Letters Patent No. 83,519, dated October 27, 1868.

IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J AMES MALLON, of Lockport, inthe county of Will, in the State of Illinois, have invented an Improved Cultivator; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and'to the letters of reference marked thereon, making apart of this specification, in which- Figure 1. is a longitudinal elevation of my invention, with one of the wheels removed, to give a clear view of the construction.

Figure 2, atop view of the same Figure 3, an elevation of the forward end.

'Figure 4, drawing 2, an enlarged elevation of the draught-attachment.

Figure 5, a view of the under side of the oscillating frame, which regulates the positions of the shovels.

This invention relates to that class of cultivators which are run on wheels, and carry the operator; and its nature consists-- First, in combining handles with an oscillating frame, and the braces which support the shovels, by means of which the hands and feet maybe used to guide said shovels when hilling corn and other crops.

Second, in the use of double v-bracesfor supporting the rods of the shove1s, and preventing the latter from having a motion independently of each other. This arrangement is important, for the simple straight rods are not suflicient for this purpose, unless made so heavy as to be cumbersome.

Third, in adjustable braces, jointed to the shanks of the shovels, and arranged to slide on the elevating-bars, by which means, and jointed shovel-shanks, the shovels may be adjusted to run any required depth in the ground,'and arranging said elevating-bars by means of spools on the draught-rods, so that they may be set to bring the shovels to or from the row to be tilled, as the case may require.

Fourth, in the arrangement of elbow-levers, jointed.

,to the draught-rods, and connected with an evener by chains or rods, by means of which the draught-points are located in such positions as will cause the cultivator to run easily, and without the usual strain on the tongue.

Fifth, in the use ofpeculiar hill-protectors, pivoted I to the bars of the inner shovels, and arranged to drag on the ground, and prevent the earth from in iu'ing the corn in the hill, when thrown from the shovels.

v In order to give a clear understanding of my invention, I have marked corresponding parts with similar letters and figiu'cs, and will now give a detailed description.

A represents a substantial wooden frame, supported on an axle, (J, and wheels, D, similarly to the frames of other cultivators', which are used to support a part of the gearing.

H H represent two loop-frames, made of metal, and rigidly attached to the under side of the front of said frame, and to support two draught-rods, 1 1, figs. 1 and 3, to which the'bars F F, which support the shanks J J of the shovels, are attached.

These bars F F are made of any suitable material,

I the rock-shait W, and is made to work in a slotted segment, X, attached to the axle O, and having one or more notches made in the side of the slot for holding the lever in position when the bars F F have been raised up, so as to throw the shovels out of the ground.

I do not, however, claim the raising-device as new of itself, as similar arrangements have been used before.

J J represent the shanks of the shovels, pivoted at their upper ends to the bars F F, and held in position for use by adjustable braces G G'. These braces are an important improvement, and should be made of iron and pivoted to the shanks J J, as seen at fig. 1, and looped round the bars F F, near their front ends, and held in position there by means of bolt 3, either put through slots in said bars, or just below them, the object being to adjust the braces on the bars, and thus regulate the depth of the shovels in the ground, independently of the raising-devices above referred to, and at the same time hold them rigidly in position when set for use. I

f f represent rods, hung to a cross-bar, g, and extending downward alongside of the inner braces G, and locked in lugs, R, attached to their inner sides, and used for steadying the shovels, and preventing them from having a motion independently of each other. These rods I do not consider new, but the braces P 1 shown at fig. 3, are new, and very important for holding the rods in place, and from springing. And as the braces are attached to the same bar as'the rods, and fastened to their lower ends, they will not be in the way of the corn. This arrangement requires much less material, and provides a substantial support for the shovels.

The evener is pivoted to the tongue B, at 4, and has rods, 1) b, pivoted to its ends, and to elbow-levers I Q, figs. 1 and 3. These levers are pivoted to the rods 1 1, and between the bars F F, thus providing a draughtattachment directly atthe ends of the bars which support the shovel-shanks, and also at such a point as will best relieve the tongue from strain.

Spools T T, fig. 3, are put on rods, 1 1, and are used in changing the bars, F, when they are to run more closely together, This construction is shown more clearly at drawing 2, fig. :Lf'Wltll one of the spools removed.

The device for giving a lateral motion to the shovels is as follows:

A bar, 5, fig. 5, drawing 2, is put lengthwise with the tongue B, and pivoted to its underside at 6, and

its ends are made to operate in loops, 1 7, the former being attached to the under side of a brace, Q, fastened to forward ends of handles E, and the latter to the under side of the bar g, which supports the rods 7,.and braces, P, fig. 3. .The bar I is hung to the same elips which support the rook-shaft \V, 2, and arranged to have a reciprocating rnotion longitudinally when the bar 5 is made to swing on the pivot 6.

By means of this arrangement, the feet can be made to rest on lugs or stirrups, (I (I. l and .2, attached to the jointsof the shanks J J, and the handles E E- grasped by the hands, and used in conjunction, for mo 'ing the shovels to the right and left, as desired wh en cultivating arow.

The hill-protector K is jointed t0 the brace G, and has notches in the end which drags on the ground, in order that it may be light, and prevent the earth thrown from the shovels from c vering the hills of corn when small.

Having thus described my invention,

I desire to seem-e by Letters Patentof the United Sta-tes 1. The handles E, hraee Q in ooiuliination with the bar 5, pivoted to the under side of the tongue, reciprocating litll' hraees l, rods 7, and braces G, for giving a lateral motion to the shovels, as set forth.

2. The braces G G, in combination with bars F F, shanks J, and stirrnps r1, suhstantialtvas set forth.

it. The combination of the draught-rod 1 l, spools "1, bars 1 I earns and lever X, snbstantiall'as set forth.

4. The hill-protector K, pivoted tot-hebraee G, and arranged substantially as set forth.

JAMES MALLON.
