IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 42,646, dated May 10, 1864.

. thereon.

Figure l represents a plan view of our machine. Fig.2representsasideelevation; Fig.3, a longitudinal vertical section. Figcis a front elevation of the guards and stock, hereinafter described.

Ihe letter A, in Fig. 1, represents the body or frame, which is made of seantlin g of suitable size.

B represents the axle-tree, tothe ends of which the wheels D are attached.

O represents two pieces of scantling placed under the axle B and confined to B by bolts. The scantlngs O extend sufficiently far in the rear of axle B to support the platform E, on which the drivers seat Frests. The scantlings Oincline at a small an gle in the direction of the tongue G and reach a point near the junction of the tongue G and the hounds h, being connected then and braced together by the bar j. The bar j is fastened on the top of the tongue G and the hounds h by means of a bolt through each. The hounds hand the tongue G are tied together by two similar bars fastened in the same way-one near the outer ends of hounds It and another sucientl y in advance of the rst to admitof the handles lc passing between them. These two bars are designated by the letters m and a. The tongue G extends as far'as bar m, to which it is attached by a bolt, as already mentioned. The handles lr, to the lower ends of which the shovels are attached, incline t0- wa-rd each other at a slight angle, are placed immediately behind the bar n, and are fastened to a with a bolt. Besides the lateral inclination of handles Ic, their lower ends are in advance of the upper, so that when the handles are in position they are at an angle of more than forty-live degrees. Near their upper end the handles are bound together by a tie, O.

Prepresents ashaft, to thelower end of which the guard'wheels a a are placed-one on each side of shaft P. The 'upper end of P has a slot init anda boltpassingthrough the slotinto the side of thctongue G. By thcmeansof the bolt and slot, P can be raised or lowered, as the case may require. As an additional support to shaft P, it has another slot about its center, running at right angles with the iirst, through which a bolt passes into the cross-tie s, the tie s binding the handles together at that point.

The object of the guard-wheels is to defend the young corn from clods at the moment that the shovels on k are turning over the earth on each side of the hills.

To one who is acquainted with the culture of corn, and knows how much time is lost by the plowman in uncovering the tender plant, the

advantage above referred towill be considered of great importance. Y k

In order to give additional strength to the lower part of handles 7c, they are braced by an iron rod one end of which is attached to astaple in k, and the upper end penetrating the bar j. The end passing throughj has several holes in it, and by means of a bolt inserted into one of these holes the rod can be raised or lowered,

thereby increasing or diminishing the angle of the handles It'.

Trepresents two standards placed in the rear of bar m and bolted to the inner side of the hounds h. The standards T are adjusted at the same angle as the handles k, and are braced to the hounds h with iron rods. The stand-- ards' T are designed to have shovels attached to them similar to those on handles 7c.

V represents a foot-lever, one end being near the drivers seat F and the other extending under the bar m. By the means of this lever, which is hinged to the top of axle B, the barm can be raised and the shovels on handles k and standards 'I thrown out of the ground, so as to enable the machine to pass over obstructions that may be in the way.

It will be observed that in operating our cultivator both sides of a row of corn are plowed at the same time, thus reducing the labor of cultivation one-half. In addition to this our guard, as above described, performs its office faithfully and renders all stoppage on the part of thel operator unnecessary.

We are aware that it is not new to provide a cultivator with a guard to protect young plants from clods, and also that it is common to raise cuitivatorframes by means of footlev= ers 5 but,

Having thus described our invention, what and extending forward beneath the bar m and we claim as new, and desire to secure by Letters Patent, is

1. The 'rotary guards a a, mounted upon the stock P and employed in combination with inner cultivators, k k, in the manner and for the purposes described.

2. The foot-lever V, fulcrumed upon the axle backward into convenient; proximity with the sent F, as und for the object; specified.
