IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 26,976, dated January 31, 1860.

To all whom it may concern:

Be it known that I, JosEPH L. DUTTON, Jr., of Cherry Lake, Madison county, Florida, have invented a new and useful Improvement in Flows; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in the arrangement of devices described hereinafter and forming a plow which can readily be altered to cut deeper or shallower furrows, and the handles of which can be adjusted with facility.

On reference to the accompanyingdrawings, which form a part of this specification, Figure 1 is a side view of my improved plow; Fig.2, the same with the parts adjusted to a position differing from that in Fig. 1; Fig. 3, an end view of Fig. 1; Fig. 4, a detached perspective view of part of the plow.

Similar letters refer to similar parts throughout the several views.

A is the, beam of the plow, consisting of a plain bar of iron or wood, with an eye, a, at the front end, to which the single-tree is connected.

B is the toe of th plow, and O is the heel, forming the landside, both having near the top a series of holes for receiving the bolts which secure them to the beam. The toe B has an enlargement, b, in which is a slot for receiving the heel. On the under side of the latter, where it passes through the enlargement, are a series of notches, d, and on the bottom of the slot are one or more pointed projections adapted to the notches of the heel, which is firmly secured to the toe by a wedge, e, passing through the slot and forcing the notched edge of the heel into gear with the projections of the slot.

Twohandles, D and D, are secured at m to the beam A, one handle on each side. These handles are connected together near their outer ends by the cross-bar G, to which are connected the hooked ends of the staple H, which embraces the adjusting-bar I, the latter having in front a series of notches, each of which is formed to fit the cross-bar G, a wedge, f, serving to secure the adjusting-bar firmly to the cross-bar.

As illustrated in Fig. 1, my improved plow is adjusted to cut a shallow furrow in the ground. When a deeper furrow is required the wedge e is loosened, when both the heel and toe can be readily moved farther from or nearer to each other at pleasure. It will thus be readily seen that the heel and toe may be made to project more or less from the beam, and that the depth of the furrow can be reg11- lated by this adjustment.

When adjusted to the desired point the wedge e is driven tight into its place, the pointed projection in the slot fitting to the notches on the heel, so that the heel and toe are secured firmly together until the key is again slackened.

When the position of the handles has to be altered the wedge f, which passes through the staple H, is slackened, when the handles may be raised or lowered until the cross-bar fits one of the higher or one of the lower notches in the adjusting-bar I, after which the wedge is tightened and the adjusting-bar, handle, and cross-bar firmly secured together. The'bar I thus serves the double purpose of affording an adjustment for the handles to suit the height of different attendants, and of securing the said handles rigidly when adjusted.

It will be seen on reference to Fig. 3 that both the heel and the toe of the plow have an offset or bend, in order that their lower ends may be directly under the beam and in the line of draft, thus preventing any undue lateral strain on the handles, which would take place if the lower ends of the heel and toe were situated out of line with each other.

Near the lower end of the heel G is a hole for receiving a bolt, by means of which a landside of any desired shape may be attached.

It will be readily seen that the plow constructed as above described may be quickly taken apart and packed into such a suitable form as to render it especially applicable for use in extensive and partially-cultivatedfarms.

What I claim as my invention, and desire to secure by Letters Patent, is-- The arrangement of the beam A, notched adjusting-bar I, handles D, cross-bar Gr, hooked staple H, and wedge F, with the notched heel O and notched and slotted toeB, the whole of the parts being constructed for joint adjustment, as herein set forth.

In testimonywhereofI have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH L. DUTTON, JR.
