WILLIAM R. BURBRIDGE, OF DANBURY, NEBRASKA.

WEED-CUTTING CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 484,405, dated October 18, 1892.

Application filed July 30, 1892. Serial No. 441,728. (No model.)

To all whom it may concern.-

Be it known that I,W1LLIAM R. BURBRIDGE, a citizen of the United States, residing at Danbury, in the county of Red Willow and State of Nebraska, have invented certain new and useful Improvements in Weed-Cutting Cultivators; and I do declare the following to be a full, clear, and exact description of the nvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in cultivators; and it has for its object to improve upon the construction and render more efficient in operation that class of cultivators in which provision is had for cutting weeds and at the same time cultivating or harrowing the soil.

The invention has for a further object to provide a machine of the character mentioned in which the use of wheels will be entirely dispensed with and in which by reason of the peculiar form of the cutting-blades and the novel construction, arrangement, and adaptation of the various parts of the machine a light and at the same time strong and durable machine is provided, which will serve to thoroughly cultivate the soil between the rows, and at the same time will effectually cut all weeds or stocks which may grow within the path of the machine.

An essential feature of the invention resides in the novel form of the weed-cutting blades,which will be hereinafter fully defined.

The invention is fully illustrated in the accompanying drawings, which, with theletters of reference marked thereon, form a part of this specification, and in which drawings'- Figure 1 is a perspective view of a machine constructed in accordance with my invention. Fig. 2 is amodified form. Fig. Sis an enlarged detail in perspective of one of the undulating knives or blades. Fig. 4 is a detail of a detached blade.

Reference now being had to the details of the drawings by letter, A designates the machine, which consists of the runners B B,which at their forward ends are extended upward and curved inwardly to form the arch O, to which is securely bolted or otherwise suit.- ably secured the forward end of the board seat D, which seat is similarly supported at a point adjacent to its rear end by an arch E, which rises from the runners B near their rear ends, as shown.

G G are laterally-extended horizontal arms, which are attached at their inner ends to the runners 13 near their forward ends. These arms serve as foot-rests for the driver, and to them is secured the curved rod H, to which the team may be attached in the usual manner.

I Iare outwardly-curved undulating blades, which are bolted .at their forward ends securely, either to the rear ends of the runners, as shown in Fig. 2 of the drawings, or to the lower ends of the uprights which form the rear seat-supporting arch, as shown in Fig. 1.

As the peculiar form of the blades I is of great importance, I have shown one of these blades in detail and upon an enlarged scale in Fig. 3 of the drawings, and upon reference to said figure it will be observed that the outer or cutting edge of the blade is inclined slightly downward, and that the blade is undulating in the direction of its length, the blade being curved slightly downward near its point of attachment to the machine and again curved upward at the point K, while the extreme outer end of the blade is again curved downward. By this construction efficient work is assured, as the driver is enabled to readily regulate the depth of cut of the blades by simply shifting his weight forward or backward upon the seat, as will be readily understood.

The blades I are provided at points near their forward ends with short and substantial auxiliary cultivating-blades L. These blades .are bolted securely to the blades I and are extended downward and inclined rearwardly, as shown, and, as will be observed from their form and position, they will serve to thoroughly cultivate the ground through which they are passed.

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

The herein-described Weed-cutter and cul- 5 tivator combined, the same comprising the runners, the seat-supporting arches rising:

therefrom, the seat, the foot-rests G, the'undnlating weedcutting blades I, attached at the rear'ot the machine, as described, and the
