beams and vertically adjustable with reference thereto, said runners being of such length as to serve to maintain the frame in a horizontal position, and cutters in rear of said runners and in line therewith, each of said cutters comprising a standard having its upper end provided with an integral forwardly-extending arm secured between the sections of one of the beams, said standard being provided with a foot at its lower end provided with oppositely-inclined upwardly-converging sides which extend forwardly and converge to a point, and a V- shaped cutter-blade having its apex portion secured under the foot, said blade having rearwardly-diverging flat arms which extend rearwardly from the foot and lie in a common horizontal plane.

2. A weed-cutting machine having a frame provided with a beam and a weed-cutter, the latter comprising a standard having its upper end secured to the frame and a foot at its lower end having oppositely inclined upwardly-converging sides which extend forwardly and converge to a point, and a V- shaped cutter-blade having its apex portion secured under the foot, said blade having rearwardly-diverging flat arms which extend rearwardly from the foot and lie in a common horizontal plane, the point of the foot extending forwardly in advance of the apex portion of the cutter-blade.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

EDWIN M. LAMBSON.
