IMPROVEMENT IN ADJUSTABLE LANDSIDES OF PLOWS.

Specification forming part of Letters Patent No. 7,994, dated March 25, 1851.

To all whomit may concern Be it known that we, GEORGE HEFFLEY, SAMUEL CoNRAD, and JAMES WIGLE, of the town of Berlin, in the county of Somerset and State ot' Pennsylvania, have made certainnew p and useful Improvements in Plows, which are described as follows, reference being had to the drawings hereunto subjoined, and making part of this specification.

The nature of our improvements in plows consists in the arrangement, combination, and use of a separate adjustiveheel and restattached to the land-bar for the purpose of regulating and governing the depth of the furrow at pleasure with great ease and exactness, and which prevents the wearing away of the landbar, as is experienced in the ordinary plow, and, in addition, entirely supersedes the necessityof the usual separate land-bar; also, in extending the mold-board onthe inside thereof back to form a flange or support upon the reversi-ble bar-point and landside, and to which they are secured; likewise, in forming upon the two sides of the reversible bar-point transverse long and short notches, into which fit corresponding long and short projections or locks formed on the upper side of the landside and under side ofthe iiange or extension of the m0ld-board,t`or the purpose of more effectually locking, holding, and securing the reversible bar-point from moving in any direction after being adjusted.

A more particular description of the features above noticed will be found hereinafter.

Figure 1 is a perspective view of the inner, under, and front sides of the mold-board, the land-bar, reversible bar-point and share being removed. Fig. 2 is a perspective view of the land-bar, the reversible bar-pointbeing in its proper position upon the land-bar. Fig. 3 is a perspective view of the land-bar, the reversible bar-point being removed and the adj ustive heel and rest being lowered. Fig. et is an elevation of the inside of the land-bar, showing the adjustive heel raised. Fig. 5 is a view of the land-bar and adjustive heel and rest inverted. Fig. 6 is a perspective view of the share detached. Fi g. 7 is a plan of the reversible bar-point. Fig. 8 is a view of the opposite side of the same. Fig. 9 is a perspective view of the adjustive heel and rest detached. Fig.

1() is an elevation of the landside of the plow with the parts combined.

The references used in the specification designate the same parts in the several gures.

The mold-board A, the land-bar B, the reversible bar-point U, cutter D, and share E are made and arranged in the manner represented in the drawings. The cutter D is tted in arecess formed in the landsideof the sheth D and iront edge of the mold-board, and secured by a screw-holt, d, and nut d', its inner edge resting against a shoulder, D2, formed by the recess. t

E isthe share, its front eudiitt'ing into one ot' the oblong notches G in the reversible barpoint C, and its outer or back end resting upon and supported by a projection, E, cast on the lower corner ot' the mold-board, and secured by a screw-bolt and nut.

F' is a flange cast on `the sheth, by which itV is bolted to the beam in the usual manner.

The reversible bar-point C is provided with oblong notches G near each end and equidistant from the center and on opposite sides, as representethin to which the lower corner ofthe cutter and inner front corner ot the share respectively fit. This bar-point is also provided with `oblong niortises I I ou each side of its center, longitudinally through which the confining screw-bolt b passes, for allowing it to be moved forward as it Wears away and reversed and inverted in its position when desired.

J is a depression formed in the land-bar, on the under side thereof', extending from near the point back beyond the conningscrew-bolt, for reducing the draft ot' the plow or friction thereon.

K is a bead or rib cast on the upper edge of the land-bar, against which the edge ot' the bar-point rests, for keeping it in its proper-position.

c is the opening in the 1and-bar through which the confining-bolt b passes.

c' is an opening or hole in the flange or projection of metal, U, through which the confining-bolt b also passes to receive the nut f on its upper end, which nut screws against and upon the flange or projection U, and thus confines the land-bar and bar-point to the moldboard.

L is the adjustive heel and rest, made of steel or wrought-iron, for giving the furrow a greater or less depth. It is iitted to the rear portion ofthe land-barin a recess, M, formed therein to receive the vertical side of the said heel, and secured by means of a screw-bolt, N, passed through a slit, N', in the land-bar, to receive a nut, o, on its inner end, and also by a hook, P, caston its front end and projecting upward and hooking over a similar-formed hook, Q. The bottom or horizontal portion of this adjustive heel is made to taper from its rear end to the hook P, and is ofa width at its rear end about twice the thickness of the land-bar, to form a proper support for the plow in elevating its rear end to increase the depth ofthe furrow. It is also turned at right angies and extends to near the top ofthe'land-bar, and equal in length to its bottom, and serving the double purpose of saving the land-bar from wearing away by friction, and dispenses with the usual separate land-bar of the landside.

R is a plate, being a continuation of the heel L, and is secured in front thereof by dovetailing a portion or projection, R', of the land-bar in a notch or openingin said plate and securing it firmly by a screw, S. On the end ofthis plate It next to the hook P is cast another hook, Q, in a reverse position to the hook P, and over which, the hook P catches or laps, and upon which the heel turns in elevating or depressing its rea-r end to govern the depth ot' the furrow.

T is a set-screw secured in a female screw formed in a lip or projection, T', on the inside ot' the land-bar, for the purpose of preventing the heel rising, in addition to the screw-bolt N, when depressed to elevate the rear end of the plow, by screwing the said set-screw upon and against the bottom orhorizontal portion of the heel.

Uis theange or extension of lnetahcast with the mold-board on the inside thereof, and projecting back, forming a support and seat for the mold-board upon the reversible bar-point and land-bar, and to which the latter are secured by the confining screw-bolt b.

e e are short notches near the ends of the barpoint and on both sides ofthe same, which admit the short projections t t formed on the front end of the land-bar, for preventing roots, &c., getting between the bar-point and point of the land-bar.

ccare long notches extending entirely across the bar-point, in the middle thereof,into which fit corresponding locks or projections,w w, on the upper side of the land-bar and bottom of the flange or extension U as the bar-point is moved forward or renewed, and which also hold the bar-point securely, in addition to the short notches e and projections t t.

When it is desired to deepen the furrow the screw-boltNis loosened and the heel depressed by the set-screw T, which elevates the rear portion of the plow, and thus causes it to enter deeper into the soil. The screw-bolt N is then clamped, and the set-screw T, being in contact with the horizontal portion of the heel, prevents it rising.

Having thus described our improvements in the plow, we wish it to be understood that we do not cla-im the employment of an adjustive plate for elevating the rear portion of the plow to regulate the depth ofthe furrow; but

vWhat we do claim as ourinvention, and desire to secure by Letters Patent, is-

Providing a righ t-angled heel-plate, L, with a hook, P, for theinrpose of interlocking with a hook-shaped projection, Q, attached to the landbar, forminga hook-joint, said heel-plate L forming the bottom and side of the land-bar, and having its rearward portion susceptible of vertical adjustment by means of a screw, T, and, when adjusted, being clamped by a horizontal screw-bolt, N, its shanky being placed in a segmental slot to admit of its moving withl the heel-plate, as described.

In testimony whereof we have hereunto signed our names this 26th day of Julie, in the year of our Lord 1849, vbefore two subscribing witnesses.
