IMPROVEMENT IN CULTIVATORS.

Specification forming art of Letters Patent Nb; 115,459, dated May 30, 1871.

j I, CONRAD FURs'r,of the city of Chicago, in the county of, Cook and State of Illinois,

have invented certainnew and useful Improvements in Cultivators, of which the following is a full description, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 is a perspective view; Fig. 2, a

top view of the frame; and Fig. 3, a longitudinal vertical section on line a; y of Fig. 2.

y The nature ofmy invention consists in making the draft-rods, to which the plow-beams are attached, adjustable; in so constructing construction and operation of the same.

In the. drawing,,A represents the curved and bent frame; B, the tongue; 0, the axles; D, the wheels; E, F, and G, beams, plows, and handles of ordinary construction; H, the double-tree; I, the whiffletrees; J, bent rods or draw-bars; K, clips for securing the frame to the axles; a, screw-nuts for adjusting theupper ends of the rods J ;j b, stops or shoulders; 0, clips or clamps for adjusting and securing thelower ends of therods J; 0, braces;

f, a bent bar or clevis for attachinga double tree. The frame A is constructed from a single piece of wrought-iron and bent in the formshown. By making it of this form it answersall the purposes of a bent axle, and does not require bracing. This frame is secured to the short axles G by clips K, and the ends of the frame" project behind such short axles. Thewheels D are made in the usual form. The tongue B is made a of two pieces brought together at the front; ends and separated at the rear, as shown at Fig.1. The whiffletree and double-tree]; H are made and attached in any ordinary manner. The rods J J are adjustable, and the beams E are attached to them. The ends of these rods are bent, and

these bent ends are fastened-to the frame A, both at their upper and lowerends, by means of clips or eyebolts a andnuts, or in any other suitable manner. At their upper. ends the bolt used to i connect the frame and tongue- J in place. The bent ends of the bars J, to which the beams E-are attached, are made longer than the other ends, making the space between the frame A and bars J greater at the lower than at the upper ends, to furnish a place for the attachment of the beams. At

their upper ends these bars J are provided with a nut, a. By this nut the space between the bars J can be adjusted at'any required distance. To the upper and lower sides of the front ends of the beams E plates k are fastened. These plates extend beyond the ends of the beams a sufficient distance to allow of the insertion of a small wheel, d,be-

tween them, leaving space enough between the endof the beam and this wheel to allow the lower end of the bars J to pass through and fasten the beams to the ends of theframe. The ends of the beams should be chamfered off, or the plates bent down, so as to fit the hitchingrods J and prevent the rocking of y 'the beams. This wheel (1 is placed between the plates 70 to allow an easy lateral movement of the beams E upon the bars J. It is important that the beams should not rock, as it is desirable to run close to the plants, and this cannot be done with safety unless the plows are held in their vertical position. The stops or shoulders b are made apart of or permanently attached to the rods J, so that, when the space between the beams is adjusted, the space between the rods is also adjusted, as adjusting the space between the hitching-rods adjusts the beams. This is easily done by loosening the eyebolts c and placing the hitching-rods J in position, and then tightening said bolts. The upper end may be adjusted to the screw-nut a. g are bent rods, attachedto both sides of the split tongue B at the rear end to receive thehooks h fastened in the beams E to hold the beams and shovels clear from the ground when the cultivator is moved from place to place. j are hooks made to slide on so that, when the plows are moved laterally, they shall not be lifted out of the ground. The chains '0 are fastened to the beams E by a staple, and

in this way the pitch of the beams can be ad-' justed.

Cultivators have heretofore been made with the beams so attached to the bars or frame as to be adjustable; but the bars were immovable, and always remained at the same distance apart; and in cultivating large corn the inner ends of these bars are likely to strike the stalks and break them, causing considerable damage; but by making the bars J adjustable this objection is wholly obviated, the bars being movable with the beams.

In the drawing, the bars J and beams E are shown in position for cultivating large corn; but for cultivating small corn the distance between the beams should be less than that shown, which is readily accomplished by brin 5; ing the bars J nearer together. I

What I claim as new is 1. The frame A, constructed as described, and extending back of the axles, when so combined with the short axles (J that the ends of the plow-beams may be raised and lowered, substantially as and for the purposes specified.

2. The adjustable bars J, when combined with the frame and plow-beams so as to move with the beams E, substantially as described.
