CULTIVATOR.

'lECIFCAIION forming part of Letters Patent N0. 334,641, dated January 19, 1886.

Application filed September 9, 1885. Serial No, 176,602. (No model.)

T0 aZZ whom it may concern:

Be it known that I, EDWIN CHILDREN, of Dunleith, in the county of Jo Daviess and State of Illinois, have invented a new and useful lmprovement in Cultivators; and l do hereby declare that the following is a full and exact description of thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to that class of farming implements known as sulky-cnltivators,77 and embodies improvements upon the implement described and shown in Patent No. 159,500, granted to me February 9, 187 5,which is for a shifting contrivance l'or varying the line of a pivoted draft-pole and the plow beams.

The present -improvements relate more particularly to means for raising, lowering, and adjusting the plow-beams to the lever for shifting and varying the line of the draft-pole andA plow-beams, and to a friction-roller on the rear end of the draft-pole; and the novelty consists in the construction, arrangement, and .combination of these and other parts of the machine, all as more fully hereinafter described, and pointed out in the claims.

For a better understanding of the parts in detail, attention is invited to the accompanying drawings, in which- Figure l represents a perspective view taken from the rear of my improved cultivator; Fig. 2, a top plan view of the same; Figs. 3 and 4, details of certain parts. Fig. 5 is a detail showing the connection of the plow-beams and swing-arms to the sway-beam, and Fig. 6 a detail of the shifting-lever and its fulcrum.

Like letters refer to corresponding parts in the several views.

A denotes a rectangular frame mounted upon two wheels, B B, and composed of two front and rear pairs of horizontal cross-bars, a a and a ob, respectively, secured at their ends to the two intermediate side bars, b b, which run parallel at right angles to the former, andare connected at the rear ends to another cross-bar, c.

Gis the draft-pole, pivoted centrally between the front pair of cross-bars, a a, of the frame A, as shown at c, and provided on its rear end with a friction-roller, c, which travels between the rear pair of cross-bars a ce', and renders it easier to shift or change the line of draft.

I) is the drivel-s seat, supported in the rear of the frame A by a single curved spring, or two stout springs, d d, secured at the front ends to th'rear pair of cross-bars a a.

E E are the plow-beams, pivoted at the front ends to a sway-beam, E, which is pivot-ally supported by the parallel swing-arms F F, pivotally connected at their rear ends to the cross-bar c of the frame A, and extendedin front of the sway-beam E far enough to bring the rollers e e upon the front ends to a bearing upon the lower one of the front pair of crossbars, a a. rear end with a rigid arm, e', and a link, f, connects this arm to one of the swing-arms F, and another link, f connects this arm e to an arm, g', of the lever-pin g, so that the motion of said draft-pole, imparted by the lever G, is communicated to the swing-arnis and to both plow-beams, as in my other patent, eX- cept by a few additions and a change in the arrangement of the lever G, the shifting of these parts is rendered more convenient and easier in this machine.

The pin g, to which the lever G is attached, has loose bearings in a bracket, h, secured to the rear cross-bar c of the frame A, and is cast or otherwise provided on its upper end with a ring, g2, having on its inner circumference two recesses, i t', each adapted to receive the pin i at the inner forked end of the lever G. This lever is made telescopic, having an inner handle, G', whereby the driver can transform the machine into a walking-cultivator, and extend this lever to such a length that, when walking,he can operate the same to change the line of draft as conveniently as when riding, and by means of the two recesses rl i in the ring on the upper end of the leverpin g the point at which the lever is attached can be changed by merely disengaging its pin z" from one of said recesses and engaging it with the other, so that a change in the length of the lever-arm shall not affect the power necessary to move the lever.

Upon each of the plow-beams is secured a ratchet-frame, H, in the form of asegment,with which engages a pawl, k, of a lever, H,pivoted to the side of its ratchet-frame. Each lever H has a hooked arm, k', to which is attached one end of a chain, k2, the other end passing down under a pulley, 7a3, mounted on the plow- The draft-pole C is provided at'its' IOO bea1ns,and up to the end of a crane, I, where it is attached io a hook on the saine. Each crane is suspended over the cross-bar c by engagement with a casting or socket, I', pivoted one to each swingarm F, and said cranes are adapted, as shown, to be readily disengaged from their supports. Each casting or socket I has bearing upon an elastic support, m, which may be either a leaf, spiral, or rubber spring; but preferably a metal leaf-spring secured to the swingarms, whereby an elastic or springy motion is given to the plow-beams, and considerable aid is furnished in the raising of the same by thc pawl-and-ratchet contrivances.

By pivotally attaching the plow-beams and the cranes to the movable portion of the frame the lateral movement of the same is much easier accomplished, Yl`or all that the operator has to do is to raise the beams a trilie, and then by the use of the lever shift the draft-pole, and the same movement is transmitted to the plow-beams and their attach 1nents,whereas in other cullivators,where the beams are rigidly attached to the frame, a much greater power is required to shift them laterally.

Having thus described my invention and enumerated some ol" its advantages, what I claim, and desi re to secure by Letters Patent, 1s

l. The combination, in a cultivator, of a movable frame comprising asway-beani and a pair of swing-arms pivotcd at one end and provided with friction-rollers on the opposite end, apair of vertically-adjustable plow-beams pivoted to said swaybeam, a pivoted draftpoleI with a friction-roller on its rcar end, a telescopic shifting lever, and intermediate link connections between said draftpole, swing-arms, and shifting-lever, substantially as and for the purposes set forth.

2. In a cultivator, the combination,with the movable frame comprising; the swing-arms F F and sway-beam E, of the pivoted plow-beams E, ratchet-frames H, secured upon the same, levers H', with pawl k, and arm k', cranes I, andthe intermediate connections with said lcvers, and sockets I', pivoted to the swing-arms F and clastically supported upon the saine, substantially as described.

3. In a cultivator, the combination,with the movable frame comprising a sway-beam, E', and a pair of swingarms, F F, ofthe pivotcd draft-pole C, having arm c, linksf and f, lever-pin f/, having arm g and recessed ring g2, and telescopic lever G, substantially as and for the purposes set forth.

In testimony whereof Ia'llx my signature in presence of two witnesses.
