REVERSIBLE PLOW.
SPECIFICATION forming part of Letters Patent No. 430,307, dated June 17, 1890.
Application filed May 1, 1890. Serial No. 350,166- (No model.)
To all whont it may concern:
Be it. known that I, HAZEN R. UNDERHILL, a citizen of the United States, and a resident of Derry, Rockingham county, State of New Hampshire, have invented a new and useful Improvement in Reversible Plows, of which the following is a specification.
My invention relates to that class of reversible plows in which the mold-board and wing turn upward and under the beam; and my object is to produce a plow that will be efficient in action, light, strong, and economical in construction, and easy to handle and operate.
I do not claim, broadly, a plow in which the mold-board and wing turn under the beam, or a plow-body whose landside and shoe are at right angles to each other, as I am aware that these features are old in reversible plows.
My invention consists in the peculiar arrangement of the mold-board and wing, the supporting-standard interposed between the two, and in the locking device whereby the body of the plow is held in its proper position to the beam and additional strength imparted to resist the strain and leverage on the plow-point, as will be hereinafter more fully set forth and described.
In the drawings, Figure 1 is a side elevation of my improved plow, showing the plowshare, mold-board, wing, lever, (X50. Fig. 2 is an elevation showing the side of the plow opposite to that shown in Fig. 1. Fig. 3 is a rear elevation showing end of plow-beam, the rear standard attached thereto and rear View of plow-body and wing. Fig. at is a perspective elevation of the beam, standards, lever, and plow-body, with mold-board and wing removed.
In the drawings. like letters indicate like parts.
A is the plow-beam, and B B the handles thereon.
E E are the supporting-standards, preferably made from a flat barof iron and attached to the under side of the beam by bolts, as shown in Figs. 1, 2, and at.
O is the plow-body, having detachable point C, said point being secured by bolts, so as to be readily removed in case a new point is to be substituted for the old one.
D is the rearpart or wing of the mold-board,
having its reverse movement in the rear of supporting-standard E, said standard passing through slot L. which divides the moldboard from the wing D. This wing is rigidly bolted to the plow-body through a cross-bar D, said bar conforming to the transverse curvature of the wing, said bar being bolted or otherwise secured at each end to the plowbody immediatelybehind the front standard E, as shown in Figs. 2 and 4.
G is the lever, passing through and fulorumed on the rear standard E. The lever is held in place between the two braces 13 by a bolt passing through said braces and through an elongated vertical slot on the inner end of said lever. The curved edge of the rear crosssection H is provided with two notohesone at each endas shown at h in Figs. 3 and 4. By means of the spiral spring K the lever G is held in engagement with one of the notches, thus serving to keep the plow-bodyin its proper position either for right or left hand work,as may be desired. The reversal of the plow is secured by simply pressing downward on the outer end of the lever, thus carrying it-out of engagementwith the notch. Then bydropping the handles toward the mold-board side of the plow until the lever engages with the notch on the opposite side of the cross-section II and lifting the handles to their upright position the plow is ready for work.
F is a bolt or shaft that secures the body of the plow to the standards and beam. It passes longitudinally through the lower end of the rear and front standards E E and through the middle and rear cross-sections H H near the apex of their angle, and is secured in place by a nut on the end of said bolt.
L is a transverse slot separating the front or share part of the mold-board from the wing D, thus allowing of a free movement of the body of the plow, mold-board, and wing over standard E when the plow isbeing reversed. By thus arranging a supporting-standard between the mold-board and wing a light and yet strong construction is possible with less leverage and strain on the point of the plow than when the mold-board and wing are in front of the point of support.
The body of the plow is preferably provided with three cross-sections or plates H, H,
and S, arranged, as shown in Fig. 4:, at the rear, middle, and front of the plow-body and properly secured to the angles of said body.
To each edge of the angles forming the landside and shoe is bolted a steel cutter m, which may be removed for sharpening or be replaced by a new one, as may be required.
The mold-board in front of the standard E is preferably formed from a steel plate and secured between the angles to the cross-sections H and S by bolts or otherwise.
Additional strength and firmness are secured to the front standard E by means of braces B, extending from the lower end of said standard to the sides of the plow-beam, being attached to said standard and beam by bolts or otherwise, as shown in Fig. 4:. To these braces the plow-handles may be secured by bolts, sockets, or in any other approved manner.
\Vhat I claim as new and of my own invention, and for which I ask Letters Patent of the United States, is-
1. In a reversible plow, the combination, with a plow-beam having two supportingstandards bolted to the under side thereof, of a plow-body formed of two equal sides at right angles to each other, having cross-sections between and secured to said sides, and a moldboard and wing, as shown and described, and a longitudinally-arranged bolt running through the lowerends of said standards and through the rear and middle cross-sections of the plowbody near the apex of the angle thereof, forming the pivotal bearing for said body, substantially as set forth and described.
2. In a reversible plow havinga beam with front and rear standards, a plow-body consisting of share, shoe, point, mold-board, and wingrigidly connected together, as shown and described, said front standard interposed between said mold-board and wing through a transverse slot therein, whereby the wing when the plow is reversed turns between the two standards, substantially as set forth and described.
3. In a reversible plow having a beam and two supporting-standards thereon and plowbody constructed and arranged as shown and described, and a lever acting as a catch, passing through and fulcrumed on the rear standard and capable of engaging with the notches in the rear cross-section of said plow-body, whereby said plow-body is held in proper-position with the plow-beam, substantially as set forth and described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 18th day of April, 1890.
