SPECIIFICATION forming part of Letters Patent No. 274,070, dated March 13, 1883.

Application filed October 31, 1882. (No model.)

To all whom it may concern Be it known that I', WILLIAM S. Wma, a citizen of the United States, residing at Monmouth, inthe county of Warren and State of Illinois, have invented certain new and useful Improvementsin Gultivators; and I do hereby 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, reference being had to the accompanying drawings, and to letters or `figures of reference marked thereon, which form a part of this specification.

- `my invention, Figure 1 is aperspective.

rlhis invention relates to that class of parallel or tongueless77 cultivators in which two or more arches, that constitute the central part of secured with greater strength, and whereby the` arches oreentral parts ot' the axle may be journaled thereto in such manner as to permit of extended lateral adjustment of the gangs of plows; second, in improvements in hinging the arches to the side" frames, whereby the movement of either wheel forward relatively to the other is limited, to prevent such near approach of the side frames to each other as that the axle and wheels may fall over to either side. i

The invention further relates to improvements in the manner of coupling the plowgangs to the side frames, and to other combinations and features of construction, as hereinat'ter described.

In the accompanying drawings, which illustrate a tongueless cultivator as improved by Fig. 2 is a top plan. rFig.3 is an enlarged sectional elevation in a plane indicated by the line c: a: lin Fig. 2. Fig. 4 is an enlarged top plan of one of the side frames and the adjacent ends of thearches. Fig. 5 is an enlarged sectional elevation of an arch-bearing and adjacent parts,

i in line y yin Fig. 2.

Referring to the drawings by letters, the

` same letter indicating the same part in the different igures, letters A represent the side frames, each formed of parallel bars a a', converging at theirforward ends to form a drafthook, a, and connected at their main portions by transverse bars a".v bars-a are connected by and support a spindle, b, and also a bar, b', in front of, parallel with, and in a` plane lower than the spindlezb.

The rear ends of the G C are the supporting-wheels, journaled on `A, by means `of their journals d passing through the holes c in the blocks E, where` they are retained by keys c, as shown. The extent of oscillatory movement of each journal d" in its bearing is limited by means of the shoulders cl coming in contact with the side walls of the groove e', in which said shoulders are located. This arrangement of the arches and side frames and journaled connection between them will permit of advancing either side frame and its adjacent wheelwhile the parallelism of 'the side frames and wheels are preserved by the two arches, as shown by dotted lines at Fig. 2. The grooves c are somewhat wider than the shoulders: d" are thick, and thereby permit ot' oscillation of the journals d" in the holes e to a limited extent, as shown at Fig. 4, but not sutliciently to allow the side frames, A, to come together or so nearly together in turning the cul tivator around in operation, as that it will not sustain itself against falling over sidewise. More than two arches D may be used, but I prefer two as sufficient to retain the wheels in parallel planes when either is advanced for turning the cultivator, or for other purposes.

F F are ordinary gangs of plows, with beams f, handles f', and plows f" of any ordinary g', projecting similarly from its under side and held by the same bolts, g, which hold the plateg. l i

A plate, h, with a groove in its lower side, rests on the spindle b, and has a series of holes, h, either of which may receive a stud,

l 9', which projects from the lower side of the rangement of the spindles b with reference to the arches D is such that the plow-gangs may be adjusted laterally and fixed at points inside ofor outside ot the vertical parts ot' said arches,

as desired. The extended end of the plate g rests beneath and about in contact with the bar b when the plows are in operation, and hence said bar b will come in contact with the plate g and prevent the arches D falling forward when not sustained in upright position by the draft ofthe animals on the hooks at.

The stub-axles c are somewhat in rear of the centers of the frames A, so that the tendency of the arches D is to tilt forward; but should they by any means be thrown rearward they.

will be caught by the plow-beams.

What I claim as new is- 1. In combination with the side frames composed of bars a a', connected by transverse bars a, the arches I), jonrnaled to blocks on the bars a, substantially as and for the purpose speciticd.

2. In combination with the side frames with arches hinged or journaled thereto, and the plow-gan gs, the bar b, to which the plow-gangs are hinged, arranged, substantially as described, with vrelation to the arches to permit adjusting the plow-gangs laterally at points between and also exterior to the vertical parts of the arches, substantially as and for the purpose speciied.

3. In a cultivator, in combination wit-hv side frames and two or more arches hinged or journaled thereto, stops adapted to limit the extent ot' movement of said hinge-connection, substantially as and for the purpose specified.

4. In a cultivator, in combination with side frames provided with blocks E, havingholes e and grooves e', the arches D, having` journals and shoulders on vtheir vertical sides, which shoulders are adapted to coact with said grooves e to limit the oscillating movements of the journals within said holes e, substantially as and for the purpose specilied.

5. In combination with the wheeled side frames having each a bar or spindle, b., and bar b at its rear end, the plow-gangs having plates g g', hinged to the spindle b, and the lower one projected forward beneath the bar b for the purpose of sustaining the arches, substantially as and for the purpose specified.
