SPECIFICATION forming part of Letters Patent No. 358,453, dated March 1, 1887.

Application filed September 20, 1886. Serial No. 214,040. (No molcl.)

To all whom it may concern.-

Be it known that I, HUFF. JELKS, a citizen of the United States, residing at Oentreville, in the county of \Vilkinson and State of Mississippi, have invented a new and useful Improvement in Cultivators, of which the following is a specification.

My invention relates to an improvement in cultivators; and it consists in the peculiar construotioh and combination of devices,that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a cultivator embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view showing the swinging arms arranged in line with each other and extending obliquely across. the central beam, thereby arranging the plows attached to the laterally-adjustable beams in a single oblique line, the plow-standard being removed from the central beam. Fig. 4 is a similar View showing three cultivating-plows arranged in a single oblique line projecting from opposite sides of the central beam, two pair of the swinging arms and two of the cultivating-plows being removed.

A represents the central beam of the cultivator, which is made of wrought-iron or other suitable material, and has its front end bent verticallyto form a raised oifset, B, and the extreme front end of the beam is bent upwardly, to form an arm or hook, O, for the attachment of the clevis. A series of openings, D, are made in the front end of the beam to permit vertical adjustment of the clevis. An opening, E, is made through the offset B, and through the said opening passes a bolt, F, which secures the front ends of the plow-handles G to the front end of the beam. These handles are spread apart near their rear ends by a transverse rod, H, and from theends of the said rod depend brace-bars I, which have their lower ends bolted on opposite sides of the rear end of the beam A. The said beam has a series of openings, a, near its rear end. The upper end of the said brace-arms are pro Vided with a series of openings, 2', by means of which the rear ends of the plow-handle may be vertically adjusted.

K represents swinging arms, which are pivtheir front and rear ends pivoted between then upper and lower arms K by means of bolts N and N. There are four of these beams M. two being arranged on each side of the beam A.

As shown at Fig. 2, the bolts L, which connect the swinging arms to the central beam, pass through the openings k at the inner ends of the said arms, thereby extending them out wardly to their full extent from the central beam. The inner ends of the swinging arms overlap each other, and thereby spaces are left corresponding to the thickness of the said arms between the lower sides of the beams M and the lower arms K on one side of the central beam, and between the upper sides of the beams M and the upper arms K on the opposite side of the central beam. These spaces are filled by washers P, which are placed on bolts N, as shown at Fig. 1.

From the foregoing description it will be readily understood that the beams M are always maintained parallel with the beam A, and that by moving the arms K toward or from the said beams A the said beams M may be adjusted laterally to any desired distance from the beam A. To the outer ends of the upper front arms K are pivoted slotted arms 0, which extend inwardly to the rear upper arms, and are connected thereto by means of one of the bolts, N. The function of the rods 0 and the bolts N is to secure theswinging arms K at any desired angle with relation to the beam A. m

R represents a series of cultivatingstandards, to the lower ends of which are attached the usual cultivating plows or shovels, S. These standards are bolted to the beam A and to the beams M by means of transverse bolts T, which extend through the upper ends of the said standards and through the said beams.

As shown in solid lines in Fig. 2, the arms K are extended rearwardly and outwardly from the central beam, A, at an angle of about forty-five degrees thereto, thus carrying the cultivators attached to the beam A. When thus arranged, five plows are employed, and plows attached to the outer beams, M, are in rear of those attached to the inner beams. The said plows may be caused to work at any desired distance from the central plow attached to the beam A by adjusting the rear outer ends of the arms K toward or from the central beam; or the arms K may be extended parallel to each other and at right angles to the beam A, so as to place all of the cultivatingteeth in a single transverse line, as shown in dotted lines in Fig. 2.

If it be desired to employ four of the plows, arranged in a single oblique line projecting from opposite sides of the central beam, this may be done by removing the plow from the central beam and removing the bolts L from the openings k of the swinging arms, and removing the bolts N from the central openings, 7:, sufficiently to release the washers P at their joints, and then arranging the swinging arms in line with each other, so as to cause their inner ends to overlap, with their openings k coinciding with the central opening, It, and the openings k coinciding with each other. The bolts N are then inserted in the coincident openings k and k and the bolts L are passed through the coincident openings 76, and the central beam and the swinging arms are then arranged in an oblique position on the central beam, with the swinging arms parallel with each other, as shown at Fig. 3.

If it be desired to employ only three plows arranged in a single oblique line, this may be done by entirely removing two pairs of the swinging arms, two of the beams M and'their plows, and attaching the remaining beams M to the ends of the remaining pairs of swinging arms, bolting the latter to the central beam through the central opening, k, and attaching a plow to the central beam, as shown at Fig. 4..

The function of the opening a, near the rear end of the central beam, is to permit aplowstandard to be attached to the rear end of the central bcam,instead of to the front end thereof, when it is desired to throw out the last furrow of a row.

Having thus described my invention, I claim- 1. The combination, in a cultivator, of the central beam, A, the swinging arms K, having the openings k, k, and k, the beams M, the adjusting-arms 0, connecting the swinging arms K together, and the bolts N, N, and L, to connect the inner ends of the swinging arms to the central beam and to each other, so that they overlap, and to connect the beams M to the swinging arms, substantially in the manner and for the purpose described.

2. In a cultivator, the combination of the central beam, the arms K, pivotally bolted to the upper and lower sides of the said beam and having central and end perforations adapted for double sets of plows, the beams M, parallel with the central beam and having their front and rear ends pivotally bolted between the pairs of arms K, the adjusting-braces O, and the washers P, interposed between the ends of the said beams and the arms, substantially as described.

3. The central beam, A, in combination with the arms K, pivoted thereto and arranged on each side of the beam, the beams M, pivotally connected to the outer ends of the arms K, and the arms O,adj ustably connecting the arms K together on opposite sides of the beam A, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
