IMPROVEMENT m CULTIVATORS.

Specificationforining part of Letters Patent No. 174,320, datedFebruary 29, 1876 application filed r December 4, 1875. i

ments in Cultivators or Corn-Flows, of which the following is a description, reference being- I had to the accompanying drawings:.

My invention consists, first, of the arrangement and combination of parts whereby the arch of a corn plow or cultivator is supported independently by each plow; second, the construction and arrangement of partswhereby the plow-shovels can be adjusted to-any desired depth in the ground; third, in the construction and arrangement of the draw-bars whereby the spindles of the wheels are in front and below the arched axle.

Figure 1 represents a side elevation of my improved cultivator. Fig. 2 is a plan view of the same, showing the arrangement of parts more fully. Fig. 3 is an enlarged plan view of the connections of the plow-beams with the independent arch-supporting boxes. Fig. 4 is a side view of Fig. 3, showing the arrangement of parts for the adjustment of the plow-shovels in the ground. Fig. 5 represents a front and side view of the adjustable sled-runner or plowpoint support. Fig. 6 is a sectional view of the independent arch-supporting boxes, showing the arrangement of the collar and top and bottom studs, that operate in slots formed in the top and bottom halves of the supportingboxes. Fig. 7 shows the collar on the arched axle. Fig. 8 represents a top view of the drawbar and wheel-spindle. Fig. 9 is an end view of Fig. 8. Fig. 10 shows two side views of Fig. 8. Fig. 1.1 represents the manner of attaching the sled-runners or plow-point supports and fender to the plow-beams. Fig. 12 is a side view of the fender andclamp.

A A represent the wheels of the cultivator, which are mounted on the spindles B that are secured to the projection B of the drawbar 0. (Shown more fully in Figs. 8, 9, and 10.) hook, D, at the front end. The other end is provided with two projecting flanges, (3 G which form jaws, that fit overand under the flanged end pieces B of the arched axle B B and is pivoted thereto by the bolt 0 Theend piece B has flanges 0 0 above and below,

The draw-bar G is also formed with a so as to present a wide bearing on the inside of the jaws Q 0 and the end of the arched shaft or axleis inserted in the piece B and secured therein by the pin 00. (Shown in Fig. 3.)

In Figs. 1, 2, and s it will be seen that the spindle B is located below and in front of the arched axle B B and is free to move in any direction on the pivot-bolt O, as indicated by :the dotted lines y y, Fig. 2, and allow the wheel A to follow the horse independent of the other wheel, with the draft below the arched axle BB which will allow the wheels to pass over obstacles with little or no strain on the arched axle.

On the arched axle B B between the arch B and end pieces B are secured the collars m, Fig. 7, with a stud, 'w above, and 10 below, Fig. 6. Over and under these collars w 10 and encircling the shaft'B, are the inde pendent arch-supporting boxes R E, Figs. 2,

.3, and 6. Each of these boxes are perforated with a slot, to, above and below, through each of which the studs w and 242 project, the design of which is to support the arch in a perpendicular position, and prevent it from turning down either in-front or rear.

The two halves of the independent arch-supporting boxes R R are securedtogether bybolts h h in the lugs g g in-front, and by the bolts 01 at the rear. to. the attachments M N on the end of the plow-beams, so as to allow the plows P to be moved laterally either way, as indicated by the dotted lines ff, Fig. 2.

The plow beams are curved downward at their rear ends, and are provided with shovels P, attached in the ordinary manner. The front ends of the beams E E are securely bolted to the sides of the gib-slide S. (Shown more fully in Figs. 3 and 4.) The front end of the piece S is formed with a gib, S, that fits on both sides of the upright slide N, and is secured at any desired height by the bolt 10 passing through the slot N, which will allow the plows'to be adjusted to any desired depth. At the rear of the slide N, and cast on the top and bottom of the gib-piece S, are lugs or brace-guides T, that help support the beams against the slide N. On the front side of the slide N is cast the pivoted connection M, that The bolt 01 acts as a pivot i is pivoted tothe independentrarch suppotting boxe's RRtbyithe pivot-bolt d; before described.

The two plow-beams E E, on each side of the arch B are formed with the inner beam shorter than the outside beam, and the handle F is secured by the.bolt .J and brace-Gr, as. shown in Fi'gSILandZ. "GW'theinsideOfthe short beams E, and attached thereto by the bolt J, is the washer V,' with:theesled-ru nner or plow-shovel-supporting arm K, pivoted-on the bolt, between the washer V and the fend er-clamp U. (Shown more fully in .Fi g. ,11.)
