To aZZ whom it may concern.-

Be it known that we, SAMUEL E. MORRAL and JOHN MORRAL, citizens of the United States, residing at Morral, in the county of Marion and State of Ohio, have jointly invented certain new and useful Improvements in -Walkirig-Cultivators; and we do declare the following to be a 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 the letters and figures of reference marked thereon, which form a part of this specifica- Men.

Our invention relates to improvements in cultivators.

Our invention relates to that class of cultivators which are mounted upon wheels and having an elevated axle, and which are termed walking-cultivators.

Our invention consists in certain improvements in the evener or doubletree and its auX- iliary attachments, by which it is better adapted for equalizing the draft of the machine and at the same time obviating side draft, causing each horse in the team to draw his own plow-gan g also, of an improvement in the spiral springs for easing the plows, they being made adjustable; also, of improvements in attaching and adjusting the shovels, whereby almost complete universal adjustment of the latter is effected.

Figure 1 is a side elevation of our improved cultivator. Fig. 2 is a top view of the same. Fig. 3 is a detail of the hook-bolt which secures the tongue to the axle. Fig. 4 is a perspective view of the axle, tongue, and double tree with their attachments. Fig. 5 is a vertical section through line .19, Fig. 2, enlarged. Fig. 6 is a view of the doubletrce-plate from the under side. Fig. 7 is a side elevation of the clevis, with one of the half sections of pintle-sleeve. Fig. 8 is a horizontal section of one-half of the cleviscoupling. Fig. 9 is a side elevation of one pair of the pivoted swinging bars which supports the clevis end of plow-beam, the axle being cut away to show the device for pivoting these bars to a block on the latter. Fig. 10 is a rear elevation of the same. Fig. 11 is a side elevation of one of the plow-shovels as attached to its stock.

and rod which extends in opposite directions through the coil of the spring. Fig. 17 is a view from the under side of the cap of the spring coil.

The object of our invention is to equalize the draft, at the same time requiring each horse to pull his own gang-plow, so as to re lieve the cultivator of side draft; also, to allow the plows to be shifted nearer to or farther from the corn-rows. The clevis ends of the plow-beams are supported by swinging bars, which latter are pivoted to a clamp-block attached upon the axle upon each side of the tongue, so as to allow either one of the plows to be drawn forward of the other without changing the line of draft, as desired. The evener or doubletree is long and is pivoted within a stirrup to a plate under the tongue of the cultivator. The evener is provided with swinging hitch-irons at the ends.

These hitch-irons are connected by link-rods with the plow-clevis. Besides these connections a long link-rod connects the plow-clevis with an eyebolt on the doubletree nearer the tongue, so that the pull is divided between the two points mentioned, thus making an evener of the doubletree and its hitching attachments, and allowing greater scope to the movement of these parts.

A is the axle, made, as usual, in a single piece with an elevated right-angled arch.

B is the tongue, mounted upon the axle and secured thereto by a hook-bolt d at the middle of the latter. Each side of the tongue at the proper distance apart is a clamp-block O clamped upon the axle. The lower section C of this block C consists of an oblong piece having parallel sides and grooved lengthwise to allow the lower half of the axle A to lie therein. From the middle part lateral flanges extend, and a cap O (similar to that over an ordinary journal-bearing) extends over the axle at the middle part of the clampblock, and is secured by bolts 2 2, as seen best in Figs. 1, 2, and 9. The lower part of section 0 is formed with a depending lug a at each end, which is recessed outside to receive the ends of the parallel swinging bars of, by which the clevis ends of the plow-beams are supported. By reference to Figs. and it will be seen that these bars are suspended upon a bolt 1), which extends through the lugs in each clamp-block, and are free to move forward or backward with the move ment given to the plow-beams D D. Cast upon the cap 0 is a hanger c, which extends toward the rear over each plow-beam. 0n the upright of the hanger c is an eye 'i, by which a link-rod (Z connects it with a loop washer on the ends of the cross-tree f, bolted to the tongueback of the doubletree. The rear end of hanger c has an eye 1." formed on it, and is connected with the plow-beam by an adjustable spiral spring H, (a description of which will be hereinafter given,) the lower end of which hooks into an eye back of the clevis. The plows are thus con nected over-the axle with I the draft-bars formed by the doubletree and doubletree-plate, as well as beneath it, so that the strain in either direction is brought to bear on these last-named parts.

The clevis O is secured to the lower ends of the pivoted swinging bars a by a crosscoupling I, which allows the plows to be moved up or down or sidewise. This coupling consists of an upright sleeve 4, in two half-sections, pivoted upon the two short vertical pintles f, extendinginwardly from the upper and lower limbs of the clevis. The exterior of this sleeve is angular, preferably of octagonal shape, and is inclosed from either side at the middle part by a sleeve-piece b recessed to fit against it at right angles. This sleeve-piece incloses the hub i of the cylindrical end piece 5 of the coupling. A vertical recess 4* is cut in the piece 5 for the lower end of the bars (L The sections b and 5 are of general cylindrical form, and a central hole through section 5 and the upright sleeve 4 admits a bolt 6, which secures the ends of bars a to the clevis-coupling. (See dotted lines, Fig. 4E, and also Fig. 8, which latter figure s)hows the sections of onehalf the coupling.

The clevis C is provided with the usual series of holes n n in the front part for the draft-rods. E is the doubletree-plate, which is of cast metal with a raised top surface and depressed on the under side to give it lightness and strength. It consists of a f ront portion transversely oblong with circular ends and having a large circular hole in each of the latter to reduce the weight. Its rear portion is formed into a cross-tree f, which extends across the line of the tongue B, and it is bolted to the under side of the latter by bolts a a.

In Figs. 5 and Git will be seen thatabroad flat stirrup e extends across the under side of the evener-plate E, within which the doubletree F is pivoted. A heavy diagonal brace 12 connects the collar 0 on each spin dle of the axle with the end of the cross-tree f from each side, and is fastened by a bolt 78, which also passes through the loop-washers 3, over which a nut is screwed down upon them.

The evener or doubletree F is of unusual length, and has each side of the plate E, nearly in line with the ends of the cross-tree, an eyebolt 7t, depending from the underside. These eyebolts flexibly connect it by linkrods with one of the upper holes of each clevis. From one of the holes under these, in the clevis, the jointed link-rods h extend from each side diagonally outward, and are connected with the vertical limb g of the swinging hiiTChllOllS G. These latter consist of a right-angled triangular frame of rodiron, the top and outer or vertical bar g being straight, and this latter forming the point of attachment for the sin gletree of each horse, there being holes in it for that purpose. These hitch-irons Gr G swing from eyebolts 7x) 711011 the evener F at their upper angles. The evener F has a swing of about one foot, and as the inner link-rods b are in one piece when one side of the evener is drawn forward the link-rod b on the opposite side pushes against the clevis and forces the swinging bars on that side back, thus requiring each horse to pull his own plow to keep both in line. The hitch-irons G have a considerable swing forward before the jointed rods h hare straightened out, allowing free movement of each horse in the team.

The movements of the evener F are shown in dotted lines, Fig. 2.

Thespiral springs H H are made adjust able. By reference particularly to Figs. 15 and 16 it will be seen that a fiat bar 1' extends up through the coil, its lower end havin g a hook 2' formed on it which engages eye 11 on the plow-beam. Rod 7, on which the upper hook h is formed, is doubled and straddles the Hat bar 2' and extends down on either side of the latter to the bottom of the coil, where its ends turn outward in the form of hooks 71 71. catching under the lower end of the coil and compressing the latter as the rod 7 is pulled upward in lifting the plow. A cap j, Fig. 17, having cross-slots w and o in it, allows the movements of bar "6 and rod 7 through it, and is secured to the top of the coil by a set-screw 8, which passes through the cap 7' from one side and engages the edge of bar 2' as seen, Figs. 1 and 15. The spring is compressed by pulling rod 7 and bar 6 in opposite directions, and the collar j is secured upon the latter at any point desired in the adjustment. In Fig. 15 the upper and lower ends 0 and c of the coilare shown entire, the rest beingin vertical section. The shovels of the cultivator are fitted with devices for adjustmentin every possible direction required, as seen by dotted lines in Figs. 11, 12, and 13. It will be seen by these that the shovel S is fitted with a long iron loop (1, bolted longitudinally upon the back of and in the middleline of the shovel. This loop is concave (in crosssection) on the rear or outer side, as seen in Fig. 13, and rounded upon the inner or front Side to allowit to beheld on ablock rbythe stirrup-iron s, which latter clamps it to the stock 1). The stock 1) is made of a single piece of flat iron bent in the middle to form the lower end and leaving an open spacep between its sides. A block 0*, concave longitudinally and convex transversely on its front face and having straight shoulders fitting against the inner edges of the stalk 1), lies upon the latter and hasan upper and lower limb r extending at right angles from each end of the block back through the opening in the stock, each limb r having a head t on the end to retain it in place on the stock.

hen adjusted in place, the shovel, block, and stock are all clamped firmly together by the stirrup-iron s, which passes through the loop-iron q, over the block 1" and the stock 3, to the rear of the latter, between the heads it of limbs r, where it is securely fastened by a long plate-washer .9, extending across the stock, and nuts u u screwed against said plate-washer.

The shovel can be adjusted up or down upon the stock (retaining the same angle to the ground-surface) by simply loosening the nuts 11. u and sliding the block, shovel, and stirrup-iron in the direction desired together on the stock. To throw the dirt toward or from the corn (while retaining the block r in the same position on the stock) it is only necessary to incline the shovel toward either side, as desired, as seen in Fig. 11.

To give the shovel a greater or less angle to the ground-surface, it is loosen ed by unscrewing the nuts u u and its upper end thrown forward or backward by partial rotation around the loop of the stirrup-iron s as a center, and sliding the loop-iron q in the concave of block 0", so that any degree of inclination may be given to the shovel by the means referred to, and as shown in the figures.
