VALTER XV. PARSONS, OF DERBY LINE, VERMONT.

lMPROVEWIENT IN WHEEL-FLOWS.

Specification forming part of Letters Patent No.

l5L617, dated June 2, 1874; application tiled February 14, 1874.

To all whom Ait 'may concern:

Be it known that I, WALTER W. lnnsoxs, of Derby Line, in the county of Orleans and State of Vermont, have invented a new and valuable Improvement in W'heel-Plows; and I do hereby declare that the following is a full, clear, and exact description otl the construction and opera-tion ofthe same, reference bein had to the annexed dra-win gs, making a part ot' this specification, and to the letters and tigures of reference marked thereon.

Figure l of the drawing is a representation ot' a sectional view otl my device. Fie'. 2 is a plan, and Figs. 3, 4, and 5 detail, views ot' the same. Fig. 6 is a longitudinal sectional, and Fig. 7 a plan, view or' the same.

This invention has relation to plows which are attached to carriage-frames, as will be hereinafter more fully described and claimed.

The following' is a descri1j tion ot my improvements In the annexed drawings, Figs. l, 2, 3, 4, and 5, l have represented my improved plow and its carriage.

A A designate carriage-wheels on an axle, A', to which latter two beams, B B, are pivoted. These beams extend back of the axle A', and are connected together at their rear ends by a rocking cross-baiyvO. I) designates the draft-tongue, the rear forked ends ot' which are secured to the axle A. E designates the plow beam or stock, which is connected by a chain, a, to the axle A', and by another chain, a', to an angular lever', I), which lever is pivoted between the rear ends of the draft-tongue, and connected to ahand-lever, b, by a link, b2. By this means the front ot' the plow can be raised and depressed. The rear curved portion of the beam E is rigidly secured to the rocking bar O, and the lower end ot this curved portion ot' the beam is connected to the plow, as will be presently explained.

The plow is constructed with a reversible mold-board, Gr, which is convex transversely, concave longitudinally, and which tapers from its rear end to the pointc. The front portion of this mold-board Gr is constructed with two tapered tins, g g, which terminate in the point c. Then one of these ns f/ is in a horizontal position it serves as the share of the plow;

the other iin g being in a vertical position, it serves as the colter; and the side of such iin next the sod is the land-side, (indicated by letter e, Figs. l and 4,) while the side at right angles to that last named is the sole of the plow. The lower portion of these two sides e are extended back to form a land-side and sole-bar, h, which, in cross-section, is rectangular, and to which a tubular block, f, is rigidly secured. This block j' receives into it the rounded end ofthe beam E, which allows the plow to be turned over toward the right or left. The said rounded end of the beam is secured into the block f by lneans of a pin, t', which is applied into a rectangular slot, i', made info this block, which slot and pin will allow the plow to be turned onequarter either toward the right or left, but no farther. A pin, j, is east on one of the wings of the moldboard G, to which piu the lower end of a rod, L, is pivoted, which rod is connected by a ljoint to the long arm of an angular lever, k1, which is pivoted to the rear forked end of the drafttongue D. The short arm of lever k1 is connected tol a locking-lever, J, by means of a rod, k2. This lever J is attached to the draft tongue by means of a pivot-bolt, n, which passes through an oblong slot, n', made through it, which slot allows it to be moved lengthwise, as well as to be vibrated.

It is by means ot' the lever J that the plow can be turned either to the right or left by a person mounted on the machine.

XVhat I claim as new, and desire to secure by Letters Patent, is-

l. The beam E, rocking bar O, pivotcd bars B, chain a, axle A', connecting-chain a', and angular lifting-lever b, which is connected to a hand-lever, all combined substantially as described.

2. The reversible plow, in combination with the beam E, slotted lever J, rods k k2, and angular lever kl, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

NVALTER XV. PARSONS.
