CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 250,876, dated December 13, 1881,

Applicationfiled June 24, 1881. (No model.)

To all whom it may concern Be it known that I, JAMES BRADY, residing at Dixon, in the county of Lee and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Ouitivators, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is alongitudinal vertical section on line so a; of Fig. 2. Fig. 2 is a rear view with the plows removed, and partly in section; Fig. 3, a section showing the manner of forming the front end of the plow-beams and of adjusting them laterally, and Fig. 4 an elevation of the axle-frame detached.

The object of this invention is to improve the means for adjusting the front ends of the plowbeams so as to increase or diminish the space between the plows of the two beams.

My invention consists in a novel construc- 'tion and combination of parts, which will be fully hereinafter described in detail, and specifically pointed out in the claims.

In the drawings, A A indicate the arch or axle-frame; B, the wheels; B, wheel-spindles; O, the tongue; D, braces; E, plow-beams; F, handle; G, plows; H, braces; I, rocking plate; a, the adjusting block or cap for the upper end of the plate I; b, the adjusting set-screw; c, bearin g in block a for the upper endof plate I (1, holes in plate I for vertically adjusting the front ends of the plow-beams; and 0, holes in the parts A for laterally adjusting the lower end of plate I, and thereby narrowing or spreading the front ends of the plow-beams.

Theplow-beams, with their handles and plows or shovels, and the wheels, tongue, and braces D, with their rearward extensions and the hangup devices f g, are, or may be, made in any of the usual or well-known forms.

The arch or axle-frame A is made of a single piece or bar of iron bent or formed into the shape shown at Fig. 4, and itslower ends, A, are turned inward, as shown, to form supports for the rocking plates I and attaching parts for the braces H. The wheel-spindles 'B are permanently attached thereto, and may be made a part thereof, or they may be adjustably attached.

The arms A of the arch are provided with holes 6, adapted to receive the lower ends of the plates I, and the braces H are attached to their inner ends by rivets, bolts, or clips, and said braces are inclined inward and forward, as shbwn, and are attached at their upper ends to the braces D. The plates or bars I are flattened above their lower pivots, and are provided with holes d, for the vertical adjustment of the front ends of the plow-beams, which are madeto fork the plate. The plates I are extended upward to the top of the arch, and are pivoted in the bearing 0 of the block a. The blocks a, are cut away at the bottom, so as to be easily applied, and they are held in place by the set-screws b, by means ofwhich they may be adjusted along the top of the arch, as desired, and as the bearings 0 are in front of the arch, there is no strain on the blocks or their set-screws and as it is not essential that the plates I should be exactly vertical, a close or fine adjustment can be made, notwithstanding the lower adjustment by holes.

By making the arch or axle-frame in the form shown it passes around outside of the beams and lower ends of the braces and under the beams, and the sides are brought close to the wheels, so that the weight of the parts comes on the wheels without leverage, and any bondingor straining on the parts A does not affect therunningof the wheels Ialso avoidjoints by this construction, and thereforemake a stronger frame, and by connecting the braces 1-1 with the inner ends of the frame I give them a strong support, and the braces form guides to direct the growing'corn through the open space, and prevent the leaves from catching on the frame.

I do not claim, broadly, the method shown for attachingthe plow-beams at theirfrontends.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the arch or frame A, having inwardly-projecting portions A, of the adjustable blocks a, arranged to slide horizontally on the arch or frame, and provided with the bearings c, and the upright plates I, having their upper ends arranged in the hearings on the sliding blocks and their lower ends adjustably connected with the inwardly-projecting portions of the arch or frame, substantially as and for the purpose described.

3. The combination of the arch or frame A, constructed as described, with the braces H and D, tongue 0, pivoted plates I, and laterally-adjustable blocks a, provided with bear- 15 ings c, in which the upper ends of the plates are arranged, substantially as set forth.
